Iglasi yeBorosilicate vs Soda-Lime yeebhotile zeCosmetic: Ukumelana nobushushu kunye nedatha yokuhambelana kweekhemikhali

TL;DR.Iglasi yeBorosilicate kunye neglasi yeSoda-lime azitshintshisani xa kupakishwa izinto zokuhombisa. Usapho lweBorosilicate lune-coefficient yokwanda kobushushu ejikeleze i-3.3 x 10^-6/K, lunyamezela ukutshiswa kobushushu i-ΔT emalunga ne-160 degrees Celsius, kwaye luhlangabezana ne-USP <660> hydrolytic class HGA 1. Usapho lweSoda-lime lune-coefficient yokwanda ejikeleze i-9 x 10^-6/K, lunyamezela i-ΔT emalunga ne-40 degrees Celsius, kwaye luhlangabezana ne-USP <660> hydrolytic class HGB 3. Isigqibo siqhutywa zizinto ezintathu: ubushushu bomgca wokuzalisa, i-pH yefomyula, kunye nobomi beshelufu ekujoliswe kuyo. Ukugcwalisa okushushu ngaphezulu kwe-70 degrees Celsius, i-pH yefomyula engaphantsi kwe-4 okanye ngaphezulu kwe-9, okanye ubomi beshelufu obungaphezulu kweenyanga ezingama-24 zonke zibonisa i-borosilicate. Ukugcwalisa ubushushu begumbi, i-pH engathathi cala, kunye nobomi beshelufu obuqhelekileyo kugcina i-soda-lime iyinto eqhelekileyo.

Iintsapho ezimbini zeGlasi: iBorosilicate kunye neSoda-Lime ecaleni

Iglasi ye-borosilicate yakhiwe nge-silica kunye ne-boron trioxide, kunye nomxholo we-B2O3 malunga ne-12% ukuya kwi-15% yefomyula. I-boron ithatha indawo ye-sodium kunye ne-calcium oxides ezenza iglasi ye-soda-lime, kwaye olo tshintsho lulodwa lubangela phantse yonke i-property difference. Ubushushu bokutshintsha kweglasi buphezulu, ukwanda kobushushu kumalunga nesithathu, kwaye ukuqina kweekhemikhali ngokuchasene namanzi kunye nezisombululo ze-asidi kuphindwe kaninzi.

Iglasi yesoda-lime yeyona nto isetyenziswa kakhulu kushishino lokupakisha izinto zokuthambisa. Le fomyula imalunga ne-70% ye-silica, i-15% ye-sodium oxide, i-9% ye-calcium oxide, kunye ne-magnesium, i-aluminium, kunye nezinto ezilandelelanayo. Ixabiso liphantsi ukuyivelisa, kulula ukuyibumba ibe yijiometri ebanzi yeebhotile zokuthambisa ezilindelwe yimarike, kwaye ingasetyenziswa kwakhona ngokupheleleyo ngomlambo olawulayo. Iimpawu ezifanayo ezenza i-soda-lime ingabizi kwaye isebenze ziyenza ibe sesichengeni sokutshatyalaliswa kobushushu kunye nokutsalwa kwe-alkaline phantsi kweemeko ze-asidi.

Izinto ezintathu ezidityanisiweyo ziqhuba phantse yonke idatha kule nxalenye yolu thelekiso. Okokuqala, i-boron kwi-borosilicate yinethiwekhi yeglasi yangaphambili, oko kuthetha ukuba ibopha ngqo kwi-lattice ye-silica kwaye ivelise isakhiwo esixineneyo nesizinzileyo kubushushu. Okwesibini, i-sodium kwi-soda-lime sisiguquli senethiwekhi, oko kuthetha ukuba ihlala kwizikhewu ze-lattice ye-silica kwaye iphuma xa ivezwe emanzini okanye kwizisombululo ze-asidi. Okwesithathu, ukungabikho kwe-boron kwi-soda-lime yikona okuvumela ukuba ifomyula ilungiselelwe ukucaca kunye nokwakheka endaweni yokumelana nobushushu okanye neekhemikhali.

Kumgca wemveliso, umahluko phakathi kweentsapho ezimbini zeglasi ubonakala kwimisebenzi emithathu. Sihlola i-cullet ngaphambi kokulayisha ibhetshi ukuze sigcine umbala kunye ne-coefficient yokwandiswa ngaphakathi kwebhendi echaziweyo yomthengisi. Silinganisa i-coefficient yokwandiswa kobushushu kwisampuli etsaliweyo ukusuka kumjikelo ngamnye wesithando somlilo, kwaye siyala nayiphi na isampuli edlula ngaphezulu kwe-0.2 x 10^-6/K kwixabiso elibhengeziweyo lomthengisi. Sijonga ubukhulu bodonga lwebhotile emva kokwenziwa, kuba ubukhulu bodonga bubo obumisela ukunyamezelana kwe-ΔT kumgca wokuzalisa ngaphezu kosapho lweglasi ngokwalo. Ibhotile ye-borosilicate yodonga ye-2.0mm idlula ibhotile ye-soda-lime yodonga ye-1.5mm kumgca ofanayo, kwaye sibona oku kuvela kwiikhawuntara zokulahla zomthengi ngaphambi kokuba kubonakale kwilebhu.

Isiphumo esisebenzayo kukuba kuyo nayiphi na ibhotile esetyenziswa kubuhle apho amaqondo obushushu angaphezulu kwama-60 degrees Celsius ngexesha lokuzaliswa, okanye nayiphi na into engaphantsi kwe-pH 4 okanye ngaphezulu kwe-pH 9 ngexesha lokuhlala kwayo eshelufini, ukhetho lweglasi luba lukhetho lokuba imveliso iya kufumaneka na kumthengi.ibhotile yeoyile ebalulekileyoUluhlu lugubungela zombini iintsapho zeglasi, kwaye ukhetho luqhutywa lusetyenziso endaweni yokhetho oluzenzekelayo.

Ukumelana Nokushukuma Okushushu: Umahluko we-ΔT kunye noko kuthetha kona kwiBhotile yeDropper ye-30ml

Eyona ndawo ibalulekileyo yedatha yomgca wokuzalisa ubuhle kukwahluka kobushushu ibhotile enokuphila phakathi kwecala elishushu le-filler kunye necala elipholileyo le-unscrambler okanye i-downstream conveyor. Usapho lwe-borosilicate lunyamezela i-ΔT emalunga ne-160 degrees Celsius phantsi kovavanyo oluqhelekileyo lobushushu. Usapho lwe-soda-lime lunyamezela i-ΔT emalunga ne-40 degrees Celsius phantsi kovavanyo olufanayo.

Kwi-hot-fill cosmetic line eqhelekileyo esebenza kuma-80 degrees Celsius kunye ne-downstream conveyor kuma-22 degrees Celsius, umahluko yi-58 degrees Celsius.iglasi ye-borosilicate ene-coefficient yokwandisa eyi-3.3 x 10^-6/KIbhotile idlula kolu tshintsho ngesantya sokulahlwa esingaphantsi kwe-0.1%. Ibhotile yesoda-lime iyasilela ngesantya sokulahlwa esiphakathi kwe-2% ukuya kwi-5% ekuqaleni kwaye iyawohloka ngakumbi njengoko umgca ufudumala. Umahluko we-2% ukuya kwi-5% ngumahluko phakathi komgca wokuzalisa osebenzayo kunye nomgca otsalelwa umva kumthengisi webhotile ukuze kuphandwe ngemvelaphi.

Kwi-cold-fill cosmetic line eqhelekileyo esebenza kwi-22 degrees Celsius kunye ne-18 degrees Celsius ephantsi, umahluko yi-4 degrees Celsius. Zombini iintsapho zeglasi zidlula olu tshintsho ngaphandle kwesantya sokwaliwa esilinganiswayo. I-borosilicate premium ayifanelekanga kwi-cold-fill lines, kwaye iindleko ezongezelelweyo zibonakala njengokunciphisa umda ngokuthe ngqo ngaphandle kokufumana inzuzo yokuthembeka komgca wokugcwalisa.

Umahluko wobushushu ubalulekile nakumthengi. Ibhotile ye-borosilicate ingasuka kwigumbi lokuhlambela elishushu elikumaqondo obushushu angama-38 degrees Celsius ukuya kwifriji ekumaqondo obushushu angama-4 degrees Celsius ngaphandle kokuqhekeka, yiyo loo nto i-borosilicate iyindlela eqhelekileyo ye-hot-fill serums ezithengiswa kwiindawo apho umthengi kulindeleke ukuba azifake efrijini emva kokuvulwa. Ibhotile ye-soda-lime ingasuka kwishelufu engama-30 degrees Celsius ukuya kwifriji ekumaqondo obushushu angama-4 degrees Celsius, kodwa ayinakusuka kwi-60 degrees Celsius hot-fill reject ukuya kwi-20 degrees Celsius wash-down ngaphandle kwe-scrap.

Kwifomathi yebhotile yedropper ye-30ml, imfuneko esebenzayo kukuba ibhotile ihlale ikwimeko yokwehla kobushushu bokugcwalisa obungama-50 degrees Celsius ukuya kwi-conveyor yokupholisa engama-25 degrees Celsius. Zombini iintsapho zeglasi ziyadlula kolu tshintsho, kodwa ibhotile ye-soda-lime ibambe umda omncinci wobushushu kwaye inovelwano ngakumbi kwimigca yokuma apho isiphelo esishushu sesigcwalisi siphola ngelixa iibhotile ziqhubeka nokutya. Ukuma komgca wemizuzu eli-10 kwi-50 degrees Celsius kunye ne-soda-lime kuvelisa izinga lokulahlwa elilinganisekayo kwi-conveyor elandelayo ebandayo; ukuma komgca ofanayo kunye ne-borosilicate akubonakali kwikhawuntara yokulahlwa.

Idatha yokuhambelana kweekhemikhali: i-pH 2 ukuya kwi-pH 11 kuzo zonke iifomyula ezisekelwe kutywala, ioyile, kunye namanzi

Ukuhambelana kweekhemikhali kulapho iintsapho ezimbini zeglasi zahluka khona kakhulu. I-Borosilicate kwi-hydrolytic class HGA 1 ayibonisi kulahleka kobunzima okulinganiselweyo, akukho tshintsho lwe-pH olulinganisekayo, kwaye akukho kuhlaselwa komphezulu okulinganisekayo kulo lonke uluhlu lwe-pH 2 ukuya kwi-pH 11 phantsi kokwaluphala okukhawulezileyo kwi-40 degrees Celsius kangangeenyanga ezili-12. I-Soda-lime kwi-hydrolytic class HGB 3 ayibonisi kuhlaselwa okulinganisekayo kuluhlu lwe-pH 5 ukuya kwi-pH 8, kodwa ihlaselwa elilinganisekayo kuluhlu lwe-pH 2 ukuya kwi-pH 4 kunye ne-pH 9 ukuya kwi-pH 11.

Indlela yokuhlasela kwi-soda-lime iqondwa kakuhle. Ii-ion zesodium kwi-lattice ye-silica ziyatshintshiselana nee-ion ze-hydrogen kwi-formulation, zinyusa i-pH ye-formulation kwaye zenze umaleko omncinci odibeneyo kumphezulu wangaphakathi webhotile. Izinga lokuvuza limalunga ne-0.1 ukuya kwi-0.3 micrometers ngonyaka kwi-pH 7, kodwa likhawuleza liye kwi-1 ukuya kwi-3 micrometers ngonyaka kwi-pH 3 okanye kwi-pH 10. Umaleko odibeneyo uncinci ngokwaneleyo ukuba ungabonakali kwaye utyebile ngokwaneleyo ukuba ungaphazamisani ne-pH-sensitive actives.

Kwimixube esekelwe kutywala enomxholo we-ethanol ongaphezulu kwe-20%, zombini iintsapho zeglasi azibonisi kuhlaselwa okulinganiselweyo. Utywala sisinyibilikisi esikhusela iglasi kwimixube kuba sicothisa impendulo yokutshintshiselana kwee-ion. Kwimixube esekelwe kwioyile kuquka imixube yeoyile ebalulekileyo, zombini iintsapho zeglasi azibonisi kuhlaselwa okulinganiselweyo kulo lonke uluhlu lwe-pH; ioyile ayitshintshisi ii-ion nge-lattice ye-silica. Sivavanya i-matrix yokuhambelana kweekhemikhali ngokuchaseneidatha yesalathiso sokuhambelana kweekhemikhali ze-borosilicate vs soda-limenjengesiseko, kuba idatha yokuhambelana kweekhemikhali epapashiweyo ibamba imeko embi kakhulu yamayeza kwaye naluphi na upakisho lwezithambiso oludlulayo kwiimeko ezifanayo zovavanyo ludlula uvavanyo lolawulo lwezithambiso ngokungagqibekanga.

Isiphumo esisebenzayo somxube weoyile ebalulekileyo kukuba ukhetho lweglasi luqhutywa yikhemikhali yeoyile ebalulekileyo endaweni yebhotile. Iioyile zecitrus ezinomxholo ophezulu wecitral, iioyile zeclove ezinomxholo ophezulu we-eugenol, kunye neeoyile zesinamoni ezinomxholo ophezulu we-cinnamaldehyde zonke zii-asidi ezithambileyo kwaye ziya kukhawulezisa ukuvuza kwe-soda-lime. Kwibhotile yeoyile ebalulekileyo ye-30ml eyenzelwe umxube we-citrus, uhlobo lwe-borosilicate lolona lukhuselekileyo. Kwi-mix yeoyile ethwala i-30ml engenazo izinto ezivuselelayo, i-soda-lime ilungile.

Kwizinto ezisebenza ngokhathalelo lolusu kwi-pH engaphantsi kwe-4, kuquka i-glycolic acid, i-lactic acid, i-salicylic acid, kunye ne-ascorbic acid formulations, i-borosilicate specification yeyona isemgangathweni. Ibango lobomi beshelufu beenyanga ezingama-24 kwi-pH 3.5 alinakufezekiswa kwi-soda-lime kuba i-pH yokwakheka inyuka nge-0.3 ukuya kwi-0.7 units kwiinyanga ezili-12, okwaneleyo ukutyhala i-formula ngaphezulu kwefestile ye-pH esebenzayo ye-active. Kwizinto ezisebenza ngokhathalelo lolusu kwi-pH engaphezulu kwe-9, kuquka ezinye ii-formula ezingasebenzi kakuhle ze-AHA kunye neefomathi ezithile ze-niacinamide, isizathu esifanayo siyasebenza.

I-USP <660> kunye ne-EP 3.2.1: Xa iGlasi yeBhotile kufuneka ivavanywe, ingabhengezwa nje kuphela

Umgangatho we-United States Pharmacopeia <660> kunye nomgangatho we-European Pharmacopoeia 3.2.1 zichaza uvavanyo lokumelana ne-hydrolytic kwizikhongozeli zeglasi. Le migangatho mibini ihambelana nendlela yokuvavanya kodwa yahlukile kwimfuno yovavanyo lomphezulu. I-USP <660> ifuna uvavanyo lomphezulu kuzo zonke izikhongozeli zeglasi ezihlelwe njengoHlobo I okanye uHlobo II, ngelixa i-EP 3.2.1 ifuna uvavanyo olukhulu kunye novavanyo lomphezulu kuzo zonke iintlobo zezikhongozeli.

Iglasi yeBorosilicate idibana ne-USP <660> Uhlobo I kwifomyula eqhelekileyo, akukho vavanyo lufunekayo kwinqanaba lebhetshi yemveliso. Isatifikethi sovavanyo sisibhengezo sexesha elinye ngomthengisi weglasi, asilulo uvavanyo lwebhetshi nganye. Iglasi yeSoda-lime idibana ne-USP <660> Uhlobo III kwifomyula eqhelekileyo, enesakhiwo esifanayo sesibhengezo sexesha elinye. Iglasi yeSoda-lime yohlobo lwe-II, enonyango lomphezulu ukunciphisa ukuvuza, ifuna uvavanyo lomphezulu ngebhetshi nganye ukugcina udidi lohlobo lwe-II.

Kwiimveliso zobuhle ezithengiswa njengokhathalelo lolusu okanye ubuhle, i-USP <660> kunye ne-EP 3.2.1 azifuneki ngokomthetho. Imigangatho iba yeyokusebenza xa imveliso yobuhle isenza ibango lesitayile seziyobisi, xa imveliso ithengiswa kwimarike esebenzise i-USP okanye i-EP alignment yezithambiso, okanye xa inkqubo yomgangatho wophawu ifuna umgangatho ofanayo wovavanyo njengomgca wamayeza. Kwibhrendi enovavanyo lwe-USP <660> kwifomyula, ibhotile kufuneka ibe yiType I okanye iType II kwinkqubo ye-USP, kwaye olo hlobo luqhuba ukhetho lweglasi.

Kwiimarike ezixabisa kakhulu apho imveliso yokuhombisa ingayibangi njengeyeza, iglasi ikhethwa kwifomyula kunye nomgca wokuzalisa endaweni yomgangatho we-USP. Umthetho we-European Union's cosmetic regulation 1223/2009 awufuni i-USP <660> yokupakishwa kokuhombisa, kwaye uninzi lweemarike ezingaphandle kwecandelo lokhathalelo lolusu elikufutshane namayeza zijonga ukhetho lweglasi njengesigqibo sophawu endaweni yesigqibo somthetho.

Kwiimpawu ezinebango lokhuseleko elishicilelweyo malunga nokukhuhla iglasi (umzekelo, "akukho kukhuhla kwiinyanga ezingama-24 kwi-pH 3.5″), ibango linokukhuseleka kwi-borosilicate kwaye alinakukhuseleka kwi-soda-lime. Ibango elifanayo lophawu kwi-soda-lime lingafuna unyango lomphezulu lubuyele kudidi lwe-Type II, okanye ibango lobomi beshelufu elivavanyiweyo elingaphantsi kophawu lweenyanga ezili-12. Sibona olu phawu lokutshintshiselana kwisigaba se-RFQ, apho abathengi abacela "ubomi beshelufu beenyanga ezingama-24 kwi-pH 3.5″ bakhokelwa kwi-borosilicate ngokungagqibekanga.

Idatha Yomzimba-Yoomatshini: Ubuninzi, Ukwanda, Ubulukhuni, kunye Nento Abayiqikelelayo Kumgca Wokuzalisa

Idatha ebonakalayo neyoomatshini ichaza ibali lento eya kunyanyekelwa yiglasi nganye kumgca wokuzalisa wokwenyani. I-Borosilicate inobunzima obumalunga ne-2.23 g/cm³, i-Young's modulus eyi-64 GPa, ubunzima be-Mohs obuyi-6.2, kunye ne-thermal conductivity eyi-1.2 W/(m·K). I-Soda-lime inobunzima obumalunga ne-2.52 g/cm³, i-Young's modulus eyi-72 GPa, ubunzima be-Mohs obuyi-6.0, kunye ne-thermal conductivity eyi-1.0 W/(m·K).

Ubunzima obuphantsi be-borosilicate buthetha ukuba ibhotile ye-30ml inobunzima obungaphantsi nge-12% kunobunzima be-soda-lime obufanayo ne-geometry efanayo. Ubunzima obuphantsi bukonga iindleko zokuthutha kwicala lomthengi kwaye konga iindleko zokuphatha kumgca wokuzalisa. I-modulus esezantsi ye-Young ithetha ukuba i-borosilicate iguquguquka ngakumbi xa itshayiswa, nto leyo ethetha ukuba izinga lokusinda eliphantsi kancinci kwiibhokisi zokuthumela liphezulu. Ukuqhuba okuphezulu kobushushu kuthetha ukuba i-borosilicate iphola ngokukhawuleza emva kokuzaliswa ngobushushu, nto leyo eyinzuzo yexesha lokujikeleza kumgca wokuzalisa.

Indlela eqhekeza iglasi phantsi koxinzelelo lobushushu kukwandiswa okuhlukeneyo kububanzi bodonga. Xa umphezulu wangaphakathi webhotile uphola ngokukhawuleza kunomphezulu wangaphandle, umphezulu wangaphakathi uyafinyela ngokukhawuleza kwaye ubeke umphezulu wangaphandle ekuxinaniseni. Iglasi ayisebenzi ekuxinaniseni okumalunga ne-30 ukuya kwi-50 MPa, kwaye ukwanda okuhlukileyo okuvelisa olo xinani kukubanjwa kwenombolo ye-ΔT.

I-borosilicate's coefficient yokwandisa ye-3.3 x 10^-6/K ithetha ukuba umahluko wobushushu be-1°C eludongeni uvelisa uxinzelelo olumalunga ne-0.0003%, oluyi-order of mass through. I-Soda-lime's coefficient ye-9 x 10^-6/K ithetha ukuba umahluko wobushushu be-1°C ofanayo uvelisa uxinzelelo olumalunga ne-0.0009%, olusondele kumda kwaye luchaza ukunyamezelana okuphantsi kakhulu kwe-ΔT. Umahluko woxinzelelo lobushushu ulinganiswa phantsi kwendlela yovavanyo loxinzelelo lobushushu oluqhelekileyo olusetyenziswa ngababoneleli abakhulu beglasi, oluvavanyo olufanayoidatha yothelekiso lobushushu beglasi ye-borosilicate vs soda-limeiireferensi ezithe kratya zedatha yophawu kunye nomthengisi.

Kumqhubi womgca wokugcwalisa, indawo yedatha efanelekileyo yi-ΔT esebenzayo ebonwa yibhotile ngexesha lokunikezelwa kwe-conveyor ebandayo. Ibhotile ye-borosilicate inokusinda kumahluko we-160°C kwilebhu, kodwa kumgca wokwenyani umahluko osebenzayo linani lelebhu elahlulwe yi-safety factor ye-2 ukuya kwi-3. Umahluko osebenzayo webhotile ye-soda-lime linani lelebhu elahlulwe yi-safety factor ye-3 ukuya kwi-5. Amanani azisa ukujonga umgca wemihla ngemihla: ukuba umgca uhambisa iibhotile kwi-50°C ukuya kwi-20°C conveyor, ibhotile ye-soda-lime ikwi-30°C yomda osebenzayo, ngelixa ibhotile ye-borosilicate ikwi-60°C ukuya kwi-70°C yomda osebenzayo.

Apho iSoda-Lime Iphumelela khona: Ixabiso, Ukucaca Okubonakalayo, kunye Nokwakheka Koomatshini

Iglasi yesoda-lime yeyona ifanelekileyo kwiibhotile ezininzi zokuhombisa, kwaye ukhetho olufanelekileyo alunanto yakwenza nexabiso eliphantsi. Iimpawu ezintathu ezenza i-soda-lime ibe yimigangatho ziindleko, ukucaca kokukhanya, kunye nobuchule bokubumba.

Ngokuphathelele ixabiso, i-soda-lime itshiphu ngama-30% ukuya kuma-60% ngebhotile kune-borosilicate kwi-geometry efanayo. Umahluko weendleko ubangelwa lixabiso lezinto eziluhlaza ze-boron trioxide kunye nobushushu obuphezulu besithando esifunekayo ukunyibilikisa i-borosilicate. Kwibhrendi esebenzisa iibhotile ezili-100,000 ngenyanga, umahluko weendleko zonyaka unentsingiselo kwaye ubonakala ngqo kumgca we-margin. Kwibhrendi esebenzisa iibhotile ezizigidi ezi-1 ngenyanga, umahluko weendleko ngumahluko phakathi kwe-SKU esebenzayo kunye ne-SKU eyeka ukusebenza kunyaka wesibini. Uthelekiso lweendleko luxhaswa yi-cullet stream economics epapashwe yi-IZiko lokuPakisha iGlasi (i-GPI), elandelela umahluko wamaxabiso omxholo ophinda usetyenziswe phakathi kweentsapho ezimbini zeglasi unyaka nonyaka.Isakhelo se-EU sommiselo wezinto zokuthambisa 1223/2009ilawula ukusebenziseka kwakhona kunye nokuthobela ukupakishwa kweentsapho zombini zeglasi kwimarike yaseYurophu.

Xa kujongwa ukucaca kwe-optical, i-soda-lime yeyona glasi icacileyo. I-refractive index yi-1.518, eyimigangatho yokupakisha iglasi yokuhombisa. I-Borosilicate ine-refractive index eyi-1.474, engacacanga kangako kwaye yahlukile kancinci kwindlela ukukhanya okudlula ngayo ebhotileni. Kwigama apho ukucaca kwebhotile kuyibango eliphambili lokuthengisa, i-soda-lime yeyona glasi ibukeka intle.

Xa i-mechanical formability, i-soda-lime inokubunjwa ibe luluhlu olubanzi lweejiyometri ngesantya esiphezulu semveliso. Indawo yokunyibilika iphantsi, uluhlu lokusebenza lubanzi, kwaye iglasi inokuvuthelwa, icinezelwe, kwaye icinezelwe kwaye ivuthelwe kwizixhobo eziqhelekileyo zeebhotile zezithambiso. I-Borosilicate ifuna uluhlu lokusebenza oluqinileyo kunye nokupholisa okulawulwayo ngakumbi, oku kuthintela ukhetho lwejiyometri kwaye kunciphisa izinga lemveliso. Kwi-brand enejiyometri eyenzelwe wena, i-soda-lime yeyona glasi isebenzisekayo ngakumbi ukuyichaza. Iinketho zejiyometri zeebhotile zezithambiso eziqhelekileyo zidweliswe phantsi kwe-Imigangatho yokugqiba iibhotile ze-SPI (Society of the Plastics Industry)kubhekiswa kuzo ziivenkile ezininzi ze-mold ezenziwe ngokwezifiso xa kucetywa ukuba kunokwenzeka ukwenza i-geometry kwi-SKU entsha.

Kwicala lempahla yokugcina impahla kunye nokuthunyelwa kwayo, inzuzo ye-soda-lime ibalulekile. Sipakisha iibhotile ze-soda-lime kwi-corrugated eqhelekileyo eneendonga ezimbini kunye nenani lokwahlulahlula eliyi-12 ukuya kwi-24 ngebhokisi nganye kuxhomekeke kwi-geometry yebhotile, kwaye i-case ithunyelwa kwiklasi ye-truck freight class. Sipakisha iibhotile ze-borosilicate kwibhokisi efanayo kodwa inani lokwahlulahlula lincitshiswe malunga ne-15% ukuze kujongwe iindleko eziphezulu zokwaphuka kwayo. Ikhefu lokuthutha elibiza umthengi iisenti ezingama-50 ngebhotile ye-soda-lime libiza iisenti ezingama-80 ukuya kwidola enye ngebhotile ye-borosilicate, kwaye loo mahluko womngcipheko yiloo nto siyiqwalaselayo kwiinkcukacha zokupakisha zokuthunyelwa kwethu kwamanye amazwe.

Apho iBorosilicate iphumelela khona: Ukumelana nobushushu, ukumelana ne-asidi, kunye nobomi obude beshelufu

Iglasi yeBorosilicate yeyona ndlela ifanelekileyo yokusebenzisa apho umxube okanye umgca wokuzalisa ugxininisa ibhotile ngaphaya kwamandla e-soda-lime. Iimpawu ezintathu ezenza i-borosilicate ibe yinkcazo yeprimiyamu kukumelana nobushushu, ukumelana ne-asidi, kunye nobomi obude beshelufu.

Xa i-borosilicate imelana nobushushu, ingaphila i-hot-fill engaphezulu kwama-80°C kwaye ingafakwa i-autoclave kwi-121°C ukuze ibulawe iintsholongwane. Ubuchule be-autoclave yimbangela yokuba i-borosilicate ibe ngumgangatho wamayeza kwiimveliso ezifakwa kwi-injection, kwaye ubuchule obufanayo benza i-borosilicate ibe ngumgangatho weemveliso zokhathalelo lolusu ezifuna i-sterilizer fill. Kwi-brand enebango "elingenazo izithinteli", i-sterilizer fill idla ngokufumaneka ngokubulala iintsholongwane kwibhotile ezaliswe yi-autoclave, enokufezekiswa kuphela kwi-borosilicate.

Xa i-asidi ixhathisa, i-borosilicate ibamba i-pH yokwakheka kuyo yonke i-pH 2 ukuya kwi-pH 11, ngaphandle kotshintsho olulinganisekayo kwiinyanga ezili-12 kwi-40°C. Ukumelana ne-asidi yimbangela yokuba i-borosilicate ibe ngumgangatho weefomyula ze-AHA, iifomyula ze-salicylic acid, kunye nee-oyile ezixutyiweyo ezine-citral essential. Kwi-brand ene-pH-sensitive esebenzayo, i-borosilicate yeyona nkcazelo ikhuselekileyo kuphela.

Xa i-borosilicate ihlala ixesha elide, igcina iipropati zayo ixesha elide kuneenyanga ezingama-36 ngaphandle kotshintsho olulinganiswayo, ngelixa i-soda-lime idla ngokubonisa utshintsho olulinganiswayo emva kweenyanga ezili-18 kuluhlu lwe-pH 2 ukuya kwi-pH 4.
