Imindeni Emibili Yengilazi: I-Borosilicate kanye ne-Soda-Lime Eceleni

Ingilazi ye-borosilicate yakhiwe nge-silica ne-boron trioxide, okuqukethwe yi-B2O3 cishe ku-12% kuya ku-15% wefomula. I-boron ithatha indawo yama-sodium ne-calcium oxides akha ingilazi ye-soda-lime, futhi lokho kushintshana okukodwa yikho okuqhuba cishe wonke umehluko wesakhiwo esingezansi. Izinga lokushisa lokushintsha kwengilazi liphakeme, ukwanda kokushisa cishe kuyingxenye yesithathu, kanti ukuqina kwamakhemikhali ngokumelene namanzi nezixazululo ze-asidi kuphindwe kaningana.

Ingilazi ye-soda-lime iyindlela yokusebenza embonini yokupakisha izimonyo. Le fomula cishe ingu-70% we-silica, u-15% we-sodium oxide, u-9% we-calcium oxide, kanye ne-magnesium, i-aluminium, kanye nezakhi zokulandelela ezilinganayo. Kushibhile ukuyikhiqiza, kulula ukuyibumba ibe yizinhlobonhlobo zamajiyometri amabhodlela ezimonyo emakethe ayilindele, futhi ingaphinde isetshenziswe ngokugcwele ngokusebenzisa umfudlana omkhulu we-cullet. Izakhiwo ezifanayo ezenza i-soda-lime ishibhile futhi isebenze kahle nazo zenza kube sengozini yokushaqeka kokushisa kanye nokuphuma kwe-alkaline ngaphansi kwezimo ze-asidi.

Amaqiniso amathathu okwakheka aqhuba cishe yonke imininingwane kulokhu kuqhathanisa. Okokuqala, i-boron ku-borosilicate iyi-grill network yangaphambili, okusho ukuthi ibopha ngqo ku-silica lattice futhi ikhiqize isakhiwo esiqinile nesiqinile kakhulu. Okwesibili, i-sodium ku-soda-lime iyi-network modifier, okusho ukuthi ihlala ezikhaleni ze-silica lattice futhi iphuma lapho ivezwa emanzini noma ezixazululweni ze-acidic. Okwesithathu, ukungabikho kwe-boron ku-soda-lime yikho okuvumela ukwakheka ukuthi kulungiselelwe ukucaca nokwakheka kunokuba kube ukumelana nokushisa noma amakhemikhali.

Emgqeni wokukhiqiza, umehluko phakathi kwemindeni emibili yengilazi ubonakala emisebenzini emithathu. Sihlola i-cullet ngaphambi kokulayisha inqwaba ukuze sigcine umbala kanye ne-coefficient yokwanda ngaphakathi kwebhendi ecacisiwe yomhlinzeki. Silinganisa i-coefficient yokwanda kokushisa kusampula ekhishwe kusuka ekugijimeni kwesithando ngasinye, futhi senqaba noma yiliphi isampula elikhukhuleka ngaphezu kuka-0.2 x 10^-6/K kusuka enanini elimenyezelwe lomhlinzeki. Sihlola ukujiya kodonga lwebhodlela ngemva kokwakheka, ngoba ukujiya kodonga yikho okunquma ukubekezelelana kwangempela kwe-ΔT emgqeni wokugcwalisa ngaphezu komndeni weglasi uqobo.

Ibhodlela le-soda-lime liyahluleka ngesilinganiso sokwenqatshwa esingu-2% kuya ku-5% ekuqaleni kokuqala futhi liwohloka njengoba umugqa ufudumala. Umehluko ongu-2% kuya ku-5% umehluko phakathi komugqa wokugcwalisa osebenzayo kanye nomugqa odonswa emuva kumhlinzeki wamabhodlela ukuze kuphenywe imbangela.

Kumugqa ojwayelekile wokugcoba obandayo osebenza kuma-degree Celsius angama-22 kanti owehlayo ungama-degree Celsius ayi-18, umehluko ungama-degree Celsius ama-4. Yomibili imindeni yengilazi idlula lolu shintsho ngaphandle kwesilinganiso sokwenqatshwa esilinganiswayo. I-premium ye-borosilicate ayifaneleki emigqeni yokugcwalisa obandayo, futhi izindleko ezengeziwe zibonakala njengokunciphisa okuqondile kwe-margin ngaphandle kokuzuza kokuthembeka komugqa wokugcwalisa okuhambisanayo.

Umehluko wokushaqeka kokushisa ubalulekile nakumthengi. Ibhodlela le-borosilicate lingasuka endlini yokugezela eshisayo kuma-degree Celsius angu-38 liye esiqandisini kuma-degree Celsius angu-4 ngaphandle kokuqhekeka, yingakho i-borosilicate iyindinganiso yama-serum agcwalisayo athengiswa ezindaweni lapho kulindeleke ukuthi umthengi agcwalise khona ngemva kokuvula. Ibhodlela le-soda-lime lingasuka eshalofini lama-degree Celsius angu-30 liye esiqandisini sama-degree Celsius angu-4, kodwa alikwazi ukusuka e-hot-fill reject engu-60 degrees Celsius liye e-wash-down engama-degree Celsius angu-20 ngaphandle kokusikwa.

Ngefomethi yebhodlela le-dropper elingu-30ml, imfuneko ewusizo ukuthi ibhodlela lisinde ekwehleni kwezinga lokushisa lokugcwalisa elingu-50 degrees Celsius liye ku-conveyor yokupholisa engu-25 degrees Celsius. Yomibili imindeni yengilazi idlula lolu shintsho, kodwa ibhodlela le-soda-lime libamba umkhawulo omncane wokushisa futhi lizwela kakhulu ekumisweni komugqa lapho ingxenye eshisayo yokugcwalisa iphola khona ngenkathi amabhodlela eqhubeka nokudla. Ukuma komugqa wemizuzu eyi-10 ku-50 degrees Celsius nge-soda-lime kuveza izinga lokwenqatshwa elilinganiswayo ku-conveyor elandelayo ebandayo; ukuma komugqa ofanayo ne-borosilicate akubonakali kukhawunta yokwenqatshwa.

Idatha Yokuhambisana Kwamakhemikhali: i-pH 2 kuya ku-pH 11 Kuzo Zonke Izakhi Zotshwala, Uwoyela, kanye Namanzi

Ukuhambisana kwamakhemikhali yilapho imindeni emibili yengilazi ihlukana khona kakhulu. I-Borosilicate ekilasini le-hydrolytic HGA 1 ayibonisi ukwehla kwesisindo okulinganiselwe, akukho ukushintsha kwe-pH okulinganiselwe, futhi akukho ukuhlaselwa komhlaba okulinganiselwe kulo lonke uhla lwe-pH 2 kuya ku-pH 11 ngaphansi kokuguga okusheshayo kuma-degree Celsius angu-40 izinyanga ezingu-12. I-Soda-lime ekilasini le-hydrolytic HGB 3 ayibonisi ukuhlaselwa okulinganiselwe ebangeni le-pH 5 kuya ku-pH 8, kodwa ukuhlaselwa okulinganiselwe ku-pH 2 kuya ku-pH 4 kanye ne-pH 9 kuya ku-pH 11.

Indlela yokuhlasela ku-soda-lime iqondwa kahle. Ama-ion e-sodium ku-lattice ye-silica ashintshana nama-ion e-hydrogen ku-formulation, akhuphule i-pH yokwakheka futhi adale ungqimba oluncane olune-leached ebusweni bangaphakathi bebhodlela. Izinga lokukhipha licishe libe ngama-micrometer angu-0.1 kuya ku-0.3 ngonyaka ku-pH 7, kodwa lishesha libe ngama-micrometer angu-1 kuya kwangu-3 ngonyaka ku-pH 3 noma ku-pH 10. Ungqimba olune-leached luncane ngokwanele ukuba lungabonakali futhi lube lukhulu ngokwanele ukuphazamisa izinto ezithinta i-pH.

Kuma-formula asekelwe ku-alcohol anokuqukethwe kwe-ethanol okungaphezu kuka-20%, yomibili imindeni yengilazi ayibonisi ukuhlaselwa okulinganiselwe. Utshwala luyisithako esivikela ingilazi ekwakhiweni ngoba lunciphisa ukusabela kokushintshana kwama-ion. Kuma-formula asekelwe ku-oyela kufaka phakathi ukuxubana kwamafutha abalulekile, yomibili imindeni yengilazi ayibonisi ukuhlaselwa okulinganiselwe kulo lonke uhla lwe-pH; uwoyela awushintshisani ama-ion nge-lattice ye-silica. Sihlola i-matrix yokuhambisana kwamakhemikhali ngokumelene ne-idatha yereferensi yokuhambisana kwamakhemikhali e-borosilicate vs soda-limenjengesisekelo, ngoba idatha yokuhambisana kwamakhemikhali eshicilelwe ibamba isimo esibi kakhulu semithi futhi noma yikuphi ukupakishwa kwezimonyo okudlula izimo ezifanayo zokuhlola kudlula ukuhlolwa kokulawula izimonyo ngokuzenzakalelayo.

Umphumela osebenzayo wokuhlanganiswa kwamafutha abalulekile ukuthi ukukhetha ingilazi kuqhutshwa yi-chemistry yamafutha abalulekile kunebhodlela. Amafutha e-citrus anokuqukethwe okuphezulu kwe-citral, amafutha e-clove anokuqukethwe okuphezulu kwe-eugenol, kanye namafutha e-sinamoni anokuqukethwe okuphezulu kwe-cinnamaldehyde konke kuyi-acid emnene futhi kuzosheshisa ukugeleza kwe-soda-lime. Ebhodleleni lamafutha abalulekile elingu-30ml elenzelwe ukuhlanganiswa kwe-citrus, uhlobo lwe-borosilicate luyindlela ephephile yokucacisa. Ebhodleleni lamafutha elithwala elingu-30ml elingenazo izinto ezivuselelayo, i-soda-lime ilungile.

Kuma-actives okunakekela isikhumba ku-pH engaphansi kuka-4, kufaka phakathi i-glycolic acid, i-lactic acid, i-salicylic acid, kanye ne-ascorbic acid formulations, incazelo ye-borosilicate iyindinganiso. Isikhathi sokuphila kweshelufu sezinyanga ezingu-24 ku-pH 3.5 asitholakali ku-soda-lime ngoba i-pH yokwakheka ikhuphuka ngamayunithi angu-0.3 kuya ku-0.7 ezinyangeni ezingu-12, okwanele ukusunduza ukwakheka ngaphezu kwefasitela le-pH elisebenzayo le-active. Kuma-actives okunakekela isikhumba ku-pH engaphezu kuka-9, kufaka phakathi amanye ama-formula angenawo amandla e-AHA kanye namafomethi athile e-niacinamide, ukucabanga okufanayo kuyasebenza.
