Ngabe ingilazi ye-borosilucate ingcono kunengilazi ejwayelekile?

Ingilazi ye-borosilate ithole ukunakwa ukuphakama kwayo okuhlangene ngaphezulu kwengilazi ejwayelekile ekuphangethweni kwezimonyo kanye nezinye izinhlelo eziningi. Kepha kungcono ngempela?

Kulesi sihloko, singena ezingxenyeni, izici, izinzuzo phezu kwengilazi ejwayelekile, nezinhlobo ezahlukene zengilazi ye-borossilte ukunikeza ukucaca ngale ndaba.

Yini ingilazi ye-borossilte?

Ingilazi ye-borosilicate yenziwa kusuka kuzithako ezi-2 eziphambili: silica ne-boron. Iphuzu likaSelica likaSebilita liphezulu kakhulu (1730 ° C), ukwenza lokhu kucutshungulwa kumazinga aphansi ngakho-ke longa amandla, ezinye izakhi ezibizwa nge-fluxes ziyangezwa. Futhi, abanye abaqiniswayo (i-alkaline oxides, i-alumina, kanye ne-alkalina oxide) yengezwa ukuqinisa ingilazi, enikeza izakhiwo ezinhle kakhulu.

Ukumelana Kakhulu Kwamakhemikhali: Ukuqina Okuphezulu Kwamakhemikhali Nokuqina Ezindaweni Ezihlanzekile.
Ukumelana nokushisa okuphezulu: ukumelana okuhle kakhulu kokushaqeka okushisayo kanye nama-gradients ashisayo, kanye nokunwebeka okuphansi okushisayo.
Amandla amahle emishini: Ukugqoka kakhulu- futhi akwazi ukumelana, namandla avumelanayo aguqukayo kanye nekhono lokumelana nemithwalo emishini efunwayo.
Ukucaca okuphezulu: Kuqinisekisa ukucaciseleka okuhle nokuhlanekezela ukukhanya okulula ngaphezulu kobubanzi obubanzi obubanzi.
Izinhlobo zeglasi le-borosilucate ingilazi

borosilicate ingilazi iza ngezinhlobo ezahlukahlukene ngokuya ngokuqukethwe kwe-boron oxide, okuthinta izakhiwo zalo. Lezi zinhlobo zifaka:

Ingilazi ephansi ye-borosiliLing: lolu hlobo luqukethe amaphesenti aphansi eBoron oxide, ngokujwayelekile kusuka ku-5% kuya ku-10%. Inikeza ukumelana okulinganiselayo kokushibilika futhi isetshenziswa kakhulu ezintweni zasendlini njenge-cookware ne-typware.
Ingilazi ephakathi nendawo: Ngokuqukethwe kwe-boron oxide kusuka ku-10% kuya ku-13%, ingilazi ye-maidy borosilucate inikezela ukumelana okuthuthukile okuthuthukile ngokuqhathaniswa nokuhluka okuphansi kwe-borosiling. Ithola izinhlelo zokusebenza emishini yelebhu kanye nezilungiselelo zezimboni lapho kudalwa khona ukuqina okuphezulu.
Ingilazi ephezulu ye-borosilicate: Ingilazi ephezulu ye-borosilile iqukethe amaphesenti aphezulu kakhulu eBoron oxide, imvamisa edlula i-13%. Lolu hlobo luqhayisa ukumelana nokuqina okuphezulu okushisayo nokuqina kwamakhemikhali, okwenza kube lula ukuthola izinhlelo zokusebenza ezifana ne-langorare glarsware kanye ne-opics ephezulu.
Isiphetho

Ekuphetheni, ingilazi ye-borossilland inikeza izinzuzo eziningana ngengilazi ejwayelekile, kufaka phakathi ukushaqeka okuphezulu nokuphikiswa kwamakhemikhali, kanye nokuqina okuthuthukile. Ngenkathi ingilazi ye-borosilile ingafika ngezindleko eziphakeme, ukusebenza kwayo okuhlukile nokuphila isikhathi eside kuvame ukucacisa ukutshalwa kwemali, ikakhulukazi ekuphangethweni kwezimonyo.
