Ingilazi ye-borosilicate ephezulu uhlobo olukhethekile lwengilazi olwaziwa ngezakhiwo zalo ezihlukile, ikakhulukazi esimweni sokumelana nokushisa kanye namandla omshini. Ibhekwa njengengcono kunengilazi evamile ezisetshenziswayo ezahlukahlukene, kusukela emishinini yelabhorethri kuya ezitsheni zokupheka ezisezingeni eliphezulu. Ngezansi, sihlola ngokujulile umehluko oyinhloko phakathi kwengilazi ye-borosilicate ephezulu nengilazi evamile, sichaza ukuthi kungani iyinto ethandwayo ezimbonini ezithile.
1. Isilinganiso Sokwanda Kokushisa
I-coefficient of thermal expansion (CTE) iyisilinganiso sokuthi into ikhula noma incipha kangakanani lapho izinga lokushisa layo lishintsha. Lesi sici sibalulekile ekusetshenzisweni lapho izinto zibhekana nokushintshashintsha okukhulu kwezinga lokushisa.
- Ingilazi Ephakeme Ye-Borosilicate: Esinye sezici ezivelele zengilazi ye-borosilicate ephezulu yi-coefficient yayo ephansi yokwanda kokushisa. Cishe ingxenye eyodwa kwezintathu zengilazi evamile, okusho ukuthi iyakhula futhi inciphe kancane kakhulu uma ivezwa izinguquko zokushisa. Lokhu kunciphisa kakhulu ingozi yokuqhekeka noma yokuphuka ngenxa yokucindezeleka kokushisa. Ngenxa yalokho, ingilazi ye-borosilicate ephezulu imelana kakhulu nokushaqeka kokushisa, okwenza ifaneleke kakhulu ekusetshenzisweni okufana nezitsha zeglasi zelebhu, izimbiza zokupheka, kanye nama-beakers avame ukubhekana nokushintsha kwezinga lokushisa okungazelelwe.
- Ingilazi Ejwayelekile: Ingilazi evamile inesilinganiso esiphakeme kakhulu sokwanda kokushisa. Ngenxa yalokho, isengozini enkulu yokucindezeleka ngenxa yokushintsha kwezinga lokushisa okusheshayo. Isibonelo, lapho ingilazi evamile ishiswa noma ipholiswa ngokushesha, izinto ziyanda noma zincipha kakhulu, okudala ukucindezeleka okungaholela ekuqhekekeni noma ngisho nokwehluleka ngokuphelele. Yingakho ingilazi evamile ngokuvamile inganconywa ukusetshenziswa lapho ukumelana nokushaqeka kokushisa kubalulekile khona.
2. Izingxenye Eziyinhloko
Ukwakheka kwengilazi kudlala indima ebalulekile ekunqumeni izakhiwo zayo zomzimba nezamakhemikhali. Ingilazi ye-borosilicate ephezulu yenzelwe ukunikeza amandla aphezulu kanye nokumelana nokucindezeleka kokushisa kanye namakhemikhali.
- Ingilazi Ephakeme Ye-Borosilicate: Lolu hlobo lwengilazi luqukethe ngokuyinhloko i-boron trioxide (kufika ku-14%) kanye ne-silicon dioxide (kufika ku-80%). Ukufakwa kwe-boron kuthuthukisa ukumelana kwengilazi nokushaqeka kokushisa, njengoba ama-athomu e-boron esiza ekunciphiseni ukwanda kwengilazi ngesikhathi sokushisa nokupholisa. Ngaphezu kwalokho, ukwakheka kwamakhemikhali kwengilazi ye-borosilicate kuyinika ukumelana okuhle kakhulu namakhemikhali ahlukahlukene, ama-asidi, nama-alkali, okwenza ifaneleke ukusetshenziswa emalabhorethri nasezimbonini lapho ukuchayeka kumakhemikhali anamandla kuvame khona.
- Ingilazi Ejwayelekile: Ingilazi evamile yenziwe ngokuyinhloko nge-sodium calcium silicate, kanye ne-silica (SiO2) njengengxenye eyinhloko. Ukwakheka kwengilazi evamile akubandakanyi i-boron, enciphisa ikhono layo lokubekezelela ukucindezeleka kokushisa kanye nezimo zamakhemikhali ezinzima. Nakuba ifaneleka ukusetshenziswa okuvamile njengamafasitela namabhodlela, ayinazo izakhiwo ezithuthukisiwe ezidingekayo ekusetshenzisweni okunzima kakhulu.
3. Amandla Okudonsa
Amandla okudonseka abhekisela ekhonweni lento yokumamela amandla okudonsa noma okwelula. Izibuko ezinamandla okudonseka aphezulu zingabekezelela amandla amaningi ngaphambi kokuba ziqhekeke noma ziphuke.
- Ingilazi Ephakeme Ye-Borosilicate: Ingilazi ye-borosilicate ephezulu inamandla okubamba aphezulu kakhulu kunengilazi evamile. Lokhu kusho ukuthi ingamelana nokucindezeleka okukhulu komshini ngaphandle kokuphuka. Lapho ingilazi ye-borosilicate ephezulu iphuka, ivame ukuphuka ibe yizicucu ezinkulu, ezifana neyunithi kunokuba iqhekeke ibe yizicucu ezibukhali neziyingozi. Lokhu kwenza kube kuphephile ukuyiphatha ezindaweni lapho ukuphuka kungaba yingozi khona.
- Ingilazi Ejwayelekile: Ingilazi evamile inamandla aphansi okubamba, okwenza ibe sengozini yokuphuka ngaphansi kokucindezeleka. Uma iphuka, ingilazi evamile ivame ukuphuka ibe yizicucu ezincane, ezigobile, okungadala izingozi zokuphepha. Lesi esinye sezizathu ezenza ingilazi evamile igwenywe ngokuvamile ezisetshenziswayo lapho kusetshenziswa ukucindezeleka okukhulu noma lapho nomthelela omkhulu.
4. Ukumelana Nokushaqeka Okushisayo
Ukumelana nokushaqeka kokushisa yikhono lento yokubekezelela izinguquko zokushisa okusheshayo ngaphandle kokuqhekeka noma ukuphuka. Lesi sici sibaluleke kakhulu ezintweni ezisetshenziswa ekuphekeni, ezindaweni zelebhu, kanye nezinqubo ezithile zezimboni.
- Ingilazi Ephakeme Ye-Borosilicate: Enye yezinzuzo eziyinhloko zengilazi ye-borosilicate ephezulu ukumelana kwayo okumangalisayo nokushaqeka kokushisa. Ingamelana nokushintsha kwezinga lokushisa okukhulu nokusheshayo ngaphandle kokuqhekeka. Isibonelo, ingabekezelela ukungezwa kwamanzi abilayo (100°C) engilazini ngisho noma ibekwe endaweni ebandayo (-30°C). Lokhu kwenza kube ukukhetha okuhle kakhulu kwezitsha zokupheka (njengezitsha zokubhaka zengilazi), imishini yelabhorethri, kanye nezinye izinhlelo zokusebenza lapho kuvamile khona ukushintsha kwezinga lokushisa.
- Ingilazi Ejwayelekile: Ingilazi evamile, ngakolunye uhlangothi, isengozini enkulu yokushaqeka kokushisa. Uma ibhekene nokushintsha kwezinga lokushisa okungazelelwe, kungenzeka ukuthi iqhekeke noma iqhekeke ngenxa yokwanda noma ukufinyela okusheshayo kwezinto. Yingakho izitsha zengilazi ezivamile kungafanele neze zivezwe emanzini abilayo noma zibekwe ngqo endaweni ebandayo ziye endaweni eshisayo.
Ukusetshenziswa Kwengilazi Ephakeme Ye-Borosilicate
Njengoba inezici zayo ezinhle kakhulu, ingilazi ye-borosilicate ephezulu isetshenziswa ezinhlobonhlobo zezicelo ezidinga ukusebenza okuphezulu, ukuphepha, kanye nokuqina:
- Izingilazi Zelebhu: Ngenxa yokumelana kwayo nokushaqeka kokushisa kanye nokugqwala kwamakhemikhali, ingilazi ephezulu ye-borosilicate ivame ukusetshenziswa emalabhorethri enziwe ngama-beakers, amaflask, amashubhu okuhlola, kanye neminye imishini edinga ukumelana nokushisa kanye namakhemikhali.
- Izitsha zokupheka: Ingilazi ye-borosilicate ephezulu isetshenziswa kakhulu ezitsheni zasekhishini njengezitsha zokubhaka, izinkomishi zokulinganisa, kanye nezitsha zokupheka, lapho ukumelana kwayo nokushisa kanye nokushaqeka kokushisa kuyinzuzo ebalulekile.
- Izinsimbi Zokubona: Ukucaca okuphezulu kokukhanya kwengilazi ye-borosilicate kwenza ifaneleke kumalensi nakwamanye amadivayisi okukhanya.
- Ukukhanyisa kanye ne-elekthronikhi: Ingilazi ye-borosilicate ephezulu isetshenziswa ekukhanyeni okuthile kanye nezingxenye ze-elekthronikhi, lapho ukuqina kwayo kanye nokumelana nokushisa kubalulekile khona.
Isiphetho
Ingilazi ye-borosilicate ephezulu iyinto ethuthukisiwe ehamba phambili ekusetshenzisweni okudinga ukumelana nokushisa, ukucindezeleka komshini, kanye nokuchayeka kwamakhemikhali. Ukwanda kwayo okuphansi kokushisa, amandla aphezulu okudonseka, kanye nokumelana okungavamile nokushaqeka kokushisa kuyenza ibe ngcono kunengilazi evamile ekusetshenzisweni okudingakalayo emikhakheni efana nomsebenzi welabhorethri, ukupheka, kanye nezinqubo zezimboni. Nakuba ingilazi evamile ifanelekela izinjongo ezijwayelekile, izakhiwo ezihlukile zengilazi ye-borosilicate ephezulu ziqinisekisa ukuthi ihlala iyimpahla ekhethwayo ekusetshenzisweni okukhethekile lapho ukusebenza nokuphepha kubaluleke kakhulu.
