Ukukhetha ubumba lwe-kaolin olufanele kudinga ukucabangela izici ezilandelayo:
1. Usayizi wezinhlayiyana: Ngokwezidingo zakho, khetha usayizi wezinhlayiyana ezifanele. Ngokuvamile, i-kaolin enezinhlayiya ezicolekile ifaneleka ukukhiqizwa kwemisebenzi yezandla ethambile efana ne-ceramics ne-coatings, kuyilapho i-kaolin enezinhlayiya ezimahhadla ifanele ukukhiqizwa kwezitini zobumba, amapayipi e-ceramic nezinye izinto zokwakha.
2. Ukungcola: Ukungcola kwe-kaolin kuzothinta ukusebenza kwayo, ngakho-ke kuyadingeka ukukhetha i-kaolin enokungcola okuncane. Ngokuvamile, i-kaolin ehlanzekile ifanele ukukhiqizwa kwemikhiqizo ye-ceramic yekhwalithi ephezulu.
3. Ukwakheka kwamaminerali: I-kaolin ehlukene iqukethe ukwakheka kwamaminerali ahlukene, okuzothinta ukusebenza kwayo kwe-sintering, ipulasitiki nezinye izici. Ngokwezidingo ezithile zenqubo, i-kaolin equkethe ukwakheka kwamaminerali afanelekile kuyakhethwa.
4. Imvelaphi kanye nesithunzi somphakeli: khetha abahlinzeki abathembekile ukuze uqinisekise ikhwalithi nokuzinza kwe-kaolin.
Uma kucatshangelwa lezi zici ezingenhla, ubumba lwe-kaolin olufanele lungakhethwa ukuze kukhiqizwe inqubo ethile.
