Faka i-vermiculite
I-Vermiculite isetshenziselwa ukuchamisela amaqanda, ikakhulukazi amaqanda ezilwane ezihuquzelayo.Amaqanda ezilwane ezihuquzelayo ezihlukahlukene, okuhlanganisa izigcilikisha, izinyoka, izibankwa nezimfudu, angachanyuselwa ku-vermiculite eyandisiwe, okufanele ifakwe emanzini ezimweni eziningi ukuze kugcinwe umswakama.Bese kwakheka ukucindezeleka ku-vermiculite, enkulu ngokwanele ukubeka amaqanda ezilwane ezihuquzelayo nokuqinisekisa ukuthi iqanda ngalinye linendawo eyanele yokuchamisela.

Ibhodi le-Vermiculitse
Ibhodi le-Vermiculite wuhlobo olusha lwezinto ezingaphili, ezisebenzisa i-vermiculite enwetshiwe njengento eluhlaza eyinhloko, ixutshwe nengxenye ethile ye-inorganic binder, futhi icutshungulwa ngochungechunge lwezinqubo.Inokumelana nokushisa okuphezulu, ukuvikelwa komlilo, ukuvikelwa kwemvelo okuluhlaza, ukufakwa kokushisa, ukufakwa komsindo, Amapuleti aqukethe izinto eziyingozi.Ayishi, ayincibiliki, futhi imelana nezinga lokushisa eliphezulu.Ngenxa yokuthi ibhodi le-vermiculite lisebenzisa i-vermiculite enwetshiwe njengento eluhlaza eyinhloko, izinto ezingaphili azinayo i-carbon element futhi azishi.Iphuzu layo lokuncibilika liyi-1370 ~ 1400 ℃, izinga lokushisa eliphezulu lokusebenza ngu-1200 ℃.
