Babban tubalin alumina narkewa aya

Babban tubalin alumina wani nau’i ne na bulo mai jujjuyawa. Dangane da abun ciki na alumina, babban bulo na alumina ya kasu kashi na musamman bulo na alumina, bulo na firamare, na sakandare da na uku. Abubuwan da ke cikin alumina na manyan tubalin alumina uku sun bambanta. Mafi girman abun ciki na aluminum, ƙarancin sauran ƙazanta, ƙarancin jikin gilashin da ke da sauƙin narkewa, da yanayin zafi daban-daban a ƙarƙashin kaya.

1. Babban tubalin alumina na musamman: abun cikin alumina ya fi 80% girma, kuma nauyin taushin zafin jiki yana kusan 1550 ° C.

2. Farko grade high alumina tubali: The alumina abun ciki ne mafi girma fiye da 75%, da load softening zafin jiki ne game da 1510 ℃.

3. Secondary high alumina tubali: The alumina abun ciki ne mafi girma fiye da 65%, da kuma lodi softening zafin jiki ne game da 1460 ℃.

4. Uku-matakin high-alumina tubali: abun ciki na aluminum ne fiye da 55%, da softening zafin jiki a karkashin kaya ne game da 1420 ℃.
