2) Hom silicon hlau los ntawm lub cev daim ntawv (zoo li thiab loj)
Tshaj li qib, silicon hlau kuj raug cais los ntawmdaim ntawv lub cev, uas cuam tshuam ncaj qha rau kev tuav, cov tshuaj tiv thaiv ceev, thiab tus nqi rov qab.
A) Silicon Hlau Lumps
Silicon hlau lumpsyog cov ntawv tshaj plaws hauv kev lag luam thoob ntiaj teb. Lawv yog tsim los ntawm crushing thiab tshuaj xyuas silicon hlau ingots rau hauv kev tswj qhov loj me.
Cov yam ntxwv tseem ceeb:
- khoom pob daim ntawv
- muaj nyob rau hauv ntau qhov ntau thiab tsawg
- yooj yim los tuav thiab thauj
Tej kev siv:
- aluminium alloy ntau lawm
- metallurgical rauv
- bulk industrial siv
Rau cov nroj tsuag txhuas thiab cov neeg siv hlau metallurgical, silicon lumps nyiam dua vim tias lawv muaj kev noj zaub mov ruaj khov thiab cov yam ntxwv uas tuaj yeem ua tiav.
B) Silicon hlau hmoov
Silicon hlau hmoovyog tsim los ntawm kev crushing ntxiv thiab milling silicon hlau lumps rau hauv cov khoom zoo nrog kev tswj mesh qhov ntau thiab tsawg.
Cov yam ntxwv tseem ceeb:
