LAWV
CHM 08A tuaj yeem siv tau rau tooj liab-coated solid vuam hlau rau qhov tsis muaj vuam hlau. Weld hlau cheeb tsam muaj zoo tshaj plaws hluavtaws thev naus laus zis thaum sib tsoo vuam flux siv. Nrog rau kev xa tawm ntau dua, kev ua haujlwm siab thiab kev siv zog tsawg ntawm kev ua haujlwm, thiab lwm yam.

DAIM NTAWV THOV
Cov vuam vuam siv yog siv rau vuam tseem ceeb cov txheej txheem ntawm cov pa roj carbon uas tsis tshua muaj hlau thiab cov hlau tsis tshua muaj hlau. Xws li lub rhaub dej, lub nkoj siab los ntawm cov tshuaj ua haujlwm thiab chaw nres tsheb fais fab nuclear, txuas hniav thiab nkoj, thiab lwm yam.

Qhov ntau thiab tsawg ntawm cov hlau: Txoj kab uas hla Φ （mm） 2.0、2.5、3.2、4.0、5.0

Cov yam ntxwv ntawm cov tshuab uas muaj hlau txuas: Tshaj nrog GB / T14957-94
