4. Txhim kho cov dej kub siab kuj
Silica Fume tuaj yeem muab kev tiv thaiv ntxiv rau hauv qhov chaw kub kub, yog li nws daim ntawv thov nyob rau hauv qhov chaw kub kub heev. Qhov sib ntxiv ntawm Silica Fume tuaj yeem txhim kho lub thermal stability ntawm pob zeb ua, txo qhov hloov ntawm qhov kub, thiab txhim kho lub thermal tiv thaiv ntawm pob zeb ua. Qhov no yog tshwj xeeb yog ib qho tseem ceeb rau cov pob zeb ua hauv hluav taws lossis cov dej kub ua haujlwm. Los ntawm kev txhim kho qhov kub siab kuj ntawm cov pob zeb ua kom muaj cov pob zeb ua si, Silica Fume tuaj yeem zam lub zog ploj thiab qhov chaw tawg tshwm sim los ntawm qhov kub thiab txias.
