Khoom Description

Nws yog ib qho byproduct ntawm smelting ntawm silicon thiab feem ntau yog siv los ua ib qho ntxiv hauv pob zeb los txhim kho nws lub zog thiab kav ntev. Silica Fume lub thermal rwb thaiv tsev zoo heev ua rau nws tsim nyog rau cov ntawv thov kub, nrog rau cov khoom siv hluav taws xob, cov khoom siv hauv tsev, thiab lwm yam khoom siv kub. Nws qhov me me me me thiab thaj chaw siab siab muab cov thermal rwb thaiv tsev zoo, nrog rau cov khoom zoo refractory uas tuaj yeem tiv taus qhov kub thiab txias. Tsis tas li ntawd, Silica Fume yog hluav taws-resistant, tsis-combustible, thiab non-toxic, ua rau nws muaj kev nyab xeeb thiab nrov xaiv rau ntau yam kev lag luam daim ntaub ntawv.
