Sio2 hydrophobic yog dab tsi?

Silica los ntawm silane treatmen lossis silica los ntawm kev kho mob saum npoo. Dawb amorphous hmoov zoo. Nws yog hydrophobic. Soluble hauv caustic potash (sodium). Tsis txhob yaj hauv dej thiab kua qaub. Cov-mob toxic. Tsis qab. Tsis-corrosive. Tsis muaj hlawv, tsis muaj oxidation. Kev kub siab tsis ua kom lwj. Cov sodium ions raug tshem tawm los ntawm ion pauv los ntawm daim iav dej, thiab hydrochloric acid ntxiv rau kom nqa cov kua qaub ua kom rov muaj zog, thiab cov kuab tshuaj dimethyldichlorosilane monomer ntxiv rau kev kho hydrophobic, thiab cov kuab tshuaj yog tshem tawm thiab qhuav. Feem ntau siv los ua cov roj hmab silicone reinforcing tus neeg sawv cev, cov cav ntim roj hmab, thiab cov thickener rau txheej thiab inks.
