Hydrophobic silica (Precipitated Silica)

Hydrophobic silica (Precipitated Silica)

Hydrophobic dawb cov pa roj carbon dub yog ib qho ntxim nyiam amorphous silica nrog cov hmoov av dawb. Nws lub ntsiab me me yog qhov nano khoom. Cov khoom zoo tshaj plaws, xws li qhov kawg qhov me me yog 5 ~ 6um. Tom qab sib tov nrog roj hmab, yas thiab xim, nws tuaj yeem ua rau cov khoom muaj txhua yam zoo ntawm lub cev. Nws yog siv los ua lub teeb xim ntawm roj hmab thiab khoom siv roj hmab. Tus neeg ua haujlwm zoo, ua rau kev txo tus nqi ntawm cov roj hmab, txo nqi, ntawm kev siv roj hmab, hnav cov tshuaj, ua kom tsis txhob deformation, nce cov roj ua haujlwm; siv lo yas yas tawv, cov khoom siv lub teeb, yooj yim tshem film thiab molding, txo qhov hnyav ntawm cov khoom; siv nyob rau hauv hlau thiab cable, yuav ua kom nws qhov kev ua haujlwm hauv tsev; siv nyob rau hauv cov xim muaj hlau, nws yog ib tug zoo thickener; cov xim muaj kub zoo heev, ua li no cov khoom siv dav siv hauv roj hmab, yas, tawv, xim, kev ua si kev cai khoom thiab lwm yam lag luam.

Cov chaw kawm:

Hydrophobic silica muaj kev ua dej kub siab heev thiab muaj cov pob tshab thiab cov ntsiab lus nyob hauv cov khoom siv roj hmab. Nws yog tshwj xeeb tshaj yog tsim rau lub teeb, ci, pob tshab thiab translucent roj hmab cov khoom. Tsis tas li ntawd xwb, nws yuav siv los ua ib qho kev sib txuas lus rau cov tshuaj latex, kev tiv thaiv los ntawm cov xim tha xim, cov tshuaj nplaum, thixotropic tus neeg sawv cev, txhua yam yas yeeb yam qhib kab , tshuaj tua kab, tshuaj, cov khoom nplaum thiab cov khoom siv thiab tshuaj txhuam hniav , yuav siv tau hauv nruab nrab thiab qib siab atomic ash series khoom.
