1.Xaiv cov khoom siv kom tsim nyog
Hauv cov viscosities sib txawv thiab cov tshuab, nws yog qhov tsim nyog los xaiv cov khoom siv kom tsim nyog. Hauv cov tshuab txiav nrog qis viscosity, high- ceev tuab dispersers tuaj yeem xaiv rau qhov kev faib tawm ntawm fumed silica.
Hauv Silicone roj hmab muaj siab viscosity, nws yog qhov tsim nyog los xaiv cov kneaders lossis qhib cov mills, thiab lwm yam rau cov hmoov sib xws. Hauv cov hmoov hmoov, nws yog ib qho tsim nyog los xaiv cov kev tshem tawm xws li peb - ceev dispersion lossis sib tsoo dispersion. Tsis tas li ntawd, cov yam ntxwv ntawm cov khoom siv kuj yuav tsum tau txiav txim siab, rau cov khoom siv kom sov, rau cov khoom siv hluav taws xob, thiab lwm yam ua tau raws li cov haujlwm txawv teb chaws.
2.Xaiv ib txheej txheem rho tawm tsim nyog
Txawv sib txawv ua ke, sijhawm sijhawm dispersion, thiab cov nyiaj ntawm dispersed cov ntaub ntawv tag nrho muaj qhov cuam tshuam tseem ceeb ntawm cov hmoov dispersion. Nws tsis yog qhov teeb meem uas lub sijhawm ntev lossis ntau dua qhov kev siv, ntau dua rau nws ua kom tawg. Ntawm no, peb yuav tsum tau coj mus rau hauv tus account lub zog txuag thiab seb puas muaj qhov teeb meem dhau - dismersion. Tshaj -}}- agglomeration lossis cov qauv kev puas tsuaj, ua rau fumed silica tsis tau ua tau zoo. Yog li ntawd, xaiv ib txheej txheem txheej txheem txheej tsim nyog yog qhov tseem ceeb tshaj plaws.
3.Xaiv cov kev zam tsim nyog
Cov AIDS DIST tau ua rau txo qis npoo ntawm fumed silica thiab cov kev sib cav sib ceg, yog li ua tiav lub hom phiaj ntawm kev txo cov viscosity. Lub caij no, tus neeg sawv cev dispersting yuav ua ib txheej hluav taws xob ob npaug rau saum npoo ntawm fumed silica hais. Qhov no ob txheej hluav taws xob yuav tsim electrostatic repulsion, ua rau nws nyuaj rau cov hais kom aggregate thiab yog li tswj hwm lub xeev dispersed. Cov kev xaiv ntawm cov khoom sib ntxiv uas tsim nyog yog qhov tseem ceeb tshaj plaws hauv kev dispersion thiab yog ze rau nws cov kev tso cai.
