PPT Silica rau Cov Tshuaj Txhuam Hniav li Thickening
Thickener yog qhov tseem ceeb raw khoom los ua tus tswj cov tshuaj txhuam hniav. Nws lub luag haujlwm tseem ceeb yog raws li nram no: (1) Ua kom cov tshuaj txhuam hniav muaj qhov sib zog thiab tsis sib xws, tsis muaj kev xav, thiab muaj lub cev zoo.
(2) Cov tshuaj txhuam hniav muaj lub cev pob txha, thiab cov tshuaj txhuam hniav uas muaj cov tshuaj tsis tuaj yeem nyob twj ywm hauv tus txhuam hniav thiab tsis muaj dej khov, yog li nws muaj kev ua kom zoo zoo.
(3) Thaum txhuam hniav, cov tshuaj txhuam hniav yoojyim yooj yim los faib thiab muaj kev sib tw zoo.
(4) Nws muaj kev ruaj ntseg zoo thiab tsis yooj yim rau biodegrade. Thaum lub sij hawm cia, qhov muab tshuaj txhuam yog ruaj khov thiab tsis stratified. Nws tsis cais dej los ntawm muab tshuaj txhuam thiab tsis cuam tshuam rau qhov tsw qab thiab xim ntawm cov tshuaj txhuam hniav. Nws muaj kev ruaj ntseg zoo.
(5) Ua kom zoo nkauj thiab glossy paste, tus txheeb ze yog sib npaug, thiab qhov muab tshuaj txhuam tsis tau rov qab los ua kom sib npaug.
(6) Nws muaj kev sib raug zoo nrog lwm yam khoom ntawm cov tshuaj txhuam hniav, tshwj xeeb tshaj yog cov tshuaj nquag, thiab kev sib haum xeeb zoo.
Cov khoom ntawm cov nplaum thiab nws cov luag hauj lwm hauv cov tshuaj txhuam hniav yog qhov tseem ceeb los kawm txog kev ruaj ntseg ntawm cov tshuaj txhuam hniav. Cov tshuaj txhuam hniav yog sib tov ntawm cov theem ua kua thiab kua theem. Nws theem theem yog abrasive hmoov. Nws qhov loj me me yog nruab nrab ntawm 5 thiab 40 microns. Cov hmoov thiab kua yog homogeneously emulsified los ntawm surfactant (foaming agent) los tsim kom muaj kev ruaj ntseg ncua. Tus tshaj tawm ntawm nag lossis daus thiab sib cais ntawm cov khoom ua kua hauv cov dej yog inversely proportional rau cov viscosity ntawm cov kua, thiab kuj muaj feem xyuam rau cov rheology ntawm kua. Txhawm rau ua kom cov hmoov sib xyaw hauv cov dej ua kua, nws tsim nyog los txhim kho cov rheology ntawm cov kua los ntawm txoj hnyav quav, kom cov tshuaj txhuam hniav muaj peev xwm ruaj khov.
Precipitated silica yog ib qho kev xaiv zoo rau cov tshuaj txhuam hniav kom tuab. Peb cov khoom JS-185C3 yog tsim rau cov tshuaj txhuam hniav. Specification yog li hauv qab no:

Qhov zoo ntawm JK SILICA li Thickening Agent:
(1) Zoo viscosity thiab thixotropy.
(2) Nws yog ib qho yooj yim mus disperse thiab swell nyob rau hauv qhuav ntawm gypsum tsis muaj agglomeration.
(3) Nws muaj dej txaus txhuam thiab nws yooj yim los ua ke lwm cov ntaub ntawv hauv cov tshuaj txhuam hniav.
(4) Nws tsis ua hauj lwm zoo rau cov kua roj carbon monoxide thiab ntsev, thiab yuav tsis tsim kev degradation uas cuam tshuam cov tshuaj txhuam hniav thaum lub sij hawm nws txee lub neej.
(5) nws tuaj yeem nqa tau zoo rau qhov essence. Cov tshuaj txhuam hniav yuav tsum tsis txhob muab ib qho tsw ntxhiab tsw los yog saj.
(6) Tsis tuaj yeem cuam tshuam txog cov xim ntawm cov tshuaj txhuam hniav
