Yuav ua li cas silica ua haujlwm hauv matting tus neeg sawv cev?

Mechanism ntawm Matting

Raws li cov xim zaj duab xis dries, tusyees dispersed silica matting tus neeg sawv cev hais hauv zaj duab xis thov tsim micro-roughening ntawm saum npoo.

Qhov teeb meem tsis sib xws yog nthuav dav los ntawm qhov micro-ntxhib saum npoo kev cuam tshuam qhov pom ntawm lub ntsej muag lossis lub ntsej muag txaj (Daim Duab 2).

Yam Cuam Tshuam Lub Matting Zoo

Peb qho tseem ceeb ntawm silica nta txiav txim siab qhov ua kom zoo ntawm ntau yam khoom siv silica :

.cov ntim (porosity)

.particle loj

.surface kev kho mob

Pore Volume

Peb cov silica hais tuaj yeem pom tau zoo li daim txhuam cev me me.Qhov porosity ntawm no cov khoom ntxeem tau zoo heev yog qhia los ntawm cov pore ntim, uas qhia qhov nyiaj ntawm sab hauv voids hauv silica particle.Qhov ntau dua qhov pore ntim ntawm silica, ntau qhov kev ua tau zoo yog peb silica qib (saib Daim duab 5) .Qhov no yog vim muaj qhov loj ntawm cov porosity siab dua ntais, yog li muab ntau dua ntawm cov nplais nyhav rau ib qhov hnyav.

Ntawv Particle

Cov neeg ua hauj lwm matting muaj nyob rau hauv ntau qhov ntawm qhov tseeb txhais qhov nruab nrab cov khoom nruab nrab, nrog cov khoom siv tau tswj tau zoo tshaj plaws.Qhov loj dua qhov nruab nrab qhov loj me, qhov ntau dua qhov zoo ntawm cov matting (saib Daim Duab 6). Qhov no yog vim muaj qhov loj dua qhov tsim kom muaj qib siab tshaj plaws ntawm qhov chaw micro-roughening.Tiam sis, qee qhov me me tuaj yeem ua rau tsis tsim nyog nto

tsos lossis xav tias, yog hais tias nws yog ib yam nkaus thiab ntxhib.Optimum matting efficiency nrog siv xim zaj duab xis

cov khoom tsuas yog ua tiav los ntawm kev xaiv SYLOID ®matting tus neeg sawv cev nrog tus me me qhov tsim nyog nyob rau hauv kev sib raug zoo nrog cov khoom tuab ntawm cov xim txheej zaj duab xis.

Nto Kho (Daim Duab 7)

Qee tus ntawm peb cov khoom ua kua silica yog kho kom zoo nrog ua tib zoo xaiv cov organic sib tov (piv txwv li waxes). Kev kho cov ciab tiv thaiv kev ua kom haum, tshwj xeeb hauv kev tsim cov kev sib zog, tshwj xeeb tshaj yog nyob rau cov uas tsis tshua muaj khov, ntshiab lacquers.Wax kho cov khoom tseem tuaj yeem ua rau muaj txiaj ntsig zoo rau

txhim kho lwm yam khoom nto, xws li mar thiab khawb kuj. Cov khoom siv kho mob khoom siv roj tau tuaj yeem ua rau pom kev qis tshaj qhov ua tau zoo dua li cov khoom tsis muaj qhov sib thooj nrog cov khoom siv zoo ib yam.Puas cov silica matting tus neeg sawv cev, lwm cov qauv thiab daim ntawv thov cov khoom muaj feem cuam tshuam rau qhov kawg.

Qhuav Zaj Duab Xis Thickness (Daim Duab 8)

Tshaj qhov siab zaj duab xis qhov hnyav ntawm theem sib ntxiv ntawm ib qho kev xaiv tus neeg saib xyuas cov khoom lag luam, qhov qis dua ntawm cov txiaj ntsig matting. Txhawm rau cov tuab tuab cov duab xis zoo, kev xaiv ntawm qhov loj tshaj plaws tuaj yeem pom zoo cov khoom lag luam tau pom zoo.

Lwm Yam (Daim duab 9)

Raws li qhov yuav tsum tau ntxiv theem ntawm matting cov neeg sawv cev los ua kom tiav qhov teeb meem sib txawv nyob ntawm tus nqi thiab qhov ua haujlwm ntawm cov yeeb yaj kiab shrinkage uas tshwm sim thaum lub sij hawm ziab, qhov ua kom zoo ntawm cov neeg ua hauj lwm matting kuj tseem tuaj yeem los ntawm:

.cov ntaub tshuab (txawv cov khoom siv kho)

Cov. cov khib nyiab cov ntsiab lus (lossis tus nqi ntawm cov nrov tsis haum xws li cov kuab tshuaj)

. hom kev hnyav (txawv vapor siab)

.qhov hom kev ziab (nrawm lossis qeeb kom qhuav)
