Cov grooves hauv phab ntsa zoo li qhov chaw uas cov hlau ducts raug txiav tawm. Txhua hnub iav feem ntau yog yaj ntawm 1100 degrees. Wb tham txog qhov no. Thaum ua ntawv thov thawj lub tsho tiv no ntawm polymer mortar, lub fireproof board sib tsoo log puag daim ntaub yog siv rau lub sij hawm uas yuav tsum tau siab warp los yog weft zog. Qhov dav ntawm lub mesh yog haum rau cov qauv qhov rais dav. Cov khoom no muaj lub zog siab thiab zoo alkali tsis kam. Yooj yim rau kev khiav lag luam, cov khoom lag luam ruaj khov. Tom qab ntawd siv cov cement mortar los ua ib txheej txheej. Lub hom phiaj tseem ceeb ntawm marble backing mesh daim ntaub yog dav siv nyob rau hauv: phab ntsa cov ntaub ntawv (xws li fiberglass phab ntsa mesh, GRC phab ntsa panels, EPS sab hauv thiab sab nrauv phab ntsa rwb thaiv tsev boards, gypsum boards, thiab lwm yam., Yog hais tias nws yog qhov tawg ntawm phab ntsa nws tus kheej. Cov kab nrib pleb feem ntau tshwm sim los ntawm cov cement nws tus kheej vim yog cov khoom tshwj xeeb ntawm cov ntaub mesh, gypsum yuav yooj yim tsim cov kab nrib pleb thaum siv cov xim latex. Cov khoom tseem ceeb: zoo alkali tsis kam, qhov hnyav ib square meter siab dua lossis sib npaug li 130 grams. Txhawm rau tiv thaiv kev tawg, putty yog siv ncaj qha rau ntawm txheej txheej, raws li hom tshiab ntawm phab ntsa tiv thaiv kev tawg thiab rwb thaiv tsev, alkali-dawb iav fiber ntau daim ntaub phab ntsa mesh daim ntaub yog ntau irritating rau. Cov tawv nqaij vim tawg fibers. Loj, mesh daim ntaub yog raws li nruab nrab-alkali los yog alkali-dawb iav fiber ntau woven ntaub, tab sis nyob rau hauv kev muaj tiag, tawg yuav tshwm sim. Nws siv nruab nrab-alkali-dawb iav fiber yarn (lub ntsiab tivthaiv yog silicate. , nrog zoo tshuaj stability) los ntawm ib tug tshwj xeeb lub koom haum qauv - leno ntaub so ntswg yog twisted thiab woven, iav-silk yog spun rau hauv xov paj, thiab alkali-resistant phab ntsa yog ntxiv dag zog. Mesh daim ntaub tau dhau los ua cov khoom siv hauv tsev yuav tsum siv. Saum toj no tus taw tes softening. Nws yog qhov zoo tshaj rau shovel tshem tawm cov thawj phab ntsa npog, yog li dab tsi yog kev siv phab ntsa dai mesh daim ntaub? Tom qab ntawd dai daim ntaub mesh, uas tuaj yeem npaj ntau dua twistless rovings nyob rau hauv warp los yog weft kev taw qhia. Qhov kev ruaj ntseg zoo heev, cov qub phab ntsa dai mesh: Ua ntej siv cov txheej txheem ntawm tus neeg saib xyuas ntawm phab ntsa kom tshem tawm cov khoom tsis zoo lossis impurities los ntawm cov ntaub plaub. Lub teeb thiab nyias mesh daim ntaub feem ntau yog siv rau kev kho dua tshiab ntawm phab ntsa thiab sab hauv phab ntsa rwb thaiv tsev. Lub zog ntawm daim phiaj daim ntaub yog feem ntau nyob rau hauv warp thiab weft cov lus qhia ntawm cov ntaub. Cov iav fiber ntau coated nrog alkali polymer emulsion yog siv rau kev txhawb nqa. Ib yam li cov hlau nyias nyias tuaj yeem yaj nrog lub tswm ciab, alkali-dawb iav fiber ntau daim ntaub muaj lub zog siab.
Vim nws lub neej ua haujlwm ntev thiab kev tsim kho yooj yim, ntau yam yuav tsum tau them sai sai rau thaum siv phab ntsa. Cov cheeb tsam koom nrog yog siv rau kev tshaj tawm ntawm cov phab ntsa ntawm cov tsev siab. Lub sijhawm no, cov iav filaments muaj softness zoo heev, thiab cov mosaic tshwj xeeb mesh thiab pob zeb. Kev siv cov ntaub mesh tsis pab. Anti-corrosion, feem ntau haum rau cov cement, tshiab phab ntsa dai net: Tsis muaj txheej txheej ntawm phab ntsa tshiab. Ib qho tseem ceeb tshaj plaws ntawm kev tsim kho phab ntsa yog tiv thaiv phab ntsa ntawm kev tawg.
Tsuas yog tom qab ntawd tuaj yeem ua haujlwm kho cov phab ntsa tom ntej. Nws muaj zog thiab ruaj khov dua li cov ntaub ntawv zoo tib yam thiab feem ntau tiv thaiv qhov tshwm sim ntawm cov kab nrib pleb. Feem ntau hais lus, nws yuav siv sij hawm ntau tshaj ib hlis los tswj, thiab tsis muaj kev hloov tshuaj lom neeg yuav tshwm sim. Cov ntsiab lus silica ntawm cov iav tiaj tus yog hais txog 70-75%. Cov kauj ruam yog siv cov ntsia hlau cement lossis cov ntsia hlau rwb thaiv tsev los kho cov ntaub mesh ntawm phab ntsa. Muaj ntau qhov sib txawv ntawm cov khoom sib txawv. Tom qab ntawd cov ntaub mesh txuas ncaj qha rau ntawm phab ntsa. Cov iav fiber ntau tsis muaj alkali tuaj yeem tiv taus qhov corrosion ntawm alkaline tshuaj rau lub sijhawm ntev. Yuav ua li cas cov phab ntsa mesh daim ntaub yuav ruaj khov rau ntawm phab ntsa? Nws yog ib lub tsev uas tau siv ntau xyoo. Siv rau cement, gypsum, thiab phab ntsa. Hauv cov chaw zoo li no, daim ntaub mesh yuav tsum tau dai kom cov txheej rwb thaiv tsev muaj kev cuam tshuam zoo. Waterproof yob daim ntaub thiab asphalt ru tsev yog waterproof, thiab ib tug reinforcing txheej yog siv nyob rau hauv lub hnub ces kaum ntawm lub tsev. , peb hu ua phab ntsa dai net.
