1. Muaj nuj nqi thiab tus qauv
Fiberglass mesh daim ntaub yog cov khoom siv ntxiv rau cov thermal rwb thaiv tsev ntawm phab ntsa sab nraud. Nws lub luag haujlwm tseem ceeb yog: txhawm rau txhim kho cov neeg kho tshuab lub zog ntawm cov txheej txheej saum npoo av, xyuas kom muaj kev sib txuas ntawm qhov tsis kam ntawm cov txheej txheem, disperse lub shrinkage siab thiab thermal rwb thaiv tsev kev ntxhov siab ntawm txheej txheej, zam kev nyuaj siab concentration, thiab tiv thaiv nto tawg los ntawm kev hloov. nyob rau hauv qhov kub thiab av noo nyob rau hauv cov xwm thiab tej yam kev puas tsuaj. Yog li ntawd, alkali-resistant iav fiber mesh plays ib qho tseem ceeb luag hauj lwm thiab lub luag hauj lwm nyob rau hauv lub sab nraud thermal rwb thaiv tsev system, yog li kev xaiv ntawm ib tug zoo iav fiber mesh kuj yog ib qho tseem ceeb ib feem ntawm kev ua kom cov kev zoo ntawm lub sab nraud thermal rwb thaiv tsev system.
Tam sim no lub teb chaws tus txheej txheem rau kev rwb thaiv tsev sab nrauv phab ntsa (JG149-2003): lub alkali-resistant tensile tawg lub zog ntawm iav fiber mesh nyob rau hauv warp thiab weft cov lus qhia yuav tsum tsis txhob tsawg tshaj li 750N / 50mm, thiab tuav tus nqi ntawm alkali -resistant tensile tawg lub zog yuav tsum tsis pub tsawg tshaj li 50 feem pua, ib square meter Rice nyhav Ntau tshaj los yog sib npaug zos rau 130 grams. JG158-2004 iav fiber ntau mesh warp thiab weft alkali-resistant tensile breaking zog yuav tsum tsis txhob tsawg tshaj li 1250N / 50 hli, alkali-resistant tensile breaking zog tuav tus nqi yuav tsum tsis txhob tsawg tshaj li 90 feem pua, thiab qhov hnyav ib square meter yuav tsum ntau tshaj los yog sib npaug rau 160 grams.
Tam sim no, cov ntaub mesh siv nyob rau hauv cov kab hluav taws xob sab nraud hauv kuv lub teb chaws kev lag luam hnyav txog 130 grams ib square meter, thiab nws lub zog feem ntau yog tsawg. Nws lub zog tawg ib txwm yog 1000N / 5cm, lossis qis dua. Vim li no: cov kev taw qhia ntawm daim phiaj daim phiaj rau sab nrauv phab ntsa rwb thaiv tsev qhov project yuav tsum tau standardization, thiab qhov tsim nyog tau txais kev pom zoo ntawm muas alkali-resistant iav fiber mesh daim ntaub yuav tsum tau ua ua ntej siv. Nyob rau hauv kev tswj kev tawg ntawm sab nrauv phab ntsa rwb thaiv tsev, tsis tsuas yog cov rwb thaiv tsev cov ntaub ntawv yuav tsum muaj ib tug tej yam tensile lub zog thiab qhov kawg tensile lub zog, tab sis kuj lub anti-crack tiv thaiv txheej cov ntaub ntawv yuav tsum muaj txaus tensile zog. Vim li no, thaum xaiv alkali-resistant fiberglass mesh, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau seb lub zog tensile ntawm alkali-resistant fiberglass mesh nws tus kheej ua tau raws li tus qauv.
2. Kev siv alkali-resistant iav fiber mesh daim ntaub compounded nyob rau hauv plastering mortar
Ntawm ib sab, nws tuaj yeem ua kom muaj zog tensile ntawm cov txheej tiv thaiv zoo. Ntawm qhov tod tes, vim tias nws tuaj yeem cuam tshuam qhov kev ntxhov siab zoo, nws tuaj yeem cuam tshuam cov kab nrib pleb uas yuav raug tsim los rau hauv ntau cov kab nrib pleb me me, yog li tsim nws cov kab nrib pleb. Cov khoom siv txheej txheej thiab txheej txheej yog qhov tseem ceeb rau alkali tsis kam ntawm iav fiber ntau, thiab iav fiber ntau muaj qhov tseem ceeb rau kev ua haujlwm ntev alkali.
Thaum siv cov iav fiber ntau mesh:
Qhov dav sib tshooj ntawm cov ntaub ntawv alkali-resistant mesh tsis tsawg dua 50 hli, thiab cov ntaub alkali-resistant mesh ntawm cov ces kaum sab hauv yuav tsum tau sib tshooj nrog stubble, thiab qhov dav yog ntau dua los yog sib npaug li 50 hli, thiab cov ces kaum sab nrauv yog ntau dua. tshaj los yog sib npaug li 200mm. Thaum lub sij hawm tsim kho, daim phiaj alkali-resistant daim phiaj yuav tsum tau pw tiaj tus, tsis muaj wrinkles, thiab lub mortar yuav tsum tag nrho.
3. Yuav ua li cas txheeb xyuas cov teeb meem zoo ntawm alkali-resistant iav fiber mesh
① Cov ntaub iav fiber ntau Nws cov iav fiber ntau yog ua los ntawm cov iav khib nyiab xws li lub raj mis npias. Cov txheej txheem ntau lawm yog av nplaum crucible kos duab, uas yog cov txheej txheem ntau lawm txwv tsis pub los ntawm lub xeev, thiab cov txheej txheej saum npoo tsis yog alkali-resistant emulsion. Los ntawm qhov kev xav ntawm kev xav: kev ua haujlwm yog qhov ntxhib, feem ntau muag ntau hauv kev ua lag luam, feem ntau tshwm sim ntev tsis txaus, qhov hnyav tsis txaus, tawg tom qab ob lub folds, cov pob qij txha xoob yog yooj yim hloov, thiab yooj yim rau puncture ntawm daim tawv nqaij. Hom ntaub mesh no feem ntau poob nws lub zog tom qab ob lub hlis thaum siv hauv txheej rwb thaiv tsev. Yog hais tias lub mortar tau khob tawm thiab cov ntaub mesh raug tshem tawm, cov iav fiber ntau yuav ua hmoov nrog lub teeb sib tsoo.
② Muaj lwm hom imitation platinum fiberglass mesh daim ntaub, kuj hu ua cov xov paj sib xyaw. Qhov no yog ib qho zoo imitation iav fiber ntau, tab sis feem ntau nws yog ib co ca iav cullet nrog zoo pob tshab nyob rau hauv kev xaiv ntawm pov tseg iav, thiab lub fiber txoj kab uas hla yog me me. Qee lub sij hawm nws nyuaj rau txiav txim siab nws qhov tseeb ntawm qhov chaw, tab sis nws qhov zoo tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm alkali-resistant mesh daim ntaub nyob rau sab nrauv phab ntsa rwb thaiv tsev.
③ Cov txheej txheem mesh nrog cov khoom zoo siv platinum iav fiber ntau ua cov khoom siv hauv paus, thiab ob qho tib si xaiv cov khoom siv thiab cov txheej txheem weaving yog qhov tshwj xeeb. Txhua txheej emulsions siv tau zoo alkali tsis kam. Zoo alkali tsis kam thiab siab warp thiab weft tensile lub zog ua rau cov khoom muaj tes zoo thiab kev tsim kho zoo, uas tuaj yeem txo cov nqi ntawm plastering mortar.
④ Cov kev siv ntawm alkali-resistant iav fiber mesh daim ntaub nyob rau hauv sab nraud thermal rwb thaiv tsev systems:
Sab nrauv phab ntsa rwb thaiv tsev feem ntau yog siv: 3 × 3 × 45 grams, 5 × 5 × 80 grams;
Lub thermal rwb thaiv tsev ntawm cov phab ntsa sab nrauv txais yuav: 5 × 5 × 130 grams, 5 × 5 × 145 grams;
Sab nrauv phab ntsa roj hmab hmoov particle system txais: 5 × 5 × 160 grams;
Sab nrauv phab ntsa pobzeb los yog rwb thaiv tsev txheej txog li ob meters: 3 × 7 × 10 × 300 grams.
