Nrog rau kev txhawb nqa kev tsim lub zog-txuag txoj cai, lub zog-txuag tshuab ntawm sab nrauv phab ntsa rwb thaiv tsev yog tsim nyob rau hauv tag nrho viav vias. Cov ntaub mesh woven los ntawm iav fiber ntau yog siv los ua cov ntaub hauv paus, thiab alkali-resistant iav fiber mesh daim ntaub ua los ntawm polymer alkali-resistant txheej rau saum npoo yog siv dav. Nws yog faus rau hauv txheej plaster los txhim kho cov txheej txheem tiv thaiv. mechanical zog thiab tawg kuj. Hauv kev sim cov khoom siv hluav taws xob sab nrauv phab ntsa, muaj 6 cov qauv uas muaj fiberglass mesh daim ntaub, thiab lawv txoj kev sim sib txawv. Cov ntsiab lus yog raws li nram no.

(2) Raws li cov qauv ntawm JG149-2003 "Expanded Polystyrene Board Thin Plastering Sab nrauv phab ntsa rwb thaiv tsev".
① Chav tsev loj dua lossis sib npaug li 130g / m2, kuaj raws li cov cai ntawm GB / T9914.3-2001;
② Alkali-resistant breaking zog (warp thiab weft) Ntau dua los yog sib npaug ntawm 750N / 50mm, npaj raws li cov kev cai ntawm Hom I hauv Table 1 ntawm GB / T7689.2-2001, thiab cov tshuaj alkali yog 5% NaOH aqueous tov ntawm (23 ± 2) degree. Yog xav paub meej txog cov txheej txheem xeem, thov mus saib Tshooj 6.6.2.2 ntawm JG149-2003. Soak rau 28 hnub, tshem tawm thiab tsau rau hauv kais dej rau 5 feeb, ces yaug nrog dej ntws rau 5 feeb, ces qhuav nyob rau hauv qhov cub ntawm (60 ± 5) degree rau 1 teev, cia rau 24 teev ua ntej siv;
③ Alkali tiv thaiv lub zog tuav tus nqi (warp thiab weft) Ntau dua lossis sib npaug li 50%, npaj raws li qhov yuav tsum tau muaj ntawm Hom I hauv Table 1 ntawm GB / T7689.2-2001, cov tshuaj alkali yog 5% NaOH aqueous tov ntawm (23 ± 2) degree. Yog xav paub meej txog cov txheej txheem xeem, thov mus saib Tshooj 6.6.2.2 ntawm JG149-2003. Soak rau 28 hnub, tshem tawm thiab tsau rau hauv kais dej rau 5 feeb, ces yaug nrog dej ntws rau 5 feeb, ces qhuav nyob rau hauv qhov cub ntawm (60 ± 5) degree rau 1 teev, cia rau 24 teev ua ntej siv;
④ Fracture strain (warp thiab weft) Tsawg dua lossis sib npaug li 5.0%, ntsuas raws li GB/T7689.5-2001;
(3) Raws li cov qauv ntawm JGJ144-2004 "Technical Regulations for Exterior Wall Insulation Engineering".
① Alkali-resistant tensile breaking lub zog (warp thiab weft) Ntau dua los yog sib npaug rau 750N / 50mm, kuaj raws li Daim Ntawv Ntxiv A.12 hauv JGJ144-2004, 20 daim txhua hauv cov lus qhia warp thiab weft. Qauv loj: 300mm × 50mm, tsau rau hauv (23 ± 2) degree, 5% NaOH aqueous tov rau 28d, tshem tawm thiab tsau rau hauv kais dej rau 5min, ces yaug nrog dej ntws rau 5min, ces qhuav nyob rau hauv (60 ± 5) degree qhov cub rau 1h, khaws cia tom qab 24 teev;
② Alkali-resistant tensile fracture zog tuav tus nqi (warp thiab weft kev taw qhia) Ntau tshaj los yog sib npaug rau 50%, ceev txoj kev, siv NaOH, KOH, thiab Ca(OH) 2 tov alkali tov thiab tsau ntawm 80 degree rau 6 teev;
(4) Raws li cov qauv ntawm JC/T841-2007 "Alkali-resistant iav fiber mesh".
① Qhov zoo ntawm ib cheeb tsam yuav tsum tau pom zoo los ntawm ob tog ntawm kev muab khoom thiab kev thov. Tus nqi ntsuas qhov tseeb yuav tsum tsis pub tshaj ± 8% ntawm tus nqi nominal thiab yuav tsum tau sim ua raws li cov kev cai ntawm GB / T9914.3;
② Lub tensile tawg lub zog yuav tsum tau sib txawv raws li qhov nominal pawg ib cheeb tsam. Piv txwv li: yog tias qhov loj ntawm ib chav tsev nyob hauv 161 ~ 170g / m2, nws lub zog tensile tawg yog ntau dua lossis sib npaug rau 1300N / 50mm.
