Sab nraud phab ntsa rwb thaiv tsev sab nraud muaj ntau hom ntaub ntawv, suav nrog cov ntaub qhwv ntsej muag, cov ntaub pua av, ceramic pobzeb), thiab lwm yam khoom siv yuav tsum tau siv raws li qhov yuav tsum tau ua. Piv txwv li, rwb thaiv tsev board yog feem ntau cov khoom siv nyob rau hauv qhov qhib cua ntawm ntau cov chaw tsim khoom. Lub rooj sib tham rwb thaiv tsev yog nthuav tawm hnub ci thiab nag, uas tuaj yeem yooj yim ua rau muaj kev deformation thiab shrinkage ntawm nws cov qauv. Ib qho ntxiv, yog tias lub rwb thaiv tsev board ua qias zus, nws tuaj yeem cuam tshuam tsis zoo rau kev sib raug zoo lub zog.
Tshwj xeeb, muaj qhov khoob ntawm cov laug cam rwb thaiv tsev, thiab sau cov khoob ntawm txoj kev txhaj tshuaj ntsiav yog qhov ua rau cov kab sib tov tsis tu ncua rau saum npoo ntawm lub plastering collab; Txoj kev sib raug zoo ntawm lub rwb thaiv tsev board yog qhov tsawg heev, thiab khoob ntawm cov txheej txheem pasting tseem yuav cuam tshuam rau lub zog bonding. Yog hais tias lub hollowing yog pom tseeb, cov kab nrib pleb yuav tshwm sim saum npoo. Lub plastering cug txheej yog ib yam dhau los npog cov rwb thaiv tsev pawg thawj coj. Tom qab cov xim pleev xim, pom tseeb ntawm alkali-resistant iav fiber ntau ntaub thiab thauj tog rau nkoj bolts yuav tshwm sim. Yog tias lub plastering cug txheej yog cov tuab heev lossis yog tias txheej thib ob tau thov ua ntej txheej txheej txheej tau qhuav, shrinkage tawg yog yuav tshwm sim.
Nyob rau hauv sab nraud phab ntsa rwb thaiv tsev kev ua haujlwm, yintong yt inorganic hospion system yog ib hom mesh dawb-dawb tsis xav tau daim ntaub mesh lossis rivets. Ntxiv nrog rau yintong yt system, lwm lub phab ntsa sab nraud phab ntsa yuav tsum tau siv cov ntaub pua fiber ntau nrog cov alkali tsis kam. Yog tias lub xov tooj iav fiber ntau muaj qee qhov zirconium yog siv, cov alkali tsis kam ntawm lub mesh thiab lub sijhawm ntev ruaj khov ntawm cov phab ntsa phab ntsa sab nraud tuaj yeem txhim kho. Hom khoom no ua lub luag haujlwm zoo hauv kev txhim kho lub zog ntawm tag nrho cov kab ke. Lwm qhov teeb meem tsim nyog ntawm kev saib xyuas yog lub neej ntawm cov dej khov. Qhov tsim ntawm cov dej khov yog feem ntau yog vim txoj kab sib tov sab laug tom qab cov kua dawb nyob rau hauv cov dej khov thaum muaj qhov kub nyob hauv qab cov taw tes khov.
Cov khoom siv khov kho siv nyob rau sab nraud phab ntsa rwb thaiv tsev yog qhov feem ntau yog qhov hloov pauv ntawm cov cement, thiab kev txhim kho thaum ntxov yog qeeb. Yog tias nws ntsib khov txias, nws yuav tsis ntseeg ua tej yam tsis zoo. Thaum cov dej dawb uas tseem tsis tau hydrated nyob rau hauv cov xis mas kab laum freezes thiab nthuav dav, nws yuav ua rau kev puas tsuaj rau cov qauv tshuaj khib uas tseem tsis tau tsim lub zog txaus. Qhov tshwm sim kawg yog qhov ua haujlwm catch ua tsis muaj zog.
Nws raug nquahu kom nruj rau kev ua haujlwm tshwj xeeb tau hais hauv jgj 144-2004 txheem. Thaum qhov kub tshaj plaws yog qis dua 5 degrees Celsius, kev tsim kho ntawm cov tshuaj tua kab mob xis nyob rau sab nrauv phab ntsa yuav tsum nres tam sim ntawd. Rau sab nrauv phab rwb thaiv tsev phab ntsa uas tau raug kev txom nyem ua kev puas tsuaj rau kev kho kom tsim nyog rau kev kho, nyob ntawm kev puas tsuaj. Yog tias qhov kev puas tsuaj loj, nws raug nquahu kom nws los kua muag thiab rov tsim kho nws.
