Qhov tseeb, muaj ntau txoj kev rwb thaiv tsev rau cov kav dej los tiv thaiv corrosion, nrog rau cov txheej txheem rwb thaiv tsev, qhwv cov ntaub ntawv tiv thaiv corrosion nyob ib ncig ntawm cov kav dej los tiv thaiv corrosion, thiab sau thiab insulating anti-corrosion steel kav. Tshwj xeeb, lawv yog:
1. Anti-corrosion steel kav yog insulated los ntawm kev siv cov cua sov-insulating txheej, uas yog: siv nthuav perlite, nthuav qag pob zeb, asbestos hmoov, asbestos fiber, diatomite clinker thiab lwm yam unshaped heat-insulating cov ntaub ntawv, thiab ces ntxiv cement, dej iav. , refractory binder (xws li av nplaum) los yog coagulant (xws li sodium fluorosilicate), tom qab ntawd ntxiv dej rau hauv ib qho kev faib ua feem thiab sib tov sib npaug los tsim cov slurry, los yog cov ntaub ntawv rwb thaiv tsev no tuaj yeem raug rau ntawm tes los yog coated ntawm cov kav dej los tiv thaiv corrosion. cov cuab yeej, txoj kev rwb thaiv tsev ntawm kev tiv thaiv corrosion steel kav kuj hu ua txheej rwb thaiv tsev.
2. Anti-corrosion steel kav yog insulated los ntawm wrapping insulating cov ntaub ntawv, uas yog: ncaj qha qhwv nrog insulating cov ntaub ntawv xws li slag xav, iav ntaub plaub, straw hlua, asbestos hlua los yog paj rwb daim kab xev, yog li ntawd tsis tas yuav txhawj txog cov anti-corrosion steel yeeb nkab tau khov thiab ruptured. Tsis cuam tshuam rau kev siv cov kav dej los tiv thaiv corrosion.
3. Cov yeeb nkab los tiv thaiv corrosion yog ntim nrog cov khoom siv rwb thaiv tsev, uas yog, thaum cov khoom siv rwb thaiv tsev yog cov khoom thaiv, rwb thaiv tsev filling kuj tuaj yeem nqa tawm; Txawm li cas los xij, thaum lub sij hawm tsim kho, lub nplhaib txhawb nqa lub nplhaib yog tsau rau ntawm cov yeeb nkab phab ntsa, thiab nws cov tuab yog txawv ntawm cov rwb thaiv tsev Cov txheej txheem yog tib yam, thiab tom qab ntawd lub nplhaib txhawb nqa yog qhwv nrog hlau, txhuas lossis hlau mesh, thiab tom qab ntawd insulated nrog thermal rwb thaiv tsev cov ntaub ntawv; cov khoom yog sau; Cov txheej txheem filling kuj tseem tuaj yeem siv nruj arc-shaped blocks ua los ntawm cov ntaub ntawv prefabricated ntxeem tau raws li cov qauv kev txhawb nqa, nrog qhov sib nrug ntawm li 900 hli, raws li qhov ntev ntawm cov yeeb nkab rwb thaiv tsev txheej, txiav lub tiaj tus braided barbed hlau mesh, tshuab lub winding tshuab rau hauv ib lub voj voog, ua rau cov ntaub plaub slag npog lub nplhaib txhawb nqa, thiab tom qab ntawd sau cov txheej txheem rwb thaiv tsev nrog lub plhaub hlau tiv thaiv.
4. Tsis tas li ntawd, peb kuj tseem tuaj yeem siv cov khoom siv hluav taws xob prefabricated los tiv thaiv corrosion steel kav los tuav cov rwb thaiv tsev. Cov khoom tseem ceeb ntawm prefabricated rwb thaiv tsev cov khoom yog ua npuas ncauj, asbestos, diatomite, slag ntaub plaub, iav ntaub plaub, pob zeb ntaub plaub, nthuav perlite, thiab nthuav vermiculite, calcium silicate, thiab lwm yam .; prefabricated yeeb nkab rwb thaiv tsev qauv, feem ntau nrog ib txoj kab uas hla ntawm DN Tsawg dua los yog sib npaug li 80 mm, siv lub semi-circular plhaub, xws li DN Ntau tshaj los yog sib npaug rau 100 hli, siv cov vuas-zoo li tus kiv cua (arc vuas) los yog cov vuas trapezoidal.
