1. Cov khoom no yog anatural high-refractory inorganic khoomraws li cov khoom tseem ceeb.Nws yog ua los ntawm cov hluav taws kub kub-retardant tiv thaiv txheej nrog lub siab tiv thaiv hluav taws tsis pub dhau 3 teev lossis ntau dua nrog cov ntaub ntawv polymer.
2, cov khoom yog ob-tivthaiv nws tus kheej ziab txheej, yooj yim rau kev tsim, tuaj yeem txau, smeared.
3. Cov txheej txheem ntawm cov khoom no yogqhuav sai.Tom qab 27 hnub ntawm kev kho, cov txheej yog qhuav thiab resistant rau khob, thiab muaj kev co zoo heev thiab huab cua tsis kam.
4. Cov khoom notsis muaj benzene thiab asbestos cov ntaub ntawv.Nws tsis tso cov tshuaj lom thiab teeb meem thaum raug kub thiab tsis muaj teeb meem rau tib neeg lub cev.Cov thermal conductivity tsawg, thiab qhov hluav taws kub tsis kam rau cov hlau yog ntau tshaj 3 teev.
1. Ua ntej kev tsim kho, qhov saum npoo ntawm cov qauv hlau yuav tsum tau dedusted, ntxuav thiab derusted kiag li.Tom qab ntawd siv cov tshuaj tiv thaiv xeb raws li qhov yuav tsum tau ua, lub thickness ntawm anti-xeb xim yuav tsum yog 0.1-0.15mm.Anti-xeb xim feem ntau yog ua los ntawm liab dan los yog epoxy zinc-nplua nuj xim los tiv thaiv xeb.Tom qab hnav cov xim tiv thaiv xeb, nws yog siv rau NH-II thiab WH-II sab nraum zoov tuab steel qauv fireproof txheej siv.
2. Cov hmoov qhuav qhuav cov khoom tseem ceeb ntawm ob lub ntsiab xim thiab cov khoom tshwj xeeb yog sib xyaw nrog dej ntawm qhov sib piv ntawm 1: 0.1-0.2: 0.8-1, thiab tom qab ntawd sib tov sib xyaw, thiab tom qab ntawd kev tsim kho tuaj yeem nqa tawm.
3. Ua ntej kev tsim kho, cov primer yuav txhuam los yog txau rau ntawm qhov chaw ntawm substrate rau 1-2 zaug.Tom qab qhov saum npoo qhuav lawm, txheej txheej fireproof tuaj yeem siv tau.Kev tsim kho tuaj yeem txau lossis smeared.Rau thawj 1-3 zaug, lub thickness ntawm txheej yuav tsum yog 2-3 hli, thiab lub thickness ntawm txhua txheej yuav yog li 5-6 hli kom txog rau thaum lub thickness tau mus txog.Lub sijhawm nruab nrab ntawm txhua qhov kev tsim kho yog 12-18 teev.Cov cua ncig yuav tsum tau khaws cia ntawm qhov chaw tsim kho.Cua ceev tsis tshaj 5m / s.Nws tsis haum rau kev tsim kho thaum condensation tshwm sim nyob rau saum npoo ntawm cov qauv steel.
4. Rau sab nraum zoov lossis hauv corrosive gas ib puag ncig, cov txheej txheem tiv thaiv ntawm cov txheej yuav tsum tau kho.Cov txheej tiv thaiv yog muab los ntawm lub tuam txhab.Lub thickness ntawm lub overlay yog hais txog 0.25mm.

Txau: tsis yog cua txau lossis cua txau.Kev kub siab tsis siv roj txau.
Txhuam / yob txheej: yuav tsum ua tiav cov txheej txheem qhuav zaj duab xis tuab.
