Cov xim yog txau rau saum npoo ntawm cov qauv steel, feem ntau plays lub luag haujlwm zoo nkauj.Thaum hluav taws kub, nws nthuav thiab thickens thiab carbonizes los ua ib tugnon-flammable sponge zoo li carbon txheej, yog li txhim kho qhov hluav taws kub tsis kam ntawm cov qauv steel rauntau tshaj 2.5 teev, yeej lub sijhawm tua hluav taws thiab tiv thaiv zoo.Cov qauv hlau muaj kev tiv thaiv los ntawm hluav taws.
1, silicone-acrylic emulsion thiab chlorine ib nrab emulsion tov, tuaj yeem txhim kho qhovdej tsis kamthiabhluav taws kubntawm sab hauv tsev nyias steel qauv hluav taws kub retardant txheej, tab sis ua ib tug zoo compatibility xeem los tiv thaiv qhov tshwm sim ntawm demulsification.
2, qhov sib ntxiv ntawm inorganic poov tshuaj silicate tuaj yeem txhim kho lub compactness ntawm txheej zaj duab xis, yog li txhim kho cov dej tsis kam thiab hluav taws kub tsis kam ntawm txheej zaj duab xis, tab sis yuav tsum tau muab sib xyaw ua ntej nrog cov khoom siv hauv paus thaum ntxiv, thiab tom qab ntawd maj mam ntxiv mus rau qhov ua ntej. -slurry los tiv thaiv polyphosphoric acid Lub rooj tsavxwm yog tsim rau hauv coarse hais.
3, Hydroxypropyl methylcellulose thiab bentonite tuaj yeem ua tau zoo muab cov dej uas yuav tsum tau tuav thiab thixotropic tus nqi ntawm lub cev, txhim kho qhov pib qhuav tawg, thiabyooj yim rau tshuaj tsuag, khawb txheej siv.
Siv rau ntawm cov qauv steel ntawm lub tsev tsis pub dhau 2.5 teev ntawm qhov hluav taws kub tsis kam, xws libeams, slabs, ru tsev load-bearing cov tswv cuab nyob rau hauv ib hom ntawm lub tsev;kab, kab, slabs thiabntau lub teeb steel kab teebthiab daim phiaj nyob rau hauv hom thib ob ntawm cov tsev.

Kev tsim kho ib puag ncig:
Ua ntej txheej txheem kev tsim kho thiab txheej txheej kom qhuav thiab kho, qhov kub thiab txias yuav tsum tau khaws cia ntawm 5-40 ° C, txheeb ze av noo> 90%, qhov cua qhov chaw yuav tsum zoo.
Nws tuaj yeem siv tau los ntawm kev txau, txhuam, cov menyuam txheej, thiab lwm yam. Tom qab cov txheej txheem siv rau hauv daim ntawv thov dhau los yog qhov pib qhuav thiab khov kho, nws yog txau ib zaug ntxiv, feem ntau ntawm 8-24 teev, kom txog rau thaum lub thickness xav tau.
1. Kev tsim kho ntawm cov txheej txheem hluav taws xob, vim tias cov txheej txheem hluav taws xob feem ntau yog ntxhib, nws raug nquahu kom siv rab phom tua tus kheej hnyav nrog kev tswj tsis siv neeg siab ntawm 0.4-0.6Mpa;rau kev kho ib nrab thiab kev tsim kho me me, nws tuaj yeem txhuam, txau lossis dov, siv ib lossis ntau txoj hauv kev yooj yim los tsim.Cov tshuaj tsuag nozzle rau cov tshuaj tsuag primer kuj tseem siv tau rau cov tshuaj tsuag txheej thaum cov kab uas kho tau yog 1-3 hli.Yog tias pleev xim rau manually, tus naj npawb ntawm txhuam hniav yuav tsum tau nce ntxiv.
2. Qhov tuab ntawm txhua qhov hla yuav tsum tsis pub tshaj 0.5 hli thaum txau, thiab nws yuav tsum tau txau ib zaug txhua 8 teev nyob rau hauv huab cua zoo.Thaum txau ib lub tsho ntawm cov xim, nws yuav tsum tau qhuav ua ntej cov tshuaj tsuag.Lub thickness ntawm txhua kab ntawm phau ntawv txau yog nyias, thiab tus naj npawb ntawm lem yog ntsuas raws li thickness.
3. Raws li lub sij hawm refractory yuav tsum tau ntawm cov coated steel qauv, tus coj txheej thickness yog txiav txim.Theoretical txheej noj ib 1 square meter ib 1 square meter ntawm txheej yog 1-1.5kg.
4. Tom qab txau cov hluav taws kub retardant txheej, nws raug nquahu kom siv 1-2 zaug ntawm acrylic los yog polyurethane anticorrosive topcoat kom ntseeg tau tias cov xim zaj duab xis yog du thiab du thiab muaj cov nyhuv zoo nkauj.
Txhua qhov chaw yuav tsum huv, qhuav thiab tsis muaj kab mob.Ua ntej pleev xim, yuav tsum tau soj ntsuam thiab kho raws li tus qauv ntawm ISO8504: 2000.
Lub hauv paus kub tsis tsawg tshaj 0 ℃, thiab tsawg kawg yog saum huab cua dew point kub 3 ℃, tus txheeb ze av noo ntawm 85% (kub thiab txheeb ze av noo yuav tsum tau ntsuas ze ntawm lub hauv paus khoom), pos huab, nag, daus, cua thiab nag yog txwv tsis pub tsim kho.
Alkyd primer los yog epoxy zinc nplua nuj primer, epoxy primer, thiab topcoat yuav alkyd topcoat, enamel, acrylic topcoat, acrylic enamel thiab hais txog.
