steel qauv coatings xim

Hlau yog ib yam khoom siv hauv tsev tsis muaj hluav taws kub, nws muaj seismic, dabtsi yog khoov thiab lwm yam ntxwv. Hauv kev siv tswv yim, cov hlau tsis tuaj yeem tsuas yog nce lub peev xwm ntawm lub tsev, tab sis kuj ua tau raws li cov kev xav tau ntawm kev tsim qauv zoo nkauj ntawm kev tsim vaj tsev. Nws kuj zam qhov tsis xws luag uas cov khoom siv hauv tsev xws li pob zeb tsis tuaj yeem khoov thiab ncab. Yog li ntawd, steel tau txais kev pom zoo los ntawm kev tsim kho kev lag luam, ib-storey tsev, ntau-storey, skyscrapers, factories, warehouses, tos chav tsev, tawm mus thiab lwm yam steel. Yuav kom kawm tau ntawm ib leeg, kev siv ntawmsteel qauv txheej txheejthiabhlau primerxim yog qhov tseem ceeb.

Classification ntawm steel qauv txheej

Steel qauv txheej feem ntau muaj ob hom steel qauv fireproof coatings thiab steel qauv anti-corrosion txheej.
(A) steel qauv fireproof xim

1. Ultra-thin structural fireproof txheej

Ultra-thin steel qauv fireproof txheej yog hais txog cov txheej thickness li ntawm 3 hli (xws li 3 hli), cov nyhuv zoo nkauj, tuaj yeem nthuav dav ntawm qhov kub thiab txias, thiab qhov hluav taws kub tsis kam yog feem ntau nyob rau hauv 2 h ntawm cov hlau qauv fireproof txheej. Hom steel qauv hluav taws kub retardant txheej yog feem ntau hnyav-raws li system, nrog superior kev sib raug zoo zog, zoo huab cua tsis kam thiab dej tsis kam, zoo leveling, zoo zoo nkauj yam ntxwv; Thaum nws raug hluav taws kub, nws maj mam nthuav thiab foams los ua ib txheej ntom ntom ntom ntom ntom ntom ntom ntom. Cov txheej txheem hluav taws kub muaj qhov muaj zog tiv thaiv hluav taws, ncua qhov kub thiab txias ntawm cov hlau thiab tiv thaiv cov khoom hlau zoo. Kev tsim kho ntawm ultra-thin expanded steel qauv fireproof txheej yuav tsum tau txau, txhuam los yog dov, feem ntau siv nyob rau hauv qhov hluav taws kub txwv tsis pub dhau 2 h ntawm lub tsev steel qauv. Muaj ntau yam tshiab ntawm ultra-thin steel qauv fireproof coatings nrog hluav taws kub tsis kam ntawm 2 h los yog ntau tshaj, uas feem ntau yog siv polymethacrylate los yog epoxy resin nrog tshwj xeeb qauv thiab amino resin, chlorinated paraffin raws li lub hauv paus binder, nrog high polymerization degree ammonium polyphosphate, dipentaerythritol, melamine li qhov hluav taws kub retardant. Titanium dioxide, wollastonite thiab lwm yam inorganic refractory cov ntaub ntawv yog ntxiv rau 200 # hnyav roj raws li ib tug hnyav composite. Ntau lub teeb steel qauv, kab sib chaws, thiab lwm yam., siv hom tshuaj tua hluav taws no rau kev tiv thaiv hluav taws. Vim yog cov txheej txheej ultra-nyias ntawm cov txheej txheem hluav taws kub retardant, kev siv cov tuab thiab nyias steel qauv hluav taws kub retardant txheej yog txo kom tsawg, uas txo cov nqi tag nrho ntawm qhov project, thiab ua rau cov qauv hlau tau txais kev tiv thaiv hluav taws zoo, thiab kev tiv thaiv hluav taws zoo heev.

2. Hluav taws kub retardant txheej rau nyias steel qauv

Cov txheej txheem nyias-coated steel qauv fireproof txheej yog hais txog cov hlau qauv fireproof txheej uas nws txheej thickness yog ntau dua 3 hli, tsawg dua los yog sib npaug li 7 hli, muaj ib co zoo nkauj nyhuv, nthuav thiab thickens ntawm kub kub, thiab hluav taws kub txwv tsis pub dhau 2 h. Cov txheej txheem hluav taws xob zoo li no feem ntau yog tsim los ntawm cov dej-raws li polymer raws li cov khoom siv hauv paus, thiab tom qab ntawd tsim los ntawm cov txheej txheem sib xyaw ntawm cov nplaim hluav taws, cov khoom siv hluav taws xob, hluav taws kub-resistant fibers, thiab lwm yam. Rau hom fireproof txheej no, cov dej-raws li polymer yuav tsum tau xaiv yuav tsum muaj adhesion zoo, durability thiab dej tsis kam rau steel substrate. Nws kho kom zoo nkauj yog zoo dua li cov tuab fireproof coatings, inferior rau ultra-thin steel qauv fireproof coatings, thiab lub dav dav hluav taws kub txwv tsis pub dhau 2 h. Yog li ntawd, nws yog feem ntau siv nyob rau hauv steel qauv hluav taws kev tiv thaiv tej yaam num nrog tsawg tshaj li 2 h hluav taws tsis kam txwv, thiab tshuaj tsuag siv feem ntau. Nyob rau hauv ib lub sij hawm, nws nyob ib tug loj feem, tab sis nrog lub tshwm sim ntawm ultra-thin steel qauv fireproof coatings, nws cov lag luam feem tau maj hloov.

3. Thick steel qauv fireproof txheej

Thick steel qauv hluav taws kub retardant txheej yog hais txog cov txheej thickness ntau dua 7 hli, tsawg dua los yog sib npaug li 45 hli, granular nto, me me ntom, tsis tshua muaj thermal conductivity, hluav taws kub tsis kam ntawm ntau tshaj 2 h steel qauv hluav taws kub retardant txheej. Txij li thaum muaj pes tsawg leeg ntawm cov hluav taws kub retardant coatings yog feem ntau inorganic cov ntaub ntawv, nws cov hluav taws kev ua tau zoo yog ruaj khov thiab lub sij hawm siv cov nyhuv yog zoo, tab sis cov khoom ntawm nws cov xim yog loj, cov tsos ntawm cov txheej yog tsis sib xws, cuam tshuam rau tag nrho cov kev zoo nkauj ntawm lub tsev, yog li nws yog feem ntau siv rau cov yam ntxwv concealed engineering. Hom hluav taws kub retardant txheej no siv cov granular nto ntawm cov khoom nyob rau hauv qhov hluav taws kub, qhov ceev yog me me, thermal conductivity yog tsawg los yog tshav kub absorbs ntawm cov khoom nyob rau hauv lub txheej, uas ncua lub kub nce ntawm cov hlau thiab tiv thaiv cov hlau. Cov txheej txheem hluav taws xob no yog tsim los ntawm cov khoom siv tsis zoo (xws li iav dej, silica sol, aluminium phosphate, refractory cement, thiab lwm yam), ces nws yog tov nrog inorganic lightweight adiabatic aggregate cov ntaub ntawv (xws li nthuav perlite, nthuav vermiculite, hiav txwv bouldering, floating hlaws), cov khoom siv hluav taws xob, tshuaj tua hluav taws, thiab lwm yam. (xws li aluminium silicate fiber, pob zeb wool, ceramic fiber, iav fiber, thiab lwm yam.) thiab muab tub lim, thiab lwm yam, uas muaj qhov zoo ntawm cov nqi qis. Kev txau yog feem ntau siv rau hauv kev tsim kho, uas yog tsim rau sab hauv tsev thiab sab nraum zoov zais cov qauv steel nrog hluav taws kub txwv tsis pub ntau tshaj 2 h, high-rise all-steel structures thiab multi-storey factory steel structures. Piv txwv li, qhov hluav taws kub tsis kam ntawm cov kab ntawm cov vaj tse siab, cov vaj tse dav dav thiab cov vaj tse uas txhawb nqa ntau txheej kab yuav tsum ncav cuag 3h, thiab cov txheej tuab tuab yuav tsum tau siv los tiv thaiv lawv.

(2) steel qauv anticorrosive xim

Anti-corrosion txheej rau steel qauv yog ib yam tshiab ntawm anti-corrosion txheej rau steel qauv tsim los ntawm cov roj-resistant anti-corrosion txheej. Cov xim tau muab faib ua ob hom primer thiab sab saum toj xim, ntxiv rau, nws daim ntawv thov ntau dua, thiab cov xim tuaj yeem hloov kho rau ntau yam xim raws li kev xav tau. Steel qauv tiv thaiv corrosion txheej yog tsim rau cov dej phwj tuaj, dej hiav txwv, dej hauv dej, roj av, roj av, roj av, roj av thiab lwm yam tso tsheb hlau luam, roj, cov kav dej, cov kav dej, cov phiajcim, cov khoom siv hluav taws xob thiab txhua yam khoom siv tshuaj tiv thaiv corrosion, kuj tseem siv tau rau cov chaw ua vaj tse tiv thaiv corrosion.

Ua ntej, txhim kho qhov xwm txheej ntawm cov hlau: uas yog, kev kho alloy:

Ntau tus kws tshawb fawb txawv teb chaws tau kawm txog kev cuam tshuam ntawm ntau yam alloying ntsiab lus ntawm corrosion kuj ntawm steel rau seawater. Nws tau pom tias alloy steels raws li Cr, Ni, Cu, P, Si thiab lub ntiaj teb tsis tshua muaj cov khoom tiv thaiv corrosion zoo heev, thiab ntawm lub hauv paus no, cov seawater corrosion resistant steels tau tsim. Txawm li cas los xij, vim kev xav txog kev lag luam thiab thev naus laus zis, cov ntsiab lus saum toj no tsis tau siv dav hauv seawater corrosion resistant steels.

Thib ob, tsim cov txheej txheem tiv thaiv: uas yog, txheej txheej tsis yog xim hlau lossis hlau tiv thaiv txheej:

Cov hlau tiv thaiv txheej yog tsuas yog siv rau phosphating, oxidation thiab passivation kev kho mob ntawm cov hlau coated. Cov txheej txheem tiv thaiv tsis yog xim hlau feem ntau yog txheej txheej xim, yas, enamel, ntxhia roj thiab lwm yam ntawm cov hlau saum npoo los tsim cov txheej txheem tiv thaiv. Lub hom phiaj ntawm ob txheej tiv thaiv no yog cais cov khoom siv hauv paus los ntawm kev sib cuag nrog dej hiav txwv, es tsis txhob cuam tshuam nrog dej hiav txwv, yog li tsim kev tiv thaiv.
