Rau cov neeg siv khoom xav txog SPA-C Corten Steel (JIS G 3125 tus qauv) rau hluav taws kub- cov khoom siv tiv thaiv (xws li, cov kab teeb hauv tsev, cov nroj tsuag cog), cov lus nug tseem ceeb yog seb nws puas tuaj yeem siv ncaj qha thiab cov txheej txheem tiv thaiv hluav taws puas sib haum. Lub ntsiab lus teb yog:Tsis yog, nws tsis tuaj yeem siv ncaj qha; yuav tsum muaj cov txheej txheem tiv thaiv hluav taws. Kab lus no qhia meej txog cov laj thawj hauv qab no, cov txheej txheem sib xws, thiab cov txheej txheem siv tswv yim.
1. Vim li cas SPA-C tsis tuaj yeem siv ncaj qha rau hluav taws-Cov qauv tiv thaiv
SPA-C cov huab cua tiv thaiv zoo tsis sib npaug rau hluav taws kub. Zoo li tag nrho cov hlau, nws cov khoom siv kho tshuab degrade sharply ntawm qhov kub thiab txias, ua tsis tau raws li qhov yuav tsum tau muaj hluav taws kub:
Ntawm 550℃(qhov kub thiab txias hauv tsev hluav taws xob), SPA-C's yield zog poob qis dua 50% ntawm nws chav-tus nqi kub (Ntau dua lossis sib npaug rau 345MPa ib JIS G 3125).
Ntawm 600 degree, nws cov load-cov kabmob muaj peev xwm yuav luag ploj, ua rau muaj kev sib tsoo. Feem ntau cov lej hluav taws kub (xws li ASTM E119, EN 13381) xav tau cov qauv hlau kom muaj peev xwm thauj khoom -cov kabmob muaj peev xwm rau 60-120 feeb, uas liab qab SPA-C tsis tuaj yeem ua tiav (tsuas yog 15-20 feeb ntawm kev tiv thaiv hluav taws).
2. Compatible Fire Protection Coatings for SPA-C
Cov txheej txheej tiv thaiv hluav taws uas tau xaiv yuav tsum tsis yog tsuas yog muab cov rwb thaiv tsev thermal xwb tab sis kuj yog sib xws nrog SPA-C's tus kheej- txheej tiv thaiv xeb (xws li txheej txheej tev lossis tshuaj tiv thaiv). Pom zoo tau tshaj txheej muaj xws li:
Intumescent Fire-Resistant Coatings (Xav tau): Dej-raws li lossis hnyav-raws li intumescent txheej (xws li, acrylic intumescent txheej) yog qhov tsim nyog tshaj. Thaum raug hluav taws kub, lawv nthuav dav los ua ib txheej txheej carbonaceous rwb thaiv tsev, ua kom kub hloov mus rau SPA-C. Cov ntsiab lus tseem ceeb: ① Dry film thickness: 0.8-2.5mm (kho raws li qhov yuav tsum tau muaj hluav taws kub lub sij hawm: 60min rau 1.0-1.5mm, 120min rau 2.0-2.5mm). ② Compatibility: Xaiv cov coatings uas sau tias "tshaj nrog Corten Steel" los xyuas kom meej adhesion rau cov xeb txheej. Lawv tuav SPA-C lub ntuj pom thaum tsis muaj hluav taws, zoo tagnrho rau kev siv architectural.
Epoxy Fire-Resistant Mortar (Rau Heavy-Cov Qauv Ua Haujlwm): Rau cov kab cog qoob loo los yog choj piers uas xav tau kev ua haujlwm siab, epoxy hluav taws kub -cov tshuaj tiv thaiv raug pom zoo. Nws muaj qhov zoo adhesion thiab cuam tshuam tsis kam, ua rau cov txheej txheem rwb thaiv tsev nyuaj (thickness 15-}30mm) uas muab 60-120 feeb ntawm hluav taws kub. Nws yog sib xws nrog SPA-C thiab resistant rau hnyav industrial puag ncig.
Zam cov txheej txheem tsis sib xws: Tsis txhob siv roj-raws li alkyd coatings los yog tsawg-cov chlorinated roj hmab coatings zoo-lawv muaj adhesion tsis zoo rau SPA-C's xeb txheej thiab tej zaum yuav tev tawm nyob rau hauv qhov kub thiab txias, poob kev tiv thaiv hluav taws.
3. Cov lus pom zoo rau kev siv
Ua ntej- Txheej Txheej Txheej Txheej: Ntxuav lub SPA-C nto kom tshem tawm cov xeb, plua plav, thiab roj stains. Rau kev txhim kho tshiab SPA-C, tos 1-2 lub hlis rau cov txheej txheem xeb thawj zaug (los yog siv cov xuab zeb blasting los txhim kho qhov roughness Ra 3.2-6.3μm) txhawm rau txhim kho txheej adhesion.
Coating Application & Curing: Siv cov coatings nyob rau hauv qhov chaw qhuav, zoo - qhov cua qhov chaw (kub 5-35 degree, txheeb ze av noo tsawg dua lossis sib npaug li 85%). Ua raws li cov chaw tsim khoom cov lus qhia rau lub sijhawm kho (tsis txhob raug nag los nag lossis huab cua siab). Ua cov thickness kuaj tom qab kho kom zoo raws li qhov yuav tsum tau ua.
Ua raws li Cov Cai Hauv Zos: Paub meej tias yuav tsum muaj lub sijhawm tiv thaiv hluav taws thiab cov txheej txheem txheej txheem raws li cov cai hauv zos (xws li ASTM E119 rau North America, EN 13381 rau Tebchaws Europe) kom ntseeg tau tias txoj haujlwm ua raws.
Hauv cov ntsiab lus, SPA-C Corten Steel tsis tuaj yeem siv ncaj qha rau hluav taws- cov khoom siv hluav taws xob tsis zoo vim qhov ua haujlwm tsis zoo - qhov kub thiab txias. Xaiv cov hluav taws kub zoo sib xws- cov coatings resistant los yog hluav taws kub epoxy- mortar resistant, ua ke nrog kev npaj saum npoo kom zoo, ua kom muaj kev nyab xeeb ntawm hluav taws thiab SPA-C's ntev - huab cua tsis kam.
