Rau cov neeg siv khoom xav txog ASTM A588 Corten Steel rau hluav taws kub - cov khoom siv tiv thaiv (xws li cov kab teeb hauv tsev, kab, kab, cov ntoo cog), cov lus nug tseem ceeb yog seb nws puas tuaj yeem siv ncaj qha thiab yuav tsum ntsuas kev tiv thaiv hluav taws li cas. Cov lus teb luv luv yog:Tsis yog, nws tsis tuaj yeem siv ncaj qha; Cov phiaj xwm tiv thaiv hluav taws yuav tsum tau ua. Kab lus no qhia meej txog cov ntsiab lus tseem ceeb thiab cov tswv yim daws teeb meem.
1. Vim li cas ASTM A588 tsis tuaj yeem siv ncaj qha rau hluav taws kub -Cov qauv tiv thaiv
ASTM A588 cov huab cua zoo heev tsis tau txhais hais tias nws muaj hluav taws kub. Cov hlau, suav nrog Corten Steel, tau txais cov cuab yeej cuab tam tseem ceeb ntawm qhov kub thiab txias: - Ntawm 550℃(qhov kub thiab txias hauv tsev hluav taws), ASTM A588's yield zog poob qis dua 50% ntawm nws chav-tus nqi kub (Ntau dua lossis sib npaug rau 345MPa) {6} {8b1} , qhov muaj peev xwm ntawm ASTM A588 yuav luag ploj, ua rau kev puas tsuaj. Feem ntau cov kab hluav taws xob tiv thaiv yuav tsum muaj cov qauv hlau kom muaj peev xwm thauj khoom tau ntev li 60-120 feeb (piv txwv li, ASTM E119 tus qauv), uas liab qab ASTM A588 tsis tuaj yeem ua tau raws li (tsuas yog 15-20 feeb ntawm kev tiv thaiv hluav taws).
2. Cov Kev Tiv Thaiv Hluav Taws Tseem Ceeb rau ASTM A588
Intumescent Fire-Resistant Txheej (Feem ntau): Siv dej-raws li los yog hnyav-raws li intumescent txheej (qhuav zaj duab xis thickness 0.8-2.5mm, nyob ntawm seb yuav tsum tau tua hluav taws lub sij hawm). Thaum raug hluav taws kub, cov txheej nthuav dav los tsim cov txheej txheem carbonaceous tuab, ncua kev hloov mus rau cov hlau. Qhov kev ntsuas no tswj cov xim xeb ntawm ASTM A588 thaum tsis muaj hluav taws thiab ua tau raws li 60-120 feeb ntawm kev tiv thaiv hluav taws (ASTM E119).
Qhob Encasement: Rau cov khoom hnyav-cov haujlwm ua haujlwm (piv txwv li, choj piers, cov kab kev lag luam loj), ntim ASTM A588 nrog 50-100mm tuab reinforced pob zeb. Qhob lub siab thermal inertia zoo insulates cua sov, muab hluav taws kub tiv taus ntau tshaj 120 feeb. Txoj kev no yog ruaj tab sis nce qhov hnyav ntawm cov qauv.
Hluav taws kub-Resistant Board Enclosure: Siv cov calcium silicate los yog gypsum hluav taws-cov boards tiv taus los kaw qhov ASTM A588 cov khoom siv. Cov laug cam tsim cov kab noj hniav kaw, ua tiav 60-90 feeb ntawm hluav taws kub. Qhov kev ntsuas no yog ib qho yooj yim rau nruab thiab haum rau cov teeb pom kev zoo (piv txwv li, lub tsev ob kab teeb).
3. Cov lus pom zoo rau kev siv
Match Measures rau Hluav Taws Kub Resistance Requirement: Rau 60-feeb tiv thaiv hluav taws (feem ntau nyob rau hauv cov tsev), xaiv intumescent coatings (1.0-1.5mm tuab); rau 120-feeb hluav taws kub tsis kam (cov nroj tsuag kev lag luam, cov tsev siab siab), siv cov pob zeb ua pob zeb los yog cov coatings thickened intumescent (2.0-2.5mm).
Koom tes tiv thaiv hluav taws thiab huab cua tiv thaiv: Thaum siv hluav taws kub- cov txheej tiv thaiv, xyuas kom cov txheej txheem sib xws nrog ASTM A588's xeb txheej. Rau cov qauv sab nraum zoov, xaiv cov huab cua- tiv thaiv intumescent txheej (nrog UV stabilizers) kom tsis txhob muaj txheej laus thiab tev.
Ua raws li Cov Cai Hauv Zos: Paub meej tias yuav tsum muaj lub sijhawm tiv thaiv hluav taws thiab siv tau cov kev tiv thaiv raws li cov qauv hauv zos (xws li ASTM E119 hauv Asmeskas, EN 13381 hauv EU) kom ntseeg tau tias ua raws.
Hauv cov ntsiab lus, ASTM A588 Corten Steel tsis tuaj yeem siv ncaj qha rau hluav taws kub - cov khoom siv tiv thaiv vim qhov tsis zoo siab - qhov kub thiab txias. Xaiv cov kev tiv thaiv hluav taws uas tsim nyog (cov txheej txheem inumescent, pob zeb encasement, thiab lwm yam) raws li cov kev cai tiv thaiv hluav taws thiab daim ntawv thov scenarios ua kom ob qho tib si cov qauv kev nyab xeeb hluav taws thiab ASTM A588 lub sijhawm ntev - huab cua tsis kam.
