Yog xim hlau phajsandwich vaj huam sib luagfireproof?
Xim steel phaj yog cov phaj sib xyaw uas siv cov xim coated steel phaj ua cov khoom siv saum npoo thiab polystyrene ua npuas ncauj ua cov khoom tseem ceeb. Nws yog lub teeb yuag thiab muaj kev ua haujlwm zoo seismic (qhov hnyav tsuas yog 1/4 ~ 1/5 ntawm lwm cov ntawv organic), tsis muaj dej thiab tsis muaj dej. Nws muaj qhov zoo xws li ua npauj pov thawj thiab yooj yim thiab ceev rau nruab.
Cov neeg siv nyiam nws vim nws ntau qhov zoo. Txawm li cas los xij, feem ntau ntawm ntau yam xim-coated coil cov khoom tam sim no muag hauv khw tsis qhia lawv qhov kev ua tau zoo ntawm kev sib xyaw lossis tsis tiav, uas coj qee yam kev phom sij thiab teeb meem rau cov neeg siv. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum nkag siab txog qee qhov kev paub txog txhawm rau ua qhov kev xaiv raug. thiab siv.
1. Raws li GB8624-97 "Combustibility Classification of Building Materials and Products" standard, muaj peb hom: Class A non-combustible materials, Class B1 flame-retardant materials and Class B2 combustible materials. Raws li qhov yuav tsum tau ua, cov vaj huam sib luag zoo nkauj rau cov tsev tuaj yeem muab faib ua peb pawg hauv qab no:
(1) nplaim retardant hniav vaj huam sib luag:
Piv txwv li, txheej txheej txheej ntawm pob zeb wool thermal rwb thaiv tsev cov ntaub ntawv siv ultra-nyias silicone-acrylic resin zaj duab xis uas tsim los ntawm inorganic fiber txau tshuab raws li cov txheej txheem tiv thaiv cov nplaim hluav taws-retardant hniav panels. Cov khoom tsim los ntawm cov khoom siv no yuav tsis tsim cov nplaim taws hauv qhov kev tsim kho ib txwm muaj thiab muaj hluav taws kub zoo. Lawv tsim nyog rau kev kho kom zoo nkauj sab hauv ntawm cov tsev nrog kev tiv thaiv hluav taws thiab cov phiaj xwm qab nthab hauv cov chaw pej xeem.
(2) Non-flame retardant hniav panels:
(Nrog rau cov PVC yas-coated zoo tib yam thiab txhuas ntawv ci-coated) Cov khoom zoo li no muaj qhov kub thiab txias tsis kam. Feem ntau siv rau lub hauv paus ib feem ntawm phab ntsa tej yaam num thiab qab nthab tej yaam num nyob rau hauv pej xeem qhov chaw tsis muaj tshwj xeeb yuav tsum tau. Piv txwv li, cov kab hauv qab hauv cov khw muag khoom lag luam thiab cov kab hauv qab hauv cov chav sib tham hauv chav ua haujlwm txhua qhov poob hauv pawg no.
(3) Flammable hniav panels:
Cov khoom no tsis tiv taus qhov kub thiab txias, nws yooj yim rau kev laus, ua nkig, tawg thiab deforms, thiab muaj lub neej ua haujlwm luv. Nws feem ntau yog siv los ua ib ntus sab nrauv phab ntsa npog lossis sab hauv phab ntsa vaj huam sib luag ntawm ib qho yooj yim awning.
2. Raws li tus qauv GB50203-2002, muaj qhov sib txawv qhov ntsuas qhov xav tau rau cov xim hlau phaj nrog cov thickness sib txawv. Qhov tso cai sib txawv ntawm thickness yog teev nyob rau hauv cov lus hauv qab no
3. Raws li cov kev cai ntawm lub teb chaws tus qauv, thaum lub nominal loj ntawm cov xim hlau phaj siab tshaj los yog sib npaug zos rau mm, nws muaj peev xwm hu ua ib tug galvanized hlau embossed phab ntsa kaum protector yog hais tias nws ua tau raws li tsawg kawg yog ib tug ntawm cov nram qab no tej yam kev mob.
a.1 Galvanizing amount ≥120g/m2; b.2 Edge protection width ≤80 mm; c.3 Tolerance ±3%; d.4 Bending strength >400N/m2.
