Dab tsi ntawm Kev Ntsuas Hluav Taws Xob Tau Ua Rau Hluav Taws Xob Magnesium Oxide Subfloor Board
Muaj ntau ntau hom kev ntsuas hluav taws uas tau ua rau ntawm Fireproof Mgo Wallboard, suav nrog:
Kev ntsuas hluav taws kub
Qhov no suav nrog kev nkag mus rau phab ntsa kom tswj tau qhov hluav taws kub los txiav txim siab nws lub peev xwm tiv thaiv hluav taws thiab tiv thaiv kev sib kis ntawm cov nplaim taws. Lub phab ntsa tuaj yeem raug sim rau lub sijhawm tshwj xeeb, xws li 30 feeb, 60 feeb, lossis ntev dua, txhawm rau ntsuas nws qhov ntsuas hluav taws kub.
Kev Ntsuas Nplaim
Qhov kev ntsuam xyuas no ntsuas tus nqi ntawm cov nplaim taws kis mus rau qhov chaw ntawm phab ntsa. Nws pab txiav txim siab txog cov khoom muaj peev xwm los txwv kev sib kis ntawm hluav taws thiab tiv thaiv nws los ntawm engulfing ib cheeb tsam loj.
Kev Ntsuas Kev Ntsuas Hluav Taws Xob
Qhov kev ntsuam xyuas no ntsuas cov pa taws tawm ntawm phab ntsa thaum raug hluav taws. Nws yog ib qho tseem ceeb vim tias kev nqus pa tuaj yeem ua rau muaj kev phom sij loj thaum muaj hluav taws kub.
Kev kuaj toxicity
Qhov no suav nrog kev ntsuas qhov tso tawm cov pa phem lossis tshuaj lom neeg los ntawm phab ntsa phab ntsa thaum raug kub hnyiab. Cov pa roj carbon monoxide tawm thaum hluav taws tuaj yeem ua rau muaj kev phom sij rau cov neeg nyob hauv.
Hluav taws kub Resistant Magnesium Oxide Subfloor Board
Hauv pem teb slab / cushion yuav tsum tiaj tus (yuam kev Tsawg dua lossis sib npaug li 3 hli / 2m), qhuav (cov ntsiab lus noo noo<8%), clean, oil-free, and free of loose impurities; if the substrate is damp (e.g., basement), apply a layer of cement-based permeable crystalline waterproof coating first, and make 50mm arc treatments at internal and external corners.
① Tso cov kev taw qhia: Perpendicular mus rau nteg cov kev taw qhia ntawm cov av pem teb kom tsis txhob muaj kev ntxhov siab concentration;
② Kev txwv qhov sib txawv: Cia qhov sib txawv ntawm 2-3 hli ntawm cov laug cam thiab qhov sib txawv ntawm 8-10mm rau phab ntsa (kom nqus tau qhov kub thiab txias deformation);
③ Txhim kho txoj kev: Kho nrog 316 stainless hlau tus kheej -tapping screws, ntsia hlau sib nrug 300 × 300mm, countersink ntsia hlau taub hau 1-2mm hauv qab ntawm qhov chaw (kom tsis txhob muaj kev sib tw), thiab qhov kev ncua deb ntawm cov ntsia hlau mus rau board ntug ntau dua los yog sib npaug li 15mm (kom tiv thaiv ntug chipping).
① Ntoo flooring / SPC flooring: Ncaj nraim nteg cov dej noo- pov thawj lev ntawm MgO puag hauv pem teb, tom qab ntawd ua qhov ntsuas phoo;
② Ceramic vuas: Tag nrho - nplaum installation nrog cov nplais nplaum, tsis tas yuav tsum muaj txheej txheej ntxiv;
③ Cov chaw ntub dej: Tom qab tso lub hauv paus hauv pem teb, sau cov pob qij txha nrog nruab nrab sealant los txhim kho cov dej tsis sib haum.
Kev tsim kho kub yuav tsum tswj ntawm 10-35 degree, thiab huab cua av noo<75%; avoid construction in rainy days, high-temperature exposure, or low-temperature freezing environments; after the boards are delivered to the construction site, they should be placed for more than 24 hours to adapt to the ambient temperature and humidity before laying.
