TAW qHIA
DonSpray 501 yog ib tug ob-lub Cheebtsam, tsuag-hos, qhib-cell polyurethane ua npuas ncauj system. Cov khoom no yog siab dej-cua tshuab
ua npuas ncauj system nrog zoo ua yeeb yam ntawm cov uas tsis muaj kev ceev (8 ~ 10kg / m3), qhib ntawm tes thiab hluav taws kuj Class B3.
Thaum lub sij hawm cov tshuaj tsuag txheej txheem nyob rau hauv qhov chaw, lub ua pa me me qhib cell uas muaj cov huab cua, tsis muaj ua tshuaj lom roj ua kom puas lub Nws
txheej (tsoos blowing neeg sawv cev: F-11, HCFC-141B), uas yog cheeb tsam phooj ywg, tsawg-carbon tshiab kev tsim kho cov ntaub ntawv.
Nrog heev kev ua tau zoo ntawm thermal rwb thaiv tsev, dej & vapor teeb meem, huab cua teeb meem, suab haum, PU ua npuas ncauj peev xwm muab peb ib tug
quieter, ntau zog txuag vaj tse ua peb mus rau ib tug noj qab haus huv lub neej.
