Donfoam 822PIR HCFC-141B chawo sanganisa polyols kuti kuramba PIR misa furo
NHANGANYAYA
DonFoam 822 / PIR rudzi sanganisa polyols vane hcfc-141b furo mumiriri, pamwe polyol sezvo huru mbishi zvinhu, hwakakanyiwa inokosha upiyona mumiririri, yakakodzera mudziye kuvakwa, zvokufambisa, goko nezvimwe zvinogadzirwa .This zvinhu zviri zvikuru dzakabudirira nokuti kuramba mutsetse isu takanzwa pamurayiro polyurethane chigadzirwa yakagadzirwa zvokuverengera pamwe isocyanate ane zvinotevera zvazvakanakira:
1. Foam ane simba yunifomu ndeiya yakaita nokugarika zvose kumativi
2. furo zvigadzirwa inogona racherwa zvitarisiko zvakasiyana maererano zvinodiwa chigadzirwa
3. Excellent kumbogadzirwa kuti mudziye waivako
