Donpipe 322 HCFC-141b chawo sanganisa polyols kuti Mapaipi deko
I NTRODUCTION
DonPipe 322 rudzi sanganisa polyols vane hcfc-141b sezvo inopupuma mumiriri, vachitora polyol sezvo huru mbishi zvinhu, vachisanganisa ane hwebetsero inokosha. Izvi zvinhu akakodzera rokunze kumbogadzirwa kuti mudziye anoshongwa iyo inoshandiswa mvura, mafuta uye gasi mapaipi isu takanzwa pamurayiro polyurethane chigadzirwa yakagadzirwa zvokuverengera pamwe isocyanate ane zvinotevera zvazvakanakira:
- zvakanaka compressive simba uye ndeiya yakaita pakusimba
- yakakwirira pedyo-sero mwero uye zvakanaka isapinda chaitwa
- zvakanaka kuputira waivako
