China Donfoam 812 HCFC-141B m'munsi ankaphatikiza polyols kwa chipika thovu wopanga ndi katundu |INOV

Donfoam 812 HCFC-141B maziko osakaniza polyols kwa chipika thovu

Donfoam 812 HCFC-141B base blend polyols for block thovu Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Donfoam 812 amaphatikiza ma polyether polyols omwe amagwiritsidwa ntchito popanga thovu la PUR block.Chithovucho chimakhala ndi cell yunifolomu, kutsika kwamafuta otsika, magwiridwe antchito otenthetsera mafuta ndiabwino, magwiridwe antchito amoto ndi abwino, kutentha pang'ono palibe kung'ung'udza etc.

Amagwiritsidwa ntchito kwambiri popanga mitundu yonse ya ntchito zotchinjiriza monga: kumanga khoma lakunja, kusungirako kuzizira, akasinja, mapaipi akulu etc.
