Whakatuwheratanga

Donspray504 Ko te Whakanoho Clend Polyys, ko te kaihoko pupuhi ko te 245FA hei utu mo te HCFC-141B, e pa ana ki te Isocyanate ki te whakaputa i nga maakuku he tino mahinga, e whai ake nei,

1) pūtau pai me te whakakotahi

2) whanonga waiariki iti

3) Te ātete mura o te mura ahi

4) pai te pāmahana iti-pāmahana.

E pa ana ki nga momo miihini waiariki wera e whakamahi ana i te hangarau rehu, penei i nga ruma makariri, kohua, nui-rahi-rahi me te metal me te metape me te metope metope me etahi tohu hanga etc.
