ʻO Donfoam 822PIR HCFC-141B kumu hoʻohui i nā polyols no ka pahu pahu PIR mau.
OLELO HOOLAHA
ʻO DonFoam 822 / PIR kahiʻano polyols hui pū me ka hcfc-141b foaming agent, me ka polyol ma keʻano he kumu waiwai nui, i hui pūʻia me ka mea kōkua kūikawā, kūpono no ka hoʻouluʻana i ke kūkuluʻana, ka laweʻana, ka pūpū a me nā huahana'ē aʻe. no ka laina hoʻomau . ʻO ka huahana polyurethane i hoʻomākaukau ʻia ma ka hana ʻana me ka isocyanate nā mea maikaʻi aʻe:
1. Loaʻa ka ikaika like ʻole o ka foam a me ke kūpaʻa dimensional ma nā ʻaoʻao āpau
2. Hiki keʻokiʻokiʻia nā huahana foam i nāʻano likeʻole e like me nā koi o ka huahana
3. Hana maikaʻi loa i ka hoʻoheheʻe wela
