IOLELO HOOLAHA
ʻO DonPipe 322 kahi ʻano o ka hui ʻana o nā polyols me ka hcfc-141b ma ke ʻano he mea hoʻoulu, e lawe ana i ka polyol ma ke ʻano he kumu nui, e hui pū me kahi mea kōkua kūikawā.ʻO kēia mea kūpono no nā pūpū hoʻoheheʻe wela o waho i hoʻohana ʻia no ka wai, ka aila a me ke kinoea pipelines . ʻO ka huahana polyurethane i hoʻomākaukau ʻia ma ka hana ʻana me ka isocyanate nā mea maikaʻi aʻe:
-- ka ikaika compressive maikaʻi a me ke kūpaʻa dimensional
-- kiʻekiʻe kokoke-cell rate a me ka maikaʻi wai hana
-- maikaʻi ka hana hoʻokaʻawale
