ʻO Donpipe 301 ka waihona wai hoʻohui i nā polyols no ka pale ʻana i ka paipu
IOLELO HOOLAHA
ʻO kēia huahana kahi ʻano polyols hui pū me ka wai ma ke ʻano he mea hoʻohua, kahi i noiʻi kūikawā ʻia no ka PUF paʻa e hana i nā paipu insulation thermal.Hoʻohana nui ʻia ia i nā paipu mahu, liquefied nature gas holo paipu, aila paipu a me nā māla ʻē aʻe.ʻO nā hiʻohiʻona penei:
(1) kahe maikaʻi, ma ka hoʻoponopono ʻana i ke ʻano e kūpono i nā anawaena paipu like ʻole.
(2) kiʻekiʻe wela-kū'ē hana, lōʻihi kū i loko o 150 ℃
(3) maikaʻi haʻahaʻa wela dimensional paʻa
