    He methylal maʻemaʻe kiʻekiʻe ʻo MOFAN ML90 me ka ʻike ma mua o 99.5%，He mea puhi ecological a hoʻokele waiwai hoʻi me ka hana loea maikaʻi. Hoʻohui ʻia me nā polyols, hiki ke hoʻomalu ʻia kona lapalapa. Hiki ke hoʻohana ʻia ma ke ʻano he mea puhi wale nō i loko o ka hoʻohuihui ʻana, akā lawe mai ia i nā pono i ka hui pū ʻana me nā mea puhi ʻē aʻe a pau.

    ʻO ka Maʻemaʻe a me ka Hana Kūlike ʻole

    Kū i waho ʻo MOFAN ML90 ma ka mākeke ma muli o kona maʻemaʻe ʻole. ʻAʻole wale kēia methylal maʻemaʻe kiʻekiʻe he huahana; he hopena ia i hoʻolālā ʻia no nā mea hana e hoʻokau mua i ka maikaʻi a me ke kūpaʻa. ʻO ka maʻemaʻe kiʻekiʻe o MOFAN ML90 e hōʻoiaʻiʻo ana e hoʻokō ia i nā koi koʻikoʻi o nā noi huʻa like ʻole, e hāʻawi ana i nā hopena kūlike a hoʻonui i ka maikaʻi holoʻokoʻa o ka huahana hope loa.

    Mea puhi ʻāina a me ka hoʻokele waiwai

    I ka hoʻoikaika ʻana o nā ʻoihana e hōʻemi i ko lākou kapuaʻi kaiapuni, kū mai ʻo MOFAN ML90 ma ke ʻano he koho ecological a me ka hoʻokele waiwai. ʻO kona ʻano hana e ʻae ai i ka kaohi pono ʻana i ka lapalapa ʻana i ka wā e hui pū ʻia me nā polyols, e lilo ia i koho palekana no nā ʻano hana like ʻole. ʻO kēia ʻano versatility ʻo ia hoʻi hiki ke hoʻohana ʻia ʻo MOFAN ML90 ma ke ʻano he mea puhi wale nō i nā ʻano hana a i ʻole i hui pū ʻia me nā mea puhi ʻē aʻe, e hāʻawi ana i nā mea hana i ka maʻalahi e pono ai lākou e hoʻomaikaʻi i kā lākou mau kaʻina hana.

    Nā Pōmaikaʻi

    ● ʻOi aku ka liʻiliʻi o ke ahi ma mua o ka n-Pentane a me Isopentane i hiki ke lapalapa loa. ʻO ka hui ʻana o nā polyols me ka nui pono o Methylal no nā hua polyurethane e hōʻike ana i kahi kiʻekiʻe o ka flash point.

    ● He ʻano maikaʻi kona no ka ecotoxicology.

    ● ʻO GWP he 3/5 wale nō ia o ka GWP o nā Pentanes.

    ● ʻAʻole ia e hydrolyze i loko o 1 makahiki ma ka pae pH ma luna o 4 o nā polyols i hui pū ʻia.

    ● Hiki ke hui pū ʻia me nā polyols āpau, me nā polyols polyester ʻala.

    ● He mea hoʻemi ikaika ia i ka mānoanoa. Aia ka hoʻemi ʻana i ka mānoanoa o ka polyol ponoʻī: ʻo ke kiʻekiʻeʻo ka mānoanoa, ʻoi aku ke kiʻekiʻe o ka hōʻemi.

    ● ʻO ka pono o ka huʻa ʻana o 1 wt i hoʻohui ʻia ua like ia me 1.7~1.9wt HCFC-141B.

    Nā nīnau i nīnau pinepine ʻia

    Hana wau i ka huʻa polyurethane ʻili hoʻohui no nā ʻāpana kaʻa (nā huila hoʻokele, nā lima hoʻomaha). Hiki ke hoʻohana ʻia ʻo MOFAN ML90 ma ke ʻano he mea puhi wale nō?

    ʻAe, hiki ke hoʻohana ʻia ʻo ML90 (high-methylal) ma ke ʻano he mea puhi wale nō, e hāʻawi ana i ka hoʻopau ʻili maikaʻi a me ke ʻano like o nā cell me ka haʻahaʻa haʻahaʻa.

    Hoʻohana kaʻu ʻano huʻa paʻa i ka HCFC-141b kahi e hoʻopau ʻia nei. Hiki iā ML90 ke pani iā ​​ia?

    ʻAe, he koho ʻē aʻe no ka nohona a me ka hoʻokele waiwai ʻo ML90. Ua like kona pae paila (~42°C) a me ka pono o ka puhi ʻana, e koi ana i ka hoʻoponopono liʻiliʻi o ka hoʻohuihui ʻana.

    He aha ka nui maʻamau o ML90 i ka huʻa palupalu no nā lako hale?

    2–8 phr ma muli o ka nui o ka pahuhopu; ʻo nā pae kiʻekiʻe e hōʻemi i ka nui akā hiki ke hoʻonui i ka palupalu o ka huʻa. E hoʻohui me ka wai no ka wehe ʻana o ke keena kūpono.

    Hiki ke hoʻohui ʻia ʻo ML90 me nā mea puhi ʻē aʻe (e laʻa, ka wai, cyclopentane, HFC 245fa)?

    ʻAe, hana pū ia me nā mea puhi maʻamau a pau, e hoʻomaikaʻi ana i ka solubility i loko o nā polyols a e hoʻemi ana i ka nui o ka mea puhi pū e pono ai.

    ʻAʻole paʻa ka paʻa o kaʻu huʻa semi-rigid no ka hoʻopili ʻana me ka wai wale nō. Pehea e kōkua ai ʻo ML90?

    ʻO ka hoʻohui ʻana i 3–5 phr ML90 e hōʻemi ana i ka pae wai e pono ai, e hoʻohaʻahaʻa ana i ka exotherm kūloko a hoʻomaikaʻi i ke kūpaʻa dimensional.

    He mea lapalapa paha ʻo MOFAN ML90? Pehea e lawelawe ai me ka palekana i loko o kahi mea kanu huʻa?

    ʻAe, he mea lapalapa ka methylal. E hoʻohana i ka ea kūpono, ka hoʻoheheʻe ʻana, a me nā lako pale pahū; hiki ke hoʻohui palekana ʻia me nā polyols e hōʻemi i ka lapalapa.

    He ʻili ʻinoʻino ko kaʻu huʻa paʻa pīpī ma muli o ka mahu wikiwiki ʻana o ka mea puhi. E hoʻomaikaʻi anei ʻo ML90 iā ia?

    ʻO kona kiko paila kūpono a me ka solubility maikaʻi i loko o nā polyols e hōʻemi ana i ka hoʻonui mua ʻana, e hāʻawi ana i kahi ʻili laumania.

    He aha ka pōmaikaʻi o ML90 ma luna o ka acetone a i ʻole nā ​​​​mea puhi kino ʻē aʻe i loko o ka huʻa palupalu?

    ʻOi aku ka haʻahaʻa o ke ʻala o ML90, ʻoi aku ka maikaʻi o ka solubility, a hāʻawi i nā cell ʻoi aku ka maikaʻi; ʻaʻole hoʻi ia e hoʻoulu i ka hoʻololi ʻana o ka huʻa.

    Hiki ke hoʻohana ʻia ʻo ML90 i nā elastomers polyurethane e hōʻemi i ka density?

    ʻAe, no nā elastomers microcellular (e like me, nā kapuaʻi kāmaʻa), e hoʻohana i ka 1-3 phr ML90 me ka wai; kōkua ia i ka hoʻemi ʻana i ka density me ka ʻole o nā cell nui.

    He aha ka maʻemaʻe o MOFAN ML90 a pehea e pili ai i ka maikaʻi o ka huʻa?

    ʻO ka maʻemaʻe ≥99.5% e hōʻoiaʻiʻo i ka hana mau, nā hopena ʻaoʻao liʻiliʻi, a me ke ʻala haʻahaʻa i koe i ka huʻa i hoʻopau ʻia.
