    Kufotokozera

    MOFAN ML90 ndi methylal yoyera kwambiri yokhala ndi kuchuluka kopitilira 99.5%, Ndi chinthu chopukutira chachilengedwe komanso chotsika mtengo chomwe chimagwira ntchito bwino paukadaulo. Chosakanizidwa ndi ma polyol, chimatha kuyaka mosavuta. Chingagwiritsidwe ntchito ngati chinthu chokhacho chopukutira mu kapangidwe kake, komanso chimabweretsa zabwino pamodzi ndi zinthu zina zonse zopukutira.

    Chiyero ndi Magwiridwe Osayerekezeka

    MOFAN ML90 imadziwika bwino pamsika chifukwa cha kuyera kwake kosayerekezeka. Methyal yoyera kwambiri iyi si chinthu chokhacho; ndi yankho lopangidwira opanga omwe amaika patsogolo ubwino ndi kukhazikika. Kuyera kwapamwamba kwa MOFAN ML90 kumatsimikizira kuti ikukwaniritsa zofunikira zolimba za mitundu yosiyanasiyana ya thovu, kupereka zotsatira zokhazikika ndikuwonjezera mtundu wonse wa chinthu chomaliza.

    Wothandizira Kuwononga Zachilengedwe ndi Zachuma

    Pamene mafakitale akuyesetsa kuchepetsa kuwononga chilengedwe, MOFAN ML90 ikuwoneka ngati chisankho chachilengedwe komanso chachuma. Kupanga kwake kumalola kuwongolera bwino kuyaka ikasakanizidwa ndi ma polyol, zomwe zimapangitsa kuti ikhale njira yotetezeka pa ntchito zosiyanasiyana. Kusinthasintha kumeneku kumatanthauza kuti MOFAN ML90 ingagwiritsidwe ntchito ngati chothandizira chokhacho chopukutira mu kapangidwe kake kapena kuphatikiza ndi zinthu zina zopukutira, zomwe zimapatsa opanga kusinthasintha komwe amafunikira kuti akonze bwino ntchito zawo.

    Ubwino

    ● Sizimayaka kwambiri kuposa n-Pentane ndi Isopentane zomwe zimayaka kwambiri. Mitundu yosiyanasiyana ya ma polyol okhala ndi Methylal yothandiza pa thovu la polyurethane imasonyeza kuwala kwamphamvu.

    ● Ili ndi mbiri yabwino ya poizoni wa chilengedwe.

    ● GWP ndi 3/5 yokha ya GWP ya Pentanes.

    ● Sizidzasungunuka m'madzi pakatha chaka chimodzi pamlingo wa pH woposa 4 wa ma polyol osakanikirana.

    ● Ikhoza kusakanikirana bwino ndi ma polyol onse, kuphatikizapo ma polyol a polyester onunkhira.

    ● Ndi chochepetsa kukhuthala kwamphamvu. Kuchepetsa kumadalira kukhuthala kwa polyol yokha: kukwerakukhuthala kwa thupi, kumachepetsa kwambiri.

    ● Mphamvu yotulutsa thovu ya 1 wt yowonjezera ndi yofanana ndi 1.7~1.9wt HCFC-141B.

    FAQ

    Ndimapanga thovu la polyurethane lopangidwa ndi khungu lofunikira kwambiri pazida zamagalimoto (mawilo oyendetsera galimoto, malo opumulira manja). Kodi MOFAN ML90 ingagwiritsidwe ntchito ngati chopumulira chokhacho?

    Inde, ML90 (high-methylal) ingagwiritsidwe ntchito ngati chinthu chokhacho chopukutira, chomwe chimapereka mawonekedwe abwino pamwamba ndi kapangidwe ka maselo kofanana komanso kotsika kwambiri.

    Fomu yanga yolimba ya thovu imagwiritsa ntchito HCFC-141b yomwe ikuchotsedwa. Kodi ML90 ingayilowe m'malo?

    Inde, ML90 ndi njira ina yosungira zachilengedwe komanso yotsika mtengo. Kutentha kwake (~42°C) ndi mphamvu yake yopumira ndizofanana, zomwe zimafuna kusintha kochepa kwa kapangidwe kake.

    Kodi mlingo wamba wa ML90 mu thovu losinthasintha la mipando ndi wotani?

    2–8 phr kutengera kuchuluka kwa chinthu chomwe mukufuna; kuchuluka kwa zinthu kumachepetsa kuchuluka kwa chinthucho koma kungapangitse thovu kufewa. Sakanizani ndi madzi kuti maselo atseguke bwino.

    Kodi ML90 ingasakanizidwe ndi zinthu zina zopukutira (monga madzi, cyclopentane, HFC 245fa)?

    Inde, imagwira ntchito mogwirizana ndi zinthu zonse zodziwika bwino zopukutira, zomwe zimapangitsa kuti kusungunuka kwa ma polyol kukhale bwino komanso kuchepetsa kuchuluka kwa zinthu zopukutira zomwe zimafunikira.

    Thovu langa lolimba pang'ono lopangira zinthu silikhala lolimba kwambiri ndi madzi okha. Kodi ML90 ingathandize bwanji?

    Kuwonjezera 3–5 phr ML90 kumachepetsa kuchuluka kwa madzi komwe kumafunika, kuchepetsa exotherm yamkati ndikuwonjezera kukhazikika kwa miyeso.

    Kodi MOFAN ML90 imatha kuyaka? Kodi mungaigwiritse ntchito bwanji mosamala mufakitale ya thovu?

    Inde, methylal imatha kuyaka. Gwiritsani ntchito zipangizo zoyenera zopumira mpweya, zothira pansi, komanso zoteteza kuphulika; zitha kusakanikirana bwino ndi ma polyol kuti muchepetse kuyaka.

    Thovu langa lolimba lopopera lili ndi malo owuma chifukwa cha kuuma kwa mpweya mwachangu kwa chinthu chopukusira. Kodi ML90 idzalikonza?

    Kuwira kwake pang'ono komanso kusungunuka bwino kwa polyols kumachepetsa kukula kwake, zomwe zimapangitsa kuti pamwamba pake pakhale posalala.

    Kodi ubwino wa ML90 ndi wotani kuposa acetone kapena zinthu zina zopukutira zomwe zili mu thovu losinthasintha?

    ML90 ili ndi fungo lochepa, imasungunuka bwino, ndipo imapereka maselo osalala; komanso siimayambitsa kusintha kwa mtundu wa thovu.

    Kodi ML90 ingagwiritsidwe ntchito mu polyurethane elastomers kuti muchepetse kuchulukana?

    Inde, pa ma elastomer a microcellular (monga nsapato), gwiritsani ntchito 1-3 phr ML90 pamodzi ndi madzi; zimathandiza kuchepetsa kuchulukana popanda maselo akuluakulu.

    Kodi kuyera kwa MOFAN ML90 n'chiyani ndipo kumakhudza bwanji ubwino wa thovu?

    Kuyera kwa ≥99.5% kumatsimikizira kuti thovu lomalizidwa limagwira ntchito bwino nthawi zonse, zotsatira zochepa, komanso fungo lochepa lotsalira.
