Kukula kwa Zinthu Zothandiza Polurethane Zopanda Fungo Lochepa Msika Wapadziko Lonse

Chiyambi

Mzaka zaposachedwa,zoyambitsa polyurethane zopanda fungo loipa Zakhala chitukuko chachikulu mumakampani opanga polyurethane. Chifukwa cha miyezo yokhwima kwambiri padziko lonse lapansi yokhudza chilengedwe komanso kufunikira kwa makasitomala ambiri okhala ndi malo oyera m'nyumba, chitukuko chazotulutsira polyurethane zopanda mpweya woipa komanso fungo lochepa ikuyenda mofulumira. Opanga thovu losinthasintha komanso lolimba, zokutira, zomatira, ndi zotsekera pakadali pano akuika patsogolo zinthu zosakaniza zomwe zimaphatikiza magwiridwe antchito apamwamba, VOC yotsikasndikusamalira chilengedwe popanda kusokoneza reactivity.

Chifukwa Chake Fungo Ndi Lofunika Pakupanga Polyurethane

Ma catalyst achikhalidwe a amine, ngakhale kuti amagwira ntchito bwino kwambiri polimbikitsa polyurethane reaction pakati pa isocyanates ndi polyols, nthawi zambiri amatulutsa ma volatile amines panthawi yopanga kapena pambuyo pa kuchira. Utsi uwu ukhoza kubweretsa:

Sfungo lamphamvu la amines mu zinthu zomalizidwa (monga thovu ndi zokutira)

M'nyumbamavuto a mpweya wabwino

Wogwira ntchitomavuto okhudzana ndi kukhudzidwa ndi malamulo komanso kutsata malamulo

Pofuna kukwaniritsa zosowa zaumoyo ndi zachilengedwe zomwe zilipo panopa, mafakitale akusamukira mwachangu kumakina othandizira ochepetsa fungo loipa komanso osasinthasintha kwambiriMa catalyst awa amachepetsa mpweya woipa pamene akusunga thovu labwino komanso kugwira ntchito bwino.

Kukwera kwa Ma Catalyst Opanda Fungo Lochepa

Ma catalyst a polyurethane osanunkha bwino apangidwa kutikuchepetsa kusasinthasintha ndikuwongolera kusankhaMwa kusintha kapangidwe ka mamolekyu awo kapena kuyambitsa magulu ogwira ntchito osinthika, ma catalyst awa amatha kugwirizana ndi polyurethane matrix, motero amaletsa kusinthasintha kwa mankhwala opanga fungo.

Ukadaulo wotsogola m'munda uno ndi uwu:

Zothandizira za amine zogwira ntchitozomwe zimagwirizana bwino ndi polima

Zothandizira za amine zotsekedwandi kumasulidwa kolamulidwa panthawi yochitapo kanthu

Machitidwe a amine otsika kwambirindi kukhazikika kwa hydrolytic

Mwachitsanzo, zinthu zoyambitsa matenda monga Mingxu New Materials'MXC-R40 ndiMXC-37 zapangidwa makamaka kuti ziwonetseFungo lochepa, kuchita bwino kwambiri, komanso kukhala ndi mphamvu zokwanira zopanga thovuAmagwiritsidwa ntchito kwambiri muthovu lolimba lopopera, zipangizo zotetezera kutentha kwa zipangizo zamagetsi, thovu lamkati la magalimotondi Makina a HFO.

Zoyendetsa Zachilengedwe ndi Malamulo

Zinthu zingapo padziko lonse lapansi zikufulumizitsa kukhazikitsidwa kwazoyambitsa polyurethane zopanda fungo loipa:

Mochulukirachulukiramalamulo okhwima a VOC (volatile organic compound) ndi utsi wotulutsa mpweya ku Ulaya, North America, ndi Asia.

Zikalata zokhazikika (LEED, BREEAM, GREEGUARD) akulimbikitsa kugwiritsa ntchito zipangizo zoyera.

Kufunika kwa ogula Mipando ya mipando yotulutsa mpweya wochepa, matiresi, ndi mkati mwa magalimoto ikukula.

Kusintha kwa mafakitale kupita ku HFO ndi machitidwe opangira thovu lopangidwa ndi madzi, zomwe zimafuna zinthu zina zosinthira zinthu.

Opanga omwe akugwiritsa ntchitoukadaulo wothandiza kutulutsa mpweya wochepa Sikuti zimangokwaniritsa zofunikira pa malamulo okha komanso zimawonjezera phindu la mtundu wa malonda ndikupeza mwayi wopikisana nawo m'misika yotumiza kunja.

Ubwino Wogwiritsa Ntchito Zothandizira Polurethane Zopanda Fungo Lochepa

Kukhazikitsazoyambitsa fungo lochepaKupanga polyurethane kumapereka zabwino zambiri:

Kuchepetsa fungo mu zinthu zomalizidwa za thovu

Chitetezo chabwino cha ogwira ntchito komanso malo osungira zomera

Mpweya wabwino wamkati kwa ogwiritsa ntchito

Kutsatira miyezo ya VOC emission

Kuchita bwino kokhazikika komanso ma profiles okhazikika a thovu

Ubwino uwu umapangitsazoyambitsa polyurethane zopanda fungo loipa chisankho chosankhidwa kwambiri ndi opanga thovu padziko lonse lapansi.

Kugwiritsa Ntchito Mu Machitidwe a Polyurethane

Ma catalyst osanunkha kwambiri tsopano akugwiritsidwa ntchito pafupifupi m'makina onse a polyurethane:

Ma thovu osinthasinthamipando yamagalimoto, ma cushion a mipando, matiresi

Thovu lolimba: mapanelo oteteza kutentha, ma thovu opopera, ma thovu oziziritsira

Zophimba, zomatira, zotsekera, ndi ma elastomer (MLANDU): imafuna kuti mpweya woipa usatuluke kapena utuluke pang'ono

Makamaka,Kuteteza thovu lopopera lopopera ndi HFOmakina amapindula ndi zinthu zochepetsera fungo zomwe zimapangitsa kuti ntchito ikhale yochuluka pamene akuletsa fungo losafunikira la amine m'malo omangidwa mobisa.

Mapeto

Chizolowezi chopita kuzoyambitsa polyurethane zopanda fungo loipa sikuti imangosonyeza kuyankha malamulo okha komanso kusintha kwa makampani kuti apititse patsogolo kukhazikika, chitetezo, komanso ubwino. ukadaulo wothandiza kutulutsa mpweya wochepa, opanga polyurethane amatha kupanga zinthu zoyera, zopangira thovu zogwira ntchito bwino, komanso kukhutitsa ogwiritsa ntchito kwambiri.

Monga m'modzi mwa ogulitsa otsogola ku China opanga ma catalyst a polyurethane,Zipangizo Zatsopano za Mingxu amapitiliza kupanga zatsopanozoyambitsa fungo lochepa, zogwira ntchito kwambiri kuti tikwaniritse zosowa za makina amakono a thovu. Zambiri za malonda athu zikuphatikizapoMXC-R40, MXC-37, ndi MXC-DPA, kupereka mayankho abwino kwambiri kwa makasitomala omwe akufuna kukhala ndi mgwirizano pakati pa kuchitapo kanthu, kukhazikika, ndi udindo pa chilengedwe.
