Chiyambi
Ma elastomer a polyurethane ndi gulu la ma polima osinthasintha komanso ogwira ntchito kwambiri omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana kuphatikizapo magalimoto, zomangamanga, nsapato, ndi mafakitale. Kuphatikiza kwawo kwapadera kwa kulimba, kusinthasintha, komanso kukana mankhwala kumapangitsa kuti akhale abwino kwambiri m'malo ovuta. Gawo lofunika kwambiri, lomwe nthawi zambiri limanyalanyazidwa popanga ma elastomer apamwamba a polyurethane ndi dongosolo la catalyst—makamaka ma amine catalyst, omwe amathandiza kuwongolera momwe zinthuzo zimagwirira ntchito komanso mawonekedwe omaliza a zinthuzo.
Ku MINGXU NEW MATERIALS, timapanga ma catalyst a polyurethane ogwira ntchito bwino kwambiri. Chimodzi mwa zinthu zathu zazikulu, MXC-37 (DMAEE), chimagwira ntchito yofunika kwambiri pakugwiritsa ntchito ma elastomer osiyanasiyana powonjezera mphamvu ya reaction pamene tikuonetsetsa kuti mpweya woipa ndi wochepa komanso fungo lochepa.
Zothandizira za Polyurethanemu Elastomer Systems
Mu mapangidwe a polyurethane elastomer, ma catalyst amawongolera kuchuluka kwa zochita ziwiri zazikulu:
1. Kuyankha kwa gelling (polyol ndi isocyanate)
2. Kuphulika kwa mpweya (madzi ndi isocyanate)
Mosiyana ndi thovu, ma elastomer nthawi zambiri amafunika kupukutidwa pang'ono kuti asunge mawonekedwe olimba. Komabe, pazinthu zina monga ma microcellular elastomer kapena reaction injection molding (RIM), kulinganiza bwino pakati pa thovu ndi gelling ndikofunikira kwambiri kuti pakhale kukhuthala, kulimba, komanso kutha kwa pamwamba.
MXC-37 (DMAEE): Chothandizira Kwambiri cha Amine cha Elastomers
MXC-37, yomwe imadziwikanso kuti 2-dimethylaminoethylethanol (DMAEE), ndi chothandizira cha amine chapamwamba chomwe chimapangidwa kuti chigwire bwino ntchito mu elastomer ndi microcellular systems. Ndi yothandiza kwambiri makamaka mu mankhwala okhala ndi madzi ambiri, komwe kulamulira thovu ndi kuwongolera fungo ndikofunikira kwambiri.
Ubwino Waukulu wa MXC-37 mu Elastomers:
Fungo Lochepa, Kapangidwe Kosatulutsa Utsi:Monga chothandizira chosatulutsa mpweya komanso chochepetsa fungo, MXC-37 imachepetsa fungo la amine lomwe limapezeka m'zigawo zomalizidwa za elastomer—makamaka zofunika kwambiri m'nyumba zamagalimoto ndi zinthu zogwiritsidwa ntchito ndi anthu.
Ntchito Yotulutsa Thovu Lambiri:Ngakhale mu machitidwe a elastomer omwe ali ndi thovu lochepa kapena lolamulidwa, MXC-37 imathandizira kapangidwe ka maselo kofanana komanso kuwongolera kuchulukana kwa maselo pamene zotsatira za microcellular zikufunika.
Kugwirizana Kwabwino Kwambiri:MXC-37 imagwirizana ndi mitundu yosiyanasiyana ya ma polyester ndi polyether, zomwe zimapangitsa kuti ikhale yoyenera ma elastomer ofewa komanso olimba, komanso thovu lofewa lokhazikika komanso lolimba la thovu lolimba.
Kugwiritsa Ntchito Mosiyanasiyana: Kumagwiritsidwa ntchito kwambiri mu:
Ma microcellular polyurethane elastomers (monga nsapato, zopumira pamanja)
Makina a RIM (mabampa a magalimoto, mapanelo)
Ma foam a elastomer osinthasintha komanso olimba kwambiri
Ma CD ndi ma elastomer oteteza ku dzuwa
N’chifukwa Chiyani Muyenera Kusankha MXC-37 pa Dongosolo Lanu la Elastomer?
Kupanga ma elastomer a polyurethane ogwira ntchito bwino kumafuna kulondola, kusasinthasintha, komanso kuwongolera. MXC-37 imapereka zonsezi pomwe ikuthandiza opanga mapangidwe kukwaniritsa miyezo yokhwima yazaumoyo ndi zachilengedwe. Kaya mukupanga zida zamagalimoto zopepuka kapena zida zolimba zamafakitale, MXC-37 imawonjezera njira ndi khalidwe la zinthu.
Mapeto
Pamene kufunikira kwa makina oyeretsera a polyurethane elastomer oyera komanso ogwira ntchito bwino kukupitirira kukula, kusankha chothandizira choyenera n'kofunika kwambiri kuposa kale lonse. MXC-37 (DMAEE) imapereka magwiridwe antchito, kutsata chilengedwe, komanso kusinthasintha kofunikira kuti ikwaniritse zofunikira zamakono zopangira.
Lumikizanani nafe lero kuti mudziwe momwe MXC-37 ingathandizire bwino kapangidwe kanu ka polyurethane elastomer.
