Amine Yogwira Ntchito Kwambiri Yothandiza pa Machitidwe Ochepetsa Mpweya Woipa
MXC-DPA ndi chothandizira chamadzimadzi chapamwamba kwambiri chomwe chimapangidwa kuti chithandizire kuchira m'magwiritsidwe osiyanasiyana a PU.
MXC-DPA ndi chothandizira chapamwamba cha amine chomwe chimagwira ntchito bwino chomwe chimapangidwa kuti chikwaniritse miyezo yokhwima kwambiri ya VOC mumakampani opanga polyurethane:
-
Kapangidwe ka Hydroxyl Kogwira Ntchito:Mosiyana ndi ma catalyst achikhalidwe, MXC-DPA ili ndi magulu a hydroxyl omwe amalumikizana ndi PU polymer matrix, zomwe zimapangitsa kuti pasakhale kusamuka komanso kuti fungo losatha likhale lochepa.
-
Kulondola kwa Maselo:Ndi kulemera kwa molekyulu ya$218.34$ndipo kapangidwe kake kamagwira ntchito ziwiri, kamapereka mawonekedwe okhazikika komanso oyenera omwe ndi ofunikira pa thovu lopangidwa bwino komanso losinthasintha.
Kugwira Ntchito Moyenera ndi Thovu
Kapangidwe ka mamolekyu a MXC-DPA (CAS 63469-23-8), chothandizira chabwino kwambiri cha amine chothandizira machitidwe a PU otsika mpweya.
Kwa mainjiniya opanga zinthu, mawonekedwe apadera a mankhwala a MXC-DPA amatanthauza kuwongolera bwino kwambiri ntchito yokonza zinthu komanso khalidwe la zinthu zomaliza:
-
Kupaka ndi Kupyoza Moyenera:Imapereka njira yosinthasintha yolumikizirana yomwe imalimbikitsa kupangika kwa thovu nthawi zonse komanso kukula kwa polima, kuteteza kugwa kwa thovu lamkati kapena kusinthasintha kwa kachulukidwe.
-
Yokonzedwa bwino kuti igwiritsidwe ntchito ndi RIM & Flexible Thovu:Kugwira ntchito kwapadera kwa MXC-DPA kumapangitsa kuti ikhale chisankho chabwino kwambiri cha Reaction Injection Molding (RIM) ndi mipando yapamwamba yamagalimoto komwe kulimba kwa kapangidwe kake ndikofunikira kwambiri.
-
Kapangidwe ka Maselo Komwe Kali Bwino:Mwa kuwongolera kayendedwe ka reaction, zimathandiza kupanga kapangidwe kofanana komanso kotseguka kwa maselo, kukulitsa mpweya wabwino komanso chitonthozo cha thovu la polyether losinthasintha.
Ubwino wa Chitetezo cha Njira ndi Unyolo Wopereka
Timapereka deta yowonekera bwino yaukadaulo kuti tithandize oyang'anira kugula zinthu kuchepetsa zoopsa ndikuwonjezera magwiridwe antchito opangira:
-
Chitetezo cha Malo Owala Kwambiri:Ndi kutentha kwa 90°C ndi kutentha kwa 212°C, MXC-DPA imapereka kukhazikika kwa kutentha kwambiri kuposa njira zina zosakhazikika, zomwe zimachepetsa chiopsezo cha moto mufakitale.
-
Kusamvetsetsana ndi Kusagwiritsa Ntchito Mosavuta:Madzi otsika kukhuthala amalumikizana bwino ndi ma polyol ambiri ndi zowonjezera, kuonetsetsa kuti mlingo wake ndi wolondola komanso kupewa kutsekeka kwa zida m'mizere yopangira yokha.
-
Madzi Ochepa Otsimikizika:Kuwongolera kwathu khalidwe labwino kumasunga madzi pansi pa 1%, kuteteza kusokonezeka kwa isocyanate reaction ndikuwonetsetsa kuti thovu limakhala lolimba nthawi zonse.
