Kufotokozera kwa Meta: Dziwani magawo osiyanasiyana ogwiritsira ntchito ma catalyst a polyurethane, kuyambira thovu losinthasintha mpaka kutchinjiriza kwamphamvu kwambiri. Dziwani momwe mayankho athu atsopano a catalyst amathandizira khalidwe, magwiridwe antchito, komanso kutsatira malamulo a chilengedwe pakupanga kwa PU.
Chiyambi
Polyurethane (PU) ndi polima yogwiritsidwa ntchito m'mafakitale ambiri, ndipo ma catalyst a polyurethane amachita gawo lofunikira kwambiri pakulamulira kupanga kwake. Monga opanga otsogola opanga ma catalyst a PU ogwira ntchito bwino, timapereka mayankho apadera opangidwa kuti akonze bwino momwe thovu limagwirira ntchito, limathandizira, komanso limalumikizirana m'makina a polyurethane. M'nkhaniyi, tikuyang'ana magawo akuluakulu ogwiritsira ntchitozinthu zoyambitsa polyurethane, kusonyeza momwe amathandizira kupanga zinthu zatsopano ndi magwiridwe antchito m'magawo osiyanasiyana.
1. Thovu Losinthasintha la Polyurethane
Mapulogalamu:Mipando, matiresi, mipando yamagalimoto, nsapato zonyamulira.
Udindo Wothandizira:Mu machitidwe osinthasintha a thovu, ma catalyst amathandiza kulinganiza momwe gelling (polyol-isocyanate) ndi flushing (water-isocyanate) zimachitikira kuti apange maselo ofanana, kufewa, komanso kulimba mtima.MXC-37 (DMAEE)ndi MXC-A1 (BDMAEE) zimapereka mpweya wochepa komanso mphamvu yowongolera bwino zochita, zomwe zimapangitsa kuti zikhale zoyenera kwambiri m'mafakitale a magalimoto ndi mipando komwe kutsatira malamulo a VOC ndikofunikira.
2. Thovu Lolimba la Polyurethane
Mapulogalamu:Mafiriji, mafiriji, mapanelo, mabolodi otetezera kutentha, zotetezera mapaipi.
Udindo Wothandizira:Ma thovu olimba amafuna liwiro la kuchitapo kanthu mwachangu komanso kukhazikika kwa miyeso. Ma catalyst monga MXC-15 (Potassium Octanoate) ndi MXC-T12 (Dibutyltin Dilaurate) amatsimikizira kuti zinthu zimasintha kwambiri komanso kuti makina azikhala olimba. Izi ndizofunikira kwambiri pakupanga zinthu zozizira, kutchinjiriza zomangamanga, komanso kupanga zida zamagetsi.
3. Spray Polyurethane Thovu (SPF)
Mapulogalamu:Kuteteza nyumba, makina ophimba denga, kudzaza mabowo.
Udindo Wothandizira:Makina a SPF amafunika kuwongolera bwino nthawi yopangira kirimu, nthawi yokwera, komanso nthawi yopanda kugwedezeka. Ma catalyst athu monga MXC-R40 ndi MXC-MB20 ndi abwino kwambiri kuti agwiritsidwe ntchito ndi makina okhala ndi HFO, omwe amapereka fungo lochepa komanso kuuma mwachangu komanso kumamatira bwino. Zinthuzi zimagwiritsidwa ntchito kwambiri popanga nyumba zokhazikika kuti zisunge mphamvu komanso kuteteza chilengedwe.
4. Mapanelo a thovu a Polyisocyanurate (PIR)
Mapulogalamu:Ma panelo a masangweji a makoma, denga, ndi zipinda zosungiramo zinthu zozizira.
Udindo Wothandizira:Makina a thovu a PIR amafunikira ma catalyst omwe amalimbikitsa kuyeretsa bwino moto komanso kugwira ntchito bwino kwa kutentha. MXC-TMA yathu idapangidwa makamaka kuti ithandizire kapangidwe ka maselo ofanana komanso kuchiritsa kwamphamvu kumbuyo, koyenera kupanga mizere yopitilira komanso yosapitirira.
5. Thovu ndi Elastomer za Microcellular
Mapulogalamu:Zovala zapakati pa nsapato, mawilo owongolera, mapanelo a zida, zoziziritsira kugwedezeka.
Udindo Wothandizira:Magwiritsidwe ntchito amenewa amafuna zinthu zoyambitsa zomwe zimapangitsa kuti nkhungu zisamagwire bwino ntchito komanso kuonetsetsa kuti zinthuzo zimakhala zolimba. Mayankho monga MXC-R70 ndi MXC-B20 amapereka mgwirizano wabwino pakati pa kuyenda koyambirira ndi kuchira komaliza, zomwe zimapangitsa kuti zinthuzo zikhale bwino komanso kuti zinthuzo zigwire bwino ntchito.
6. Zomatira ndi Zotsekera za Zigawo Ziwiri
Mapulogalamu:Kumanga, kulumikiza magalimoto, kuyika mphika wamagetsi.
Udindo Wothandizira:Zothandizira monga MXC-T12 ndi MXC-BDMA zimathandiza kuti pakhale mphamvu yolumikizana bwino komanso kuti pakhale mgwirizano wolimba, zomwe ndizofunikira kwambiri kuti pakhale mgwirizano wolimba. Zogulitsa zathu zimathandiza kuti mpweya wochepa wa VOC ukhale wogwirizana ndi mitundu yosiyanasiyana ya polyol ndi isocyanate.
Chifukwa Chiyani Sankhani Ife?
Timapereka:
Ma catalyst formulations opangidwa mwamakonda omwe akugwirizana ndi zosowa zanu zapadera
Thandizo lonse laukadaulo kuyambira labu mpaka kukula kwa kupanga
Mayankho ochepetsa mpweya woipa komanso oteteza chilengedwe
Zinthu zodalirika padziko lonse lapansi komanso kupezeka kosalekeza
Kaya mukupanga thovu lolimba kwambiri, chotenthetsera chosagwiritsa ntchito mphamvu zambiri, kapena ma elastomer olimba, pulogalamu yathu ya catalyst imapereka magwiridwe antchito otsimikizika komanso magwiridwe antchito abwino.
Lumikizanani nafe
Kodi mwakonzeka kukulitsa mapangidwe anu a polyurethane? Lumikizanani ndi gulu lathu kuti mudziwe zambiri za mndandanda wathu wa MXC catalyst ndikupempha zitsanzo kapena ma datasheet aukadaulo.
