Udindo wofunikira wa ma catalyst a polyurethane pakupanga ma sandwich panel ndi njira zatsopano zothetsera mavuto

Ukadaulo wamakono wa masangweji ndi zipangizo zapakati pa polyurethane

Monga chinthu chatsopano chofunikira kwambiri mumakampani omanga, ma polyurethane sandwich panels akhala chinthu chofunikira kwambiri pa mafakitale, malo osungiramo zinthu ozizira, malo ogwirira ntchito oyera ndi nyumba zina. Zinthu zopangidwa ndi ma polyurethane foam pakati zimadalira kwambiri makina a polyurethane catalyst chifukwa cha ntchito yake yabwino kwambiri. Ma MXC series catalysts athu ndi abwino kwambiri popanga ma sandwich panels, zomwe zingathandize kwambiri kuti zinthu ziyende bwino komanso kuti zinthu ziyende bwino.

Dongosolo la Catalyst la mapanelo a masangweji

Ubwino wapadera waMXC-37 (DMAEE)chothandizira

MXC-37 (2-(2-(dimethylamino)ethoxy)ethanol, CAS 1704-62-7) ndi chinthu chothandizira kusintha kwa amine chomwe chimabweretsa njira zambiri zopangira ma sandwich panel:
- Makhalidwe opanda mpweya woipa komanso opanda fungo lochepa: kuthetsa vuto la fungo la ma catalyst achikhalidwe a amine ndikukonza malo opangira zinthu
- Kutulutsa thovu kwambiri: makamaka koyenera popanga thovu lokhala ndi madzi ambiri kuti thovu lizikula mokwanira
- Njira yogwiritsira ntchito kawiri: ingagwiritsidwe ntchito yokha ngati chothandizira chachikulu kapena kuphatikiza ndi BDMAEE
- Kugwirizana kwakukulu: koyenera machitidwe osiyanasiyana a polyester ndi polyether polyol
Mu mzere wopitilira wa mapangidwe a mapanelo a sandwich, MXC-37 ikhoza kupereka njira yokhazikika yochitira zinthu kuti zitsimikizire kufanana ndi kukhazikika kwa thovu, zomwe ndizofunikira kwambiri kuti mapanelo a sandwich akhale osalala komanso okhazikika.

Kupita patsogolo kwa ukadaulo waMXC-15(njira ya potaziyamu octanoate)

MXC-15 (CAS 3164-85-0), monga chothandizira cha isocyanurate chogwira ntchito bwino, imapereka chithandizo chofunikira pakupanga ma panel a sandwich a PIR:
- Kuchuluka kwa kusintha kwakukulu: kumalimbikitsa isocyanate trimerization ndikuwonjezera kukhazikika kwa kutentha kwa thovu
- Yogwiritsidwa ntchito pa njira yoyezera kukhuthala kwakukulu: imapangitsa kuti kayendedwe kake ka zinthu zolimba kakhale kofanana komanso kofanana
- Yotsika mtengo komanso yothandiza: kuchuluka kochepa kowonjezera kumatha kukhala ndi zotsatira zabwino kwambiri zoyambitsa
- Dongosolo lofananira la PIR laukadaulo: lopangidwira makamaka mapanelo a sandwich a polyisocyanurate
MXC-15 ikhoza kupititsa patsogolo kwambiri kukana moto komanso kukhazikika kwa ma sandwich panels, kuti athe kusungabe mawonekedwe abwino kwambiri a makina m'malo otentha kwambiri.

Udindo waukulu wazoyambitsakupanga masangweji

Pakupanga ma panel a sandwich a polyurethane, makina othandizira amakhudza mwachindunji zizindikiro zazikulu izi:
1. Kutuluka kwa thovu: onetsetsani kuti zipangizozo zadzaza bwino m'kati mwa mapanelo kuti zipewe kusowa kwa zinthu.
2. Liwiro lochiritsa: gwirizanani ndi liwiro lomwe mzere wopangira wopitilira umafunika kuti muwonjezere mphamvu zopangira
3. Kapangidwe ka selo: kamakhudza kutentha kwa thupi ndi mphamvu ya makina a gulu la masangweji
4. Kugwira ntchito kwa guluu: kumatsimikiza mphamvu yolumikizirana pakati pa zinthu zapakati ndi guluu
5. Kukhazikika kwa miyeso: kumalepheretsa kusintha kwa gulu komwe kumachitika chifukwa cha kuchepa kwa thovu
Gulu lathu laukadaulo likhoza kupereka njira yabwino kwambiri yothandizira mizere yosiyanasiyana yopangira ndi zofunikira za malonda mwa kuwongolera molondola chiŵerengero cha MXC-37 ndi MXC-15, kuthandiza makasitomala kukwaniritsa:
- Wonjezerani liwiro la mzere wopangira ndi 20-30%
- Wonjezerani kuchuluka kwa ziyeneretso za malonda kufika pa 98%
- Chepetsani kugwiritsa ntchito mphamvu ndi 15-20%
- Kusunga ndalama zambiri pachaka

Thandizo laukadaulo ndi ntchito zaukadaulo

Timapereka chithandizo chaukadaulo chathunthu kwa opanga ma sandwich panel:
- Ntchito yokonza ma formula: sinthani makina othandizira malinga ndi njira yomwe kasitomala alipo
- Chitsogozo cha magawo a njira: perekani kutentha kwabwino kwa zinthu, kutentha kwa nkhungu ndi malingaliro ena ofunikira a magawo
- Kuyambitsa ntchito yopangira: Ogwira ntchito zaukadaulo adzatsogolera kuyambitsa ntchito yopangira pamalopo
- Thandizo pakuwunika khalidwe: Kuthandiza kukhazikitsa njira yowongolera khalidwe labwino

Pezani zambiri za malonda ndi upangiri waukadaulo

Tikukupemphani opanga ma sandwich panel onse kuti adziwe zambiri za momwe ma catalyst a MXC amagwirira ntchito bwino. Ngati mukufuna zambiri zaukadaulo kapena pemphani zitsanzo zaulere, chonde titumizireni uthenga kudzera m'njira zotsatirazi:
