Kugwiritsa ntchito MXC-A1 catalyst popanga thovu lofewa

Mingxu Chemicals ndi kampani yogulitsa zinthu zopangira polyurethane, ndipo tsopano tikukupatsani njira zosiyanasiyana zogwiritsira ntchito thovu lofewa la polyurethane komanso ntchito yathu.MXC-A1Chothandizira pakupanga kwawo. Ma thovu ofewa a polyurethane amagwiritsidwa ntchito kwambiri chifukwa cha kusinthasintha kwawo komanso kusinthasintha kwawo, kuthandizira mafakitale monga mipando, magalimoto, masewera, zamankhwala ndi ma phukusi. Ndi zinthu zabwino monga kuphimba, kutchinjiriza mawu ndi kusefa, ma thovu ofewa ndi omwe amasankhidwa kwambiri pa ntchito zapamwamba.

Ma thovu ofewa a polyurethane amapangidwa ndi mankhwala omwe amapangidwa pakati pa ma diisocyanates ndi ma polyol, omwe onse amachokera ku mafuta osakonzedwa. Kuphatikiza apo, ma polyol amatha kupezeka kuchokera ku mafuta achilengedwe obwezerezedwanso, zomwe zimapangitsa kuti pakhale njira zokhazikika zopangira. Akaphatikizidwa, ma diisocyanate ndi ma polyol amachitapo kanthu kuti apange thovu lokhala ndi kapangidwe ka uchi. Kapangidwe kameneka kamakhala ndi mphamvu zopindika, kusinthasintha komanso mphamvu zabwino zoperekera, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pa mipando, zofunda, mipando yamagalimoto, zida zamasewera, zida zamankhwala, kulongedza, nsapato ndi makapeti. Kapangidwe ka thovu lofewa la polyurethane kamathandizanso kuti mawu aziteteza komanso kusefa, zomwe zimapangitsa kuti likhale lothandiza kwambiri m'magawo ambiri.

Chinsinsi cha kukhala ndi thovu lokhazikika komanso kapangidwe kake ndi kugwiritsa ntchito ma catalyst ndi zowonjezera zinazake. Catalyst yathu ya MXC-A1, yotchedwaBDMAEE(Nambala ya CAS: 3033-62-3) kapena N,N,N',N' -tetramethyl-2,2′ -oxybis (ethylamine), ndi chothandizira kwambiri cha tertiary amine, chomwe chimagwiritsidwa ntchito kwambiri popanga zinthu zofewa za thovu, makamaka popanga zinthu za RIM zomwe zimakhala ndi rebound yambiri. Thovu la polyurethane limapangidwa ndi momwe diisocyanate ndi polyol zimagwirira ntchito. Madzi opanda mtundu mpaka achikasu pang'ono awa amalimbikitsa momwe urea (water-isocyanate) imagwirira ntchito mu thovu lofewa komanso lolimba la polyurethane, zomwe zimapangitsa kuti pakhale ntchito yothandiza komanso kusankha bwino panthawi yotulutsa thovu.

Kapangidwe kake ka MXC-A1 kamapangitsa kuti ikhale yoyenera kupanga mitundu yonse ya thovu losinthasintha, makamaka zinthu zopindika kwambiri komanso ntchito za Reaction Injection Molding (RIM). Mwa kusintha kukula kwa thovu panthawi yochitapo kanthu pakati pa ma polyol ndi ma isocyanates, ma amine catalysts ndi ma surfactants amalola kusintha kuchuluka kwa thovu ndi kulimba kwake. Zowonjezera zina monga zoletsa moto ndi ma bacteriostatic agents zimawonjezeranso kuchuluka kwa thovu, makamaka m'magawo a ndege, magalimoto, akunja, ndi am'madzi.

Ndi chothandizira chathu cha MXC-A1, opanga thovu osinthasintha amatha kupanga bwino, kusinthasintha kwa thovu komanso kugwiritsa ntchito mitundu yosiyanasiyana. Kuti mudziwe zambiri za MXC-A1 ndi ma catalyst ena, chonde titumizireni uthenga kuti mudziwe momwe ma catalyst athu angakwaniritsire zosowa zanu zopangira thovu losinthasintha la polyurethane.
