Monga momwe zasonyezedwera, ma silicone surfactants monga MXS-6 yathu (yofanana ndi DC193) ndi ofunikira kwambiri pakukonza kapangidwe ka polyurethane kovuta komwe kumabweretsa ubwino wokhazikika komanso magwiridwe antchito abwino kwambiri mu nsapato.

MXS-6 imadziwika ngati chinthu chofunikira kwambiri kwa opanga omwe akufuna kupanga nsapato zapamwamba za PU kuti zigwiritsidwe ntchito m'njira zosiyanasiyana, kuyambira nsapato wamba komanso zamasewera mpaka nsapato zotetezeka komanso nsapato zolimba. Kutha kwake kupititsa patsogolo kayendetsedwe ka maselo, kukonza kayendedwe ka zinthu, ndikuwonetsetsa kuti pamwamba pake pali mtundu wabwino kwambiri womwe umakwaniritsa zomwe ogula akuyembekezera masiku ano.

Ku MINGXU NEW MATERIALS, tadzipereka kukhala patsogolo pa mayankho a polyurethane mumakampani opanga nsapato. Kudzipereka kwathu ku khalidwe labwino, limodzi ndi ukatswiri wathu waukadaulo komanso kuthekera kwa mayankho apadera, kumatiyika ngati mnzathu woyenera kwa opanga omwe akufuna kupanga zatsopano komanso kuchita bwino. Pogwiritsa ntchito ukadaulo wapamwamba monga MXS-6, mutha kuwonetsetsa kuti zidendene zanu za polyurethane zimapereka chitonthozo, kulimba, komanso magwiridwe antchito omwe amasiyanitsa nsapato zanu.

Tikukupemphani kuti mulumikizane nafe kuti mufufuze momwe ma polyurethane catalysts ndi ma surfactants athu angakuthandizireni kupita patsogolo molimba mtima, kukulitsa njira zanu zopangira nsapato ndikutumiza zinthu zabwino kwambiri pamsika.
