Yisiphi i-Polyurethane Catalyst Eletha Imiphumela Engcono Ngo-2026 DMDEE Noma Ezinye Izindlela

Ngo-2026, i-DMDEE, kufaka phakathi i-MOFAN DMDEE ene-chemical identifier6425-39-4, kulindeleke ukuthi ihlale iyisikhuthazi esiphezulu sokukhiqizwa kwe-polyurethane. Ukukhetha isikhuthazi esifanele kubumba ikhwalithi nokuphepha komkhiqizo.

Indima Yokusungula Izinto Ezibalulekile Ku-Polyurethane

Kungani Ukukhetha Kwe-Catalyst Kubalulekile

Ai-catalyst iyisithako esiyinhlokoekukhiqizweni kwe-polyurethane. Isheshisa ukusabela kwamakhemikhali phakathi kwezingxenye eziyinhloko, isiza abakhiqizi ukulawula ukuthi izinto zakha ngokushesha kangakanani. Ukukhetha i-catalyst kungashintsha izinga lokusabela, isikhathi esithathayo ukuze igwebu liqine, kanye nekhwalithi yokugcina yomkhiqizo.

Ukukhethwa kwama-catalyst kuthinta kakhulu amazinga okusabela kanye nezakhiwo zemikhiqizo ye-polyurethane. Isibonelo, ama-catalyst endabuko afana nama-tertiary amines kanye nama-organometallic compounds angabonisa isivinini sokusabela esingaguquki. Lokhu kungaholela ezikhathini ezinde zokuqina kanye nezakhiwo ezibuthakathaka zemishini. Amanye ama-catalyst asebenza kahle kuphela emazingeni okushisa athile, okungabangela izinkinga uma izimo zenqubo zishintsha. I-catalyst efanele isiza ukulinganisela isikhathi sejeli kanye nesikhathi sokuqina, okuthinta ukuthi umkhiqizo wokugcina unamathela kahle kangakanani nokuthi uhlala isikhathi esingakanani.

Umthelela Ezimpahleni Ze-Foam

I-catalyst ayithinti nje kuphela indlela i-polyurethane eyakheka ngayo ngokushesha kodwa futhi namandla ayo nokuqina kwayo. Izifundo zibonisa ukuthi izinga elifanele le-catalyst, ngokuvamile eliphakathi kuka-0.5% no-3% wengxube iyonke, linikeza imiphumela emihle kakhulu. I-catalyst eningi kakhulu ingenza i-foam ibe buthaka futhi inciphise ikhono layo lokufaka umswakama. Ukuncane kakhulu kungashiya i-foam ibuthakathaka futhi ingazinzile.

• Ithonya lokukhetha i-Catalyst:
