umkhiqizo

Desmodur RE / Isocyanate RE yezinamathelisi i-CAS 2422-91-5

Incazelo emfushane:

I-RE yethu ingumxhumanisi wokuxhumanisa osebenza kakhulu, osetshenziswa kuma-adhesives enziwe yi-hydroxyl polyurethane, iraba yemvelo noma yokwenziwa, inamandla amakhulu okuhlanganisa irabha neklabhu ukuze isetshenziswe ku-resin, antioxidant, ejenti leplastikhi, elizwela ingcindezi njll. ingasetshenziswa njenge-crosslinker esikhundleni se-BAYER's Desmodur RE.

Izici zomkhiqizo nezici

I-RE yethu ingumxhumanisi wokuxhumanisa osebenza kakhulu, osetshenziswa kuma-adhesives enziwe yi-hydroxyl polyurethane, iraba yemvelo noma yokwenziwa, inamandla amakhulu okuhlanganisa irabha neklabhu ukuze isetshenziswe ku-resin, antioxidant, ejenti leplastikhi, elizwela ingcindezi njll. ingasetshenziswa njenge-crosslinker esikhundleni se-BAYER's Desmodur RE.

Isicelo

Izinto zokunamathisela ezibili kumele zisetshenziswe esikhathini esisebenzayo ngemuva kokufaka i-RE. Ubude besikhathi esisebenzayo abuhlobene kuphela nokuqukethwe kwe-polymer, kodwa futhi nezinye izinto ezifanele (njenge-resin, i-antioxygen, i-plasticizer, i-solvent, njll. Uma ususondele esikhathini esisebenzayo, imvamisa amahora ambalwa noma usuku olulodwa lokusebenza, ingcina kuba nzima ukusebenza, futhi i-viscosity ikhuphuka maduzane. Ekugcineni, iba i-jelly engalungiseki. I-100 quality adhesive, Hydroxyl polyurethane (Polyurethane account for 20%), RE dose 4-7. Chloroprene rubber (Rubber account for 20%) , I-RE yethu yenza u-4-7.

Ezinye Izincazelo Ezihlobene

Isitoreji:

Sicela ugcinwe embizeni yokuqala evaliwe ngaphansi kuka-23 ℃, imikhiqizo ingagcinwa izinzile izinyanga eziyi-12. Izwela kakhulu kuningi; kuzoba ukukhiqiza i-carbon dioxide ne-urea engancibiliki ekuphenduleni ngamanzi. Uma ukuvezwa emoyeni womoya noma ukukhanya, kuzosheshisa ushintsho lombala, kepha umsebenzi osebenzayo ngeke uthinteke.
