Igiciro cyiza Desmodur RE / Isocyanate RE kubifata CAS 2422-91-5
RE yacu ni igikoresho gikora cyane gihuza, Ikoreshwa mumashanyarazi yakozwe na hydroxyl polyurethane, reberi karemano cyangwa sintetike, ifite imbaraga zihuza cyane muri reberi na cab ikoreshwa muri resin, antioxydeant, plasitike, ibyiyumvo byumuvuduko nibindi. Irashobora gukoreshwa nka crosslinker aho kuba BAYER's Desmodur RE.
Ibisobanuro birambuye:
Izina ryimiti: Triphenylmethane-4,4 ', 4' '- triisocyanate
Inzira ya molekulari: C22H13N3O3
CAS: 2422-91-5
MW: 367.36
Imiterere: uwabikoze
Imiterere yimiterere: HC [NCO] 3
Ubucucike: 1.0g / c m3, 20 ℃
Ingingo yo gushonga: 89 ℃
RE yacu, nanone yitwa TTI, ni igisubizo kirimo 27.5% triphenylmethane-4,4ˊ, 4 〞-triisocyanate na 72.5% ya Ethyl acetate. Nibintu byose bikiza / crosslinker yo gufatira kuri hydroxyl polyurethane, reberi karemano na sintetike, cyane cyane muguhuza ibikoresho bya reberi. Irakoreshwa cyane muguhuza ibyuma na reberi. Byongeye kandi, RE irashobora gukoreshwa kuri resin, antioxydeant, plasitike, nibindi. Mu murima wifatanije, RE ikoreshwa nkibikoresho byambukiranya imiti ya neoprene hamwe na / cyangwa p hydroxyl polyurethane ifata inkweto. Mubisanzwe, kugirango ukize ibifatika byibice 100 kuburemere (pbw) ukurikije urugero rusabwa rwa 4-7 pbw RE. Ubuzima bwinkono buvanze ni hafi yamasaha.
Ibice bibiri bigize ibice bigomba gukoreshwa mugihe gikurikizwa nyuma yo gushyira RE. Uburebure bwigihe cyakoreshwa ntabwo bujyanye gusa na polymer yibirimo, ariko nibindi bikoresho bifatika (nka resin, antioxyde, plastisike, solvent, nibindi. Iyo hafi yigihe gikurikizwa, mubisanzwe amasaha make cyangwa umunsi umwe wakazi, gufatira biba bigoye gukora, kandi viscosity irazamuka vuba. Ihinduka jelly idasubirwaho, Hydroxyl polyurethane (konti ya Polyurethane igera kuri 20%), RE dose ya 4-7. , RE yacu ikora 4-7.
Gupakira:
750g / icupa, amacupa 20 muri karito imwe, amakarito 24 cyangwa 30 muri pallet imwe;
20kg / ingoma, ingoma 18 cyangwa ingoma 27 muri pallet imwe;
55kg / ingoma, ingoma 8 cyangwa 12 muri pallet imwe;
180kg / ingoma, ingoma 4 muri pallet imwe
Ububiko:
Nyamuneka ubike mubibindi byumwimerere bifunze munsi ya 23 ℃, ibicuruzwa birashobora kubikwa neza mumezi 12. Birumva cyane kuri benshi; bizabyara karuboni ya dioxyde na urea idashonga muri reaction hamwe namazi. Niba guhura na teh umwuka cyangwa urumuri, bizihutisha amabara, ariko imikorere ifatika ntabwo izagira ingaruka.
