Kev piav qhia tus cwj pwm

DB 75 yog cov kua kub thiab lub teeb stabilizer system tsim rau polyurethanes

Daim Ntawv Thov

DB 75 siv rau hauv polyurethanes xws li Reaction Injection Molding (RIM) polyurethane thiab thermoplastic polyurethane (TPU). Cov khoom sib xyaw kuj tseem siv tau rau hauv cov ntawv thov sealant thiab nplaum, hauv polyurethane txheej ntawm tarpaulin thiab pem teb nrog rau hauv tawv hluavtaws.

Cov yam ntxwv/cov txiaj ntsig

DB 75 tiv thaiv kev ua tiav, lub teeb thiab huab cua ua rau puas tsuaj
ntawm cov khoom polyurethane xws li khau hauv qab, cov twj paj nruag thiab cov vaj huam sib luag qhov rooj, lub kauj tsheb, qhov rai encapsulations, lub taub hau thiab caj npab so.
DB 75 tuaj yeem ntxiv tau yooj yim rau cov tshuab aromatic lossis aliphatic polyurethane rau cov thermoplastic moldings, semi-rigid integral foams, in-mold skinning, dope applications. Nws tuaj yeem siv nrog cov ntaub ntawv ntuj thiab cov xim. DB 75 yog qhov tsim nyog rau kev npaj cov xim sib zog rau cov kab ke saum toj no.
Cov txiaj ntsig ntxiv:
yooj yim rau twj, kua dej nchuav tau uas tso cai rau kev tswj hwm tsis muaj plua plav, kev ntsuas tshuaj tsis siv neeg thiab luv lub sijhawm sib tov
tag nrho cov kua pob; tsis muaj kev tso dej ntawm cov khoom ntxiv hauv theem polyol txawm tias nyob rau qhov kub qis
tsis kam rau exudation / crystallization hauv ntau lub PUR systems

Cov khoom tsim cov kua ntshiab, me ntsis daj

Cov lus qhia rau kev siv

Cov qib siv ntawm DB 75 ntau ntawm 0.2% thiab 1.5%, nyob ntawm seb lub substrate thiab kev ua tau zoo ntawm daim ntawv thov kawg:
Cov ua npuas dej ob yam khoom sib xyaw ua ke 0.6% - 1.5%
Cov nplaum 0.5% - 1.0%
Cov tshuaj nplaum 0.2% - 0.5%
Cov ntaub ntawv kev ua tau zoo ntawm DB 75 muaj rau ntau daim ntawv thov.
