Ntawm ntau yam polyurethane systems,TDI -raws li polyether low-free prepolymer (CPU)tseem yog ib qho kev daws teeb meem dav dav rau cov tuam txhab nrhiav kev sib npaug ntawm cov nqi kev ua haujlwm, kev ua haujlwm yooj yim, thiab kev ua haujlwm ruaj khov.
Piv nrog cov pa TDI prepolymers,qis-dawb TDI polyurethane prepolymertxo qis TDI cov ntsiab lus pub dawb, txhim kho tus neeg teb xov tooj kev nyab xeeb thiab txo cov ntxhiab tsw thaum tsim khoom. Qhov no ua rau nws tshwj xeeb tshaj yog haum rauqhib casting polyurethane systems, phau ntawv nchuav txheej txheem, thiab me me - mus rau - nruab nrab PU elastomer manufacturers.
TDI-raws li polyether CPU muaj elasticity zoo, zoo rebound resilience, thiab ruaj khov hardness tswj. Tiav lawm polyurethane elastomers qhia txhim khu kev qha tensile zog thiab abrasion tsis kam, ua qhov system no zoo tagnrho rauPU log, kev lag luam chais, kev co dampers, thiab dav -lub hom phiaj polyurethane qhov chaw.
Los ntawm kev pom kev ua haujlwm,polyether-raws li qis- dawb prepolymersmuab cov tshuaj hydrolysis zoo dua thiab txhim kho kev ua siab ntev rau cov dej noo, uas yuav pab txo qis qhov tsis xws luag thiab ua kom cov khoom zoo sib xws txawm tias tsawg dua - dua - qhov chaw ua haujlwm zoo tshaj plaws.
Rau cov neeg tsim khoom polyurethane tab tom nrhiav kev paub tab, kev lag luam, thiab yooj yim -rau - txheej txheem kev daws teeb meem,TDI -raws li polyether low-free prepolymer (CPU)tseem yog ib qho kev ua tau zoo thiab kev sib tw xaiv.
