Peb Shanghai Theorem Chemicals tau cog lus rau cov khoom siv tshuaj tshiab, Polyurethane raw khoom thiab tshwj xeeb isocyanates, Tau ntau xyoo, nyob rau hauv lub tswv yim ntawm "Quality Oriented, Technology Guided", lub tuam txhab tau tsim raws liIsocyanate RE,RFE,1.5-Naphthalene Diisocyanate (NDI),PPDI (1,4-Phenylene Diisocvanate), thiab lwm yam...
Peb yog cov neeg muag khoom sab saum toj ntawm NDI (1,5-naphthalene diisocyanate) hauv Suav teb, nrog siab purity 99% min thiab cov nqi sib tw, peb NDI yog ib hom polyurethane (PU) ua los ntawm diisocyanate. Piv nrog MDI thiab TDI, NDI nrog cov ntsiab lus melting ntau dua, siab molecular rigidity, tsis tu ncua, thiab symmetry, uas tuaj yeem txhim kho qib ntawm theem sib cais ntawm polyurethane, ua rau NDI-raws li polyurethane tau txais cov khoom zoo heev thiab lub cev. NDI-raws li polyurethane muaj siab hnav tsis kam, siab kub tsis kam, corrosion kuj thiab zoo heev dynamic zog, thiab yog tsuas yog siv nyob rau hauv siab dynamic load thiab kub kuj zaus.
NDI (1,5-Naphthalene Diisocyanate) yog cov khoom siv raw ntawm polyurethane siab heev, uas tuaj yeem siv los tsim polyurethane elastomer nrog siab elasticity thiab siab hardness. NDI polyurethane elastomer muaj kev ua tau zoo heev. Nws muaj qhov sib piv tsis tau nrog lwm cov polyurethane elastomer, xws li kev ua haujlwm zoo heev, kev ua haujlwm siab heev, kev txiav zoo heev, hnav tsis kam thiab kub tsis kam. Yog li ntawd, NDI polyurethane elastomers yog dav siv nyob rau hauv lub tsheb poob siab absorbers, forklift bearing log, luam ntawv thiab dyeing textile roj hmab rollers, roj hmab scrapers, choj siv tsis thaiv blocks, tub rog kev lag luam, thiab lwm yam.
