1,5-naphthalene diisocyanate (NDI) yog ib hom polyurethane (PU) synthesized 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.
Lub castable elastomer ua los ntawm NDI muaj cov yam ntxwv zoo heev thiab hnav tsis kam, thiab nrog me me damping, siab resilience, thiab tsis tshua muaj cua sov. Nws tuaj yeem siv rau hauv siab dynamic load thiab kub resistant zaus. Moulded khoom ua los ntawm NDI muaj lub zog tsim kua muag, tsis muaj kev puas tsuaj, tsis tshua muaj compression teeb thiab zoo heev resilience. NDI-based microporous polyurethane elastomer cov khoom lag luam muaj cov cua sov endogenous tsawg, me me deformation mus tas li thiab zoo rigidity nyob rau hauv dynamic load. Cov khoom siv tshwj xeeb microporous polyurethane no tsuas yog siv rau lub tsheb poob siab absorbing thiab cushioning Cheebtsam.
Peb yog cov neeg tseem ceeb hauv kev lag luam NDI. Peb lub peev xwm tsim NDI yog 500 MT txhua xyoo thiab txuas ntxiv mus.
