Polyurethane (PU) yog cov khoom siv ntau yam uas tau siv dav hauv ntau lub lag luam vim nws cov khoom zoo xws li rwb thaiv tsev, soundproofing, poob siab absorbing, thiab thermal stability.
GRPU yog cov khoom siv sib xyaw ua haujlwm siab uas yog tsim los ntawm kev txhaj tshuaj iav fiber ntau rau hauv polyurethane resin los ntawm cov txheej txheem impregnation thiab extrusion.
Nws muaj cov compressive siab, tensile, thiab flexural lub zog, thiab paub txog nws qhov tshwj xeeb zoo xws li suab rwb thaiv tsev, thermal rwb thaiv tsev, hluav taws kub tsis kam, tiv thaiv kev laus, tsis tshua muaj linear expansion coefficient, thiab txuag hluav taws xob.
GRPU muaj qhov zoo ntawm lwm cov ntaub ntawv xws li aluminium alloy thiab yas steel nyob rau hauv cov nqe lus ntawm rwb thaiv tsev, cua siab tsis kam, huab cua nruj, dej nruj, suab rwb thaiv tsev, hluav taws kub tsis kam, thiab corrosion kuj. yuav raug rau ntau txheej txheej kho nrog nplua nuj los.
Cov iav fiber ntau yog ib qho inorganic fiber ntau nrog cov nplaim hluav taws zoo thiab tiv thaiv tshav kub, thiab nws cov ntsiab lus melting feem ntau yog siab dua 1000 degrees. Cov khoom siv polyurethane yog cov khoom siv thermosetting. Thaum raug hluav taws kub, lawv yuav tsim ib txheej carbonized rau ntawm qhov chaw los tiv thaiv cov nplaim taws los ntawm kev nkag mus tob thiab yuav tsis yaj lossis tsim cov tee dej.
Cov iav fiber ntau reinforced polyurethane cov ntaub ntawv sib xyaw yog qhov nyuaj rau hlawv thaum raug hluav taws, thiab qhov kub ntawm qhov hluav taws kub yog qhov nyuaj rau kev coj mus rau sab nraud. Raws li ntau yam hluav taws kub-resistant iav configuration, hluav taws-resistant kev ncaj ncees tuaj yeem ua tiav rau 0.5-1.5 teev
Qhov zoo:
1. lub teeb yuag thiab siab zog;
2. txuag hluav taws xob thermal rwb thaiv tsev thiab rwb thaiv tsev kub;
3. Kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob tseem ceeb;
4. corrosion kuj thiab aging kuj;
5.zoo seem stability;
6.it muaj huab cua tsis zoo;
7.Qhov kev ua haujlwm rwb thaiv tsev yog qhov zoo.
