Txoj kev loj hlob ntawm polyurethane prepolymer
Mar 24, 2021
Txawm hais tias kev siv cov txheej txheem kub xovxwm sintering los npaj cov boron carbide ceramics tuaj yeem txo qhov kub thiab txias thiab ua kom qhov ceev ntawm lub cev sintered, qhov kub ntawm sintering tseem tseem siab. Txhawm rau txhawm rau txhim kho kev ua tau zoo ntawm cov cam khwb cia polyurethane, txo qhov kub ntawm sintering thiab txo cov nqi tsim khoom, cov neeg yuav sib xyaw ua ke ntawm sintering thiab kub nias sintering tau ua tiav cov txiaj ntsig zoo kawg li.
Polyurethane prepolymer yog ib yam tshiab ntawm cov khoom siv. Nrog rau txoj kev loj hlob ntawm peb lub teb chaws thiab kev txhim kho tsis tu ncua ntawm kev sib tw ua lag luam, qhov kev thov rau cov khoom siv no kuj tau hloov pauv ntau, qee zaum txawm tias cov khoom tsis txaus. Nkag siab txog ntau yam ntawm cov khoom siv no Kev tsim khoom siv tshuab tuaj yeem ua kom zoo dua ntawm cov khoom siv no.
