Daim ntawv thov
Polyester polyol siv rau kev ua npuas ncauj nruj tuaj yeem siv rau ntau daim ntawv thov:
Kev tsim kho kev lag luam: raws li thermal rwb thaiv tsev thiab cov khoom txuag hluav taws xob, siv rau phab ntsa, ru tsev, pem teb, thiab lwm yam.
Cov khoom siv tub yees: siv rau thermal rwb thaiv tsev ntawm cov tsheb tub yees, txias cia, tub yees, thiab lwm yam.
Tsheb thauj mus los: siv rau thermal rwb thaiv tsev thiab suab rwb thaiv tsev ntaub ntawv rau tsheb, aircraft, thiab lwm yam.
Cov khoom siv muaj: siv rau thermal rwb thaiv tsev ntawm cov kav dej thiab cov tso tsheb hlau luam kom txo tau lub zog poob.
Furniture manufacturing: siv los ua cov khoom siv hauv tsev rau cov khoom siv rooj tog.
Txoj kev tsim kho
Kev sib xyaw: Sib tov polyester polyol nrog lwm cov khoom xws li isocyanate, catalyst, foam stabilizer, thiab lwm yam.
Pouring: Muab cov khoom sib xyaw ua ke rau hauv pwm lossis qhov chaw tsim kho.
Foaming: Cov tshuaj tiv thaiv cov ntaub ntawv ua npuas ncauj sai sai nyob rau hauv qhov kev txiav txim ntawm cov catalyst los tsim cov qauv ua npuas ncauj.
Curing: Cov npuas dej solidifies nyob rau hauv ib lub sij hawm ntawm lub sij hawm los tsim cov khoom uas yuav tsum tau rigid ua npuas ncauj.
Demolding: Rau molded ua npuas ncauj, nws raug tshem tawm ntawm pwm tom qab kho.
Trimming: Txiav cov npoo ntawm cov npuas kom ua tiav qhov loj thiab cov duab.
Post-processing: Ua cov txheej txheem tom qab ua tiav xws li kev txiav thiab sib txuas raws li xav tau.
Thaum siv cov polyester polyol rau nruj ua npuas ncauj yuav tsum tau them sai sai rau:
Xyuas kom muaj qhov cua zoo thaum lub sij hawm tsim kho kom tsis txhob muaj cov vapors txaus ntshai.
Siv cov cuab yeej tiv thaiv tus kheej tsim nyog xws li khaub ncaws tiv thaiv tshuaj lom neeg, tsom iav thiab hnab looj tes.
Muab kev cob qhia kom raug rau cov neeg ua haujlwm tsim kho kom muaj kev nyab xeeb thiab zoo.
nruj me ntsis tswj qhov kev faib ua feem thiab sib tov uniformity ntawm cov tshuaj tiv thaiv cov ntaub ntawv los xyuas kom meej cov kev ua tau zoo ntawm cov npuas.
