Polyurethane foaming tshuab muaj cov cai nruj ntawm kev tuav thiab tswj cov txheej txheem ntau lawm. Lub tshuab tsis ua haujlwm, cov khoom siv raw, pwm, preheating kub thiab curing lub sij hawm ntawm cov khoom xaiv ncaj qha cuam tshuam rau molding ntawm cov khoom. Feem ntau elaborated cov ntsiab lus tswj ntawm cov txheej txheem foaming. Thaum yuav khoom, koj yuav tsum xaiv lub tuam txhab khoom foaming, uas yog tus yuam sij rau kev tsim cov khoom tsim nyog polymers. Cia cov chaw tsim khoom ntawm Kotai polyurethane foaming tshuab coj koj ib co saib thiab yuav tsum tau ntawm polyurethane foaming tshuab.
Lub tshuab high-pressure polyurethane foaming tshuab nruj me ntsis tswj qhov piv ntawm cov thawj cov kua rau cov kua txhaj tshuaj thiab qhov piv ntawm cov khoom siv dub, polyether thiab cyclopentane. Yog tias tag nrho cov tshuaj txhaj tshuaj tseem tsis hloov pauv, qhov feem pua ntawm cov khoom siv dub loj dhau, qhov feem pua ntawm cov khoom siv dawb yog loj heev, qhov feem pua ntawm cov khoom siv dawb yog siab dhau, thiab qhov kev faib ua feem ntawm cyclopentane hauv polyurethane high-pressure foaming tshuab yog heev. siab. Inhomogeneous proportions ntawm cov ntaub ntawv dawb yuav ua rau tsis sib xws, ua rau ua npuas ncauj shrinkage.
Yog tias lub tshuab ua npuas dej polyurethane ua haujlwm tsis raug, qee qhov chaw yuav ua tsis tiav, thiab kev kuaj xyuas yooj yim thiab kev saib xyuas yuav tsum tau ua raws li qhov chaw ua txhaum.
Yog hais tias ib feem ntawm lub tshuab ua npuas ncauj polyurethane ua tsis tiav, qhov ntsuas ntsuas yuav xa tawm cov lus, thiab cov zaub yuav nyem tam sim ntawd los qhia qhov chaw ntawm qhov txhaum. Qhov kev pab cuam yuav cia li xa tawm cov kev tiv thaiv raws li qhov chaw ua txhaum, xws li nres, ib feem nres, txhaj tshuaj nres, thiab lwm yam, thiab xa tawm lub tswb.
Tom qab kev daws teeb meem ntawm cov khoom siv tshuab polyurethane foaming, peb tuaj yeem nias lub pob rau kev daws teeb meem, thiab cov ntawv tsis ua haujlwm tau tshwm sim ua ntej yuav ploj mus. Yog tias qhov txhaum tsis raug daws, cov ntawv nyeem yuav tshwm sim tas li.
Tau kawg, thaum muaj teeb meem nrog lub tshuab ua npuas ncauj polyurethane, yuav tsum ceev faj tsis txhob nias lub khawm yooj yim, tab sis txhawm rau kho cov khoom siv polyurethane, thiab tom qab ntawd siv nws tom qab ua tib zoo tshuaj xyuas.
