Cov txheej txheem ua haujlwm ntawm PU daim txhuam cev ua npuas ncauj tshuab
PU daim txhuam cev ua npuas ncauj tshuab yog cov khoom siv tseem ceeb rau kev tsim daim txhuam cev. Qhov kawg zoo ntawm daim txhuam cev yog nyob ntawm lub tshuab kev ua tau zoo, tus neeg sawv cev foaming formulation, thiab tus neeg teb xov tooj kev txawj ntse. Yog li, yuav ua li cas raws nraim PU daim txhuam cev ua npuas ncauj ua tiav cov txheej txheem foaming?
I. Kev npaj ua ntej foaming
Ua ntej, precisely npaj cov foaming tus neeg sawv cev (feem ntau polyurethane foaming raw cov ntaub ntawv uas muaj expandable hlaws dai) raws li qhov yuav tsum tau sponge ceev, hardness, thiab lwm yam kev ua tau zoo. Muab cov ntaub ntawv npaj ua kua rau hauv cov khoom sib tov thiab nplawm ntawm lub tshuab foaming kom ntseeg tau tias sib xyaw ntawm txhua yam khoom.
II. Kub thiab siab hloov thaum lub sij hawm foaming txheej txheem
Cov khoom sib xyaw ua ke yog pub rau hauv thaj tsam tshuaj tiv thaiv ntawm lub tshuab ua daim txhuam cev thiab pib ua kom sov. Cov hlaws nyob rau hauv tus neeg sawv cev foaming tsis ua npuas hauv qab 80 degree; Lawv tsuas yog ua rau molecular diffusion. Thaum qhov kub siab tshaj 80 degree, cov hlaws dai maj mam nthuav dav thiab muag muag, tsim ntau kaw, tsis txuas hauv hlwb.
Raws li qhov kub thiab txias nce ntxiv, qis - boiling - cov ntsiab lus ntawm cov khoom (lossis cov dej noo) nyob rau hauv cov ntaub ntawv raw vaporize los tsim cov pa. Cov chav no nkag mus rau cov hlwb uas twb tsim lawm, tsis tu ncua ua rau lub siab sab hauv. Nyob rau hauv kev sib xyaw ua ke ntawm qhov kub thiab txias ntawm lub sijhawm, cov phab ntsa ntawm tes tau maj mam ncab thiab thinned. Thaum lub siab sab hauv ntawm cov hlwb ua siab txaus los rhuav tshem cov phab ntsa ntawm tes, cov hlwb tawg los yog txuas, thaum kawg tsim ib qho qhib -cell los yog ib nrab - qhib- cell porous qauv - cov ntaub so ntswg uas peb paub.
III. Curing thiab txiav tom qab foaming
Tom qab foaming tiav lawm, daim txhuam cev thaiv yog txuas ntxiv tawm ntawm qhov hluav taws xob ntawm lub tshuab ua npuas ncauj txuas ntxiv rau kev ua daim txhuam cev thiab nkag mus rau hauv qhov chaw kho. Nws raug tso rau ntawm chav tsev kub lossis cua sov rau ob peb mus rau kaum ob teev kom tso cai rau cov tshuaj tiv thaiv sab hauv kom tiav kom huv si thiab cov qauv ntawm tes kom ruaj khov. Thaum kawg, daim txhuam cev loj yog txiav rau hauv cov khoom sib txawv thiab cov duab ntawm PU txiav tshuab raws li cov neeg siv khoom xav tau.
IV. Hom thiab xaiv cov tshuab foaming
Tam sim no, muaj ob lub ntsiab ntawm cov tshuab ua npuas ncauj hauv khw: phau ntawv thiab tsis siv neeg.
Cov lag luam yuav tsum xaiv qhov tsim nyog raws li lawv cov khoom muag thiab cov phiaj xwm kev loj hlob.
Nws yuav tsum tau muab sau tseg tias qhov precision ntawm foaming tus neeg sawv cev formulation ncaj qha cuam tshuam cov txheej txheem foaming. Yog hais tias qhov kev faib ua feem ntawm foaming tus neeg sawv cev tsis sib npaug, txawm tias lub tshuab ua npuas ncauj siab tshaj plaws yuav tawm tsam los tsim cov khoom zoo - daim txhuam cev. Tsis tas li ntawd, cov ntsiab lus xws li ambient kub, raw khoom kub, nplawm ceev, thiab tu txheej txheem ntawm lub tshuab foaming tuaj yeem hloov kho cov qauv ntawm tes. Niaj hnub no, cov neeg siv khoom muaj kev xav tau ntau ntxiv rau daim txhuam cev tes, kev ua haujlwm zoo, kev phooj ywg ib puag ncig, thiab lwm yam, thiab cov khoom lag luam qis tau nrawm tawm ntawm kev ua lag luam. Yog li ntawd, cov tuam txhab lag luam yuav tsum tuaj koom rau txhua qhov kev nthuav dav kom ntseeg tau tias kev ruaj ntseg ntawm cov txheej txheem foaming.
Cov txheej txheem ua haujlwm ntawm cov tshuab ua npuas dej yog qhov tseem ceeb ntawm kev sib koom ua ke ntawm lub cev nthuav dav thiab tshuaj lom neeg cov tshuaj tiv thaiv. Los ntawm kev tswj hwm qhov kub thiab txias, siab, thiab lub sijhawm, cov ntaub ntawv ua kua tau hloov mus rau hauv cov khoom siv nrog cov qauv ntawm tes. Txawm hais tias phau ntawv los yog tsis siv neeg ua npuas ncauj ua tshuab, cov ntsiab lus tseem ceeb tseem zoo ib yam. Tsuas yog los ntawm kev nkag siab tob txog lub foaming mechanism thiab precisely kho cov ntaub ntawv raw thiab cov khoom tsis muaj peev xwm ua lag luam tsis tu ncua tsim cov khoom ua npuas ncauj uas ua tau raws li kev lag luam zoo.
