Txoj kev ua ntawmSaj zawg zog polyurethane ua npuas ncaujkoom nrog ntau kauj ruam:
Txoj Kev Tsim:Cov txheej txheem pib nrog kev tsim ntawm npuas dej, uas feem ntau cuam tshuam nrog tov ua ke polycors (polymeric resins), isocyanates, tshuab cov neeg sawv cev, surfactants, thiab additives. Qhov tseeb muaj pes tsawg leeg thiab cov sib piv ntawm cov feem no nyob ntawm cov khoom xav tau ntawm cov npaus.
Nws:Cov khoom xyaw xyaw ua ke nyob rau hauv cov tov khoom ceev lossis cov chav tsev sib xyaw. Qhov no ua kom pom tseeb kev sib xyaw thiab tawg ntawm cov khoom siv kom ua tiav cov qauv ua npuas ncauj npuas.
Nchuav lossis faib tawm:Cov qauv ua npuas ncauj sib xyaw yog tom qab ntawd nchuav lossis faib rau hauv cov pwm lossis nkag mus rau hauv txoj siv tawv conveyor, nyob ntawm seb cov khoom kawg xav tau, nyob ntawm cov khoom kawg xav tau. Qhov kev xaiv ntawm cov pwm lossis conveyor siv nyob ntawm qhov xwm txheej xws li ua npuas ncauj ntom, tuab, thiab cov duab.
Kev nthuav dav thiab kho tau:Ib zaug hliv rau hauv cov pwm lossis mus rau ntawm tus lej conveyor, cov ua npuas ncauj ua ke hauv qab cov tshuaj tiv thaiv uas muaj kev nthuav dav thiab kho tus kheej. Thaum lub sij hawm no, lub tshuab sawv cev ua npuas dej ua kom ua npuas ncauj kom nthuav dav thiab sau cov pwm lossis kis tau tusyees ntawm txoj siv tawv. Ib txhij, cov polyurethane undergoes undergoes crosslinking kev phiv tshuaj, tsim cov qauv ua npuas ncauj.
Ua npuas tsim:Kev ua npuas ncauj nthuav dav tau tso cai kho thiab txias, thaum lub sijhawm uas nws ua tau zoo rau cov qauv kev hloov pauv tau, kev ua qauv ntawm tes. Lub sijhawm kho tau tuaj yeem sib txawv nyob ntawm cov yam ntxwv xws li cov qauv tsim, huab cua sov, thiab cov av noo.
Kev Txhim Kho lossis Txiav:Thaum ua npuas ncauj tau kho tau txaus thiab txias, nws tau muab tshem tawm ntawm cov pwm lossis conveyor siv. Qee qhov xwm txheej, cov npaus yuav tuaj yeem ua cov txheej txheem ntxiv xws li txiav lossis txhuam kom ua tiav qhov kev xav tau ntev.
Kev Kho Mob Tom Qab:Tom qab kev ua txhaum lossis txiav, cov npaus yuav tuaj yeem tsim cov txheej txheem kev kho mob ntxiv xws li trimming, compression, lossis ua tiav saum toj kom tau raws li cov khoom lag luam tshwj xeeb.
Tswjhwm Zoo:Thoob plaws hauv kev tsim khoom, kev tswj hwm zoo yog siv los xyuas kom meej tias cov ua npuas ncauj tau raws li qhov kev xav tau, ruaj, qauv cell, thiab lwm yam khoom. Qhov no tuaj yeem ua yeeb yam kev tshuaj xyuas, kuaj lub cev, thiab kuaj tus qauv.
Ntim thiab faib:Thaum ua npuas ncauj tau dhau los tswj cov tshev zoo, nws tau muab faib rau cov khoom lag luam lossis cov rooj tog zaum txuas ntxiv, cov rooj tog zaum rooj tog, thiab lwm yam.
