Lub rooj zaum ua npuas ncauj feem ntau yog hais txog polyurethane ua npuas ncauj, uas yog ua los ntawm ob cov khoom siv ntxiv rau cov khoom siv ntxiv thiab lwm yam khoom me me, uas yog foamed los ntawm pwm.Tag nrho cov txheej txheem tsim khoom tau muab faib ua peb txheej txheem: theem kev npaj, theem tsim khoom thiab theem tom qab ua tiav.
1. Kev npaj theem - kev tshuaj xyuas + kev sib xyaw
①Incoming khoom soj ntsuam:
Feem ntau xyuas seb cov dej cov ntsiab lus thiab viscosity ntawm polyether ua tau raws li qhov yuav tsum tau ua.Cov khoom no tshwj xeeb tshaj yog nyob rau lub caij ntuj no nyob rau sab qaum teb.
Kev sim ua npuas dawb pub dawb kuj tseem ua rau cov ntaub ntawv tuaj, feem ntau hnyav los xyuas seb lawv puas ua tau raws li qhov yuav tsum tau ua.
②Kev sib xyaw:
Kev sib xyaw yog ua raws li cov qauv tsim, thiab cov khoom siv sib xyaw tsis siv neeg tam sim no siv.FAW-Volkswagen lub rooj zaum ua npuas ncauj tau muab faib ua ob hom: cov khoom sib xyaw thiab cov khoom sib xyaw ua tus kheej.
Cov khoom sib xyaw ua ke:) A + B ob qhov kev daws teeb meem sib xyaw yog sib xyaw ncaj qha
Self-batching: sib tov POLY, uas yog, yooj yim polyether + POP + additives, thiab ces sib tov POLY thiab ISO
2. Ntau lawm theem - voj ntau lawm
Feem ntau, lub voj voog ntau lawm tau txais, feem ntau yog los ntawm ntau yam txheej txheem xws li nchuav, sib sau, demoulding, thiab pwm tu, raws li hauv qab no:
Ntawm lawv, pouring yog tus yuam sij, uas yog tsuas yog ua tiav los ntawm pouring manipulator.Cov txheej txheem sib txawv yog siv raws li txoj haujlwm sib txawv ntawm lub rooj zaum ua npuas ncauj, uas yog, foams nyob rau hauv cov cheeb tsam sib txawv yog nchuav, thiab cov txheej txheem tsis sib txawv (siab, kub, mis, foaming ntom, pouring route, teb index).
3. Tom qab ua tiav - suav nrog drilling, trimming, coding, kho, txau silencer ciab, laus thiab lwm yam txheej txheem
①Qhov - Lub hom phiaj ntawm kev qhib yog los tiv thaiv cov khoom deformation thiab nce elasticity.Muab faib ua lub tshuab nqus tsev adsorption thiab cov menyuam hom.
Tom qab cov npuas dej tawm ntawm pwm, nws yog ib qho tsim nyog yuav tsum qhib lub hlwb kom sai li sai tau.Lub sijhawm luv luv, qhov zoo dua, thiab lub sijhawm ntev tshaj plaws yuav tsum tsis pub tshaj 50s.
②Ntug trimming-ua npuas ncauj Vim yog cov txheej txheem ntawm cov pwm tso tawm, qee cov npuas npuas yuav ua rau ntawm ntug ntawm cov npuas dej, uas yuav cuam tshuam rau cov tsos thaum npog lub rooj zaum thiab yuav tsum tau muab tshem tawm ntawm tes.
③Coding - siv los taug qab hnub tsim khoom thiab batch ntawm npuas.
④Kev Kho - Ua npuas ncauj yuav tsim qhov tsis zoo me ntsis thaum lub sijhawm tsim khoom lossis demoulding txheej txheem.Feem ntau, kua nplaum yog siv los kho qhov tsis xws luag.Txawm li cas los xij, FAW-Volkswagen tau hais tias qhov chaw A tsis raug tso cai kho, thiab muaj cov qauv zoo tshwj xeeb los txwv kev kho cov haujlwm..
⑤Spray sound-absorbing wax - txoj haujlwm yog los tiv thaiv kev sib txhuam ntawm cov npuas dej thiab lub rooj zaum ncej kom tsim suab nrov
⑥Kev laus - Tom qab ua npuas dej yog molded los ntawm cov pwm, cov khoom siv foaming feem ntau tsis muaj kev cuam tshuam tag nrho, thiab yuav tsum muaj micro-reactions.Feem ntau, cov npuas dej raug tshem tawm hauv huab cua nrog catenary rau 6-12 teev rau kev kho.
qhib
Txiav
tom qab ripening
Nws yog precisely vim hais tias ntawm xws li ib tug complex txheej txheem uas Volkswagen lub rooj zaum ua npuas ncauj muaj zoo heev kev nplij siab thiab ib puag ncig tiv thaiv nrog tsawg tsw thiab tsis muaj emission.
