Lub teeb yuag raws li tus qauv tseem ceeb ntawm txoj kev loj hlob yav tom ntej ntawm kev tsim tsheb hauv tsheb, nws yog ib qho tsim nyog yuav tsum ua kom zoo siv cov khoom siv polymer, kom lub teeb yuag ntawm lub tsheb tuaj yeem ua tiav, tab sis kuj muaj qee lub luag haujlwm ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, tab sis kuj. txhawm rau ua kom muaj kev nkag siab zoo ntawm lub tsheb zoo meej, kom qhov kev ua tau zoo ntawm lub tsheb tuaj yeem txhim kho, tuaj yeem ua rau hauv lub tsheb tsim qauv thiab kho kom zoo nkauj ntawm kev siv cov khoom siv polyurethane.

1 Polyurethane ua npuas ncauj

Polyurethane ua npuas ncauj yog tsim los ntawm isocyanate thiab hydroxyl compounds foamed nyob rau hauv polymerisation, polyurethane ua npuas ncauj yuav muab faib ua saj zawg zog thiab semi-rigid thiab rigid cov ntaub ntawv, saj zawg zog ua npuas ncauj yog tsuas yog siv nyob rau hauv lub tsheb tsim rautsheb headreststhiab lub ru tsev tsheb thiab lwm yam ntaub ntawv uas tib neeg tuaj yeem tiv tauj ncaj qha, vim tias nws cov yam ntxwv tuaj yeem rov ua dua, tuaj yeem tiv thaiv tib neeg kev nyab xeeb, tuaj yeem txhim kho lub tsheb kev nyab xeeb.Cov ntaub ntawv semi-rigid feem ntau yog siv rau cov qauv xws li dashboards, uas tuaj yeem txuag lub sijhawm hauv kev tsim khoom thiab ruaj khov dua.Rigid cov ntaub ntawv yog tsuas yog siv nyob rau hauv lub tsheb cabin rwb thaiv tsev.Polyurethane ua npuas ncauj feem ntau yog txhim kho los ntawm kev ntxiv cov nplaim hluav taws kom ncua kev sib tsoo, nres cov pa taws lossis txawm tias tua hluav taws kub hnyiab los ua kom cov nplaim hluav taws kub hnyiab ntawm cov npuas dej, yog li txhim kho kev nyab xeeb ntawm lub tsheb.Nws muaj cov nyhuv filling zoo, tiv thaiv corrosion thiab txo cov suab nrov hauv lub tsheb.

2 Cov tshuaj tiv thaiv txhaj tshuaj molded polyurethane khoom

Cov khoom siv polyurethane no yog tsim los ntawm cov pwm los ntawm cov ntaub ntawv raw khoom thiab yuav luag tsis muaj qhov txawv ntawm cov hlau hais txog kev nruj thiab lub zog, tab sis yog 50% sib zog dua hlau thiab tuaj yeem ua rau lub teeb yuag ntawm lub tsheb, feem ntau yog rau lub cev thiab lub kauj tsheb.Lub kauj log, raws li cov qauv tseem ceeb ntawm lub tsheb, tuaj yeem ua kom muaj kev nyab xeeb ntawm tsev neeg noj su, thaum muaj kev sib tsoo tuaj yeem txo qhov kev raug mob rau tus neeg tsav tsheb, tab sis kuj ua kom muaj kev ruaj ntseg ntawm cov qauv.Lub bumper ntawm ntau lub tsheb kuj yog ua los ntawm cov khoom zoo li no, thiab cov kev txhawb zog sab hauv kuj tseem tuaj yeem ua kom zoo dua kom ntseeg tau tias tus neeg tsav tsheb raug kev hem thawj tsawg.Lub ntsiab yog vim li cas rau kev siv ntawm polyurethane nyob rau hauv lub cev panels yog hais tias nws muaj ib tug zoo cuam tshuam quab yuam thiab xyuas kom meej tias tag nrho cov kev ua tau zoo ntawm lub cev tsis cuam tshuam los ntawm deformation nyob rau hauv ntau qhov chaw.

3 Polyurethane elastomers

Polyurethane elastomers yog siv hauv kev tsim tsheb ua cov qauv tseem ceeb xws lipoob siab absorbingcushioning blocks, raws li cov khoom siv elastic polyurethane muaj cov khoom zoo cushioning thiab yog siv ua ke nrog cov khoom siv lub caij nplooj ntoos hlav muaj zog ntawm lub chassis los txhim kho cov txiaj ntsig ntawm kev poob siab absorbing cushioning blocks thiab txhim kho kev nplij siab ntawm lub tsheb, zoo li cov ntaub ntawv hauv feem ntau tsheb.Lub airbags kuj yog ua los ntawm cov elastic polyurethane heev, raws li cov qauv no yog qhov kawg barrier los tiv thaiv tus neeg tsav tsheb thiab muaj lub luag haujlwm tseem ceeb hauv kev ua si, xav tau lub zog thiab elasticity ntawm airbag kom tau raws li qhov yuav tsum tau ua, thiab elastic polyurethane yog qhov haum tshaj plaws. xaiv, thiab cov khoom siv polyurethane kuj yog lub teeb, feem ntau airbags tsuas yog txog 200g.
Log tshebyog ib qho tseem ceeb ntawm kev tsav tsheb, cov khoom siv roj hmab zoo tib yam muaj lub neej ua haujlwm luv luv thiab tsis tuaj yeem siv nyob rau hauv cov xwm txheej muaj zog, thiab lawv kuj muaj kev cuam tshuam tsis zoo rau tib neeg kev noj qab haus huv, yog li cov ntaub ntawv zoo dua yuav tsum tau xaiv, thiab cov ntaub ntawv polyurethane tuaj yeem ua tau raws. Cov kev cai no, thiab tseem muaj peev txheej tsawg dua thiab cov yam ntxwv ntawm cov txheej txheem yooj yim dua, qhov kub tsis kam ntawm polyurethane log tsheb thaum muaj xwm ceev nres General, qhov no kuj yog nyob rau hauv kev siv tshwj xeeb ntawm ntau qhov laj thawj, dav dav polyurethane log tsheb yog txheej txheem, tuaj yeem ua rau lub log tsheb hloov. rau cov kev cai sib txawv, yog li ntawd lub log tsheb yuav tsis tsim muaj kuab paug, ntsuab heev, cia siab tias yav tom ntej yuav daws tau qhov teeb meem ntawm polyurethane log tsheb tsis resistant rau kub kub, zoo dua mus cuag kev siv dav.

4 Polyurethane nplaum nplaum

Lub hydrogen daim ntawv cog lus ntawm polyurethane thiab cov khoom yuav tsum tau sib koom ua ke yuav txhim khu lub molecular cohesion thiab ntxiv ua kom lub bonding ntau zog, lub polyurethane nplaum kuj muaj zoo toughness thiab adjustability, polyurethane nplaum muaj zoo heev shear zog thiab tej yam kuj, haum rau ntau yam. Cov txheej txheem nplaum ua haujlwm, muaj qhov ua tau zoo heev, cov nplaum polyurethane muaj kev ua tau zoo, tuaj yeem hloov mus rau qhov sib txawv thermal expansion coefficient ntawm kev sib txuas, muaj cov khoom siv polyurethane tuaj yeem siv los ua cov nplaum nplaum rau cov tsheb kom ua tiav cov nyhuv sealing zoo, tsheb iav thiab lub cev ruaj khov dua, ua kom lub zog tag nrho thiab lub zog ntawm lub tsheb, thiab txo qhov hnyav ntawm lub tsheb kom yooj yim rau kev tsav tsheb.Sab hauv ntawm ntau lub tsheb kuj yog ua los ntawm polyurethane, vim nws tshwj xeeb tshaj yog tiv taus dej thiab tuaj yeem tiv thaiv dej deformation ntawm cov khoom dai, ua rau sab hauv ntawm lub tsheb zoo nkauj thiab xis nyob.

5 Kev xaus

Lub teeb yuag tsheb tsim tau dhau los ua ib qho tseem ceeb hauv kev tsim tsheb, thiab tseem yog ib txoj hauv kev los ntsuas qib ntawm kev tsim tsheb thiab lub cim tseem ceeb ntawm cov txheej txheem kev muaj peev xwm.Tsuas yog siv cov ntaub ntawv zoo dua ntawm cov ntaub ntawv polyurethane hauv Tuam Tshoj txoj kev tsim tsheb thiab kev tshawb fawb ntawm cov ntaub ntawv polyurethane yuav pab kom muaj feem cuam tshuam cov fwj, xws li cov teeb meem ntawm kev kub ntxhov ntawm cov log tsheb, uas tseem xav tau kev sib koom tes tshawb fawb thiab kev txhawb nqa ntawm cov cai los ntawm cov kws tshaj lij hauv kev tsim tsheb. kev lag luam, nyob rau hauv kev cia siab hais tias lub domestic tsheb tsim theem yuav tsum tsis tu ncua txhim kho.
