3 Polyurethane elastomer
Nyob rau hauv daim ntawv thov polyurethane elasteane elasteane elasthaners nyob rau hauv tsheb kev tsim, lawv yog feem ntau siv raws li kev poob siab cov ntaub ntawv muaj cov khoom siv lub zog ua kom zoo. Lawv tau siv ua ke nrog kev ua ke siab nrog high- Lub zog caij nplooj ntoo hlav ntawm cov nyhuv ntawm kev ua poob siab ntawm kev nqus cov blocks thiab txhim kho kev nplij siab ntawm cov tsheb. Cov khoom lag luam thiab cov thev naus laus zis.polyurethane khoom siv nrog cov pa hluav taws xob, vim tias tus qauv kawg los tiv thaiv cov tsav tsheb thiab ua lub luag haujlwm tseem ceeb. Lub zog thiab elasticity ntawm lub airbag yuav tsum tau raws li cov cai xaiv, thiab elastic polyurethane yog lub teeb pom zoo tshaj plaws, thiab cov dav hlau feem ntau tsuas yog kwv yees li 200g.
Cov log tsheb yog ib feem ntawm lub tsheb uas tsis tuaj yeem raug tsav. Cov tsheb roj hmab zoo tib yam muaj lub neej pabcuam luv luv thiab tsis tuaj yeem siv rau hauv qhov siab - lub zog ib puag ncig, thiab lawv kuj muaj kev phom sij rau tib neeg kev noj qab haus huv. Yog li ntawd, nws yog qhov yuav tsum tau xaiv cov ntaub ntawv zoo dua, thiab cov ntaub ntawv polyurethane tuaj yeem ua kom tau raws li cov kev xav tau no, thiab tseem muaj cov yam ntxwv ntawm kev nqis peev dua thiab yooj yim thev naus laus zis. Cov log tsheb polyurethane muaj cov cua sov tsis kam thaum ua braking. Qhov no kuj yog vim li cas lawv tsis muaj txwv nyob rau hauv cov ntawv thov tshwj xeeb. Feem ntau, cov log tsheb polyurethane tau muab pov rau hauv ib txheej txheem dej, uas tuaj yeem hloov cov log tsheb sib txawv rau cov yuav tsum sib txawv, yog li cov log tsheb yuav tsis ua tej yam qias neeg thiab muaj xim ua qias tuaj. Kuv vam tias nws tuaj yeem daws tau yav tom ntej. Qhov teeb meem uas cov log tsheb polyurethane tsis yog qhov kub kub tiv thaiv tau zoo dua ua tau kev siv dav dav.
4 Polyurethane Adhesive
Lub hydrogen sib khi ntawm cov polyurethane thiab cov khoom uas yuav tau sib khi yuav txhim kho cov cohesion ntawm cov lwg me thiab txuas ntxiv ua kom muaj zog dua. Cov polyurethane nplaum kuj muaj cov khoom zoo thiab kho tau. Lub polyurethane nplaum muaj cov hmoov av zoo heev thiab cuam tshuam kuj. Nws yog qhov haum rau ntau cov txheej txheem nplaum cov nplaum teb thiab muaj kev yooj yim heev. Cov polyurethane nplaum muaj cov khoom zoo thiab tuaj yeem hloov kho txoj kev sib raug zoo ntawm cov coefficients ntawm thermal expansion. Nws muaj cov nplaum nplaum muaj zog thiab tseem muaj cov haujlwm ua kom zoo thiab poob siab ua haujlwm. Cov khoom siv polyurethane xws li cov cua nplaum tuaj yeem ua tiav kev sib tw zoo ntawm lub tsheb, uas tuaj yeem ua rau lub tsheb lub tsheb, thiab tuaj yeem nce cov hluav taws xob ntau dua thiab yooj yim dua ntawm lub tsheb. Lub zog, nrog rau kev txo qhov hnyav ntawm lub tsheb, yog qhov kom tiv thaiv kev ua kom zoo nkauj ntawm cov ntaub ntawv ntawm lub tsheb, thiab zoo dua ua rau lub sab hauv ntawm lub tsheb zoo nkauj thiab xis nyob.
5 lub ntsiab lus
Lub teeb ci ntawm tsheb tsim tau ua lub ntsiab tseem ceeb ntawm cov tsheb tsim khoom, thiab nws tseem yog qhov txhais tau tias yog ntsuas cov qib ntawm cov tsheb tsim khoom lag luam. Nws yog cov cim tseem ceeb ntawm cov kev siv tshuaj thiab thev naus laus zis. Polyurethane siv nyob rau hauv automobiles los ntawm cov khoom siv polyurethane xws li polyurethane ua npuas thiab polyurethane elastomers. Muaj cov qauv sib txawv. Tsuas yog Tuam Tshoj cov khoom siv polyurethane tau siv nyob rau hauv cov khoom tsim tsheb, thiab tshawb xyuas cov ntaub ntawv polyurethane tau daws cov khoom siv ntsig txog cov log tsheb, xws li cov log tsheb tiv thaiv kub. Qhov no tseem yuav tsum muaj kev tshawb fawb ntawm cov kws tshaj lij kev lag luam thiab kev txhawb nqa uas theem ntawm cov tsheb lag luam hauv tsev yuav txuas ntxiv txhim kho.
