Lub tsheb bumper yog ib qho ntawm cov khoom siv kho kom zoo nkauj loj ntawm lub tsheb. Nws muaj peb lub luag haujlwm tseem ceeb: kev nyab xeeb, kev ua haujlwm thiab kho kom zoo nkauj.
Cov yasyog dav siv nyob rau hauv kev lag luam automotive vim lawv lub teeb yuag, kev ua tau zoo, kev tsim khoom yooj yim, corrosion kuj, kev cuam tshuam tsis kam, thiab cov qib loj ntawm kev tsim kev ywj pheej, thiab lawv suav nrog kev nce qib ntawm cov khoom siv tsheb. Tus nqi ntawm cov yas siv nyob rau hauv ib lub tsheb tau dhau los ua ib qho ntawm cov qauv ntsuas kev txhim kho ntawm lub teb chaws kev lag luam tsheb. Tam sim no, cov yas siv los tsim lub tsheb hauv cov teb chaws tsim tau mus txog 200kg, suav txog li 20% ntawm tag nrho cov tsheb.
Bumper cov ntaub ntawv feem ntau muaj cov cai hauv qab no: kev cuam tshuam zoo thiab huab cua tsis zoo. Cov xim zoo adhesion, fluidity zoo, kev ua haujlwm zoo, thiab tus nqi qis.
Raws li qhov no, PP cov ntaub ntawv yog undoubtedly tus nqi-zoo xaiv. Cov khoom siv PP yog cov khoom siv dav dav nrog kev ua haujlwm zoo. Txawm li cas los xij, PP nws tus kheej muaj qhov ua haujlwm tsis zoo ntawm qhov kub thiab qhov cuam tshuam, tsis hnav-tiv taus, yooj yim rau hnub nyoog, thiab tsis muaj qhov tsis zoo. Yog li ntawd, hloov PP feem ntau yog siv rau tsheb bumper ntau lawm. Khoom siv. Tam sim no, tshwj xeeb polypropylene tsheb bumper cov ntaub ntawv feem ntau yog ua los ntawm PP raws li cov khoom tseem ceeb, thiab ib qho kev faib ua feem ntawm roj hmab los yog elastomer, inorganic muab tub lim, xim masterbatch, additives thiab lwm yam ntaub ntawv yog ntxiv los ntawm kev sib tov thiab ua.
Yog li yuav ua li cas nrog cov ntaub ntawv sprue, cov ntaub ntawv khiav thiab cov khoom tsis raug tsim thaum lub sij hawm txhaj tshuaj molding txheej txheem ntawm lub tsheb yas bumpers? Cia nws musZAOGE lub zog-txuag thiab cov khoom-txuag cov khoom siv rov ua dua tshiab.Tom qab cov khoom siv sprue thiab cov khoom siv khiav yog kub crushed los ntawmyas crusher, lawv tuaj yeem muab ntxiv rau cov ntaub ntawv tshiab los txhaj cov khoom ua ke. Cov khoom tsis raug tuaj yeem raug crushed nyob rau hauv ib tug centralized yam thiab ua tiav rau hauv cov ntaub ntawv rau theem nrab ua thiab ces txhaj molded.
