Non-nws yog xim hlau qhov chaw pleev xim rau hauv tsheb thiab lawv cov txuam （1） - Khoom Taw Qhia

Automotive qhov yas hloov thiab damping qhov chaw ua ke Kev muag khoom Lub tshuab yas cov hniav yog zoo ib yam li lwm qhov hlau. Lawv tseem muab faib ua cov khoom siv qis, cov tsho thom khwm, cov kua roj vanish lossis cov tsho tiv no sab saum toj (cov tsho loj sab saum toj yog siv los hloov chaw pib pleev xim / cov varnish). Tus pib yuav siv tau ncaj qha rau thaj chaw kho cov yas substrate, feem ntau yuav tsum muaj cov zaj duab xis tuab txog li 30 μm kom npog tag nrho cov cim ntws thiab qhov tsis xws ntawm qhov chaw ntawm ib feem. Lub epoxy-polyamide ob-tivthaiv yas primer tsuas yog siv rau pem hauv ntej thiab nram qab lub tsheb ntawm cov tsheb tsis sib haum. Txij li cov ntawv bumper feem ntau yog polypropylene, ib qho me me ntawm chlorinated polypropylene tau ntxiv los ua lub hauv paus khoom los txhim kho cov primer. Adhesion. Kuj tseem muaj cov kuab-ua-ib-ob-ntu tivthaiv polyurethane primers rau tsheb bumpers thiab lwm cov yas. Lub hauv paus xim feem ntau yog siv tib yam li cov xim pleev xim rau cov khoom siv rau cov hlau, thiab cov zaj duab xis tuab yog feem ntau 10 txog 15 μm. Cov kua roj vanish yog ua kom hnyav-raws li ob-tivthaiv polyurethane, uas sib txuas nrog polyacrylate thiab polyester nrog polyisocyanate, thiab cov xim pleev xim tuaj yeem ua tiav qhov yuav tsum tau hloov, thiab tseem muaj tshuaj lom neeg kuj thiab cov cuab yeej zoo. Cov varnish zaj duab xis loj feem ntau yuav tsum tau siv li ntawm 35 μm los ua kom muaj xim txaus thiab kom ua tiav qhov ci nrog lub cev. Cov yas monochrome tas kuj siv ob qhov sib xyaw polyurethane system kom ua tiav cov duab sib luag thiab cov kev ua tau zoo raws li lub cev. Qhov kub ntawm cov roj pleev cov yas muaj ntau yam yog ib puag ncig 80 ° C.

Raws li Tuam Tshoj cov tsheb, tshwj xeeb tshaj yog cov tsheb, txhim kho mus rau qhov siab dua, qhov siab dua yuav tsum tso rau qhov kev ua tau zoo ntawm thermal rwb thaiv tsev, shockproof thiab suab-nqus txheej txheej. Qhov no yog siv txhawm rau txhim kho airtightness, txo kev co, txo suab nrov, txhim kho lub tsheb kom zoo thiab tiv taus xeb ntawm lub cev qhov khoob. Lub kaus poom hauv qab yog nyob rau hauv qab ntawm qhov chaw tawm sab hauv, tshwj xeeb yog saum npoo ntawm lub log thiab fender uas raug rau pob zeb nres. Nws yog txheej nrog hnav-tiv taus txheej ntawm 1 mus rau 2 μm tuab, uas tuaj yeem txhim kho qhov kev cuam tshuam thiab tiv taus ntawm kev sib nkag hauv cov khoom hauv qab. Kev yaig, txhim kho nws txoj kev txhim kho corrosion thiab lub neej ntawm lub tsheb. Anti-sonic coatings yog cov qauv tsim kom txo cov suab nrov uas ua los ntawm kev vibration. Xyoo tsis ntev los no, lub tsheb damping txheej feem ntau siv cov txheej txheem tsis pub dawb PVC series txheej ua los ntawm polyvinyl chloride cob (piv txwv li, PVC) yog cov khoom siv tseem ceeb, thiab cov ntsiab lus tsis zoo tuaj yeem ncav cuag 100%. Cov txheej txheej PVC no muaj qhov zoo hardness, elongation, shear lub zog thiab tensile lub zog, thiab tuaj yeem ua tau zoo raws li kev ua tau zoo uas yuav tsum tau ua damping txheej.

Cov txheej txheej uas feem ntau siv thiab cov khoom sib txuam rau cov xov txheej ntawm cov yas muaj cov khoom coj los tiv thaiv corrosion ntawm cov chaw yas thiab tsis tas yuav muaj tshuaj los tiv thaiv xeb. Yog li ntawd, lub hom phiaj ntawm cov yas txheej siv yog tsom rua qhov kev ua kom zoo nkauj zoo nkauj. Sij hawm dhau los, cov tshuaj pleev xim tau ntxiv rau hauv cov tswv cuab ntawm plastics. Cov txheej txheem, nrog qhov ua kom zoo nkauj ntxiv ntawm cov tib neeg, tsis tuaj yeem ua raws li cov kev xav tau ntawm kev siv, thiab yog li ntawd yuav tsum tau ua cov khoom lag luam ntxiv theem ob ntxiv kom ua tiav cov laj thawj nram qab no: kom ua rau saum npoo ntawm cov khoom yas muaj ntau yam xim; npog cov txheej txheem ntau lawm Kev Kos thiab lwm yam tsis xws luag; txhim kho kev ntxhib los mos ntawm cov txheej txheem yas, xws li kev tsim hlau thiab ntoo; txhim kho cov yam ntxwv ntawm cov khoom yas, xws li muaj tawv tawv, tiv thaiv tsis kam, thiab lwm yam.; txhim kho cov tshuaj lom neeg cov tshuaj tiv thaiv ntawm cov khoom lag luam yas, xws li huab cua tsis kam, nplaim taws rov qab, hnyav tsis kam, thiab lwm yam.; txhim kho cov khoom siv lub cev ntawm cov khoom yas, xws li hluav taws xob conductivity, antistatic thaj chaw, thiab lwm yam.; luam ntawv ntawv, duab, cim lag luam, thiab lwm yam.
