Automotive cov ntaub ntawv sab hauv raug cov hnub ci hnyav yuav tsum tiv thaiv ob daim duab -oxidative degradation thiab thermal volatile tawm-gassing. Engineering-qib microfiber suede integrates hindered amine teeb stabilizers (HALS) thiab DMF-dawb polyurethane ib txhij ua kom tiav Ntau dua los yog sib npaug rau Qib 4 colorfastness nyob rau hauv Xenon arc raug thiab nruj VDA 277 VOC ua raws.
Solar Load Mechanics: Yees duab-Oxidation thiab VIAQ Ua raws
Thaum lub tsheb cabins raug rau lub hnub ci hluav taws xob ncaj qha, dashboard thiab rooj zaum saum npoo kub ntau tshaj 85 degree. Qhov huab cua kub thiab ultraviolet load no ua rau ob qho kev puas tsuaj loj hauv cov txheej txheem hluavtaws tawv: polymer saw scission (ua rau saum npoo tawg) thiab tawm sai sai - gassing ntawm residual kuab tshuaj (ua rau lub tshuab cua fogging thiab cov ntxhiab tsw ntxhiab hauv tsev).
To engineer ibAnti-aging tsheb sab hauv tawv, lub hauv paus polymer chemistry yuav tsum tau hloov kho. Peb cov kab ntau lawm siv 100% dej-yug, DMF-dawb polyurethane coagulated hauv hiav txwv- kob polyethylene terephthalate (PET) matrix. Thaum lub sij hawm slurry compounding theem, tshwj xeeb UV absorbers thiab HALS raug faib volumetrically thoob plaws hauv cov resin. Qhov no tiv thaiv UV photons los ntawm kev rhuav tshem cov polyether bonds, tswj cov khoom ntawm cov qauv elasticity (Bally flexing> 100,000 cycles) thiab ua kom lub tsheb sab hauv huab cua zoo (VIAQ) emissions tseem tsawg dua los yog sib npaug rau 10 mg / kg txawm nyob rau hauv kev kub ntxhov tas li.

Kev ntsuam xyuas cov ntsiab lus ntawm fading lossis tsw tsis raug cai hauv automotive QA. Cov ntaub ntawv tshwj xeeb hais txog kev txheeb xyuas ntau yam siv cov huab cua nrawm nrawm thiab cov roj chromatography. Cov matrix hauv qab no sib piv cov qauv kev lag luam PU tiv thaiv peb cov tshuab tsim tsheb micro suede.

Rau qhov ncajLag luam wholesale auto upholsterytus neeg muag khoom, aligning lub substrate thickness thiab UV pob rau cov khoom siv hauv tsev tshwj xeeb yog qhov yuav tsum tau ua kom tsis txhob muaj kev lav phib xaub.
- Instrument Panels (Dashboards):Ua qhov siab tshaj plaws ncaj qha UV index thiab cua sov so. Cov khoom siv yuav tsum nthuav tawm cov thermal shrinkage ntawm <1.5% ntawm 120℃los tiv thaiv ntug curling thiab delamination los ntawm lub hauv paus ABS / PC substrate.
- Steering Wheels:Kev txom nyem los ntawm kev sib xyaw UV hluav taws xob thiab lactic acid hloov ntawm tib neeg txhais tes. Lub DMF-dawb matrix tiv thaiv cov tshuaj cleavage, thaum qhov sib sib zog nqus -vat disperse dyeing tiv thaiv dye tsiv teb tsaws mus rau cov neeg tuav tes.
- Tsheb Rooj:Yuav tsum muaj peev xwm tensile siab nyob rau hauv thermal load. Lub 3D electrospunMicrofiber SuedeCov tub ntxhais sib npaug faib cov neeg nyob hauv qhov hnyav, tiv thaiv qhov chaw hauv cheeb tsam ncab (puddling) feem ntau pom nyob rau hauv degraded standard vinyl tom qab 24 lub hlis ntawm kev siv teb.

Cov lus nug nquag
Q: Yuav ua li cas yog UV tsis kam kuaj rau automotive microfiber?
A: Laboratories siv Xenon arc weathering testers tom qab SAE J2412 lossis ISO 105-B06 raws tu qauv. Cov khoom yog raug tswj los ntawm irradiance, tshav kub, thiab humidity cycles. Tom qab raug xim fading yog ntsuas ntau ntawm spectrophotometer thiab muab qhab nia tiv thaiv tus qauv greyscale (Qib 1 txog 5).
Q: Vim li cas cov rooj zaum hauv tsheb puas tawg nyob rau lub hnub ntev?
A: Tus qauv hluavtaws tawv absorbs siab -lub zog UV photons, ua rau cov duab -oxidative degradation uas cleaves polymer chains. Concurrently, thermal tshav kub accelerates evaporation ntawm cov tshuaj plasticizers. Qhov kev poob ob npaug no tawm ntawm cov polymer matrix nruj, nkig, thiab ua rau cov neeg kho tshuab nrawm nrawm.
Q: VDA 277 yog dab tsi thiab vim li cas nws tseem ceeb rau UV- cov tawv nqaij?
A: VDA 277 yog German automotive standard ntsuas tag nrho VOC emissions. Thaum cov ntaub ntawv kub nyob rau hauv ncaj qha UV / hnub ci load, residual solvents vaporize sai. Ua raws li microfiber yuav tsum sau tag nrho cov pa roj carbon emissions qis dua 30 ugC / g kom tiv thaiv cov ntxhiab tsw ntxhiab hauv tsev thiab sab hauv fogging.
