Hauv kev tsim tsheb thiab kev hloov kho tom qab kev lag luam, kev kho cov txheej txheem rau sab nrauv xws li sab strips, log arches, thiab spoilers tau hloov tag nrho los ntawm thaum ntxov "mechanical fastening" mus rau "adhesive bonding." Ntawm cov no, acrylic ua npuas ncauj daim kab xev tau dhau los ua tus qauv kev xaiv rau OEMs thoob ntiaj teb vim nws qhov kev ua haujlwm tsis zoo.
Zoo heev Viscoelasticity: Ib qho "Shock Absorber" rau Thermal Expansion thiab Contraction
Automotive sab nrauv (feem ntau yog ua los ntawm ABS, PP, los yog EPDM yas) muaj qhov sib txawv coefficients ntawm thermal expansion piv rau lub cev cov khoom hlau. Nyob rau hauv kev sib hloov ntawm lub caij ntuj sov tshav raug tshav kub (txog 80 degree) thiab lub caij ntuj no txias (mus txog -40 degree), qhov sib txawv ntawm cov ntaub ntawv uas yuav ua rau muaj kev ntxhov siab loj.
Technical Principple:
Acrylic ua npuas ncauj daim kab xev tsis yog ib txheej ntawm cov nplaum; Nws yog viscoelastic tag nrho.
Engineering Advantages:
Thaum muaj kev ntxhov siab, cov tub ntxhais ua npuas ncauj absorbs thiab disperses lub zog los ntawm nws tus kheej feeb deformation, tiv thaiv daim kab xev los ntawm hardening los yog trim los ntawm detaching vim brittleness.
Perfect Surface Compensation: 100% Siv Tau Zoo
Automotive lub cev tsis zoo tag nrho; curved nto thiab microscopic roughness yog cov yeeb ncuab ntawm adhesion. Ib txwm nyias nyias ob -ib sab tapes tsis tuaj yeem sau cov qhov khoob no, ua rau thaj chaw tiv tauj tsis txaus.
Wetting Properties:
Acrylic ua npuas ncauj muaj cov khoom zoo rheological; nyob rau hauv siab, cov nplaum "ntub" thiab sau cov micropores ntawm qhov chaw zoo li cov kua.
Sealing:
Qhov no 100% adhesion tsis tsuas yog txhim kho rub- tawm lub zog tab sis kuj tsim lub ntuj thaiv, tiv thaiv ya raws, ntsev tsuag, thiab hmoov av los ntawm kev nkag mus rau qhov sib txuas, yog li tiv thaiv xeb ntawm lub tsheb lub cev.
Durability nyob rau hauv hnyav ib puag ncig: Kev lag luam Standard hauv 2026
Automotive sab nrauv qhov chaw ntsib qhov kev thov hnyav heev. High - zoo acrylic ua npuas ncauj daim kab xev yuav tsum xeem dhau cov nram qab no nruj kev ntsuam xyuas:
Peel Strength Test:
Xyuas kom meej tias cov spoiler lossis sab moldings yuav tsis tev tawm nyob rau hauv siab -ceev cua tsis kam.
Solvent Resistance:
Cov qauv nplaum tseem nyob ruaj khov txawm tias tom qab sib cuag nrog cov kua ntxuav tsheb, roj av, lossis txoj kev de-icing ntsev.
Ntev -Tsev Kawm Kev Laus:
Simulates tshaj 10 xyoo ntawm kev tshav ntuj sab nraum zoov, kom tsis txhob yellowing los yog embrittlement.
Yuav ua li cas kom ntseeg tau tias daim ntawv cog lus yeej tsis poob?
Raws li tus kws tshaj lij kev daws teeb meem, peb pom zoo kom ua raws li "Clean-Prime-Xovxwm" peb- cov txheej txheem hauv daim ntawv thov:
Ntxuav:
Ntxuav saum npoo nrog 50% isopropyl cawv aqueous tov kom tshem tawm cov roj thiab av.
Prime:
Rau cov khoom siv hluav taws xob tsawg (LSE) xws li PP thiab EPDM, yuav tsum siv cov khoom tshwj xeeb adhesion.
Xovxwm:
Acrylic daim kab xev yog siab -sensitive (PSA), thiab tsawg kawg yog 15 psi (100 kPa) ntawm siab yuav tsum tau siv tom qab sib txuas.
Mus rau Lub Neej Yav Tom Ntej
Raws li qhov xav tau ntawm kev txo qhov hnyav hauv lub tsheb tshiab lub zog nce, tshem tawm cov khoom siv hlau hnyav tau dhau los ua ib qho qauv.Acrylic ua npuas ncauj daim kab xevtsis tsuas yog muab txoj kev sib txuas ua kom muaj zog thiab zoo nkauj dua, tab sis kuj ua tiav qhov hnyav txo thiab kev tiv thaiv corrosion rau lub tsheb lub cev los ntawm kev txo qhov drilling.
