Polyethylene ua npuas ncauj daim kab xev yog lub siab- cov khoom siv nplaum nplaum uas muaj qhov kaw- xov tooj ntawm tes- txuas polyethylene core coated ntawm ob sab nrog hnyav lossis hloov acrylic nplaum. Nws ua rau cov neeg kho tshuab kam rau siab txog li 3.0 hli thiab nqus lub zog kinetic los ntawm viscoelastic deformation, muab lub foob hermetic tiv thaiv ya raws, plua plav, thiab kev ntxhov siab.
Viscoelastic Zog Dissipation Mechanics
Lub dampening efficiency ntawm pe npuas ob sab daim kab xev cia siab rau nws kaw -cell polymeric matrix. Nyob rau hauv kev cuam tshuam loads, cov huab cua nyob rau hauv discrete cellular qauv compresses elastically thaum polyethylene polymer chains undergone kev sib txhuam. Qhov compression deflection no tso cai rau cov tub ntxhais kom nqus tau cov kev cuam tshuam txhua yam yam tsis muaj kev sib tsoo mus tas li, tswj qhov kev ruaj ntseg nyob rau hauv kev ntxhov siab tsis tu ncua. Tsis tas li ntawd, cov lus teb viscoelastic attenuates cov qauv kev co thiab txo cov kev ntxhov siab ntawm cov khoom sib txuas, tiv thaiv kev sib koom ua ke los ntawm kev sib koom ua ke thermal Expansion Coefficients (CTE) hauv ntau - cov khoom sib dhos.
Conformability thiab Surface Tolerance Compensation
Kev sib koom ua ke feem ntau nthuav tawm qhov sib txawv ntawm qhov sib txawv vim kev ua haujlwm siab, qhov roughness, lossis thermal expansion, qhov twg cov txheej txheem nyias zaj duab xis tapes tsis ua haujlwm thiab ua rau muaj kev ntxhov siab hauv cheeb tsam. Ob chav coated polyethylene ua npuas ncauj daim kab xev muab compressible bulk nrog thicknesses li ntawm 0.2 hli mus rau 3.0 hli, tso cai rau cov nplaum txheej kom ua tiav nto ntub dej - tawm thoob plaws uas tsis yog -planar substrates thiab xyuas kom meej ib tug zoo sib xws cheeb tsam thiab kev nyuaj siab faib thoob plaws hauv tag nrho cov kab.
Technical Performance Specifications
Muaj-qib polyethylene ua npuas ncauj daim kab xev formulations feature kaw -cell PE ua npuas ncauj cab kuj ua ke nrog hnyav los yog acrylic siab-sensitive nplaum tshuab. Raws li ASTM D3652 tus qauv, tag nrho cov thickness ntawm 0.2 hli mus rau 3.0 hli (8 mus rau 120 mil), muaj nyob rau hauv cov qauv dub thiab dawb formulations. Cov khoom siv qhia txog 180℃tev adhesion rau stainless hlau ntau dua los yog sib npaug rau 15 N / 25mm (ntau dua lossis sib npaug li 53 oz / nti) raws li PSTC-101 thiab ASTM D3330 kuaj, nrog rau qhov zoo li qub shear tuav lub zog tshaj 24 teev nyob rau hauv ib qho 1 nti x 1 inch ntawm 2 3℃load. Kev ua haujlwm tsis tu ncua ntawm kev ua haujlwm thermal ncua ntawm -20℃mus rau +120℃(-68℃F txog +248℃F).
Substrate Compatibility thiab Environmental Resistance
Acrylic adhesive chemistry engineered rau ob sab polyethylene daim kab xev qhia cov tshuaj tiv thaiv siab tiv thaiv plasticizers, roj, UV raug, thiab ib puag ncig kev laus. Nws ua tiav daim ntawv cog lus nrawm tsim- nce rau ntawm High Surface Energy (HSE) substrates xws li stainless hlau, aluminium, thiab iav, thaum tshwj xeeb sib txawv xa tawm siab pib tack (Ball Test) thiab shear tuav ntawm Low Surface Energy (LSE) cov ntaub ntawv zoo li Polypropylene (PP), ABS, thiab automotive clear coats. Tsis tas li ntawd, qhov tsis yog -kev sib txuas ntawm cellular matrix thaiv cov dej nkag thiab cov plua plav nkag, ua tau raws li IP6X sealing qauv raws li qhov sib piv compression kom raug.
Cov ntawv thov kev lag luam & Precision hloov dua siab tshiab
Hauv kev tsim tsheb, xaiv ob tog ua npuas ncauj mounting daim kab xev automotive specification muab ntev - lub sij hawm tsis kam rau thermal cycling, txoj kev vibrations, thiab siab - siab washdowns nyob rau sab nrauv thiab sab hauv trim daim ntaub ntawv, nrog rau cov cim mounting, rocker panels, log hnyav txuas, thiab sab lub cev moldings. Nyob rau hauv cov khoom siv hluav taws xob, nws muab cov duab sib txuas, kho lub lens, lub roj teeb pob cushioning, thiab sab hauv module sealing tiv thaiv tee thiab mechanical shocks, thaum muaj kev lag luam siv nws rau kev kho vaj huam sib luag kho kom zoo nkauj, membrane keyboards, thiab HVAC duct dampening.
Rau cov txheej txheem sib dhos tsis siv neeg, precision tuag- txiav qhov siab ntev hauv +/-0.1 hli tuaj yeem ua tiav siv kev hloov pauvob sab PE ua npuas ncauj daim kab xev.
