Kev laus ntawm cov ntaub ntawv rwb thaiv tsev ncaj qha cuam tshuam rau kev ntseeg tau thiab kev pabcuam lub neej ntawm cov khoom siv hluav taws xob thiab hluav taws xob.

Tsis zoo li lwm yam ntaub ntawv, xws li hlau, cov khoom ntawm insulating cov ntaub ntawv yog heev yooj yim mus hloov lub sij hawm.Hauv kev ua haujlwm ntev lossis khaws cov khoom siv hluav taws xob thiab hluav taws xob, nyob rau hauv qhov kev txiav txim ntawm ntau yam kev laus, cov ntaub ntawv insulating, tshwj xeeb tshaj yog cov organic insulating cov ntaub ntawv, yuav undergo ib tug series ntawm tshuaj (degradation, oxidation thiab crosslinking, thiab lwm yam) hloov, ua rau. Lub decomposition ntawm cov ntaub ntawv insulating, tiam ntawm cov tsis tshua muaj molecular volatiles, cov tsos ntawm pores, kua viscosity hloov, nto ntawm cov khoom yog nplaum, nkig, carbonized, polarity nce, discoloration, tawg thiab deformation, yog li ntawd irreversible hloov nyob rau hauv kev ua tau zoo tshwm sim. , maj mam poob cov yam ntxwv ua haujlwm qub, qhov tshwm sim no hu ua kev laus.

Kev laus ntawm cov ntaub ntawv rwb thaiv tsev muaj xws li thermal aging, atmospheric aging, hluav taws xob aging thiab mechanical aging.Thermal aging feem ntau yog lub sij hawm ntev ua ke ntawm cov cua sov thiab oxygen ntawm cov ntaub ntawv insulating.Atmospheric aging feem ntau yog lub sij hawm ntev ua ke ntawm lub teeb (tshwj xeeb tshaj yog ultraviolet), oxygen, ozone, dej thiab lwm yam tshuaj.Kev laus hluav taws xob feem ntau yog lub sijhawm ntev ua ke ntawm hluav taws xob teb, cua sov thiab oxygen.Mechanical aging feem ntau yog kev sib koom ua ke ntawm txhua yam quab yuam, cua sov thiab oxygen.Tsis tas li ntawd, cov hluav taws xob hluav taws xob siab, cov teeb meem lom neeg thiab cov kab mob microbial kuj yog qhov tseem ceeb uas tsis tuaj yeem tsis quav ntsej.Ntau yam dawb radicals hauv kev laus ua lub luag haujlwm tseem ceeb hauv kev loj hlob ntawm kev laus.

XINXING Rwb thaiv tsev FR4 EPOXY Laminated Sheet

Cov hauv qab no tsom rau cov thermal aging thiab kub tsis kam qib ntawm cov ntaub ntawv insulating.Qhov kub thiab txias yog qhov tseem ceeb tshaj plaws uas cuam tshuam rau kev laus ntawm cov khoom siv insulating.Rau ntau yam rwb thaiv tsev, qhov ntsuas kub ntawm cov ntaub ntawv rwb thaiv tsev thiab cov qib kub tsis kam ntawm cov rwb thaiv tsev yuav tsum raug soj ntsuam raws li txoj kev ntsuas kev laus.Saib [EC60216 standard].Qhov ntsuas kub tsis kam yog tsim los ntawm ob qhov ntsuas, qhov ntsuas kub thiab qhov ntsuas kub ib nrab ntawm lub neej.Qhov ntsuas kub yog qhov ntsuas kub ntawm Celsius sib haum rau lub neej teev tseg (feem ntau yog 20,00h) nyob rau hauv qee yam kev sim.Qhov kub sib thooj rau ib nrab lub neej yog lwm qhov ntsuas kub, thiab qhov sib txawv ntawm ib nrab lub neej yog qhov sib txawv ntawm ob qhov ntsuas kub.Cov qib sib txawv ntawm cov cua sov ua haujlwm ntawm lub cev muaj zog lossis kev rwb thaiv tsev yuav tsum xaiv qhov sib xws ntawm qhov kub thiab txias,Jiujiang Xinxing rwb thaiv tsev khoomKev tsim cov cua sov ua haujlwm qib los ntawm qib A mus rau qib C (kub kub tsis kam ntawm 120 degrees txog 200 degrees) epoxy iav ntaub laminate, txhua yam khoom tuaj yeem muab cov ntaub ntawv IEC sib xws, koj tuaj yeem tau txais txiaj ntsig los xaiv, txais tos sab laj.
