Thermal conductivity
Optimally txheej txheej thermal conductive muab tub lim ua tau siab thermal conductivity
Peb tswj cov kev taw qhia ntawm anisotropic thermal conductive muab tub lim los ua kom muaj cua sov tawm txoj hauv kev, ua tiav cov thermal conductivity thiab softness.Tsis tas li ntawd, peb cov khoom sib xyaw ua ke yog tsim los ntawm cov khoom siv hluav taws xob nkaus xwb thiab cov khoom siv tsis muaj siloxane, txo qhov kev pheej hmoo ntawm kev cuam tshuam cov khoom hluav taws xob mus rau qib qis heev.
Thermal rwb thaiv tsev
Ua npuas ncauj muaj ntau cov huab cua nrog tsawg convection uas ua rau tsis tshua muaj thermal conductivity thiab superior thermal rwb thaiv tsev kev ua tau zoo
Kaw cov hlwb hauv npuas txwv cov huab cua convection, ua kom sov me ntsis, uas muab thermal rwb thaiv tsev zoo heev.Sib txawv ntawm cov iav ntaub plaub thiab cov ua npuas ncauj nruj, ua npuas ncauj yog qhov hloov tau yooj yim dua thiab yooj yim rau nruab.Yog li ntawd, nws yog tsim rau insulators rau sau qhov chaw me me hauv tsev thiab ntau yam tshuab.
Thaum tshav kub kub Resistance
Nrog rau cov cua kub zoo heev, polypropylene resin muaj tsawg thermal shrinkage txawm nyob rau hauv qhov kub thiab txias
Tus nqi sawv cev ntau npaum li cas cov npuas hloov pauv loj ntawm qhov sib txawv ntawm qhov kub thiab txias thaum rhuab yam tsis muaj kev quab yuam sab nraud.Thaum polyethylene ua npuas ncauj deforms thaum rhuab mus rau 80 ° C los yog siab dua, polypropylene ua npuas ncauj muaj zoo heev tshav kub kuj nrog ib tug shrinkage tus nqi ntawm 3% los yog tsawg dua txawm nyob rau ntawm 140 ° C.
Sealing Ability Smoothness Flexibility
Sealing Muaj peev xwm
Nrog nws yooj yim, lub npuas seals tsis sib xws los yog ntse nto
Cov cuab yeej sealing ntawm lub sealer xws li tapes yog heev cuam tshuam tsis tsuas yog los ntawm cov khoom ntawm cov khoom siv, tab sis kuj los ntawm nws cov kev sib raug zoo ntawm lub cev nrog lub uneven nto ntawm adherend.Cov khoom siv nrog kev hloov pauv siab tshem tawm qhov tsis sib xws nrog cov adherend thiab paub txog kev ua haujlwm siab sealing.
Sib piv nrog lwm cov ntaub ntawv ntawm cov khoom sib khi
Ua npuas ncauj seals qhov chaw tsis sib xws thiab sau qhov khoob hauv lub tsev
Smoothness
Ib qho yooj yim thiab huv si saum npoo piv rau tshuaj lom neeg crosslinked ua npuas ncauj, haum rau adhesion thiab txheej
Electron beam crosslinking accelerates electrons nrog high voltage thiab emits lawv mus rau nplooj ntawv.Cov nqaj hluav taws xob sib npaug thiab ruaj khov nkag mus los ntawm txhua daim ntawv, ua rau muaj kev sib koom ua ke ntau dua li lwm txoj hauv kev.Nws tso cai rau txawm foaming uas tsim ib tug du nto txheej haum rau adhesion thiab txheej.
Yooj yim
Resin's intrinsic softness thiab kaw-cell qauv muab tsim nyog elasticity thiab cushioning
Lub cell ntawm electron-crosslinked nplooj ntawv yuav muaj inflate nyob rau hauv cov txheej txheem tom qab foaming.Cells nrog ntau lub sijhawm nthuav dav tsim cov qauv kaw-cell uas txhua lub hlwb raug cais los ntawm phab ntsa.Lub kaw-cell qauv muaj qhov tshwj xeeb cushioning thiab shock absorbing.Muaj kev poob siab zoo heev txawm tias me me thickness, IXPE / PP nplooj ntawv yog siv los ua pob cushioning rau precision instruments.
