Daim txhuam cev Profile thiab Foamed Parts: Qhov kawg daws nrog Anti- suab nrov, Huab cua-resistant EPR Raw Roj Hmab
Taw Qhia
Los ntawm qhov kev xav ntawm cov kws tshaj lij roj hmab, kev tiv thaiv suab nrov, huab cua-resistant ethylene propylene roj hmab-EPR raw roj hmab-muaj cov tshuaj zoo heev rau daim ntaub ntawv foob, tshwj xeeb tshaj yog nyob rau hauv daim txhuam cev profile thiab foamed qhov chaw. Cov roj hmab no muaj lub siab Mooney viscosity, siab ENB cov ntsiab lus, ceev curing ceev, thiab cov neeg kho tshuab siab uas ua kom muaj kev ua haujlwm ntev thiab ua haujlwm ntev.
High Mooney Viscosity
EPR raw roj hmab nthuav tawm lub siab Mooney viscosity, uas ua kom cov txheej txheem zoo thiab molding zog. Qhov viscosity no tso cai rau kev yooj yim ntawm kev tuav thiab kev tswj xyuas thaum lub sijhawm tsim khoom, ua kom muaj kev tsim tawm thiab sib xws hauv kev tsim khoom. Lub siab viscosity kuj pab txhawb kev txhim kho kev sib khi, ua rau nws tsim nyog rau ntau daim ntawv thov foob.
High ENB Cov Ntsiab Lus
EPR cov roj hmab nyoos muaj cov nyiaj ntau ntawm ENB (ethylene-propylene-butylene), uas ua rau nws cov khoom tshwj xeeb. ENB ntxiv qhov yooj thiab toughness rau cov roj hmab, txhim kho nws cov khoom siv kho tshuab. Cov ntsiab lus ENB siab kuj ua rau cov roj hmab tiv taus huab cua, ua kom lub neej ntev hauv kev siv sab nraum zoov.
Fast Curing Speed
EPR raw roj hmab nta lub nrawm nrawm, uas txhais tau tias nws tuaj yeem ua tiav sai yam tsis muaj kev txi zoo. Qhov ceev curing ceev ua rau cov tuam txhab ua tiav lub sijhawm luv luv, txhim kho cov khoom tsim tau, thiab txo cov nqi tsim khoom. Tsis tas li ntawd, cov roj hmab txoj kev kho mob ceev ceev ua kom muaj kev ruaj ntseg thiab txhim khu kev qha thaum kev teeb tsa.
High Mechanical Properties
EPR raw roj hmab qhia cov khoom siv kho tshuab siab, suav nrog lub zog tensile, modulus, thiab hardness. Cov khoom no xyuas kom meej tias cov roj hmab tsim nyog rau ntau daim ntawv thov sealing qhov twg yuav tsum muaj cov ntsaws ruaj ruaj thiab ruaj khov. Cov khoom siv hluav taws xob ntawm EPR cov roj hmab nyoos ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov foob hauv daim txhuam cev profile thiab cov khoom foamed.
Nyob rau hauv cov ntsiab lus
EPR raw roj hmab lub siab Mooney viscosity, siab ENB cov ntsiab lus, ceev curing ceev, thiab siab mechanical zog ua rau nws ib tug zoo tagnrho cov ntaub ntawv rau foob daim ntaub ntawv nyob rau hauv daim txhuam cev profile thiab foamed qhov chaw. Cov roj hmab zoo heev sealing kev ua tau zoo thiab huab cua tsis kam ua kom muaj kev ua haujlwm ntev thiab ua haujlwm ntev hauv ntau daim ntawv thov sealing. Qhov ceev curing ceev ua rau cov tuam txhab ua tiav lub sijhawm luv luv thiab txhim kho cov khoom lag luam, txo cov nqi tsim khoom thaum tswj xyuas qhov zoo. Cov khoom siv kho tshuab ua kom ntseeg tau tias cov roj hmab tsim nyog rau ntau daim ntawv thov sealing uas yuav tsum tau muaj zog thiab ruaj khov. Daim txhuam cev profile thiab foamed qhov chaw nrog EPR raw roj hmab muab cov kev daws teeb meem zoo tshaj plaws rau kev sib khi daim ntaub ntawv uas yuav tsum tau tiv thaiv lub suab nrov thiab huab cua tsis kam.
