Yuav ua li cas txhim kho qhov cuam tshuam toughness ntawm peroxide vulcanizate?

Niaj hnub no los muab cov lus qhia luv luv rau koj yuav ua li cas txhawm rau txhim kho qhov cuam tshuam toughness ntawm peroxide vulcanizate! Sulfur hmoov vulcanization tswj system, peroxide vulcanization tswj system thiab epoxy resin vulcanization kev tswj qhov system muaj ntau nyob rau hauv zus tau tej cov roj hmab thiab yas khoom nrog recycled roj hmab, nyob rau hauv uas cov recycled roj hmab vulcanization nrog peroxide vulcanization muaj zoo kub kuj, me me shrinkage deformation, thiab yog tsis yooj yim rau sab saum toj dawb, tab sis qhov cuam tshuam toughness ntawm vulcanization roj hmab xws li tensile zog thiab ruaj elongation hauv av kev nyuaj siab yog tsawg; Txhawm rau txhim kho qhov cuam tshuam ntawm cov tawv nqaij ntawm peroxide-vulcanized roj hmab thiab txhim kho lub zog ntawm cov khoom siv roj hmab, cov tuam ntxhab ntawm cov khoom siv roj hmab tuaj yeem siv ob txoj hauv qab no:
1. Xaiv peroxide / sulfur hmoov thiab siv cov txheej txheem tswj:
Tsis zoo li vulcanizates ntawm peroxide vulcanizate tswj qhov system, cov vulcanizates rov ua dua tshiab ntawm cov tshuaj sulfur hmoov vulcanizate tswj lawv muaj lub zog tensile siab, hnav tsis kam thiab cov khoom muaj zog. Yog li ntawd, hauv kev tsim thiab tsim khoom, cov khoom siv roj hmab rov siv tau tuaj yeem siv peroxide thiab sulfur hmoov thiab txhim kho cov yam ntxwv ntawm vulcanization thiab lub cev muaj zog ntawm cov yas pellets. Cov khoom siv roj hmab rov ua dua tshiab muaj cov roj hmab siv roj hmab, cov log tsheb siv roj hmab, cov roj hmab siv roj hmab butyl recycled roj hmab, nitrile recycled roj hmab, EPidiene propylene diene recycled roj hmab thiab PP recycled roj hmab, tsis yog tib hom recycled roj hmab vulcanization yam ntxwv tsis zoo ib yam, cov khoom siv roj hmab recycled yuav tsum xaiv hom peroxide zoo, tswj cov peroxide thiab sulfur hmoov zoo thiab siv qhov kev faib ua feem.
2. Ntxiv coupling pab:
Nyob rau hauv cov qauv ntawm cov khoom siv roj hmab recycled nrog peroxide vulcanization, ntxiv tshuaj lom neeg nrog optically active polyfunctional pawg isomerism thiab tsis tshua muaj txheeb ze molecular hnyav, xws li TMPTA, TMPTAMA, EGDA, EGDMA, PDM, ZDA, ZDMA, thiab lwm yam., tuaj yeem txhim kho cov tshuaj crosslinking. efficiency ntawm vulcanization. Txhim kho lub zog ntawm regenerated vulcanizate thiab qhov zoo tshaj plaws Performance index tus nqi ntawm qhov ruaj khov extension hauv av kev nyuaj siab; Lub zog tensile thiab resilient compressive lub zog ntawm peroxide vulcanizates tuaj yeem txhim kho tau zoo los ntawm kev siv TAC, TAIC thiab lwm yam khoom siv tshuaj sib txuas sib txuas. Thaum cov roj hmab rov ua dua yog vulcanized nrog peroxide, yog tias lub cev muaj zog muaj zog xws li lub zog tensile thiab ruaj khov txuas ntxiv hauv av kev ntxhov siab yog txhim kho raws li thiab nrog cov hmoov sulfur, cov ntxhiab tsw ntawm cov roj hmab rov ua dua vulcanized roj hmab yuav nthuav dav nrog kev siv cov tshuaj sulfur. hmoov; Thaum ntxiv cov kev pab cuam txuas mus rau regenerated roj hmab peroxide vulcanization tswj system los txhim kho qhov cuam tshuam toughness ntawm regenerated roj hmab vulcanization, qhov ntxiv ntawm coupling pab yuav ua rau muaj kev puas tsuaj rau tag nrho cov txheej txheem ntawm regenerated roj hmab vulcanization thiab vulcanization kev nyab xeeb yam, yog li cov chaw tsim tshuaj paus ntawm regenerated roj hmab cov khoom. yuav tsum tau tswj kom muaj txiaj ntsig zoo ntawm cov hmoov sulfur thiab hom thiab tus nqi ntawm kev sib txuas ntawm kev pabcuam thaum lub sijhawm ua haujlwm. Thaum tsim nyog, ib qho me me ntawm leej faj tuaj yeem siv los muab lub cev kom muaj qhov sib npaug ntawm ntau qhov ntsuas qhov tseem ceeb ntxiv rau kev txhim kho qhov cuam tshuam ntawm cov khoom siv roj hmab vulcanizate.
Raws li qhov xwm txheej ib txwm muaj, EPDM rov siv roj hmab raws li lub pob txha ntawm kev tsim cov khoom siv roj hmab thiab cov khoom yas, cov khoom siv tshuaj peroxide vulcanization yuav muaj ntau dua, thiab tsim nyog tshwj xeeb coupling tus neeg sawv cev VP -4 tuaj yeem ntxiv rau daim ntawv qhia zais cia los txhim kho qhov kev tswj hwm vulcanization, cov yam ntxwv zoo tshaj plaws, kub tsis kam, kev laus ua haujlwm, thiab shrinkage deformation ntawm EPDM roj hmab thiab cov khoom yas. Txo cov khoom lag luam ntawm EPDM roj hmab thiab cov khoom yas thiab txhim kho lub cev muaj zog ntawm cov khoom tiav thiab ua kom lub sijhawm siv.
