Cov ntawv thov tseem ceeb ntawm cov tshuaj pim ntawm cov roj hmab kev lag luam suav nrog kev txhawb nqa cov roj hmab vulcanization, txhim kho cov khoom siv ntawm cov roj hmab, thiab lawv siv hauv cov roj hmab tshwj xeeb.
Txheej txheem vulcanization:
Peroxide vulcanizing cov neeg sawv cev yog ib hom organic compound muaj oo bonds, tsuas yog siv los txhawb txoj kev vulcanization txheej txheem ntawm roj hmab. Thaum rhuab, parsge decompose los tsim cov dawb radicals, uas hnov cov roj hmab molecules los ua cov roj hmab txuas nrog cov roj hmab thiab tshuaj tshwj xeeb
Txhim kho lub cev thiab tshuaj lom neeg:
Peroxide vulcanizing cov neeg sawv cev tuaj yeem txhim kho lub cev thiab tshuaj ntawm roj hmab. Roj hmab vulcanized nrog paintive muaj tus ntoo khaub ncaws sib txuas nrog cov kev sib tw ua kom muaj zog, kev nthuav dav zoo sib xws, cov tshuaj elastic sib raug zoo, thiab xim ruaj khov.
Ib qho ntxiv, peroxide vulcanized roj hmab tsis yog paug thiab tsis txau tias tsis dhau.
Daim ntawv thov hauv cov roj hmab tshwj xeeb:
Peroxide vulcanizing cov neeg sawv cev muaj ntau cov kev siv hauv ntau hom roj hmab:
1) Cov roj hmab tsis txaus ntseeg: xws li roj hmab ntuj (NR), BUTADILE roj hmab (BR), NBRRINE Butadiene Butadiene roj hmab (SBR), thiab lwm yam
2) cov roj hmab saturated: xws li ethylene roj hmab (EPM) thiab urdm), epdm tuaj yeem ua rau muaj kev vulcanized nrog ob qho tib si lossis leej faj
3) Vulcanization ntawm Lwm Yam Roj Hmab Roj Hmab, xws li Polyurethane Roj Hmab (Pur)
Hom ntau yam thiab lawv cov yam ntxwv:
Hauv cov roj hmab cov khoom lag luam, muaj ob hom feem ntau siv peroxide vulcanizing cov neeg sawv cev:
1) Peroxides uas muaj cov pab pawg carboxyl, xws li benzoyl peroxide (BPO), muaj qhov rhiab siab rau cov acids thiab tsawg decomposition kub
2) Peroxides tsis muaj pawg cab, xws li cov pab pawg carboxyl, xws li cov pab pawg carboxylwbeny peroxide (DCP), yog rhiab rau cov kua qaub thiab muaj lub siab hais daws qhov kub.
Teeb meem thiab cov kev daws teeb meem hauv cov ntawv thov siv:
Muaj qee qhov tsis zoo ntawm Peroxide Vulcanizing cov neeg sawv cev hauv cov ntawv thov kev ua kom qeeb, suav nrog qeeb zog ntawm lub cev, feem ntau cov pouldonization thiab tej zaum yuav muaj kev ntxhov siab nrog lwm tus neeg sawv cev.
Txhawm rau kom sib npaug kub tsis kam thiab lub cev thiab tshuab siv tshuab, portidides yog qee zaum siv hauv kev sib xyaw nrog Sulphur
Ib qho ntxiv, xaiv cov khoom ntxiv xws li tsis ua haujlwm yog (TPA) tuaj yeem ua kom muaj kev cuam tshuam nrog kev cuam tshuam nrog kev cuam tshuam nrog kev cuam tshuam nrog kev cuam tshuam nrog peroxide crosslinking kev phiv tshuaj.
