Vulcanization system rau roj hmab foob
Cov roj hmab vulcanization system yog ib feem tseem ceeb ntawm cov roj hmab kev lag luam, uas hloov cov roj hmab los ntawm ib tug mos mos thiab viscous thawj lub xeev mus rau cov khoom siv roj hmab nrog cov yam ntxwv zoo xws li elasticity thiab hnav tsis kam los ntawm kev pib sib txuas cov tshuaj tiv thaiv ntawm cov roj hmab molecular chains. Kev xaiv thiab tsim ntawm vulcanization system ncaj qha cuam tshuam rau kev ua haujlwm, kev pabcuam lub neej, thiab kev tsim khoom ntawm cov khoom siv roj hmab. Kab lus no yuav qhia txog cov yam ntxwv, cov qib roj hmab siv tau, thiab daim ntawv thov ntawm txhua qhov vulcanization system kom ntxaws, los pab cov neeg nyeem kom nkag siab zoo txog cov txheej txheem thiab xaiv cov khoom siv roj hmab.
Tsob nroj sulfur vulcanization system
Nta: Cov tshuaj sulfur vulcanization system yog cov qub thiab feem ntau siv roj hmab vulcanization txoj kev. Nws ua rau cov roj hmab muaj zog elasticity thiab tensile lub zog los ntawm kev ntxiv cov sulfur, uas reacts chemically nrog roj hmab molecules ntawm qhov kub thiab txias los tsim cross-linked bonds. Tus nqi ntawm leej faj ntxiv feem ntau yog 1.5-3.0 qhov chaw ntawm 100 qhov chaw roj hmab (PHR), thiab qhov kub ntawm vulcanization feem ntau tswj ntawm 140-160 degree .
Siv tau hom roj hmabCov roj hmab ntuj (NR), styrene-butadiene roj hmab (SBR), butadiene roj hmab (BR), thiab nitrile roj hmab (NBR).
Daim ntawv thov: Vim hais tias cov tshuaj sulfur vulcanization system tuaj yeem txhim kho lub cev zoo ntawm cov roj hmab, tshwj xeeb tshaj yog kev puas tsuaj, qaug zog, thiab elasticity, nws yog dav siv nyob rau hauv kev tsim ntawm ntau yam log tsheb, khau khau, conveyor siv, shock absorbing qhov chaw, thiab lwm yam. cov khoom. Nyob rau hauv rooj plaub ntawm cov log tsheb, kwv yees li 300 lab lub log tsheb tau tsim tawm thoob ntiaj teb txhua xyoo uas siv cov tshuaj sulfur curing systems.
Qhov zoo: Cov tsoos vulcanization system muaj qhov zoo ntawm kev ua haujlwm yooj yim thiab tus nqi qis, thiab tsim nyog rau kev lag luam loj loj. Nyob rau tib lub sijhawm, nws tuaj yeem muab lub neej ua haujlwm ntev thiab lub cev zoo rau cov khoom. Yog li ntawd, txawm hais tias muaj ntau yam tshiab vulcanization tshuab tau tshwm sim, cov tsoos sulfur vulcanization system tseem tuav txoj haujlwm tseem ceeb hauv kev lag luam roj hmab.
Peroxide vulcanization system
Nta: Lub kaw lus peroxide vulcanization yog ua kom muaj kev sib txuas ntawm cov roj hmab los ntawm kev ntxiv peroxide (xws li cumene peroxide DCP) ua tus neeg sawv cev vulcanizing. Cov txheej txheem no tsis tas yuav muaj kev koom tes ntawm leej faj thiab feem ntau kho tau ntawm 160-180 degree, ua rau nws tsim nyog rau cov khoom siv roj hmab tshwj xeeb uas yuav tsum tau muaj qhov kub thiab txias vulcanization. Peroxide vulcanization tuaj yeem txhim kho cov cua sov, roj, thiab kev laus ntawm cov roj hmab.
Siv tau hom roj hmab: Ethylene propylene roj hmab (EPDM), silicone roj hmab (Si), fluorine roj hmab (FKM), neoprene roj hmab (CR), thiab polyolefin roj hmab.
Daim ntawv thov teb: Peroxide vulcanization system feem ntau yog siv rau hauv cov khoom siv roj hmab nrog cov kev xav tau siab rau kev kub siab thiab tshuaj tiv thaiv corrosion. Piv txwv li, qhov no vulcanization system feem ntau yog siv rau hauv cable tsho, ntsaws ruaj ruaj, thiab roj- thiab kub-resistant qhov chaw nyob rau hauv automotive engines. Hauv particular, ethylene propylene diene monomer (EPDM), muaj huab cua zoo heev thiab kub tsis kam, thiab li ntawm 30% ntawm EPDM roj hmab noj thoob ntiaj teb txhua xyoo yog tsim los ntawm peroxide vulcanization.
Qhov zoo: Piv nrog cov tshuaj sulfur vulcanization system, peroxide vulcanized cov khoom muaj kev laus tiv thaiv zoo dua thiab tuaj yeem tswj kev ua haujlwm ruaj khov nyob rau lub sijhawm ntev kub lossis muaj zog corrosive ib puag ncig. Qhov no ua rau cov tshuab peroxide vulcanization yog ib txoj haujlwm tseem ceeb hauv kev lag luam aerospace, tsheb, thiab high-end manufacturing industries.
