Kev cuam tshuam ntawm vulcanization ntawm cov qauv thiab cov khoom ntawm cov roj hmab

Qhov cuam tshuam ntawm vulcanization ntawm cov qauv thiab cov khoom ntawm cov roj hmab:

Vulcanization yog ib kauj ruam tseem ceeb hauv kev tsim cov khoom siv roj hmab, uas yog cov txheej txheem ntawm kev hloov ntawm cov qauv linear mus rau lub cev qauv, coj cov kev hloov pauv xws li lub cev thiab cov khoom siv, qhov kub thiab txias, hnyav tsis kam, thiab corrosion kuj, txhim kho tus nqi thiab daim ntawv thov. ntau yam ntawm cov khoom.

Cov qauv thiab cov khoom ntawm cov roj hmab tau hloov pauv tseem ceeb ua ntej thiab tom qab vulcanization.Cov roj hmab molecules ua ntej vulcanization muaj cov qauv linear nrog van der Waals rog ua haujlwm ntawm lawv, nthuav tawm cov yas zoo thiab elongation, nrog rau solubility.Thaum lub sij hawm vulcanization txheej txheem, molecules yog triggered thiab undergo chemical cross-linking reactions, tsim ib tug network qauv uas molecules yog bonded los ntawm tshuaj bonds.

Cov qauv thiab cov khoom ntawm vulcanized roj hmab feem ntau suav nrog:

Structure: chemical bonds, txoj hauj lwm ntawm cross-linking bonds, degree ntawm cross-linking, thiab cross-linking

Kev ua tau zoo: Cov khoom siv kho tshuab (lub zog tsis tu ncua elongation, hardness, tensile zog, elongation, elasticity), lub cev muaj zog, tshuaj stability tom qab vulcanization

Cov txheej txheem vulcanization tuaj yeem hloov kho cov khoom ntawm cov roj hmab.Noj cov roj hmab ntuj ua piv txwv, raws li qib ntawm vulcanization nce:

Kev hloov pauv hauv cov khoom siv kho tshuab: nce elasticity, tensile zog, tensile lub zog, tsim kua muag lub zog, thiab hardness, txo elongation, compression mus tas li deformation, thiab qaug zog tshav kub tiam

Kev hloov pauv ntawm lub cev muaj zog: Cov huab cua permeability thiab dej permeability txo qis, tsis tuaj yeem yaj, tuaj yeem o tuaj yeem ua kom sov, tiv thaiv kev kub ntxhov, tshuaj lom neeg ruaj khov txhim kho, cov tshuaj tiv thaiv crosslinking tshem tawm cov pab pawg ntau lossis cov atoms, ua rau cov tshuaj tiv thaiv kev laus tsis yooj yim.Cov qauv network cuam tshuam qhov diffusion ntawm cov molecules tsawg, ua rau nws nyuaj rau cov roj hmab dawb radicals kom diffuse.

Lub vulcanization tej yam kev mob, nrog rau lub siab, kub, thiab lub sij hawm, yog lub ntsiab yam tseem ceeb uas txiav txim lub vulcanization tshwm sim.Lub siab vulcanization muaj qhov cuam tshuam tseem ceeb ntawm kev tiv thaiv kev tsim cov npuas hauv cov khoom siv roj hmab, txhim kho cov khoom siv roj hmab, thiab sau cov pwm nrog cov khoom siv roj hmab.Nws kuj tseem tuaj yeem txhim kho qhov adhesion ntawm ntau cov khaubncaws sab nraud povtseg (cov roj hmab txheej thiab txheej ntaub lossis hlau txheej, txheej ntaub thiab ntaub txheej) hauv cov khoom, thiab txhim kho lub cev ntawm cov roj hmab vulcanized (xws li khoov tsis kam).

Qhov kub ntawm vulcanization yog qhov tseem ceeb ntawm cov tshuaj tiv thaiv vulcanization, uas tuaj yeem cuam tshuam ncaj qha rau vulcanization ceev, cov khoom zoo, thiab cov txiaj ntsig kev lag luam.Kev nce lub vulcanization kub tuaj yeem ua kom lub vulcanization ceev thiab txhim kho kev tsim khoom, tab sis ntau dhau vulcanization kub tuaj yeem ua rau muaj teeb meem xws li roj hmab molecular saw breakage, vulcanization thim rov qab, txo cov khoom siv roj hmab, thiab txo lub zog ntawm textiles.Nws tseem tuaj yeem ua rau luv luv lub sijhawm scorching ntawm cov khoom siv roj hmab, ua rau cov roj hmab hauv zos tsis muaj zog thiab tsis sib xws ntawm cov khoom siv vulcanization.Yog li ntawd, kev xaiv ntawm vulcanization kub yuav tsum ua tib zoo xav txog yam xws li roj hmab hom, vulcanization system, thiab cov qauv khoom.

Kev txiav txim siab vulcanization tej yam kev mob - nrog rau lub siab, kub, thiab lub sij hawm - yog ib tug complex txheej txheem uas yuav tsum tau xav txog ntau yam.

Vulcanization siab: Kev xaiv ntawm vulcanization siab feem ntau yog nyob ntawm tus qauv tsim thiab cov khoom siv roj hmab.Feem ntau, kev xaiv lub siab yog txiav txim siab los ntawm cov duab, qhov loj me, thiab qhov nyuaj ntawm cov khoom siv roj hmab.Qhov siab dua, qhov zoo dua qhov fluidity ntawm cov roj hmab, uas tuaj yeem ua rau pwm zoo dua.Nyob rau tib lub sijhawm, kev kub siab tuaj yeem tiv thaiv kev tsim cov npuas thiab txhim kho cov compactness ntawm cov khoom.Txawm li cas los xij, kev siv zog ntau dhau tuaj yeem ua rau cov khoom siv roj hmab ntau dhau, ua rau muaj kev cuam tshuam ntawm cov khoom.

Sulfurization kub: Lub vulcanization kub ncaj qha cuam tshuam qhov ceev thiab zoo ntawm vulcanization cov tshuaj tiv thaiv.Qhov siab dua qhov kub, qhov ceev ntawm vulcanization cov tshuaj tiv thaiv, tab sis nws yuav ua rau cov roj hmab molecular chains tawg, cuam tshuam rau lub cev ntawm cov khoom.Qhov kub vulcanization uas tsim nyog tuaj yeem ua kom muaj qhov zoo vulcanization ceev yam tsis ua rau muaj kev puas tsuaj loj rau cov khoom siv roj hmab.

Lub sij hawm sulfurization: Lub sij hawm vulcanization yog ncaj qha ntsig txog qhov kub ntawm vulcanization.Qhov kub siab dua tuaj yeem xav tau lub sijhawm luv vulcanization, thiab rov ua dua.Feem ntau, kev xaiv vulcanization lub sij hawm yuav tsum xav txog cov khoom siv roj hmab, vulcanization kub, thiab thickness ntawm cov khoom.Lub sijhawm zoo vulcanization txiav txim siab los ntawm kev sim tuaj yeem ua kom cov khoom siv roj hmab ua tiav cov khoom siv kho kom zoo thiab kev laus ua haujlwm.

Zuag qhia tag nrho, kev txiav txim siab ntawm vulcanization tej yam kev mob yog ib tug txheej txheem uas yuav tsum tau kev saib xyuas ntawm ntau yam xws li hom roj hmab cov khoom, cov khoom zoo li, vulcanization khoom, thiab lwm yam. Nyob rau hauv tiag tiag ntau lawm, nws yog feem ntau yuav tsum tau ua ntau yam kev sim thiab maj optimize lub vulcanization tej yam kev mob. kom tau txais cov khoom lag luam zoo tshaj plaws.
