Cawv ntawm vulcanization ntawm cov qauv thiab cov khoom ntawm roj hmab

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

Vulcanization yog ib kauj ruam tseem ceeb hauv kev tsim cov qauv roj hmab, uas yog cov txheej txheem kev hloov pauv ntawm lub cev, thiab cov khoom siv kub, txhim kho cov txiaj ntsig thiab cov khoom siv.

Cov qauv thiab cov khoom ntawm roj hmab tsis muaj kev hloov pauv tseem ceeb ua ntej thiab tom qab vulcanization. Cov roj hmab molecules ua ntej vulcanization muaj cov qauv kab ua yeeb yam ntawm lawv, nthuav qhia zoo heev yas thiab elongation, nrog rau solubility. Thaum lub sij hawm vulcanization, molecules yog triggered thiab yauv sib txuas lus sib txawv, tsim cov qauv network uas cov molecules tau sib raug zoo los ntawm kev sib raug zoo.

Cov qauv thiab cov khoom ntawm vulcanized roj hmab tsuas yog suav nrog:

Tus qauv: Kev sib koom ua noj, txoj haujlwm hla kev sib txuas lus, qib kev sib txuas ntawm kev sib txuas nrog, thiab hla kev sib txuas

Kev Ua Tau: Cov Khoom Siv Cov Neeg Khoyam (Lub Zog Siv Hluav Taws Xob

Tus txheej txheem vulcanization tuaj yeem hloov kho cov khoom ntawm roj hmab. Noj cov roj hmab ntuj ua piv txwv, raws li kev ua kom tiav ntawm vulcanization nce:

Hloov hauv cov khoom siv hauv cov neeg kho mob: nce ntxiv, lub zog tensile, thiab lub zog ua kom muaj zog, thiab tsis muaj zog zuj zus,

Hloov pauv cov khoom siv lub cev: Cov huab cua permeability thiab dej tsis zoo, tsis tuaj yeem rhuav tshem, cov pa hluav taws xob tau ua rau muaj cov pa hluav taws kub Lub network qauv uas cuam tshuam ntawm kev sib txawv ntawm cov lwg me me, ua rau nws nyuaj rau cov roj hmab dawb radicals rau diffuse.

Cov neeg ua kom huv, suav nrog cov siab, ntsuas kub, thiab lub sijhawm, yog cov ntsiab lus tseem ceeb uas txiav txim siab vulcanization cov txiaj ntsig. Qhov kev ua kom muaj kev lim hiam siab muaj qhov cuam tshuam tseem ceeb rau kev tsim cov npuas hauv cov khoom siv roj hmab, thiab sau cov pwm nrog cov khoom siv roj hmab nrog cov khoom siv roj hmab nrog cov khoom siv roj hmab nrog cov khoom siv roj hmab. Nws kuj tseem tuaj yeem txhim kho cov nplaum ntawm ntau txheej (roj hmab txheej thiab ntaub txheej txheej ntaub ntawv lossis txheej ntaub ntawm cov khoom siv lub cev ntawm cov roj hmab vulcanized (xws li buring tsis kam).

Lub pulcanization kub yog qhov yooj yim ntawm cov tshuaj tiv thaiv vulcanization, uas tuaj yeem cuam tshuam ncaj qha rau kev ua kom nrawm nrawm, khoom lag luam zoo ntawm kev lag luam. Tsa cov tshuaj tua hluav taws kub tuaj yeem nrawm nrawm nrawm nrawm, tab sis cov tshuaj tua hluav taws xob ntau ntxiv ntawm cov khoom siv roj hmab, thiab cov khoom siv roj hmab ntau ntxiv. Nws tseem tuaj yeem ua rau lub sijhawm ntsuas cov roj hmab, ua rau cov roj hmab tsis muaj zog thiab tsis sib xws ntawm cov khoom. Yog li no, kev xaiv ntawm vulcanization kub yuav tsum txiav txim siab txiav txim siab xws li hom roj hmab, vulcanization system, thiab cov qauv khoom.

Kev txiav txim siab vulcanization tej yam kev mob - suav nrog lub siab, ntsuas kub, thiab sijhawm - yog ib txoj kev nyuaj uas yuav tsum muaj ntawm ntau yam.

Vulcanization siab: Qhov kev xaiv ntawm vulcanization siab feem ntau yog nyob ntawm cov qauv tsim thiab xav tau cov khoom lag luam roj hmab. Feem ntau, kev xaiv ntawm siab yog feem ntau txiav txim siab los ntawm cov duab, qhov loj me, thiab cov khoom sib txawv ntawm cov khoom lag luam roj hmab. Qhov ntau dua lub siab, qhov zoo dua cov kua ntawm cov roj hmab, uas tuaj yeem sau cov pwm zoo dua. Nyob rau tib lub sijhawm, kev kub siab tuaj yeem tiv thaiv ntau tiam ntawm npuas thiab txhim kho lub compactness ntawm cov khoom. Txawm li cas los xij, ntau dhau los yuav ua rau ntws ntau dhau ntawm cov khoom roj hmab, ua rau cov qauv ntawm cov khoom lag luam.

Sulphurization kub: vulcanization kub ncaj qha cuam tshuam qhov nrawm thiab zoo ntawm cov tshuaj tiv thaiv volcanization. Qhov siab dua qhov ntsuas kub, sai sai sai ntawm cov tshuaj tiv thaiv vulcanization, tab sis nws yuav ua rau tawg ntawm cov khoom siv roj hmab molecular, cuam tshuam rau cov khoom siv lub cev ntawm cov khoom lag luam. Ib qho kev ua kom tsim nyog ua kom muaj qhov ntsuas qhov kub thiab txias tuaj yeem ua kom muaj cov tshuaj ntsuam zoo nkauj zoo tsis muaj kev puas tsuaj rau cov khoom siv roj hmab.

Sulfurization Lub Sij Hawm: Lub sijhawm vulcanization yog hais txog vulcanization kub. Cov sijhawm kub siab dua yuav kom muaj kev ua kom muaj kev ua kom muaj kev ua kom muaj tseeb luv luv lub sij hawm, thiab hloov ua lwm yam. Feem ntau, kev xaiv ntawm vulcanization lub sij hawm yuav tsum xav txog hom roj roj tais, vulcanization kub, thiab cov tuab ntawm cov khoom. Qhov kev ua kom zoo nkauj ntawm lub sijhawm txiav txim los ntawm kev sim tuaj yeem ua kom paub tseeb tias cov khoom siv roj hmab ua tiav cov cuab yeej siv tau zoo thiab kev laus.

Zuag qhia tag nrho, kev txiav txim siab lub vulcanization cov txheej txheem yog xav tau kev sim siab, nws yog feem ntau ua kom zoo dua cov khoom siv vulcanization kom tau txais cov khoom lag luam zoo tshaj plaws.
