Cov nyhuv ntawm vulcanization ntawm cov qauv thiab cov khoom ntawm roj hmab

Cov nyhuv ntawm vulcanization ntawm cov qauv thiab khoom:

Hauv cov txheej txheem ntau lawm ntawm cov khoom siv roj hmab, volcanization yog kauj ruam dhau los. Hauv cov txheej txheem no, cov roj hmab nyob rau hauv cov txheej txheem sib xyaw ua ke, yog li tau txais cov roj hmab sib txuas thiab cov tshuaj tua hluav taws xob ua tau zoo ntxiv rau kev siv cov nqi thiab cov ntawv thov cov khoom lag luam.

Ua ntej Vulcanization: qauv qauv, kev sib txuam nrog kev sib txuam los ntawm cov van der waals yuam;

Cov Khoom: Zoo heev plasterity, siab elongation, thiab solubility;

Thaum lub sij hawm vulcanization: tus molecule pib pib, thiab cov tshuaj lom neeg sib txuas lus sib txuas tshwm sim;

Tom qab vulcanization: tus qauv network, muaj kev sib xyaw nrog kev sib tw tshuaj lom neeg;

Tus qauv:

(1) Kev Ua Phem;

(2) txoj hauj lwm ntawm kev sib txuas-txuas daim ntawv cog lus;

(3) Qib ntawm cross-sib txuas;

(4) hla kev sib txuas; Cov.

Khoom:

(1) cov khoom siv tshuab (tas li elongation lub zog. Hardness. Tensile muaj zog. Elongation. Elasticity);

(2) cov khoom siv lub cev

(3) Tshuaj Ruaj Ruaj Ruaj tom qab vertolanization;

Hloov pauv cov khoom ntawm roj hmab:

Noj cov roj hmab ntuj ua piv txwv, nrog kev nce ntawm vulcanization degree;

(1) hloov pauv cov khoom siv neeg (elasticity. Muab lub zog. Lub zog el

(2) Hloov pauv cov khoom siv lub cev, huab cua permeability thiab dej permeability txo, tsis tuaj yeem yaj, txhim kho kev kub, txhim kho kev kub ntxhov

(3) hloov pauv hauv tshuaj kom ruaj khov

Cov tshuaj muaj peev xwm nce, vim li cas

a. Cov kev sib tw hla kev sib txuas ua ke ua rau cov pab pawg ua haujlwm lossis cov atoms tsis muaj lawm, ua rau nws nyuaj rau kev laus tawm mus

b. Cov qauv network uas cuam tshuam ntawm cov qauv me me, ua rau nws nyuaj rau cov roj hmab radicals rau diffuse

Xaiv thiab Kev Txiav Txim Siab Roj Hmab Vulcanization

1. Vulcanization Siab

(1) xav tau siv thaum cov khoom siv roj hmab yog vulcanized. Lub hom phiaj yog:

a. Tiv thaiv cov roj hmab los ntawm tsim cov npuas thiab txhim kho cov roj hmab kev sib txuas;

b. Ua cov roj hmab cov khoom ntws thiab sau cov pwm kom ua cov khoom lag luam nrog cov qauv ntshiab

c. Txhim kho cov nplaum ntawm txhua txheej (txheej ntaub nplaum thiab daim ntaub txheej lossis ntaub txheej ntaub) hauv cov khoom lag luam, thiab txhim kho cov khoom siv lub cev (xws li cov tshuaj tsw qab (xws li vulcanizate.

(2) Feem ntau hais lus, kev xaiv ntawm vulcanization siab yuav tsum tau txiav txim siab raws li cov hom khoom, cov qauv, cov yees siv thiab lwm yam.

(3) Hauv txoj ntsiab cai, cov cai hauv qab no yuav tsum tau ua raws li: cov plastentity yog loj, lub siab yuav tsum me dua; Cov khoom tuab, tus naj npawb ntawm cov khaubncaws sab nraud povtseg, thiab cov qauv complex yuav tsum loj dua; Lub siab ntawm cov khoom lag luam nyias yuav tsum yog me dua, thiab txawm tias ib txwm muaj zog siv tau

Muaj ntau txoj hauv kev ntawm vulcanization thiab nias:

(1) Cov twj tso kua mis rau cov roj cua tshuab siab rau cov pwm los ntawm lub tiaj tus txiv ntoo kom huv, thiab tom qab ntawd hloov lub siab rau cov pwm

(2) ncaj qha nias los ntawm vulcanizing nruab nrab (xws li chav)

(3) nias cov pa los ntawm cov cua compressed

(4) txhaj tshuaj tiv thaiv tshuab

2. Vulcanization kub thiab kho lub sijhawm

Vulcanization kub yog qhov tseem ceeb tshaj plaws rau cov tshuaj tiv thaiv vulcanization. Lub vulcanization kub tuaj yeem cuam tshuam ncaj qha rau kev ua nrawm nrawm, cov khoom lag luam zoo thiab nyiaj txiag muaj txiaj ntsig ntawm kev lag luam. Vulcanization kub yog siab, lub pulcanization ceev yog nrawm, thiab kev ua haujlwm ntau dua; Txwv tsis pub, kev ua haujlwm ntau dua yog tsawg.

Nce vulcanization kub yuav ua rau muaj teeb meem hauv qab no;

(1) Ua rau cov kev tawg ntawm cov roj hmab molecular saw thiab vulcanization thim rov qab, ua rau muaj kev txo qis ntawm cov roj hmab sib txuas

(2) txo lub zog ntawm textiles hauv cov khoom lag luam roj hmab

(3) Lub sijhawm scorch ntawm cov roj hmab sib txuas yog luv, lub sijhawm puv, thiab cov khoom yog ib nrab ntawm cov kua nplaum.

(4) Vim tias cov khoom tuab yuav ua rau qhov sib txawv kub ntawm sab hauv thiab sab nraud ntawm cov khoom lag luam, ua rau tsis pom kev zoo nkauj
