Koj paub ntau npaum li cas txog cov txheej txheem vulcanization?
Vulcanization yog txheej txheem kawg hauv kev ua cov roj hmab, uas tuaj yeem tau txais cov khoom siv roj hmab zaum kawg nrog tus nqi tsim nyog.
Kev ua haujlwm ntawm vulcanization yog ua kom cov roj hmab molecules tau txais kev sib txuas ntawm cov tshuaj tiv thaiv, hloov cov qauv linear qub rau hauv cov qauv network, txhim kho kev ua tau zoo, thiab hloov cov yas lub cev rau hauv elastomer nrog cov nqi siv tau.
Hauv kev tsim cov roj hmab hoses, vulcanization yog txheej txheem tseem ceeb kom ua tiav lub zog sib txuas siab ntawm cov roj hmab thiab cov txheej txheej, ua rau nws tag nrho. Nws kuj yog ib qho tseem ceeb txuas los xyuas kom meej cov khoom zoo.
Tom qab vulcanization, lub cev thiab txhua yam khoom ntawm cov roj hmab xws li lub zog, elasticity, tensile modulus, thiab lwm yam yuav zoo dua, cov yas deformation yuav raug txo, thiab nws yuav dhau los ua ib qho elastomer insoluble.
Cov txheej txheem ua ntej vulcanization, xws li plasticizing, mixing, calendering, thiab lwm yam, yog tag nrho cov kev npaj rau vulcanization, thiab vulcanization yog qhov txuas tseem ceeb rau kev ua tiav.
Vulcanizationyog qhov txuas tseem ceeb hauv kev tsim cov khoom siv roj hmab, feem ntau yog vim li cas hauv qab no
Cov txheej txheem vulcanization muab cov khoom siv roj hmab rau lub cev thiab cov khoom siv kho tshuab.
- Los ntawm vulcanization, ib qho kev sib txuas sib txuas tshwm sim ntawm cov roj hmab molecules los tsim cov qauv kev sib txuas ntawm peb sab, uas hloov cov roj hmab los ntawm lub xeev yas mus rau lub xeev elastic heev thiab tau txais qhov xav tau hardness, tensile zog, hnav tsis kam thiab lwm yam khoom.
- Kev tswj ntawm cov txheej txheem vulcanization tsis ncaj qha cuam tshuam rau kev ua tau zoo ntawm cov khoom siv roj hmab.
- Kev hloov ntawm vulcanization kub, lub sij hawm, vulcanizing tus neeg saib xyuas ntau npaum li cas thiab lwm yam tsis yuav muaj kev txiav txim siab ntawm hardness, tensile lub zog, aging kuj thiab lwm yam khoom ntawm cov khoom siv roj hmab. Vulcanization yog qhov txuas tseem ceeb hauv kev muab cov khoom siv roj hmab rau cov khoom tsim nyog, uas ncaj qha txiav txim siab qhov zoo ntawm cov khoom.
- Lwm cov txheej txheem xws li mastication thiab sib tov yog tag nrho cov kev npaj rau vulcanization, thiab vulcanization yog lub hauv paus ntawm kev ua tau zoo.
- Kev ua tsis zoo vulcanization tuaj yeem ua rau muaj qhov tsis xws li npuas thiab kev sib txuas tsis zoo hauv cov khoom siv roj hmab.
- Cov npuas yuav cuam tshuam rau cov khoom tseem ceeb xws li kev sib khi thiab hnav tsis kam ntawm cov khoom siv roj hmab, yog li kev tswj hwm ntawm cov txheej txheem vulcanization tseem ceeb tshwj xeeb.
- Vulcanization yog cov txheej txheem tseem ceeb los ua cov roj hmab thiab cov txheej txheem ntxiv rau tag nrho
- Rau cov khoom siv roj hmab ntxiv, vulcanization tuaj yeem txhim kho lub zog sib txuas ntawm cov roj hmab thiab cov txheej txheem ntxiv kom ntseeg tau tias kev ua haujlwm tag nrho.
Hauv cov ntsiab lus, cov txheej txheem vulcanization muab cov khoom siv roj hmab cov khoom tsim nyog, tswj cov khoom zoo, thiab cuam tshuam rau kev ncaj ncees ntawm cov roj hmab thiab cov txheej txheem ntxiv. Nws yog qhov txuas tseem ceeb tshaj plaws hauv kev tsim cov khoom siv roj hmab.
