Txhawm rau txhim kho kev ua haujlwm ntawm cov khoom siv roj hmab

Hauv kev tsim khoom, cov txheej txheem ua haujlwm yuav tsum tau nqa tawm rau cov roj hmab nyoos. Raws li qee qhov xwm txheej, cov roj hmab nyoos hauv cov roj hmab yuav hnov ​​​​mob nrog cov vulcanizing tus neeg sawv cev ua kom nws sib txuas los ntawm cov kab macromolecules mus rau peb-dimensional network macromolecules, kom cov roj hmab muaj cov khoom zoo xws li lub zog siab, siab elasticity, siab hnav tsis kam. , corrosion kuj thiab lwm yam. Cov txheej txheem no hu ua roj hmab vulcanization. Feem ntau, cov txheej txheem vulcanization tau muab faib ua plaub theem: induction - pre sulfur - zoo vulcanization - persulfation. Txhawm rau kom paub cov tshuaj tiv thaiv no, lub zog yuav tsum tau ntxiv kom nws ncav cuag qhov kub ntawm vulcanization, thiab tom qab ntawd cov roj hmab yog insulated kom tiav tag nrho cov vulcanization tshwm sim nyob rau hauv qhov kub ntawm vulcanization no.
