Qib ntawm vulcanization tuaj yeem tswj tau kom ua tiav cov khoom siv tshwj xeeb, ua rau nws muaj ntau yam txheej txheem rau ntau daim ntawv thov kev lag luam.

Cov tshuaj tiv thaiv muaj feem xyuam

Cov txheej txheem vulcanization feem ntau cuam tshuam nrog kev tsim cov sulfur cross-links ntawm cov roj hmab ntev polymer chains. Cov kev sib txuas sib txuas no yog tsim los ntawm cov tshuaj tiv thaiv kab mob, suav nrog ntxiv, hloov pauv, thiab tshem tawm cov tshuaj tiv thaiv. Lub xub ntiag ntawm cov accelerators thiab activators tuaj yeem ua kom cov tshuaj tiv thaiv no ua rau kom muaj txiaj ntsig ntau dua.

Hom Vulcanization

Muaj ntau ntau hom vulcanization txheej txheem, txhua qhov tsim nyog rau kev siv sib txawv:

• Pa Vulcanization: Siv cov sulfur thiab accelerators los tsim kom muaj kev sib npaug ntawm kev sib txuas.

• Peroxide Vulcanization: Siv cov organic peroxides rau cov ntawv thov uas yuav tsum tau ua kom sov siab.

• Radiation Vulcanization: Siv cov hluav taws xob hluav taws xob ntau los tsim cov kab sib txuas, feem ntau siv hauv kev kho mob thiab kev lag luam aerospace.

Keeb kwm ntsiab lus ntawm Vulcanization

Lub Discovery ntawm Vulcanization

Cov txheej txheem ntawm vulcanization tau tshawb pom los ntawm Charles Goodyear hauv xyoo 1839. Goodyear qhov kev tshawb pom tsis zoo tshwm sim thaum nws tso cov roj hmab thiab cov sulfur sib tov rau hauv qhov cub kub, ua rau cov khoom siv elastic thiab tiv taus qhov kub thiab txias. Qhov kev hloov pauv no tau hloov pauv kev lag luam roj hmab, tso lub hauv paus rau kev siv niaj hnub no.

Evolution ntawm Vulcanization Techniques

Tau ntau xyoo, cov txheej txheem vulcanization tau hloov kho kom tau raws li qhov xav tau ntawm ntau yam kev lag luam. Kev taw qhia ntawm cov accelerators nyob rau hauv lub xyoo pua 20th thaum ntxov tau txo cov sij hawm kho, thaum cov kev nce qib niaj hnub tau tsom mus rau eco-phooj ywg thiab siv tau zoo, xws li hluav taws xob thiab peroxide vulcanization.
