Ntxiv cov accelerators rau roj hmab tuaj yeem txhawb cov tshuaj tiv thaiv ntawm cov roj hmab thiab vulcanizer, ua kom cov vulcanization ceev, txo qhov kub ntawm vulcanization, txo lub sij hawm vulcanization, txo cov vulcanizer, thiab tib lub sij hawm txhim kho lub cev, txhua yam thiab tshuaj lom neeg ntawm vulcanized. roj hmab.
A. Cov roj hmab sib txawv siv cov tshuab vulcanization sib txawv thiab ntau hom accelerator.
B. Accelerators muaj kev txiav txim siab ntawm kev ua haujlwm scorch. Kev xaiv kom raug ntawm cov accelerators pab kev sib tov, calendering, extrusion thiab kev ruaj ntseg ntawm cov roj hmab. Feem ntau, molded vulcanization yuav tsum muaj qee lub sij hawm scorch, thaum moldless vulcanization tsis tas yuav ntev scorch lub sij hawm.
C. Lub scorch tsis kam ntawm lub accelerator muaj feem xyuam rau nws qhov kub thiab txias. Thaum lub ntsuas kub tseem ceeb tshaj, lub accelerator yog qhib kom sai. Thaum siv ntau lub accelerators nyob rau hauv kev sib xyaw ua ke, qee qhov accelerators yuav raug cuam tshuam, thiab qee qhov accelerators tseem yuav ua rau pom kev ua haujlwm ntau dua ntawm qhov kub thiab txias.
D. Kev sib xyaw ntawm cov accelerators yuav tsum ua kom cov roj hmab muaj qhov dav vulcanization flatness.
Roj Hmab yog ib qho khoom siv hluav taws xob tsis zoo ntawm cov cua sov, thiab qhov chaw thiab sab hauv ntawm cov roj hmab tsis rhuab tsis sib xws. Qhov dav vulcanization flatness yog qhov lav kom tsis txhob dhau-vulcanization thiab xyuas kom meej vulcanization ntawm txhua qhov ntawm cov khoom.
E. Kev sib txuam ntawm cov accelerators kuj tuaj yeem txhim kho cov khoom qub ntawm cov roj hmab vulcanized, muaj cov nyhuv plasticizing, thiab txhim kho cov khoom ua haujlwm ntawm cov roj hmab. Disadvantages: tsis zoo dispersibility thiab muaj kuab paug ntawm accelerators. Cov accelerators siv tam sim no feem ntau tsis muaj tshuaj lom.
