Daim ntawv thov
1.Huva-2, raws li cov roj hmab pub ntau zog ntxiv, tuaj yeem siv ua ob qho tib si vulcanizing tus neeg sawv cev rau cov khoom siv roj hmab peroxide thaum roj hmab ua. Nws kuj tseem tuaj yeem siv los ua tus neeg saib xyuas hluav taws xob tiv thaiv thiab cov neeg sawv cev tuab, haum rau ob qho kev siv roj hmab thiab roj hmab tshwj xeeb thiab roj hmab.
2. Siv roj hmab ntuj ntuj, hva - 2, thaum sib xyaw ua ke, txhim kho cov adhesion ntawm cov roj hmab thiab nce modulus ntawm cov roj hmab vulcanized. HVA-2 yog siv nyob rau hauv cov roj hmab xws li txheej txheem roj hmab thiab ntas txheej rau kev thauj cov log tsheb, uas tuaj yeem daws qhov teeb meem ntawm lub xub pwg ntawm cov kab pheeb lub log tsheb. Nws kuj tseem siv tau rau loj-qhov loj loj cov khoom lag luam ntawm ntuj roj hmab thiab ntau cov roj hmab lwm yam khoom.
3.hva - 2 tuaj yeem siv los ua cov roj hmab vulcanization roj hmab, stominated butyl roj hmab, Acryone roj hmab, thiab roj hmab sib xyaw. Nws tuaj yeem txhim kho qhov kev sib txuam sib cuam tshuam, txhim kho tshav kub tiv taus, thiab yog qhov tsim nyog rau cov tshuab kub siab. Nws tuaj yeem cuam tshuam ntau dua qub, txo cov khoom siv roj hmab thaum ua, thiab txhim kho cov khoom siv roj hmab thaum cov khoom siv roj hmab, kab kab sib xws, thiab cov hlau kab hlau.
4.hva - 2 yog sulfur dawb vulcanizing tus neeg sawv cev siv rau cable roj hmab. Nws tuaj yeem hloov tag nrho cov leej faj -}} muaj cov khoom siv ntawm tooj liab thiab thiurams, daws cov khoom siv ntawm tooj liab thiab thiuram
