a. Kev faib tawm los ntawm kev noj cov leej faj: Qhov kev faib tawm thawj zaug tsom rau cov leej faj. Cov tshuab hluav taws xob sib txawv xav tau cov nqi sib txawv ntawm cov xaim hluav taws xob. Yog tias tsis muaj lub ntsuas nrawm siv txhua (tsuas yog cov leej faj thiab cov hlau oxides raug siv rau kev ntsuas tsis zoo), tom qab ntawd tus nqi ntawm leej faj tsim nyog kom ua tiav qhov tsawg kawg nkaus ntawm crosslinking yog qhov ntau tshaj plaws, uas hu ua" chav xoom" ;. Yog tias cov leej faj xav tau zoo ib yam li qhov no, cov ntsuas nrawm siv kuj tseem cais raws li" xoom qeb" ;. Qhov thib ob yog cov ntsuas nrawm tsuas yog xav tau me me ntawm cov leej faj; hom kawg tuaj yeem siv tau yam tsis muaj leej faj txhua, qhov ntawd yog, thiaj li hu ua leej faj pub los sis tus neeg sawv cev vulcanizing.
b. Kev faib tawm los ntawm cov pawg nquag: Txoj kev no tau faib raws li cov tshuaj lom neeg muaj txiaj ntsig zoo thiab cov pab pawg muaj txiaj ntsig hauv cov qauv ntawm ntau lub nrawm.
c. Kev faib tawm raws li kev ua kom vulcanization: uas yog, kev faib tawm raws li ceev ceev vulcanization, conventionally, nws tau cais raws li tus txheej txheem ntawm tus tsuj roj M (thiazole). Cov uas nws qhov chaw mos siv ceev tshaj li ntawm tus tsuj roj ceev ceev M tau faib ua qhov nrawm nrawm lossis nrawm nrawm dua; cov uas nws hais txog vulcanization nrawm qis dua li ntawm tus tsuj roj ceev M tau muab faib ua qhov nruab nrab ceev lossis nrawm nrawm nrawm.
d. Kev faib tawm los ntawm acidity thiab alkalinity
1. Acidic accelerator: tus tsuj roj uas yog acidic los sis cuam tshuam nrog tso cov hydrogen sulfide thaum lub caij vulcanization los tsim cov kua qaub. Thiazoles, thiurams thiab dithiocarbamates zwm rau pawg no
2. Alkaline accelerator: tus tsuj roj tias nws tus kheej yog alkaline lossis tuaj yeem hnov mob nrog hydrogen sulfide los tsim cov alkaline. Hauv pawg no yog guanidines, aldehyde amines thiab anilines
3. Qhov nruab nrab lub suab nrawm nrawm: cov ntsuas nrawm uas tsis nruab nrab lossis tuaj yeem tiv taus nrog hydrogen sulfide los tsim cov tshuaj acidic thiab alkaline tib lub sijhawm, xws li sulfenamides
