Kev lag luam nrawm
(1) Ua kom nrawm dua: dithiocarbamate thiab thiuram
(2) Kev nrawm nrawm: Thiazole thiab sulfenamide (sulfenamide qeeb raws li kev siv kinetics)
(3) qeeb qeeb: Guanidine
(4) Lwm yam nrawm: aldehyde amine, thiourea, cyclic dithiocarbamate
Sulfenamides tom qab thiazoles yog hom tseem ceeb tshaj plaws ntawm kev siv tshuab thiab kev lag luam. Yog tias amines yooj yim raug tsis quav ntsej (txhua tus amine muaj qhov cuam tshuam ntawm kev ua kom nrawm nrawm rau qee yam), cov tshuaj nrawm nrawm tuaj yeem sawv cev los ntawm cov qauv dav dav hauv qab no: X1=CX2X3 thiab X1=PX2X3X4, qhov twg cov pa roj carbon nruab nrab thiab phosphorus atom nyob ib puag ncig peb lossis plaub heteroatoms raws li nws qhov muaj txiaj ntsig, thiab heteroatom yuav yog SON. Rau lub nrawm nrawm, X1, X2, thiab X3 sawv cev rau ob qho tshuaj sulfur thiab ib qho nitrogen atom.
Cov keeb kwm ntawm sulfur vulcanization yog qhov xav tsis thoob thiab nthuav. Hauv ib puas xyoo dhau los thiab ib nrab, txawm hais tias tau ntxiv ntau yam thiab ua tau zoo hauv txoj hauv kev no, cov tshuaj sulfur vulcanization tseem tsis tau hloov pauv raws li txheej txheem txheej txheem. Coj mus rau hauv tus account qhov paub tsis zoo ntawm cov leej faj vulcanization, thiab nws txoj kev muaj sia nyob yog qhov tsim nyog ntawm kev saib xyuas. Cov kev tsis txaus ntseeg no suav nrog: tus neeg sawv cev vulcanizing txau los ntawm cov roj hmab nyoos lossis cov roj hmab vulcanized, muaj kuab paug thiab xim tsis zoo, tshwj xeeb tshaj yog cov laus tsis kam tiv taus cov pa oxygen thiab tsis muaj kab mob hauv lub cev, thiab cov txheej txheem tsis zoo thiab lub zog tensile ntawm qhov kub dua.
