Sulfur silane coupling agents (SCA-A69X thiab SCA-S75X) thiab mercapto silane coupling agents (SCA-S89M thiab SCA-S89E, thiab lwm yam) muaj cov kev hloov kho tseem ceeb heev rau cov xim dub, uas tuaj yeem txhim kho cov teebmeem thiab kev txhawb zog ntawm cov roj dawb thiab roj hmab. Lawv tuaj yeem txo qhov Mooney viscosity, thaum tshav kub kub thiab kev ywj siab thiab cov cuab yeej ua haujlwm ntawm cov khoom siv roj hmab, thiab ua kom hnav tsis zoo ntawm cov khoom siv roj hmab. Kev taw qhia ntawm silane coupling tus neeg ua hauj lwm ua rau daim ntawv thov ntawm cov roj carbon dawb hauv cov roj hmab kev lag luam ua ntej, tshwj xeeb tshaj yog nyob rau hauv "ntsuab" low rolling resistant tyres nrog tag nrho cov dawb carbon dub, lub luag hauj lwm ntawm silane coupling tus neeg saib xyuas yog txawm ntau zog thiab tsis txaus . Hauv radial log tsheb, silane coupling cov neeg ua hauj lwm kuj tseem ua tau zoo rau kev ua tiav ntawm qhov compound rau cov hlau hlau.
Ntxiv rau cov log tsheb, silane coupling cov neeg siv kuj siv nyob rau hauv qee lwm yam uas tsis yog carbon cov xim uas muaj cov xim roj hmab, xws li kev ua kis las, rubber rollers, thiab lwm yam, uas tseem ceeb rau kev txhim kho cov khoom hnyav ntawm cov khoom. Lwm yam roj hmab khoom xws li roj hmab hoses, tapes, roj hmab lwm yam khoom, thiab lwm yam., Tshwj xeeb tshaj yog qee cov pa roj carbon fillers muaj cov roj hmab khoom (xws li cov roj carbon dawb, kaolin thiab lwm tus).
Raws li lub hnab roj hmab vulcanization, cov roj hmab hnyuv taum hnyuv zaws feem ntau yog siv cov tshuaj sulfur silane coupling agent (SCA-A69X thiab SCA-S75X) thiab mercapto silane coupling agent (SCA-S89M thiab SCA-S89E, thiab lwm yam); Vinyl silanes (SCA-V71E thiab SCA-V71C) feem ntau yog pom zoo rau peroxide rubbers xws li roj hmab thiab EPDM roj hmab.
Txoj kev siv ntawm silane coupling agent tam sim no mas muaj xws li ib qho kev sib txuas ncaj qha thiab txoj kev ua ntej. Hauv kev sib xyaw ncaj nraim, tus neeg ua hauj lwm silane coupling, cov ntaub iav thiab cov roj hmab tsis sib xyaw (qhib los yog kneading) hauv ib qho piv txwv, thiab lwm yam ntxiv rau ntxiv. Yog li hais tias nws yuav tsis tiv thaiv cov neeg ua hauj lwm kaw lus silane los ntawm cov nplais ntawm cov khoom siv. Feem ntau cov neeg ua hauj lwm silane coupling yog ntxiv rau 1-2% ntawm cov compound. Qhov zoo dua ntawm qhov no yog tias qhov ntau npaum li cas yuav tsum tau kho, tus txheej txheem yog qhov yooj yim, tab sis cov dispersion effect tsis txaus siab heev.
Cov txheej txheem ua ntej yog ua ntej pretreat qhov deg ntawm inorganic filler nrog ib tug silane coupling tus neeg sawv cev los ntawm ib tug siab agitator, thiab ces sib tov hloov lub nplhaib hloov nrog roj hmab thiab lwm cov neeg ua haujlwm pabcuam. Feem ntau, tus neeg ua hauj lwm silane coupling yog ntxiv rau qhov nyiaj muab tub lim. 1 ~ 2%. Qhov zoo ntawm txoj kev yog tias qhov kev hloov kho yog ib qho zoo, thiab tus neeg tso npe ua ke rau silane coats tus thawj ntawm cov tub luam thawj zaug, thiab kev siv tau zoo tshaj plaws; tab sis nws yuav tsum tau ua hauj lwm ntxiv thiab khoom siv.
