Not the application of dissolve sex brimstone in balata

Not dissolve sex brimstone mixes refine process in balata in with Sha Jing in sizing material of balata of formal consist in, can avoid frost of sizing material gush, prevent brimstone migratory, make sizing material keeps better shape agglutinant. Not dissolve sex brimstone is not stable, in temperature of sizing material vulcanization high in that way temperature falls can reductive for common brimstone, the vulcanization that finish. So, the application in tire and goods is expanding. Current, the national standard that the newspaper approves " balata compounding ingredient -- brimstone -- experiment method " equivalent uses international level, have " heat is returned former " test method, determine not dissolve sex brimstone is in the stability of 105 ℃ , its are in token the stability during mixing refine. Because not dissolve sex brimstone is metastable decides position, will happen in 100~130 ℃ return former, translate into is common brimstone. So, auxiliary factory should increase its thermal stability as far as possible, the temperature mixing refine of rubber factory should as far as possible low, during assuring to mix refine not dissolve sex brimstone not translate into is common brimstone, not gush frost, make sure sequel shapes successful.

At present product of limited company of chemical industry of sea of Beijing of domestic above sea most seriation, have high fever stability, tall not content of dissolve sex brimstone and tall dispersive sex (abbreviation 3 tall) breed. Flourish becomes the unit such as total factory of city chemical industry in succession put into production high fever stability not ISHS8010 of product of series of dissolve sex brimstone, ISHS7510, ISHS7020 and ISHS6033. Additional, during keep in storage, the amine below any temperature and experience of other and alkalescent gas are brought about not translate into of dissolve sex brimstone is common brimstone, so, do not will not dissolve sex brimstone deposits the product that releasing free amine (as follows sulphonic acid amide kind accelerant and vulcanizing agent DT, near DM) . Not of dissolve sex brimstone change (or heat is returned former) can bring about not frost of vulcanization glue gush.
