Accélérateur ya caoutchouc ezali kolobela accélérateur ya vulcanisation ya caoutchouc. vulcanisation ya caoutchouc esalemaka mingi mingi na nzela ya soufre, kasi réaction ya soufre na caoutchouc ezali malembe mingi, yango wana ba accélérateurs ya vulcanisation ebimi. addition ya accélérateur na molécule ya caoutchouc ekoki ko promouvoir activation ya vulkiner, kuna kuna na kati ya agent vulkinant, kuna kuna kuna na kati ya agent vulkinant, kuna ezali na yango kuna na agent vullinatateur, kuna kuna na kati ya agent vullinatant, kuna kuna ezali na yango na agent vullinateur, kuna kuna kuna na kati na yango ezali na agent vullinatérant, kuna kuna na kati ya agent vullinatateur, kuna kuna ezali na yango wana ezali na agent vullinatateur, kuna kuna kuna na kati na yango ezali na agent vullinatérant, kuna kuna ezali na yango na agent de vulkiner, kuna kuna kuna ezali na yango na agent vullinatateur, kuna kuna ezali kuna kuna achieving the effects of shortening the vulcanization time and lowering the vulcanization temperature. The main use of vulcanization accelerators are mainly sulfenamides, thiazoles, thiurams, and some terpenoids, thioureas and dithiocarbamates. Among them, sulfenamides have the best comprehensive performance and are the most widely used.
The rubber accelerator is an after-effect accelerator for natural rubber, butadiene rubber, isoprene rubber, styrene-butadiene rubber and reclaimed rubber. It is usually used in the manufacture of cables, tapes, rubber shoes, inner tubes, bright colors, etc., especially for alkalis. Strong carbon black rubber compound. It is safe at operating temperature, strong in scorch resistance, fast in vulcanization speed and high in tensile strength, which can increase the proportion of synthetic rubber used. Low toxicity and high efficiency, it is an ideal substitute for NOBS and has excellent comprehensive performance. It is called standard accelerator. Widely used in the production of radial tires. It can be used in combination with aldehyde amines, anthraquinones, and thiuram Ba accélérateurs. Tango esalelami elongo na retarder ya kozika PVI, esali système ya malamu ya vulcanisation. oyo esalelamaka mingi mingi na bokeli ya ba pneus, sapato ya caoutchouc, ba tuyaux, ba bandes mpe ba câbles.
The vulcanization mechanism of rubber is still mixed. This is because in the production of rubber products, there are insoluble natural rubber samples and a large number of simultaneous reactions, making it difficult to vulcanize rubber molecules into complex polymer networks. The mechanism can be roughly divided into two types: free radical mechanism and ion mechanism. Researchers such as Bacon and Famer et al. believe that the allylic resonance of the rubber makes it Facile ya ko remplacer hydrogène na groupe ya méthylène oyo ezali pembeni ya liaison double.
Na yango, na procédé ya vulcanisation ya caoutchouc, hydrogène double radical ya soufre oyo ezo scavenger hydrogène na groupe A-méthylène ya caoutchouc ezali ebandeli ya réaction. c’est-à-dire, processus ya réaction ezali processus ya radical libre. Bateman et al. ba ndimi que alimentation électrique ya procès double sur la rupture des causes, s'abonnez-vous les -s--sur-sis--s-iss- sys- sys--s Processus ya réaction ionique. Kino sikoyo, bolukiluki oyo ekoli mingi ezali mecanisme ya promotion ya vulcanisation ya mungwa ya zinc ya thiazole mpe dithiocarbamate ya zinc.
