accélérateur TMTD:
1. Ekoki kozwa esika ya TBZTD (Tetrabenzylthiuram disulfide), oyo ezali na bozangi ya bokengi ya makasi mpe ya bozongi nsima; TBZTD kombo ezali tetrabenzylthiuram disulfide, mokuse na TBZTD. Produit oyo ezali accélérateur ya thiram oyo esalemi sika, oyo ekoki ko remplacer TMTD (tetraméthyl disulfure thiram). Ekoki kosalelama lokola accélérateur ya caoutchouc ya vulcanisation ya mbangu to ya caoutchouc naturel, buté na yango ya caoutchouc to butératoire ya nature, buté naturel, rubber. The processing is safer and has a longer scorch time than TMTD. Due to its high molecular weight, high melting point and difficulty in decomposition, TBZTD does not produce nitrosamines. In particular, TBZTD only has a slightly lower vulcanization rate than TMTD. Other physical properties are almost the same as TMTD, and it has become a thiuram with great Potentiel ya développement. ya sika ya ba accélérateurs ya vulcanisation.
· Agent ya Vulcanisation DTDM:
1. DTDC (N, N'-dithiocaprolactam) can be used instead, which has a white crystal form, melting point of 120-122℃C, and active sulfur mass fraction greater than 0 19 . Replace the vulcanizing agent DTDM with the same amount without changing the formulation and process of the compound. Like the vulcanizing agent DTDM, the vulcanizing agent DTDC can replace sulfur in whole or in part to form an effective or semi-effective vulcanization system. Since the vulcanizing agent DTDC can release active sulfur under normal vulcanization conditions, and the added sulfur forms a monosulfide bond and a disulfide bond between the rubber molecules, the rubber vulcanization network structure can impart excellent heat resistance and compression resistance to the vulcanizate. Sex and high tensile Stress. Agent ya vulcanisation DTDC ezali mpe na bizaleli ya glaçage te, kozika ya coke ya sécurité mpe vitesse ya vulcanisation ya mbangu. Ezali agent ya vulcanisation ya malamu koleka mpo na biloko ya caoutchouc ya modèle ya monene lokola ba pneus, biloko ya caoutchouc oyo ekoki kozala na molunge te, biloko ya caoutchouc sanitaire mpe biloko ya caoutchouc ya couleur.
2. Disulfide d’alkylphénol (Vultac-5) ekoki kosalelama na esika ya disulfide ya alkylphénol, oyo ebongi mpo na kosalela na ba systèmes oyo ezali na ba polarités ndenge na ndenge mpe na ba murs ya mipanzi ya pembe.
3. Polysulfure oyo esalemi na mafuta ekoki kosalelama na esika na yango.
