1. Makambo minei oyo osengeli kotalela ntango ozali kopona accélérateur .
1.1 Lolenge ya caoutchouc .
Caoutchouc différent ezali na ba propriétés différentes, système ya vulcanisation différents, système ya vulcanisation différents pona kopona ba types différents ya accélérateur, esengeli e considérer match entre bango.
1.2 Bolamu ya promoteur .
Qualité ya accélérateur ezali moko ya makambo ya ntina mpo na ingénieur ya formulation. na zando sikoyo, ezali kaka mingi na lokuta ya solo, phénomène oyo etondisi excellent na tango, esengeli kozala na bokebi tango ya kopona, soki te vulcanisation oyo ekozala na bopusi na caoutchouc directement to kopekisa bobange mpo na kozela respect.
1.3 Bopusi na bizaleli ya kosangisa mpe kosala vulcanisation ya caoutchouc .
Ba accélérateurs ezali na kati ya formation ya structure ya réseau spatial ya caoutchouc na tango ya vulcanisation, oyo ezali na relation directe na structure ya caoutchouc vulcanisé, ngai.E. ba propriétés physiques mpe mécaniques na yango mpe ba propriétés ya vieillissement. accélérateur ekoki ko douxir mélange, komatisaka plasticzation ya mélange, mpe ko changer propriété ya traitement ya{3}}
1.4 Bosali ya charring .
Accélérateur ezali na influence décisive na temps ya scorch (c'est-à-dire durée ya matériel ya caoutchouc avant ebandeli ya vulcanisation ya moto). Yango wana, accélérateur oyo oponi esengeli kosala que matériel ya caoutchouc ezala na temps ya kozika ya monene, oyo ezali na effet significatif na sécurité ya fonctionnement ya matériel ya caoutchouc na mélange, calendering} in recent years, in order to improve the production efficiency, the processing conditions are more and more strict, and the requirements for the anti-scorch performance of rubber materials are more and more high. However, too long scorch time will lead to the increase of the total curing time, which is not only not conducive to the improvement of labor efficiency, but also has an adverse effect on the deformation of mould-free vulcanization products in the vulcanization process.
The scorch resistance of accelerator is directly related to the critical temperature of vulcanization (that is , the temperature at which accelerator is not significant. At this temperature above the promoter activation, the full play of its vulcanization. Unfortunately, most accelerators have not yet been measured at this temperature. When multiple promoters are used together, some promoters are inhibited and some promoters show greater activity even below their critical temperatures.
