Long vulcanization bilong raba, we inap long hariapim raba na vulkenaisesen ejen riaksen reit bilong ol samting, wantaim ol i kolim olsem vulcanization akselereta.Promoter i mekim wanpela bikpela wok tru long raba vulkenaisesen, putim liklik promota, i ken mekim gutpela taim bilong oraitim, sotim bilong kuring, inap long mekim gutpela wok bilong stretim, sotim taim bilong lukautim, sotim taim bilong lukautim, sotpela taim bilong oraitim sik, sotim taim bilong oraitim sik, sotim taim bilong lukautim, sotim taim bilong lukautim, sotim taim bilong lukautim, sotim taim bilong lukautim raba na vulcanization agent . dosage of curing agent, improve physical and mechanical properties of vulcanized rubber, such as improve the tensile strength, tensile modulus, hardness and abrasion resistance, improve the aging resistance of vulcanized rubber, can prevent spray frost, enlarge the using range of vulcanized rubber, can be made transparent and various colors of rubber products.Therefore, the promoter has been one of the essential raw materials in the raba indastri.
Accelerants can be divided into inorganic and organic materials.Inorganic accelerator since the discovery of more than a hundred years, but because of its low efficiency, vulcanized rubber performance is poor, in addition to a small amount of use in a few cases, the current has been replaced by organic accelerator, inorganic accelerator zinc oxide, magnesium oxide, calcium oxide, alkali kabonet na ol narapela samting nau ol i yusim moa yet olsem ogen akselereta ektiv ejen.
Bikos long bikpela wok bilong oganik akselereta, ol gutpela vulkenisasen mak, ol vulkenais raba fisikel na mekanik samting na ol samting bilong mekim wok i go lapun, olsem na dispela kain akselereta i bin kamap hariap.}Long nau, i gat moa long 100 kain komoditi, tasol 50 o 60 kain tasol ol i save yusim. tasol.
Folem kemikol strakja ia, oli save divaedem i go long: dithiokarbamate, xantet, thiolane, thiazole, thiazole, salfonamid, aldos amine, guanidine, thiourea, amine mo ol narafala samting olsem long.…”
Bikos long ol kain kain raba, wankain akselereta i no inap long promotim vulkenisasen bilong ol narapela raba.Long netsurel raba na planti jeneral sintetik raba (olsem butyl bensin raba, tasolil butil raba, isopentil raba), jenerali bilong superakselereta dithiofenil formateofmeit, xantheyerta type accelator dithiofenyal formateofmeit, xanthy taep acceleta dithiophenyl formateofmeit, xanthy type accelator dithiofenyl formateefmet . akselereta thiazole, salfonamides na hap bilong aldos amine akselereta;Mdium spit akselereta i gat ol taiourea, guanidine na sampela aldosis ami akselereta;Ol wik promota em ol amines na sampela aldehaid na amines{1}}
Na tu bihainim akselereta na haidrojen salfaid riaksen bilong asid, alkaline o niutral, na akselereta i bruk i go long asid akselereta, alkaline akselereta na neutral akselereta.
Ol dispela samting i mas tingim taim ol i makim ol promota long makim stretpela kain promota bilong ol narapela raba samting.
