In the vulcanization of rubber, where can accelerate the rubber and vulcanization agent reaction rate of the material, collectively referred to as vulcanization accelerator.Promoter plays a very important role in rubber vulcanization, add a small amount of promoter, can greatly accelerate the reaction between rubber and vulcanizing agent, improve the curing speed, shorten the curing temperature, curing time, reduce the 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 rubber industry.
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efficiency, vulcanized rubber performance is poor, in addition to a small amount of use in a few cases, the current has been replaced by organic accelerator, inorganic accelerator zinc oxide, magnesium oxide, calcium oxide, alkali carbonate and so on are now mostly used as organic Agent akola accelerator.
Olw’obulungi obw’amaanyi obw’ekirungo ekiziyiza obutonde, engeri ennungi ey’okufuula enseenene, eby’obutonde eby’omubiri n’okukaddiwa ebifuusiddwa mu kapiira, bwe kityo ekika kino eky’okusannyalala ne kikolebwa mu bwangu.Mu kiseera kino, waliwo ebika by’ebintu ebisukka mu 100, naye ebika 50 oba 60 byokka bye bikozesebwa ennyo ..
Okusinziira ku nsengekera y’eddagala, esobola okwawulwamu: dithiocarbamate, xanthate, thiolane, thiazole, sulfonamide, aldose amine, guanidine, thiourea, amine n’ebirala .okusinziira ku ddaala ly’okutumbula effect, abakulembeze bayinza okugabanyizibwamu: super promoters, medium super promotions, medium speed permosts, medium speed permosr
Because of the different types of rubber, the same accelerator can not promote the vulcanization of different rubber.For natural rubber and most general synthetic rubber (such as butyl benzene rubber, butyl butyl rubber, isopentyl rubber), generally belong to the superaccelerator dithiophenyl formate, xanthate and thiuram type accelerator;Belong to the Chinese super accelerator thiazole, sulfonamides and part of the Aldose amine accelerator;Ebyuma ebikuba sipiidi ebya wakati mulimu thiourea, guanidine ne aldose amine accelerators;ebitumbula ebinafu bye bino amine ne aldehydes ezimu ne amine.
Era okusinziira ku nkola ya accelerator ne hydrogen sulfide eya asidi, alkaline oba neutral, era accelerator egabanyizibwamu asidi accelerator, alkaline accelerator ne neutral accelerator.
Ensonga zino wammanga zirina okulowoozebwako nga olondawo promoters okulonda ekika kya promoters ekituufu ku bintu eby’enjawulo ebya kapiira.
Sipiidi y'okuwonya.
Ebika bya kapiira eby’enjawulo nga biriko enkola ey’enjawulo ey’okufuula enseenene, omuli n’ekika ky’okulonda eky’okusannyalala n’okukwatagana.
(3) Coke Burning Performance Promoter Ku Coke Burning Time of the Material ekola omulimu ogw’okusalawo, kale okulonda kulina okukakasa nti ekintu ekiri mu kukola kwa bulijjo (okutabula, okuyiringisibwa, okunyiga) tekijja kuba nga tekinnatuuka vulcanized.
(4) Vulcanized rubber resistance okudda ku original Kino kikulu nnyo naddala mu bintu eby’olubereberye, olw’obutambuzi bw’ebbugumu obutali bulungi bwa kapiira, ebitundu ebyokya birina okulonda okuziyiza okulungi okudda ku kiwujjo kya kapiira ekyasooka, okusobola okwewala kapiira mu nkola y’okukendeeza ku vulcanization phenomenon.
(5) Vulcanized rubber performance selection accelerator, nga kwotadde okukakasa okukola kwa kapiira, naye era okufaayo okutuukiriza ebyetaago by’omutindo gw’ebintu, esobola okutereezebwa enkola ya Vulcanized okulongoosa eby’omubiri n’ebyuma eby’obuziyiza bwa vulcanized n’okukaddiwa.
Ng’oggyeeko ensonga ezo waggulu, era erina okulowooza ku kiwujjo kya kapiira mu kusaasaana kwa kapiira, obucaafu, langi, obutwa n’ebintu ebirala ebikwasaganya.
