Shenyang SunnyJoint Nga supplier of rubber additives, kimanyiddwa bulungi nti MBS/NOBs, TMTD, DTDM n’abalala promoters zijja kuvunda nitrosamine carcinogens mu biva mu intermediate eby’enkola ya vultcanization. otya okulonda ebirala? Njagala okukozesa enkola ya vulcanization eyamba obutonde bw’ensi okukola ku EU, laba wansi!
Vulcanization accelerators commonly used in tire production include sulfenamide accelerators and thiazole accelerators. The thiazole accelerator is non-toxic, but its scorch time is short, and the slow vulcanization rate determines that the production in the tire mainly occurs as a secondary accelerator, and the actual amount is small. The main applications are promoters M and DM.
Omulimu omujjuvu ogwa sulfenamide accelerators nga gulina obukuumi obulungi ogw’okulongoosa, sipiidi ya vulcanization ey’amangu n’ebintu eby’omubiri eby’amaanyi n’ebyuma bitwala ekifo ekisooka mu bikozesebwa mu kukola emipiira. ebitera okusannyalala mulimu MBS/NOBS, TBBS/NS, CBS/CZ, DCBS. /dz.
MBS produces nitrosamines, which have been discontinued by tire companies in developed countries and regions in the West. This product is still used in China. A small amount of thiuram accelerator is often added as a second accelerator in tire production. The commonly used product is tetramethylthiuram TMTD, which produces nitrosamines. A commonly used variety in sulfur Abagaba eddagala lino ye dithiodimorpholine DTDM, era ekola nitrosamines.
Ebintu ebisookerwako ebisatu ebiragiddwa waggulu bisobola okukola nitrosamines ez’obulabe eri omubiri gw’omuntu. Ebiragiro by’okutuuka ku bantu ebyalangirirwa omukago gwa Bulaaya biraga bulungi nti ebintu ebifulumizibwa mu EU bikugirwa okukozesa ebigimusa ebyo waggulu{1}} bino wammanga bye bimu ku bintu ebiwerako ebisaanira obutonde bw’ensi okusobola okujuliza:
1. TBBS/NS esobola okukozesebwa mu kifo ky'ekyo, naye ebisingawo Scorch Retarder CTP byetaaga okugattibwako;
2. TBSI esobola okukozesebwa mu kifo kya n-tert-bulyl-bis(2-benzothiazole) sulfenamide. eky’okwokya kiri wakati wa NOB ne DZ, era omuwendo mutono nnyo. erinnya ly’eddagala lya tbSi n-tert-butyl-bis({10}} benzothiatory accelerator, abbretated tbsi, abbretated tbsi, abbreator, abbretated tbsi sulfenamide accelerator. This product is used in the compound to extend the scorch time and slow down the vulcanization rate. Compared with TBBS, TBSI has a high molecular weight, good thermal stability, and a melting point higher than TBSS by more than 30℃C. It has the advantages of long scorch time and fast vulcanization speed. At present, TBSS etera okugabana ne Scorch Retarder CTP, era TBSI esobola okukozesebwa yokka mu kifo kya TBBS+CTP. Okugatta ku ekyo, TBSI nayo erina okutebenkera okunywevu kw’amazzi n’okutereka okwangu; Kiyinza okulongoosa ennyo obuziyiza bwa kapiira okutuuka ku kukendeeza ekibiriiti nga kifuula omupiira ogw’obutonde ogw’ekika kya vulcanis; Ekola bulungi mu bikozesebwa ebiyungiddwa mu kyuma kya kapiira; Kiyinza okukozesebwa mu elastomers zonna, naddala ku anti-reduction requirements. obuwanvu obw’amaanyi n’ebirungi ebirala.
3. It can be replaced by CBBS, and it will not produce an accelerator for N-nitrosamines. When it is replaced by NOBS in an equal amount, the vulcanization rate is completely equal. The scorch performance is slightly better than NOBS and CZ. The physical properties of vulcanizate are similar to those of NOBS, and are widely used in city tires and other rubber products.
4. XT580 esobola okukozesebwa mu kifo kya n-fatty benzothiazole sulfenamide, omulimu gwayo gwenkana ddala ne NOBs, tewali butwa, bbeeyi eri wansi okusinga NOBS.
