MBS/BS, TMTD, DTDM Reference Ebirala - Kola ku EU

Nga bwe kimanyiddwa bonna, MBS/BS, TMTD, DTDM ne promoters endala zijja kuvundira ebirungo ebitta kkansa bya nitrosamine mu biva mu bitundu eby’omu makkati eby’enkola ya sulfide. olonze bikyusakyusa?Oyagala okwettanira enkola y’okukuuma obutonde bw’ensi okukola ku mukago gwa Bulaaya, laba wansi!
 
Ebitumbula eby’obuwuka obuyitibwa vulcanization promoters mu kukola emipiira ye sulfonamide promoters ne thiazole promoters.Thiazole promoters tezirina butwa, naye eby’okulabirako by’obudde obw’okwokya obumpi n’obwangu bw’okugenda mpola mu nvubu zisalawo nti zisinga kukozesebwa nga ebitumbula ebiyamba mu kukola emipiira, nga waliwo okukozesa okutono ddala. enkozesa enkulu ze zisinga okutambuza M ne DM{ dm. enkozesa entuufu. enkozesa enkulu ze zisinga okutambuza M ne DM..
 
Secondary sulfonamide accelerators ezirina obukuumi obulungi mu kulongoosa, sipiidi ya vulcanization ey’amangu n’ebintu eby’omubiri eby’amaanyi n’ebyuma bitwala ekifo ekisooka mu bika by’okusannyalala ebikozesebwa mu kukola emipiira. eby’amangu ebitera okukozesebwa mulimu MBS/BS, TBBS/NS, CBS/CZ, DCBS/DZ.
 
MBS produces nitrosamine, which has been discontinued by tire enterprises in western developed countries and regions and is still used in China.In the production of tires often add a small amount of thiuram type accelerator as the second accelerator, the commonly used variety is disulfide tetramethylthiuram TMTD, the product can produce nitrosamines.The common variety of sulfur donors is DTDM, era ekola nitrosamines.
 
Ebintu byonna ebisookerwako ebisatu ebiwandiikiddwa waggulu bisobola okuvaamu nitrosamines ez’obulabe eri obulamu bw’abantu. okutuuka ku mateeka agalangirirwa EU kirambikiddwa bulungi nti okukozesa ebigimusa ebyo waggulu kikugirwa ku bintu ebifulumizibwa mu EU.ebino wammanga bye bimu ku bintu ebiwerako ebiyinza okusoboka era ebikuuma obutonde bw’ensi okusobola okujuliza:
 
1. TBBS/NS esobola okukozesebwa mu kifo ky'ekyo, naye CTP esingawo anti-coke erina okugattibwako;
 
2. TBSI esobola okukozesebwa mu kifo kya n-tert-bulyl-bis (2-benzothiazole) sulfonamide . coking eri wakati wa NOB ne DZ, ate ebbeeyi eri wansi nnyo.tbsi erinnya ly'eddagala n-tert-butyl-bis, {{10} benzothia) promoter.This product has the characteristics of prolonging coking time and slowing down vulcanization rate when used in rubber.TBSI compared with TBBS, due to the large molecular weight, good thermal stability, melting temperature is above 30℃ higher than TBSS, scorch time is long, curing speed, etc.At present, TBSS is commonly used with CTP, and TBSI can completely replace TBBS+CTP.Okugatta ku ekyo, TBSI enywevu mu mazzi era nnyangu okutereka.okuziyiza okukendeeza kwa kapiira ak’obutonde aka vulcanized kwalongooseddwa mu ngeri etegeerekeka.kola bulungi mu kirungo ekikwatagana ne waya ya kapiira n’ekyuma.Esaanira elasomers zonna, naddala olw’ebintu ebinene ebyetaagisa okukendeera okw’amaanyi{20}}
 
3. Kiyinza okukyusibwamu CBBS, ekitajja kufulumya promoter ya N-nitrosamines. bwe kidda mu kifo kya NOBs mu muwendo gwe gumu, omuwendo gwayo ogw’okufuuka vulcanization gwenkanankana ddala{3}}Okukookoka okwokya omulimu gusingako katono ku NOBs ne CZ, eby’omubiri bya Vulcanizates era nobs nabyo biba bituufu nnyo ku mupiira gw’ekibuga n’ebintu ebirala ebya CZ{. eby’omubiri ebiwuniikiriza era nobs nabyo bituukira ddala ku bipiira by’ekibuga n’ebirala ebiriko {4}. eby’omubiri ebiyitibwa Vulcanizates era nobs nabyo bituukira ddala ku bipiira by’ekibuga era nga bisinga ku bipiira {4} eby’omubiri {4}.
 
4. XT580 esobola okukozesebwa mu kifo ky'ekyo, N-aliphatic benzothiazol-sulfonamide, omulimu gwayo gugeraageranyizibwa ddala ku NOBs, ate nga teguliimu butwa, ebbeeyi eri wansi okusinga NOBS.
 
· Promoter MBS/BS:
· Ekyuma ekikuba amasannyalaze TMTD:
1. TBZTD (tetrasulphide Benzylthiuram) esobola okukozesebwa mu kifo ky'ekyo, n'obukuumi bwa coke obulungi n'okulwanyisa okuddamu;erinnya lya tbztd ye tetrasulfide benzyl thiuram, abbreviated tbztd.product eno ye thiuram type type accelerator, which can tmtddd (which tmtddd(ththirude) tHETHETHETHETHETHETHETHETHETHIDELY (which can tmtddd (kisobola tmtdd) tMatfled (kisobola thamulfle) tMtflet tMtDD be used as the main accelerator or assistant accelerator for quick vulcanization of natural rubber, butadiene butadiene rubber and butadiene butadiene rubber. It has better processing safety and longer burning time than TMTD.Due to the large molecular weight of TBZTD, melting point is high, it is difficult to decompose, so there will be no nitrosamine, especially TBZTD only slightly lower than Sipiidi y’okuwonya eya TMTD, eby’obutonde ebirala kumpi bye bimu ne TMTD, bifuuse obusobozi bungi nnyo mu kukulaakulanya ekika ekipya eky’ekisannyalazo kya thiuram sulfide.
 
· Omukozi w’okuwonya DTDM:
1. Can use DTDC (N, N '- disulfide generation of caprolactam), a white crystalline shape, melting point is 120 ~ 122℃, active sulphur quality score greater than 0 19.It can replace the curing agent DTDM by the same amount without changing the formula and process of the compound.Similar to curing agent DTDM, curing agent DTDC can completely or partially replace sulfur to form effective or semi-effective curing system.As the vulcanizing agent DTDC can release active sulfur under the general vulcanization condition and form single sulfur bond and double sulfur bond between the added sulfur and rubber molecules, this rubber vulcanization network structure can endowing the vulcanized rubber with excellent heat resistance, compressibility and high tensile stress.DTDC is the best Vulcanizing agent for tire n’ebintu ebirala ebinene eby’omulembe ebya kapiira, ebintu ebiziyiza ebbugumu, ebintu bya kapiira eby’obuyonjo n’ebintu bya langi ebya langi{10}}
 
2. alkyl phenol disulfide (vultac-5) esobola okukozesebwa mu kifo kya alkyl phenol disulfide, esaanira enkola z’okugatta kwa kapiira ez’oludda olw’enjawulo olwa polarity n’oludda lw’omupiira omweru.
 
3. Amasavu polysulfide gayinza okukozesebwa mu kifo ky'ekyo.
