Nk’uko twese tubizi, MBS / NOBS, TMTD, DTDM n’ibindi bikoresho vyo kwihutisha mu nzira yo hagati ya sulfide bizobora kanseri y’ibihimba vy’irondoka, ni gute yohitamwo ubundi buryo? Ushaka kwemera uburyo bwo gukiza ibidukikije kugira ngo ushobore guhangana n’ishirahamwe ry’ubumwe bw’Uburayi, raba aha hepfo!
Ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivy’amapine nk’ivy’ivyinjizwa vy’amapine nk’ivy’ivyihuta vy’inyuma vy’imbere cane cane, ivy’ukuri ni bike, ugukoresha nyamukuru kw’umurongozi M na DM{2.
Igikoresho co gutera imbere mu mubiri coroshe gukora kandi gitekanye, umuvuduko wo gukiza ningoga n’imiterere y’umubiri n’ubuhinga bwo hejuru y’umubiri w’imbere mu mubiri, ni ukuvuga ubwoko bw’ivyuma vy’ivyuma vy’ivyuma, ivyuma bikoreshwa cane harimwo MBS / NOBS, TBBS / NS, CBS / CZ, DCBS / DZ{0}}
MBS itanga nitrosamines, abahinguzi b’amapine mu bihugu vyateye imbere mu burengero n’uturere vyahagaze hakoreshejwe igikoresho co gutera imbere, urugo ruracariko rurakoresha iki kintu . Tire kenshi yongerako thiuram gatoyi nk’igikoresho ca kabiri c’ivyuma vy’ivyuma, ubwoko bukoreshwa cane ni umuyagankuba w’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma (nitrosamines TMTD, igicuruzwa gishobora gutanga nitrosamines. Ubwoko rusangi bukoreshwa mu . abatanga ikirahuri ni ditiodorphorphine DTDM, na yo nyene itanga nitrosamines.
Ubwo bwoko butatu bw’ibikoresho vya mbere burashobora gutanga nitrosamines zishobora gutera ingorane ubuzima bw’abantu, ishirahamwe ry’ubumwe bw’Uburayi ryavuze neza ko amategeko ya REACH yasavye neza ko ibintu vyarungikwa hanze mu bijanye n’ugubuza gukoresha ibikoresho vya mbere biri hejuru. ibi bikurikira ni bimwe mu bishobora gukoreshwa mu buryo bundi bwo gukoresha ibidukikije kugira ngo umuntu ashobore gukoresha:
1 ishobora gukoreshwa aho gukoresha TBBS / NS, ariko ikeneye kwongerako CTP y’ugurwanya scorch;
2. Aho kuba TBSI, N-tert-buy-bus (2- Ab-terzothiazole) igiti c’umuberoshi hagati ya NOBS na DZ, igiciro ni gito cane . Izina ry’imiti ry’i TBRI Nt-bis ({8}bynzothiazole) ryihutisha, ry’agaciro nk’i TBI, na ryo nyene ni sulfatemide accelerator . Iki kintu gikoreshwa mu bikoresho vy’ipulasitike kugira ngo umuntu ashireho igihe c’ugucapura n’ibiranga igipimo c’umuti buhoro buhoro. TBSI ugereranyije na TBBS, kubera uburemere bwayo bukomeye bw’ibihimba, ugushikama neza kw’ubushuhe, ahantu h’ugushonga cane kuruta TBS 30 degre , n’igihe kirekire c’ugusuka n’ibindi kuri . Kuri ubu, TBSS ikoreshwa kenshi na CTP y’i TBS + . CTP yonyene. Kwongera TBSI na yo nyene irafise amazi ahagaze, yoroshe kubika; cane gutuma habaho uguhinduka kw’imipira y’imipira y’imipira y’imipira; mu bikoresho vyo gufatanya n’imipira n’ivyuma bikora neza; birashobora gukoreshwa ku bikoresho vyose vy'elastomer, cane cane ku kurwanya ibisabwa vyo kugabanya ibintu vy'agaciro kanini n'ibindi kuri .
3. CBS ishobora gukoreshwa aho gukoresha, ntizotanga N-nitrosamines accelerator, ingana no gusubirira NOBS, igipimo c’uguhindura ni {. Gukora neza gatoyi kuruta NOBS na CZ, imiterere y’imipira y’imipira n’ibindi bikoresho vy’umubiri na vyo nyene birakoreshwa cane mu mapine y’ibisagara n’ibindi bikoresho vy’imipira.
4. Ishobora gukoreshwa mu kibanza ca XT580, N-futty benzothiazole sulfnamide, ibikorwa vyayo vyose bingana n’ivyo NOBS, ariko kandi n’ukutagira ubumara, igiciro kiri hasi y’i NOBS .
Umukozi MBS / NOBS:
TMTD:
1. TBZTD (idini y’itetrabenzylthuram) ishobora gukoreshwa aho gukoreshwa, n’umutekano mwiza n’ukurwanya ugusubira inyuma; Izina rya TBZTD ni tetrabenzylthiuram, ryakozwe na TBZTD. Iki kintu ni ikintu gishasha categuwe gishobora gusubirira TMTD (ki tetramethyldiuldiuldiuldaldilfide) kandi gishobora gukoreshwa nk’igikoresho nyamukuru co gutera imbere canke co gukorana n’abandi kugira ngo umuntu ashobore gutera imbere ningoga kw’ivyuma vy’agaciro, umunyu w’umukara n’ styrene-butadiene piber . Gukora biratekanye kandi bifise umwanya muremure kuruta TMTD. Kubera uburemere bwayo bukomeye bw’amamolekule, igipimo kinini c’ugushonga n’ugubora bigoye, TBZTD ntitanga nitrosamine . TBZTD, cane cane, ifise igipimo gitoyi gatoyi kuruta TMTD. Y’ibindi bimenyetso vyayo ni nk’ivyo TMTD . Vyacitse ikintu ciza cane co gutera imbere mu bijanye n'ubuhinga bwa Vulcane .
Gutera imbere DTDM:
1. DTDC (N, N'-dithio caprolactam) can be used instead of white crystalline form, the melting point of 120 ~ 122℃, the active sulfur mass fraction greater than 0 19. With its equivalent replacement curing agent DTDM, without changing the formula and process rubber. Like the vulcanizing agent DTDM, the vulcanizing agent DTDC can replace all or igice c’ikibiriti kugira ngo haboneke uburyo bwiza canke bushobora gutuma umuntu agira ubushobozi bwo gutera umunyu mu gihe c’ubuhumane bw’ikibiriti DTDC kandi irafise ibiranga ukudatera, gukingira, gukiza umuvuduko, ni umuvuduko w’ipine n’ibindi bikoresho bininibinini vy’imipira, ibintu bishobora guhangana n’ubushuhe, ibintu vy’imipira y’imipira n’ibintu vy’amabara, igikoresho co gukiza neza cane.
2. Alkyl phenol diulfide (VULTAC-5) ishobora gukoreshwa aho gukoresha, disulifide ya alkyl phenol, ibereye ku nzira itandukanye y'imipira y'amazi n'uruhome rw'inyuma .
3. Aho gukoresha polysulfides z'aliphatic.
