Cov accelerators yog condensates ntawm aliphatic aldehydes los amines (aliphatic los yog ntxhiab amines). Nws yog acidic. Thaum lub ntau yam yog txawv, lawv ua si vulcanization thiab cov tau txais vulcanization zog yog txawv. Nws qhov kev ua si feem ntau yog ranges los ntawm quasi-super kom qeeb. Nws muaj zoo nyob thiab lub sij hawm scorch yog tsis ntev. Qhov tseem ceeb tshaj plaws yog tias cov khoom siv tau los ntawm vulcanized muaj kev laus ua haujlwm zoo heev. Ntawm lawv, ib tug tsis tshua muaj zog txhawb nqa (xws li hexamethylenetetramine) yog siv ob qho kev txhawb ntxiv thiazole los yog sulfenamide accelerators. Tsuas yog lub butyraldehyde aniline condensate yog ib qho muaj zog accelerator thiab ua raws li tus thawj accelerator thaum nws yog tsim nrog thiuram accelerator. (1) Hexamethylenetetramine Lub npe pauv no yog tus neeg txhawb H. Cov khoom no yog xim dawb crystalline hmoov, yuav luag tsw ntxhiab thiab ntsim. Nws muaj cov nyhuv rau ntawm daim tawv nqaij. Qhov kev nqus yog 1.3. Cua kub rau 263 ° C yuav sublimate thiab ib nrab decompose. Me ntsis deliquescent. Qhov kub hnyiab tseem ceeb yog 140 ° C. Thaum ntsuas kub tsawg, nws tsis heev, thiab kev pheej hmoo ntawm scorch yog me me. Siv feem ntau yog qhov thib ob lub zog. Tsis muaj kev sib thooj, tsis muaj kuab paug, tsis muaj kev lwj siab. Feem ntau yog siv cov pob tshab thiab cov khoom sib xws. (2) n-Butylaldehyde thiab aniline condensate Lub npe pev xaj yog lub tshuab ua zog 808. Cov khoom no yog xim liab los yog kua txiv hmab ntsev oily kua roj nrog ib tus ntxhiab tsw. Qhov kev faib ua ke yog 0.94 ~ 0.98. Nyob rau hauv cov huab cua, qhov xim ua ib tsos tsaus tsawv thiab qhov kev nqus loj tuaj. Tab sis qhov kev ua tau zoo li qub. Raug rho tawm huab cua txias yog ruaj khov. Lub qhov uas nyob ntawm qhov chaw nyob yog siab heev, qhov kub hnyiab tseem ceeb yog 120 ° C, thiab qhov ntsuas qhov zoo tshaj plaws yog 120-160 ° C. Zoo dispersibility hauv cov kua nplaum. Haum rau roj hmab thiab tawv roj hmab uas muaj cov roj hmab rub rov qab.
Sunnyjoint HMT-3H thiab HMT-10 rau ntau lub log tsheb, xws li Hankook, Michelin.Nexex thiab lwm yam.
