Kev piav qhia
2-Mercaptobenzothiazole yog ib yam tshuaj nrog cov mis mos molecular C7H5NS2. Lub teeb daj monoclinic koob zoo li los yog nplooj zoo li muaju. Soluble nyob rau hauv glacial acetic acid, soluble nyob rau hauv alkali thiab carbonate kua, insoluble nyob rau hauv dej. Nws muaj ib tug iab saj thiab muaj ib tug unpleasant tsw.
Muaj nuj nqi
Raws li lub hom phiaj dav dav vulcanization accelerator, cov khoom no tau siv dav hauv ntau yam roj hmab. Vulcanization accelerator rau cov roj hmab ntuj thiab hluavtaws roj hmab feem ntau vulcanized nrog leej faj. Txawm li cas los xij, nws yuav tsum tau qhib los ntawm zinc oxide, fatty acid, thiab lwm yam ua ntej siv. Feem ntau siv ua ke nrog lwm lub tshuab accelerator, xws li dithiothiuram thiab tellurium dithiocarbamate, nws tuaj yeem siv los ua vulcanization accelerator rau butyl roj hmab; Nws tuaj yeem siv ua ke nrog tribasic lead maleate rau lub teeb xim Dej chlorosulfonated polyethylene compound. Nws feem ntau yog siv ua ke nrog dithiocarbamate hauv latex, thiab thaum siv nrog rau kev sib xyaw nrog diethylamine diethyldithiocarbamate, nws tuaj yeem ua vulcanized ntawm chav tsev kub. Cov khoom yog yooj yim rau disperse nyob rau hauv roj hmab thiab tsis muaj kuab paug. Txawm li cas los xij, vim nws qhov iab saj, nws tsis haum rau siv hauv cov khoom noj khoom haus sib cuag roj hmab. Accelerator M yog ib qho nruab nrab ntawm accelerators MZ, DM, NS, DIBS, CA, DZ, NOBS, MDB, thiab lwm yam., 2-mercaptobenzothiazole nrog 1-amino-4-nitroanthraquinone thiab potassium carbonate hauv dimethyl Reflux hauv formamide rau 3h, cov dye-brilliantis disperse 121) tuaj yeem tau txais.
Cov xim no yog siv rau dyeing polyester thiab nws cov ntaub sib xyaw. Thaum 2-mercaptobenzothiazole siv los ua cov khoom siv electroplating, nws tseem hu ua kua qaub tooj liab plating brightener M, thiab siv los ua tus neeg sawv cev ci ci rau ci tooj liab plating nrog tooj liab sulfate ua cov ntsev tseem ceeb.
Tsis tas li ntawd, cov khoom kuj tseem siv los npaj cov tshuaj tua kab thiab fungicides, nitrogen chiv synergists, txiav cov roj thiab lubricant additives, organic anti-ashing agents nyob rau hauv photographic chemistry, hlau corrosion inhibitors, thiab lwm yam. Tsis tas li ntawd, nws yog ib tug reagent rau tshuaj ntsuam xyuas. Cov khoom no tsis tshua muaj toxicity thiab muaj kev cuam tshuam rau ntawm daim tawv nqaij thiab mucous daim nyias nyias.
Siv los ua rhiab heev reagent thiab roj hmab accelerator rau kev txiav txim ntawm kub, bismuth, cadmium, cobalt, mercury, npib tsib xee, lead, thallium thiab zinc.
Feem ntau siv rau hauv kev tsim cov log tsheb, cov raj sab hauv, cov kab xev, cov khau roj hmab thiab lwm yam khoom siv roj hmab.
Cov khoom no yog ib qho zoo corrosion inhibitors rau tooj liab lossis tooj liab alloy. Thaum lub tshuab cua txias muaj cov khoom siv tooj liab thiab cov dej nyoos muaj qee qhov tooj liab ions, cov khoom no tuaj yeem muab ntxiv los tiv thaiv tooj liab corrosion.
2-Mercaptobenzothiazole yog ib qho nruab nrab ntawm cov tshuaj herbicide fenthiofen, nrog rau cov roj hmab accelerator thiab nws cov nruab nrab.
Feem ntau yog siv los ua brightener rau ci tooj liab sulfate. Nws muaj cov nyhuv leveling zoo. Cov koob tshuaj dav dav yog 0.05 ~ 0.10 g / L. Nws kuj tseem siv tau los ua lub ci ci rau cyanide silver plating. Tom qab ntxiv 0.5 g / L, lub polarizability ntawm lub cathode yog nce, thiab cov muaju ntawm cov nyiaj ions yog taw qhia thiab npaj los tsim ib lub ci nyiaj-plating txheej.
