Kufotokozera
2-Mercaptobenzothiazole ndi mankhwala okhala ndi formula ya C7H5NS2. Zowala zachikasu za monoclinic zokhala ngati singano kapena ngati makhiristo ngati masamba. Kusungunuka mu glacial acetic acid, sungunuka mu alkali ndi carbonate solution, osasungunuka m'madzi. Amamva kuwawa komanso fungo losasangalatsa.
Ntchito
Monga vulcanization accelerator-cholinga chonse, mankhwalawa amagwiritsidwa ntchito kwambiri mu rubbers osiyanasiyana. Vulcanization accelerator ya mphira wachilengedwe ndi mphira zopangira nthawi zambiri zimatenthedwa ndi sulfure. Komabe, iyenera kuyendetsedwa ndi zinc oxide, mafuta acid, etc. musanagwiritse ntchito. Nthawi zambiri amagwiritsidwa ntchito limodzi ndi machitidwe ena accelerator, monga dithiothiuram ndi tellurium dithiocarbamate, angagwiritsidwe ntchito ngati vulcanization accelerator kwa mphira wa butyl; itha kugwiritsidwa ntchito limodzi ndi tribasic lead maleate kwa mtundu wopepuka Madzi osamva chlorosulfonated polyethylene pawiri. Nthawi zambiri amagwiritsidwa ntchito limodzi ndi dithiocarbamate mu latex, ndipo akagwiritsidwa ntchito limodzi ndi diethylamine diethyldithiocarbamate, amatha kutenthedwa kutentha. Mankhwalawa ndi osavuta kumwazikana mu rabala ndipo samaipitsa. Komabe, chifukwa cha kukoma kwake kowawa, sikoyenera kugwiritsidwa ntchito pazakudya zopangira mphira. Accelerator M ndi yapakatikati ya ma accelerators MZ, DM, NS, DIBS, CA, DZ, NOBS, MDB, ndi zina zotero, 2-mercaptobenzothiazole yokhala ndi 1-amino-4-nitroanthraquinone ndi potassium carbonate mu dimethyl Reflux mu formamide kwa 3h, dye anabalalitsa redCI2 brilliant SGL (Red 1) Red-Disperse canale.
Utoto uwu umagwiritsidwa ntchito popenta poliyesitala ndi nsalu zake zosakanikirana. 2-mercaptobenzothiazole ikagwiritsidwa ntchito ngati chowonjezera cha electroplating, imatchedwanso acid copper plating brightener M, ndipo imagwiritsidwa ntchito ngati chowunikira pakuyika kwa mkuwa wonyezimira ndi copper sulfate monga mchere waukulu.
Kuonjezera apo, mankhwalawa amagwiritsidwanso ntchito pokonzekera mankhwala ophera tizilombo ndi fungicides, ma synergists a nayitrogeni feteleza, mafuta odula ndi zowonjezera zowonjezera, organic anti-ashing agents mu chemistry yojambula zithunzi, inhibitors zitsulo zowonongeka, etc. Komanso, ndi reagent ya kusanthula mankhwala. Mankhwalawa ndi otsika kawopsedwe ndipo amakhala ndi zotsatira zoyipa pakhungu ndi mucous nembanemba.
Amagwiritsidwa ntchito ngati reagent tcheru ndi mphira accelerator kudziwa golide, bismuth, cadmium, cobalt, mercury, faifi tambala, lead, thallium ndi zinki.
Amagwiritsidwa ntchito makamaka popanga matayala, machubu amkati, matepi, nsapato za mphira ndi zinthu zina za mphira zamakampani.
Izi ndi imodzi mwazoletsa corrosion inhibitors zamkuwa kapena aloyi yamkuwa. Pamene kuzizira kumakhala ndi zipangizo zamkuwa ndipo madzi osaphika ali ndi ayoni amkuwa, mankhwalawa akhoza kuwonjezeredwa kuti ateteze dzimbiri zamkuwa.
2-Mercaptobenzothiazole ndi wapakatikati wa herbicide fenthiofen, komanso chothamangitsira mphira ndi chapakatikati.
Amagwiritsidwa ntchito makamaka ngati chowunikira chamkuwa wonyezimira wa sulfate. Zili ndi zotsatira zabwino zowongolera. Mlingo wamba ndi 0.05 ~ 0.10 g/L. Itha kugwiritsidwanso ntchito ngati chowunikira cha cyanide silver plating. Pambuyo powonjezera 0,5 g / L, polarizability ya cathode ikuwonjezeka, ndipo makhiristo a ayoni asiliva amawongolera ndikukonzedwa kuti apange wosanjikiza wonyezimira wa siliva.
