Incazelo
I-2-Mercaptobenzothiazole iyikhemikhali enefomula ye-molecular C7H5NS2. Amakristalu aphuzi afana nenaliti noma anjengeqabunga. Incibilika ku-glacial acetic acid, inyibilika kusisombululo se-alkali nese-carbonate, engancibiliki emanzini. Inokunambitheka okubabayo futhi inephunga elingemnandi.
Umsebenzi
Njengesisheshisi senhloso evamile, lo mkhiqizo usetshenziswa kakhulu kumarabha ahlukahlukene. I-Vulcanization accelerator yenjoloba yemvelo kanye namarabha okwenziwa ngokuvamile avuthwa ngesibabule. Kodwa-ke, idinga ukwenziwa kusebenze i-zinc oxide, i-fatty acid, njll. ngaphambi kokusetshenziswa. Isetshenziswa kaningi ngokuhlanganiswa nezinye izinhlelo ze-accelerator, njenge-dithiothiuram ne-tellurium dithiocarbamate, ingasetshenziswa njenge-vulcanization accelerator yerabha ye-butyl; ingasetshenziswa ihlanganiswe ne-tribasic lead maleate yombala okhanyayo Inhlanganisela yamanzi ye-chlorosulfonated polyethylene. Ivamise ukusetshenziswa ekuhlanganisweni ne-dithiocarbamate ku-latex, futhi uma isetshenziswa ihlanganiswe ne-diethylamine diethyldithiocarbamate, ingafakwa engozini ekamelweni lokushisa. Umkhiqizo kulula ukuwuhlakaza erabha futhi awungcolisi. Kodwa-ke, ngenxa yokunambitheka okubabayo, akufanelekile ukusetshenziswa emikhiqizweni yenjoloba yokuxhumana nokudla. I-Accelerator M iyisishicileli esiphakathi nendawo i-MZ, DM, NS, DIBS, CA, DZ, NOBS, MDB, njll., 2-mercaptobenzothiazole ene-1-amino-4-nitroanthraquinone ne-potassium carbonate ku-dimethyl Reflux ku-formamide isikhathi esingu-3h, i-reddisperse red12Disperse GL1 i-Red GL etholwe i-Red GLlliant.
Lo dayi usetshenziselwa ukudaya i-polyester nezindwangu zayo ezihlanganisiwe. Uma i-2-mercaptobenzothiazole isetshenziswa njengesengezo se-electroplating, ibizwa nangokuthi i-acid copper plating brightener M, futhi isetshenziswa njenge-ejenti ekhanyayo yokucwebezela kwethusi okukhanyayo nge-copper sulfate njengosawoti oyinhloko.
Ngaphezu kwalokho, umkhiqizo usetshenziselwa ukulungisa izibulala-zinambuzane kanye nama-fungicides, ama-synergists omanyolo we-nitrogen, amafutha okusika kanye nezithasiselo zokugcoba, ama-organic anti-ashing agents kumakhemikhali ezithombe, ama-metal corrosion inhibitors, njll Ngaphezu kwalokho, i-reagent yokuhlaziywa kwamakhemikhali. Umkhiqizo unobuthi obuncane futhi unomphumela ocasulayo esikhumbeni kanye nolwelwesi lwamafinyila.
Isetshenziswa njenge-reagent ezwelayo kanye ne-accelerator yerabha ekunqumeni igolide, i-bismuth, i-cadmium, i-cobalt, i-mercury, i-nickel, i-lead, i-thallium ne-zinc.
Ikakhulukazi esetshenziswa ekwenzeni amathayi, amashubhu angaphakathi, amateyipu, izicathulo zenjoloba neminye imikhiqizo yenjoloba yezimboni.
Lo mkhiqizo ungomunye we-corrosion inhibitors esebenzayo yethusi noma i-alloy yethusi. Lapho uhlelo lokupholisa luqukethe izinto zethusi futhi amanzi aluhlaza aqukethe inani elithile lama-ion ethusi, lo mkhiqizo ungangezwa ukuvimbela ukugqwala kwethusi.
I-2-Mercaptobenzothiazole iyisithako esimaphakathi somuthi we-herbicide fenthiofen, kanye ne-accelerator yerabha kanye nendawo yayo emaphakathi.
Ikakhulukazi isetshenziswa njenge-brightener ye-sulfate yethusi ekhanyayo. Inomphumela omuhle wokulinganisa. Umthamo ojwayelekile ngu-0.05–0.10 g/L. Ingasetshenziswa futhi njenge-brightener ye-cyanide silver plating. Ngemuva kokwengeza i-0.5 g / L, i-polarizability ye-cathode iyanda, futhi amakristalu e-ion esiliva aqondiswe futhi ahlelwe ukuze enze ungqimba olukhanyayo lwesiliva-plating.
