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 ukuthi icushwe yi-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 esimaphakathi esingu-MZ, DM, NS, DIBS, CA, DZ, NOBS, MDB, njll., 2-mercaptobenzothiazole ene-1-amino-4-nitroanthraquinone kanye ne-potassium carbonate ku-dimethyl Reflux ku-formamide 3h, idayi i-disperse red brilliant S-GL (CIDisperse Red 121) ingatholakala.
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 ungenye ye-corrosion inhibitors ephumelelayo ye-copper noma i-alloy yethusi.Lapho uhlelo lokupholisa luqukethe izinto zethusi futhi amanzi aluhlaza aqukethe inani elithile lama-ion ethusi, lo mkhiqizo ungengezwa 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 njengento ekhanyayo 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.
