Inkcazo
I-2-Mercaptobenzothiazole yikhemikhali ene-molecular formula C7H5NS2. Ukukhanya okutyheli kwemonoclinic okufana nenaliti okanye iikristale ezifana negqabi. I-soluble kwi-glacial acetic acid, i-soluble kwi-alkali kunye nesisombululo se-carbonate, enganyibiliki emanzini. Inencasa ekrakrayo kwaye inevumba elibi.
Umsebenzi
Njengenjongo ye-vulcanization accelerator, le mveliso isetyenziswa ngokubanzi kwiirubha ezahlukeneyo. I-vulcanization accelerator yerabha yendalo kunye neerubha ezenziweyo zidla ngokuvulcaniswa nesalfure. Nangona kunjalo, kufuneka isebenze nge-zinc oxide, i-fatty acid, njl. phambi kokusetyenziswa. Ngokuqhelekileyo isetyenziselwa ukudibanisa nezinye iinkqubo ze-accelerator, ezifana ne-dithiothiuram kunye ne-tellurium dithiocarbamate, inokusetyenziswa njenge-vulcanization accelerator ye-rubber ye-butyl; inokusetyenziswa ngokudityaniswa ne-tribasic lead maleate yombala okhanyayo Amanzi amelana ne-chlorosulfonated polyethylene ikhompawundi. Ihlala isetyenziswa ngokudibeneyo ne-dithiocarbamate kwi-latex, kwaye xa isetyenziswe ngokudibanisa ne-diethylamine diethyldithiocarbamate, inokuthi ifakwe kwiqondo lokushisa eliqhelekileyo. Imveliso ilula ukusabalalisa kwi-rubber kwaye ayingcolisi. Nangona kunjalo, ngenxa yokunambitheka kwayo okukrakra, ayifanelekanga ukusetyenziswa kwiimveliso zerabha zoqhagamshelwano. I-Accelerator M iphakathi kwe-accelerators i-MZ, i-DM, i-NS, i-DIBS, i-CA, i-DZ, i-NOBS, i-MDB, njl., i-2-mercaptobenzothiazole kunye ne-1-amino-4-nitroanthraquinone kunye ne-potassium carbonate kwi-dimethyl Reflux kwi-formamide ye-3h, i-dayi edibeneyo i-Red-Disperse i-RedCI2 i-Red-Disperse i-Red GLlliant i-Red GLlliant i-Red.
Le dayi isetyenziselwa ukudaya ipolyester namalaphu ayo axutyiweyo. Xa i-2-mercaptobenzothiazole isetyenziswa njenge-electroplating additive, ikwabizwa ngokuba yi-acid copper plating brightener M, kwaye isetyenziswa njenge-ejenti ekhanyayo yokufakwa kwe-copper sulfate njengeyona tyuwa iphambili.
Ukongezelela, imveliso isetyenziselwa ukulungiselela i-pesticides kunye ne-fungicides, i-nitrogen fertilizer synergists, i-oyile yokusika kunye ne-lubricant additives, i-organic anti-ashing agents kwi-photographic chemistry, i-metal corrosion inhibitors, njl. Ukongeza, i-reagent yohlalutyo lweekhemikhali. Imveliso iphantsi kwi-toxicity kwaye inefuthe elicasulayo kwesikhumba kunye ne-mucous membranes.
Isetyenziswa njenge-reagent ebuthathaka kunye ne-accelerator yerabha yokumisela igolide, i-bismuth, i-cadmium, i-cobalt, i-mercury, i-nickel, ilothe, i-thallium kunye ne-zinc.
Isetyenziswa kakhulu ekwenzeni amatayara, iityhubhu zangaphakathi, iiteyiphu, izihlangu zerabha kunye nezinye iimveliso zerabha zamashishini.
Le mveliso yenye ye-corrosion inhibitors esebenzayo yobhedu okanye i-alloy yobhedu. Xa inkqubo yokupholisa iqulethe izixhobo zethusi kunye namanzi akrwada aqulethe inani elithile le-ion zethusi, le mveliso inokongezwa ukukhusela ukubola kobhedu.
I-2-Mercaptobenzothiazole yindawo ephakathi ye-fenthiofen ye-herbicide, kunye ne-accelerator yerabha kunye ne-intermediate yayo.
Isetyenziswa kakhulu njenge-brightener ye-sulfate yobhedu eqaqambileyo. Unesiphumo esihle sokulinganisa. Idosi eqhelekileyo yi-0.05～0.10 g/L. Isenokusetyenziswa njengesikhanyisi kwiplating yesilivere yecyanide. Emva kokongeza i-0.5 g / L, i-polarizability ye-cathode iyanda, kwaye iikristali ze-ion zesilivere zijoliswe kwaye zilungiselelwe ukuba zenze uluhlu olukhanyayo lwesiliva-plating.
