Tsanangudzo
2-Mercaptobenzothiazole ikemikari ine molecular formula C7H5NS2. Chiedza cheyero monoclinic tsono-yakafanana kana mashizha-sekristaro. Soluble muglacial acetic acid, inonyungudika mualkali uye carbonate solution, isinganyunguriki mumvura. Ane chinovava uye ane hwema isingafadzi.
Function
Seyakajairwa-chinangwa vulcanization accelerator, ichi chigadzirwa chinoshandiswa zvakanyanya mumarabha akasiyana. Vulcanization accelerator yerabha yechisikigo uye marabha ekugadzira anowanzo kupiswa nesarufa. Zvisinei, inoda kushandiswa ne zinc oxide, mafuta acid, nezvimwe zvisati zvashandiswa. Inowanzoshandiswa pamwe chete nemamwe masisitimu accelerator, akadai se dithiothiuram uye tellurium dithiocarbamate, inogona kushandiswa sevulcanization accelerator ye butyl rubber; inogona kushandiswa pamwe chete ne tribasic lead maleate kune yakareruka ruvara Mvura inodzivirira chlorosulfonated polyethylene compound. Inowanzoshandiswa pamwe chete ne dithiocarbamate mu latex, uye kana yakashandiswa pamwe chete nediethylamine diethyldithiocarbamate, inogona kuvharidzirwa pamhepo yekupisa. Chigadzirwa chacho chiri nyore kuparadzira murubha uye hachisvibise. Nekudaro, nekuda kwekuravira kwayo kunorwadza, haina kukodzera kushandiswa mune chikafu chekubata rubber zvigadzirwa. Accelerator M inzvimbo yepakati ye accelerators MZ, DM, NS, DIBS, CA, DZ, NOBS, MDB, nezvimwewo, 2-mercaptobenzothiazole ine 1-amino-4-nitroanthraquinone uye potassium carbonate mu dimethyl Reflux mu formamide ye3h, iyo dhayi inoparadzira red-disperse GL12Red disperse GL1 (Red CZ).
Dhayi iyi inoshandiswa kudhaya polyester nemachira ayo akasanganiswa. Kana 2-mercaptobenzothiazole inoshandiswa se electroplating additive, inodaidzwa zvakare kuti acid copper plating brightener M, uye inoshandiswa sechinhu chinopenya chendarira inopenya ine copper sulfate semunyu mukuru.
Mukuwedzera, chigadzirwa chacho chinoshandiswawo kugadzirira mishonga yezvipembenene uye fungicides, nitrogen fertilizer synergists, kutema mafuta uye lubricant additives, organic anti-ashing agents mu photographic chemistry, metal corrosion inhibitors, etc. Mukuwedzera, iyo reagent yekuongorora kemikari. Chigadzirwa chacho chakaderera muhupfu uye chine chinogumbura chinokanganisa paganda uye mucous membranes.
Inoshandiswa seyakajeka reagent uye rubber accelerator yekusimbisa goridhe, bismuth, cadmium, cobalt, mercury, nickel, lead, thallium uye zinc.
Inonyanya kushandiswa mukugadzira matai, machubhu emukati, matepi, shangu dzerabha uye zvimwe zvigadzirwa zverabha zveindasitiri.
Ichi chigadzirwa ndeimwe yeanoshanda corrosion inhibitors yemhangura kana mhangura alloy. Kana iyo yekutonhodza iine midziyo yemhangura uye mvura yakasvibira ine imwe huwandu hwemaoni emhangura, chigadzirwa ichi chinogona kuwedzerwa kudzivirira kukora kwemhangura.
2-Mercaptobenzothiazole inhengo yepakati yemushonga wefenthiofen, pamwe nerubber accelerator uye yepakati.
Inonyanya kushandiswa seinopenya kune inopenya mhangura sulfate. Iine yakanaka yekuyera mhedzisiro. Huwandu hwedosi ndeye 0.05 ~ 0.10 g/L. Inogona zvakare kushandiswa seinopenya yecyanide sirivheri plating. Mushure mekuwedzera 0.5 g / L, iyo polarizability ye cathode inowedzera, uye makristasi eioni esirivha anotarirwa uye anorongwa kuti aite chidimbu chakajeka chesirivha-plating.
