Sodium mercaptobenzothiazole, CAS nhamba 2492-26-4, yakapfupikiswa seSMBT, ine fomura yemamorekuru C7H4NNaS2. Sodium Mercaptobenzothiazole SMBT inowanzoonekwa seupfu hweyero kusvika kubrown kana granules, inonyungudika zvakanyanya mumvura, uye ine basa remakemikari rakasiyana. Mapoka anoshanda akadai semapoka ethiol (-SH) uye thiazole rings ari muchimiro chayo chemamorekuru anoipa hunhu hwakanaka hwekuumbwa kwayo, antioxidant uye vulcanization, zvichiita kuti iite basa risingatsiviwe muminda yakawanda yakadai seindasitiri yerabha, kugadzirisa simbi, kurapwa kwemvura, uye maindasitiri emishonga nemakemikari. Sodium Mercaptobenzothiazole SMBT chigadzirwa chakakosha chine mashandiro uye kushanda mumunda wemakemikari akanaka.

Kunyungudika kweSodium mercaptobenzothiazole kwakanaka mumvura uye mune alkaline solution, inonyungudika zvishoma mu organic solvents, sodium mercaptobenzothiazole inoshandiswa zvakanyanya inosanganisira rabha vulcanization accelerator, metal corrosion inhibitor uye intermediate in chemical synthesis.

I. Indasitiri yeRabha - Chikamu Chikuru chezvikurumidziso zveVulcanization Zvinoshanda Zvakanyanya

Muindasitiri yerabha,sodium mercaptobenzothiazolechinhu chakakosha chekushandisa vulcanization accelerators, chakakodzera kugadziriswa kwevulcanization yemarabha ekugadzira akadai serabha yechisikigo, rabha yestyrene-butadiene uye rabha yenitrile. Rubber vulcanization inzira inokosha umo mamorekuru erabha anoumba chimiro chenetwork chemativi matatu kuburikidza ne cross-linking reactions, nokudaro zvichiwedzera simba, kutwasuka, kuramba kupfeka uye kuramba kupisa kwezvigadzirwa zverabha. Sodium mercaptobenzothiazole, ine simba rayo guru re catalytic pa vulcanization reactions, yave chinhu chikuru mukuita uku.

Zvichienzaniswa nezvishandiso zvechinyakare zvekumhanyisa, sisitimu yekumhanyisa yakavakirwa pasodium mercaptobenzothiazole ine zvakanakira zvakaita sekumhanya kwekukurumidza kwe vulcanization, huwandu hwakafanana hwe crosslinking uye dosage shoma. Sodium mercaptobenzothiazole inogona kuderedza tembiricha ye vulcanization zvinobudirira, kupfupisa nguva ye vulcanization, kuwedzera zvakanyanya kushanda zvakanaka kwekugadzira, uye panguva imwe chete inovandudza hunhu hwezvigadzirwa zverabha, zvichiita kuti ishandiswe zvakanyanya mukugadzira zvigadzirwa zverabha zvakaita sematairi, zvisimbiso, mahosi erabha, uye mabhandi erabha. Pamusoro pezvo, inogona zvakare kuwedzerwa nezvimwe zvinomhanyisa (senge sulfenamides ne guanidins) kuti zvishandiswe. Fomura iyi inogona kugadziriswa zvichienderana nezvinodiwa zvekushanda kwezvigadzirwa zvakasiyana zverabha kuti iwedzere kugadzirisa vulcanization effect uye isangane nezvinodiwa zvemhando yepamusoro zvezvigadzirwa zverabha zvepamusoro.

II. Kushanda nesimbi – Zvidziviriri zveCorrosion zvinoshanda zvakanyanya uye zvinogadzirisa ngura

Maatomu ethiol neenitrogen ari mumorekuru yesodium mercaptobenzothiazole ane kugona kwakasimba kwekubatanidza uye anogona kugadzira macomplexes akagadzikana ane maion akasiyana-siyana esimbi (akadai semhangura, iron, zinc, nezvimwewo). Hunhu uhwu hunoita kuti iratidze kudzivirira ngura kwakanaka uye kushanda zvakanaka kwesimbi mukugadzirisa simbi.

Panyaya yekudzivirira ngura yesimbi uye kudzivirira ngura,SMBTinowanzo wedzerwa kuzvigadzirwa zvakaita sesimbi inochekwa mvura, mafuta ekudzivirira ngura, uye antifreeze. Kana yakabatana nesimbi, sodium mercaptobenzothiazole inogona kukurumidza kunyudza uye kugadzira firimu rekudzivirira rakakora, ichibvisa zvinhu zvinoparadza zvakaita seokisijeni nehunyoro kubva pamusoro pesimbi, nokudaro ichidzivirira ngura ye oxidation uye ngura ye electrochemical yesimbi, uye kuwedzera hupenyu hwebasa nenguva yekuchengetwa kwesimbi. Kunyanya mukugadzirisa nekudzivirira copper ne copper alloys, mhedzisiro yayo yekudzivisa ngura inonyanya kushamisa, iyo inogona kudzivirira zvinhu zve copper kubva mukuoxidation, kuchinja ruvara, mavara nezvimwe zviitiko zvekuora. SMBT inoshandiswa zvakanyanya mukudzivirira zvikamu zve copper muzvikamu zvemagetsi nemidziyo chaiyo.

Zvichakadaro, muindasitiri ye electroplating, sodium mercaptobenzothiazole inogona kushandiswa sechinhu chinogadzirisa zvinhu uye chinhu chinoenzanisa zvinhu. Kushandiswa kwe sodium mercaptobenzothiazole kunogona kugadzira zvinhu zvakagadzikana zvine ma ions esimbi mumushonga we electroplating, kudzora mwero wekuisa ma ions esimbi, kuita kuti coating ive yakafanana, yakakora uye yakajeka, kunatsiridza chitarisiko uye kunamira kwezvigadzirwa zve electroplated, uye zvakakodzera kune akasiyana maitiro e electroplating akadai se electroplating yekushongedza uye electroplating inoshanda.

III. Kurapa Mvura - Mushonga weChelating weMetal Ion Unoshanda Zvakanyanya

Mubasa rekuchenesa mvura mumaindasitiri, sodium mercaptobenzothiazole imushonga unoshanda wekubvisa maion esimbi, unonyanya kushandiswa kurapa mvura yakasviba yemaindasitiri ine maion esimbi anorema. Mvura yakasviba inoburitswa mumaindasitiri (yakadai se electroplating, metallurgy, chemical engineering nedzimwe nzvimbo) inowanzova nemaion esimbi anorema akadai se copper, lead, mercury ne cadmium. Maion aya ane chepfu yakawanda, kuoma kwekuora uye nyore kuungana, zvichikonzera njodzi huru kunharaunda nehutano hwevanhu.

Sodium mercaptobenzothiazoleinogona kusangana nemaitiro e chelation nema heavy metal ions mumvura yakasviba, zvichiita kuti chelate precipitates isanyungudike. Kuburikidza nekusefa, kusefa nedzimwe nzira, ma heavy metal ions anogona kubviswa mumvura yakasviba, zvichizadzisa chinangwa chekuchenesa mvura yakasviba. Kana ichienzaniswa nemidziyo yekubvisa simbi yakare, ine zvakanakira zvakaita sekugona kwayo kucheneswa, kukurumidza kuita nekukurumidza, uye pH range inoshanda. Sodium Mercaptobenzothiazole SMBT inogona kubvisa ma heavy metal ions nemazvo pasi pe pH range. Mvura yakasviba yakarapwa inogona kusangana nezvinodiwa nenyika. Panguva iyi, chelate mushure mekunaya kwemvura yakadzikama uye hainyanyi kunyungudika uye kukonzera kusvibiswa kwechipiri. Ndiyo imwe yemakemikari akakodzera ekurapa simbi yakaremara mumvura yakasviba yeindasitiri.

IV. Zvinoshandiswa pakurapa mishonga nemakemikari akanaka

Mundima yemishonga nemakemikari, sodium mercaptobenzothiazole inogona kushandiswa sechinhu chakakosha chekugadzira mishonga yakasiyana-siyana inoshanda muzvinhu zvipenyu. Mhete dzethiol nethiazole muchimiro chadzo chemamorekuru mapoka akakosha emabasa emamorekuru akawanda emishonga. Kuburikidza nekuwedzera kumwe, kuwedzera uye mamwe maitiro, mishonga yakasiyana-siyana yakadai semishonga inorwisa mabhakitiriya, mishonga inorwisa kuzvimba uye mishonga inorwisa bundu inogona kugadzirwa, zvichipa zvinhu zvekutanga zvekutsvagisa mishonga nekugadzira nekugadzira.

Pamusoro pezvo, mune mamwe makemikari akanaka, sodium mercaptobenzothiazole inogonawo kushandiswa kugadzira madhayi, pigments, zvinonhuwira nezvimwe zvigadzirwa. Nekushanda kwayo kwakasiyana kwemakemikari, sodium mercaptobenzothiazole inobatsira pakugadzirisa mashandiro ezvigadzirwa izvi uye inowedzera kushandiswa kwayo.

V. Nzira dzekudzivirira pakushandisa

Kunyange hazvo sodium mercaptobenzothiazole iine mashandisirwo akasiyana-siyana, matanho ekuchengetedza anofanira kutorwa panguva yekushandiswa kwayo. Sodium Mercaptobenzothiazole SMBT ine mwero wekutsamwa. Vashandi vanofanirwa kupfeka michina yekudzivirira (yakadai semasiki, magirovhosi, masutu ekudzivirira, nezvimwewo) kudzivirira kusangana zvakananga neganda nenzira yekufema. Painochengetwa, inofanira kuvharwa uye kuchengetwa munzvimbo yakaoma, ine mhepo inotonhorera uye inotonhorera, kure nezvinotsva, maoxidative nezvinhu zvine acidic kudzivirira kuora kana makemikari. Panguva imwe chete, munzvimbo dzakasiyana dzekushandisa, chiyero uye mamiriro ekushandiswa zvinofanirwa kudzorwa zvichienderana nezvinodiwa zvemaitiro chaiwo kuti ive nechokwadi chekuti kushandiswa kwacho kwakachengeteka.

Mukupedzisa,sodium mercaptobenzothiazole (CAS 2492-26-4)yakaratidza kukosha kukuru mumabasa akasiyana-siyana akadai seindasitiri yerabha, kugadzira simbi, kurapwa kwemvura, uye maindasitiri emishonga nemakemikari nekuda kwehunhu hwayo hwemakemikari hwakasiyana. Nekukura kuri kuramba kuchiita indasitiri yemakemikari akanaka, nzvimbo dzayo dzekushandisa dzichawedzerwa uye SMBT ichaita basa rakakosha mukugadzirwa kwemaindasitiri nekuchengetedzwa kwezvakatipoteredza.
