Maitiro ekudzokorodza Tungsten Carbide Zvishandiso

Tungsten carbide inozivikanwawo se tungsten alloy, simende carbide, hard alloy, uye hard metal. Tungsten carbide zvishandiso zvave kuwedzera mukurumbira muindasitiri yemazuva ano kubvira kuma1920s. Nezvakatipoteredza, kudzokororwa kwezvigadzirwa zve tungsten carbide zvinobuda izvo zvinogona kukonzera mutengo uye kutambisa simba. Panogona kuva nemaitiro emuviri kana nzira yemakemikari. Nzira yemuviri kazhinji ndeyekupwanya tungsten carbide zvishandiso zvakaraswa kuita zvidimbu, izvo zvakaoma kuziva uye zvinodhura zvakanyanya nekuda kwekuoma kukuru kwetungsten carbide zvishandiso. Saka, kudzokorodza tungsten carbide yekucheka maturusi anowanzo zivikanwa mumakemikari nzira. Uye nzira nhatu dzemakemikari dzichaunzwa---zinc kupora, electrolytic kupora, uye kudhirowa neoxidation.

Zinc Recovery

Zinc imhando yemakemikari element ine nhamba yeatomu 30, ine 419.5 ℃ inonyunguduka uye inofashaira inosvika 907 ℃. Mukuita kupora zinc, tungsten carbide yekucheka maturusi anoiswa muzinc yakanyungudutswa pasi penzvimbo ye650 kusvika 800 ℃ kutanga. Izvi zvinoitika neinert gasi muchoto chemagetsi. Mushure mekupora zinc, zinc ichave yakanyungudutswa pasi petembiricha ye700 kusvika 950 ℃. Somugumisiro wekupora zinc, hupfu hwakadzorerwa hunenge hwakafanana nehupfu hwemhandara muhuwandu.

Electrolytic Recovery

Mukuita uku, iyo cobalt binder inogona kunyungudika ne electrolyzing zvimedu zvetungsten carbide yekucheka maturusi kuti adzorere tungsten carbide. Nekupora kwe electrolytic, hakuzove nekusvibiswa mune yakadzoserwa tungsten carbide.

Kubviswa neOxidation

1. Tungsten carbide scrap inofanira kugayiwa nekusanganiswa neoxidizing agents kuti iwane sodium tungsten;

2. Sodium tungsten inogona kurapwa nemvura uye ruzivo kusefa uye kunaya kwemvura kubvisa tsvina kuti uwane yakacheneswa sodium tungsten;

3. Yakanatswa sodium tungsten inogona kugadziriswa ne reagent, iyo inogona kunyungudutswa mune organic solvent, kuwana tungsten mhando;

4. Wedzera aqueous ammonia solution uye wozobvisa zvakare, tinogona kuwana ammonium poly-tungstate solution;

5. Zviri nyore kuwana ammonium para-tungstate crystal ne evaporating iyo ammonium poly-tungstate mhinduro;

6. Ammonium para-tungstate inogona kuverengerwa uye yozoderedzwa nehydrogen kuti iwane tungsten simbi;

7. Mushure mekuviga tungsten simbi, tinogona kuwana tungsten carbide, iyo inogona kugadzirwa mune zvakasiyana tungsten carbide zvigadzirwa.

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
