Mashandisirwo uye Nheyo dzeSodium Hydrosulfide (NaHS)
Sodium hydrosulfide, ine fomura yemakemikari NaHS, chinhu chisina kugadzirwa uye sulfide inokosha. Imunyu unoumbwa ne sodium cations (Na⁺) uye hydrosulfide anions (HS⁻), inowanzoonekwa seupfu hwe crystalline chena muchimiro chayo chakasimba. Sodium hydrosulfide inonyungudika mumvura, ichigadzira mhinduro ye alkaline. Inoratidza kunyungudika kwakanaka uye kugadzikana, zvichiita kuti ishandiswe zvakanyanya mukugadzirwa kwemaindasitiri uye mukushandiswa kwemarabhoritari.
Sodium hydrosulfide inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, kunyanya munzvimbo dzinotevera:
2.1 Indasitiri yekugadzira simbi: Sodium hydrosulfide inoshanda semushonga wekugadzirisa pamusoro pesimbi. Inoshanda pamwe chete nesimbi kuti igadzire firimu re sulfide rinodzivirira, zvichidzivirira ngura zvinobudirira. Hunhu uhwu hunoita kuti ive yakakosha mukudzivirira ngura yesimbi, electroplating, uye mamwe maitiro akafanana.
2.2 Kugadzirwa kweOrganic: Mukugadzirwa kwezvinhu zvakasikwa, sodium hydrosulfide inoshanda sechinhu chinodzikisa. Inogona kuderedza mapoka anoshanda akadai sealdehydes nemaketones kune maalcohols anoenderana nawo, uye zvakare kuderedza makemikari ane mabhondi maviri kune maalcohols kana maamine.
2.3 Kugadzirira maSulfides: Senzvimbo inobva sarufa, sodium hydrosulfide inosangana nemaion esimbi kuti igadzire masulfide esimbi anoenderana nayo. Semuenzaniso, inosangana nemaion esimbi kuti igadzire sodium polysulfide, chinhu chakakosha che disulfide chinoshandiswa zvakanyanya sezvinhu zvisina kugadzirwa muhunyanzvi hwezvinhu zvakagadzirwa nekabhoni.
Muchikamu chekristaro chesodium hydrosulfide, maion esodium (Na⁺) nemaion ehydrosulfide (HS⁻) anobatanidzwa pamwe chete ne ionic bonds, chimiro chinotsigira hunhu hwayo hwemakemikari hwakasiyana.
3.1 Alkalinity: Kana yanyungudutswa mumvura, NaHS inopatsanurwa kuita maNa⁺ neHS⁻ ions. Iyo HS⁻ ioni ine alkaline, zvichiita kuti sodium hydrosulfide solution ive nyore uye inokwanisa kubvisa maasidhi.
3.2 Kuderedza Hunhu: Sodium hydrosulfide inoshanda semushonga unodzikisa simba nekupa maerekitironi kune zvinooxidating agents panguva yereactions. Mukugadzirwa kwezvinhu zvakasikwa, inoderedza maaldehydes, ketones, nemamwe mapoka anoshanda anogona kudzikiswa kuita maalcohols kana maamines.
3.3 Hunhu hweSulfidation: Yakaumbwa zvakanyanya nemaion e-hydrosulfide, sodium hydrosulfide inosangana nemaion esimbi kuti igadzire masulfide anoenderana. Masulfide aya ane hunhu hwakasiyana uye mashandisirwo awo akasiyana.
Sechinhu chakakosha chisina organic, sodium hydrosulfide inoshandiswa zvakanyanya mukugadzirisa simbi, kugadzira organic, uye kugadzira sulfide. Hunhu hwayo hwepakutanga - alkalinity, reducibility, uye sulfidation reactivity - inobvumira mhando dzakasiyana dzemakemikari uye mashandisirwo anoshanda. Kunzwisisa kwakakwana mashandisirwo ayo nemisimboti kwakakosha kuti iwedzere kushanda kwayo uye kushanda kwayo zvakanaka mukushandiswa kwemaindasitiri.
Sodium Hydrosulfide – Zibo Anhao Chemical Co., Ltd.
Zibo Anhao Chemical Co., Ltd. mutengesi akavimbika weSodium Hydrosulfide (NaHS), chinhu chakakosha chesulfide chisina kugadzirwa chine nhamba yeCAS 16721-80-5. Chigadzirwa chedu chinowanikwa mumhando dze solid flakes dzakachena (≥70% purity) uye mhinduro dzemvura dzakagadzikana (30%–45% concentration), dzakagadzirirwa kusangana nezvinodiwa nemaindasitiri zvakasiyana-siyana.
Yakagadzirwa pasi pemitemo yakasimba yekudzora mhando, sodium hydrosulfide yedu ine hunhu hwakagadzikana hwemakemikari, inonyunguduka zvakanyanya mumvura, uye ine alkaline solution yakasimba (pH 12–13). Inoshanda sechinhu chakakosha muzvikamu zvakasiyana: Migodhi & Metallurgy, Indasitiri yeDehwe, Dhayi & Makemikari, Kurapa Mvura Yakasviba, Fetereza & Fiber.
Nenzvimbo yakanaka muZibo, Shandong—nzvimbo huru yeindasitiri yemakemikari muChina—tinovimbisa kuti zvinhu zvinogadzirwa zvakanaka, mitengo inokwikwidzana, uye kurongedza kunochinjika (mabhegi e25kg, madhiramu e200kg). Sodium hydrosulfide yedu inoenderana nezvinodiwa zvepasi rose, ichipa mashandiro akafanana kune vatengi vepasi rose.
