Sodium metabisulfite ipfu yekristalo chena kana yeyero kana kristaro diki ine hwema hwakasimba hweSO2. Mvura yayo ine acid uye inoburitsa SO2 kana yasangana neacids dzakasimba, zvichigadzira munyu wakafanana. Kana ikasiyiwa mumhepo kwenguva yakareba, inoshanduka kuita Na2S2O6, saka chigadzirwa ichi hachigone kuchengetwa kwenguva yakareba.
Kushandiswa
Inoshandiswa sezvinhu zvinochengetedza, zvinobvisa tsvina, uye zvinosunungura mukugadzira chikafu. Sodium metabisulfite inoshandiswa mumaindasitiri akadai sekudhinda nekudhaya, kugadzira organic, kudhinda, kugadzira dehwe, mishonga, nezvimwewo; Sodium metabisulfite inoshandiswa mumaindasitiri emakemikoro nemishonga mukugadzira hupfu hweinishuwarenzi, sulfamethoxazole metamaterial, caprolactam, pamwe nekuchenesa chloroform, phenylpropanoid sulfone, uye benzaldehyde. Inoshandiswa sechinhu chinogadzirisa muindasitiri yemifananidzo. Indasitiri yezvinonhuwira inoshandiswa kugadzira vanillin. Inoshandiswa sechinochengetedza muindasitiri yekubika doro, chinovhara rabha, uye chinobvisa chlorination yemicheka yedonje yakacheneswa. Organic intermediates, dyes, dehwe rinoshandiswa sechinoderedza tsvina, rinoshandiswa muindasitiri ye electroplating, kurapwa kwemvura yakasviba muminda yemafuta, uye rinoshandiswa sechinogadzirisa zvicherwa mumigodhi.
Kurongedza uye Kutumira
25KG/Drum kana zvichienderana nezvinodiwa nevatengi.
Ndezvezvinhu zvakajairika uye zvinogona kutumirwa negungwa nemhepo

Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
