Sodium metabisulphite (Na2S2O5) icrystalline poda isina ruvara inoshandiswa zvakanyanya mukudya, zvekuzora, mushonga uye machira mumunda, uye yakakosha sulfite komputa.Inoumbwa neayoni maviri sulfnyl uye maviri sodium ions.Pasi pemamiriro eacidic, sodium metabisulphite inoora kuita sarufa dhiokisi, mvura uye sulphite, saka inoshandiswa zvakanyanya mukugadzira chikafu uye chinwiwa indasitiri, ichitamba disinfection, sterilization uye antioxidant basa.
1. Chimiro chemakemikari uye maitiro e sodium metabisulphite
Sodium metabisulphite ine zvakakosha zvemuviri nemakemikari zvimiro, mamorekuru ayo formula ndeye Na2S2O5, chiyero chemolecular mass i190.09 g/mol, density i2.63 g/cm³, panonyungudika i150 ℃, panofashaira ingangoita 333 ℃.Sodium metabisulphite ikristaro isina ruvara inonyungudika nyore mumvura uye glycerol, yakagadzikana mualkaline mhinduro, uye inoora zviri nyore kuita sulfur dioxide uye sulfite ions pasi pemamiriro ane acidic.Sodium metabisulphite yakagadzikana mumhepo yakaoma, asi inoputsika mumhepo ine hunyoro kana pakupisa kwakanyanya.
2. Munda wekushandisa we sodium metabisulphite
Sodium metabisulphite inoshandiswa zvakanyanya mukuwedzera kwechikafu, inoshandiswa muzvigadzirwa zvenyama, zvigadzirwa zvemumvura, zvinwiwa, zvinwiwa zvemalt, soy muto uye zvimwe zvekudya se antioxidant, preservative uye bleach.Inogona zvakare kushandiswa kugadzira zvinotapira zvakadai semasiwiti, magaba, jamu uye zvinochengetedza kusimudzira hupenyu hwavo hwesherufu uye kuravira.Sodium metabisulphite inogona zvakare kushandiswa sechinhu chinokonzeresa muindasitiri yemafuta, bleaching agent muindasitiri yemapepa, mishonga yekuwedzera, uye makemikari ekuwedzera mudhayi uye machira maitiro.
3. Mechanism yekuita sodium metabisulphite
Basa guru re sodium metabisulphite sechikafu chekuwedzera senge antioxidant uye kuchengetedza.Inogona kunyatso kuvharidzira oxidation yemafuta muchikafu, inonoke kuderera kwechikafu, uye nekudaro inowedzera hupenyu hwesherufu yekudya.Panguva imwecheteyo, sodium metabisulphite inogonawo kudzivisa kukura kwebhakitiriya uye mold muzvokudya uye kudzivisa kusvibiswa kwezvokudya nema microorganisms.Iyi antioxidant uye antibacterial effect inowanikwa ne sulfur dioxide uye sulfite ions inogadzirwa nekuparara kwe sodium metabisulphite.
Pamusoro pekushandiswa kwayo muindasitiri yekugadzira chikafu, sodium metabisulphite inogonawo kushandiswa sekemikari mune mamwe minda, senge mafuta anokonzeresa, bleach agents, mishonga additives, etc. Muzvikumbiro izvi, maitiro ekuita uye maitiro ekushandisa sodium metabisulphite. zvakare akasiyana, asi ese ane hukama neayo antioxidant, antiseptic, bactericidal uye bleaching properties.
4.Kuchengetedzwa uye kukanganisa kwezvakatipoteredza kwe sodium metabisulphite
Sodium metabisulphite ikemikari inoshandiswa zvakanyanya, uye kukanganisa kwayo pahutano hwevanhu nekuchengetedzeka kwezvakatipoteredza kwakwezva kutarisisa kwakawanda.Kazhinji, sodium metabisulphite yakachengeteka kushandisa mukati meiyo yakatarwa dosage renji.Zvisinei, kana kushandiswa kwakanyanyisa uye kwenguva yakareba kuratidzwa kwehuwandu hwe sodium metabisulphite inogona kuva nemigumisiro pahutano hwevanhu, zvakadai sekuputika kweganda, kuoma kwekufema, allergies, etc. Mukuwedzera, sodium metabisulphite mukuora kwekugadzira sulfur dioxide. inogonawo kugadzira SOx (sulfur oxides) nezvimwe zvinosvibisa, zvichikonzera kumwe kukanganisa kwakatipoteredza.Naizvozvo, kana uchishandisa sodium metabisulphite, kutonga uye kuchengetedzwa kunofanirwa kuitwa kudzivirira njodzi dzinogona kuitika uye kukanganisa kwezvakatipoteredza.
Muchidimbu, sodium metabisulphite ikemikari inoshandiswa zvakanyanya, inova yakakosha kemikari yakabikwa mukugadzira chikafu, zvekuzora, mushonga uye machira.Iine zvinhu zvakawanda zvinoshanda senge anti-oxidation, anti-corrosion, sterilization, bleaching uye zvichingodaro, uye ikemikari yakakosha muminda yakawanda.Nekudaro, mukuita kwekushandisa, zvichiri kudikanwa kutarisisa nyaya dzekuchengetedza uye kuchengetedza kwezvakatipoteredza kuti upe kutamba kwakazara kune yayo yakanaka mhedzisiro uye kudzivirira mhedzisiro yakaipa pahutano hwevanhu uye nharaunda.
Isu Weifang Totpion Chemical Indasitiri Co., Ltd ndivo nyanzvi inopa sodium metabisulphite.Ndokumbira ushanyire webhusaiti yedu www.toptionchem.com kuti uwane rumwe ruzivo.Kana uine chero chinodiwa, ndapota usazeza kutibata nesu.
