Kugwiritsa Ntchito Sodium Sulphite 

Gawo la mafakitale Sodium sulfite ingagwiritsidwe ntchito ngati chothandizira kuchiza madzi, choletsa dzimbiri, chothandizira kuchiza pamwamba pa chitsulo, cholimbikitsira kuuma kwa simenti, chothandizira kufalitsa ma pulp paper copper plate ndi kuboola mafuta, ndi zina zotero; sodium sulfite ya kalasi ya chakudya imagwiritsidwa ntchito makamaka ngati chowonjezera khalidwe, chothandizira kuchetsa, chothandizira kuwiritsa, chothandizira kusintha pH, ndi zina zotero.

Rongda Chemical yotsatirayi ikukupatsani kumvetsetsa mwatsatanetsatane kagwiritsidwe ntchito ndi ntchito za sodium sulfite.

Ntchito 1: Imagwiritsidwa ntchito pofufuza kusanthula kwa tellurium ndi niobium komanso kukonzekera yankho lopanga, lomwe limagwiritsidwanso ntchito ngati chochepetsera.

Ntchito 2: Yopangira ulusi wokhazikika, wothandizira kuyeretsa nsalu, wopanga zithunzi, wopaka utoto ndi kuyeretsa deoxidizer, wochepetsa fungo ndi utoto, wochotsa lignin ya pepala, ndi zina zotero.

Ntchito 3: Imagwiritsidwa ntchito ngati reagent yowunikira komanso zinthu zoteteza kuwala.

Kugwiritsa Ntchito 4: Chotsukira madzi chochepetsa kukhuthala, kukhuthala kwa chakudya komanso kuletsa kwambiri oxidase muzakudya za zomera. China ikunena kuti ingagwiritsidwe ntchito posungira pamlingo wapamwamba kwambiri wa 2.0g/kg; ingagwiritsidwenso ntchito mu shuga, shuga wamadzimadzi, shuga wa patebulo, shuga wa m'mwala, caramel, makeke, mphukira za nsungwi, bowa wokazinga ndi bowa, mphesa, madzi a blackcurrant omwe amagwiritsidwa ntchito pamlingo wapamwamba kwambiri wa 0.60g/kg. zotsalira za mphukira za nsungwi, bowa wokazinga ndi bowa, zosungira, mphesa ndi madzi a blackcurrant omwe amagwiritsidwa ntchito (mu SO2) ≤ 0.05g/kg. Zotsalira za wowuma wa mbatata ≤ 0.03g/kg; zotsalira za mabisiketi, shuga, vermicelli ndi mitundu ina yosakwana 0.1g/kg; zotsalira za shuga wamadzimadzi zisapitirire 0.2g/kg.

Kugwiritsa Ntchito 5: Amagwiritsidwa ntchito mumakampani osindikiza ndi kupaka utoto ngati choyeretsera ndi choyeretsera, chomwe chimagwiritsidwa ntchito pophika nsalu zosiyanasiyana za thonje, chimatha kuletsa kukhuthala kwa ulusi wa thonje ndikukhudza mphamvu ya ulusi, ndikuwonjezera kuyera kwa zinthu zophikira. Makampani ojambula zithunzi ngati choyeretsera. Amagwiritsidwa ntchito ngati chochepetsera kupanga m-phenylenediamine, 2,5-dichloropyrazolone, anthraquinone-1-sulfonic acid, 1-amino anthraquinone, sodium aminosalicylate, ndi zina zotero. Amatha kuletsa kukhuthala kwa zinthu zomwe zatha pang'onopang'ono panthawi yochitapo kanthu. Amagwiritsidwa ntchito mumakampani opanga mapepala ngati chochotsera lignin. Makampani opanga nsalu amagwiritsa ntchito ngati chokhazikika cha ulusi wopangidwa ndi anthu. Makampani opanga zamagetsi amagwiritsidwa ntchito popanga zotsutsana ndi zithunzi.

Makampani okonza madzi amagwiritsidwa ntchito pokonza madzi otayira ndi madzi akumwa pogwiritsa ntchito ma electroplating.

Ntchito 6: Imagwiritsidwa ntchito ngati choyeretsera, chosungira, chotsitsimula komanso choteteza ku matenda obwera chifukwa cha mankhwala m'makampani azakudya. Imagwiritsidwanso ntchito popanga mankhwala. Imagwiritsidwa ntchito ngati chochepetsera kupanga ndiwo zamasamba zopanda madzi.

Ntchito 7: Imagwiritsidwa ntchito popanga ester ya cellulose sulfite,sodium thiosulfate,mankhwala achilengedwe, nsalu yoyeretsa, ndi zina zotero. Imagwiritsidwanso ntchito ngati chochepetsera, chosungira, chochotsera chlorine, ndi zina zotero.

Tili ndi zinthu zina zambiri zopangira mankhwala, mwachitsanzo,sodium sulfite anhydrous，zinc sulphate，zinc oxide，ndi zina zotero. Ngati mukufuna kulankhulana ndi wopanga
