Sodium hydrosulfite

Sodium hydrosulfite ndi mankhwala ochepetsera utoto omwe amagwiritsidwa ntchito kwambiri popaka utoto wa indigo. Ithanso kugwiritsidwa ntchito ngati njira ina yochepetsera utoto m'malo mwa bleach pochotsa utoto pa nsalu zopaka utoto komanso kupukuta nsalu zakale.

Nambala ya CAS：7775-14-6

Molecular Formula: Na₂S₂O₄

Katundu

Sodium hydrosulfite ili ndi mankhwala apadera. Siikhazikika kwambiri mumadzi ndipo imasungunuka mosavuta kukhala sodium sulfate, sodium sulfide, ndi sulfur dioxide. Chomerachi chili ndi kutentha kwa 300°C komanso kutentha kwa 1390°C, ndipo chimakhala chokhazikika bwino munyengo youma komanso yotentha pang'ono. Komabe, chimakhala chovuta kwambiri ndi chinyezi ndi mpweya, zomwe zimapangitsa kuti chiwole msanga.

Mapulogalamu

• Makampani Opanga Nsalu: Itha kugwiritsidwa ntchito ngati chochepetsera utoto, zomwe zimathandiza kuti mamolekyu a utoto alowe bwino mu nsalu. Imagwiranso ntchito ngati choyeretsera utoto cha thonje ndi silika, zomwe zimapangitsa kuti nsalu ziwoneke bwino komanso kuti zisamawonekere bwino.

• Makampani Opanga Mapepala: Sodium bisulfite ndiye chinthu choyeretsera khungu chomwe chimakonda kwambiri pamakina, thermomechanical pulp, ndi pulp yochotsedwa utoto, zomwe zimapangitsa kuti mapepala akhale oyera komanso abwino.

• Makampani Ogulitsa Chakudya: Monga chowonjezera pa chakudya, chimagwira ntchito ngati choyeretsera komanso choteteza ku ma antioxidants a zipatso zouma, ndiwo zamasamba zouma, Zakudya zophikidwa, ndi mphesa. Chimathandiza kusunga mtundu wa chakudya ndikuwonjezera nthawi yosungira chakudya.

• Uinjiniya Wachilengedwe: Pochiza madzi otayidwa, sodium metabisulfite imachepetsa zinthu zoopsa, zomwe zimathandiza kuti madzi oyera komanso otetezeka atuluke.

• Makampani Opanga Mankhwala: Amagwira ntchito ngati chochepetsera kupanga kwa thiourea ndi ma sulfide ake, ndipo amagwira ntchito yofunika kwambiri pazochitika zosiyanasiyana za mankhwala.

Kulongedza

Yopakidwa m'mabokosi achitsulo kapena matumba apulasitiki, okhala ndi zolemera zoyambira 15 mpaka 200 kg. Imapezeka m'mabokosi a 20/50 kg ndi matumba apulasitiki otsekedwa kawiri a 250 g.

Malo Osungirako

Sungani pamalo ouma, ozizira, komanso opumira bwino kutentha kwa pakati pa +5°C ndi +30°C. Kuti mupewe kukhudzana ndi mankhwala, pewani kukhudzana ndi asidi amphamvu, zinthu zowononga okosijeni, madzi, ndi chinyezi. Mukamagwira ufa, valani magolovesi, chigoba cha fumbi, ndi magalasi oteteza. Sungani mankhwalawa kutali ndi ana ndi ziweto.

Mayendedwe

Popeza mankhwalawa ndi osavuta kukhudzidwa ndi chinyezi ndi mpweya, zomwe zingayambitse kutulutsidwa kwa sulfur dioxide (SO₂), njira zoyenera zotetezera ziyenera kutengedwa panthawi yonyamula.

    • Kodi ndingasankhe bwanji mankhwala oyenera kugwiritsa ntchito?

    Mungathe kutiuza momwe ntchito yanu ikugwiritsidwira ntchito, monga mtundu wa dziwe losambira, mawonekedwe a madzi otayira m'mafakitale, kapena njira yoyeretsera yomwe ilipo panopa.

    Kapena, chonde perekani mtundu kapena chitsanzo cha chinthu chomwe mukugwiritsa ntchito panopa. Gulu lathu laukadaulo lidzakupangirani chinthu choyenera kwambiri kwa inu.

    Mungathenso kutitumizira zitsanzo kuti zikawunikidwe mu labotale, ndipo tidzapanga zinthu zofanana kapena zabwino malinga ndi zosowa zanu.

     

    Kodi mumapereka ntchito za OEM kapena zachinsinsi?

    Inde, timathandizira kusintha kwa zinthu polemba zilembo, kulongedza, kupanga, ndi zina zotero.

     

    Kodi zinthu zanu zili ndi satifiketi?

    Inde. Zogulitsa zathu zili ndi satifiketi ya NSF, REACH, BPR, ISO9001, ISO14001 ndi ISO45001. Tilinso ndi ma patent azinthu zopangidwa mdziko lonse ndipo timagwira ntchito ndi mafakitale ogwirizana nawo poyesa SGS ndikuwunika mpweya.

     

    Kodi mungatithandize kupanga zinthu zatsopano?

    Inde, gulu lathu laukadaulo lingathandize kupanga mafomula atsopano kapena kukonza zinthu zomwe zilipo kale.

     

    Kodi zimatenga nthawi yayitali bwanji kuti muyankhe mafunso?

    Yankhani mkati mwa maola 12 pa masiku ogwira ntchito, ndipo funsani kudzera pa WhatsApp/WeChat ngati mukufuna zinthu zofunika mwamsanga.

     

    Kodi mungapereke zambiri zonse zotumizira kunja?

    Ikhoza kupereka zambiri zonse monga invoice, mndandanda wa zonyamula katundu, bilu ya katundu, satifiketi yochokera, MSDS, COA, ndi zina zotero.

     

    Kodi ntchito yogulitsa pambuyo pa malonda imaphatikizapo chiyani?

    Perekani chithandizo chaukadaulo pambuyo pa malonda, kusamalira madandaulo, kutsatira njira zoyendera, kubwezeretsanso kapena kulipira mavuto aubwino, ndi zina zotero.

     

    Kodi mumapereka malangizo ogwiritsira ntchito mankhwala?

    Inde, kuphatikizapo malangizo ogwiritsira ntchito, chitsogozo cha mlingo, zida zophunzitsira zaukadaulo, ndi zina zotero.
