High Pure Sodium Fluorosilicate | Kupanga Mankhwala Otsuka Madzi

Sodium fluorosilicate imawoneka ngati kristalo woyera, ufa wa kristalo, kapena makhiristo a hexagonal opanda mtundu. Ndi yopanda fungo komanso kukoma. Kuchuluka kwake ndi 2.68; imatha kuyamwa chinyezi. Imatha kusungunuka mu chosungunulira monga ethyl ether koma sisungunuka mu mowa. Kusungunuka mu asidi ndi kwabwino kwambiri kuposa komwe kumakhala m'madzi. Imatha kuwola mu yankho la alkaline, ndikupanga sodium fluoride ndi silica. Ikapsa (300 ℃), imawola kukhala sodium fluoride ndi silicon tetrafluoride.

Makhalidwe Oyaka ndi Oopsa

Sizimayaka chifukwa zimatulutsa fluoride woopsa ndi sodium oxide, utsi wa silica; zikaphatikizidwa ndi asidi, zimatha kupanga hydrogen fluoride woopsa.

Makhalidwe Osungira

Chuma:mpweya wabwino, kutentha kochepa, ndi kuumitsa; sungani padera pa chakudya ndi asidi.

Kuopsa kwa poizoni

Mankhwalawa ndi oopsa ndipo amakhudza ziwalo zopumira. Anthu omwe amwa mankhwala ophera mkamwa molakwika amakhala ndi zizindikiro zazikulu za kuwonongeka kwa matumbo ndipo mlingo wakupha ndi 0.4 ~ 4g. Pamene wogwiritsa ntchitoyo akugwira ntchito, ayenera kuvala zida zodzitetezera kuti asaphedwe. Zipangizo zopangira ziyenera kutsekedwa ndipo malo ogwirira ntchito ayenera kukhala ndi mpweya wabwino.

Kuchiza Madzi Sodium Silicofluoride, Sodium Fluorosilicate, SSF, Na2SiF6.

Sodium fluorosilicate ikhoza kutchedwa sodium silicofluoride, kapena sodium hexafluorosilicate, SSF. Mtengo wa sodium fluorosilicate ukhoza kutengera kuchuluka kwa chinthu, komanso kuyera komwe wogula amafunikira.

    • 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.
