Ntchito ndi ndondomeko chitukuko cha sodium formaldehyde sulfoxylate

Sodium sulfoxylate formaldehyde (NaHSO2 · CH2O · 2H2O),

Amadziwikanso kuti assodium formaldehyde sulfoxylate,

Dzina lazinthu: Rongalite C.

Ndi chipika choyera chowoneka bwino chokhala ndi malo osungunuka a 64 ℃. Imakhala ndi reducibility yamphamvu pa kutentha kwambiri ndipo imatha kuzimiririka nsalu zotayidwa.

Chifukwa chake, amagwiritsidwa ntchito kwambiri ngati chotulutsa mumakampani osindikizira ndi utoto, monga chopangira bleaching mu kaphatikizidwe ka mphira ndi mafakitale a shuga.

Ndi chitukuko ndi kugwiritsa ntchito zinthu, m'zaka zaposachedwa, zakhala zikugwiritsidwa ntchito m'makampani a sopo komanso chithandizo chamankhwala ngati mankhwala a Hg, Bi, Ba.

Kupanga rarongalite nthawi zambiri kumagwiritsa ntchito njira yanthawi zitatu, njira ya zinc powder-sulfur dioxide-formaldehyde.

Ndiko kuti, sulfure dioxide, nthaka ufa, ndi formaldehyde amagwiritsidwa ntchito ngati zopangira, ndipo sulfure dioxide ndi nthaka ufa amachitira kupanga zinki dithionite (ZnS2O4), ndiyeno formaldehyde Kuwonjezera, zinki ufa kuchepetsa ndi sodium hydroxide metathesis anachita kupanga mankhwala.

Kupanga kwa domesticrongalite kumagwiritsanso ntchito zaluso zomwe tazitchula pamwambapa. Zogulitsazo zimaperekedwa makamaka kumsika wapanyumba, ndipo zina zimatumizidwa ku Southeast Asia.

Zomwe timayambitsa ndi njira yatsopano , ndiko kuti, njira yopezera mankhwala kuchokera ku sodium metabisulfite monga zopangira mwa kuchepetsa ufa wa zinc ndi kuwonjezera kwa formaldehyde mu sitepe imodzi.

Zopangirazo zimachepetsedwa ndikuwonjezeredwa mu ketulo yomweyo, ndipo zonse zomwe zimapangidwira zimasinthidwa kukhala zinthu, ndipo palibe zowonongeka.

Kuphatikiza pa zinthu zazikuluzikulu, imapanganso zinthu zoyera za zinc oxide (99.5%).

ndondomeko ali ndi makhalidwe a ndondomeko yochepa, zinthu khola luso, otsika zida ndalama ndi ntchito yosavuta.

M'nkhani yotsatira, ndigawana nawo njira yopangira sodium formaldehyde sulfoxylate.
