China sodium formate wopanga, sodium formate ntchito ndi ntchito

China sodium formate wopanga, sodium mawonekedwe ntchito ndi ntchito,
opanga sodium formate m'nyumba, Hebei Pengfa sodium formate opanga, sodium formate zotsatira, Opanga sodium formate, othandizira amtundu wa sodium, Kugwiritsa ntchito sodium Formate, Kugwiritsidwa ntchito ndi mawonekedwe a sodium,
Physicochemical katundu:
1.White ufa: Kuthira madzi, kununkhira pang'ono kwa formic acid.
2. Malo osungunuka: 253 ℃
3.Kuchulukana kwachibale: 1.191g/cm3
4.Kusungunuka: Kusungunuka mu glycerin, kusungunuka pang'ono mu mowa, mowa, kusungunuka mu ether.

Storge
1.Sungani pamalo ozizira, owuma, opanda mpweya wabwino, pewani kuwala kwa dzuwa, kutali ndi kutentha, asidi, madzi, ndi mpweya wonyowa.
2.Kusindikiza dry preservation.Kumangirira ndi mapepala apulasitiki zilipo, ndi malaya woven thumba kulongedza.Monga mmene ambiri mankhwala kusungirako ndi mayendedwe.

Kufotokozera za khalidwe

Gwiritsani ntchito
1. Amagwiritsidwa ntchito m'makampani achikopa, monga kufufuta zikopa, chothandizira, chowongolera chogwiritsidwa ntchito ngati mchere wobisala munjira yowotchera chrome.
2.Gwiritsani ntchito muzothandizira ndi zokhazikika
3. Gwiritsani ntchito utoto wa nsalu ngati chochepetsera.
4. Ntchito mu zopangira kupanga sodium hydrosul-phite, formic acid ndi asidi oxalic
5. Amagwiritsidwa ntchito ngati anti-frosting wothandizira mu konkire
6. mpweya wamtengo wapatali
7. Monga buffer action , kusintha mtengo wa PHin amphamvu asidi

Zomwe zimagwiritsidwa ntchito kwambiri ndi izi:
(1) Amagwiritsidwa ntchito makamaka popanga formic acid, oxalic acid ndi ufa wa inshuwaransi, amagwiritsidwanso ntchito popanga dimethylformamide, etc. Amagwiritsidwanso ntchito pazamankhwala, kusindikiza ndi utoto.;
(2) reagents, mankhwala ophera tizilombo ndi mordant kudziwa phosphorous ndi arsenic;

(3) Amagwiritsidwa ntchito ngati chosungira.Gwiritsani ntchito zinayi: zokutira alkyd utomoni, plasticizer, wamphamvu;(4) Amagwiritsidwa ntchito ngati zophulika, zinthu zosagwira asidi, mafuta opaka ndege, zomatira.Sodium formate kupanga njira (1) Mmene mpweya monoxide ndi sodium hydroxide njira pa 160 ~ 200 ℃ ndi 2MPa kuthamanga kubala sodium formate, ndiyeno mwa sulfuric asidi hydrolysis, distillation kupeza yomalizidwa formic acid.Equation yayikulu ndi: CO+NaOH→HCOONA2HCOONa + H2SO4→ 2HCOOH + Na2SO4 (2) kupanga zotulutsa za neopentylene glycol, pentaerythritol ndi trimethylol propane.
