Potassium Humate Action

Lub luag haujlwm ntawm potassium hydroxide:

1. Kev lag luam inorganic yog siv los ua poov tshuaj, xws li potassium permanganate, potassium nitrite, dipotassium phosphate, thiab lwm yam.

2. Kev lag luam txhua hnub yog siv cov khoom siv los ua cov tshuaj ntxuav tais diav, ntxuav tes, xab npum, da dej qab zib, txias qab zib, zawv plaub hau thiab lwm yam. Kev lag luam kws tshuaj siv los ua raw khoom xws li progesterone thiab vanillin.

3. Kev lag luam yog siv los ua melamine dyes

4. Kev lag luam roj teeb siv los ua kua roj alkaline. [4] siv los ua ib qho kev noj qab haus huv, kua nqhuab, siv los ua kua ntsev, oxalic acid thiab ntau hom tshuaj kua qaub, thiab siv rau electroplating, engraving, lithography thiab lwm yam. Nws yog siv los ua raw khoom rau potash ntau lawm, xws li potassium permanganate thiab potassium carbonate.

5. Hauv kev lag luam hauv tshuab hluav taws xob, rau electroplating, engraving, thiab lwm yam. Nyob rau hauv lub lag luam textile, nws yog siv rau dyeing, tshuaj dawb thiab mercerizing, thiab nws yog siv los ua cov khoom tseem ceeb rau kev ua fibers thiab polyester fibers.

Cov kua tshuaj kua tshuaj carbon dioxide: potassium hydroxide (tshuaj: KOH, hom: 56.11) hmoov av los yog cov khoom nplaum. Melting point ntawm 360 ~ 406 ℃, taw tes rau ntawm 1320 ~ 1324 ℃, qhov sib npaug ntawm 2.044 g / cm, flash point 52 ° F, qhov kev ntsuas qis n20 / D1.421, vapor siab 1 MMHG (719 ℃). Nws yog alkaline heev thiab corrosive. Yooj yim kom nqus ya raws huab cua thiab noo noo, nqus carbon dioxide thiab ua poov tshuaj carbonate. Tshaj li ntawm 0.6 feem ntau ntawm cov dej kub, 0.9 hauv dej txias, 3 ethanol, thiab 2.5 glycerin. Thaum yaj hauv dej, dej cawv, lossis kho cov kua qaub, ntau ntau cov cua kub.

Kev ua haujlwm: siv tshuaj ua lag luam yog siv los ua poov tshuaj, xws li potassium permanganate, potassium nitrite, dipotassium phosphate, thiab lwm yam. Kev lag luam niaj hnub siv los ua cov khoom siv ua kua ntoo, xab npum, xab npum, da dej, tsuaj zawv plaub hau thiab lwm yam. Kev lag luam kws tshuaj siv los ua raw khoom xws li progesterone thiab vanillin. Dye kev lag luam yog siv los ua melamine dyes. Lub roj teeb kev lag luam yog siv los ua cov roj av alkaline.

Daim teb daim ntawv thov

1. Siv ua ib qho kev haus luam yeeb thiab nqus dej, siv los ua cov oxalic acid thiab ntau hom tshuaj kua roj, thiab siv rau electroplating, engraving, litithography etc

2. Feem ntau yog siv raw khoom rau cov kua qoob loo, xws li potassium permanganate thiab potassium carbonate. Nyob rau hauv kev lag luam kev lag luam, nws yog siv los tsim cov kua qaub haum roj, cov tshuaj antibody, salicylic acid, propionate, thiab lwm yam. Siv hauv kev lag luam uas tsim los tsim cov kua tshuaj ntxuav tes, kua roj (alkaline), cov tshuaj pleev ib ce (xws li txias qab zib, cream thiab tsuaj zawv plaub hau). Hauv kev lag luam xim, nws yog siv los tsim VAT dyes, xws li txo qhov xiav pob zeb RSN. Hauv kev lag luam electrochemical, rau electroplating, engraving, thiab lwm yam. Nyob rau hauv lub lag luam textile, nws yog siv rau dyeing, tshuaj dawb thiab mercerizing, thiab nws yog siv los ua lub ntsiab raw khoom ua cov txiv neej ua fibres thiab polyester fibers. Tsis tas li ntawd, nws yog siv nyob rau hauv metallurgical cua sov tus neeg sawv cev thiab tawv degreasing.

3. Cov khoom siv tshuaj raw cov ntaub ntawv pov thawj rau tshuaj thiab niaj hnub kev lag luam.

4. Siv ua cov tshuaj ntxaum rau cov tshuaj reagents, cov kua zeb khib nyiab, carbon dioxide thiab dej.

5. Kev lag luam txhua hnub yog siv raw li ntxuav thiab ntxuav cov tshuaj ntxuav tes, xab npum ntxuav muag, da dej qab zib, txias qab zib, zawv plaub hau thiab lwm yam. Kev lag luam kws tshuaj siv los ua raw khoom xws li progesterone thiab vanillin. Dye kev lag luam yog siv los ua melamine dyes. Lub roj teeb kev lag luam yog siv los ua cov roj teeb alkaline

Txheeb xyuas cov ntsiab lus

Hais tau tias qhov qauv piv txwv txog 1.5 g, soluble hauv 40 ml tshiab dej kub thiab txias, txias rau 15 ℃, nrog cov tshuaj phenolphthalein (TS - 167) ntau ntau, nrog 1 mol / L acid titration. Thaum paj liab ploj, sau cov kua qaub qaub, ntxiv cov tshuaj methyl txiv kab ntxwv tshuaj (TS-148), thiab ntxiv titration kom txog thaum lub paj liab tas li. Sau tag nrho ntim ntawm cov kua qaub uas yuav tsum tau ua rau titration. Txhua Ml ntawm 1mol / L ntawm sulfuric acid yog sib npaug rau 56.11mg ntawm tag nrho cov alkalinity (KOH).
