Chaw tsim tshuaj paus Zoo Nqe Ammonium Bifluoride CAS: 1341-49-7

piav qhia luv luv:

Ammonium hydrogen fluoride tseem hu ua acid ammonium fluoride.Cov tshuaj formula NH4F HF.Molecular hnyav 57.04.Dawb deliquous hexagonal siv lead ua, tshuaj lom.Nws yog ib qho yooj yim rau delix.Tus txheeb ze ntom ntom yog 1.50, lub melting point yog 125.6 ℃, thiab refraction yog 1.390.Muaj peev xwm sublimate, corrosive rau iav, kub lossis dej kub yuav decompose.Soluble hauv dej, me ntsis soluble hauv cawv.Aqueous tov yog acidic, tuaj yeem corrode iav Chemicalbook iav, corrosive rau ntawm daim tawv nqaij.Gaseous ammonia tau ntxiv rau 40% ntawm hydrofluoric acid, ces txias thiab crystallized.

Txoj kev npaj: 1 mole ntawm ammonia dej kom nqus 2 moles ntawm hydrogen fluoride, thiab ces txias, concentration, crystallization.

Siv: Siv ua tshuaj reagent, earthenware thiab iav etching, electroplating, brewing kev lag luam, fermentation kev lag luam preservative thiab kab mob inhibitor, thiab lwm yam. Nws kuj yog siv nyob rau hauv beryllium smelting thiab ceramic manufacturing.

Chemical Properties： Dawb los yog tsis muaj xim pob tshab rhombic siv lead ua siv lead ua, cov khoom yog flake, me ntsis qaub saj.Me ntsis soluble hauv cawv, yooj yim soluble hauv dej txias, decomposition hauv dej kub.Dej yog acidic heev thaum yaj.

Kev siv Ammonium Bifluoride

1. Cov tshuaj kho deg rau iav etching, tshuaj tua kab mob, tshuaj tua kab mob, hlau cymbals, thiab silicon steel daim hlau kuj tseem siv los ua cov ceramics thiab magnesium alloys.

2. Nws tuaj yeem siv los ua cov tshuaj reagents, iav etching (feem ntau ua ke nrog hydrofluoric acid), fermented industrial disinfection agents thiab preservatives, cov kuab tshuaj uas oxidized, thiab cov tshuaj kho deg ntawm silicon steel daim hlau.ChemicalBook kuj tseem siv los ua cov ceramics thiab magnesium alloys, boilers los ntxuav cov dej thiab chav dej, thiab acidification ntawm cov roj av xuab zeb.Nws kuj yog siv los ua alkylated thiab heterogeneous catalyst Cheebtsam.

3. Rau cov roj teb acidification kev kho mob, tsim khoom ntawm magnesium thiab magnesium alloys.Rau lub teeb ntawm iav, qab zib, etching tus neeg saib xyuas, siv los ua cov tshuaj tiv thaiv ntoo, aluminium optical agents, textile industries yog siv los ua cov tshuaj tshem tawm xeb, thiab tseem tuaj yeem siv rau electroplating, electronics kev lag luam, raws li kev tshuaj ntsuam reagent.

4. Siv los ua cov tshuaj analytical reagents thiab cov kab mob inhibitors.

5. Kev tshuaj ntsuam reagent.Siv rau ceramic thiab iav nto.Tshuaj tua kab mob.Kev npaj ntawm hydrogen fluoride hauv chav kuaj.plating.
