Chaw tsim tshuaj paus zoo li tus nqi ammonium bifluoride: 1341-49-7 Featured Duab

Cov lus piav qhia luv luv:

Ammonium hydrogen fluoride tseem muaj lub npe hu ua acid ammonium fluoride. Tshuaj mis mis nh4f hf. Molecular hnyav 57.04. Dawb dhuav tsis ncaj hexagonalrystal, lom. Nws yog ib qho yooj yim rau delix. Cov txheeb ze ceev yog 1.50, lub taw tes melting yog 125.6 ℃, thiab qhov refraction yog 1.390. Tuaj yeem sublimate, corrosive rau iav, kub lossis dej kub yuav decompose. Soluble hauv dej, me ntsis soluble hauv cawv. Cov kua roj afous yog muaj zog acidic, tuaj yeem corrode iav spreadbook cov iav, corrosive rau daim tawv nqaij. Gonoous ammonia tau ntxiv rau 40% ntawm cov kua txiv hydrofluoric, tom qab ntawd txias thiab crystallized.

Kev npaj txoj kev: 1 mole ntawm ammonia dej kom nqus 2 moles ntawm hydrogen fluoride, thiab tom qab ntawd txias, conystallization.

Siv: siv los ua tshuaj reagent, earthenware thiab iav etching, fermentation kev lag luam txuag hluav taws xob txuag hluav taws xob txuag hluav taws xob txuag hluav taws xob thiab lwm yam.

Tshuaj Tshuaj Muaj Zog: Dawb dawb lossis tsis muaj pob tshab rhombic crystal system crystal, cov khoom yog flake, me ntsis qaub saj. Soluble me ntsis hauv cawv, yooj yim soluble hauv dej txias, decomposition nyob rau hauv dej kub. Dej yog muaj zog acidic thaum yaj.

Cov ntawv thov ntawm ammonium bifluide

1. Cov tshuaj tiv thaiv kom huv rau cov iav etching, tshuaj tua kab mob, cov hlau nplaum hlau kuj tseem siv los ua ceramics thiab cov khoom siv hlau nplaum.

2. Yuav siv tau los ua tshuaj lom neeg cov tshuaj lom zem, cov iav etching (feem ntau ua ke nrog cov tshuaj tua kab mob hydrofrectic thiab cov tshuaj lom neeg muaj cov kab mob, thiab cov neeg sawv cev kom sawv cev ntawm cov thawv Silicon. Cov tshuaj lom neeg tseem siv los ua ceramics thiab magnesium alloys, boilers los ntxuav cov dej system thiab chav dej, thiab cov acidification ntawm cov roj av roj. Nws tseem siv raws li alkylated thiab heterogeneous catalysst Cheebtsam.

3. Rau roj ua teb acidification, tsim cov khoom siv ntawm cov magnesium thiab maglots. Rau lub teeb ntawm iav, cream, etching tus neeg sawv cev, siv los ua cov chaw tiv thaiv cov ntoo, thiab tseem siv tau rau kev tsim kho kho kom muaj xeb, kev lag luam hluav taws xob, raws li kev ntsuas hluav taws xob.

4. Siv los ua cov tshuaj tiv thaiv thiab cov kab mob uas tsis muaj cov kab mob.

5. Kev Ntsuam Xyuas reagent. Siv rau ceramic thiab iav saum npoo. Tshuaj tua kab mob. Kev npaj ntawm hydrogen fluoride hauv chav kuaj. plating.
