Chaw tsim tshuaj paus zoo nqi phosphority acid 85% CAS: 7664-38-2

Cov lus piav qhia luv luv:

Phosphorous acid tseem hu ua astophosphate (molecular qauv H3po4), cov tshuaj ntshiab rau cov kua ntshav khov ua kua lossis cov square crystal, tsw qab, tsw qab. 85% phosphorous acid yog ib qho tsis muaj xim, pob tshab lossis lub teeb me ntsis, kua tuab. Melting point 42.35℃, specific gravity 1.70, high boiling point acid, can be soluble with water at any ratio, boiling point 213℃ (losing 1/2 water), pyrophosphate will be generated. Thaum rhuab rau 300 ℃, nws tiav niam txiv metaphosphoric acid. Txheeb ze ceev faj 181.834. Soluble hauv dej, soluble hauv ethanol. Phosphorous acid yog ib qho unorganic acid nyob rau hauv cov tshuaj lom. Nws yog qhov nruab nrab thiab muaj zog acid. Nws cov acidity yog tsis muaj zog dua li cov sulfuric acid, thiab muaj zog dua li acetic acid, boric acid thiab carbonic acid. Thaum phosphorous acid reacts nrog sodium carbonate ntawm cov pH sib txawv, cov ntsev cov kua qaub sib txawv tuaj yeem tsim tau. Tuaj yeem txhawb cov tawv nqaij kom ua rau o, ua rau lub cev puas tsuaj. Lub ntsej muag zoo nkauj phosphorous acid erodes thaum rhuab hauv plooj (porcelain. Nws yog hygroscopic thiab ntim. Kev lag luam muaj cov kua hluav taws xob phosphorous acid yog hom tshuaj pleev tau muaj 482% h3po. Lub viscosity siab ntawm phosphorous acid tov yog vim muaj ntawm hydrogen bonds hauv kev daws.

Cov ntawv thov ntawm phosphorous acid

Daim ntawv thov cov phosphatates muaj raws li nram no: Hlau deg steel yeeb yaj kiab phosphorus kho mob, tsim cov roj electrolytic polishing; Polishing ntawm txhuas cov khoom; Kev tsim khoom ntau yam phosphate, pub -grade calcium phosphate, manganese phosphate, thiab potassium ntawm cov scorch phosphate; Kev lag luam kev lag luam; Kev lag luam kev lag luam; Nws yog siv los ua cov sodium glycerol phosphate thiab hlau ntsev phosphate, thiab tswj cov kua qaub thiab alkali thaum tsim penicillin; siv los ua zinc phosphate ua kev kho hniav; Yas rau catalyst rau phenolic Resin Shrinkage; Tshuaj lom neeg tshiab rau Dyes thiab nruab nrab ntau lawm; luam ntawv nws yog siv los npaj cov neeg sawv cev tu ntawm cov stains ntawm kev luam ntawv ntawm cov pos hniav luam ntawv. Qhov sib tw yog siv rau impregnating cov ntais ntawv, uas tuaj yeem ua rau cov kab mob hlawv tsis pom cov duab hluav taws xob, uas muaj kev nyab xeeb thaum siv; Lub Neej Rauv; Roj hmab rau qhov sib xyaw ntawm cov slurry thiab cov khoom siv raw ntawm cov khoom lag luam ntawm cov neeg sawv cev hauv Inorganic. Cov txheej txheem yog siv rau cov xim hlau tiv thaiv cov xim hlau; Kev lag luam khoom noj khoom haus yog siv raws li acidic seings.
1. Nws tsuas yog siv rau phosphate kev lag luam, electroplating kev lag luam, kev lag luam polishing, cov chiv kev lag luam, cov poov xab, thiab lwm yam hauv kev lag luam khoom noj khoom haus
2. Meej yog siv rau ethylene hydraulic ua haujlwm ntau lawm ntawm ethanol, muaj siab zoo ntsev, kev kho mob, tshuaj lom neeg.
3.
4. Feem ntau siv raws li analytical reagents
5. Rau qhov muaj peev xwm thiab kev tsom xam xim, thiab lwm yam.
6. Hauv kev tsim cov Silicon cov raj kav thiab cov yeeb yaj kiab ua ke, zaj duab xis txhuas feem ntau yog siv hluav taws xob cov hmoov txhuas. Aluminium zaj duab xis yuav tsum tau siv rau photoresses, thiab phosphate yog siv raws li acidic tu thiab corrosion tus neeg sawv cev. Tuaj yeem siv nrog acetic acid.
7. Nws tuaj yeem siv los ua tus neeg saib xyuas khoom noj ntawm cov kua qaub-los ntawm cov poov xab. Nws tuaj yeem siv rau cov neeg sawv cev rau cov seasing, cov kaus poom, thiab dej txias. Rau cov poov xab muaj txiaj ntsig rau brewing, tiv thaiv cov kab mob sib xyaw los ntawm kev yug menyuam.
8. Raws li tus neeg sawv cev noj zaub mov, chelating, antioxidant equiconed tus neeg sawv cev, thiab inrid acid-dog teb, uas tuaj yeem siv, cov dej qab zib, jelly thiab cola -type haus.
9. Ntuav dej yog siv los tsim ntau hom phosphate, sodium phosphate, sodium phosphate, sodium phosphate, thiab lwm yam. Refined phosphate yog siv rau calcium phosphate rau pub. Nws yog siv rau phosphorification ntawm cov hlau nto, sau cov qauv electrolytic polishing thiab tshuaj polishing kua rau polishing kua rau polishing ntawm cov khoom txhuas. Kev lag luam kws tshuaj siv tshuaj yog siv los tsim cov sodium glycerol phosphate, thiab lwm yam. Catalysts rau phenolic resaction, desiccants rau dyes thiab nruab nrab ntau lawm. Kev lag luam luam ntawv yog siv los npaj cov kev ntxuav tu ntawm cov stains ntawm kev luam ntawv version ntawm cov pos hniav luam ntawv. Nws tseem siv los npaj cov kua sib luag. Kev lag luam metallurgical yog siv los tsim cov av hluav taws hluav taws hluav taws thiab txhim kho lub neej ntawm steelmakaking cub hluav taws.
