Tuam Tshoj Tus Nqi Zoo Phosphorous Acid 85% CAS: 7664-38-2

piav qhia luv luv:

Phosphorous Acid tseem hu ua orthophosphate (cov qauv molecular H3PO4), cov khoom ntshiab rau cov xim tsis muaj pob tshab pob tshab kua lossis square crystal, tsis muaj ntxhiab, qaub saj.85% Phosphorous Acid yog cov xim tsis muaj xim, pob tshab lossis lub teeb me ntsis, cov kua tuab.Melting point 42.35 ℃, tshwj xeeb lub ntiajteb txawj nqus 1.70, siab boiling point acid, yuav soluble nrog dej nyob rau hauv ib tug ratio, boiling point 213 ℃ (poob 1/2 dej), pyrophosphate yuav generated.Thaum rhuab mus rau 300 ℃, nws ua metaphosphoric acid.kwv tij density 181.834.Soluble hauv dej, soluble hauv ethanol.Phosphorous Acid yog ib hom inorganic acid hauv Chemicalbook.Nws yog ib qho nruab nrab thiab muaj zog acid.Nws cov acidity tsis muaj zog dua li cov kua qaub uas muaj zog xws li sulfuric acid, hydrochloric acid thiab nitric acid, tab sis muaj zog dua li cov acids tsis muaj zog xws li acetic acid, boric acid thiab carbonic acid.Thaum Phosphorous Acid reacts nrog sodium carbonate ntawm pH sib txawv, cov kua qaub sib txawv tuaj yeem tsim.Muaj peev xwm ua kom cov tawv nqaij ua rau mob, ua rau lub cev puas tsuaj.Concentrated Phosphorous Acid erodes thaum rhuab hauv porcelain.Nws yog hygroscopic thiab kaw.Cov khoom lag luam muaj Phosphorous Acid yog cov kua nplaum uas muaj 482% H3PO.Qhov siab viscosity ntawm Phosphorous Acid tov yog vim muaj cov hydrogen bonds hauv cov tshuaj.

Kev siv ntawm phosphorous acid

Lub ntsiab daim ntawv thov ntawm phosphates yog raws li nram no: hlau nto steel yeeb nkab kho phosphorus, formulating electrolytic polishing kua thiab tshuaj polishing kua;polishing ntawm cov khoom siv aluminium;tsim ntau yam phosphate, pub-qib calcium phosphate, manganese phosphate, thiab poov tshuaj ntawm scorch phosphate;kev lag luam tshuaj;kev lag luam tshuaj;Nws yog siv los ua sodium glycerol phosphate thiab hlau phosphate, thiab tswj cov kua qaub thiab alkali thaum tsim penicillin;siv los ua zinc phosphate ua cov nplaum kho hniav;yas rau catalyst rau phenolic resin shrinkage;qhuav CHEMICALBOOK tus neeg sawv cev rau dyes thiab nruab nrab ntau lawm;luam ntawv Nws yog siv los npaj tus neeg saib xyuas ntawm cov stains ntawm cov ntawv luam tawm ntawm cov pos hniav.Lub match yog siv rau impregnating lub match stalk, uas yuav ua rau cov burned match stalks tsis greyed rau hauv charcoal zoo, uas yog kev ruaj ntseg thaum siv;Rauv lub neej;roj hmab rau coagulation ntawm slurry thiab raw khoom ntawm zus tau tej cov inorganic bonding agent;coatings yog siv rau hlau los tiv thaiv xeb xim;kev lag luam khoom noj khoom haus yog siv raws li acidic seasonings.
1. Nws yog tsuas yog siv rau kev lag luam phosphate, electroplating, polishing kev lag luam, qab zib -making kev lag luam, compound fertilizer, thiab lwm yam. Raws li ib tug pH, poov xab khoom noj khoom haus, thiab lwm yam.
2. Feem ntau yog siv rau ethylene hydraulic ntau lawm ntawm ethanol, siab-pure phosphate, kev kho mob manufacturing, tshuaj reagent.
3. Feem ntau yog siv los ua tshuaj chiv, tshuaj detergents, khoom noj khoom haus thiab pub additives, nplaim retardants thiab ntau yam phosphates.
4. Feem ntau yog siv los ua cov tshuaj analytical reagents
5. Rau kev muaj peev xwm thiab kev tshuaj ntsuam xim, thiab lwm yam.
6. Nyob rau hauv zus tau tej cov silicon dav hlau kav thiab integrated circuits, txhuas zaj duab xis yog feem ntau siv raws li electrode lead.Aluminium zaj duab xis yuav tsum tau siv rau photoresses, thiab phosphate yog siv los ua acidic tu thiab corrosion agent.Yuav siv tau nrog acetic acid.
7. Nws tuaj yeem siv los ua cov khoom noj khoom haus ntawm cov kua qaub-flavored thiab poov xab.Nws tuaj yeem siv rau cov kua qaub rau seasoning, cov kaus poom, thiab dej txias.Rau cov poov xab khoom noj khoom haus rau brewing, tiv thaiv cov kab mob sib xyaw los ntawm kev yug me nyuam.
8. Raws li tus neeg sawv cev ntawm cov poov xab, chelating agent, antioxidant efficiency agent, thiab inorganic acid -flavored agent, acid saj yog 2.3 mus rau 2.5, uas yuav siv tau rau composite seasoning, kaus poom, cheese, jelly thiab cola-hom dej qab zib.
9. Cov phosphate ntub dej feem ntau yog siv los tsim ntau hom phosphate, xws li ammonium phosphate, potassium dihydrogen phosphate, sodium phosphate, sodium phosphate, thiab lwm yam, thiab nyuaj phosphate.Refined phosphate yog siv rau calcium phosphate rau pub.Nws yog siv rau phosphorification ntawm hlau nto, formulating electrolytic polishing tov thiab tshuaj polishing kua rau polishing ntawm txhuas khoom.Kev lag luam kws tshuaj yog siv los tsim cov sodium glycerol phosphate, hlau phosphate, thiab lwm yam, thiab tseem siv los tsim zinc phosphate ua cov nplaum kho hniav ntawm lub tuam tsev kho hniav.Catalysts rau phenolic resin contraction, desiccants rau dyes thiab nruab nrab ntau lawm.Kev lag luam luam ntawv yog siv los npaj cov tshuaj ntxuav cov stains ntawm cov ntawv luam tawm ntawm cov pos hniav.Nws kuj yog siv los npaj kev sib tw ua kua dej.Kev lag luam metallurgical yog siv los tsim hluav taws kub phosphate hluav taws av nkos thiab txhim kho lub neej ntawm steelmaking furnaces.Nws yog coagulation ntawm roj hmab pulp thiab raw khoom rau zus tau tej cov inorganic nplaum.Kev lag luam txheej yog siv los ua hlau xeb xim.
10. Txiav txim siab chromium, npib tsib xee, kab civliv cov khoom xyaw, hlau xeb-pov thawj, roj hmab coagulants hauv steel, thiab txiav txim siab tsis-protein nitrogen, tag nrho cov compulinol, thiab tag nrho cov ntshav qabzib hauv cov ntshav.Crystal phosphate feem ntau yog siv rau kev tsim cov txheej txheem xws li microelectronics, high-zog roj teeb, laser iav thiab lwm yam txheej txheem tsim, thiab yog siv los ua high-purity catalysts thiab cov ntaub ntawv kho mob.
