Nrog ntau cov kua qaub, orthophosphoric acid siv nws qhov chaw hwm. Nws siv nyob rau qee qhov chaw ntawm kev lag luam tau ntev ntev nws tus kheej.
Meet phosphoric acid
Cov tshuaj no zoo li cas? Nws yog cov kua uas yuav luag tsis muaj xim lossis nrog cov xim daj. Nyob rau hauv chav tsev kub, nws tshwm sim raws li cov pob zeb diamond-puab crystals. Feem ntau xws li cov kua qaub yog hu ua kev daws ntawm 85% concentration, uas yog cov kua zoo li syrup nrog tag nrho tsis hnov tsw. Orthophosphoric acid yog soluble hauv dej thiab ntau cov kuab tshuaj. Piv txwv li, hauv ethanol. Yog tias, thaum cua sov, qhov kub siab tshaj 213 degrees, cov tshuaj no hloov mus ua pyrophosphoric acid.
Muaj 2 ntau yam ntawm cov khoom no:
- food acid;
- kev lag luam.
Orthophosphoric acid: daim ntawv thov
Txog hnub no, cov tshuaj nonyob rau hauv kev thov nyob rau hauv ntau industries. Qhov twg tsuas yog phosphoric acid tsis pom. Nws daim ntawv thov tuaj yeem muab faib ua 2 hom: hauv kev lag luam zaub mov thiab tsis yog khoom noj.
Food Phosphoric Acid
Hom no yog siv rau kev tsim khoom ntawm qee yam khoom. Piv txwv li:
- Raws li tus neeg tswj xyuas acidity hauv cov dej haus ntau lawm.
- Raws li acidifier hauv cheeses thiab ua tiav cheeses.
- Nyob rau hauv kev tsim ntawm qee hom hnyuv ntxwm.
- Nyob rau hauv bakery ua ib feem ntawm ci hmoov.
- Thaum ua qab zib.
Cov tshuaj no hauv kev tsim khoom muaj nws tus kheej tsim - antioxidant E338.
Tsis yog zaub mov phosphoric acid
Nyob hauv ntau qhov chaw ntawm kev tsim khoom, nws tsis tuaj yeem ua yam tsis muaj cov tshuaj hu ua phosphoric acid. Nws daim ntawv thov yog tsim nyog:
- Kev ua liaj ua teb. Tshwj xeeb tshaj yog nyob rau hauv ib qho kev lag luam xws li tsiaj txhu. Kev daws ntawm cov kua qaub no suav nrog hauv mink zaub mov rau kev tiv thaiv urolithiasis hauv cov tsiaj.
- Hauv kev tshawb fawb, nws yog siv rau kev tshawb fawb uas tau ua hauv molecular biology.
- Nyob hauv kev tsim khoom, nws yog siv los ua flux thaum soldering ntawm stainless hlau, ntawm tooj liab.
Yuav ua li cas nrog xeb?
Cov lus teb yog yooj yim: orthophosphoric acid yuav pab tau koj. Kev siv cov tshuaj tiv thaiv no tiv thaiv corrosion. Qhov tseeb yog tias nws, tsis zoo li ntau lwm tus, muaj kev nyab xeeb rau cov hlau. Kev kho phosphoric acidQhov saum npoo tsim ib zaj duab xis tiv thaiv uas tiv thaiv kev puas tsuaj ntxiv. Feem ntau nws tuaj yeem pom hauv cov khoom uas tsim los tiv thaiv xeb. Yog li ntawd, nws yog siv rau hauv tsev so thiab tsev noj mov ua lag luam.
Qhov mob ntawm phosphoric acid
Txawm li cas los xij (nrog rau cov txiaj ntsig) kuj muaj qhov tsis zoo ntawm kev siv phosphoric acid.
- Nws tuaj yeem ua rau acidity ntawm lub cev thiab ua rau chim siab.
- Nws cuam tshuam rau calcium. Displaces nws los ntawm cov hniav thiab pob txha. Yav dhau los, phosphoric acid feem ntau tau siv hauv kev kho hniav kom tshem tawm cov enamel. Kev siv nws tau txwv tsis ntev los no vim qhov tseeb.
- Kev siv cov khoom no txhua hnub hauv cov zaub mov yuav ua rau ntuav, xeev siab, tsis qab los.
- Phosphoric acid ua rau mob hnyav rau ntawm daim tawv nqaij.
Ua li ntawd, kev siv cov tshuaj no tau tso cai hauv cov tebchaws Russia, EU thiab yav dhau los CIS. Thaum siv rationally thiab txawj ntse, phosphoric acid yog cov txiaj ntsig zoo.

Kev kho cua txias: xaiv lub tuam txhab, xaus daim ntawv cog lus, cov cai rau kev sau npe, kev ua haujlwm ua tiav, cov lus qhia tu, cov cai thiab kev ua haujlwm nyab xeeb
Lub luag haujlwm tseem ceeb ntawm lub tshuab ua pa yog muab kev nkag mus thiab tso pa tawm, nrog rau nws qhov pom thiab tswj qhov kub thiab txias. Txhawm rau kom cov haujlwm no ua tiav tag nrho, nws yog ib qho tsim nyog yuav tsum tau nruab cov cuab yeej tshwj xeeb, nrog rau kev teeb tsa lub tshuab blower. Kev tu lub tshuab cua txias thiab qhov cua tshuab yog qhov yuav tsum tau ua rau ob qho tib si pej xeem thiab kev lag luam
Kuv yuav tsum thov rau Kws Qhia Ntawv ntawm Kev Nyab Xeeb Kev Nyab Xeeb?
Cov kws tshaj lij hauv kev ruaj ntseg nyiaj txiag yog qhov xav tau zoo hauv cov koom haum pej xeem thiab kev lag luam ntawm ntau yam. Nws puas tsim nyog nkag mus rau hauv lub tsev kawm ntawv no? Puas nyuaj kawm nyob ntawd? Nov yog qhov peb tsab xov xwm hais txog
Tus kws tshaj lij kev nyab xeeb ua haujlwm: piav qhia txoj haujlwm. Tus Kws Paub Txog Kev Nyab Xeeb Kev Ua Haujlwm: Lub luag haujlwm tseem ceeb
Raws li koj paub, txhua tus neeg ua haujlwm hauv ib lub lag luam yuav tsum muaj lawv tus kheej cov lus piav qhia. Tus kws tshaj lij tiv thaiv kev ua haujlwm tsis muaj kev zam rau txoj cai no. Nws, zoo li lwm tus neeg ua haujlwm, muaj ntau lub luag haujlwm thiab kev ua haujlwm uas yuav tsum muaj kev nthuav qhia ntxaws ntawm daim ntawv
Kev nyab xeeb thiab poob ntawm tus nqi ntawm kev nyab xeeb
Muaj hom kev nyab xeeb. Ua haujlwm nrog kev nyab xeeb, kev tswj hwm kev sib raug zoo hauv hom haujlwm no. Dab tsi txiav txim siab qhov poob ntawm tus nqi ntawm kev nyab xeeb
Kev nqis peev zoo ntawm kev nyab xeeb. Lub tswv yim ntawm kev lag luam kev nyab xeeb. Hom kev ruaj ntseg tseem ceeb
Tsis ntev los no, ntau thiab ntau tus neeg xaiv los nqis peev hauv kev nyab xeeb raws li txoj hauv kev los nqis peev. Qhov no ua rau kev txhim kho ntawm kev lag luam kev nyab xeeb. Kev xaiv muaj peev xwm ntawm cov cuab yeej peev yog ua tau tsuas yog tom qab kev ntsuam xyuas zoo ntawm cov peev txheej ntawm kev nyab xeeb
