Poov tshuaj ntsev

Phosphates hu ua tshuaj tsevneeg ntawm txawv co nrog phosphoric acid. Tam sim no, muaj ntau ntau ntau ntau yam ntawm phosphates, uas yog siv nyob rau hauv ntau yam teb ntawm kev ua si. Tsis kos thiab poov tshuaj ntsev, uas yog feem ntau siv raws li ib tug antioxidant thiab bactericidal tshuaj nyob rau hauv lub lag luam ua noj. Nws yuav tsum tau muab sau tseg tias antioxidants yog cov tshuaj uas inhibit oxidation lwm yam. Piv txwv li, xav txog lub tom Kua, uas yog nyob rau hauv cov huab cua darkens. Qhov no tshwm sim vim hais tias cov pa nyob rau hauv cov huab cua oxidizes hlau muaj nyob rau hauv lub txiv hmab txiv ntoo. Yog hais tias poov tshuaj ntsev ncuav nyob rau hauv qhov chaw coj ib tug tom, tus oxidation txheej txheem yuav qeeb ntau lub sij hawm. Yog li, cov metabolism hauv yog suppressed nyob rau hauv lub cev ntawm cov kab mob. Uas yog vim li cas nws yog siv raws li ib tug preservative.

Nws yuav tsum tau muab sau tseg tias tag nrho cov tebchaw ntawm phosphate, uas tshwm sim nyob rau hauv cov xwm, yog orthophosphates. Nyob rau hauv feem ntau tus neeg mob, poov tshuaj orthophosphates siv nyob rau hauv cov zaub mov kev lag luam (phosphoric acid ntsev), yog ib tus uas yog E340. Nyob rau hauv kev lag luam, poov tshuaj orthophosphate E340 hu ua monophosphate, nws yog ib tug khoom noj khoom haus additive siv raws li ib tug acidity regulator, ib ya ceev neeg saib xyuas thiab stabilizer, coloring retainer amplifier antioxidant kev txiav txim. Qhov no additive muaj cov nram qab tshuaj mis: KH2PO4, nws yog ib co soluble nyob rau hauv dej thiab muaj hauv daim ntawv ntawm ib tug granular dawb hmoov.

Phosphoric acid, interacting nrog poov tshuaj carbonate, txoj kev poov tshuaj ntsev uas nws mis yog K3PO4. Nws yog siv raws li ib feem ntawm xab npum additives nyob rau hauv bakery thiab confectionery khoom, dej qab zib thiab khoom noj siv mis, raws li zoo raws li kua zaub, pastas thiab cov kua ntsw, teas, cheese, cov nqaij thiab cov ntses khoom, vas nthiv zaub mov. Nyob rau hauv tas li ntawd, nws yog siv raws li ib tug stabilizer ntawm ntsuab zaub, vim hais tias nws txhawb nqa lub acidity ntawm ib tug nruab nrab ib puag ncig. Nyob rau hauv K3PO4 tshuaj no yog siv rau kev tiv thaiv thiab kev kho mob ntawm cov kab mob xws li hypophosphatemia, thiab nyob rau hauv industrial qhuav - raws li additives rau cov xim tsev, xeb inhibitors thiab ntau yam haus dej kom ntau rau drilling.

Nws yuav tsum tau muab sau tseg tias poov tshuaj ntsev, ib feem ntawm cov hmoov ua rau yus muaj zog tshuaj lom zog surfactants. Lawv pib sib txeem mus rau hauv tib neeg lub cev los ntawm daim tawv nqaij, ua rau kom nws cov degreasing, ua kom puas cell week, li no kom txhob muaj tus tiv thaiv muaj nuj nqi ntawm daim tawv nqaij. Surfactants, tob tob mus rau hauv cov hlab ntsha nyob rau hauv daim tawv nqaij, nkag mus rau hauv cov hlab ntsha thiab kis thoob plaws hauv lub cev, uas muaj txhawb mus rau ib tug ua txhaum cai ntawm thaj chaw ntawm cov ntshav thiab cov tsis muaj zog.

Yog li, rau hnub tim, poov tshuaj ntsev twb siv raws li ib tug P chiv, raws li ib feem ntawm cov kua thiab hmoov detergents thaum lub sij hawm drilling ua hauj lwm. Tsis tas li ntawd nws yog siv nyob rau hauv lub cement thiab textile industries, qhov tseeb thaum lub xov npaj rau coloring los yog tshuaj dawb tso, nyob rau hauv cov zaub mov kev lag luam rau loosening lub khob noom cookie, nyob rau hauv cov tshuaj rau qhov kev npaj ntawm cov tshuaj, hniav pastes los yog hmoov. Muaju ntawm poov tshuaj ntsev yog siv raws li ferroelectric los yog piezoelectric khoom, cov tshuaj tua kab, additives rau roj thiab lwm yam.

Txawm li cas los, nws yog ib nqi nco ntsoov hais tias tus phosphates adversely cuam tshuam tib neeg lub cev, yuav ua tau rau malfunctions nyob rau hauv cov ntaub ntawv yog tias ib tug neeg yog raug rau lawv rau ib ntev lub sij hawm nyhuv. Uas yog vim li cas ntau lub teb chaws tau tso tseg kev siv ntawm phosphates nyob rau hauv cov zaub mov thiab cov neeg siv industries. Nyob rau hauv peb lub teb chaws, lawv siv yog tso cai, ces nws yog feem ntau nyob rau hauv cov ntawv uas muaj ntau yam khoom los yog tsev neeg cov cuab yeej ua tau raws li cov los E340, piv txwv li poov tshuaj ntsev.
