Sodium Tripolyphosphate (STPP) yog ib yam khoom siv tshuaj inorganic tseem ceeb uas siv dav hauv kev lag luam hauv tsev neeg thiab tshuaj ntxuav khaub ncaws vim nws cov khoom zoo heev chelating, dispersing, emulsifying, thiab pH-buffering. Hauv qab no yog nws cov ntawv thov tshwj xeeb thiab cov txheej txheem ua haujlwm:
1. Ua ib yam tshuaj ntxuav tsev (Thawj daim ntawv thov)
Kev Ua Kom Dej Mos:
STPP ua tau zoo chelates calcium (Ca²⁺) thiab magnesium (Mg²⁺) ions hauv dej, tiv thaiv lawv los ntawm kev tsim cov xab npum uas tsis yaj nrog surfactants, yog li txhim kho kev ntxuav kom zoo (tshwj xeeb tshaj yog nyob rau hauv cov chaw dej tawv).
Kev tawg ntawm av:
Los ntawm kev nqus cov av qeeg, STPP muab hluav taws xob, faib lawv rau hauv dej thiab tiv thaiv kev rov ua dua rau ntawm cov ntaub, tswj cov ntaub dawb.
Kev ntsuas pH:
Tswj tau qhov chaw ntxuav alkaline (pH 9–10), ua kom lub zog ntxuav ntawm cov surfactants zoo dua, tshwj xeeb tshaj yog tawm tsam cov roj av.
Kev Ntxuav Ua Ke:
Ua haujlwm sib koom tes nrog anionic surfactants (piv txwv li, LAS), txo cov tshuaj surfactant thaum txhim kho kev ua haujlwm ntxuav.
2. Daim Ntawv Thov Hauv Cov Tshuaj Ntxuav Tshuab Ntxuav Phaj Tsis Siv Neeg
Tus Neeg Sawv Cev Tiv Thaiv Kev Sib Nraus:
Tiv thaiv kom cov tshuaj ntxuav tais diav tsis txhob lo rau hauv cov huab cua noo, ua kom cov hmoov ntws tau yooj yim.
Kev Tshem Tawm Cov Khoom Noj Khoom Haus:
Rhuav cov organic stains xws li cov protein thiab cov hmoov txhuv nplej siab, txo cov khoom seem ntawm cov tais diav.
3. Lwm Cov Tshuaj Siv Hauv Tsev Neeg
Cov Khoom Siv Saib Xyuas Tus Kheej:
Siv me me hauv cov tshuaj txhuam hniav thiab tshuaj zawv plaub hau ua cov dej mos lossis cov khoom ruaj khov.
Cov Neeg Ua Haujlwm Ntxuav Kev Lag Luam:
Siv rau hauv kev kho qhov chaw hlau thiab kev ntxuav khoom siv rau nws cov teebmeem chelating thiab dispersing.
4. Kev Txhawj Xeeb Txog Ib Puag Ncig Thiab Lwm Txoj Kev Xaiv
Tej Teeb Meem Ib puag ncig:
Kev tso tawm ntawm STPP tuaj yeem ua rau eutrophication (algae blooms) hauv cov dej, ua rau muaj kev txwv lossis txwv tsis pub ua hauv qee thaj chaw (piv txwv li, EU, Nyiv).
Lwm txoj hauv kev:
Cov tshuaj ntxuav uas tsis muaj phosphate feem ntau siv cov zeolites (4A zeolite), polycarboxylates (PAA), lossis sodium citrate ua cov khoom hloov pauv, txawm hais tias lawv qhov kev ua tau zoo tag nrho (piv txwv li, kev ua haujlwm chelation, tus nqi) tseem tsis tau zoo li STPP.
5. Xwm txheej ntawm kev ua lag luam
Siv Txuas Ntxiv Hauv Cov Tebchaws Uas Tseem Tab Tom Tsim Kho:
Hauv cov cheeb tsam xws li Tuam Tshoj thiab Is Nrias teb, STPP tseem yog ib qho tseem ceeb uas tsim cov tshuaj ntxuav (uas suav txog 20% -30% ntawm cov tshuaj) vim nws tus nqi qis thiab ua haujlwm tau zoo.
Khaws cia rau hauv Kev Ntxuav Hauv Chaw Lag Luam:
Qee cov tshuaj ntxuav hauv kev lag luam uas muaj zog heev tseem siv STPP raws li txoj cai thaum qhov kev xav tau ntxuav nruj heev.
Xaus lus
Qhov tseem ceeb ntawm STPP hauv kev lag luam hauv tsev thiab tshuaj ntxuav tes yog nws cov khoom siv ua vaj tse ntau yam. Txawm hais tias muaj kev txhawj xeeb txog ib puag ncig, nws tseem tsis tuaj yeem hloov pauv tau hauv qee qhov kev siv uas lwm txoj hauv kev siv tshuab lossis kev lag luam tsis ua haujlwm. Cov qauv yav tom ntej yuav tsom mus rau kev tsim cov tsev ua vaj tse uas zoo rau ib puag ncig thiab txhim kho cov thev naus laus zis rov ua dua tshiab ntawm STPP.
