Ceg, cov chelate tsim los ntawm chelating tus neeg sawv cev, los ntawm Greek lo lus chele, lub ntsiab lus roob hauv qab. Chelates zoo li crab claws tuav hlau ions, uas ruaj khov thiab yooj yim tshem tawm lossis siv cov hlau ions. Xyoo 1930, thawj chelate tau synthesized nyob rau hauv lub teb chaws Yelemees - Edta (Ethylened tus neeg mob, thiab tom qab ntawd lub xeem neeg ntxuav, kev lag luam txhua hnub, kev lag luam thiab lwm yam kev siv.
Tam sim no, cov tuam ntxhab tseem ceeb ntawm cov neeg sawv cev hauv lub ntiaj teb no suav nrog Basf, Dongxiao txheeb, Shijiazhuang Jack thiab lwm yam.
Thaj chaw Asia-Pacific yog qhov kev lag luam loj tshaj plaws rau cov neeg sawv cev chelating, nrog ntau tshaj 50% kev kho mob hauv kev ua lag luam, nrog kev saib xyuas dej, cov ntawv, khoom noj khoom haus thiab dej haus.
(Molecular qauv ntawm lub chelating tus neeg sawv cev edta)
Chelating cov neeg sawv cev tswj hwm hlau ions los ntawm chelating lawv cov ntau-ligands nrog cov hlau ion complexes los ua chelates.
Los ntawm cov tshuab no, nws tuaj yeem nkag siab tias ntau cov lwg me me nrog ntau cov nolecules muaj cov chelation xws li kev sib tw.
Ib qho ntawm feem ntau yog cov edta saum toj no, uas tuaj yeem muab 2 molechly attract fundsing nrog cov khoom siv calcium, thiab muaj peev xwm siv cov khoom siv tau ruaj khov nrog kev sib koom tes zoo heev. Lwm cov chelators feem ntau suav nrog sodium phytate xws li sodium gluconate tetcetate trisodium (mgda), thiab polyphosphates thiab polyamines.
Raws li peb txhua tus paub, txawm hais tias nyob rau hauv kais dej los yog hauv ntuj dej lub cev, muaj calcium, hlau, hlau, yuav coj cov hauv qab no los ntawm peb lub neej:
1. Cov ntaub npuag tsis huv, ua rau tso nyiaj yuam kev, cov tawv nqaij tawv thiab tsaus.
2. Tsis muaj kev ntxuav tu cov neeg saib xyuas kom haum rau ntawm cov khoom tawv, thiab ntsuas nyiaj tso nyiaj
3. Npleem tso nyob rau hauv tableware thiab khob iav
Dej hardness yog hais txog cov ntsiab lus ntawm calcium thiab magnesium hauv dej, thiab cov dej khov yuav txo cov kev ntxuav. Nyob rau hauv cov khoom noj tshuaj, tus neeg sawv cev chelating tuaj yeem cuam tshuam nrog calcium, frageries cov dej khov, yog li tsis muaj kev cuam tshuam nrog cov khoom ntxuav, yog li txhim kho cov txiaj ntsig ntawm cov khoom ntxhua khaub ncaws.
Tsis tas li ntawd, chelating tus neeg sawv cev kuj tseem tuaj yeem ua cov tshuaj sib xyaw ua ke ruaj khov thiab tsis tshua muaj kev cuam tshuam rau kev rhuav tshem thaum lub sijhawm ntev.
Qhov sib ntxiv ntawm tus neeg sawv cev rau cov tshuaj ntxuav ntxhua khaub ncaws tuaj yeem txhim kho cov dej huv, yog li cov khaub ncaws ntxhua khaub ncaws, yog li cov khaub ncaws ntxhua khaub ncaws, ua kom cov khaub ncaws zoo dua li ntawm cov khaub ncaws, txhim kho cov khaub ncaws siab, txhim kho cov kev ntxhua khaub ncaws, txhim kho cov kev ntxuav ua kom zoo ib yam. Txhim kho whiteness whiteness thiab softness, intuitive kev ua tau zoo tsis yog li grey thiab qhuav nyuaj.
Tsis tas li ntawd nyob rau hauv qhov nyuaj saum npoo tu thiab tabsware ntxuav, tus neeg sawv cev ntawm cov xab npum thiab cov nplai yuav tsis yooj yim dua, thiab cov nplai sib txawv yog qhov ntau pob tshab, thiab lub iav tsis dai dej zaj duab xis. Cov neeg sawv cev chelating kuj tseem tuaj yeem muab cov pa oxygen ua ke nrog cov huab cua kom tsim cov khoom ruaj khov uas inhibit cov oxidation ntawm cov hlau.
Tsis tas li ntawd, kev siv chelating ntawm chelating tus neeg sawv cev ntawm cov hlau ions kuj tseem siv hauv cov tshuaj yeeb nkab rau xeb tshem tawm.
