Magnesium Sulphate Export Quality Standards for Global Buyers

Raws li cov khoom lag luam xa tawm nyob rau hauv lub ntiaj teb tshuaj ua lag luam, magnesium sulphate yog ua raws li cov qauv zoo los xyuas kom meej nws txoj kev nyab xeeb, ua tau zoo, thiab ua raws li cov kev cai thoob ntiaj teb. Rau cov neeg yuav khoom thoob ntiaj teb thiab cov neeg xa khoom, kev nkag siab txog cov qauv zoo no yog qhov tseem ceeb rau kev nrhiav cov khoom siv siab -cov khoom zoo, zam kev ua yuam kev kim, thiab xyuas kom meej tias magnesium sulphate ua tau raws li qhov xav tau ntawm lawv daim ntawv thov tshwj xeeb.

 

Tus qauv zoo tshaj plaws rau magnesium sulphate yog nws qib purity. Nyob ntawm daim ntawv (anhydrous lossis heptahydrate), qhov tsawg kawg nkaus purity yuav tsum sib txawv. Rau anhydrous magnesium sulphate, qhov tsawg kawg nkaus purity feem ntau yog 98% lossis siab dua, thaum heptahydrate magnesium sulphate yuav tsum muaj qhov purity tsawg kawg yog 99% lossis siab dua. Cov qib purity yog ntsuas los ntawm feem pua ​​​​ntawm magnesium sulphate nyob rau hauv cov khoom, nrog impurities xws li hnyav hlau, chloride, thiab ya raws nruj me ntsis txwv.

 

Cov kab mob hlau hnyav yog qhov kev txhawj xeeb tseem ceeb hauv cov qauv zoo ntawm magnesium sulphate. Cov kev cai thoob ntiaj teb, xws li cov teeb tsa los ntawm European Union (EU), Tebchaws Asmeskas Cov Khoom Noj thiab Tshuaj Tshuaj (FDA), thiab Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv (WHO), txwv cov qib ntawm cov hlau hnyav xws li txhuas, arsenic, cadmium, thiab mercury. Piv txwv li, EU txwv cov ntsiab lus ua rau tsawg dua 10 ppm (ib feem ntawm ib lab) hauv cov zaub mov- qib thiab kev ua liaj ua teb- qib magnesium sulphate.

 

Cov ntsiab lus noo noo yog lwm qhov tseem ceeb rau magnesium sulphate. Anhydrous magnesium sulphate yuav tsum muaj cov dej noo siab tshaj plaws ntawm 1% lossis tsawg dua, vim tias cov dej noo ntau dhau tuaj yeem ua rau clumping thiab txo cov khoom ruaj khov. Heptahydrate magnesium sulphate, thaum ib txwm muaj dej, yuav tsum muaj cov dej noo nyob hauv thaj tsam ntawm 45-55% kom ntseeg tau tias nws cov qauv siv lead ua thiab solubility.

 

Ntxiv nrog rau purity thiab noo noo cov ntsiab lus,magnesium sulfateexport cov qauv zoo kuj muaj xws li particle loj, solubility, thiab pH qib. Particle loj cuam tshuam rau cov khoom tuav thiab daim ntawv thov, nrog rau kev lag luam sib txawv uas yuav tsum tau muaj qhov loj me me (piv txwv li, hmoov zoo rau cov tshuaj pleev ib ce, cov muaju loj rau kev ua liaj ua teb). Solubility yog ib qho tseem ceeb rau kev siv xws li kev kho dej thiab kev ua liaj ua teb tshuaj tsuag, vim tsis zoo soluble magnesium sulphate yuav tsis xa cov txiaj ntsig xav tau. pH qib kuj tseem ceeb, vim tias lawv tuaj yeem cuam tshuam cov khoom sib raug zoo nrog lwm cov tshuaj thiab nws cov kev ua tau zoo hauv cov ntawv thov tshwj xeeb.

 

Cov neeg yuav khoom thoob ntiaj teb yuav tsum tau thov Daim Ntawv Pov Thawj Kev Ntsuam Xyuas (CoA) los ntawm cov neeg muag khoom los xyuas kom meej tias magnesium sulphate ua tau raws li cov qauv zoo thoob ntiaj teb. Lub CoA yuav tsum muaj cov ncauj lus kom ntxaws txog purity, noo noo, qib hlau hnyav, particle loj, thiab lwm yam zoo. Tsis tas li ntawd, cov neeg yuav khoom yuav tsum xyuas kom meej tias cov khoom ntim tau ua raws li cov kev cai thauj khoom thoob ntiaj teb, siv cov khoom ntub dej -cov ntaub ntawv pov thawj los tiv thaiv clumping thiab paug thaum thauj. Los ntawm kev ua raws li cov qauv zoo no, cov neeg yuav khoom thoob ntiaj teb tuaj yeem ua kom ntseeg tau tias lawv tau txais txiaj ntsig zoo - magnesium sulphate uas ua tau raws li lawv cov kev xav tau tshwj xeeb thiab ua raws li cov cai hauv zos.
