Ion txauv resins tuaj yeem ua cov hmoov, tsis tu ncua granules, lossis cov duab kheej kheej raws li xav tau. Cov ion txauv resins siv nyob rau hauv cov tshuaj dej kho yog kheej kheej, ib qho kev xaiv zoo raws li cov ntsiab lus ntawm cov tshuaj lom neeg engineering thiab cov kev xav tau ntawm kev siv.
1. Dej Dynamics Zoo
Ped Porosity: Spherical resins, thaum random packed, tuaj yeem tsim ib lub txaj nrog cov porosity zoo heev, feem ntau ntawm 0.36 thiab 0.43 (txhais tau tias kwv yees li 36% -43% ntawm lub txaj txaj ntim yog qhov chaw muaj dej ntws). Tus nqi ruaj khov no tso cai rau kev suav cov dej dynamics thiab cov qauv tsim.
Kev sib piv siab poob: Ntawm qhov sib npaug ntawm qhov ntws thiab lub txaj siab, qhov system siab poob uas tsim los ntawm cov khoom siv tsis tu ncua tuaj yeem ua tau 30% mus rau 50% lossis ntau dua li cov khoom siv kheej kheej.
Tshem tawm cov channeling: Ib qho dej zoo-tsim lub txaj spherical resin txaj tuaj yeem tswj tau qhov channeling kom tsawg dua 1% ntawm lub txaj ntim, thaum channeling hauv cov txaj tsis tu ncua tuaj yeem ncav cuag 10% -15%, ua rau muaj ntau cov resin "tsis ua haujlwm" thiab kev siv qis heev.

2. Mechanical Strength
Lub zog ntawm resin feem ntau ntsuas los ntawm "sphericity" thiab "nrhiav tus nqi".
Sphericity: Siab -kev lag luam zoo ion txauv resins feem ntau xav tau ib qho sphericity (feem pua ntawm cov khoom kheej kheej tiag tiag) ntawm ntau dua 95%. Lub siab sphericity yog qhov yuav tsum tau ua ua ntej kom ntseeg tau cov lus hais saum toj no hydrodynamic zoo thiab lub zog.
Hnav Rate: Hauv cov qauv kuaj kuaj (xws li ntsuas qhov nyiaj ntawm cov khib nyiab zoo tsim tom qab muaj kev ntxhov siab thiab hnav), tus nqi txhua xyoo ntawm cov khoom siv kheej kheej tuaj yeem qis li 0.5% -3%. Cov khoom siv tsis tu ncua lossis cov khib nyiab uas tsim los ntawm kev hnav tuaj yeem txhaws cov dej ntws sab saud, ua rau muaj kev nce siab hauv qhov sib txawv thiab muaj peev xwm ua kom lub voj voog ua haujlwm luv dua li 20%.
3. Volumetric Exchange Peev xwm
Kev sib pauv muaj peev xwm yog qhov qhia txog kev ua haujlwm tseem ceeb ntawm cov cob, feem ntau qhia hauv mol / L lossis g / L.
Because spherical resin has the smallest specific surface area (surface area per unit volume), it can achieve the densest packing in a fixed-volume exchange column. Qhov no txhais tau hais tias nyob rau hauv 1 cubic meter pauv tank, qhov tseeb resin ntim ntim nrog spherical cob yuav ncav cuag ~ 0.65 m³, thaum irregularly zoo li resin tsuas yog ~ 0.58 m³.
Qhov txiaj ntsig ncaj qha yog tias tag nrho cov peev txheej pauv pauv ntawm cov kheej kheej yog feem ntau 5% -15% siab dua li cov khoom zoo sib xws nrog cov duab tsis zoo. Qhov no ncaj qha txuas rau lub voj voog dej ntau lawm, txo cov kev tsim dua tshiab, thiab txhim kho kev lag luam.
