Ion yekutsinhana nzira ye silica sol precision casting.Iyo cation exchange resin inoshandisa yakasimba asidhi styrene cation exchange resin;iyo anion exchange tree inoreva isina simba basic styrene anion exchange resin.

Kutsinhana kweion ndiko kuita kwekuenzanisa.Maitiro ekuita ndeokuti kana silicic acid solution ine Na + ikapfuudzwa nemunwe wemuti wekuchinjana, Ma + inotsiva H + pane cation exchange resin.Naizvozvo, NAa + mugirazi remvura yakabviswa, uye H + cations, silicon ions uye SiO3 mu sodium silicate inoumba inoshanda dilute mhinduro ye silica sol uye inoyerera ichibuda.

Iko ion exchange quality ye silica sol ine hukama nezvinhu zvinotevera: dhigirii resin regeneration, kuenzanisa zvivakwa, kureba kweresin, kudzika kweiyoni, saizi yeion, etc. Iyo silica sol yakapfuura nepakati cation exchange column inonatswa uye yopfuura nepasina simba. basic anion resin exchange column kubvisa anion CL- mumvura kuti iwane imwe yakagadzikana.Iyo dilute silicon yakadzika chingamu inoyerera ichibuda mukoramu yekutsinhana ine yakanyanya kuderera uye inoda kuiswa.Kuti udzivise gelation panguva yekusungwa, stabilizer inofanira kuwedzerwa nokukurumidza musati waiswa.Iyo stabilizer inowanzova MOH (M is L, Na, K, Rb, Cs, NH4.NH2, nezvimwewo).Nhamba ye stabilizer inofanira kuva yakakodzera.Kana iri pasi pe1% yema moles eSiO2, zvakaoma kuita basa rekudzikamisa;kana ichipfuura 5% Ichaderedza kuchena kwechigadzirwa.Tora 5kg yepamusoro silica sol uye gadzirisa kukosha kwePH kusvika 78 ne10% NAOH mhinduro.Tora 900 g yegadziriso yemvura uye uzadze iyo mudhizaini yekudzikisira kuita iyo yekumisikidza pasi pekumanikidzwa kwakaderedzwa.Uye pamusimboti wekuchengeta mwero wemvura mumudziyo unogara uripo, zvishoma nezvishoma wedzera iyo yasara 4100g yekugadziridza mvura.Iyo tembiricha yekuisa yakachengetedzwa pa78 ° C, uye 900 g yesilica sol ine SiO220% uye Na200.33% PH ye9.6 yakagadzirwa, uye avhareji saizi yechikamu yaive ingangoita gumi nematanhatu mum.

Iyo ion yekutsinhana resin yakarasikirwa nekutsinhana kwayo mushure mekuchinjanisa ion.Inoda kugeza ne dilute hydrochloric acid uye kutsiva Na + pane resin neH9 + muHCL.Mapoka anoshanda eiyo ion exchange resin anoiswa oxidized kuti agadzirise resin uye adzorere huwandu hwekutsinhana.Mushure mekuzvarwa patsva, iyo ion yekutsinhana muti inoreva kuti inofanirwa kugezwa nemvura yakanyungudutswa kune yakatsanangurwa PH kukosha kwekushandisa kunotevera.

Kuitwa kwehunyanzvi hwesilica sol: SiO2 yemukati 20% 30% (H2SiO3 zvirimo> 26%) mwando 70% 80% chaiyo giravhiti 1.141.21 Na2O yemukati 0.4% 0.5% viscosity (coating 4) 10.9S inogona kuchengetwa kwegore rimwe
