Indlela yotshintshiselwano ye-Ion ye-silica sol echanekileyo yokuphosa.I-resin yokutshintshiselana nge-cation isebenzisa i-asidi eqinile ye-styrene cation exchange resin;Umthi wotshintshiselwano weanion ubhekisa kwintlaka ebuthathaka ye-styrene anion exchange resin.

Utshintshiselwano lwe-ion luyimpendulo elinganayo.Inkqubo yokusabela kukuba xa isisombululo se-asilicic acid esiqulethe i-Na + sidlula ngomnwe womthi wokutshintshiselana, i-Ma + ithatha indawo ye-H + kwi-resin ye-cation exchange.Ngoko ke, i-NAa + kwiglasi yamanzi isusiwe, kwaye i-H + cations, i-silicon ions kunye ne-SiO3 kwi-sodium silicate yenza isisombululo esisebenzayo se-silica sol kunye nokuphuma ngaphandle.

Umgangatho wotshintshiselwano we-ion we-silica sol unxulumene nezi zinto zilandelayo: iqondo lokuhlaziywa kwakhona kwe-resin, iimpawu zokulinganisa, ukuphakama kwe-resin, ubunzulu bokungena, ubungakanani be-ion, njl njl. Ikholamu yokutshintshiselana ye-anion esisiseko yokususa i-anion CL- kulwelo ukufezekisa imeko ezinzileyo.Itshungama ye-silicon edilulisiweyo ephuma kuluhlu lotshintshiselwano inoxinzelelo oluphantsi kakhulu kwaye kufuneka igxininiswe.Ukuze kuthintelwe i-gelation ngexesha lokugxininiswa, i-stabilizer kufuneka yongezwe ngokukhawuleza ngaphambi koxinzelelo.I-stabilizer ihlala i-MOH (M ngu-L, Na, K, Rb, Cs, NH4.NH2, njl.).Ubungakanani bokuzinzisa kufuneka bufaneleke.Ukuba ingaphantsi kwe-1% ye-moles ye-SiO2, kunzima ukudlala indima yokuzinzisa;ukuba idlula i-5% Iya kunciphisa ukucoceka kwemveliso.Thatha i-5kg ye-silica sol engentla kwaye ulungise ixabiso le-PH kwi-78 kunye ne-10% isisombululo se-NAOH.Thatha i-900 g yolwelo lohlengahlengiso kwaye uyigcwalise kwisinciphisi soxinzelelo ukuze uqhube uxinzelelo phantsi koxinzelelo oluncitshisiweyo.Kwaye ngokomgaqo wokugcina umgangatho wolwelo kwisikhongozeli ungaguquguquki, kancinane wongeza i-4100g eseleyo yolwelo olulungelelanisiweyo.Ukushisa okugxininiswayo kwagcinwa kwi-78 ° C, kunye ne-900 g ye-silica sol equkethe i-SiO220% kunye ne-Na200.33% PH ye-9.6 yalungiswa, kwaye ubungakanani be-particle ubukhulu bu malunga ne-16 mum.

I-resin yotshintshiselwano ye-ion ilahlekelwe amandla ayo otshintshiselwano emva kokutshintshiselana kwe-ion.Kufuneka uhlambe nge-dilute hydrochloric acid kwaye ubeke indawo ye-Na + kwi-resin nge-H9 + kwi-HCL.Amaqela asebenzayo e-ion exchange resin i-oxidized ukuvuselela i-resin kunye nokubuyisela amandla okutshintshana.Emva kokuhlaziywa, umthi wotshintshiselwano we-ion uthetha ukuba kufuneka uhlanjululwe ngamanzi adibeneyo kwixabiso elichaziweyo le-PH kusetyenziso olulandelayo.

Ukusebenza kobugcisa be-silica sol: Umxholo weSiO2 20% 30% (umxholo we-H2SiO3> 26%) ukufuma 70% 80% ubunzima obuthile 1.141.21 Isiqulatho seNa2O 0.4% 0.5% viscosity (i-coating 4) 10.9S ingagcinwa unyaka omnye
