Indlela yokushintshanisa i-ion yokusakaza okunembayo kwe-silica sol.I-cation exchange resin isebenzisa i-acid eqinile ye-styrene cation exchange resin;isihlahla se-anion exchange sibhekisela ku-resin eyisisekelo ye-styrene anion exchange resin.

Ukushintshaniswa kwe-ion kuwukusabela kokulingana.Inqubo yokusabela iwukuthi lapho isisombululo se-asilicic acid esiqukethe i-Na + sidlula ngomunwe wesihlahla sokushintshisana, i-Ma + ithatha indawo ka-H + ku-resin yokushintshanisa i-cation.Ngakho-ke, i-NAa + engilazini yamanzi isusiwe, futhi i-H + cations, i-silicon ions kanye ne-SiO3 ku-sodium silicate yakha isisombululo esisebenzayo se-silica sol bese siphuma.

Ikhwalithi yokushintshisana kwe-ion ye-silica sol ihlobene nezici ezilandelayo: izinga lokwenziwa kabusha kwe-resin, izakhiwo zebhalansi, ukuphakama kwe-resin, ukujula kokugeleza, usayizi we-ion, njll. I-silica sol edlula kukholamu yokushintshisana ye-cation iyahlanjululwa bese idlula ebuthaka. ikholomu yokushintshanisa i-anion resin eyisisekelo ukuze kukhishwe i-anion CL- oketshezini ukuze kuzuzwe isimo esizinze kakhudlwana.I-silicon dilute deep gum egeleza iphuma kukholomu yokushintshisana inokugxila okuphansi kakhulu futhi idinga ukugxiliswa.Ukuze uvimbele i-gelation ngesikhathi sokuhlushwa, i-stabilizer kufanele ifakwe ngokushesha ngaphambi kokugxila.I-stabilizer ivame ukuba yi-MOH (M is L, Na, K, Rb, Cs, NH4.NH2, njll.).Inani le-stabilizer kufanele lifanele.Uma ingaphansi kwe-1% yama-moles we-SiO2, kunzima ukudlala indima yokuzinza;uma idlula i-5% Izonciphisa ukuhlanzeka komkhiqizo.Thatha u-5kg we-silica sol engenhla bese ulungisa inani le-PH libe ngu-78 ngesisombululo se-NAOH esingu-10%.Thatha u-900 g woketshezi olulungisiwe bese ulugcwalisa kusinciphisi sokucindezela ukuze wenze ukugxila ngaphansi kwengcindezi encishisiwe.Futhi ngomgomo wokugcina izinga le-liquid esitsheni lingashintshi, kancane kancane wengeze u-4100g osele wokulungisa uketshezi.Izinga lokushisa lokuhlushwa laligcinwe ku-78 ° C, kanye no-900 g we-silica sol equkethe i-SiO220% ne-Na200.33% PH ye-9.6 yalungiswa, futhi usayizi wezinhlayiyana ojwayelekile wawungaba ngu-16 mum.

I-resin yokushintshanisa i-ion ilahlekelwe amandla ayo okushintshana ngemva kokushintshaniswa kwe-ion.Udinga ukugeza nge-dilute hydrochloric acid bese ufaka esikhundleni se-Na + ku-resin nge-H9 + ku-HCL.Amaqembu asebenzayo we-ion exchange resin afakwe i-oxidized ukuze akhiqize kabusha inhlaka futhi abuyisele amandla okushintshanisa.Ngemva kokukhiqizwa kabusha, isihlahla sokushintsha i-ion sisho ukuthi kufanele sigezwe ngamanzi acwebile sibe senani elingu-PH elishiwo ukuze sisetshenziswe ngokulandelayo.

Ukusebenza kwezobuchwepheshe kwe-silica sol: Okuqukethwe kwe-SiO2 20% 30% (okuqukethwe kwe-H2SiO3> 26%) umswakama 70% 80% amandla adonsela phansi athize 1.141.21 Okuqukethwe kwe-Na2O 0.4% 0.5% viscosity (coating 4) 10.9S ingagcinwa unyaka owodwa
