Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with embodiment:
[0032] Ti 4 o 7 The preparation method of the ceramic microfiltration membrane electrode of coating, comprises the following steps:
[0033] (1) Ti 4 o 7 Preparation of precursor sol:
[0034] Put 10g of PVA in a beaker, pour deionized water to 100ml, and then place the beaker on a heating plate (IKA, RT-10) at 105°C to dissolve the PVA. During the dissolution process, add an appropriate amount of deionized water to supplement deionization Evaporation loss of water; add 20g TiO accordingly after cooling 2 , 2gPAA, 1.5g glycerol and 1.2gPVP and stirred, finally dilute to 100ml with deionized water; mechanically stir the sol with a stirrer (IKA, RW-20) at 900rpm to enhance TiO 2 Dispersibility in the sol, Ti can be obtained after stirring 4 o 7 Precursor sol;
[0035] (2) Ti 4 o 7 Preparation of precursor gel-coated ceramic microfiltration membranes:
[0036] Ti ...
