Embodiment 1
[0035] The preparation method of the ceramic membrane filter element for printing and dyeing wastewater treatment of the present invention comprises the following steps:
[0036] (1) Preparation of support body:
[0037] ① Ingredients: Mix 300-mesh spherical bauxite aggregate, high-temperature binder, wood chips, phenolic vinyl ester resin T-158, and graphite evenly, of which spherical bauxite aggregate accounts for 95% of the total mass; the high-temperature binder accounts for 5% of the total mass of the spherical bauxite aggregate and the high-temperature binder; the porosity enhancer accounts for 8% of the total mass of the spherical bauxite aggregate and the high-temperature binder, and the resin accounts for 6% of the total mass of bauxite aggregate and high-temperature binder; the release agent accounts for 0.07% of the total mass of spherical bauxite aggregate and high-temperature binder;
[0038] ②Isostatic pressing: After the batching is completed, mix it evenly in ...
