Microfiltration ceramic coating liquid, quartz microfiltration ceramic membrane and preparation method and application of quartz microfiltration ceramic membrane
The invention provides a microfiltration ceramic coating liquid, a quartz microfiltration ceramic membrane and a preparation method and application thereof, and relates to the technical field of inorganic ceramic membranes. The invention provides a microfiltration ceramic coating liquid. The microfiltration ceramic coating liquid comprises a component A and a dispersing agent, the component A comprises the following components in parts by mass: 14-22 parts of SiO2, 49-55 parts of a binder and 28-31 parts of water; the mass ratio of the component A to the dispersing agent is 1: (0.013-0.026). According to the microfiltration ceramic coating liquid, SiO2 serves as a coating liquid solid phase and has the advantages of being good in selectivity and controllable in membrane pore diameter in a large range, the microfiltration ceramic coating liquid adopts the binder and the dispersing agent in a certain proportion, when the microfiltration ceramic coating liquid is applied to preparation of a ceramic membrane, the pore diameter of an obtained membrane layer is uniform, and the pure water flux of the ceramic membrane can be correspondingly improved.
本发明提供了一种微滤陶瓷涂膜液、石英微滤陶瓷膜及其制备方法和应用，涉及无机陶瓷膜技术领域。本发明提供了一种微滤陶瓷涂膜液，包括组分A和分散剂；所述组分A包括以下质量份数的组分：SiO214～22份、粘结剂49～55份和水28～31份；所述组分A和分散剂的质量比为1：(0.013～0.026)。在本发明中，SiO2作为涂膜液固相，具有选择性好、膜孔径在大范围内可控的优点，本发明所述微滤陶瓷涂膜液采用一定比例的粘结剂和分散剂，使得该微滤陶瓷涂膜液应用于制备陶瓷膜时，所得膜层孔径均一，相应地能够提升陶瓷膜的纯水通量。
