End-capping method of tubular ceramic membrane
The invention relates to the technical field of membrane separation, and particularly discloses an end-capping method of a tubular ceramic membrane, which comprises the following steps of preparation of end-capping slurry: mixing a component A and a component B according to a mass ratio of 1: (4-6), with the component A comprising a curing agent and a first solvent in parts by weight, and the component B comprising CTBN modified epoxy resin, epoxy resin, dibutyl phthalate, polypropylene glycol diglycidyl ether, basalt fiber, high-temperature glass flake daub, white carbon black, nano silicon dioxide, a wetting dispersant and a second solvent, and end capping: soaking the end part of the tubular ceramic membrane in the end capping slurry, taking out the tubular ceramic membrane, blowing away the slurry blocked in the hole, and then heating and curing to finish the end capping of the tubular ceramic membrane. The end-capping material provided by the invention has the advantages of low viscosity, high bonding strength and better toughness, and better end capping is performed on the tubular ceramic membrane, so that the service life of the ceramic membrane is prolonged.
本申请涉及膜分离的技术领域，具体公开了一种管式陶瓷膜的封端方法，包括以下步骤：制备封端浆料：以1:（4‑6）的质量比混合A组分和B组分，以重量分数计，A组分包括固化剂和第一溶剂；B组分包括CTBN改性环氧树脂、环氧树脂、邻苯二甲酸二丁酯、聚丙二醇二缩水甘油醚、玄武岩纤维、高温玻璃鳞片胶泥、白炭黑、纳米二氧化硅、润湿分散剂和第二溶剂；封端：将管式陶瓷膜的端部置于上述封端浆料中浸泡，取出后吹去堵在孔内的浆料，然后升温，固化，完成对管式陶瓷膜的封端。本申请具有提供低粘度且高粘结强度且韧性更好的封端料，对管式陶瓷膜更好的封端，以提高陶瓷膜的使用寿命。
