Abstract

The invention discloses a manufacturing method of a microporous membrane sinter filter element, is applicable to mounting and assembly occasions of combined type water purifiers and belongs to the technical field of water resource purification. Micropores of the microporous membrane sinter filter element manufactured through the method are formed through pure-physical hot melt binding instead of a chemical reaction; and the method adopts the principle that during the heating and sintering process of a main material, after being bonded with an auxiliary material during the melting process, the main material shrinks in the following cooling process to form three-dimensional space clearances, and the micropores are related to the main material and the auxiliary material in shapes and particle sizes. The manufacturing method has the advantages of simplicity and convenience in process molding, comprehensive formula, accuracy in precision control, reliable performance and low manufacturing cost.

Description

technical field [0001] The invention relates to a drinking water purifier filter element, in particular to a production method of a microporous membrane sintered filter element, which is suitable for combined installation of combined water purifiers and belongs to the technical field of water resource purification. Background technique [0002] At present, with the rapid development of society and the improvement of people's living standards, various drinking water purifiers have entered people's lives one after another. The combined water purifier is a simple structure, easy installation, obvious water purification effect, and popular Tall new drinking water filter. This water purifier all utilizes tap water as a water source, and adopts joints and connecting hoses to combine filter elements of different filter materials into a drinking water purifier. In this drinking water purifier, the filter element is the core component, and it is used in a large amount. The general d...
