Problems solved by technology

Certain polymer raw materials, for example also with bulky framework structures, can undergo severe structural distortions during curing, so that even the structural and functional integrity of robust filter materials cannot avoid these effects
[0006] Although technological advances have led to the development of polymeric raw materials - such as fiberglass-polymer composites - tha

Embodiment Construction

[0018] The present invention generally provides a two-step process for making a substantially planar filter plate comprising a substantially planar polymeric frame in which substantially planar filter material is embedded and fixedly mounted.

[0019] The two-step process is implemented to accommodate the structural variability of the materials used so as to reduce the undesirable and undesirable deformation of the embedded substantially flat filter material, thereby resulting in a manufactured product with less bending, warping, convexity, etc. Out of other deformations, if any. Such deformation may have an adverse effect on the functionality, effectiveness and / or longevity of the resulting filter plate. The method is robust and can be implemented to obtain relatively high yields.

[0020] The steps of the two-step embedding method are schematically shown in Figures 2a-2c.

[0021] First, as shown in Figure 2a, the outer first portion 12 of the substantially planar polymer ...

Abstract

A method is disclosed for making a substantially flat filter plate comprising a substantially flat polymer, preferably thermoplastic, frame and substantially flat filter material seated fixedly therein. The method is characterized by its reduced exposure of the filter material to adverse mechanical stresses resultant of polymeric frame formation and curing. Toward such end, the substantially flat polymeric frame is formed in at least two separate steps, in the course of which said substantially flat filter material is incorporated. The portion formed first serves as a mechanical restraint, insulating the later incorporated filter material from any propensity of the second ''embedding'' portion to shrink or otherwise warp during its formation.

Description

[0001] Related Application Cross Reference [0002] This application is a divisional application of US Application Serial No. 10 / 870,802, filed June 17, 2004, which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates generally to methods of making composite filter plates, and in particular to methods of making substantially planar filter plates comprising a thermoplastic frame and filter material fixedly embedded in the frame, and reduces mechanical The effect of stress on filter materials. Background technique [0004] Filter plates are well known. Their various structures, applications and functions are numerous. A basic configuration that has been widely used in the manufacture of, for example, filter presses, normal flow filter discs, electrodeionization devices, porous plates, and tangential flow filtration devices, consisting of a substantially flat The structure of the filter material.
