Problems solved by technology

[0003] The present invention aims to solve the problem that the manufacturing method of the composite filter material in the prior art is likely to cause misalignment between the paper base and the composite base material, produce wrinkles and air cavities, affect the filtering effect, and cause glue breaking and degumming due to poor glue sizing methods. , make the composite filter material invalid, and creases are prone to affect the use during the winding process. It provides a precise positioning between the paper base and the composite substrate, no wrinkles and air cavities, unique sizing and repressing methods, and composite Sizing and compounding method of composite filter material with better effect, more convenient winding and longer service life

Embodiment Construction

[0032] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0033] Such as figure 1 , 2 , 3, 4, 5, 6, 7, 8, and 9, a compound method for sizing a composite filter material, comprising the following steps:

[0034] a) The composite substrate is unwound by the control of the unwinding motor 4, the unwinding adjustment roller 5 and the unwinding oil cylinder 6;

[0035] b) While the composite substrate is unwinding, the photoelectric deviation correction device is used for displacement correction;

[0036] b') Perform tension detection on the composite substrate, and adjust the speed and torque of the motor through the change of the tension signal;

[0037] c) Unwind the paper base in the same manner as step a);

[0038] d) While the paper base is unwinding, the photoelectric deviation correction device is used for displacement correction;

[0039] d') Perfor...

Abstract

The invention relates to the technical field of composite filter material manufacturing methods, and discloses a sizing and compounding method of a composite filter material, which comprises the steps of unwinding, deviation rectification, tension detection, hot melt adhesive spraying, compounding and compacting, winding and the like. The sizing and compounding method of the composite filter material provided by the invention has the beneficial effects that a paper base and the composite base material are accurately positioned, wrinkles and air cavities are not generated, the sizing and re-pressing method is unique, the compounding effect is better, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of manufacturing methods of composite filter materials, in particular to a method for sizing and compounding composite filter materials. Background technique [0002] Composite filter material is composed of paper base and composite base material through adhesive hot pressing, and has various filtration properties of paper base and composite base material, and can achieve the effect of gradient filtration. Paper base and composite base material are bonded In the process of compounding, if there is no correct method, it is easy to cause misalignment between the paper base and the composite substrate, resulting in wrinkles and air cavities, which will affect the filtering effect. Composite filter material failure, for example, Chinese patent authorization announcement number: CN105169962B, authorization announcement date May 24, 2017, the name of the invention is a method for preparing nanofiltration membranes...
