A membrane washing system

Abstract

The invention provides a membrane washing system that can continuously remove fine dust, diaphragm or tainting substance that attached to the plastic membrane. The system comprises a washing part (36) that washes a mobile membrane with washing liquid; and a drying part (38) that drys the washed mobile membrane. The washing part (36) is provided such a structure that at least one side of the membrace is supplied with washing liquid while moving the membrane (12).

Description

technical field [0001] The present invention relates to the cleaning system of the film that continuously washes the dust, diaphragm and pollutants attached to the surface of the plastic film, especially relates to the film cleaning of the film used in the FPD (flat panel display) field, electrical field, optical field, etc. that require cleanliness system. Background technique. [0002] Plastic films have been widely used in various fields such as the FPD field, the electrical field, and the optical field. Plastic films used in the FDP field and the electrical field are used as components and process materials through processes such as film formation, coating, and lamination. This manufacturing process must be operated in a clean environment from beginning to end, and defects such as contamination and adhesion of impurities such as dust, fibers, and film fragments to the product, and the occurrence of physical defects such as scratches and indentations caused by these defe...

Problems solved by technology

[0003] As a solution to this problem, an adhesive roller is used to remove dust, fibers, and film fragments from the surface of the plastic film, but the effect of removing impurities due to the retransfer of dust from the adhesive roller, etc. is insufficient.

In addition, since the static electricity generated when peeling off the bonding roller remains on the plastic film, it attracts the surrounding impurities, and the effect of increasing the frequency of defects is worrying.

[0004] In addition, the operation of blowing high-pressure gas and suction to the plastic film continuously to remove dust, but there is a problem that the firmly attached dust cannot be sufficiently removed.
