Problems solved by technology

If the dust is not eliminated, the static electricity carried by the dust will also increase the adsorption capacity of the static electricity during the film transportation process, continuously absorb the dust, increase the amount and particle size of the dust, directly affect the cleanliness of the emulsion, and cause uneven coating or Defects affecting product quality such as poor emulsion coating
Existing cleaning devices, such as those imported from West Germany, will produce secondary pollution, and require frequent replacement of dipping cleaning rollers. They are equipped with large and expensive static elimination devices, and the cleaning is not thorough enough, with high investment costs and a long service life. short

Embodiment Construction

[0023] Such as figure 1 As shown, the film cleaning method in this preferred embodiment comprises the following steps:

[0024] (1) Eliminate static electricity on the front of the film base;

[0025] (2) Blow with high-pressure strong wind to eliminate the dust on the front of the film base, and filter the dusty air;

[0026] (3) Purify the filtered air to obtain clean air, which is then blown by strong wind again;

[0027] (4) Convert one side to eliminate static electricity on the back of the film base;

[0028] (5) Blow with high-pressure strong wind to eliminate the dust on the back of the film base, and filter the air with dust;

[0029] (6) Purify the filtered air to obtain clean air, which is then blown by strong wind again.

[0030] The wind pressure P of the high-pressure strong wind is 6000Pa, the air volume H is 5000m / h, the wind temperature is about 24°C, the rheumatism is 60%, and the air cleanliness is 5000 grades.

[0031] Such as figure 2 , 3 As shown,...

Abstract

A method for cleaning film includes eliminating the electrostatic charges from the front surface of a film, blowing high-pressure wind for removing dust, filtering the air containing dust, and repeating said steps for the back surface of the film. Its apparatus is composed of two electrostatic eliminators, two cleaners and three film guiding rollers.

Description

technical field [0001] The invention relates to a film cleaning method and equipment thereof. Background technique [0002] The whole process of photosensitive material production film base from packaging, delivery, transportation to production and coating is carried out in a clean environment that cannot be sealed. In the coiling and packaging link of the film base production process, friction will occur, resulting in the existence of static electricity, so there are conditions and opportunities to absorb tiny dust in the environment, which has a great impact on the quality of coating production. Especially for high-magnification movies, tiny dust spots will become a big spot on the screen. If the dust is not eliminated, the static electricity carried by the dust will also increase the adsorption capacity of the static electricity during the film transportation process, continuously absorb the dust, increase the amount and particle size of the dust, directly affect the cle...
