Method for adhesive tape treatment in production of thin film by casting machine

The invention discloses a method for adhesive tape treatment in the production of thin film by a casting machine. On the surface of a steel tape, both the temperature in a viscosity drying tunnel for polyamic acid resin solution and the wind velocity at the outlet of a nozzle are regulated to a best state, the stripping condition of thin film at the steel tape where a front drum operates is detected, the speed of the steel tape is decreased when the adhesive tape width at one or two sides of the steel tape is more than 5.0mm, the speed of the steel tape is increased when the adhesive tape width at one or two sides of the steel tape is not more than 3.0mm, and the speed of the steel tape is decreased or increased when the adhesive tape width at one or two sides of the steel tape is in a range from 3.0 to 5.0mm. The increase or decrease for the speed of the steel tape is conducted in multiple steps, and the amplitude of each adjustment is from 0.1 to 1.5m/min, which is within the normalspeed range of the steel tape. In order to keep the solvent content of a semi-finished thin film unchanged, the temperature of the drying tunnel and/or the wind velocity at the outlet of the nozzle of a plenum chamber is regulated during speed adjustment of the steel tape. The lip opening of a casting die head can also be regulated during speed adjustment of the steel tape to eliminate the adhesive tape, and the increase or decrease for the lip opening of the die head can be conducted in multiple steps as well. The method of the invention can eliminate the adhesive tape rapidly to enable the casting machine to operate normally.

Adhesive tape processing method in film production of slobbering machine

The invention discloses an adhesive tape processing method in film production of a slobbering machine. The surface of a steel tape, the viscosity of polyamic acid resin solution, temperature in a drying tunnel and air velocity at a nozzle outlet are all adjusted to the best state; the film stripping condition is detected; if the width of the adhesive tape on one side or two sides of the steel tape is greater than 5.0 mm, the current lip opening of the side or two sides of a die head is reduced; if the width of the adhesive tape on one side or two sides of the steel tape is less than or equal to 3.0 mm, the current lip opening of the side or two sides of the die head is increased; and if the width of the adhesive tape on one side or two sides of the steel tape is 3.0-5.0 mm, the current lip opening of the side or two sides of the die head is reduced or increased. The lip opening is adjusted for multiple times, and the amplitude of each adjustment is 5-12 microns, within an adjustment range of the lip opening. In order to keep the solvent content of a semi-finished product of the film unchanged, the temperature of the drying tunnel and / or the air velocity at the nozzle outlet of a static pressure box are adjusted when the lip opening is adjusted. In the speed adjustment of the steel tape, the moving speed of the steel tape also can be adjusted to eliminate the adhesive tape. Themethod can quickly eliminate the adhesive tape so that the slobbering machine operates normally.
