Surface activation treatment device

Abstract

The invention provides a surface activation treatment device, which comprises a shell, a reaction device and a sealing device, wherein the shell comprises an inner side wall and a bottom wall; a base plate is fixedly arranged on the inner side wall; a shaft hole is formed on the bottom wall; one end of the reaction device is sealed by a bottom plate, and a rotating shaft is vertically extended from the bottom plate; the reaction device is accommodated in the shell, and the rotating shaft is extended out of the shaft hole; the reaction device comprises an outer barrel, an inner barrel and an ultraviolet light lamp tube; the outer barrel and the inner barrel are fixedly arranged on the bottom plate, and the inner barrel is accommodated in the outer barrel; a lamp tube hole for accommodating the ultraviolet light lamp tube is formed in the outer barrel; a first space is formed between the outer barrel and the inner barrel; a second space is formed by enclosing the inner barrel; the sealing device comprises a cover body which is used for sealing the first space and the second space and is rotated relative to the shell, a first air inlet pipe which is communicated with the first space and a second air inlet pipe which is communicated with the second space; and the side wall of the outer barrel is provided with a first nozzle which is communicated with the first space, a second nozzle which is communicated with the second space and a light outlet hole which is communicated with the ultraviolet light lamp tube.

Description

technical field [0001] The invention relates to a surface activation treatment device. Background technique [0002] Generally, the surface tension of polymer plastics is extremely low, and the interface adhesion is poor. For example, the surface of PET, PTFE, PC and other plastics usually needs to undergo surface pretreatment before processing to change the interface properties to improve the bonding force of the plastic surface. [0003] Traditional treatment methods include chemical method, plasma method, corona method and ultraviolet light irradiation method. The chemical method has concerns about waste liquid in environmental protection, so it is seldom used. The advantage of the plasma method is that different purposes can be achieved by using different gases, and the effect is good. The disadvantage is that it must be processed under vacuum and low pressure. The process of vacuuming and breaking the vacuum is time-consuming, and it is not easy to achieve continuity. ...

Problems solved by technology

The advantage of the plasma method is that different purposes can be achieved by using different gases, and the effect is good. The disadvantage is that it must be processed under vacuum and low pressure. The process of vacuuming and breaking the vacuum is time-consuming, and it is not easy to achieve continuity. processing, and the higher cost of equipment is also its disadvantage

The advantage of the corona method is that the method is simple, it can be processed under atmospheric pressure, and the equipment cost is low; the disadvantage is that the effect after the treatment is not very good, and it only has a certain effect on some specific objects. If the parameters of the equipment are not adjusted properly, will destroy the object itself

The advantage of ultraviolet irradiation method is that continuous treatment can be carried out under atmospheric pressure, but only a single treatment can be performed on the surface of the plastic, which cannot meet the requirements of diversity
