An online fluorination device for plastic containers

Abstract

The invention belongs to the technical field of fluorination equipment and discloses an online fluorination device for plastic containers. The online fluorination device for plastic containers includes a fluorination box, a sealed box door installed on the front of the fluorination box, a vacuum pump, and a gas generator. It communicates with the inside of the fluorination tank through the connecting pipe one. The online fluorination device for plastic containers is inserted into the container through the design of the positioning branch pipe and the support wire, and is supported by the container inside the container. The fluorinated reaction gas is released from the positioning branch pipe, and reacts preferentially with the inner wall of the container, and utilizes the impact of the gas The force and the elasticity of the support wire can help the container jump during the air intake process, and the support position of the support wire can be changed to ensure the uniform contact between the fluorinated gas and the inner wall of the container, without blind spots, and to avoid the fluorination effect of the support points of the components in the existing equipment bad question.

Description

technical field [0001] The invention relates to the technical field of fluorination equipment, in particular to an online fluorination device for plastic containers. Background technique [0002] The use performance of plastic products has a great relationship with its surface characteristics. Therefore, modifying the surface can not only improve the use performance of the product, but also reduce the production cost. Surface fluorination treatment technology is a kind of surface modification technology. , After fluorinated plastic, the surface has high surface activity, high chemical and heat resistance stability, which can greatly improve the oil resistance and oil repellency of the product. [0003] For the fluorination processing of plastic containers, since the container contains inner and outer walls, the uniformity of contact between the inner wall of the container and the gas should be considered during the fluorination process. On the other hand, the high-speed flow...

Problems solved by technology

[0003] For the fluorination processing of plastic containers, since the container contains inner and outer walls, the uniformity of contact between the inner wall of the container and the gas should be considered during the fluorination process. On the other hand, the high-speed flow of gas in the equipment must be ensured to ensure The fluorination reaction is fully carried out. When the existing fluorination device is processing parts, the parts are fixed and placed, and the gas flow is driven by external power, so it is difficult to target the inner wall of the container. On the other hand, the power of the outer wall to drive the gas flow requires additional energy, and The sealing problem caused by external drive needs to be considered
