Example Embodiment

[0020] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0021] refer to figure 1 , the present embodiment provides a novel dipping process, the steps of which include:

[0022] 1) Workpiece pretreatment: the workpiece pretreatment in the step 1 includes surface pretreatment and overall pretreatment, wherein the overall pretreatment is a stress removal process, and the deburring and oil removal are set after the stress removal step. In the embodiment: the first deburring treatment is carried out, and the deburring treatment is carried out by means of steel ball scouring. In the step of removing burrs, the diameter of the steel ball is 0.5-1mm, and the speed of scouring on the workpiece is between 0.5-2m / s , when setting, it is set as 1m / s. With the wear of the steel ball, the speed of the steel ball ejection should be adjusted in time, so as to ensure the effect of removing burrs;

Abstract

The invention discloses a novel plastic dipping technology. The novel plastic dipping technology improves the situation that in the prior art, when powder plastic dipping is adopted for plastic dipping, it is difficult to guarantee that the plastic dipping thickness of each face is the same, so that a part of positions are thick, and a part of areas are thin. According to the novel plastic dipping technology, a preheated workpiece is immersed into epoxy resin powder in a fluidized state, so that the epoxy resin powder is adhered to the surface of the workpiece, when the epoxy resin powder is adhered to the workpiece, the epoxy resin powder melts and is adhered to the surface of the workpiece, the epoxy resin powder is taken out from the epoxy resin powder in the fluidized state after 3 seconds, and high-pressure air is blown out by using an air compressor, and the unmelted resin powder is blown off, so that the same thickness of the plastic dipping layer on each surface of the workpiece can be effectively ensured, and the coating quality is effectively ensured and improved.

Description

technical field [0001] The invention relates to the field of plastic dipping, in particular to a novel plastic dipping process. Background technique [0002] Plastic dipping is to spray plastic powder evenly on the metal by heating the metal to form a layer of plastic film, or heat the dipping liquid into the metal parts to cool it and then cover the metal surface with plastic. This process has the characteristics of no need for molds, low processing cost, easy forming, and can process various shapes, etc., and is widely used. However, the products of the guardrail netting are all powder dipping; according to whether heating is required, it can be divided into hot dipping and cold dipping, and according to the raw materials of dipping, it can be divided into liquid dipping and powder dipping. [0003] Currently, Chinese Patent No.: CN202010429091.6 discloses an anti-corrosion plastic dipping process for metal profiles, including a high-temperature box device, a PE powder bo...
