Embodiment 1
[0030] Step 1. Wipe the opposite surfaces of the core die with a cleaning agent. The cleaning agent is metal cleaner with the product number Q / YS.904 (Yishun brand) produced by Guangzhou Yishun Chemical Co., Ltd.
[0031] Step 2. Heat the solution to 50°C, soak a pure cotton cloth with a thickness of 0.5cm into the solution, and cover the pure cotton cloth on the opposite surface of the core die, and put it at a temperature of 35°C. Remove the pure cotton cloth after 40 minutes.
[0032] Step 3. Use a brush to evenly coat this solution on the opposite surface of the core die in step 2, and place the core die in an oven for baking. Bake for 10 minutes.
[0033] Step 4. Repeat steps 2 and 3 three times to obtain a core die that can improve the surface finish of the pipe.
[0034] The coating method in any one of embodiment 2-embodiment 9 is the same as embodiment 1 except that the parameters in table 1 and table 2 are different.
[0035] 3. Test results:

Abstract
The invention discloses a method for improving the gloss of pipes. Firstly, a solution is heated to the temperature of 50-60 DEG C. Secondly, pure cotton cloth is soaked in the solution, and a core opening mould is covered with the pure cotton cloth. At the temperature, on the one hand, the solution can be promoted to soak into the metal surface of the core opening mould stably; on the other hand, the solution is prevented from evaporating too soon. The metal surface of the core opening mould can be sufficiently soaked in the solution in the environment at the temperature of 35-40 DEG C after 40-60 min. Finally, the metal surface of the core opening mould is coated with the solution evenly, and then the core opening mould is put in an oven at the temperature of 90-120 DEG C. At the temperature, high-strength chemical bonds can be effectively promoted to form on the contact surface when the solution makes contact with the metal surface of the core opening mould, and the solution is firmly attached to the core opening mould and does not fall off. By means of the scheme, the problems of high roughness and low gloss of pipes in the prior art are solved, and the problems of complex operation and low production efficiency due to the fact that corresponding core opening moulds need to be replaced according to the different models of pipes to be produced are solved.
Description
technical field [0001] The invention relates to the technical field of pipe processing, in particular to a method for improving the glossiness of pipes. Background technique [0002] During the production and processing of pipes, the pipe raw materials need to be extruded from the extruder. The output end of the extruder is equipped with a core die. The core die includes a core die and a die. The die is located outside the core die. A space for pipes to pass is formed between the two. [0003] The traditional core die is made of metal in order to ensure its own strength or avoid the chemical reaction between the pipe and the core die. Because the temperature of the pipe in the extruder is very high, the plasticity of the pipe is strong. When it is made of metal During the contact process of the core die, the surface of the pipe will have a certain degree of adhesion with the metal surface, so that the roughness of the inner and outer surfaces of the pipe will increase and t...
