ã€China Aluminum Industry Network】 Heat insulation aluminum alloy building profile is a new construction material that meets building energy-saving requirements. It is a compound with heat insulation and cold insulation function made of aluminum alloy building profiles with low thermal conductivity and non-metallic materials. material. In addition to its characteristics as a building profile, it also has excellent insulation properties and sound insulation properties.
1Injection and injection of broken parts The technique of pouring and breaking bridges is to inject the liquid thermal insulation material into the aluminum alloy profile insulation tank and solidify it, cut off the temporary connecting bridge in the aluminum alloy profile thermal insulation slot to break the metal connection, and pass the thermal insulation material. The two parts of the aluminum alloy profile are combined in a combined manner.
Production Note:
1 The pouring of heat-insulating glue into the super-cooled profiles can lead to cracking of the heat-insulated material during the subsequent processing. Therefore, the temperature of the aluminum material should be kept higher than 18°C ​​during pouring.
2 There should be no dust, grease and dirt on the surface of the thermal insulation tank, which will have a greater negative impact on its adhesive strength.
3 When the bridge is broken, the blade thickness is 75%—100% of the required width of the bridge. The temporary bridge of the aluminum profile must be completely cut off, and the depth of the heat-insulating glue to be cut off should not exceed 1 mm. When the metal is temporarily connected to the bridge, the incision is prevented from being too deep.
2 wear articles wear strips of heat insulation aluminum alloy profiles is a good insulation properties of high density polyamide PA66 strips, or PVC hard plastic strips rolled through the strip, so that aluminum and plastic into one .
The following takes the actual case in the production process to analyze the matters needing attention.
Case 1: When the tooth was opened, the material level exceeded the standard and did not notice that all batch A or B teeth were opened. When the finished product heat insulation material was found, it was found to have exceeded the standard and terminated. Therefore, in the production of the use of vernier caliper down the plane, the requirements for the next drawing, the team leader, quality inspectors to analyze together, the problem will not appear.
Case 2: During the process of tooth opening, the mechanical screw loosens and walks, and when the wear is found, the tooth is only found to be deep, or only after the rolling test machine is discovered that the tooth is not deep enough and the finished product performance cannot meet the requirements (24N/MM ). The following method shall be used: 10 to 20 A and B groups shall be opened first, and then the group leader shall conduct mass production after the commissioning pressure test is correct. If the teeth are too deep, the internal teeth must be removed with a saw blade. The material will not be scrapped. If the teeth are not deep enough, all the teeth must be reworked. Therefore, a small error in the opening process will cause the entire production line to stop production. Enough attention. At the same time, the opener must always pay attention to the direction of the profile, discharge carefully, adhere to two points in a straight line.
Case 3: Fan-empirical mistakes, wrong tape on the production line. The same customer has two orders with the same color, but the requirements for the strips are different. During the production process, employees use the wrong strips based on experience and memory. In order to prevent employees from committing the same mistakes, the office computer was moved to the site for checking orders at any time.
Case 4: When abnormal pressure is applied to a pressure regulator G7002A (blank), the pressure will rise upwards, the pressure will increase, and the result will be bent downward again. Several times in a row, it will not be straightened. It will have been bent. A measurement of one branch of G7002 was made. It was found that there were four wall thicknesses, and all four hundred thicknesses were separated by four thicknesses. Each of them was processed one by one and all passed. Sometimes processing heat insulation material, 0.2mm is a thickness.
Insulation aluminum alloy profile is a new type of environmentally friendly structural material. In its production process, it must be strictly in accordance with the process requirements to produce products that meet the requirements of customers and markets.
