The heat-insulating aluminum alloy building profile is a new construction material that meets the building energy-saving requirements. It is a composite material with heat insulation and cold insulation function made by connecting aluminum alloy building profiles with low thermal conductivity non-metallic materials. In addition to its characteristics as a building profile, it also has excellent insulation properties and sound insulation properties.
1 Injection Note
Pouring broken bridge technology refers to injecting the liquid thermal insulation material into the aluminum alloy heat insulation tank and solidifying, cutting off the temporary connecting bridge in the aluminum alloy heat insulating tank to break the metal connection, and breaking the aluminum alloy material through the heat insulating material. The combination of open two parts combined.
Production Note:
1 Pouring insulation glue into super-cooled profiles can lead to cracking of the heat-insulating profile during subsequent processing. Therefore, the aluminum temperature should be kept above 18°C ​​during pouring.
2 The surface of the thermal insulation tank should be free of dust, grease and dirt, which will have a greater negative impact on its adhesion.
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 strip type heat-insulating aluminum alloy profiles are made of high-density heat-insulating polyamide PA66 strips, or PVC rigid plastic strips rolled through the strips to form aluminum and plastic.
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 it is not found that the tooth is deep enough after the rolling test machine. The performance of the finished product 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, and the pressure will increase. The result will be bent downward again. It will appear several times in a row, and it will not be straightened. It will have been bent. One branch of G7002 was measured a number of times, and it was found that there were four wall thicknesses, and all four hundred thicknesses were separated by four thicknesses, 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.
