1, it is recommended to choose low-temperature tape to complete the adhesive application in winter. The ability of this type of tape to maintain molecular motion at lower temperatures ensures low temperature performance. In addition, it can also be improved from the aspects of storage, construction and maintenance conditions to ensure the winter performance of pressure-sensitive adhesive products.
2. Install with cable ties. You can fix the two corners on one side first, then go to the other side, and fix the other two corners with the tight point.At this time, it is necessary to let the cloth eat the force, generally installed with cable ties, so that it is convenient to pull tight and flat.
3, the abnormal sound in the car in winter is mainly due to the principle of some plastic parts using thermal expansion and cold contraction, resulting in gaps between the connections, resulting in a sound, the temperature in the car is high after there is no.
4, if the plastic products in the cold and hard when the abnormal sound, you can pad on the rubber pad or paper, and 3M adhesive. In this case, the rubber pad can effectively reduce the friction between plastic products, thereby reducing abnormal noise. If the rubber pad can not solve the abnormal sound problem, it may be due to the loosening of some screws or fastenersGreetings. At this time, these accessories need to be returned to the position.
5, if the abnormal sound caused by the cold and hard plastic products can be solved by some rubber pads or paper pads, it is best to stick some 3m glue. It is recommended not to remove the interior if you can. If the pad cannot be solved, it may be that some screws or buckles are loose, and it can only be disassembled for homing.
The die-cutting performance of the sticker label depends on the type of adhesive used. Acrylic waterBecause of its small cohesion, the latex usually has a good die-cutting effect. Labels using this type of adhesive have relatively low requirements for die cutting tools and the environment. Therefore, under the appropriate conditions, acrylic water-based latex can ensure the die-cutting quality.
In addition, hot melt adhesive has higher requirements for the processing environment, because the activity of hot melt adhesive is weak at low temperature, and the binding force between the adhesive surface and the bottom paper is too small during waste discharge, which is easy to cause "flying mark".
If the problem of die-cutting is not repeated regularly, then the problem may be due to the accuracy of the machine gear, the running tension of the material, and the die-cuttingCaused by lack of pressure. In this case, it is necessary to check the running tension of the material and adjust the die cutting pressure to solve. Die-cutting overflow refers to the label die-cutting process after processing, the label edge overflow glue, it is a common defect of self-adhesive products.
Causes of die cutting "flying mark" are: material release force is too low (temperature is too low), self-adhesive material surface layer and the binding force of the bottom paper is called release force. If the release force of the self-adhesive material is too low, it is likely to lead to the "flying mark" in the process of die-cutting. It should be noted here that the release force of many self-adhesive materials changes under the influence of temperature, in generalAs the temperature increases, the release force increases and vice versa.
The label is lifted with the waste side, and it is easy to have the label lifted by the waste side when the die cutter does not completely cut through the surface layer of the self-adhesive material. Die-cutting is the most common problem in the die-cutting process of self-adhesive materials, and it is relatively simple to solve, just replace the damaged blade or adjust the die-cutting pressure can be solved. It can be solved by replacing the damaged blade or adjusting the die cutting pressure.
Problem 1: Accuracy of the die cutting knife When the die cutting knife fails to penetrate the whole layer of the self-adhesive paper, the problem may appear. Uncut tissue is easy>
2, AVIC lithium die-cutting position responsibility is: according to the production plan to complete the daily production capacity of lithium die-cutting machine. Independently analyze and solve quality anomalies in die cutting process, optimize waste discharge and improve efficiency. Responsible for machine daily maintenance.
3, AVIC lithium cutting stack post delivery post is to complete the daily production capacity of lithium die-cutting machine. Because the responsibility of AVIC lithium battery cutting position is to complete the daily production capacity of lithium battery die-cutting machine according to the production plan, independently analyze and solve the quality anomalies in the die-cutting process, optimize waste discharge and improve efficiency. Therefore, AVIC lithium cutting stack post delivery post is to complete the daily production capacity of lithium die-cutting machine.
