What should I do if the Boeing film shrinks? If the Boeing film shrinks, there is no other remedy, and it is necessary to replace the high-quality Boeing film and repost it.
The main reason for the shrinkage of Boeing film is the quality of the product itself, because the thickness of many Boeing films on the market is as low as 0.09mm, in order to save costs, the calcium powder content exceeds 40% span> the above base film, this will make the Boeing film have poor tensile properties, easy to fold white, and prone to reverse roll shrinkage after pasting. Secondly, the shrinkage of the Boeing film is also related to the construction, because there is thermal expansion and cold contraction. If it is operated in a particularly hot or cold temperature environment, it will easily cause the Boeing film to shrink or expand after the film is applied, thus affecting the filming effect.
How to choose high-quality Boeing film?
High-quality Boeing film can be visually identified from the thickness, high-quality Boeing film can obviously feel thick and flexible in the hand, while inferior Boeing film is thin and lighter. If there is a tool, it can also be measured with the help of a tool, such as a thickness gauge. Choose big brands from big manufacturers, Langmei and Chengxing Boeing film are thickened design, and the material is the bottom film with no calcium powder or calcium powder content less than 5%, the products produced in this way can guarantee The product has good tensile properties, it will not fold when it is pasted, and it will not shrink after pasting.
The adhesive performance of Boeing film is also very important, which can be analyzed by three indicators: initial viscosity, the adhesive force of the glue that has not been fully cured; stickiness, the ability to resist displacement after pasting; cohesion, the mutual connection force between material molecules . The viscosity of Boeing film is related to the adhesive used. The higher the solid content, the better the viscosity. Langmei and Chengxing use environmentally friendly glue with a solid content of 60, while the solid content of ordinary glues on the market is lower than >50.
Finally, when choosing a Boeing film, it is recommended to choose the back of the air guide groove with a grid shape. When pasting, the air can be discharged along the air guide groove, and it is not easy to generate bubbles. In addition, there are many fake Boeing films on the market that are flooding the market. We hereby remind consumers to choose products with the brand logo on the backing paper and the regular factory brand logo on the carton. If you buy a bottom without any logo Products made of paper or blank cartons are likely to be counterfeit and shoddy products, and everyone should be cautious in purchasing!
To sum up, to solve the problem of Boeing film shrinkage, you can choose a suitable weather during construction. The most important thing is to choose high-quality Boeing film, so as to better avoid Boeing film shrinkage.
