Analysis of technical characteristics, advantages and disadvantages of PS picture frameAnalysis of technical characteristics, advantages and disadvantages of PS picture frame
PS Picture Frame Photo Frame is a fast-growing frame product in the picture frame industry, photo frame industry, picture frame industry, decorative painting industry and oil painting industry in the past decade. Since its introduction to China in 1999, it has been conservatively estimated that there are 1,200 production lines nationwide, and manufacturers are located in major cities across the country. The reason for the rapid rise of PS frame strips is that they are inextricably close to the wooden frame and the appearance simulation of the frame strips. In addition, the process of foaming lines has many natural advantages that wood lines do not have, such as lighter, not afraid of moisture, recyclability, etc., so the frames, photo frames, mirror frames, painting frames made of PS foam lines It is no wonder that decorative building materials are favored by the market.
However, because the process source of the picture frames and photo frames made by foam lines is foam plastic extrusion and thermal transfer technology, there are still some defects in the technical level of this product, so the majority of picture frame manufacturers have some confusion about the application of the product. Therefore, this article hopes to introduce the PS frame to make the general users have some understanding, and also hopes that through understanding, you can make better use of the PS frame to make exquisite, high-quality picture frames, photo frames and mirror frame products.
PS frame lines are plastic extrusion products. The plastic raw materials used are mainly recycled expandable polystyrene (abbreviated as benzene) and high-impact modified polybenzene (abbreviated as benzene). Among them, permeable benzene is the main raw material. It is drawn into a solid shape with a low foaming rate according to the mold. Benzene is mainly used for adhesion and does not foam itself. Because the above two materials are mainly recycled, the stability of the foam line will be different from batch to batch. Therefore, in order to unify the stability of raw materials, the main manufacturers generally re-granulate the purchased raw materials.
Since benzene is foamed and benzene is not foamed, the manufacturer hopes that the proportion of benzene is higher, so the cost of using raw materials is lower, but it is not possible to completely use benzene, and it must be added to maintain the stickiness of the line and Cohesive force, so that when the frame is cut and nailed, there will be no quality problems such as crispiness, peeling, and uneven cut surface. Explained in this way, when the picture frame processor encounters the above problems, it also understands the reasons for peeling and slag, and nail cracking. In fact, the lightness and weight of the picture frame and the frame are both quality problems. Too light and crisp, too heavy corner nails can not penetrate. Therefore, the PS picture frame frame is not as simple as possible. The lighter the better or the heavier the better. From a technical point of view, according to different quality recycled PS particles, the appropriate weight is different, and the general difference is around the industry standard weight. The tenth gap is around.
Secondly, for PS picture frame frame strips, all users have encountered the problem of different heights of the two frame strips when cutting the corners of the frame strips, which will cause uneven corners. This is actually determined by the PS foam line production process. After the foam line exits the mold, it needs to enter the sink to cool and form. According to the principle of thermal expansion and contraction, after the line leaves the mold, the shape must shrink. At this time, if the traction speed is If you cannot maintain a consistent uniform speed (in theory, a completely uniform speed is impossible), the line will have a problem of high and low, so the production speed of a good PS frame is relatively slow, because only relatively slow, high and low can be relatively stable, but large In order to pursue the output value of most factories, driving fast is a common phenomenon, so it is no wonder that many low-end products are more prone to high and low phenomena. According to the PS foam line production quality standard, the same box of products, the relative error of height can not exceed 50 filaments are qualified products, and exceeding this standard should be regarded as a quality problem. Therefore, when using PS lines, care should be taken not to disintegrate as much as possible, and try not to splice different boxes and frames. In the process of making a picture frame, if you notice unevenness when nailing the corners, you need to level it up, which is also a simple remedy.
Third, if the bottom of the PS foam frame is slightly concave, it is a good phenomenon. If it is convex, * is a bad product. The remedy can only be manually planed, but it will be very time-consuming and laborious.
