Acrylic panel punching is a very common process, but a lot of customers reflect a little acrylic panel once punching the plate burst. So how does it happen and what to do about it? The following Xi 'an acrylic briefly summarizes several points for your reference: 1, acrylic panel holes on the screw will appear burst, generally caused by improper operation, acrylic panel of hot and cold expansion coefficient is very large, generally is nine times of metal, so in the acrylic plate punching, should pay attention to must leave a gap for the acrylic panel expansion, play a larger hole; There is the screw when the screw is too tight will also appear burst; Also, don't get too close to the edge when making easy holes. 2, with ordinary twist drill, ground into a three-pointed shape, the middle point is slightly higher, so that the drill can drill plexiglass. Or use hand drill, drill when the force should be uniform, the pores set aside under the glass plate should be small, in order to enhance the strength of the glass. You can also put some sand on the glass to increase the friction. 3, the hole can not be scrubbed with alcohol, otherwise it is easy to burst. Choosing more high-quality acrylic plexiglass sheet is the basic guarantee to avoid the occurrence of burst

Plexiglass a kind of polymer transparent material, chemical name is polymethyl methacrylate, is made of methyl methacrylate polymerization of polymer compounds. It is an important thermoplastic developed earlier. Organic glass is divided into colorless transparent, colored transparent, pearlescent, embossed organic glass four kinds. Organic glass is widely used, not only in business, light industry, construction, chemical industry and other aspects. And organic glass production, in advertising decoration, sand table model is widely used, such as: signs, billboards, light box panel and Chinese and English letter panel. Material selection depends on the shape design, what kind of shape, what kind of plexiglass, color, variety should be repeatedly tested, so as to achieve the best effect. With good shape design, but also rely on careful processing and production, in order to become a beautiful artifact. Polymethyl methacrylate is a popular name shortened to PMMA.

1. Raw material management The storage place of rubber raw materials must be kept dry, clean, no debris, no oil; Store in a cool and ventilated place during high temperature in summer. Before all rubber materials are stored, the appearance, hardness and humidity of rubber raw materials must be checked, and recorded and archived. After confirmation, production can be carried out. Natural and synthetic rubber has a very low moisture content, such as moisture content. 1% (typical value is 0.20%~0.40%MC, some moisture content is even lower), if the moisture is too high will have a significant impact on the production and molding process. Rubber raw materials should be stored 20~25cm above the ground and 30cm above the wall. 2. Warehouse management The finished product warehouse shall be protected against moisture, mildew, lightning and pollution. When storing rubber products, they should be classified and positioned, 20~25cm from the ground, 30cm from the wall, and there are obvious classification signs. The temperature and humidity in the warehouse must meet the storage requirements. If possible, it is better to have a dehumidifier. Transparent silicone tube Store according to the product instructions of rubber parts. Avoid direct sunlight, heat, moisture and contact with solvent oil, lubricating oil and other solid materials. The storage temperature is generally between 0 and 25℃. Proper ventilation. When the outdoor temperature or humidity is higher than the indoor, it is not appropriate to open Windows for ventilation. In and out according to the principle of first in, first out. 3. Transportation management When loading container vehicles, use an appropriate amount of dry desiccant on the hooks inside the container vehicles to ensure that the tires are not affected by moisture and mildew during transportation.
