Plexiglass quality judgment and avoid deformation method _ Where is the acrylic fish tank custom
The development of plexiglass in the Chinese market is relatively slow. We often see plexiglass display products, crafts or some household items. Because of the limitations of domestic processing technology, it cannot be used in the construction of schools like foreign countries. The quality of plexiglass sheets on the market is uneven, and some merchants often cut corners, or use finished plexiglass acrylic materials to make finished products and sell them at high prices. Therefore, we must know how to judge the quality of plexiglass products in order to be deceived. Didoyak Customs will tell you how to judge the quality of plexiglass products.
First, look at the transparency of plexiglass
Everyone knows that the transparency standard for plexiglass is 92%, which is more transparent than glass. The highly transparent plexiglass is also very transparent after polishing, almost the same as the surface. So we must compare the transparency of plexiglass.
Tip: Generally, the acrylic products we get from manufacturers or stores are protected paper. After tearing, the transparency of plexiglass is compared with the light. The blue and yellowish are synthesized with recycled materials and new materials. All of the plates made from new materials are very high in transparency.
Second, look at the thickness of plexiglass
People who often deal with acrylic products know that the finished products on the market generally have tolerances. Some businesses cut corners and some are inevitable errors in machine cutting.
Tip: The better the plexiglass, the smaller the tolerance of the thickness, which can be determined according to your own needs. If you are doing some crafts gifts, display stands, display supplies, this does not have to be considered. However, if you want to do some lens panels, product accessories, etc., you must determine the relevant standards in advance with the manufacturer.
Third, look at the protective glass and brand identity of the plexiglass face
Tip: Whether you are a wholesaler or a self-employed person, it is recommended that you choose a regular manufacturer to order or purchase, choose the current domestic relatively large plexiglass acrylic manufacturers, a good manufacturer in a certain area of the industry. Because the materials used by powerful manufacturers are imported raw materials and domestically produced.
If you want to maintain the high-grade appearance of acrylic products for a long time, you should regularly clean and maintain the acrylic products, but you must also know the deformation of the acrylic products in the process of processing:
1. Acrylic sheet has a heat distortion temperature of about 100 degrees and a continuous use temperature of not more than 90 degrees.
2. Avoid scratching during the process of use.
3. When installing, you must consider leaving a certain amount of expansion space.
4. When making, choose the appropriate thickness of acrylic sheet to avoid bending deformation.
When a large-sized acrylic sheet is used, the thickness is increased to prevent the sheet from sagging due to its own weight, and the thermoforming can improve the impact strength. The type of acrylic products should be made of acrylic sheet with the right weight. Don't be too thin or thick, avoid deformation caused by the bearing weight of the sheet and the product.
