Picture frame accessories have molding and glass, hanger, clips, and others
Frame Moulding
It is made of various woods, such as paulownia, white wood, nanmu, pine and so on. The structure of the common modern simple wooden frame on the market is mainly flat wood.
There are two main uses of wooden frames:
1. Make decorative materials, such as decorative materials for suspended ceilings. It can also be used for walls and doors and windows.
2. Make the outer packaging of items, such as the frame of the painting, the frame of the photo, the frame of the mirror, and so on. It has a wide range of uses.
Resin
Resin photo frame uses resin as the main raw material, which is a non-toxic and environmentally friendly chemical raw material. The finished product has the strength of metal and is also called FRP. The resin raw material is in liquid form during production, has very good fluidity and is easy to form. It is the only material on the market that can produce high-strength carved products.
Aluminum alloy
The surface color of the aluminum alloy photo frame is processed by electroplating technology, and the colors are frosted, bright sandblasted, champagne sandblasted, and bright silver.
Picture frame glass
The glass in the photo frame is basically made of plexiglass. Plexiglass is a popular name, abbreviated as PMMA. The chemical name of this transparent polymer material is polymethyl methacrylate, which is a polymer compound formed by the polymerization of methyl methacrylate.
The characteristics of plexiglass:
① Highly transparent. Plexiglass is currently the most excellent polymer transparent material, with a light transmittance of 92%, which is higher than that of glass. The tube of the sun lamp called the artificial little sun is made of quartz, because quartz can completely transmit ultraviolet rays. Ordinary glass can only transmit 0.6% of ultraviolet rays, but plexiglass can transmit 73%.
②High mechanical strength. The relative molecular mass of plexiglass is about 2 million. It is a long-chain polymer compound, and the chains that form the molecules are very soft. Therefore, the strength of plexiglass is relatively high, and its tensile and impact resistance are 7- higher than that of ordinary glass. 18 times. There is a kind of plexiglass that has been heated and stretched, in which the molecular chains are arranged in a very orderly manner, which significantly improves the toughness of the material. Use nails to penetrate this plexiglass, even if the nail penetrates, there will be no cracks on the plexiglass. This kind of plexiglass will not break into fragments after being penetrated by a bullet. Therefore, the stretched plexiglass can be used as bulletproof glass, and also as a cockpit cover on military aircraft.
③Light weight. The density of plexiglass is 1.18g/cm3; the weight of a material of the same size is only half that of ordinary glass, and 43% of metallic aluminum (belonging to light metal).
④Easy to process. Plexiglass can not only be cut with a lathe and drilled with a drill, but also can be bonded into various shapes with acetone, chloroform, etc., and can also be processed into airplanes by blow molding, injection, extrusion and other plastic molding methods. Cockpit covers are as small as dentures and dental trays.
