【China Aluminum Network】 1. Discoloration and discoloration of aluminum-plastic panels and discoloration of aluminum-plastic panels are mainly caused by improper selection of panels. Aluminium-plastic panels are divided into indoor panels and outdoor panels. The surface coatings of the two types of boards are different, which determines their applicable different occasions. The plates used in the interior are generally coated with a resin coating. This coating cannot adapt to the harsh outdoor environment. If used outdoors, it will naturally accelerate its aging process and cause discoloration and discoloration. The surface coating of outdoor aluminum-plastic composite panels is generally made of a fluorocarbon resin coating with strong anti-aging and anti-ultraviolet resistance. This type of panel is expensive. Some construction companies deceived the owners to impersonate anti-aging and anti-corrosion high-quality fluorocarbon plates with indoor plates, and squeezed unreasonable profits. As a result, the aluminum plates used in the project were seriously discolored and discolored.

2. The plastic-opening of aluminum-plastic panels, the opening of aluminum-plastic panels and the shedding of aluminum-plastic panels are mainly due to improper selection of adhesives. As an ideal adhesive for outdoor aluminum-plastic board project, silicone rubber has unique advantages. In the past, China's silicone rubber relied heavily on imports. Its price was deterred by many people, and only those curtain wall projects that were expensive on high-rise buildings were dare to pay attention. Now, China's Zhengzhou, Guangdong, Hangzhou and other places have put into production of different brands of silicone rubber, resulting in a sharp drop in prices. Now, when buying aluminum plastic board, the seller will recommend that kind of special quick-drying glue. This glue can be used indoors and used in the outdoor where climate change is unpredictable.

3, the deformation of the surface of the aluminum-plastic plate, the cause of the deformation of the surface of the aluminum-plastic plate from the drum, and the reasons for the drumming are various. Previously in the construction, there have been such quality problems, we used to think that the quality of the plate itself; later, after a concentrated analysis of everyone found that the main problem lies in the paste of aluminum plastic plate on the substrate, followed by aluminum plastic The quality of the board itself. Dealers often provide us with the construction process of aluminum-plastic panels. The basic materials that we recommend to use are mainly high-density boards, wood boards, and the like. In fact, when these materials are used outdoors, their service life is very fragile. After being blown by the wind, sun, and rain, they will inevitably undergo deformation. Since the grass-roots materials are all deformed, why does the aluminum-plastic board as a surface layer not deform? It can be seen that the ideal outdoor base material should be rust-proofed and the angle steel and square steel pipes should be combined into a skeleton. If conditions permit, the use of aluminum profiles as skeletons is even more desirable. The cost of the skeleton made of such metal materials is not much higher than that of wood keel and high density plates, which can really guarantee the quality of the project.

4, aluminum plastic plate glue neatly spliced ​​aluminum composite panel in the decoration of the building surface, the plate generally has a certain width of the gap. For aesthetic needs, black sealants are generally filled in the gaps. In order to save time, some construction workers do not use paper tape to ensure the orderliness and rules of plastic injection. Instead, they use the protective film on the surface of the aluminum-plastic panel as a substitute. As the aluminum-plastic board cuts, the protective film will produce different degrees of tearing, so use it as a substitute for the protective tape, it is impossible to neatly gather the glue. Through the analysis of some common quality problems encountered in the processing and assembly of aluminum-plastic panel (composite aluminum panel), the measures and methods for solving the problems are proposed. This will inevitably cause the construction staff to apply aluminum-plastic composite panels when processing and installing aluminum-plastic composite panels. Common quality problems can be prevented and controlled. Aluminum-plastic composite panel is a composite material processed by a special aluminum-plastic-plastic panel production equipment with a chemically treated coated aluminum sheet as the surface material and a polyethylene plastic core material. The unique properties of the aluminum-plastic composite panel determine its wide range of uses: It can be used in building facades, curtain wall panels, renovation and refurbishment of old buildings, interior wall and ceiling decoration, advertising signs, display racks, purification and dust prevention engineering. Aluminum-plastic composite panels have been widely used in China and belong to a new type of building decoration materials.

Geogrid is divided into plastic geogrid, steel-plastic geogrid, glass fiber geogrid and polyester warp knitting polyester geogrid four categories.

Plastic grille

The tensile direction of the polymer net, which has a square or rectangular shape, can be stretched in one direction and two - way.It is extruded through extruded polymer sheets (mostly polypropylene or hdpe), and then directional stretching under heating conditions.The unidirectional tensile grille is only drawn along the length of the plate.The bidirectional tensile grille continues to stretch the grid of unidirectional stretching in a direction perpendicular to its length.

Due to the rearrangement of polymer polymers in the manufacture of plastic geogrid, the bonding force between the molecular chains is strengthened and the purpose of enhancing the strength is achieved.Its elongation rate is only 10% ~ 15% of the original plate.If the anti-aging materials such as carbon black are added to the geotextile grille, it can have good resistance to acid, alkali resistance, corrosion resistance and aging resistance.

Steel plastic earthwork grille

Steel-plastic geogrid with high-strength steel wire (or other fiber), through special processing, with polyethylene (PE), and add other additives, by extrusion compound high strength resistance to stay with it, and we have rough surface embossing, is for the high strength reinforced belt.From this, the single belt is prepared or sandwiched by a certain spacing, and the welding technology of special strengthening adhesion is welded to the contact point, and it is a reinforced soil grate.
