Plastic boards are divided into high-pressure PE boards and low-pressure PE boards. By adding anti-ultraviolet agents, the anti-aging properties can be improved and the outdoor service life can be extended. It has the characteristics of high toughness, tensile resistance and good wear resistance. It has a wide range of applications in the fields of chemicals, clothing, packaging, electronics, food, etc. Plastic panels are widely used in the production of hoarding panels for ice hockey rinks, dump truck compartment panels and earthmoving compartment panels in coal mining areas, etc. Plastic panels are odorless and non-toxic. It feels like wax, has excellent low temperature resistance, good chemical stability, can withstand most acids and alkalis, and is not resistant to oxidizing acids), is insoluble in general solvents at room temperature, has low water absorption, and has excellent electrical insulation properties; density Low; good toughness); good stretchability; good electrical and dielectric insulation; low water absorption; low water vapor permeability; good chemical stability; tensile strength; non-toxic and harmless. Solving the problems required by the processing industry. Plastic plates are divided into high-pressure PE plates and low-pressure PE plates, which have the characteristics of high toughness, tensile resistance and good wear resistance. It has a wide range of applications in the fields of chemicals, clothing, packaging, electronics, food, etc. It can be filled, flame-retardant, modified, and the surface can be embossed and frosted. The traditional mechanical processing method, the drill bit and other machinery directly act on the plastic workpiece, it is easy to deform the plastic workpiece, and it will form burrs at the processing place, and some processing is required. The precision is often not up to the requirement and the processing speed is relatively slow. . The application of laser technology to plastic processing can avoid the above-mentioned drawbacks, greatly speed up the research and development of new plastic products, and enable plastic applications to enter the 'high, precise, and cutting-edge' field.

The laser is to focus the light energy through the laser to form a laser beam, and accurately send the huge energy to a very small area, so as to weld, cut, engrave, and engrave various materials including plastics. Marking, drilling and other processing. In order to improve the workability of concrete and reduce the water-cement ratio, the PE plastic board is appropriately mixed with superplasticizers, and the dosage is controlled at 0.8% of the amount of cement; in order to reduce the heat of hydration of the concrete, fly ash can be appropriately added. Commercial concrete is used for transportation of subway tunnel structure concrete, which is transported by concrete trucks and pumped and poured. Due to the influence of traffic control, the subway concrete pouring construction is generally carried out at night, and the amount of one-time pouring is large. The pump pipes are transported vertically through the shaft, with many elbows, and the transportation distance is generally longer. The plastic board is added with anti-ultraviolet agent. It can improve the aging resistance and extend the outdoor service life. Plastic board is a kind of high crystallinity, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. The plastic board has excellent resistance to most domestic and industrial chemicals. Certain types of chemicals can cause chemical corrosion.
