The advantages of PVC flooring materials
2.pvc elastic floor material is the best choice for international official basketball courts, including basketball. Only pvc sports flooring may be used to lay internationally recognized badminton courts, table tennis, volleyball, handball, etc.
3. Compared with hard ground, it has good safety, shock absorption and rebound, and its own sportiness is fully exerted.
4. Durable, beautiful, and a variety of colors and styles to choose from.
Pvc flooring material structure precision 1. This product consists of pvc wear layer, glass fiber reinforced layer and pvc foaming buffer layer.
2.100% pure pvc wear-resistant layer, anti-aging and fastening technology, wear resistance, pressure, combined life of up to 15 years.
3. The glass fiber reinforced layer plays a role in stabilizing the site size and prolonging the service life, so that the floor does not shrink, the performance is more stable, and the athletes play a better level.
4. Closed-type PVC foam cushioning material, such as air-cushion structure, provides absolute safety, rebound resilience and standard vibration absorption, and the vibration absorption rate reaches 30%~50%.
5. The bottom of pvc foaming buffer layer adopts "honeycomb" pattern processing, reasonable weight can discharge the air inside when the site is spread, form vacuum, have more adhesion, and have more stability during exercise.
Pvc coil flooring construction plan Basic requirements: Construction ground floor must be clean, long-lasting dry, and no cracks. Ground leveling, concrete ground moisture content shall not exceed 2.5%, gypsum ground water content shall not exceed 0.5%.
Fixed paving: Before the floor is laid, the floor must be cleaned. The floor is laid out in advance and laid on the floor for 24 hours or more and the on-site temperature is not lower than 15°C. After the floor is restored, the two ends of the floor should be kept at 5 cm before bonding. The unrolled floor is rolled up approximately halfway, then the double-sided tape is first glued to the ground (bonding only the joints of the floor) and the floor is slowly merged.
Movable installation: The floor and the floor are bonded together with a special connecting band, and the floor is not bonded to the ground to facilitate future movement.
Welding heat welding method: Before the floor welding, use manual or machine to slot the floor surface. The slot must be cleaned. The temperature during hot welding should not be lower than 500°C. The welding can be fully automatic or manual. Before the formal welding, first use a small section of wire to test the proper temperature and speed during welding. After the weld is cooled, remove the excess wire in two steps. Use a crescent shovel to shovel off half of the protruding part of the wire first. After the wire has cooled sufficiently, remove the rest.

Precautions for use of graphite electrodes
1. According to the capacity of the electric furnace and the load of transformer, the grade and diameter of the electrode are suitable
2. When loading the electric furnace, the bulk charge shall be placed in the bottom of the furnace so as not to break the electrode. In the process of smelting, the lime should not be conductive. Large masses of objects are concentrated directly below the electrode, otherwise it will affect the electrode and even cause the electrode to break.
3. Attention should be paid to the position of the furnace cover. If the furnace cover is offset, the cover of the furnace will be blown on the lifting electrode, causing the electrode to be damaged.
4. When connecting the electrode, if the defect of joint bolt is found, the connection should be made after replacement
5. After the electrodes are connected, if there is a gap in the connection surface, it is important to find out the reason
6. The electrode should be used vertically.
7. The electrode holder shall be sandwiched between the upper and lower levels of the top electrode, and shall not be sandwiched between the warning line and the middle electrode. Otherwise, the electrode column is easily broken
8. The raw materials and production techniques of different manufacturers may vary. The physical and chemical properties of the electrode are also different, and it is recommended that the joints and electrodes produced by different manufacturers should not be used in a different way.
