The main advantages of imported plasma arcs compared to domestic plasma arcs are: a. No dross, large range of cutting speeds, and good quality of cuts; b. Cutting speed can be increased by 30% at the same power source power; c. The problem is that the cut workpiece has good welding and processing properties.
The long-life oxygen plasma arc cutting technology fundamentally overcomes the shortcomings of the short life of electrodes and nozzles in the past oxygen plasma arc cutting process, and enables the oxygen plasma arc cutting to greatly reduce the cost on the basis of high-quality and high-speed, for those Companies with large demand for steel plate cutting opened up a new world. In the past 10 years, due to the increase in the total shipbuilding volume and the shortening of the construction period, the steel plate cutting workload has risen sharply. Therefore, many domestic backbone shipbuilding companies and local shipyards have purchased large CNC cutting machines equipped with long-life oxygen plasma cutting systems. To cut the largest medium-thickness steel plate in the shipbuilding industry, the effect is significant, which also prompted people to gradually reach a consensus when selecting the type, that is, long-lived oxygen plasma cutting machine is currently the best applicable shipyard model .
Another important reason why the long-lived oxygen plasma arc cutting technology can be rapidly applied in China's shipbuilding industry in the near future is due to the considerable economic benefits brought by its use. First of all, using CNC plasma cutting, people can very quickly and easily complete the cutting task of stainless steel, aluminum, copper, composite plates and complex parts that cannot be performed by CNC flame cutting, and its economical efficiency is superior to other mechanical processing methods.

There are many grades of PVC. The viscosity or K value commonly used in the industry indicates the average molecular weight (or average degree of polymerization) of PVC, that is, the length of the PVC molecular chain, which determines the grade of the resin and the corresponding processing parameters. The molecular weight of the resin is related to the physical and mechanical properties of the product.
PVC Resin is a kind of non-crystalline linear polymer compound. The larger the relative molecular mass, the higher the viscosity, the higher the molecular weight, and the higher the tensile strength, impact strength, and elastic modulus of the product, but the flow of the resin melt Decline in sex and plasticity. The viscosity number is usually used to indicate the molecular weight of the polymer, and the polymer model is divided
PVC used to be the largest general-purpose plastic in the world, and it is widely used. It is widely used in construction materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc
SG3 (K-70, S1300): mostly used for soft products, hoses, wires and cables, films, shoe materials, toys, auto parts etc.
PVC RESIN SG3 has high purity, less fish eyes, easy to blister, high temperature resistance, insulation, soft product texture, etc. It is mainly used to produce soft products such as wires and cables, agricultural films, conveyor belts, and daily plastic products.
