Chlorinated polyethylene is a saturated polymer material with a white powder appearance. It is non-toxic and tasteless. It has excellent weather resistance, ozone resistance, chemical resistance and aging resistance. It has good oil resistance, flame retardancy and coloring properties. It is an excellent impact modifier for PVC plastics and a synthetic rubber with good comprehensive performance. It has a very wide range of applications and has been widely used in cables, wires, hoses, tapes, rubber and plastic products, sealing materials, flame retardant transport belt , Waterproof coiled material, film and various profiles and other products.
As a PVC impact modifier, CPE135A has many advantages such as low price, excellent performance, and excellent aging resistance, but it has certain disadvantages in the use of high impact and high hardness products and low temperature resistant products CPE135A. For example, in the formulation of rigid PVC, a large amount of CPE will reduce the hardness and rigidity, which reduces the physical properties of the product; in addition, when the low temperature resistance requirement of PVC products exceeds minus 30°C, CPE135A cannot meet the requirements. Under normal circumstances, modified CPE, such as ACM, RGC135A, etc., can be selected for rigidity and hardness improvement; for low-temperature resistance modification, impact-resistant ACR or other impact modifiers with lower glass transition temperature can be selected.

When the plasma CNC cutting machine cuts the workpiece, the cutting current regulation problem of the machine plasma power supply is very important. It is the most important cutting process parameter, and directly determines the thickness and speed of the cutting, ie, the cutting ability. Regarding the impact, the direct manifestation of the following is the selection form of the cutting current of the plasma cutting machine:
1. The cutting current of the plasma cutting machine increases, the plasma arc energy increases, the cutting ability increases, and the cutting speed increases.
2. The cutting current of plasma cutting machine increases, the diameter of plasma arc increases, and the thickening of the arc makes the incision widen;
3. When the cutting current of the plasma cutting machine is too large, the thermal load of the nozzle increases, the nozzle is damaged prematurely, and the cutting quality naturally decreases, and even normal cutting cannot be performed. Therefore, the cutting current and the corresponding nozzle should be selected correctly according to the thickness of the material before cutting.
In the correct use of CNC plasma cutting machine for high-quality rapid cutting, the cutting process parameters must be deeply understood and mastered. Only in such a situation can the plasma cutting equipment achieve its maximum efficiency, and its cut workpieces will also reach The best results, the following Haiyu CNC to explain the cutting plasma current cutting current regulation parameters of the plasma cutting machine when cutting the workpiece, for the majority of users reference learning.
