Relying on high efficiency and flexibility, high productivity, and in modern industry, laser cutting has the advantage of fast cutting speed. In particular, laser cutting of non-metallic materials plays an important role in traditional manufacturing, and many non-metallic plastic products and laser cutting play an irreplaceable role in the processing of multi-layer composite materials.
We all know that the principle of laser cutting is to use the corresponding power density laser beam to irradiate the cutting material, so that the cutting point of the material is immediately heated to the evaporation temperature, and then evaporated to form a processing gap to achieve the purpose of processing. During this process, extremely complex physical and chemical changes have taken place in the deep or surface material of the workpiece. Simply put, physical changes are the evaporation of dust and particles; chemical changes can produce odors, stickiness, and depending on the specific process material itself, the specific process material itself.
Non-metal laser cutting produces dust
Analysis of the causes of dust generated by non-metal laser cutting.
- The dust generated by laser cutting of non-metallic materials is a physical change. In the process of processing, professional laser dust removal devices can be used for dust removal, such as standard needle felt composite membrane filter bags and membrane filters, which can basically filter and purify more than 90% of the dust;
- The peculiar smell and stickiness produced by laser cutting non-metallic materials are easy to block the filter due to oily substances and viscous substances. The oily substances belong to the dust category that is difficult to handle. Activated carbon adsorption purification is a traditional method for the treatment of molten odors to achieve the purification effect;
- Non-metallic laser cutting dust has a physical and chemical mixture, that is, the dust contains odor and viscosity particles. The purification equipment needs to have the ability to purify dust and odor. It is necessary to estimate and judge the nature of the dust in advance, and configure the correct purification device.
Design and functional requirements of laser cutting non-metallic dust treatment purifier.
- For the laser cutting dust treatment of non-metallic materials, the dust purification equipment first has a high-efficiency filtering function, strong oil resistance and anti-stickiness;
- For the treatment of odor dust, laser dust removal equipment must have effective treatment of activated carbon dust;
- Considering that the dust after laser cutting may also be caused by complex changes in different materials, density, temperature, space characteristics and other factors, it is required to reserve a process design for additional accessories when installing dust removal equipment.
