With its advantages of high efficiency, flexibility, high production capacity, and fast cutting speed, laser cutting has been widely used in modern industry. In particular, laser cutting of non-metallic materials has occupied an important position as the mainstay in traditional manufacturing. Laser cutting has played an irreplaceable role in the processing of many non-metallic plastic products, multi-layer composite synthetic materials, etc.

As we all know, the principle of laser cutting is to use a high-power density laser beam to irradiate the material to be cut, so that the cutting point of the material is instantly heated to the vaporization temperature, and then evaporates to form a processing gap to achieve the purpose of processing. In this process, the deep or surface materials of the workpiece being processed undergo extremely complex physical and chemical changes. Specifically, physical changes will produce dust and particles in the form of vaporized free particles; chemical changes will produce odor, stickiness, oiliness and other substances, which will vary according to the specific material being processed:

Analysis of dust from laser cutting of non-metallic materials

1. The dust generated by laser cutting of non-metallic materials is a physical change. Professional laser dust removal devices can be used to remove dust during the processing process, such as standard needle felt coated filter bags and coated filters, which can basically achieve more than 90% dust filtration and purification;

2. Odors generated by laser cutting of non-metallic materials, Sticky and oily dusts are difficult to handle because oily and sticky substances are very easy to clog filters. The conventional treatment method for odors caused by high-temperature burning and melting is activated carbon adsorption purification to achieve the purification effect;

3. If the dust from laser cutting of non-metallic materials has both physical and chemical properties, that is, the dust is a particle containing odor and stickiness, the purification equipment is required to have both dust purification and odor purification capabilities. This operation requires the estimation and judgment of dust properties in advance to prepare for the configuration of the correct purification device.

Design and functional requirements of dust treatment purifier for laser cutting of non-metallic materials:

1. For dust treatment of laser cutting of non-metallic materials, the smoke purification equipment must first have a high-efficiency filtration function and strong oil resistance and anti-stickiness;

2. For odorous dust treatment, the laser dust removal equipment must have an activated carbon adsorption function to ensure that the odorous dust is effectively treated;

3. Considering that the dust after laser cutting may also show complex changes due to different materials, density, temperature, spatial characteristics and other factors, it is required to reserve a process backup design for additional accessories when installing the dust removal equipment.
