What are the main chemical components that produce odor when laser cutting acrylic (PMMA) and how to deal with them

Recently, a customer inquired about our company's solution to the problem of odor generated by laser cutting of acrylic (PMMA) material. Let's see how Guangdong Kolaijie Technology Co., Ltd. has solved this problem.

The customer is equipped with a high-power exhaust fan, and the pipeline discharges to the roof. At the same time, front-end water filtration is also used, but the odor problem still exists, and the laser cutting site is limited, with a limited budget.

Firstly, we need to know what acrylic is? Acrylic is actually polymethyl methacrylate material, commonly known as acrylic plastic. What kind of exhaust gas does acrylic laser cutting produce? Firstly, there are dust particles, followed by exhaust gas, which includes inhalable powders and volatile compounds such as formaldehyde, methyl acrylate, benzene, and ethyl acrylate copolymers. This is the source of the pungent odor.

How to deal with the odor of acrylic (PMMA) during laser cutting?

Usually, the concentration of odorous waste gas from acrylic cutting is less than 100mg/m3, which belongs to organic waste gas with room temperature, low air volume, and low concentration; Based on the client's budget and site conditions, Guangdong Kolaijie suggests using activated carbon adsorption technology for treatment. The process of activated carbon adsorption technology is to first use high-density dust removal bags to greatly adsorb and filter dust and smoke particles. After collection, odors and individual small particles enter the activated carbon filter chamber, which is equipped with medium to high efficiency and modified activated carbon filter cartridges for multi-stage filtration, effectively adsorbing the smoke generated during cutting and releasing purified air.

Returning to the beginning, the customer ultimately chose the KJ-L800c laser soot purifier after our technical engineer's scheme design and equipment selection. This purifier has the characteristics of low cost, high efficiency, moderate size, quiet operation, and high purification efficiency.

Above is our company's information on odor treatment during laser cutting of acrylic. We hope it can be helpful to you.
