The fibers can be randomly arranged, flattened into a sheet called chopped strand mat, or woven into glass cloth. The plastic matrix can be a thermoset polymer matrix – mos

Nonwovens manufacturing starts by the arrangement of fibres in a sheet or web. The fibres can be staple fibres or filaments extruded from molten polymer granules.

As an equipment that must be used in many environments, air conditioning is very important for both production and life. In order to improve the air cleanliness of air intake and improve the efficiency of production and life, air conditioning filters are introduced into air conditioners, which are mainly divided into three kinds of air filters: primary effect, medium effect and high efficiency.

The role of the air filter.The compressed air from the air source contains excessive water vapor and oil droplets, as well as solid impurities, such as rust, sand, pipe sealant, etc. These will damage the piston seal ring and block the components.The small vent on the upper part shortens the service
