What is the concept and understanding of the clean room?
"Clean-free workshop" refers to cleaning the particles of harmful air, harmful air, bacteria, etc. in the air within a certain space, and the indoor temperature, cleanliness, indoor pressure, airflow velocity and airflow distribution, noise vibration and illumination, Static electricity is controlled within a certain range and given a room for common depiction. That is, no matter how the external air conditions are changed, the interior can have the functions of cleanliness, temperature, humidity and pressure that have been set as required. Characteristics.
The most important role of the clean room is to control the cleanliness and temperature of the atmosphere that the products (such as silicon chips) are exposed to, so that the products can be produced and manufactured in an excellent environment. This space is called dust-free. workshop.
Clean room cleanliness: the degree of cleanliness of a certain particle size in the air per unit volume.
Class 1000 dust-free workshop, the primary filtration is greater than or equal to 0.5 UM dust particles, the air supply volume is generally more than 50 times according to the number of ventilation.
What is the composition of the dust-free workshop: depicting the construction of clean room workshops in general according to national standards, dust-free workshop construction methods can be divided into two types: civil engineering planning and assembly type, and assembly type is widely used.
The equipment and application of the Class-A clean room have the following characteristics:
1> All the repairing components of the assembled dust-free workshop are finished in the factory according to the common modulus and series processing, which is suitable for mass production, stable quality and active supply.
2> The dust-free workshop is maneuverable, that is, it is suitable for the new plant supporting equipment, and it is also suitable for the purification technology modification of the old dust-free workshop. Patching plans can also be combined with the needs of the process to open the case.
3> The clean room needs to be assisted with a small construction area and low requirements for earth building renovation.

Biomass material is a renewable resource, but different biomass forms are different. Therefore, it is necessary to make biomass pellets of uniform shape and size from biomass raw materials, so that biomass material can be better utilized. Biomass Pellet Burner is based on biomass pellets as fuel, which is different from general Biomass Burner. The biomass burner produced by our company adopts semi-gasification combustion mode, without tar, waste water and other waste discharges. The Widely Used Biomass Pellet Burner can be directly connected with biomass boilers, Biomass Heating and various industrial kilns.
