A clean room door, also known as a purification door, is a door used to maintain a stable clean room environment. Clean room refers to the indoor air cleanliness is higher than ordinary air room, often used in production, experiment, research and other fields, need to maintain a strict degree of cleanliness to ensure the quality of products and data. The clean door is the key equipment to ensure that the cleanliness of the clean room department is not affected by external pollution.
Types of clean doors
Clean doors are generally divided into two types: steel purification doors and color steel purification doors. Among them, the color steel purification door has higher cleanliness, corrosion resistance and durability, which is more suitable for the fluorine industry, semiconductor factories, medical institutions and other occasions that require higher cleanliness environment.
Process principle of color steel plate purification door
Color steel plate purification door has three main parts: door frame, door fan, seal. The door frame is made of aluminum alloy profile, the door fan is made of color steel plate material, the middle is filled with high-strength sound insulation material, and a single or double seal is used to ensure the stability and high cleanliness of the door body.
The process principle of color steel plate purification door is as follows:
1. Medical grade filter
The dust, sand, iron scrap and organic matter in front of the door are separated, and the particles below 0.5 microns are filtered out, so that the air on both sides of the door is clean.
2. Protective netting
The protective net is mainly used to isolate the influence between the external air flow and the internal air flow of the door hole.
3. Negative pressure
A negative pressure sensor is set up to prevent air pollution outside the door cavity caused by non-door automatic opening and ensure the internal cleanliness of the door cavity.
4.2~3 layers sealing strip
Through pressure balance technology, reduce air flow and pressure differences, using two sides of the top
The third level of the department ensures that the door is closed.
5. Meet the cleanliness standard bean
The surface treatment and installation of the color steel purification door shall meet the relevant standards to ensure that the internal air of the door can achieve the required cleanliness.
