Purify the door - as the name implies requires a very high sealing performance and heat preservation performance, supporting care and clean room engineering with the door, cleaning door is characterized in general requirements to achieve the clean room standard, such as corrosion, easy dust, easy to clean, no dead.
There are two common physical cleaning methods for general steel cleaning doors. The door is clean clean room decontamination in terms: refers to the supporting insurance and clean room engineering with the door, door for purification plant in cleanroom door easy cleaning and disinfection, no dead ends to design and manufacture, the frame is made of 1.5mm thickness of galvanized steel or stainless steel doors, with 1.2 1.5mm thick stainless steel seamless welded. In the middle of polyurethane foam, the frame around the seal, can guarantee the sealing of different grade clean range gate. The clean room and the purification door are like two kinds of purification doors:
One is the adsorption filtration: activated carbon is a porous material containing carbon, it has a highly developed pore structure, porous structure of activated carbon to provide a large surface area, and gas (impurities) full contact, thus giving the adsorption properties of activated carbon are unique, so it is very easy to achieve the purpose of absorbing impurities collected. Just like magnetic force, all molecules have mutual attraction. The disadvantage is that ordinary activated carbon can not adsorb toxic gas, so it is inefficient and easy to remove.
Two mechanical filter: HEPA (HEPA filter), reached the standard of HEPA, the effective rate of 0.3 to 99.998% microns, the characters of the HEPA network is the air can pass, but small particles cannot pass. The HEPA filter consists of a stack of continuously folded front and second folded fiberglass membranes to form wave shaped gaskets for holding and supporting filtration media.
