Best Clean Room Flooring Solutions - Cleanroom Flooring Requirements & Materials

When constructing a clean room, in order to achieve the required cleanliness level, not only the construction of the wall is required to meet some conditions, but also the selection of the floor material. So what kind of flooring should be chosen for the clean room? Here are the best floor materials for clean rooms.

Clean Room Flooring Requirements

Clean room is also called clean workshop. It refers to a space in which bacteria, viruses, and dust pollution are strictly controlled, and the degree of air cleanliness reaches a certain level for human activities and normal operation. Room pressure, air velocity and air distribution, noise, vibration, lighting, and static control are within a certain range of requirements. To fulfill these requirements, the floor of the clean room as an important building material is also demanded to meet the following requirements:

• Hard material, good integrity, smooth and flat

• No cracking, abrasion resistance, impact resistance

• Anti-static

• Non-slip

• Moisture and corrosion resistant

• Easy to clean and maintain

Clean Room Flooring Materials

However, different industries choose different materials for the floor of the clean room. Here we introduce the most commonly used floor materials and floor plans of the clean room and the applicable areas:

Clean Room Raised Floor System

Raised floor is a system that consists of completely removable and replaceable floor panels that rest on adjustable bases, the bases being connected to one another by supporting beams in order to make the area under the floor usable for building services. Cleanroom Rasied Access Floor will be a certain amount of air space. It can be used for down wiring and return air to prevent mold and residual moisture, and easy to install, maintain and change the installation. The surface of the raised floor can use static dissipative panels to achieve anti-static effect. It is often used in vertical unidirectional flow purification workshop (large area).

Self Leveling Epoxy Flooring

The coating of Self Leveling Epoxy Flooring is a solvent-free high-performance coating formulated with epoxy resin as the coating film-forming material, and then adding curing agent, non-volatile reactive diluent, auxiliary agent, pigment and filler. The film-forming process of epoxy self-leveling coating is a chemical film-forming method. After a soluble low-molecular-weight epoxy resin is coated on the surface of a substrate, intermolecular reactions occur and the molecular weight is further increased or cross-linked. Tough paint film. Epoxy self-leveling not only has the advantages of terrazzo floor, but also has the advantages of more corrosion resistance, wear resistance, and easier cleaning. It can meet the requirements of higher cleanliness, so it is mostly used in 10000 and 100 clean rooms. At present, it is adopted and accepted by many pharmaceutical companies at home and abroad, and is generally used in water injection workshop, lyophilized powder injection workshop and biological products workshop.

Terrazzo Floor

Terrazzo floor is a kind of non-elastic floor, which has the characteristics of good integrity, good mechanical strength, abrasion resistance, heavy pressure resistance, antistatic, easy to clean (washable) and so on. However, because microbes and dust particles may still be hidden in the terrazzo surface gap, a waxing treatment is required during grinding. Terrazzo is generally used in workshops with lower cleanliness (level 100,000 clean zone), such as: solid preparation workshops, API workshops, etc.

Anti-static PVC Flooring (ESD Vinyl Flooring)

ESD Vinyl Floor coverings made of polyvinyl chloride (PVC) are sheeted in thicknesses of 1.5 to 2 mm. These adhesives are adhered to the substrate with a dispersing adhesive, and antistatic conductive copper foil is laid on the bottom to conduct static electricity. The joints are thermally welded using PVC electrode welding. Smooth, slightly elastic, not easy to dust, easy to scrub and clean, wear-resistant and corrosion-resistant. However, it is easy to age due to ultraviolet radiation, so it is not suitable for places where ultraviolet lamps are often used. Generally used in changing rooms, packaging rooms, laboratories and other rooms. Due to the different expansion and contraction properties of the plastic board and the concrete base, it is not suitable for large-area workshops, otherwise, it will cause shelling.

Acid-proof Ceramic Floor Tiles

Use Acid-proof Ceramic Floor Tiles can resist corrosion, but the quality is more brittle, can not withstand impact, after crushing, the corrosion resistance will be reduced. This kind of floor can be used in the section with corrosive media in the raw material workshop. Due to the complicated construction and high cost, it is suitable for local use with corrosive media dripping. For example, the equipment with corrosive media is arranged centrally, and then this part of the ground is enclosed by a water line, and the inside of the water line is covered with such a floor.
