The Laboratory Ground Code requires the Clean Workshop Design Code Gb50457(20088.3.3.2) : The ground shall be integral, flat, crack-free, wear-resistant, impact-resistant and moisture-proof And should not be easy to collect static electricity and easy to clean dust. The code for Fire Protection Design of building interior decoration (GB50222 -- 954.0.4) stipulates that the fire performance grade of ground decoration materials for Class A and B factories shall be Class A non-burning, c Workshop Floor Decoration Materials of the burning performance class B 1 should be difficult to burn. In order to meet the requirements of the above specifications, there are self-leveling ground, anti-static polyvinyl chloride ground, non-fire terrazzo anti-static ground and so on. Self-leveling floor 1. Concept Epoxy self-leveling coating is made by adding various additives, pigments, fillers and other epoxy as film forming materials It is a solvent-free, self-leveling, particle-dense, thick-paste epoxy floor coating. 2, performance characteristics 1 use solvent-free epoxy with high-quality curing agent and conductive powder made. 2 smooth surface, beautiful, up to the mirror effect, with a very good decorative, can meet the 100 grade cleanliness requirements grade. ACID, Alkali, salt and oil corrosion resistance, especially strong Alkali Resistance. Wear resistance, pressure resistance, impact resistance, a certain degree of flexibility. Moistureproof and antibacterial. 6 integrity is good, a film in more than 1mm, easy construction. 7 has a combustion property of Class B 1 Flame retardancy. 3, the scope of application of self-leveling floor is used for the electronic and micro-electronic industries requiring high cleanliness, beauty, dust-free, asepsis and anti-static, pharmaceutical industry, blood products industry and so on. In the design of pharmaceutical workshop, the self-leveling floor is often used in the clean room floor of the new or old type C pharmaceutical workshop. Anti-static Polyvinyl Chloride 1, concept PVC anti-static floor is based on polyvinyl chloride resin, adding conductive materials, stabilizers, plasticizers and pigments and other auxiliary materials, the electrostatic conductive network formed by the interface of plastic particles is made by a special processing technology. 2. Performance characteristics the conductor material is evenly distributed throughout the whole floor tile, making it permanent conductive; High Mechanical Strength, strong bearing capacity; smooth and non-porous surface with good chemical resistance; good indoor decoration effect Easy construction, easy cleaning, maintenance, good wear-resistant, waterproof, anti-chemical reaction performance, uniform specifications and color maintenance, anti-aging, less dust production, combustion performance for Class B1 flame retardant. 3, scope of application anti-static polyvinyl chloride ground is suitable for Electronics, micro-electronics, computer room, electric power dispatching room, precision instruments, purification plant and other places requiring anti-static The utility model is commonly used for the ground reconstruction of the clean room of the Class C workshop with cement or Terrazzo as the base of the old workshop. Non-ignition terrazzo floor concept non-ignition anti-static terrazzo floor to meet the maximum permanent non-ignition, anti-static, high load bearing, high cleanliness, wear-resistant, anti-aging, corrosion-resistant, fire-resistant, beautiful and simple maintenance, low cost or no cost, and many other strict requirements, achieve the building characteristics of the ground and anti-static characteristics of the perfect integration. In performance, the non-fire anti-static Terrazzo can widely replace the current market of PVC anti-static ground, rubber anti-static ground, Epoxy self-flow flat anti-static ground, anti-static ceramic tile and so on. 2. Performance Characteristics 1 meet the requirements of national construction industry GB502092002 and JC507 -- 1993. 2 Does Not Crack, high mechanical strength, load-bearing compression, not afraid of heavy rolling, not afraid of heavy drag, no shrinkage, no deformation. Non-ignition, aging resistance, stain resistance, corrosion resistance, no odor, no environmental pollution. No dust, high cleanliness, cleanliness to meet the pharmaceutical, chip manufacturing and other high clean environment requirements. 5 is similar to the traditional construction technology of ready-made Terrazzo, and can be directly carried out as a civil engineering project. The combustion performance is Class A non-combustibility. 3. SCOPE of application non-fire terrazzo floor is suitable for new plant, machine room and the existing ground needs a larger area of the environment or cleanliness requirements of extremely high environment and other anti-static requirements, the condition is the completion of the civil ground cushion, can leave at least 3 cm leveling layer and surface layer thickness. Do not fire terrazzo floor is often used in medicine new or Old Class A explosion-proof workshop clean room floor.
