​​​​​​1. Introduction

• PVC floor characters:
• ①Safety and protection: The PVC flooring injection moulding passivation process makes the product surface free of air holes, so that dirt cannot penetrate deep inside. The antibacterial performance provides a permanent sterilisation and antibacterial treatment, preventing microorganisms from multiplying inside and outside the floor. PVC flooring uses a multi-layer structure, using a reasonable coefficient of friction, as well as clever dispersion of walking pressure and shock absorption performance, ensuring safe walking. The design of the wear-resistant layer structure at the top of the PVC flooring highlights the advantages of the multi-layer structure, containing a glass fibre reinforcement layer, ensuring constant dimensional stability and ensuring that the floor is not deformed or damaged. At the same time, the elastic cushioning of the foam layer prevents bruising due to falls. The practicality of the flooring and its excellent price/performance ratio make it particularly suitable for areas such as sterile laboratories, electronic clean rooms and pharmaceutical production halls.
• ②Maintenance convenience: PVC flooring of different qualities in the practical application of the product will reflect the obvious differences. To wear performance, for example, excellent wear quality can reduce the waxing, cleaning and other daily maintenance frequency, reducing the cycle of maintenance costs. PVC flooring surface attached to the polyurethane finish with water resistance, chemical resistance and dimensional stability, with a strong wear-resistant transparent PVC cover, greatly simplifies the use of the cycle of tedious maintenance steps, ideal for the use of factory decoration of clean rooms and other areas of the requirements It is ideal for areas such as factory fit-out cleanrooms.
• Epoxy Self leveling Floor: The surface is seamlessly painted, dust-free, wear-resistant, impermeable, resistant to heavy pressure, easy to clean, and has a good compressive and impact strength, so the durability and service life of the flooring is relatively long. The thickness of the middle layer of construction can make a partial repair of the unevenness of the base surface, ensuring that the finished surface has a good levelness, improving usability and aesthetics.
• Epoxy colored sand floor:
• ①Epoxy colored sand floor is a seamlessly integrated new type of composite decorative floor composed of colored quartz sand and epoxy resin. It can be freely matched through one or more colored quartz sands of different colors to form a variety of decorative colors and patterns.
• ②It has the advantages of elegant decorative texture, abrasion resistance, compression resistance, chemical resistance, non-slip, fireproof, and waterproof. The color can be adjusted freely, the color is bright, the decorative effect is good, the colored sand can form a beautiful surface; high cleanliness, no continuous contact marks; excellent wear resistance, acid and alkali resistance, and can inhibit the production of mold and bacteria; adequate surface flatness and roughness.
• ③The thickness of epoxy colored sand floor coating is generally 3.0mm and 5.0mm, and the effective service life is more than 10 years. Surface form of the floor includes bright type, non-slip type, rolling surface and self-flowing surface;
• ④Epoxy colored sand floor is mainly used for occasions that require abrasion resistance, strong impact resistance, and high-end decoration. With a certain floor style, it is especially suitable for airports, large shopping malls, exhibition halls, subways, electronic communications, medical and health, high-end commercial places, food production workshops, grease meat plants, offices and school laboratories, and some places which pay attention to external cleaning and durable.
