PVC flooring is very popular in today's world of a new lightweight floor decorative materials, also known as "lightweight flooring materials". Is a popular product in Europe and the United States and Asia, Japan and South Korea, popular abroad, from the early 80's began to enter the Chinese market, so far in the domestic large and medium-sized cities has been generally recognized, the use of a very wide range of places, such as families, hospitals, schools, office buildings, factories, public **** place, supermarkets, businesses, stadiums and other places. "PVC flooring" refers to the use of polyvinyl chloride material production floor. Specifically, it is polyvinyl chloride and its **** polyresin as the main raw material, adding fillers, plasticizers, stabilizers, coloring agents and other auxiliary materials, on a sheet-like continuous substrate, by the coating process or by the calendering, extrusion or extrusion process to produce and become. \x0d\ I. Classification: \x0d\ (1) from the structure of the main multi-layer composite and homogeneous translucent type and semi-homogeneous body type 3 kinds. The so-called multi-layer composite PVC flooring is that it is a multi-layer structure, generally by 4 ~ 5 layers of structural stacking and become, generally wear-resistant layer (including UV treatment), printing film layer, glass fiber layer, elastic foam layer, grass-roots level. The so-called homogeneous translucent type PVC flooring is that it is up and down homogeneous translucent, that is, from the surface to the bottom, from top to bottom, are the same kind of flower color. \x0d\(2) from the form is divided into roll flooring and sheet flooring 2 kinds; the so-called roll flooring is a softer texture of a roll of flooring, generally its width of 1.5 meters, 2 meters, etc., the length of each roll of 20 meters, the total thickness of 1.6mm-3.2mm (commercial flooring, sports flooring can be thicker up to 4mm, 5mm, 6mm, etc.). Sheet flooring specifications are more, mainly divided into strip material and square material. \x0d\ strip specifications are: 4 "× 36" (101.6mm × 914.4mm) 6 "× 36" (152.4mm × 914.4mm) 8 "× 36" (203.2mm × 914.4mm), the thickness of 1.2mm-3.0mm. \x0d\ square specifications are: 12 "× 12" (304.8mm × 304.8mm) 18 "× 36" (203.2mm × 914.4mm), the thickness of 1.2mm -3.0mm. ×304.8mm) 18"×18" (457.2mm × 457.2mm) 24"×24" (609.6mm × 609.6mm)\x0d\ Thickness: 1.2mm-3.0mm. \x0d\ (3) from the degree of wear-resistant is divided into general-purpose and durable 2 kinds. Domestic production and use are mainly general-purpose PVC flooring, some very high traffic places such as airports, railway stations, etc. need to lay durable PVC flooring, its wear-resistant degree is stronger, longer service life, while the price is also more expensive. \x0d\(4) from the use of the place up, the main points are: \x0d\ education system (including schools, training centers, kindergartens, etc.) \x0d\ medical system (including hospitals, laboratories, pharmaceutical factories, sanatoriums, etc.) \x0d\ commercial system (including shopping malls, supermarkets, hotels, entertainment and recreation centers, food and beverage, specialty stores, etc.) \x0d\ sports system (stadiums, activity centers, etc.) \x0d\\office systems (office buildings, conference rooms, etc.) \x0d\\industrial systems (factory plants, warehouses, etc.) \x0d\transportation systems (airports, railway stations, bus stations, terminals, etc.) \x0d\\home systems (family indoor living room, bedrooms, kitchens, balconies, studies, etc.) \x0d\\2, knowledge extension \x0d\on PVC flooring advantages: \x0d\1, green Environmental protection: the main raw material for the production of PVC flooring is polyvinyl chloride, PVC is an environmentally friendly and non-toxic renewable resources, it has long been used in large quantities in people's daily lives, such as tableware, medical infusion bags, etc., and its environmental protection is no need to worry. Among them, the main component of stone plastic flooring (sheet) is natural stone powder, which does not contain any radioactive elements detected by the national authority, and it is a new type of green floor decoration material. Any qualified PVC flooring needs to go through the IS09000 international quality system certification as well as ISO14001 international green certification. \x0d\2, ultra-light and ultra-thin: PVC flooring is only 1.6mm-9mm thick, the weight per square meter is only 2-7KG, in the construction of the building for the building load-bearing and space-saving, has an incomparable advantage, in the transformation of the old building has a special advantage. \x0d\3, super wear-resistant: PVC flooring surface has a special layer of high-tech processing of transparent wear-resistant layer, the surface of the special treatment of super wear-resistant layer fully guarantees the excellent wear-resistant performance of the floor materials, PVC flooring surface of the wear-resistant layer according to the thickness of the different under normal circumstances can be used for 5-10 years, the wear-resistant layer of the thickness and quality of the direct decision of the PVC Floor use time, standard test results show that 0.55mm thick wear-resistant layer of the ground can be used under normal circumstances for more than 5 years, 0.7mm thick wear-resistant layer of the ground is enough to use for more than 10 years, so it is even more super wear-resistant. Because of the super wear-resistant, so in the high-traffic hospitals, schools, office buildings, shopping malls, supermarkets, transportation and other places, PVC flooring is becoming more and more popular. \x0d\4, high elasticity and strong resistance: PVC flooring texture is soft so elasticity is very good, in the impact of heavy objects have a good elastic recovery, rolled flooring texture is soft and elasticity is better, and its foot comfort is called "flooring soft gold", at the same time, PVC flooring has a very strong impact resistance, for the impact of heavy damage has a very strong elastic recovery, will not cause damage. The elasticity of the recovery, will not cause damage. Excellent PVC flooring can minimize the ground to the human body injury, and can be dispersed on the impact of the foot, the latest research data show that in the flow of large space paved with excellent PVC flooring, the ratio of falls and injuries compared to other floors reduced by nearly 70%. \x0d\5, super anti-slip: PVC flooring surface wear layer has a special anti-slip, and compared with ordinary flooring materials, PVC flooring in the case of viscous water foot feeling more astringent, less easy to slip, that is, the more the more water the more astringent. Also therefore, so in the public *** safety requirements of the higher public *** places such as airports, hospitals, kindergartens, schools, etc. is the preferred floor decoration materials, in recent years in China has been very popular. \x0d\6, fire-retardant: the quality of qualified PVC floor fire indicators up to B1 level, B1 level, that is to say, fire performance is very good, second only to stone. pvc flooring itself will not burn and can prevent combustion; will not produce breathable poisonous and harmful gases (according to the security department to provide the figures: 95% of people injured in the fire is due to the combustion of the toxic fumes and gases produced). (According to the figures provided by the security department: 95% of the people injured in fires are due to toxic smoke and gases produced during combustion). \x0d\7, waterproof and moisture-proof: PVC flooring due to the main component is vinyl resin, and water has no affinity, so its natural not afraid of water, as long as it is not a long time to be immersed in will not be damaged; and will not be moldy because of high humidity. \x0d\8, sound-absorbing anti-noise: PVC flooring has an ordinary flooring materials can not be compared to the sound-absorbing effect, its sound absorption of up to 20 decibels, so in need of quiet environments such as hospital wards, school libraries, lecture halls, theaters, etc. choose PVC flooring, you no longer need to be for the sound of high-heeled shoes and the ground impact on your thinking and worry about the PVC flooring to provide you with a more comfortable and more humane! PVC flooring can provide you with a more comfortable, more humanized living environment. \x0d\9, antimicrobial properties: PVC flooring surface after a special antibacterial treatment, PVC flooring surface is also a special increase in the antimicrobial agent, the vast majority of bacteria have a strong ability to kill and inhibit bacterial reproduction. \x0d\10, small seams and seamless welding: special color PVC sheet flooring by strict construction and installation, the seams are very small, almost invisible from a distance; PVC rolled flooring with seamless welding technology can achieve completely seamless, which is not possible with ordinary flooring, and therefore can be the overall effect of the ground and the visual effect of the maximum optimization; in the overall effect of the floor of the requirements of higher In the environment of the overall effect of the ground requires a high level of office, as well as high requirements for sterilization environment, such as hospital operating rooms, PVC flooring is the most ideal choice. \x0d\11, cutting splicing simple and easy: with a better art knife is good can be arbitrarily cut, at the same time can be used in a combination of materials of different colors, give full play to the ingenuity of the designer, to achieve the most desirable decorative effect; enough to make your ground into a work of art, so that your living space has become a temple of art, full of artistic atmosphere. \x0d\12, fast installation and construction: PVC flooring installation and construction is very fast, without cement mortar, ground conditions with special environmentally friendly adhesive bonding, 24 hours after the use. \x0d\13, color variety: PVC flooring color variety, such as carpet pattern, stone pattern, wood flooring pattern, and so on, and even personalized customization can be achieved.
