选购PVC地板必需要提早知道的几点

　　PVC floor is very popular in the world today on a new light body decoration materials, also known as "light body material". Is a kind of Europe and the United States and Asia, Japan and South Korea's popular products, popular abroad, from the beginning in the early 80 s to enter China's market, in the domestic large and medium-sized cities has been recognized throughout, use is very extensive, for family, hospital, school, work building, factory, public places, supermarkets, commercial, sports venues and other places. "PVC floor" it is to point to the floor board that chooses polyvinyl chloride data to produce. Detail is to polyvinyl chloride and its copolymerization resin as the primary material, adding fillers, plasticizers, stabilizers, coloring agents and other auxiliary materials, in the sheet continuous substrate, by coating process or by calendering, extrusion or kneading process produced.

　　But people can have the following three kinds of fault to PVC floor board commonly to know:

　　The first mistake: "take out a knife or key and other sharp tools, in the appearance of the PVC floor to scratch, there are scratches that do not think wear resistance."

　　In fact, the country of PVC floor wear resistance test is not a brief use of sharp tool in the appearance of the row, is to use a flat flat shape to play a millstone, in the state of pressure 1Kg grinding test floor, in the rotation of grinding how many turn, the floor surface wear-resisting layer is worn exposed by the bottom of the revolution. The rotation of this node is a goal of measuring the abrasion resistance of PVC floor. For instance compound floor turns number country lowest standard 1500 turns. So PVC floor wear resistance is determined by the national testing organization. Super wear-resisting, PVC floor surface has a layer of special other through high-tech processing of tongming wear-resisting layer, its wear-resisting revolution can reach 30000. The wear-resisting revolution of relatively wear-resisting aggrandizement wood floor in traditional data on the ground is only 13000 turn, good aggrandizement floor also has 20000 turn only. Appearance of special processing super wear-resisting layer and ensure the excellent wear-resisting function of the ground material, PVC floor exterior wear-resisting layer according to the thickness of the different under normal conditions can use 5 to 10 years, wear-resisting layer thickness and quality of the resolution for the use of PVC floor time directly, specification test results show the wear-resisting layer of 0.55 mm thick on the ground can use more than 5 years in the normal condition, the wear-resisting layer of 0.7 mm thick on the ground to apply for more than 10 years, so it is super wear resistance. As a result of having super wear resistance, so in the hospital, campus, work building, shopping mall, supermarket, transportation and other places with large flow of people, PVC floor is more and more popular.

　　Second mistake: "fire retardant is not burning".

　　Some users want to take a lighter to the point of PVC floor, see can burn up, burning up is not fire prevention, burning up is flame retardant. In fact, the country to PVC floor fire level requirements to reach the B1 level of the specification, according to the national specification of non-combustible information for fire level A, such as stone, brick. The skill of class B1 flame retardant specification contains a cotton ball with a diameter of 10mm, dipped in alcohol, and placed on the PVC floor for natural burning. After the cotton ball is burned out, measure the diameter of the burned PVC floor mark. If the diameter is less than 50mm, it is the class B1 flame retardant specification. Instead of watching and burning. The quality qualified PVC floor fire goal can reach B1 class, B1 class also is to say fire prevention function is very outstanding, next to stone. PVC floor itself will not burn and can obstruct the burning; The smoke that the PVC floor of high quality produces when be forced to light on fire also won't produce injury to human body for certain, won't produce the poisonous and harmful gas of the sex that cause a breath.

　　The third mistake: "smell with your nose is not environmentally friendly".

　　It is more accurate to say that there should be a strong stimulus smell of PVC floor is not environmentally friendly. PVC material itself is not formaldehyde, PVC floor in the production process is not allowed to use formaldehyde, qualified PVC floor should be 100% formaldehyde free, there may be aromatic agent and agent smell, will not give people's body damage, will not let people feel uncomfortable. The PVC sports floor that has a part of the company on market place now chooses the method that glue sticks to produce, because the glue contains formaldehyde, so such floor is to have pungent smell, can affect the body health of people. So it is also important to select high quality and qualified glue.
