In the face of the complicated floor brands and types in the market, do you know how to choose correctly and effectively? Before the home decoration design, you must be aware of the number in order to make your home decoration no problem. In the process of purchasing the floor, you not only need to understand the type of floor, but also remember the core performance indicators of the floor to distinguish the quality of the floor. How many quality indicators does the home decoration choose for the floor? 1, formaldehyde emission The amount of formaldehyde released is an important indicator for measuring home improvement materials. The standard of green building materials stipulated by international environmental protection organizations is not higher than 8mg/100g, and the allowable release standard of formaldehyde for environmentally-marked artificial boards is 0.20mg/m3. The floor is mainly divided into solid wood flooring, solid wood composite flooring, impregnated paper laminated wooden flooring (commonly known as laminate flooring), and bamboo flooring. According to the national standard, the formaldehyde emission requirement of solid wood flooring is required. The formaldehyde emission requirement of solid wood composite floor and bamboo floor is 1.5mg/L, and the laminate flooring is divided into E0 grade, E1 grade, E0 grade 0.5 mg/L, E1 grade 1.5 mg. /L. 2, surface wear resistance The surface wear resistance of the floor refers to the detection index of the wear resistance of the first layer wear-resistant layer of aluminum oxide, which is measured by the number of revolutions of the detecting device. The higher the number of revolutions, the better the quality of the wooden floor and the more wearable. The national standard stipulates that the wear resistance of household grade 1 laminate flooring is ≥6000 rpm, the brand laminate flooring is usually maintained at around 8500 rpm, and the non-brand laminate flooring cannot meet the national standard. This is an important indicator of the quality of laminate flooring. Some people think that the higher the wear resistance of the floor, the longer the floor should be used, but the wear resistance value is not the only standard to measure the service life of the composite floor. The latest national standard stipulates that the initial wear resistance of household laminate flooring is 4500 rpm. 3, surface scratch resistance index The surface scratch resistance index of the wooden floor reflects its ability to resist sharp scratches. The latest national standard of 2010 is ≥4.0N surface decorative pattern is not scratched, brand-reinforced flooring can generally reach the national standard, and the laminate flooring that does not reach the national standard can only reach 2-3N. Of course, the performance indicators of wood flooring also include moisture content, water absorption thickness expansion rate, static bending strength, surface corrosion resistance, surface bonding strength, internal bonding strength, impact resistance and the like. However, as long as you memorize these three physical and chemical performance indicators purchased from the above floor, you can easily identify the floor. The "Super SAX/SCX" series of ion exchange resins are specially designed for the fine purification of drugs and natural products. The materials are separated according to the difference in surface charge of the molecules. It has high resolution, long life, stable performance under organic solvent, strong acid and alkali conditions, excellent resistance to high salt samples, and no tailing phenomenon for separation of basic compounds. It has broad application prospects in the fields of biopharmaceuticals, modernization of traditional Chinese medicine, natural health products, high-end beverages.
