Solid wood flooring attracts consumers with its unique luxurious, comfortable and natural advantages. However, in the current solid wood flooring market, there are many brands, prices are different, quality is uneven, how to buy the right product? The following content is helpful to you: 1. What is solid wood flooring? Solid wood flooring is a floor that is directly machined from wood. 2, What are the characteristics of solid wood flooring? Solid wood flooring is one of the most commonly used materials for interior floor decoration. The product is naturally simple, natural and noble, and can create an elegant and elegant living environment with human beings; good elasticity, comfortable feet; cool in winter and cool in summer, can regulate indoor temperature and humidity; itself does not emit harmful gases, is Real green environmental protection home improvement materials. 3, what types of solid wood flooring? Solid wood flooring can be divided into concrete floor slabs, flat grounding panels, and inlaid flooring. The most common one is the concrete grounding panels. According to whether the surface is painted, it can be divided into painted flooring and unpainted flooring (commonly known as plain board). Now the most common is the UV paint lacquer flooring; according to the species can be divided into domestic wood floor and imported wood floor. The wood species commonly used in domestic production include birch, ash, eucalyptus, maple, and commonly used wood species such as croton, merbau, yamu, balsam, ant wood, teak, zelkova, and two. Wing bean, four-seed wood, iron wire and so on. 4. How is a solid wood floor graded? China's solid wood flooring standards provide solid wood flooring is divided into superior products, first-class products and qualified products in three levels. In this regard, consumers are reminded that other forms of classification do not meet China's solid wood flooring standards. For example, some manufacturers have a “AAA†mark rating, which is an enterprise behavior. 5, how to determine what kind of wood flooring to buy? The price difference of solid wood flooring of different wood species may be very large, and the difference in wood species often determines the shade and texture pattern of the floor color. Consumers should decide what kind of floor to buy based on their economic capabilities and their love of color and texture, and the strength of the interior light. Choosing the color of the floor should consider the harmony with the overall tone of the room. The general principle is: Avoid the top-heavy tone. The selection of hardwood flooring can be simply divided into: light, medium and dark materials. The light-colored material has a uniform color and a lively style, which can fully express the warmth of the family. The medium color adaptability is strong, and the dark material calms the atmosphere, among which there are rare and rare balsamic pigeonpeas, teakwood, and Lvshan mulberry; the stability is better with ant wood, eucalyptus hematoxylin, merbau, teak, etc.; Ant wood, fragrant two-winged beans, etc.; 6, how to choose the size of the floor? The size of the floor relates to the ability of the floor to resist deformation. When the other conditions are the same, the smaller floor is more difficult to deform. Therefore, the floor size should not be too short and should be narrow and not wide. In addition, the floor size also relates to the price and the size of the room, and the large-sized floor has a higher price. Smaller rooms are also not suitable for laying large-sized floors. Some solid wood flooring manufacturers have continuously introduced long and wide solid wood floors for convenience in production and cater to consumers' fashion trends. This type of floor surface looks luxurious and luxurious. I wonder if it is a natural product because it is too long and wide. Quality control is more difficult, especially the problem of changes in the water content in the four seasons. Wet and dry shrinkage will occur after a period of time. Deformation. 7, how to choose the appearance quality? Solid wood floor board quality according to GB/T 15036-2001 standard is divided into excellent products, first-class products, qualified products three levels. The surface of the board is rotted and lacks edges. There are three grades that are not allowed; floor surface cracks: superior products, first-class products are not allowed, and qualified products are allowed to have two; floor surface joints: superior products, first-class products are allowed to have 2 ~4, but there are size restrictions. The number of qualified products is not limited. Dead knots and boring holes: Premium products are not allowed, and there is a limit to the number of first-class products. Chromatic aberration: The standard does not require this. Grade is one of the important factors that affect prices. Choose high-quality solid wood flooring should have a natural tone, clear and varied wood grain. If the color of the floor surface is heavy, it may be intentional to conceal the surface defects of the floor, and the small color difference is not necessarily good. At the same time, due to the different locations of the floor blocks in their mothers, the trees, there are differences in sapwood, heartwood, wood, wood, shade, and sun, and the cutting methods of the plates are chord-cut and radial-cut, respectively. Therefore, chromatic aberration must exist. It is the color difference, the natural texture, and the rich texture structure that highlight the natural style of solid wood flooring. International home decoration now has a wide variety of styles, including large variations in color, varying lengths and types of wood. As our country's consumer environmental awareness increases, it will inevitably tend to this style of decoration. If the surface has cracks and other defects, it can be used according to the laying needs during construction, and its defects can be removed. 8, how to choose the processing accuracy? Consumers can use simple methods to select floor processing accuracy. Take 10 pieces of floorboards from the packing box to simulate and assemble them on the flat ground. Touch the hand and see the precision and smoothness of the processing quality. Whether it is flat, smooth, tongue and groove, installation gap and other assembly is tightly sewn. A good floor should be precision workmanship, accurate dimensions, flat corners, no height difference. Anti-deformation groove (back groove) is very important, its shape, quantity, depth directly affect the safety of the floor. 9, how to choose paint quality? Now common is the UV paint floor, there are light paint and matt paint and other types. It should be observed whether the paint film is even, full, smooth, no paint leakage, no bubbles, no holes. It is best to seal on six sides. 10. Pick a floor with acceptable moisture content. The moisture content is a crucial factor that affects the deformation of solid wood flooring after pavement. When the floor is purchased, it can be rapidly detected by the moisture meter of the distributor, and if the distributor does not have a moisture content meter, the quality cannot be discussed.
Although there are many types of tapping screws, they all have the following similarities: Round head Tapping screw,hex tapping screw,flat head tapping screw,pan head tapping screw,truss head tapping screw Shenzhen Lanejoy Technology Co.,LTD , http://www.grill-grid.com
(1) are generally made of carbonized carbon steel (accounting for 99% of total production). It can also be made of stainless steel or non-ferrous metals.
(2) The product must be heat treated. Carbon steel tapping screws must be carbonized and stainless steel tapping screws must be solution hardened. In order to make tapping screws to meet the requirements of the standard of mechanical properties and performance.
(3) The product surface hardness is high, the core toughness is good. That is, "soft inside strong outside". This is a major feature of tapping Screw performance requirements. If the surface hardness is low, it can not be screwed into the matrix; If the core toughness is poor, a twist will break, can not be used. So "inside soft outside steel" is self-tapping screw to meet the use of performance, very important requirements.
(4) The surface of the product needs surface protection treatment, generally electroplating treatment. Some product surface must be treated by phosphate (photostatting), such as wall panel self - tapping screws for photostatting.
(5) Production by cold heading process. It is recommended to use high-speed cold heading machine and high-speed wire rolling machine or high-speed planetary wire rolling machine. High speed is emphasized here to ensure product quality. Only the head of tapping screw produced by high-speed machine is well formed and the thread quality is high.
