Nowadays, there are many types of flooring available in the building materials market, ranging from traditional solid wood floors to sturdy wood floors (impregnated paper laminated wood floors) that have emerged since the 1990s, and in recent years have been derived from the solid wood flooring family. The solid wood composite floor, in the purchase of the floor should pay attention to the following points: >>>Industry revealed that counterfeit wood floor fake screen 1, the purchase of solid wood flooring (1) Kinds of wood flooring Consumers must not be confused by the name, to find out the real material so as not to be fooled. (2) Specifications Solid wood flooring is not as wide as possible, it is recommended to choose the short length of the floor; length, width of the wood floor is relatively easy to deform. (3) Water content of the floor The moisture content of wood floor is very important. The moisture content of the purchased floor should be consistent with the local equilibrium moisture content. (4) Processing accuracy General wooden floor can be removed after unpacking 10 or so on the flat on the freehand assembly, observe the anastomosis, assembling the gap, the height difference between adjacent plates, if the strict joint, feel no significant height difference. (5) Substrate quality Whether the floor is dead, insect eyes, cracking, decay, bacteria and other defects. Objectively, there are chromatic aberration and pattern unevenness, which cannot be avoided. It would be unreasonable to over-pursue the floor without chromatic aberration. (6) paint quality When you buy to see whether the film is uniform, full, smooth, should pay attention to no bubbles, paint leaks and holes, but also pay attention to wear resistance. 2, purchase of solid wood flooring At present, the solid wood composite flooring sold on the market can be divided into two categories: three-layer solid wood composite flooring and multi-layer solid wood composite flooring. Their advantages and disadvantages can be distinguished according to the following aspects: Processing accuracy: The greatest advantage of solid wood composite flooring, is the processing accuracy High, therefore, when choosing solid wood composite flooring, it is necessary to carefully observe whether the splicing of the floor is tight, and there should be no obvious height difference between two adjacent plates. Surface paint film: high-grade solid wood composite floor, should use advanced UV matt paint, this paint is UV-cured, its wear resistance is very good, general household use without waxing maintenance, do not need more than ten years Lacquer. Another key indicator is the degree of mattness. The degree of brightness of the floor should first be considered soft and elegant, without visually irritating the eyes. 3, strengthen the purchase of wooden floor (1) Surface wear resistance This indicator is selected based on the use of the occasion, family use is greater than 6,000 rpm, public places use more than 9000 rpm. (2) formaldehyde emission The adhesive used in laminate flooring contains a certain amount of formaldehyde. China has issued mandatory standards for air formaldehyde concentration in public places. The regulations do not exceed 1.5 mg/L. (3) Water absorption thickness expansion rate The higher the index, the more apt the expansion of the floor, the state stipulates that this indicator qualified products should be within 10.0%. (4) Internal bond strength The greater the intensity, the more tightly the combination of laminate flooring, the national provisions of this indicator should reach 1.0Mpa above.

As a filler metal welding wire or both as a conductive wire welding materials used. When gas welding and gas tungsten arc welding, welding filler metals used; in submerged arc welding, electroslag welding and other time MIG arc welding, welding filler metals both, but also conductive electrodes. Surface oxidation coated wire is not the role of flux.
