After entering the plum rainy season, the continuous rain continued to make many owners who renovate the floor have a headache and insomnia. Due to the wet and rainy weather, there are a lot of drawbacks in the decoration of wooden floors, and these drawbacks cannot be corrected in a timely manner. In fact, the selection of moisture-proof materials on the ground is the key, as long as the problem should be handled properly, hold every detail, even wet summer, it can save a lot of unnecessary trouble, make a satisfactory love nest. Meiyu quarter floor moisture selection is key to ground moisture resistant materials First, according to the floor selection floor If the humidity of a low floor is large, you have to choose a floor with good stability. A high-rise apartment is relatively low in moisture content, easy to ventilate, and relatively dry. You can choose a floor with low shrinkage of wood. Different manufacturers have different processes when processing floors, which results in different floor properties. Be sure to ask when purchasing. If you are not sure, you can choose to use bermuda, ants, teak floors. These floors can be used on various floors. Second, value "moisture-proof performance" Moisture resistance is the most important technical indicator of wood flooring. Wood flooring with poor moisture resistance, under long-term "steaming" of the ground, once the moisture enters, the edge of the wood floor must be warped, resulting in damage to the wooden floor. The high-quality wood floor uses a high-density substrate, which has excellent moisture resistance, and the water-absorption thickness expansion ratio is far less than the national standard. In addition, the special wear-resistant layer, decorative paper, and balancing layer can “close†the substrate well, ensuring that the overall moisture resistance of the wooden floor is better. Third, choose the material and size The solid wood flooring is mainly selected from some fine-grained woods such as eucalyptus, borneol, rosewood, scented tea, ash, teak, birch, etc. It is bizarre that fake and shoddy mixed, what kind of gold grapefruit, gold does not change, rich and valuable wood, so that customers are really difficult to distinguish between good and bad not know. So when it comes to buying, it mainly depends on its rating. Solid wood flooring is divided into three grades: AA grade, A grade, and B grade, and AA grade has the highest quality. Fourth, select the moisture content The moisture content of wood floor is very important. The moisture content of the purchased floor must be consistent with the local equilibrium water content. Be sure to determine the moisture content of the floor, if you do not have a moisture meter, do not buy the floor. The method of measuring the equilibrium moisture content is very simple. In the exhibition hall, the moisture content of the purchased varieties is first determined, and then the moisture content of the wooden floor of the purchased varieties is checked out. If the moisture content of the two varieties is only 1%-2%, it is a qualified product. Fifth, the processing accuracy Instruct consumers to use several pieces of flooring to assemble them on the ground to see whether the accuracy of their processing quality is smooth and smooth, whether the grooves and fittings, installation gaps, or anti-deformation grooves are tightly assembled. Good floor workmanship is precise, accurate dimensions, smooth corners, no height difference. Six, substrate quality and process The flatness and gloss of the floor surface is one of the main criteria for floor leveling. When you buy a floor, you should carefully check whether the floor surface is smooth. If there is any problem such as cracking, rot, clip, dead knot, bug eyes, etc., it is best not to purchase it. Seven, paint quality Whether it is light or matt lacquer flooring, attention should be paid to whether the paint film on the floor surface is uniform, plump, smooth, and free of defects such as blisters, holes, and edge collapse when selecting. Eight, check whether it meets the environmental protection requirements Because many low-quality and low-priced brands cannot process floor products with safe and environmentally friendly materials, resulting in a large amount of residues of formaldehyde and toxic and harmful substances, it may pose potential health hazards to infants and pregnant women. Therefore, when consumers purchase, Must pay attention to check whether the product meets the environmental protection requirements. Nine, the key is to lay Pavement flooring pays attention to “good weather and good weather.†Heavenly weather refers to fine weather. It is best to be sunny and not rainy for about 7 days of installation; geography requires that you do not install the floor before the ground is dry; people must be Find a professional worker to install the floor for you. At the same time, a professional moisture-proof floor mat is laid under the floor to prevent the floor from getting damp. A special reminder is that within 48 hours of floorboarding, walking and placing heavy objects should be avoided to allow sufficient time for the adhesive bonding of the floor. Freshly-laid floors are best cleaned with a vacuum cleaner or broom. The above about the rainy season in the rainy season floor, choose the key to moisture-proof materials on the ground is a simple introduction to here, and I hope to help you.

Manufacturing Process
Yuhong Group supplies the highest quality welded finned tubes to any part of the world. The newly designed manufacturing facility, with our state-of-the-art high frequency resistance welding machines, enable us to perform large scale projects in reduced times.
The steel fin, that may be solid or serrated, is helically wound and continuously welded to the tube by high frequency electric resistance welding. This produces an homogeneous, clean and continuous fin-totube bond with no additional weld material, for a very efficient heat flow and resistance to corrosion.
There are some applications for which one or the other fin type is preferred. While in some cases fouling and cleaning considerations will favour solid fins, serrated fins are superior with respect to weight, compactness and price.
The use of high-frequency current results in very localised heating of the tube surface and the edge of the fin. This skin effect produces higher weld speeds, hence post-weld heat treatment is not considered necessary because of the superficial nature of the changes in the microstructure.
Tube bending:
Our finning machines are equipped with online single or duplex cold bending equipment that can manipulate both ends of tubes in a single operation, thus ensuring exact alignment of the ends. Our bending machines are capable of bending both bare or finned tubes with diameters from 31 mm to 76 mm.
Corrosion protection:
If required, the external surfaces of finned tubes can be treated with a protective coating. Our engineers are always ready to assist you with design considerations to meet your specific product needs.
