With the development of China's construction industry, the development of related building materials industry has also a broader development space. With its own unique advantages, high quality prepainted color galvanized coil has been recognized by many users in the market.
The galvanized coil is cold rolled or hot rolled, and a thin layer of zinc is plated on the elongated steel coil. The production of low cost PPGI prepainted galvanized steel coil concentrates on the advantages of both galvanizing and strip steel, so that the product is not only corrosion-resistant, beautiful, but also has high dimensional accuracy, good surface quality, easier processing and material saving. The product can meet the requirements of the public to a certain extent, and can better meet the needs of users.
At present, the construction industry and the automotive industry in China have been continuously developing. The high quality prepainted color galvanized coil has become a shortage of products in China, and the related manufacturers of galvanized coils in China are producing galvanizing according to the current market demand. At the time of the board, efforts have been made to extend its service life and to some extent reduce the shortage of resources.
The low cost PPGI prepainted galvanized steel coil is fully in line with the needs of modern industry. It has been widely used in various industries such as building construction, wire and cable. The galvanized coil has stable performance, long service life and corrosion resistance, and is well received by consumers. The development prospect of high quality prepainted color galvanized coil is very broad, because in the development of industry, galvanized coil is inseparable.

Geomembrane type and manufacturing principle, pond liner textured hdpe geomembrane made in china is a relatively impervious geosynthetic material. According to different raw materials, it can be divided into two categories: polymer and asphalt. In order to meet different strength and deformation needs, there is no reinforcement. Reinforcement classification, according to the production process classification of geotextiles, can be divided into blow molding geomembrane, calendering geomembrane, extrusion geomembrane.
A. Blow molding geomembrane. The blow molding method is also called the tube film method. The blow molding method can be defined as the resin is melted and plasticized by the extruder, and then extruded through the annular die to form a thin-walled tube blank, which is inflated, cooled, and cut open. The geomembrane obtained by flattening is a blown geomembrane.
The principle of blow molding geomembrane manufacturing: the polymer and its auxiliary agent are put into the externally heated extruder through the hopper of the extruder, and then the screw, the compression, the metering action of the screw rotating through the extruder will be The material is melt-plasticized, and the tube blank in a molten state is extruded from an annular die. After the outlet end of the tube, the blank is melted, compressed air is blown from a vent hole in the center of the mold, and the tube is produced by a geomembrane manufacturer. Gradually expanding under the action of compressed air, at the same time, the outside of the tube blank is forcedly cooled. At this time, the end of the tube blank is forced to move at a uniform speed. At this time, a continuous cylindrical geomembrane can be obtained. The geomembrane is cut open and flattened to obtain a film (sheet) shape.
B. Calendering geomembrane. A calendering geomembrane can be defined as a method in which a thermoplastic plasticized plastic is passed through two or more counter-rotating rolls to form a predetermined size and used for a geomembrane (or sheet) of geotechnical materials, calendering geotechnical The high polymer material used in the membrane mainly refers to the classification of polyvinyl chloride and calendered geomembrane: the calendering geomembrane can be divided into a single layer of polyvinyl chloride geomembrane, a double layer of polyvinyl chloride composite geomembrane and a meshed polyvinyl chloride composite geomembrane.

Galvalumed steel sheet made in China is a new type of lightweight roof-bearing inorganic sheet which integrates lightweight, load-bearing, durable, heat preservation, heat insulation, waterproof, fireproof, sound insulation, explosion-proof and anti-seismic functions. The board inherits the reliability of traditional reinforced concrete roof slabs and absorbs the advantages of other lightweight panels while achieving lightweight and versatile while highlighting the safety and durability of the structure. Complete product specifications, quick installation and easy maintenance. Steel frame light roofing panels are mainly used for roofing of rail transit, industrial plants, warehouse logistics, large public buildings, stadiums, and other buildings. They can be matched with various structural forms such as concrete structures, light steel structures, and grids. Shandong HENGZE New Material Co., Ltd. is one of Galvalume Corrugated Roofing Sheet manufacturers.

Along the perimeter of the building on the low cost color-coated corrugated roofing sheet, prevent a ring of aerated concrete prosthetic plates. The length of the provocative version is twofold: 1500 mm and 1800 mm, and the length of the pick is one-third, 500 mm and 600 mm, by drilling, grouting, ribbing, and roofing of the rear of the provocative version. The corner plate can be reinforced concrete provocative version, but in the design, the blood medicine should pay attention to a few points:
1. When the front and rear wall sections are laid in a vertical direction with the roof panel, the prosthetic version should be anchored on the two roof panels.
2. The plaster should be nailed to the wire mesh.
3. If the drain is welded with a thin steel plate, special attention should be paid to the anti-corrosion treatment.
4. The drilling depth should be 25 mm smaller than the total thickness of the picking panel and the roof panel must not be penetrated. In the design of the roof panel, we must pay more attention to some details, so as to continuously promote the development of China's roofing panel industry, and let more consumers rest assured the quality of the manufacturer's roofing panel products, so it is fundamental for the roofing panel manufacturers. It is very important to make a good product.

Today, we continued to talk about the precautions of the high quality grinding disc.
1. In the grinding process, the coolant should be used correctly; if the coolant is not used, there must be a dustproof device.
2. Each piece of resin grinding disc is marked with high use and line speed. Before installing the machine, be sure to confirm the speed of the machine. Do not exceed the speed marked on the grinding disc to ensure that the machine has perfect protection device, the center hole of the cheap metal grinding disc and the center axis of the high quality grinding disc. Must match, otherwise, it cannot be used.
3. The flanges on both sides of the resin grinding disc must have the same shape and size. The flange diameter should meet the requirements, and there should be grooves on both sides.
4. When installing and fixing, be sure to be tight and appropriate. After the installation is completed, start the machine to idle for about one minute. No abnormality can be used. 5. Whether it is grinding or not, the pressure given should be uniform. It is strictly forbidden to collide with the workpiece when the high-quality grinding disc is adjusted and rotated. When entering the knife, it should be gradually progressive. When cutting large diameter workpieces, reduce the contact surface between the grinding disc and the workpiece.
