Introduction of bidirectional plastic grille Bidirectional plastic grille is made of high polymer by extrusion to form a plate, punched, and then stretched longitudinally and horizontally. Bidirectional stretch plastic geogrid is suitable for various dykes and roadbed reinforcement, slope protection, cave wall reinforcement, and foundation reinforcement carried by large airports, parking lots, wharf yards, etc. Because bidirectional plastic grille has many advantages: such as increasing the bearing capacity of the road (ground) foundation and extending the service life of the road (ground) foundation. It can effectively prevent the road (ground) surface from collapsing or cracking, and keep the ground beautiful and tidy. Moreover, the construction is convenient, time-saving, labor-saving, shortening the construction period, and reducing maintenance costs. In addition, it can also replace metal mesh for underground false top nets in coal mines. Therefore, bidirectional plastic grating has been widely used in actual construction, and the foundation reinforcement construction effect suitable for large-scale bearing is remarkable. The main application scope of bidirectional plastic grille is: subgrade reinforcement of various highways, railways, airports; foundation reinforcement carried by large parking lots and wharves; slope protection of railways and highways, culverts enhancement; secondary enhancement of soil slope enhanced by unidirectional stretching geogrid, further enhancing soil slope, preventing soil erosion; mine, tunnel reinforcement. The construction process of bidirectional plastic grille requires that the paving surface of the geogrid should be relatively flat. After the paving layer experience is qualified, in order to prevent vertical skew, first draw a white line or hanging line on the paving layer according to the width, you can start paving, and then fix the end of the grille with iron nails (8 nails per meter wide, fixed at a uniform distance). After fixing the end of the grille, use a paver to slowly pull the grille forward. Manual tightening and straightening is carried out once every 10 meters long until one roll of grille is laid, and another roll is laid, and the operation is the same as before. After laying one roll, use a 6T-10T roller to roll it in the forward direction from the starting point. (If paved on the middle surface layer and leveling layer, it is advisable to use a steel roller roller; if the grille is laid directly on a concrete pavement, a rubber roller roller is appropriate.) Paving: The length of the section to be laid in units of roll length. After the length of the section to be paved is paved, the paving quality is checked as a whole, and then the next section is paved. When the next section is paved, the grille and the grille can be lapped with a lap length of 10-15CM, and the second section is paved in the forward direction after fixing it with iron nails or wooden wedges. By analogy, the operation requirements are the same. Why is the price of plastic geogrid of the same specification so different from different manufacturers? Are these so-called “same specification” plastic geogrid of different quotes really the same? If there is a difference, where is the difference? Today, Zhengze Engineering Materials Co., Ltd. will explain in detail for you: Where is the price difference of plastic geogrid? When it comes to prices, the first thing we think about is the difference in raw materials. Indeed, Zhengze plastic geogrid raw materials are divided into polypropylene particles and polyethylene particles. The raw materials of the two are different, and the plastic geogrid produced is also different; in the process of production, the plastic particles have fluidity, plasticity, and can be processed under certain conditions. Using this characteristic, we heat the polypropylene raw material through the machine to make the raw material flow state, so that it can be processed by the machine; when normal conditions are restored (such as removing pressure and cooling), it still maintains the shape of the processing Polymers are called plastics. We analyze from the raw materials used to make plastic geogrid; the first is to plan the cost of the product through the analysis of raw materials; the other is to study the performance of the product through the analysis of raw materials, what kind of raw materials produce better performance, what kind of raw materials produce products with poor performance, all of which must be understood in the production process; as a purchaser, you should also know more, this is why The price-performance ratio between products is different. When we do the experiment in reverse, we can clearly see its components; that is, the plastic geogrid is heated, and when heated to a certain extent, the geogrid is immediately melted by the fire into a liquid, and this returns to the state in which the plastic particles were heated at that time. This is one of the reasons why the gap between plastic geogrid in the market is so large; the cost of geogrid produced using recycled materials is relatively much lower than the cost of new materials, so it is not difficult to find that the geogrid gap in the market is very large. The plastic geogrid produced by Shandong Liantuo Engineering Materials Co., Ltd. is 100% guaranteed to be made of new materials. We can mail samples for our customers free of charge. You can judge the appearance, color, hardness, etc. of plastic geogrid by comparing the appearance, color, hardness, etc. Secondly, the production process is different, as far as plastic geogrid is concerned, the key to the production process is the stretching process, with Zhengze plastic geogrid as the main research object, Shandong Liantuo Engineering Materials Co., Ltd. through DSC analysis of the sample rib structure, found that the geogrid price will fluctuate according to the different tensile process parameters, through further research, can control the geogrid price, ribs in more depth The crystallinity of the parts is different, and the crystallinity of the specimen after stretching is higher than that of the unstretched specimen; the crystallinity of the specimen at a lower tensile temperature is similar to that of the specimen at a higher tensile rate. 02
