The weaving method of vinyl coated mesh

Cheap and high quality vinyl coated mesh supply

Vinyl coated mesh is a widely used fencing material that is favored for its great corrosion resistance, good weather resistance and beautiful appearance. It is usually made of wire (such as steel wire) that is braided and then coated with a vinyl material (pvc or polyvinyl chloride). This paper will introduce the weaving method of vinyl coated mesh and its production process in detail.
Raw material preparation
The production of vinyl coated mesh requires the preparation of wire as the base material. These wires are usually made of high-quality mild steel with high strength and toughness. Before weaving, the wire needs to be rigorously cleaned and pre-treated to remove surface oxides, oil and other impurities, ensuring that the subsequent coating can be firmly attached.
Weaving technology
Weaving is a key step in forming vinyl coated mesh. There are two common weaving methods: Welded mesh and woven mesh.
Welded mesh: Welded mesh is fixed together by resistance welding of crossed wires at each intersection. This method enables the formation of a very robust grid structure, which is suitable for applications where high stability is required.
Woven mesh: Woven mesh is the use of a special knitting machine, through the staggered weaving method to fix the wire together. Woven nets are more flexible and suitable for applications that require bending or shape changes.
Regardless of the braiding method, the tension and spacing of the wires need to be precisely controlled to ensure the uniformity and strength of the final product. In addition, it is also necessary to pay attention to the direction of the wire during the weaving process to achieve good structural stability and aesthetic effect.
Coating technology
After the weaving is complete, the next step is to coat the vinyl coated mesh. The purpose of the coating is to enhance the corrosion resistance of the wire and extend the service life.
Dipping: Dipping is to soak the woven metal mesh in the molten state of pvc liquid, through the way of infiltration so that pvc evenly attached to the surface of the wire. During the dipping process, the temperature and time need to be strictly controlled to ensure uniform coating thickness.
Spraying: Spraying is another commonly used coating method, using a spray gun to spray heated pvc particles onto a wire mesh. The advantage of spraying is that a more uniform and smooth surface can be obtained.
Whether dipping or spraying, the coating needs to be cured after completion, and the pvc material is fully cured through high temperature baking to form a strong protective layer.
Quality inspection
After the coating is completed, the vinyl coated mesh is subjected to a series of quality checks to ensure that the product meets the relevant standards. Inspection items usually include but are not limited to dimensional accuracy, coating thickness, surface finish, tensile strength, etc.
Application field
Vinyl coated mesh is widely used in many fields because of its great performance and beautiful appearance. In agriculture, for example, it can be used to build fences to protect crops from animals; in industrial places, it can be used as a protective net to ensure the safety of the work area; in residential areas, vinyl coated mesh is often used as a beautiful and practical wall material.
In short, vinyl coated mesh is not only a practical building material, but also a product of modern industrial civilization. Through the in-depth understanding of weaving methods, we can better understand and use this important material to contribute to the progress and development of society.
