In the market of floor decoration materials, floor leather has become a popular choice for renovation of rented houses, renovation of old houses and temporary space decoration with its advantages of high cost performance, convenient laying and diverse styles. Many people only pay attention to the appearance, thickness and price when purchasing floor leather, but ignore a key problem-the production process directly determines the durability, fit and service life of floor leather. Among them, hot melt adhesive coating process, as the core link of floor leather lamination, is the key to affect its quality. Today, we will come to the popular science hot melt adhesive coating process to reveal the production logic behind high-quality floor leather, and at the same time understand how professional gluing equipment can protect the quality of floor leather. The birth of high-quality floor leather can not be separated from the support of high-quality raw materials, but also from standardized and accurate production technology. Floor leather is mostly multi-layer structure, mainly composed of surface wear-resistant layer, middle printing layer and bottom buffer layer, and the close adhesion of these layers depends entirely on the hot melt adhesive coating process. Simply put, hot melt adhesive coating is to apply hot melt adhesive evenly on the surface of floor leather layers through professional equipment, and realize the firm bonding of all layers after cooling. The accuracy of this step directly determines whether there will be problems such as delamination, degumming and bulging in the later use of floor leather.

Hot melt adhesive coating equipment in the industry needs accurate temperature control, quantity control ability and stable coating performance. At present, most of the mature hot melt adhesive coating equipment in the industry has the functions of precise tension control and PID intelligent temperature control, which can accurately control the coating amount, coating speed and glue temperature of hot melt adhesive, and effectively avoid common problems such as uneven coating, glue overflow and missing coating. At the same time, the equipment should be flexible, and the coating parameters can be flexibly adjusted according to floor leathers with different thicknesses and materials, so as to meet the production requirements of household floor leathers, commercial floor leathers and other specifications. In terms of glue solution treatment, high-quality coating equipment will carry out special treatment on the glue box, such as Teflon coating on the inner surface of the glue box to prevent the glue solution from carbonization, ensure that the glue is always in the best state, reduce nozzle blockage, and ensure production efficiency and coating effect. In addition, environmental protection is also an important development direction of coating equipment at present. High-quality equipment mostly uses 100% solid hot melt adhesive, which does not need drying equipment, has lower energy consumption, and is solvent-free and pollution-free, which not only meets the requirements of environmental protection production, but also avoids health hazards generated during operation. Rui 'an Jiayuan Machinery Co., Ltd., which has been deeply involved in the field of gluing equipment for many years, and the hot melt adhesive coating equipment produced by Jiayuan meet the core needs of floor leather production. Jiayuan focuses on R&D, production and sales of coating equipment. With mature technology and rich industry experience, the coating equipment produced has outstanding performance in accuracy, stability and adaptability, which can provide stable and efficient process support for floor leather production, help production enterprises solve various pain points in the coating process and improve the quality of floor leather from the source. In addition to the support of equipment and the standard of hot melt adhesive coating process, it is also necessary to cooperate with the standardized operation process. Operators should accurately set coating parameters and control the temperature and coating speed of glue solution according to the specific specifications of floor leather; At the same time, it is necessary to do a good job in the daily maintenance and cleaning of the equipment, and regularly check the nozzle, plastic box and other parts to avoid affecting the coating effect due to equipment failure. Only with the double guarantee of equipment and operation can the hot melt adhesive coating process play its greatest role and produce high-quality floor leather with high fit and strong durability.
