The development history of the overall shower room
generationIntegral shower room,FRP material manufacturing
FRP (Fiber Reinforced Plastics), the scientific name is "Fiber Reinforced Plastics", and the more intuitive name is "Fiber Reinforced Plastics". This is a composite material, a new type of material composed of fiber material and matrix material mixed in a certain ratio, and then extruded and drawn by a special die. Because FRP does not require a large press when it is made, it can make various shapes according to practical needs, which is very suitable for use in Japan with a small living area, and it is very common in the household shower rooms of Japanese users.
Strengths: This material has the characteristics of corrosion resistance, fatigue resistance, non-conductivity, less recycling, lighter than steel, and high strength. In the early use of the overall shower room, it does have an advantage. my country Eastern GroupIn 1974, my country's first FRP integrated shower room was produced. The manufacturing process is formed by wet resin, which requires simple equipment and low cost. FRP products are basically manufactured by hand lay-up process.
Disadvantages: manufactured by hand lay-upThe disadvantages of FRP shower room are low degree of mechanization, long production cycle and unstable quality. In addition, the anti-aging function of FRP is poor, the service life is about ten years, and the raw materials of the products are not delicate enough to meet the requirements of high-end customers.
Status: Following the advancement of my country's construction industrialization, hand-lay-up manufacturingFRP integrated shower room can no longer adapt to the various requirements of China's "low-carbon building" and quality control system; and people's personalized positioning of the integrated shower room is getting higher and higher, and FRP materials are gradually unable to adapt to the development of China's integrated shower room; With the continuous emergence of more new materials and new technologies, a generation of overall shower room products has gradually faded in the market.
The second-generation integral shower room,SMC material manufacturing
SMC (Sheet molding compound), the scientific name "sheet molding compound", is an unsaturated polyester resin material and also a kind of glass fiber reinforced plastic. The main raw materials are composed of GF (special yarn), UP (unsaturated resin), low shortening additives, MD (filler) and various additives. After heating and pressure, the molten sheet molding compound can evenly fill the cavity of the template. After a period of pressure-holding heating, solidify and shape. SMC products appeared in Europe in the early 1960s. Later, the United States and Japan successively improved this process.
Strengths:SMC material has excellent electrical functions, corrosion resistance, simple engineering planning, and its mechanical functions are good, and it can complete large-scale industrial production; especially construction work has always been exploring the implementation of factory installation, which allows SMC's sheet integrated molding characteristics to be obtained Performed well, enough to replace traditional technology. SMC products are manufactured under high temperature and high pressure, so the products have a high degree of anti-aging. Even if they are used in a high-temperature, humid bathroom environment, the product life can theoretically reach 20 years. As a whole shower room, the necessary waterproof and anti-leakage parameters can be guaranteed , Has obvious advantages.
Disadvantages: becauseSMC is an upgraded product of FRP. It is essentially a plastic composite material, which has inherent shortcomings: for example, the appearance is plastic, the touch is empty, and it is particularly not resistant to pollution from materials such as washing powder and toilet cleaner. The sense of quality is not high, and it is impossible to get used to the needs of customers with higher requirements such as star hotels and general household appliances. Also, because of mold constraints, the degree of personalization is low, the panel is not very decorative, and the bathroom cannot open windows or hang things with nails. At the same time, because the mold is fixed, it cannot be customized according to customer needs, resulting in a waste of utilization area.
