After the start of 2014, news about the quality of furniture is often reported in the media. Especially in the golden period of buying furniture and building materials in May, these furniture quality related news is the sensitive nerve that touches the consumers, so that consumers "talk about quality change." At this time, some high-tech new materials widely used in furniture production, because of the misunderstanding of the market, are caught in the whirlpool of this question. Among them, PU foam furniture bears the brunt. Before the evaluation is good or bad, we may wish to have a 360° view on the PU foam furniture. What is PU foam furniture PU is the abbreviation of polyurethane, which was used in chemical production in the 1950s. The manufacturing process is a foaming technology in which raw materials are chemically reacted to form a foamed plastic, which is then cured. The pu foam board that we often hear is a kind of plate made by pu foaming. The shape of the plate is very beautiful, and the tensile strength is 2.5 times that of the ordinary aluminum plate, which is very convenient for construction operation. At present, PU foam boards on the market mainly include polyurethane PU foam board, aluminum magnesium manganese Pu foam board, PU foam board EPS sandwich board, low density PU foam board and the like. Due to the excellent performance of PU foam board, such as compression resistance, moisture resistance, good texture and easy processing, it is widely used in the furniture market at home and abroad, especially in Europe and the United States, and has achieved good economic and social benefits. The difference from ordinary furniture first look at the appearance of the material. We have seen a large number of PU foam furniture in the home store, distribution center, without exception, the characteristics are beautiful. The whole appearance is integrally formed, without extra screw holes and connecting ports, and the lacquer effect and detailed carving are outstanding. The main disadvantage of PU foam furniture is that it cannot be fireproof. This is also a constraint to the development of new synthetic materials. Followed by the price. In terms of raw materials and manufacturing costs, PU foam furniture has great advantages compared with pure solid wood furniture and cork homes, and it is naturally more affordable to reflect the terminal price. Foamed furniture may not sound as loud as solid wood furniture, but its high cost performance has won the favor of many post-80s and post-90s buyers. Furthermore, it is environmentally friendly, which is the most controversial point of PU foam furniture. PU foam furniture itself is non-toxic and harmless. Some consumers think it is toxic, but it will happen under burning conditions. In general, the combustion of chemical synthetic materials produces toxic gases, such as our common plastics. PU foam furniture is very environmentally friendly under normal use. Development status and prospects PU foam is the latest international plate. In recent years, many breakthroughs have been made in PU foaming technology. Honeywell, a world-renowned company, presented the latest foaming technology at the 2011 American Chemical Society's Polyurethane Technology Conference, further strengthening the thermal insulation of PU foam and reducing the impact on global warming. According to incomplete statistics, more than 3,000 related personnel have participated in the training of polyurethane safety courses. It is obvious that the development of this field is important and its development prospects cannot be underestimated. In China, according to the latest data, there are nine industries in the top ten industrial revitalization plans issued by the state, which are related to polyurethane, which shows that they are widely used. In the development and utilization of new energy, polyurethane is widely used in high-speed rail, subway, urban rail transit sleepers, sleeper pads, etc., is an indispensable new material in the new situation. In summary, we must have a more comprehensive understanding of PU foam and PU foam furniture. As a successful example of the integration of emerging industries and ancient crafts, the PU foaming process has already penetrated into all areas of our lives. At present, PU foam materials are rapidly developing at a rate of 30-50% per year, and its application in the furniture industry will become more and more mature, and will be received by more consumers.
