After the implementation of domestic natural protection projects, after the logging bans and restrictions on forest areas, the wood raw materials produced by furniture have decreased, and the high-quality and precious wood resources suitable for making furniture have become less and less, although relying on exports can relatively ease the current wood supply. The dilemma, but from the perspective of market supply, as the world's forest resources decrease, high-quality large-diameter logs are increasingly scarce, and natural wood production has fallen sharply. The shortage of domestic wood supply will become more prominent in the next few years. Timber prices are facing a continuous increase of about 10%, and the entire solid wood furniture market is facing pressure from raw material prices. Although wood furniture is also very important in the market, solid wood furniture is hard to catch on. Instead, solid wood furniture has started to sell well. Coupled with people's consumption level, consumer psychology and habits have become more or less a factor restricting the development of solid wood furniture. China is a country lacking wood in Shaolin, and the rapid economic development has made the demand for wooden boards more and more. As a substitute for natural solid wood, various artificial boards are more and more valued by people. In addition, the country also encourages consumers to use board wood furniture, because it can save a lot of precious hardwood materials, which is conducive to protecting forest resources and the environment. In recent years, with the improvement of the material and cultural level and the change of people's aesthetics, the pursuit of reversing simplicity and returning to nature has become the new fashion of modern Chinese. The pattern of furniture has been renovated and the material structure has also undergone significant changes. Panel furniture made of man-made board as the base material is very popular in the furniture market.
Several types of reactive filler such as Silica Fume or microsilica, metakaolin, work very well in mortar or concrete applications. Owes to secondary reaction with hydrated lime, reactive fillers can improve the long-term strength development and early strength at water immersion condition for various mortars which strength development are hindered by additives such as Redispersible Polymer Powder or Cellulose Ether. Some lightweight fillers like exfoliated vermiculite are also key ingredients for lightweight mortar, thermal insulation mortar or fireproof mortar based on cement or gypsum.
