NB sports wood floor engineer, for everyone to popularize some knowledge about gym wood floor log materials:
1. Standard of weight and volume ratio of log materials
With the shortage of the domestic sports wood floor log material market, in recent years, my country has imported more and more sports wood floor log materials from North America, South Asia, and other places. Different rates lead to large differences in wood weight, but the same or similar wood volume. Taking a 20-foot container full of African hedgehog red sandalwood rough sawn as an example, due to the difference in moisture content, its corresponding wood weight is mostly between 20 tons and 27 tons, and its corresponding wood volume is mostly between 16m3 and 17m3 (ie The average volume is between 16.5m3). In fact, when a container of the same size is filled with wood from the same region, the same tree species, similar specifications, and different moisture contents, although the corresponding weight varies greatly, the volume of the wood is relatively stable. This seemingly simple question that puzzles many people can find the answer only with the help of professional knowledge of wood science.
2. Standard for moisture content of raw wood materials
Freshly felled wood is raw wood. Imported wood loaded in ordinary containers is basically raw wood. Because trees need a lot of water in the process of growth, the moisture content of green wood is relatively high. Generally, the moisture content of raw wood and sapwood is 70% to 200%, and the moisture content of heartwood is 40% to 90%. For green wood, both the cell cavity and the cell wall contain water. When the raw material is naturally dried in the atmosphere, the free water in the cell cavity slowly evaporates. When there is no free water in the cell cavity, and the amount of bound water in the cell wall is saturated, the critical point is called the fiber saturation point. The corresponding moisture content at this time is called the fiber saturation point moisture content. The fiber saturation point of wood varies with tree species, temperature and measurement methods, and usually 30% is taken as the average fiber saturation point moisture content.
NB sports wood floors have built their own log bases in Northeast China and the Far East of Russia, so don't worry about this problem. However, sports wood flooring manufacturers without a raw material base, especially those who import raw wood materials for stadium wood floors from abroad, have to pay attention to the rationality of the standard moisture content, weight and volume of the stadium wood floor.
