Why do some wood flooring and other wood products have cracking, deformation and other quality problems after installation? Why is the beautiful wooden floor after installation used for a period of time after cracking deformation? This is the problem of moisture content of the wooden floor.
As we all know, whether it is solid wood flooring or laminate flooring, as long as it is made of natural materials, the wooden flooring will contain a certain amount of moisture. After the wood products are finished, the shape and material will not change. At this time, the key factors determining the intrinsic quality of the wood products are the wood moisture content and the dry stress. When the wood product reaches an equilibrium moisture content, the wood at this time is the least susceptible to cracking.
Wood moisture content: The percentage of the moisture content of the wood and the weight of the wood after drying.
The equilibrium moisture content of the wood: the moisture-stable stable moisture content or the desorption-stable moisture content of the wood under certain air conditions, called the equilibrium moisture content of the wood (solidified state of wood moisture).
So what is the water content that is qualified?
Is the wood more dry? The wood is placed in a certain environment, and after a long enough time, the water content will tend to an equilibrium value, called the equilibrium moisture content of the environment EMC. When the moisture content of the wood is higher than the equilibrium moisture content of the environment, the wood will shrink and contract, and vice versa. For example, the average annual equilibrium moisture content in Guangzhou is 15.1%, compared with 11.4% in Beijing. Drying to 11% of wood is suitable for Beijing, and it can be used in Guangzhou to absorb moisture and deform. Conversely, if the water content in Guangzhou is suitable for Beijing, there is a possibility of chapped. Different areas and different uses have different requirements for wood moisture content.
For flooring such as solid wood flooring and bamboo flooring, which is made of natural materials, it is ideal for adjusting the moisture content after 2 to 3 days in the site after unpacking. Do not directly dry the ground without drying it.
Aspheric lenses can increase the numerical aperture of a lens while minimizing system aberrations. Aspheric lenses may also reduce the number of elements needed in a multi-element system. Aspheric lenses can reduce overall system weight while providing advantages such as increasing throughput or simplifying assembly.
Convex Aspheric elements are used to reduce aberrations, aspheric lens is ideal for light collection, projection, illumination, detection, and condensing applications.
China Star Optics has strong and comprehensive technical capability, manufactured various aspherical products,including infrared material ZnSe,Ge,Si,ZnS etc.has already application in various high technology project and products.
