The International Research Group headed by Kikuchi Rumi, an environmental resource research center at the Japan Institute of Physical and Chemical Research, has developed the "Comprehensive Soil Evaluation Method Using Semi-Carbonized Biomass" to improve the soil by comprehensively analyzing the physical, chemical and biological characteristics of the soil. Soil is composed of gravel of varying sizes, humus remaining after microbial decomposition, and minerals such as rainwater and rivers. These materials are intertwined to form a cohesive structure that holds the soil in moderation of moisture and provides oxygen to plants and soil organisms through the air passages. So far, many academic circles have published research reports on the soil environmental cycle, but the perspectives are mostly single. Because plants absorb nutrients, moisture and breathe through the roots, soil characteristics have a significant impact on plant growth. To maintain the normal growth of plants, the soil must have adequate humidity and air. In Sub-Saharan Africa, for example, the soil is very dry and the soil becomes extremely hardened after being hydrated, making agricultural cultivation difficult. In a report published in the British journal Science Report, the team claimed that in order to improve the soil structure, they used NMR methods to construct structures. They first broken the leaves of tung oil tree, heated to 240 degrees Celsius in anaerobic environment at low temperature, made of semi-carbonized biomass. The analysis was then conducted by infrared spectroscopy, thermal analysis, particle size distribution and two-dimensional solution nuclear magnetic resonance, and the moisture and hemicellulose components in the biomass formed by thermal decomposition were confirmed from the results of the metabolomic analysis. Based on the above analysis, the research team mixed semi-carbonized tung oil tree with various proportions in poor soil. It was found that the improved soil formed aggregate structure, and the structural stability of the physical characteristics appeared, which proved that the soil water-holding capacity increased . In addition, the phenomenon of symbiosis between plants and microorganisms also appeared after soil improvement. Researchers said the assessment could be used to rehabilitate the expanding desert strip and make it arable land, bringing new hope for food-ridden Africa's growing population.
The main function of the edge banding is to seal the cross-section of the board, so as to avoid the damage of the board and the adverse factors (mainly moisture) in the process of use and prevent the formaldehyde inside the board from volatilizing, and at the same time achieve the effect of beautiful decoration.
The product has the following main features: smooth surface, no blistering, no ribbing, moderate gloss, smooth surface and back surface, uniform thickness, uniform width, reasonable hardness, high elasticity, good quality, strong wear resistance, trimmed and sealed The color of the side and the side is close to the surface color, not whitish, good gloss, and the overall color of the finished furniture is coordinated.

First, the edge banding has the function of blocking harmful gases such as formaldehyde
Good edge banding or multi-sided edge banding can reduce the amount of formaldehyde emission per unit time (ie, slow down the emission rate). It is worth noting that edge banding will not reduce the formaldehyde content of the board, but this has the advantage of edge banding. It can reduce the formaldehyde emission per unit time of unenvironmentally-friendly sheets to a level that is acceptable to humans and does not affect health.
Second, the role of beautifying furniture
Good edge banding has the effect of beautifying office furniture, but if it is to be beautiful, the requirements for edge banding will be higher. Not only must the edge banding and the end surface of the board be firmly and smoothly combined, but also that the edge banding must be combined with other The joints of the surfaces should not have defects such as bottoming, chipping, and large gaps, and the transition should be natural, smooth and smooth.
Third, extend the service life of office furniture
The precise edge sealing design of the board can prevent water or other liquids from entering the board, avoiding the expansion, deformation and breeding of bacteria on the desktop, thereby prolonging the service life of the office furniture, and the office furniture after the edge sealing treatment is also more expensive in terms of cleaning easy.
Fourth, avoid sharp edges and corners from hurting people's bodies
The general edge banding will use the dull edge banding design to smooth the corners of the table, thereby reducing the damage to the body by the sharp corners
