Companies registered capital of 35 million yuan, the end of 2014 the total assets of 48.69 million yuan, including fixed assets of 37.52 million yuan. The company's existing cooperation Orange cultivation base 7043.5 acres, the company production base is located in Jiangxi County Tech Industrial Park Chu Tan industrial area, covers an area of 120 acres, it has built a standard plant 9,000 square meters, Nissan 6000 kg Orange enzymes and other liquid enzyme products. Enzyme, known as enzyme, refers to a polymer substance having biocatalytic functionality. In the catalytic reaction system an enzyme, the reactant molecules are known as substrates, enzyme substrates by catalytic conversion to another molecule. Almost all cellular activity of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts, enzymes chemical reactions by lowering the activation energy to accelerate the rate of the reaction, most of the enzyme catalyzed reaction rate can be increased a million times; in fact, the enzyme is to provide an activation energy needs than another low way, so that more particles to have less than the activation energy of the reaction kinetic energy, thus speeding up the reaction rate. Enzyme as a catalyst, in itself is not consumed during the reaction, it does not affect the chemical equilibrium reactions. Positive enzyme catalysis, but also a negative catalytic effect, not only to accelerate the reaction rate, but also to reduce the reaction rate. And other non-living catalysts is different, having a high degree of specificity of enzyme, only a catalytic reaction or produce a particular specific configuration.

1. The hardness of two kinds of objects is different: for example: a high hardness abrasive can cut both fast and deep 2. Particle size (abrasive grain size): eg: large number of sand grains can be cut fast and deep 3. adhesion between sand grains, sand and bonding Agent bonding and sand and matrix bonding: in the grinding process, these factors determine the time it takes for the abrasive particles to fall off the abrasive surface and how long it takes for the exposed surface of the processed object to reach the new abrasive particles.
4. Contact pressure: More pressure causes grinding to be faster.
5. Abrasive clogging: During the grinding process, the grinding tool peels off the debris of the processing piece to block the abrasive grain gap, thereby increasing the friction and reducing the grinding effect.
6. Use lubricant, heat sink or metalworking fluid: removing the waste in time during the grinding process can effectively avoid the blockage of the abrasive. The excellent thermal conductivity of the lubricating fluid or the heat dissipating agent can directly affect the physical grinding tool itself of the processing component. An effective solution can be to use a substrate or substrate heat sink, or to suspend the process, or to use a finishing process to process the part.
Six factors that affect the grinding effect of the machined object
The following factors may affect the grinding effect of the machined object:
