Seven ways to reduce noise in tractors
1. Make sure that the tractor is always working in a good technical condition.
2. To ensure the complete and reliable operation of the tractor components, especially to install the exhaust pipe, because the exhaust pipe is mostly equipped with muffler, it will reduce a large part of the noise.
3. To prevent parts from loosening, loose parts can cause vibration.
4. Do a good job in the maintenance inspection of tractors. Add qualified lubricants and greases as required to prevent poor lubrication of relative moving parts and produce dry friction or semi-dry friction and increase noise.
5. To maintain a good fit clearance of the relative moving parts, according to technical requirements for assembly or adjustment.
6. Do not arbitrarily change the fuel supply. If the fuel supply becomes larger, the fuel injected into the cylinder will not be completely burned. This will not only waste fuel, pollute the air, but also increase the noise of the tractor.
7. The advance angle of fuel supply should be adjusted accurately. Because the accuracy of fuel supply advance angle adjustment will not only directly affect the performance of tractor power, but also affect the size of tractor noise. For example, when a tractor emits extremely loud sounds of exhaust gas, it is often accompanied by a "bang and bang" sound, which is caused by an excessive feed angle.
Sodium Hyaluronate is very important for skin because it improves moisturization, maintains skin resilience, and reduces damage in the lower part of skin when the skin is damaged. It also acts like lubricant by causing collagen, a main constituent of skin, to move smoothly in between cells.
But from the age of 25, Sodium Hyaluronate in human body will lose gradually, only remaining 65% of young skin at the age of 30, only 25% of young skin at the age of 50.
With the increase of the age and the loss of Sodium Hyaluronate, the skin will lose elasticity and luster, aging, wrinkles and relaxation will be generated gradually.
Sodium Hyaluronate is so water-friendly and it has functions of the best moisturizing factor and prevents diseases such as skin infections by preventing the penetration of external substances such as bacteria.
Therefore, it is regarded as an ideal "natural moisturizer" factor and widely used in cosmetics that suitable for different skins, climates and environments.
High molecular Sodium Hyaluronate can be formed breathable film on the surface of the skin, help the skin to lock moisture, and to prevent the invasion of bacteria, dust and ultraviolet, so that to protect the skin from damage.
Low molecular Sodium Hyaluronate, which is designed for better skin penetration, can penetrate into the dermis quickly, dilated capillaries slightly, promote blood circulation and metabolism, and so it has function of eliminating wrinkles, increasing skin elasticity and preventing skin aging.
