There is a sensor in the trash can, which automatically turns on the device to compress garbage when the load reaches a certain level Maybe it is the habit of using and developing! The trash has become an indispensable item in people's lives. Recently, the United Kingdom began the first trial of solar energy trash. This new type of trash can use the solar energy to compress the garbage. Its capacity is 8 times that of ordinary trash can. It can be called the "large stomach king" in the trash can. According to foreign media reports, solar trash cans were placed in the Green End Road park in Cambridge. Once this experiment is successful, it will bring about a new round of environmental technology revolution. The new type of trash can not only reduce the carbon content of the garbage, but also has a large garbage capacity, which will inevitably reduce the burden on cleaners. Bob Carter, director of the Streets and Open Spaces at Cambridge City Council in Cambridge, said: "This new type of trash can only require a small amount of sunlight to compress the trash. There is a sensor in the new type of trash. When the load reaches a certain level, the device will automatically start to compress the garbage. The current test results are very satisfactory. It is believed that it will soon become the mainstream trash can in the UK." According to the department’s report, the solar waste bin can hold 800 liters (about 0.8 cubic meters) of garbage after using a compression device. The power of its compression device is mainly derived from a 12-volt solar cell. In addition, according to Clare Blair, who is investing in the solar energy trash project, solar trash has been widely used in the United States because it can compress the carbon content of waste products, which can effectively protect the environment. In addition, when the bin is full, it will automatically send an e-mail to the cleaners to clean up the garbage.
(1) Diamond pen dressing grinding wheel: According to the size of diamond particles and their distribution in the pen, diamond pens can be divided into several types, such as chain and powder. The alloy with strong bonding force is used as the bonding agent, so the diamond grinding wheel particles are not easy to fall off during use, so there is no need to repair the grinding process.
(2) Grinding wheel dressing by rolling method: Diamond grinding wheel dressing by rolling method. Grinding wheel drives the rolling wheel at the speed of 1~2m/s by reducing the speed
Made of, carbide or abrasive) rotary. The pressure of rolling wheel applied to grinding wheel is about 3~5MPa, grinding the surface of diamond grinding wheel
Make the abrasive particles fall off. The grinding wheel dressing by rolling method has better cutting performance and lower cost, but the surface roughness of the grinding part is rougher and rolling
Damage, short life, easy loss of precision. Therefore, this dressing method is mainly used for forming grinding with small batch size and low precision.
Green silicon carbide or ceramic white corundum is used for dressing. Dressing ring is the first choice for dressing diamond grinding wheel or CBN grinding wheel. It is sharp in dressing, not easy to remove sand and has high dressing efficiency.
