Description

Technical Field

[0002] Silicon is one of the most abundant materials on earth. Since scientists discovered the semiconductor properties of crystalline silicon in the 19th century, it has changed almost everything, even human thinking. Until the 1960s, silicon materials have replaced the original germanium materials. Silicon materials have become the most widely used semiconductor materials because of their good high temperature resistance and radiation resistance, and are particularly suitable for making high-power devices. Most integrated circuit semiconductor devices are made of silicon materials.

[0003] The photovoltaic power generation system is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy of the photovoltaic power generation system comes from inexhaustible solar energy. It is a clean, safe and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecology, so the demand for photovoltaic power generation is increasing.

[0004] In the photovoltaic field, multi-wire cutting technology has become the mainstream technology in the large-scale production of chips and solar silicon wafers. The guide wheel is one of the key parts of the multi-wire cutting machine. The accuracy of the guide wheel determines the cutting quality of the silicon wafer. Generally, polyurethane material will be coated on the surface of the guide wheel to enhance the wear resistance and impact resistance. After coating, it needs to be dried in an oven. The evaporation of solvents at high temperatures will produce a large amount of waste gas. If it is directly discharged, it will cause great pollution to the environment. The current method of dealing with these waste gases is to collect these waste gases and then transport them to purification equipment for purification before discharging. The operation is cumbersome, and the current purification is relatively simple. Direct discharge of the purified waste gas still causes pollution to the environment.
