Copper Clad Laminate Industry

The full name of copper clad laminate is copper clad laminate, referred to as CCL in English. It is a plate-like material made of wood pulp paper or glass fiber cloth, which is impregnated with resin glue, coated with copper foil and hot pressed. Copper clad laminate mainly plays the role of mutual conductivity, insulation and support for PCB. It is the main material for processing and manufacturing printed circuit board (PCB). Its performance plays a decisive role in the transmission speed, energy loss and characteristic impedance of PCB. It is widely used in 5G communication, HDI high-density interconnection circuit, chip IC carrier board, automotive electronics, household appliances and other fields.

Copper Foil Industry

Electronic grade copper foil industry is an important basic industry of electronic information industry. Electronic grade copper foil is copper foil with purity of more than 99.7 and thickness of 5μm-105μm, which is one of the basic materials of electronic industry. It has good electrical conductivity, thermal conductivity and mechanical processing performance, and can meet the requirements of electronic equipment for signal transmission and circuit connection. The main applications of electronic grade copper foil include printed circuit boards (PCB/FPC), lithium-ion battery anode materials, electromagnetic shielding and antistatic fields, 5G communication equipment, automotive electronics, and also widely used in consumer electronics.

Glass Fiber Industry

The electronic glass fiber industry is an important segment of the glass fiber industry. Electronic glass fiber is a kind of high-performance glass fiber with excellent heat resistance, chemical resistance, flame resistance and electrical and mechanical properties. It is mainly used in the field of electronic information and is the key basic material for copper clad laminate and other products. The production process of electronic glass fiber is more complicated. First, various raw materials such as pyrophyllite, kaolin, calcite, borocalcium, silica sand are mixed, transported to a kiln with a temperature as high as 1600 ℃, heated into glass liquid, then drawn into glass fiber monofilament at high speed by platinum leakage plate, and finally made into glass yarn by twisting and other processes.

Environmental Protection Industry

The industrial VOCs waste gas treatment industry is an environmental protection industry that has emerged in response to the volatile organic compounds (VOCs) waste gas generated in the industrial production process. VOCs are one of the important precursors for the formation of ozone (OZ1) and fine particulate matter (PM2.5). With the acceleration of industrialization and the increase of energy consumption, the emission of industrial VOCs is rising, which has a serious impact on the quality of the atmospheric environment, causing photochemical smog, haze and other environmental problems. Some VOCs are toxic, carcinogenic and teratogenic, and pose a threat to human health. Long-term exposure to VOCs may lead to respiratory diseases, nervous system damage, liver and kidney damage. In order to strengthen the governance of industrial VOCs, the state and local governments have issued a series of policies, regulations and emission standards. For example, the "Air Pollution Prevention and Control Law" and "Unorganized Emission Control Standards for Volatile Organic Compounds" have strictly restricted and supervised the emission of VOCs from industrial enterprises. The introduction of these policies and regulations provides strong policy support and legal protection for the development of industrial VOCs waste gas treatment industry.
