Dicyandiamide with a purity of 99.8% is a high-purity organic compound, which we call electronic grade dicyandiamide. This high-grade dicyandiamide has important applications in the electronics industry, especially in the production of epoxy resin copper clad laminates. Due to its excellent insulation properties, electronic grade dicyandiamide is widely used as a curing agent in the process of impregnating glass cloth with resin for copper clad laminates.

Ethylenethiourea has anti-hypoxia activity and is used as an intermediate in the synthesis of famotidine (a drug used to treat hyperacidity and peptic ulcers). It can be used as an organic synthesis intermediate and pharmaceutical intermediate, and can be used in laboratory research and development processes and chemical production processes.

Among numerous black paints and inks, acetylene black is an excellent choice of black pigment. Take automotive repair paint as an example; it can give the repaired area a deep and pure black effect, making it precisely match the color of the original car paint. This is due to the characteristics of acetylene black as a high-pigment carbon black. Its small particle size and large specific surface area allow it to absorb and scatter light very effectively, resulting in an extremely rich black tone. In high-end ink products used for printing high-quality book covers or art albums, the addition of acetylene black can effectively ensure the depth and saturation of the black ink color.

In terms of conductivity, high-quality acetylene black has fewer impurities and a higher degree of graphitization, allowing it to better form a conductive network and enhance the conductivity of the battery electrode. This facilitates the rapid transfer of electrons during high-rate discharge, reducing the internal resistance of the battery. Poor-quality acetylene black, however, may contain more impurities, which can interfere with the formation of the conductive network, leading to increased internal resistance and reduced discharge performance.

Acetylene black, as a crucial industrial material, plays a significant role in numerous fields, especially in electrochemical applications such as lithium thionyl chloride batteries. The relationship between its oil absorption value and electrical conductivity is close and subtle, profoundly impacting the performance of related products.

Acetylene black plays a crucial role in lithium-ion batteries. Its unique chain-like structure enables the construction of an efficient conductive network within the electrode materials, significantly improving conductivity. When added to both positive and negative electrode materials, it acts as an 'electronic bridge', accelerating electron movement and reducing internal resistance. For example, adding acetylene black to a lithium iron phosphate positive electrode significantly reduces internal resistance, improving power density and charge-discharge efficiency, allowing the battery to output electrical energy more efficiently during discharge.

Reducing water pollution: Dicyandiamide can inhibit the transformation of ammonium nitrogen to nitrate nitrogen, reducing the possibility of nitrate nitrogen loss with water flow. After nitrate nitrogen enters the water body, it will cause eutrophication of the water body and trigger a series of environmental problems such as excessive algae reproduction. The use of this long-acting nitrogen fertilizer can effectively reduce the amount of nitrogen leaching into the water body, which is of positive significance to the protection of surface water and groundwater quality.

Dicyandiamide can inhibit the activity of nitrifying bacteria in soil, thereby slowing down the conversion of ammonium nitrogen to nitrate nitrogen. This process is crucial because nitrate nitrogen is easily lost with water or through denitrification, while ammonium nitrogen is relatively stable and more conducive to plant uptake.

In cosmetics, the use of guanidine carbonate must comply with relevant cosmetic safety and technical specifications. Its concentration is strictly limited to ensure product safety under normal use conditions. In the pharmaceutical field, when used as a pharmaceutical intermediate, etc., there are also corresponding quality standards and impurity limits.
