The application of thiourea (CS(NH₂)₂) in photography is mainly reflected in the traditional black and white film development process. As an auxiliary contrast agent, thiourea can improve the development and enhance the quality of photos. Here are some specific applications of thiourea in photography:
Thiourea, also known as thiourea (CAS number: 62-56-6), is generally a colorless orthorhombic crystal. Due to the presence of lone pair electrons on sulfur and ammonia atoms in thiourea molecules, they can form coordination compounds with various metal ions, but the coordination constants are generally small. It is worth noting that due to the special affinity of sulfur atoms in thiourea for precious metals, it often forms stable coordination compounds with precious metals, making it widely used in electroplating and chemical plating of precious metals.
The use of thiourea (CS(NH₂)₂) in alkaline cleaning agents can bring a variety of benefits, especially in the field of metal finishing and industrial cleaning. Here are some of the main advantages of thiourea in alkaline cleaners:
Thiourea, also known as thiocarbamide or sulfourea, is an organic chemical product. Thiourea is widely used in pesticides. Thiourea has the following three physiological functions in plants:
Thiourea (CS(NH₂)₂) is widely used as an additive in the electroplating process, especially in the electroplating process of metals such as gold, silver, copper, etc. The application of thiourea can significantly improve the quality and performance of electroplating layers. Here are the main differences between thiourea used and not thiourea used in the electroplating process:
Thiourea (chemical formula CS(NH₂)₂) is mainly used in beneficiation as a flotation inhibitor, leaching agent or metal complexing agent, and its action depends on its unique chemical properties (coordination capacity of sulfur and amino groups). Sinhon Chem is the leading thiourea production plant in China, with an annual output of 20,000 tons, and its products are widely used in large mines in China, Russia, Uzbekistan, Africa and South America. The following are the specific applications and reaction principles of thiourea:
