Tert-Butyl peroxybenzoate (TBPB) a chemical compound from the group of peresters. It is often used as a radical initiator in polymerization reactions, such as the production of LDPE from ethylene, and for crosslinking, such as for unsaturated polyester resins.
As peroxo compound, TBPB contains about 8.16 wt% of active oxygen and has a self accelerating decomposition temperature (SADT) of about 60 °C. The SADT is the lowest temperature at which self-accelerating decomposition in the transport packaging can occur within a week, and which should not be exceeded while storage or transportation.[2] TBPB should therefore be stored between minimum 10 °C (below solidification) and maximum 50 °C. Dilution with a high-boiling solvent increases the SADT. The half-life of TBPB, in which 50% of the peroxy ester is decomposed, is 10 hours at 104 °C, one hour at 124 °C and one minute at 165 °C. Amines, metal ions, strong acids and bases, as well as strong reducing and oxidizing agents accelerate the decomposition of TBPB even in low concentrations.[ However, TBPB is one of the safest peresters or organic peroxides in handling. The main decomposition products of tert-butyl peroxybenzoate are carbon dioxide, acetone, methane, tert-butanol, benzoic acid and benzene.

The GJT-B series metal detector is a state-of-the-art product designed for the latest metal detection technology. This device incorporates digital phase-shifting and advanced detection techniques, ensuring high sensitivity, stable performance, and strong resistance to interference. It is widely used in industries such as thermal power, cement, paper, mining, forestry, environmental protection, and building materials, where it effectively detects metallic contaminants on conveyor belts.
Working Principle:
When metal enters the electromagnetic field of the sensor, it generates changing signals that the metal detector can detect. These signals are processed using electronic technology, and the system drives an actuating device (such as an electromagnet or motor switch) to remove harmful metals from the conveyor belt.
Timing Function: After activation, the electric relay will be delayed by 1~10 seconds before releasing.
Output Control: One pair of the electric relay’s contact points is open while the other pair is closed.
