According to reports, the machine uses advanced Cummins NT855C engine, strong power, reliable quality, small amount of pollution, environmental protection increased. The engine terminal is equipped with a damping device, which improves the service life of the transmission components. The machine combines the advantages of the TY220 bulldozer (National Gold Award product), adopts advanced hydraulic transmission and hydraulic control technology, and is maneuverable and flexible, with advanced and reasonable structure. With a large-capacity and high-efficiency working device, the fence-type blade structure can effectively prevent the drift of the suspended material, and the increase of the side plates on both sides is more conducive to the collection of garbage. In addition, the cab is equipped with air conditioning and sealed devices, which can effectively reduce noise and give the driver a comfortable working environment. (Source: China Construction News)
Tert-Butyl Peroxy Benzoate Catalysis
TBPB is a low volatility ,high purity,liquid, aromatic peroxuester.it is effective as medium of a broad spectrum of monomers e.g .styrene.ethylenn,acrylics.it is also used to cure (copolymerzation) unsaturated 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.
