The company recently announced the May sales and sales bulletin. According to the announcement, in May 2009, the company sold a total of 8,171 vehicles, a 5.6% drop from the previous month and a 22% year-on-year decline. From January to May 2009, the company sold a total of 32,000 vehicles. Accumulated a year-on-year decline of 17%; cumulative production of 40,000 vehicles, a cumulative decline of 10.2% year-on-year. The difference between production and sales is about 8,300 units, indicating that the consumption structure is still mainly dump trucks (dumping vehicles, or construction vehicles generally need to enter the terminal market through the conversion plant, and the time for conversion brings the difference between production and sales). The demand for heavy trucks for logistics and transportation has not yet recovered significantly.
Growth in fixed asset investment hits a 5-year high and monthly sales of semi-trailer tractors continue to rise
The recent increase in fixed asset investment announced by the National Bureau of Statistics significantly exceeded market expectations. Data show that from January to May in 2009, urban fixed asset investment was 5.35 trillion yuan, a year-on-year increase of 32.9%. The growth rate of fixed asset investment increased from 30.5% in January to January to 32.9% in January to May. In May, the year-on-year increase in fixed asset investment surged to 39%, a record high in five years.
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.
