According to statistics, the total net profit of listed companies in the coal sector during the first half of this year was 30.121 billion yuan, compared with 17.791 billion yuan in the same period of last year, and the overall performance of listed companies in the coal sector increased by 69.31% over the same period last year. According to statistics from Tianshen Investment, the total net profit of listed companies in the first half of the year was 553.3 billion yuan, a year-on-year increase of 16.03%. It can be seen that the growth rate of the net profit of listed companies in the coal sector is higher than that of the A-share listed companies.
Price increase is the main reason for the sharp increase in the performance of coal stocks in the first half of this year. Although listed companies in the coal industry performed well in the first half of the year, such stocks were “slumpingâ€. According to the analysis, the recent decline in coal stocks was mainly suppressed by international oil prices and market demand. Sun Haibo, a research fellow at United Securities Securities and Coal Industry, believes that the decline in international coal prices and oil prices triggered a second decline in coal stocks. On the demand side, as the production speed of downstream products such as thermal power, crude steel and cement continued to decline in the first half of this year, fixed investment in coal continued to grow rapidly.
Coal stocks have fallen collectively in recent days, and they have plummeted on the 5th. The overall decline has exceeded 5%. However, industry analysts pointed out that although the coal stocks fell in the short-term, but these do not affect the long-term investment in coal stocks. Xiao Hanping, an analyst at Galaxy Securities, believes that selling a small number of funds in the short-term will also cause a follow-through to sell in the weak market.
Oil/water heating,stirring/mixing, distillation, reflux
Feature:
1.GG17 high-borosilicate glass with nice physical-chemical properties; experiment temperature -100 to 400 degree C; Resistant to strong acidic properties of materials; only touching with glass parts & PTFE, no cross-contamination.
2. Precision Mechanical seal stirring to keep high vacuum degree.
3. Glass(PTFE)discharge valve, no-dead angle mixing, fast no residue discharge.
4. Frequency control speed gear motor, smooth running,high torque, automatic booster , no spark, noise free, long life.
5. SUS frame and cast aluminum material kettle body support, simple as well as strong; stable structure
6.Circulating water/oil bath, Heating Mantle can supply the heating origin; Cooling mode machine:Cool Chiller, convenient and practical
7. Scientific & innovative structure, practical, strong.
Usage
Heating principle
Through the heating coil in the tank heat the transfer medium-water or oil heating,(or heating the kettle body by heating mantle directly). Then the transfer medium pass its hot energy to reaction materials in the kettle.Constant temperature heating and stirring can proceed simultaneously.
Range:It can do all kinds of biochemical reactions and synthesis reactions at a constant temperature condition. It is also a colsed system on the whole.
Circulating Water Vacuum Pump can pump into the reactor sorts of liquids and gases. The reflux or distillation is possible under different temperature state.
1.Please check whether the glass kettle intact or not, whether each interface is consistent or not. Please handle with care.
2.Wipe each interface with a soft cloth (napkin available),then apply a little vacuum grease.( Vacuum grease must be covered to prevent gray sand from entering after using.)
3. Each interface can not be over-tightened, loosening them periodically, avoid long-term furrowed
causing connector tightened deadly.
The overall performance of the coal industry increased by 70%
Recently, coal stocks have become the object of market slump. Among them, Xishan Coal & Electricity (000983) has fallen by more than 20% since September and has been significantly reduced by institutions. It also followed the broader market crash on Friday, with the overall decline exceeding 5%. The 2008 mid-year report showed that the overall performance of coal stocks increased by 70% in the first half of this year.
