The annual Lunar New Year is just around the corner, here I wish the new and old customers who have been supporting and trusting us Ji kerr a happy New Year and all the best! The company's holiday arrangement for the Spring Festival in 2020 is as follows: January 18, 2020 to February 1, 2020 is the holiday time. February 2 (the ninth day of the first lunar month officially work). Finally, I sincerely wish you a happy and peaceful Spring Festival and a happy New Year! Good luck!

heat pipe (heat pipe) is the use of evaporation refrigeration, so that the temperature difference between the two ends of the heat pipe is very large, so that the heat is quickly transmitted. The general heat pipe is composed of a tube shell, a liquid suction core and an end cover. The interior is pumped into a negative pressure state and filled with the appropriate liquid, which has a low boiling point and is easy to volatilize.

The biggest advantages of the C-type pump are applicable to milligram metering, the valve body is made of all-ceramic materials, corrosion resistance, wear resistance, and measurement accuracy.

According to the agency forecast, in the next few years, smart phones calculated by 1.2 billion per year, there will be 300-400 million per year using ultra-thin heat pipe or ultra-thin soaking plate VC heat dissipation scheme; 5G base stations will also use soaking plate VC heat dissipation, according to the peak period of base station construction 1 million/year scale, VC demand is strong. At the same time, the soaking board VC is also a computer (server, laptop, tablet, etc.), game console, VR equipment, LED lamps and other cooling solution materials.

5G intelligent terminals with high-speed and large data volume operation have higher requirements for heat dissipation performance, which will promote the vigorous development of the heat dissipation market. Good heat dissipation design has become the key technology for the smooth operation of 5G equipment, and traditional heat dissipation materials such as graphite, thermal grease, and copper foil have risen in volume and price on 5G mobile phones. Two-phase liquid cooling products ultra-thin heat pipes, VC soaking sheets and other accelerated penetration into 5G and 4G intelligent terminals; Phase change energy storage thermal conductivity materials (PCM) also ushered in new development opportunities.

Chemical oxygen demand (COD) refers to the amount of oxidizing agent consumed when treating water samples with strong oxidizing agents under certain conditions, expressed in mg/l of oxygen. Chemical oxygen demand reflects the degree of pollution of water by reducing substances. Reducing substances in water include organic matter, nitrite, ferrite, sulfide and so on. It is common for water to be polluted by organic matter, so chemical oxygen demand is also one of the indicators of the relative content of organic matter.
The chemical oxygen demand of the water sample may vary depending on the type and concentration of the oxidant added, the acidity of the reaction solution, the reaction temperature and time, and the presence or absence of a catalyst. Therefore, the chemical oxygen demand is also a conditional indicator, which must be carried out in strict accordance with the operational procedures. For industrial wastewater, our country stipulates that potassium dichromate method is used, and the measured value is called chemical oxygen demand.

"The Fourth Asia Pacific Exhibition 2019" came to a close on August 18, 2019. As a high-precision ceramic metering pump enterprise focusing on research and development, design, manufacturing and after-sales service, Jickel is in line with the business philosophy of "innovation, professionalism, integrity and win-win". Full display of "high quality, high precision" in one of the micro injection pump, variable pump, large stroke injection pump. The main products exhibited by Ji kerr are single-head variable pump, double-head variable pump, milligram metering pump and other high-precision ceramic metering pump products, which are favored by new and old customers!

The device for removing bubbles from electrolyte when the battery is injected. During the injection process of the battery, we often find that tiny bubbles are generated when pushed and pulled by the injection pump. This will cause the amount of liquid injected to the electrolyte is unstable, if the difference between the upper and lower injection liquid is large, it will lead to low battery energy and high internal resistance. At present, we use mechanical physical method to stir the electrolyte to break the bubble needle and vacuum away, which should be proved that the problem of battery defoaming is greatly reduced. The basic function of this picture is to use two stainless steel pressure tanks, the first line of mechanical stirring and vacuum, when the first line of tank electrolyte to complete the mechanical stirring, the electric valve opens itself, into the second line of atmospheric pressure tank, through the Jickel liquid injection pump to extract precision injection into the battery.
