The vacuum drying oven is specially designed for drying heat-sensitive, easily decomposed and easily oxidized substances. It can maintain a certain degree of vacuum in the work room and can fill the interior with inert gas, especially for some items with complex components. Fast drying, using intelligent digital temperature controller for temperature setting, display and control. What preparations need to be done before using the vacuum drying oven? 1. The vacuum drying oven oven is placed on the indoor dry ground and work surface, and no other fixing devices are required. 2. A knife or an air switch should be installed in the power supply line for the exclusive use of the vacuum drying oven, and a wire with a thickness twice the cross-sectional area of the power cord should be used as the grounding wire. 3. Before powering on, check the electrical performance of the vacuum drying box, and pay attention to whether there is an open circuit or leakage. 4. When everything is ready, you can put in the test sample, close the door of the vacuum drying box, and open the exhaust valve if necessary, with a gap of about 10mm. 5. After connecting to the power supply, the heating switch can be turned on, and the HASUC vacuum drying oven will turn the temperature setting dial to the required working temperature value. 6. Pay attention to the standardization of operation. 7. When the temperature rises to the required working temperature, adjust until the green light turns off, and then make fine adjustments until the green light turns on again. The constant temperature point is where the light turns on and off alternately. At this time, the knob can be fine-tuned until the green light turns off. Keep it at a constant temperature (it is likely that the temperature will continue to rise at a constant temperature, which is due to the influence of residual heat, and this phenomenon will stabilize in about half an hour). When the temperature in the working chamber of the vacuum drying oven is stable (the so-called "constant temperature state"), the temperature controller can be adjusted slightly to improve the accuracy of temperature control, and any working temperature can be selected by this method. 8. When the vacuum drying oven is at a constant temperature, the high temperature switch should be turned off, and only one set of electric heaters should be left to work, so as to avoid excessive power and affect the constant temperature accuracy. When the working temperature is less than 150 ℃, only one set of heaters should work, and the high temperature switch should be turned off.

After the Muffle Furnace has been used for a long time, there may be some failure problems, which will affect the use. However, as long as it is a fault, there will be a solution, so today we will teach you four solutions to the failure of the Lab Muffle Furnace: 1. The furnace does not heat up Solution: The power supply voltage is normal, the controller works normally, the ammeter has no display, and the common fault is that the electric furnace wire is open circuit. You can check it with a multimeter and replace it with an electric furnace wire of the same specification. If the power supply voltage is normal and the controller cannot work, you can repair the switches, fuses and the travel switch of the furnace door inside the controller. If the furnace door of the electric furnace is not closed and the controller cannot work, please refer to the controller manual for the maintenance method of the controller failure. 2.The furnace heats up very slowly Solution: The power supply voltage is normal, the controller works normally, and the common fault is that part of the electric furnace wire is disconnected. You can check it with a multimeter and replace it with the same specification of the electric furnace wire. The power supply voltage is normal, but the working voltage of the electric furnace is low. The reason is that the voltage drop of the power supply line is too large or the contact between the socket and the control switch is not good, which can be adjusted and replaced. The power supply voltage is lower than the normal voltage, and the heating power of the electric furnace is insufficient. The three-phase power supply is out of phase, which can be adjusted and repaired. 3. The furnace temperature is abnormal Solution: The reason for this is that the thermocouple is not inserted into the furnace, causing the furnace temperature to be out of control. The graduation number of the thermocouple is inconsistent with the graduation number of the temperature control instrument, which will cause the furnace temperature to be inconsistent with the temperature displayed by the temperature control instrument. 4. The furnace door is not well sealed Solution: The reason for this situation is that the spring is loose. It is only necessary to adjust the spring positioning screws on both sides of the furnace door to replace the spring. ACEY provides different kinds of Lab Furnace.

Button cell (buttoncell) is also called a coin cell. In terms of appearance, it refers to a battery with a size like a small button. Generally speaking, the diameter is larger and the thickness is thinner. The corresponding battery classifications include cylindrical battery, pouch battery, prismatic battery. Here are the step and process of coin cell： battery preparation： 1. Preparation of active materials by rotary kiln sintering 2. Mix and grind the prepared materials 3. Vacuum stirring the prepared positive and negative electrode mixture 4. Use a viscometer to measure the viscosity of the slurry when the coating effect is better, and record it so that the battery slurry can be adjusted to this viscosity in the next experiment 5. Use a slurry filter device to filter out various hard particles with a particle size of not less than 124 microns in the slurry 6. The positive and negative electrode materials are respectively coated on the current collector and dried 7. Roll the dried positive and negative substrates to reduce the thickness and increase the density. 8. Move the pole piece into the drying box for further drying battery packaging 9. Cut the positive and negative electrode sheets and separator paper into small circles with the specified diameter 10. Move the cut pole piece, separator paper, electrolyte, battery case and other accessories into the glove box (water oxygen content should be less than 11PPM) 11. Assemble the batteries in the order of stacking from bottom to top and inject the electrolyte: negative electrode shell > flat pad + appropriate amount of electrolyte > metal lithium sheet + appropriate amount of electrolyte > one layer of separator paper + appropriate amount of electrolyte > positive electrode + appropriate amount of electrolysis Liquid>Flat pad+Appropriate amount of electrolyte>Shrapnel>Positive shell 12. Encapsulate the battery on the encapsulation machine battery test 13. Use a battery analyzer to test the battery capacity and cycle aging 14. Use an internal resistance tester to measure the internal resistance of the battery The battery shells of the commonly used button batteries are CR2032, CR2025, CR2016, etc., C stands for the button battery system, and R stands for the round shape of the battery. The first two digits are the diameter (unit mm), and the last two digits are the thickness (unit 0.1mm), whichever is closer to the two. For example, the approximate size of CR2032 is 20mm in diameter and 3.2mm in thickness. ACEY provides the whole line of coin cell lab equipment.

    70% of the quality of the battery is related to the quality of the pole piece, and 70% of the quality of the pole piece is related to the quality of the slurry. Therefore, a good slurry is equivalent to half of a battery, and homogenization is the primary and core task of battery manufacturing. Laboratory cell processes tend to be more elaborate than commercial cell processes, except for the homogenization process. This also shows that homogenization is also a difficulty in battery manufacturing.      The main purpose of slurry dispersion of lithium ion batteries is to uniformly disperse active materials, conductive agents, binders, etc. in a solvent according to a certain mass ratio to form a stable slurry with a certain viscosity, which is used for the coating of pole pieces. The purpose of the lithium-ion battery pulping process is to prepare the film for production. The requirements of the pole piece for the ideal slurry:  1. The active material particles are fine and uniformly dispersed without agglomeration, the conductive agent particles form a thin layer and dispersed into a conductive network, and a large number of active material particles are interlocked and connected on the current collector.  2. The particles of the active material are small, which makes the battery have a high current density.\       At present, the mainstream homogenizing equipment used by lithium-ion battery manufacturers is a double planetary mixer. The double planetary mixer used in the lithium battery industry, also called PD mixer, is equipped with a low-speed stirring part Planet and a high-speed dispersing part disper. The low-speed stirring components are two bent-frame stirring paddles, driven by planetary gears. The paddle rotates when it rotates, so that the material moves up and down, left and right, so as to achieve the ideal mixing effect in a short time. The high-speed dispersing part is generally a toothed dispersing disc, which revolves with the planet carrier and rotates at a high speed at the same time, so that the material is strongly sheared and dispersed. Its effect is several times that of ordinary mixers. The dispersion part is divided into monodisperse shaft and double dispersion shaft. Dispersion axis.     The preparation of slurries in twin planetary mixers often utilizes shear forces generated by hydrodynamics, which are governed by flow shear rate, cluster cross-sectional area, and hydrodynamic viscosity. The preparation of the slurry generally involves two processes: the breakup of the clusters and the reorganization of the suspended aggregates.     ACEY NEW ENERGY provides different kinds of battery material mixing machine.

    In the daily use of the planetary ball mill, the excessive wear of the grinding balls will not only increase the cost of the grinding balls, but also have a negative impact on the quality of the material output, so we should try to reduce the wear of the grinding balls.     When the planetary ball mill is running, the grinding balls will continuously collide and rub against the material, the inner wall of the ball mill, and the grinding ball itself, which in turn leads to the wear of the grinding ball. Excessive wear of grinding balls will not only increase the cost of grinding balls, but also adversely affect the quality of material output, so we should try to reduce the wear of grinding balls.     To reduce the wear of the grinding balls of the planetary ball mill, we must first know what factors affect the wear of the grinding balls? These factors can be roughly summed up as follows:     The size, ratio and loading of grinding balls: The quality of grinding balls will change with the size. At a certain speed of the planetary ball mill, the greater the quality of the grinding balls, the greater the impact. When configuring the size of the grinding balls, the collision probability between the grinding balls of the same size is higher, and the grinding balls are prone to fatigue wear, and the loading of the grinding balls will also affect the collision probability between the grinding balls.     The size and speed of the planetary ball mill: the larger the planetary ball mill, the larger the diameter of the ball mill tank, the movement speed of the grinding ball will increase accordingly, and the impact will also become larger, which will accelerate the wear and tear. The same is true for speeding too fast.     Types and properties of grinding balls: The wear conditions of different grinding balls vary with density, hardness, elasticity, wear resistance and acid and alkali resistance.     The properties of the grinding material of the planetary ball mill: the hardness, brittleness, shape and size of the material have an extremely important influence on the grinding process of the grinding ball.     ACEY provides different kinds of lab ball mill.
