Use of aluminum alloy heater
JRD2/50W-500W series aluminum alloy electric heater new heater. The heater is made of professional aluminum alloy heat-dissipating material and high-quality electric heating wire. The utility model has the advantages of small volume, uniform heat dissipation, fast heat conduction, large heat dissipation area and beautiful appearance, thereby ensuring that the service life of the heating wire is much longer than that of the general tubular heater, and the utility model can work reliably for a long time. In addition, the heater has the characteristics of high insulation strength and simple installation. With the temperature and humidity monitor, it can realize the automatic control of moisture and anti-condensation heating control of electric power.
JRD2/50W-500W series aluminum alloy electric heater technical specifications working voltage:
AC110V, 220V, 380V or DC220V, 380V (customer selects according to demand)
JRD2/50W-500W series aluminum alloy electric heater working frequency:
50Hz (only for AC voltage) Insulation resistance: >50M ohms Electric strength: >2000V (between terminal and aluminum medium) Continuous working time: >5000 hours Rated power: 50~500W
JRD2/50W-500W series aluminum alloy electric heater This series of products are mainly used for electric equipment (such as terminal box, high and low voltage control cabinet, hand truck type switch cabinet, ring network switch cabinet, box type substation, circuit breaker mechanism box, instrument Boxes, etc., as well as other occasions where it is necessary to control the temperature and humidity of the environment, to protect and ensure the efficient and safe operation of automation of power equipment, reduce costs and improve economic efficiency. The products are produced by Hunan Sanda Electronic Technology Co., Ltd., which can be used for a long time under strong electric field, strong magnetic field and various harsh natural environments.

Plant extraction process
1. Select plants/herbs. No more than ancient prescriptions, prescriptions, folk herbs to find. At present, common and uncommon herbs have been studied. At present, it is mostly to increase the amount of medicinal materials to extract and separate components with low content, or to find medicinal plants that have never been studied from miao medicine, Tibetan medicine, Mongolian medicine, Africa, Latin America and other places.
2. The extraction. Solvent petroleum ether, n-hexane, cyclohexane, benzene, chloroform, ethyl acetate, n-butanol, acetone, ethanol, methanol, water (low polarity → high polarity). Daily medicine decoction effective, water and ethanol and other solvents with large polarity, such as artemisinin boiling ineffective extraction with petroleum ether and other solvents with small polarity. Common medicinal materials water/alcohol/ether to go through, separation and identification of more compounds.
3. The separation. This is the most important work. In the solution extracted from the second step, there are dozens of compounds, usually by column chromatography, which is often referred to as the column flushing. It's a lot of work, it's boring, it's low tech. A master's student might do this every day for two years. The column for separating compounds, as shown below, is as large as 2 meters high and as small as 10 centimeters. Change the solvent condition of mobile phase, change the material of column, different conditions and different separation principles of column repeatedly punching, can be separated from the monomer compound.
