LED explosion-proof grille lamp Haowangte design, Suzhou Haowangte Lighting Co., Ltd. specializes in producing [300*600LED explosion-proof grille lamp, 600*600 explosion-proof grille lamp, 300*1200LED explosion-proof grille lamp, 600*1200LED explosion-proof grille Lights and other explosion-proof lamps of various specifications; what is the explosion-proof performance of LED explosion-proof grille lamps? The explosion-proof performance of LED explosion-proof grille lamps is completely different from the performance of various explosion-proof lamps commonly found on the market; the details are as follows: 1. The LED explosion-proof grille lamp housing is all made of steel plate; the protection performance is only IP23. 2, the sealing performance can not reach the performance of our conventional LED explosion-proof lamps. The explosion-proof performance of the LED explosion-proof grille lamp produced by our company is special treatment of the ballast. When the spark or harmful gas is encountered, the ballast will not explode; so many users and dealers do not understand the LED explosion-proof grille lamp. How is the explosion-proof; therefore, the LED explosion-proof grille lamp can not be completely used in a number of dangerous places such as Zone 1, Zone 2; only in some ordinary places such as office buildings, banks, hospitals, etc. [LED explosion-proof grille lamp] opening size is as follows: 1, 300*600LED explosion-proof grille lamp opening size: 295*595 corresponding power: 2*8W LED 2, 600 * 600 explosion-proof grille lamp opening size: 595 * 595 corresponding power: 3 * 8W LED 3, 300 * 1200 LED explosion-proof grille lamp opening size: 295 * 1195 4, 600 * 1200 LED explosion-proof grille lamp opening size: 595 * 1195 Detailed LED explosion-proof grille lamp power Please pay more attention to Suzhou Haowang Special Lighting Co., Ltd.!
Plant extraction process
1. Select plants/medicinal materials. It is nothing more than ancient prescriptions, proven prescriptions, and folk medicinal herbs. At present, common and uncommon medicinal materials have been studied. Most of the time, the amount of medicinal materials has been increased to extract low-isolated components, or medicinal plants have not been studied from Miao medicine, Tibetan medicine, Mongolian medicine, Africa, Latin America and other places.
2. Extract. Solvent petroleum ether, n-hexane, cyclohexane, benzene, chloroform, ethyl acetate, n-butanol, acetone, ethanol, methanol, water (small polarity → large polarity). Daily decoction of medicines is effective, use water and ethanol and other solvents with high polarity. Artemisinin and other boiling methods are not effective, use petroleum ether and other solvents with low polarity. The common medicinal materials, water/alcohol/ether, are presented again, and more compounds can be separated and identified.
3. Separation. This is the most important task. There are dozens of compounds in the solution extracted in the second step. Generally, column chromatography is used, which is what we often call column flushing. The workload is large, boring, and low-tech. A master's degree may do this every day for 2 years of experimentation. As shown in the figure below, the column for separating compounds is as large as 2 meters high and as small as 10 cm. Change the solvent conditions of the mobile phase, change the material of the column, and repeatedly wash the column under different conditions and separation principles to separate the monomer compound.
