Let's take a closer look at the order of manipulation of the glass reactor:
1. Check that the power supply voltage is consistent with the specifications provided on the machine nameplate.
2. Plug in the power plug, turn on the power switch on the inverter, and use the speed control knob to select the appropriate speed.
3. The activity of the material and the power of the motor speed may resonate at a certain point. Please change the speed of the motor to avoid resonance.
4. After the stir bar is installed, it must be rotated by hand to pay attention to whether the concentricity is good. If the heart is not good, the heavy clamp should be loosened. After the clamp is turned on, turn on the power and adjust gradually from slow to fast.
5, using the stir bar regulator, you can make the stirring leaves up and down 5cm as needed.
6. If the sealing performance of the kettle is found to be degraded, please check the rotary bearing in the agitator sleeve.
7. The glass equipment of the reaction device is all made of GG.17 low expansion coefficient high temperature resistant borosilicate glass. The user should self-fit glass bottles such as reaction bottles. Please confirm the glass material to ensure safe use.
8. The external layer of the interlayer on the glass kettle can be heated by the hot oil. The coolant can be used for low temperature reaction. If it is heated by steam, it should not exceed 0.5K-1K. (Try not to use pressure steam to heat).
9. When the test is carried out at low temperature, the discharge valve at the bottom will be frosted. When using the valve, it must be partially thawed to prevent the glass from being broken.
10. If there are particulate objects in the solution during use, it is possible to store the remaining materials on the PTFE piston of the valve. When used again, the airtightness will be affected. Be sure to clean and re-use each time after discharging. .
Highway fog lights
Many highways use traffic lights and fog lights. The products of highways are actually stable and durable. It can`t be said that one product can be used for one year. The highway is a major investment in a national infrastructure project. If each product is only used for one year, it is really too much waste. Therefore, when choosing highway electromechanical products, especially 304 stainless steel fog lamps, 304 stainless steel is used, it is best to choose the best materials. If you do this, you might get a little more money at the beginning, but in the end he will achieve completely different results.
Stainless steel fog lights and traffic lights,
Many expressway electromechanical projects have been noted during the bidding. The lights at the entrance of the expressway must be made of stainless steel and made of primary colors, that is, its color does not need to be sprayed. Why? Because the material of 304 is relatively good, then 304 will not rust. After many years, its color will be as smooth as new. Therefore, this material has a very good quality for the entire highway mechanical and electrical product entrance, passage entrance and exit. Big one system improvement
Iron fog lamp
Are there any traffic lights and fog lights made of iron or plastic? The answer is yes. For many highway electromechanical projects, the owners themselves need very good things, but after bidding, after layer by layer, 316 stainless steel will change. It becomes 304, 304 stainless steel becomes an iron box, and the iron box finally becomes a plastic material. In fact, this is very bad.
What is 304 stainless steel? Stainless steel refers to a kind of stainless steel that is not easy to rust under normal conditions, and its surface is the original color, which means that it is black and white, and looks very high-grade, just like the stainless steel seat you see in an airport. The chair is the same, so the stainless steel is made into stainless steel fog lamps and stainless steel traffic lights, it looks very beautiful, and then after the surface is drawn, it looks even more high-end and high-end.
How many years can 304 stainless steel traffic lights and 304 stainless steel fog lights last? 304 stainless steel fog lights, 304 stainless steel traffic lights, they can basically be used for 5 to 8 years, because why, the shell will not rust, and the components inside will be protected after the shell does not rust. The LED itself is normal. The following can be used for 5~10 years, so the stainless steel material protects the internal components from moisture, and it will not cause damage to the internal components due to rust.
