The following are some common construction plans for the reactor: ** I. Electromagnetic heating modification plan for the reactor ** 1. ** Power calculation and selection ** - First of all, the known conditions must be clear, such as the material, size (diameter, height, thickness, etc.), weight, effective volume, material weight, material mixing heat, heating temperature requirements, time requirements, etc. - According to the heat calculation formula,[Q = cm/Delta t+km](where [c] is the specific heat capacity,[m] is the mass, and [Delta t] is the temperature difference), the specific heat capacity [J/(KG* ° C)], the temperature difference [° C], and the mass [KG] are substituted into the formula and divided by the time [S] to obtain the power [W]. - For example, the known atmospheric pressure reactor, material 304, the external dimensions of the kettle body are 2 meters in diameter * 3 meters in height (8mm in thickness), the weight is about 1000kg, the effective volume is 7 m3, the material weight is 7 tons, the reaction material is a certain liquid material mixed specific heat according to the requirements of 4200J/kg* ° C, and it is required to be heated from 20 ° C to 280 ° C within 3 hours. After calculating the theoretical power, it is necessary to consider the loss (generally increase the loss by 20%) to determine the actual matching power. For example, the theoretical power of the above example is 708KW, and the actual matching is 708KW *1.2 = 850KW. Seven sets of 120KW electromagnetic heater can be used for parallel heating. 2. ** Steps to design the plan ** - Understand the original structure and working principle of the reactor, including the size, shape, material, working temperature and other parameters of the reactor. Then, according to the actual situation and needs of the reactor, the electromagnetic heating scheme was designed. ** II. Upgrade plan for the support and foam plug at the bottom of the reactor ** 1. ** Selection of Upgrade Materials ** - High-quality steel was used to ensure the bearing capacity and corrosion resistance of the lower support and foam plug. 2. ** Pre-construction preparation ** - The original lower support and foam plug were first cleaned, and then disassembled to facilitate the installation of new materials. 3. ** installation process ** - After determining the size of the new material, he drilled a hole and installed it gently. Then, he adjusted the reaction kettle to ensure that the new support and foam plug were stable. ** 3. Cleaning and replacement of paint containers ** 1. ** Clean paint container ** - Clean up the old paint container, use professional equipment to heat and spray it with high pressure to ensure that it is thoroughly cleaned. 2. ** Change paint container ** - A new paint container was installed, and the corresponding clamp was used to fix the container to ensure safety and reliability. ** IV. Replacing the valve and sensor ** 1. ** Replacing the valve ** - First of all, determine which valve needs to be replaced, then use professional equipment to disassemble it, and choose a suitable position for the new valve to install. 2. ** Replacing the sensor ** - Clean the original sensor, then remove it and mark it according to the location where the new sensor is to be installed. For the modification of the reactor involving the key supervision of dangerous chemical processes (such as the modification of the internal heat-conducting oil-injected electric heating reactor without cooling measures): 1. ** For the atmospheric pressure reaction process using heat medium heating ** - The reaction kettle should be equipped with automatic control valve for feed and heat medium, and the reaction temperature can be adjusted by changing the feed flow or heat medium flow. - The reaction kettle shall be equipped with a high reaction temperature alarm and interlocked to cut off the feed or the heat medium. The parallel lock shall be used to open the emergency cooling system (including the cooling medium) and emergency discharge facilities. 2. ** For the pressure reaction process using heat medium heating ** - The reaction kettle should be equipped with an automatic feed or heat medium flow control valve, which can adjust the reaction temperature and pressure by changing the feed flow or heat medium flow. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In industrial production, the reaction kettle electric heating heat-conducting oil furnace had many advantages. For example, its heating system was a closed circulation system, which could quickly heat up and cool down the reaction kettle. It could be customized to a very small volume and was easy to install. It was suitable for medical research occasions. It could realize special control methods such as cascaded control to stabilize the temperature. It could also realize automatic control through remote communication or programming with a PC to provide safety for production. It also played a positive role in reducing the probability of defective products and providing complex temperature control process design solutions. Its power consumption mainly depends on the heating part and the circulating pump, and the power consumption can be reduced through measures such as pipe insulation. In the relevant application scenarios of Zhoushan, the electric heating oil furnace of the reactor could also play a similar role. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The design of the reactor steam pipe signboard had to be done properly. First of all, the words 'steam pipe' had to be written clearly on the signboard so that people could know what kind of pipe it was at a glance. Then, the flow of the pipe had to be clearly marked with an arrow to see if it was going into or out of the reactor. The pressure range had to be written down, for example, low pressure, medium pressure, or high pressure steam pipe. The temperature range could not be reduced either. After all, the temperature of the steam was very important. Also, the number of the pipeline had to be included so that it could be quickly located during management and maintenance. The material could also be written down, be it stainless steel or some other material. There were also safety warning signs, such as high temperature danger, so that people would know to be careful when they saw it. With such a signboard, all kinds of information about the steam pipe of the reactor could be seen at a glance. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
According to the reference materials, the retail price of chemical reaction equipment in Tianshui, Gansu Province was as follows: the price of 2000L porcelain reaction pressure tank was 10,000 yuan; the price of stainless steel stirring tank and stainless steel reaction kettle was 6657.00 yuan; the price of high-speed washing liquid vertical stirring machine and high-speed foaming dispersing machine was 4800.0 yuan. The price of a small stainless steel reactor in Guangzhou, Guangdong, was 5,600.00, and the price of a small stainless steel reactor in Wuxi, Jiangsu, was 1,300.00. However, this could be used as a reference to compare the situation in Tianshui. It should be noted that second-hand chemical equipment is generally quoted at 100 - 200 yuan/ton, but this is very different from the retail price of new equipment and is affected by many factors. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The heating forms of the thermal reaction kettle were jacket type and inner coil type. In addition, the common heating method of the reaction kettle was electric heating.(For example, by installing electric heating elements such as resistance wires, silicon carbon rods, and PAC ceramic inside or outside the reactor, the current can be used to generate heat through the resistance to heat the reactor body or heat transfer medium), thermal oil circulation heating, hot water heating, steam heating, etc. However, the document did not indicate whether these heating methods were specifically applicable to the thermal reactor in Hohhot. Generally speaking, the thermal reactor in Hohhot. may also adopt the above heating methods. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Suddenly having nothing to do and not adapting to it could be considered a situation of maladjustment. Maladjustment was mainly manifested as a series of characteristics that were difficult to adapt to changes in the environment and state. For example, when the pace of life suddenly changed, such as from busy to suddenly idle, there might be psychological or behavior discomfort, such as restlessness, emotional instability, etc. It could also be seen as a situation similar to drug withdrawal syndrome (withdrawal reaction). The body had adapted to the previous busy state, and suddenly being idle was like suddenly stopping a drug that the body had adapted to, causing the body to be in a state of discomfort. However, this discomfort was usually temporary. People could gradually adapt by adjusting their mentality and arranging their free time reasonably. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The usage of the explosion-proof temperature controller for the reactor is as follows: 1. ** Check before use ** - After opening the box, the appearance of the control instrument was checked to see if it was damaged or rusted due to transportation and storage problems. He opened the legs to check if the control instrument was level and if the movable parts were flexible. - According to the name of the connection on the back panel of the control instrument, connect the power supply, heater, motor power supply, temperature sensor, speed sensor and ground wire of the control instrument according to the terminal identification. After checking that there is no error, connect the power supply. 2. ** Temperature-adjustment ** - Follow the instructions of the thermometer. For the first use, it is recommended to set the program and directly use the self-tuning method to determine the P, I, and D parameters through the instrument self-tuning. However, the constant temperature time for the first use is relatively long, and the more accurate P, I, and D parameters can only be determined after three settings are completed. After that, if the same parameters were used, there was no need to start the self-tuning function again, and the temperature could be controlled more accurately. 3. ** Speed adjustment (if any)** - The stirring speed of the motor can be adjusted by the up and down keys of the speed governor. The required stirring speed can be achieved by referring to the speed displayed on the stirring speed display. 4. ** Running Operation ** - Carefully check if there are any abnormalities before normal operation. Do not open the back door during operation to prevent electric shock. - The measuring instruments should be regularly aligned to ensure accurate and reliable operation. The working environment of the equipment must meet the safety technical requirements. - For instruments that have been left unused for a long time and instruments that have been working in a humid environment for a long time, the overall insulation resistance should be measured irregularly. The overall resistance should not be less than 10 Mum. 5. ** Equipment stop operation (no mention of special stop operation for explosion-proof temperature controller of reaction kettle, refer to the general requirements for relevant equipment stop)** - First, turn off the heating or cooling system, then turn off the equipment's power supply, and finally deal with the equipment's water source and air source (if any). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Your question is a little strange. You want to ask if PVP and carbomer will react and if they can be used together, right? As far as I know, PVP and carbomer can be used together under certain conditions, but there is generally no chemical reaction between them. These two were often used in cosmetics, medicine, and other fields. For example, in some gel products, they could work together to give the product the right thickness and stability. However, whether it could be used or not depended on where you wanted to use it and what special requirements you had. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
