Carbomer is an acrylic resin obtained by cross-linking pentaerythritol with acrylic acid. It is a very important rheological regulator. After neutralization, carbomer is an excellent gel matrix, which has important applications such as thickening suspension. According to the dry product calculation, including carboxylic acid group (-cooh) should be 56.0 % ~ 68.0%.
Common carbopol series include: Carbopol 940, 941, 934, 1342, 980, ETD 2020, AQUA sf-1, Ultrez 21, Ultrez 20, etc.

1. Before the stainless steel reaction kettle is started, check whether the inside of the kettle, the agitator, the rotating part, the auxiliary equipment, the indicating instrument, the safety valve, the pipeline and the valve meet the safety requirements. 2. Check whether water, electricity and gas meet safety requirements.
2. In the stainless steel reaction kettle, the mixer of the reaction kettle should be opened before feeding. If there is no noise and normal, the material should be added to the reaction kettle. The amount of feed should not exceed the process requirements.
2. Before opening the steam valve, first open the air valve and then open the air inlet valve. Open the steam valve should be slow, so that it is preheated to the jacket, and gradually increase the pressure inside the jacket is not allowed to exceed the specified value.
3. The steam valve and the cooling valve cannot be started at the same time, and the steam pipe is not allowed to hammer and collide when it is over-gas.
4. When opening the cooling water valve, first open the water valve and then open the water valve. The cooling water pressure must not be lower than 0.1 MPa, nor higher than 0.2 MPa.
5, water ring vacuum pump, you must first open the pump after the water supply, stop the pump, stop the pump and then stop the water, and should exclude water in the pump.
6. Check the operation of the reactor at any time and find that the abnormality should be stopped for maintenance.
7. When cleaning the titanium epoxy (enamel) reactor, do not use alkaline water to brush the reactor, taking care not to damage the enamel.
3. After the stainless steel reaction kettle is stopped, stop stirring, cut off the power supply, and close various valves.
2. When shovel the pot, the power of the mixer must be cut off, the warning sign should be hoisted, and the guardian should be set up.
3. The stainless steel reaction kettle must be subjected to periodic technical inspection according to the requirements of the pressure vessel. If the inspection is unqualified, it shall not be driven.
