Also known as experimental reaction kettle, it is a closed container used to dissolve insoluble substances and is used in small-dose synthesis reactions and atomic absorption spectroscopy and plasma emission analyses. Sample pretreatment. Therefore, it is widely used in research in the fields of petrochemical industry, biomedicine, materials science, geochemistry, environmental science, CDC, food science, commodity inspection and other fields. The hydrothermal method means that after the reaction raw materials are evenly dispersed in water, the formed liquid phase is put into a closed container, and then the container is heated to dissolve and recrystallize the less soluble substances at normal temperature and pressure. Special methods of material synthesis and processing. The basic types of reactions for hydrothermal synthesis of nanomaterials mainly include hydrothermal oxidation, hydrothermal reduction, hydrothermal decomposition, hydrothermal precipitation, hydrothermal synthesis, hydrothermal dehydration, and hydrothermal single crystal growth.
Tianjin Yantu para-polystyrene water heating kettle

/> , Pour the reactants into the polytetrafluoroethylene bushing or para-polystyrene bushing, and ensure that the feeding coefficient is less than.
Make sure the gasket under the kettle body is in the correct position (with the convex side facing down), then put in the polytetrafluoroethylene bushing or bushing-aligned polystyrene and the upper gasket, tighten the kettle lid first, and then use the screw to Tighten the cauldron lid until it is tight.
The hydrothermal synthesis reaction kettle is placed in a heater and heated to the required reaction temperature according to the specified heating rate. (Less than the specified safe operating temperature).
After confirming that the intra-abdominal temperature is lower than the boiling point of the reactant and solvent, the kettle lid can be opened for subsequent operations. When the reaction is completed and the temperature is cooled down, the specified cooling rate must be strictly followed to facilitate safety and the service life of the reactor.
After confirming that the internal temperature is lower than the boiling point of the reactant and solvent, first use the screw to loosen the cauldron lid, and then open the cauldron lid.
The hydrothermal synthesis reactor should be cleaned in time after each use to avoid rust.
In high temperature, high pressure and closed environments, the dielectric constant, viscosity, density and surface tension of water will decrease, and the chestnut product and diffusion coefficient will increase. Due to the formation of water vapor, the pressure of the reaction environment increases. , allowing reactions that usually cannot occur under normal temperature and pressure conditions or have a slow reaction rate to be realized. The water used in the reaction can not only serve as a solvent, but also participate in the reaction. Due to changes in the physical properties of water, it can transmit pressure, accelerate osmotic reactions and control the reaction process, thereby realizing the synthesis of materials.
Currently. Hydrothermal methods can be used to achieve controllable synthesis of single-component and multi-component composite nanocrystals. The nanocrystalline grains synthesized by the hydrothermal method have uniform dispersion and size distribution. Depending on the proportion of raw materials added, composite materials with a certain stoichiometric composition can also be synthesized.
, good corrosion resistance, no harmful substances spilled, reducing pollution, safe to use.
It has a polytetrafluoroethylene bushing inside, double-layer care, and is acid and alkali resistant.
Special specifications can be customized according to drawings and samples.
