Beijing Yantu para-polyphenylene hydrothermal kettle
Also known as sample dissolver, hydrothermal synthesis reaction kettle, high-pressure digestion tank, digestion tank, pressure digestion tank, and sealed sample dissolution tank, it is a closed sample dissolution tank used to dissolve insoluble substances The container is used for sample dissolution pretreatment in small-dose synthesis reactions and analysis such as atomic absorption spectroscopy. 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 refers to the material synthesis in which the reaction raw materials are uniformly dispersed in water, the liquid phase formed is put into a sealed container, and then the container is heated to dissolve and recrystallize substances with poor solubility at normal temperatures and pressures. and special methods of 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.
Technical parameters of water heating kettle:

Pour the reactants into the PTFE bushing or para-polystyrene bushing and ensure that the feeding coefficient is less than.
Make sure that the gasket under the kettle body is in the correct position (with the convex side facing down), then put in the polytetrafluoro bushing or bushing to align the polystyrene and the upper gasket. First, tighten the kettle lid, and then use the screw to twist the kettle lid. Tighten until tightened.
The hydrothermal synthesis reaction kettle is placed in a heater and heated up 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 temperature inside the abdomen is lower than the boiling point of the reactant and solvent, first use the screw to loosen the lid of the kettle and then open the lid of the kettle.
The hydrothermal synthesis reaction kettle must be cleaned in time after each use to avoid rust.
, good corrosion resistance, no spillage of harmful substances, reducing pollution and safe to use.
It has a polytetrafluoroethylene bushing with double-layer care and can withstand acid and alkali.
Special specifications can be customized according to drawings and samples.
