Introduction to glass lined reactor

In the production workshops of chemical,pharmaceutical,food and other industries,glass lined reactor vessels have become the"core equipment"for handling highly corrosive media with their unique"glass lined reactor+metal shell"structure.It can withstand harsh working conditions of high temperature and high pressure,while avoiding pollution caused by contact between materials and metals,making it an industrial container that combines rigidity and flexibility.

The enamel glass lined reactor is composed of a metal substrate and enamel glass layer,supplemented by components such as a stirrer,heat transfer jacket,and sealing device,forming a composite structure of"internal anti-corrosion and external pressure bearing":

1.Glass lined layer:using silicon dioxide as the main material,adding borax,fluoride and other fluxing agents,after high-temperature firing at 900℃,a dense glassy coating is formed,with a surface hardness of HRC55-60 and better acid and alkali corrosion resistance than ordinary stainless steel.
2.Metal matrix:Provides structural strength,withstands reaction pressure and mechanical loads,while optimizing heat transfer efficiency through thermal conductivity.
3.Transition layer:A 0.1-0.3mm alloy transition layer is formed at the interface between metal and enamel glass to solve the problem of porcelain detachment caused by the difference in thermal expansion coefficients between the two.
Working principle of enamel glass lined reactor
1.Chemical inertness:The glass lined reactor of the enamel reaction vessel is stable and does not react with most acids,bases,and salts.
2.Physical barrier:A dense and pore free surface prevents the penetration of media and prevents the corrosion of the metal substrate.
3.Stress dispersion:The metal substrate of the enamel reaction vessel absorbs external impacts to prevent cracking of the enamel layer.
The enamel glass reactor,with its core advantages of corrosion resistance,easy cleaning,and precise temperature control,has become an indispensable key equipment in industries such as chemical,pharmaceutical,and food.With the integration of intelligent monitoring technology and green manufacturing concepts,the new generation of glass lined reactor vessels is upgrading from"functional containers"to"intelligent reaction platforms",providing solid support for the high-quality development of the industry.
