How to avoid metal ion pollution in MS enamel reactor

Metal ion pollution mainly comes from direct contact between equipment materials and materials.The defense system of MS enamel reactor fundamentally solves this problem from the contact surface.
1.Fundamental Protection:Physical and Chemical Barrier of Glass Lining
The core of MS enamel glass equipment lies in the silicate glass lining formed on the surface of its metal body through high-temperature sintering,with uniform thickness and dense structure.This layer of inert glass enamel completely isolates the reaction material from the carbon steel or stainless steel substrate.
Chemical inertness:Glass lining has excellent corrosion resistance to most inorganic acids,organic acids,organic solvents,and weak bases,which largely avoids the risk of introducing metal ions due to equipment corrosion.
Smooth and dense surface:High quality enamel has a mirror like surface with low porosity,which not only prevents material adhesion but also effectively eliminates pitting and penetration corrosion,cutting off the path of metal ion leaching from the root.
2.Systematic design:the concept of"zero metal"contact in details
A high-quality MS enamel reactor,with its protective concept running through every detail:
Compatibility of mixing system:The mixing blade is usually wrapped in enamel glass to ensure consistent corrosion resistance with the main body.For special working conditions,metal stirrers such as Hastelloy and stainless steel can be selected,but they will be sealed with mechanical sealing components to ensure complete isolation between the metal part and the reaction medium,achieving pollution-free stirring.
The pure extension of interfaces and accessories:All parts in contact with materials,such as mirrors,manholes,discharge valves,thermometer sleeves,etc.,are coated or made of fully inert materials such as enamel glass,PTFE,PFA,etc.,to ensure the purity of the entire flow path system.
3.Operation and maintenance:a key link in proactive defense
Equipment is the foundation,and proper use and maintenance are the lifeline to maintain its long-term defense.Thermal shock is the number one enemy of enamel lining.Rapid temperature changes can cause internal stress between glass glaze and metal substrate due to differences in expansion coefficients,which may lead to the formation of subtle cracks or ceramic explosions over time.Once the porcelain layer is damaged,the internal metal substrate will be exposed to a corrosive environment,and pollution will quietly come.
Therefore,avoiding metal ion pollution is also a systematic project that requires users to:
Strictly adhere to the heating and cooling rate:usually require≤5°C/min to avoid severe impact of refrigerant or heat medium on the tank.
Standardized feeding operation:It is strictly prohibited to directly feed block shaped or sharp solid materials into empty tanks.It is recommended to add them when there is a certain liquid buffer layer at the bottom of the tank to prevent mechanical damage to the ceramic surface caused by hard objects.
Establish a regular inspection system:regularly enter the tank or pass through the sight glass,use a high-frequency electric spark detector to detect and handle small defects in a timely manner,and nip the risk of pollution in the bud.
4.Technological evolution:the strengthening method of modern MS enamel glass
With the advancement of technology,modern MS enamel glass technology is also constantly evolving.For example,using double-layer enamel or even three-layer enamel technology,layer by layer stacking,makes the porcelain layer thicker,more uniform,and has better toughness,significantly improving impact resistance and thermal shock resistance.In addition,the application of laser welding technology in equipment manufacturing reduces defects in the welding area,ensures the integrity and reliability of the porcelain layer coverage,and lays the foundation for high-purity cleanliness from the manufacturing end.
Choosing an MS enamel reactor is not only about choosing a corrosion-resistant container,but also about choosing a complete set of solutions dedicated to"zero pollution".It constructs a multi-dimensional three-dimensional protective network from the essence of materials,design details,manufacturing processes to your standardized operations,isolating metal ions from your sensitive reactions.If you are troubled by metal ion pollution issues or planning a new project with strict requirements for product purity,we sincerely invite you to have in-depth discussions with our technical experts.
