Corrosion-resistant diaphragm pump

Corrosion-resistant diaphragm pumps use compressed air to drive the reciprocating motion of the diaphragm for liquid transfer, with the diaphragm isolating the medium from the pump body. They are used to convey corrosive liquids such as acids, alkalis, and solvents, and are employed for transferring or circulating fluids in chemical processing, electroplating, and wastewater treatment.
Selection
Select the diaphragm material based on the corrosiveness of the conveyed medium, such as PTFE for strong acids. Determine the pump body size according to flow requirements, and choose the inlet and outlet diameters considering fluid viscosity. The working pressure must match the air source pressure, and environmental requirements determine the explosion-proof rating.

Salt spray test chamber for testing the corrosion resistance of plastic coatings.
The salt spray test chamber accelerates the testing of the corrosion resistance of plastic surface coatings by simulating a salt spray environment containing chloride ions. The test is conducted in accordance with international standards such as ASTM B117 or ISO 9227, and the process includes sample preparation, salt spray exposure, and result evaluation.
Coulometric thickness gauge measures the sealing quality of anodic oxide films.
This article introduces a method for assessing the sealing quality of anodic oxide films using a coulometric thickness tester. The sealing quality affects the corrosion resistance and wear resistance of the oxide film. Based on electrochemical principles, the coulometric thickness tester evaluates the sealing effectiveness by measuring the electric charge required to dissolve the oxide film, providing objective and repeatable results.
Salt spray test chamber detects the corrosion resistance of coatings.
The salt spray test chamber accelerates the testing of coating corrosion resistance by simulating a salty and humid environment. It uses atomized sodium chloride solution to form salt spray, which settles inside the constant temperature chamber, and conducts tests under neutral or acidic conditions in accordance with standards.
Applicable Scenarios for Neutral Salt Spray and Copper-Accelerated Acetic Acid Salt Spray Tests
Neutral salt spray testing and copper-accelerated acetic acid salt spray testing are both accelerated methods used to evaluate the corrosion resistance of materials, simulating saline environments to predict long-term performance. The neutral salt spray test uses a neutral sodium chloride solution, which causes relatively mild corrosion and is suitable for general metals and coatings, such as automotive parts.

Selection of Ceramic vs. Cast Aluminum Heating Surfaces for Laboratory Hot Plates
When selecting a laboratory heating plate, ceramic and cast aluminum are two common materials. Ceramic offers high-temperature resistance, corrosion resistance, and uniform heating, but it heats up slowly and is relatively brittle. Cast aluminum heats up quickly and is sturdy and durable, but it has weaker corrosion resistance and a lower maximum temperature.
