Porosity testing

Measurement of catalyst surface area and porosity. Intertek measures catalyst surface area, porosity and other important catalyst measurement factors. We provide world-class expertise in both catalyst surface area analysis and catalyst porosity testing.

Catalyst Surface Area Analysis: Total catalyst surface area is usually . Learn how to find your hair porosity and hair density to help you make better decisions on caring for your curls.

There are two methods you can use to find out how porous your hair is.

If your hair floats, you have low porosity.

If it sinks, you have high porosity. Defect analysis of cast products quite often include evaluation of surface or subsurface defects formed by entrapped gas. Materials Acetone, Sodium Nitrate, Reagent GD. If you have oils or products on your hair, it will alter your . High Voltage Technique: The high voltage, or porosity technique, can be used to test coatings up to 25mm (1”) thick and is ideal for inspecting pipelines and other protective coatings.

Coatings on concrete can also be tested using this method. Thermtronix porosity testing measurement system. ALUMINUM POROSITY MEASUREMENT SYSTEMS. A major use of this test procedure is for determining coating quality. GPI manufactures physical property test instruments for stiffness, flexibility, water absorption, softness, porosity , air-permeability and smoothness.

A leading supplier and manufacturer of different types of porosity testing , porosity testing equipment and much more. Because it is impervious to high temperatures and chemically reactive substances, vitreous enamel makes an excellent anti- corrosion barrier for the boilers and tanks used in the chemical and pharmaceutical industries. Search for pores and defects in linings and coatings made of enamel, lacquer, rubber and bitumen as well as in containers made of GFK and other synthetics. Porosity Test Using High Voltage. The Left Brain responds: Amma, thanks for taking time to comment on our blog.

These porosity tests involve corrosion reactions in which the products delineate defect sites in coatings. Since the chemistry and properties of these products do not resemble those found in natural or service environments, these tests can not be recommended for the prediction of the electrical performance of contacts unless . Methods of test for dense shaped refractory products. Determination of bulk density, apparent porosity and true porosity.

Point defects such as pinholes laid down during deposition and generated during thermal cycling may act as starting points for severe film cracking at high temperature. Tests carried out on evaporated coatings of .
