Heat Resistance and Permeability Tests

Heat Resistance and Permeability Tests

Glass fiber fabrics are used more than hand in heat resistance. Glass fiber fabrics are a unique industrial textile material that is used in many different ways. These fabrics show excellent resistance to heat and abrasion. It is a superior material that is widely used especially in areas exposed to high temperatures and where minimal weight is required. It also provides excellent results for electrical insulation.

Glass fiber is generally produced from materials used in glass production such as silica, aluminum oxide and soda, and is the most widely used among fiber-reinforced composite materials. Glass fiber is produced by pushing and solidifying the glass melted in a special furnace specially designed for this purpose through the fine holes like bottom sieve. After cooling, these fine fibers are wound onto reels and turned into ropes. The temperature transmission coefficients of the ropes thus obtained are very low. It is therefore used for insulation purposes or as reinforcing agents in woven products and in some plastic products.

Glass fibers have higher strength properties than carbon fibers. Fiber fabrics are therefore generally produced from glass fiber fibers. Different types of glass fibers are obtained by adding different chemicals during production and applying some special processes.

Specially designed high temperature resistant paints are used for various metal surfaces exposed to high temperatures up to 600-700 grades. Such paints are generally used on all interior and exterior surfaces exposed to high temperatures, such as steam boilers, thermal power plant chimneys, exhaust pipes and fireplaces. In addition, heat-resistant paint is used in industrial plants, petrochemical plants, steel mills, refineries, chemical processing plants such as sugar, fertilizer and cement, and at points where the steel temperature rises to 600.

Heat-resistant paints are generally topcoats and have high physical resistance and heat resistance. Some types provide resistance up to 800 degrees. In order to achieve the expected success of such paints, the metal surfaces to be applied must be cleaned of all kinds of moisture, chemical dust, rust and metal residues. Paints are decorative materials that form a film layer when dried and have protective properties. They form a film layer when drying on the material surface. It is provided that this layer gains protective properties against various external effects with the chemicals placed in the paint production. Therefore, heat resistance levels may vary according to the type of paint.

In laboratories that provide inspection, test and analysis services, glass wool, dyes and other materials that provide heat resistance to industrial materials are tested and analyzed. While these laboratories comply with the requirements of domestic and foreign legal regulations, they also take into consideration the standards developed by domestic and foreign organizations.

In addition, these laboratories perform these tests based on the authorization they have received from domestic and foreign accreditation institutions. The accreditation system refers to a system to ensure that organizations, services or activities meet certain competency criteria. This system is based on standards that are defined and continuously updated based on internationally accepted values.

Laboratories are generally organizations that provide testing and calibration services and conduct conformity assessment studies. The conformity of the products to the specified criteria, standards, buyer demands and consumer preferences and expectations are documented at the end of the tests and analyzes in these laboratories. In our country, which is in the process of joining the European Union, laboratory services are gaining increasing importance. This issue is extremely important in commercial activities with foreign countries. In the European Union countries, the products to be introduced to the market are in principle free circulation. In order to remove the barriers to the free movement of products, the European Union has introduced the latest New Approach Directives. In this application, the intervention of the relevant official institutions is limited and the enterprises are given a wide choice in fulfilling their obligations. In this regard, accredited laboratories also have great responsibility. Conformity assessment studies of products to be released to free circulation include measurement, inspection, test and analysis studies to be performed in these laboratories.

Our company carries out heat resistance tests of all kinds of industrial materials such as glass, metal or paint in accordance with local and foreign legal regulations and related standards.
