Classification of Sunlight Color Fastness Test Equipment



Sunlight color fastness meter also known as xenon arc lamp weathering test chamber, sun color fastness tester is a xenon lamp as a light source, and simulated rainfall, temperature and humidity, condensation and other climate environment, light aging test chamber, available In the simulated light aging test can also be used for light color fastness test, the current points are water-cooled, air-cooled and box, desktop three structural and aging methods, the following are three structural features:
Water-cooled sun color fastness structure:Water-cooled refers to the use of water-cooled xenon lamp as a light source, the box structure as a standard vertical, due to the lamp cooling cycle, the top of the box placed a circulating water tower device. The inside of the test chamber is placed vertically with the water-cooled lamp tube. The lamp tube is surrounded by a clip, and the fixture and the bottom turntable are formed together to form a sample rack. The whole is a cylindrical structure. Before the test, the sample material was clamped on the sample rack so that the light radiated from the lamp was irradiated onto the sample surface. At the beginning of the test, the turntable starts to rotate and the radiation source is aged.
Air-cooled sun color fastness structure:As the air-cooled xenon lamp and water-cooled xenon lamp power difference is large, water-cooled test box with three air-cooled lamp to replace the water-cooled lamp, and can save the water tower device, simplify the equipment structure. Three tubes are placed horizontally at the top of the liner and vertically illuminated at the bottom of the sample surface. There is no special restriction on the state of the sample material and is satisfied with a variety of material product tests.
Box-type sun color fastness meter:Gu Mingsi, box-style three-dimensional box-type xenon lamp aging test box, his design aesthetic and easy to operate, the internal volume of large space and the test environment is open, easy to observe and test is known, is currently the most widely used machine Type, the current Atlas xenon lamp weathering test machine sales in China, the most types of CI3000 and Ci4000 and CI5000 models are  basically box-type majority.
Desktop sun color fastness meter structure:Desktop also known as the desktop, convenient, simple, is a can be placed on the table for aging test equipment, it can be said that the air-cooled mini version. Desktop with a cold air or cold water tube in the top of the liner, under the irradiation, light aging. Because of its simple structure, easy to use, currently in many scientific research units and tertiary institutions use a very wide
Currently on the sun color fastness of the many brands, the use of a larger Atlas  sun color fastness tester and Italy cofomegra sun color fastness and other brands, there are some domestic to do more successful cases.

Classfication Of The Textile Testing

Textile testing is the term for a whole series of tests that examine the physical, mechanical and chemical properties of textiles. These tests are sometimes done before a textile goes into widespread use, or they're done on textiles arriving from other countries for sale in US markets. Countries like the United States have established standards for what should and should not be in textile products. Tests can show whether companies making textiles are in compliance or not. Many textile tests have many types. Some of them are physical tests, in which a sample of textile material is examined closely for feel and appearance. Such tests are done on individual fibers or strands of material and on yarns, threads made of several fibers twisted together. Textiles are subjected to light and other elements to see how they react. Some of these tests are done in a weather-ometer, a machine that tests for weathering and lightfastness of textiles. It's basically an enclosed box. Textiles...

Synthetic Blood Penetration Tester for Medical Face Mask

  Features of Synthetic Blood Penetration Tester: 1. Mask fixture is metal human head mold, which can fully simulate the actual use state of the mask. 2. Metal human head mold can be rotated at a certain angle, which is convenient for sample clamping. 3. Specially designed injection control device, a certain volume of synthetic blood can be sprayed in the controlled time. 4. Instrument uses a gas source that can provide (700±25) kPa stable air pressure. 5. It can simulate the liquid injection velocity corresponding to the human blood pressure 10.6 kPa、16.0kPa 、21.3kPa (i.e .80 mmHg、120mmHg、160mmHg) for the test. 6. A fixed target plate is provided to block the high pressure edge part of the ejected liquid flow, only the steady flow part is sprayed on the area sample, which increases the accuracy and repeatability of the test. 7. This blood penetration testing equipment uses imported special aluminum wire drawing panel, equipped with metal keys, sensitive operation, not easy to dama...

Determination of air permeability of a fabric-air permeability tester

Fabric air permeability is a measure to what extent it gives air passing through the fabric. Air permeability, a given area in the vertical direction of the air flow rate, a given time period, is measured by the fabric test area inside the pressure difference of the fabric. Basically, it depends on weight, thickness and porosity of fabric. The porosity of fabric is the demonstration of the air gap as a percentage within fabric. It has been important for especially the tent fabric, parachute fabric, raincoat fabric and garment, the fabric used in air bags, industrial filters and sail cloth. Moreover, when thermal properties of clothing and body interaction are taken into consideration, there has been the effect of air permeability. there is an instrument which is designed to test the air permeability of fabric on the market .it is air permeability tester . Air permeability is an important feature of fabrics (Sundaramoorthy et al., 2011) and is one of the main factors affecting the t...
