Interpretation of the RCA Tape Wear Tester Working Principle


Tape wear test machine with mobile phone, PDA, MP3, CD machine, laptop and a variety of surface coating test wear test, load 275g, 175g.55g. Scrolling the paper or tape without oil and the friction of the sample after a certain number Of revolutions to determine the effect of its wear. Wear refers to an object on the surface of another object relative movement, so that the latter work on the surface of the material gradual depleted. Strictly speaking, tape wear test refers to the abrasive exhaust caused By the loss. Filled with fine pattern of the sample used. Applicable to mobile phones, PDA, and so on. Applicable to mobile phones, PDA, MP3, CD players, laptop computers and a variety of materials on the surface of ink and printing wear test

The tape abrasion test machine having a number of times to reach the stop function and having breaks down function, which can reduce product testing abrasion tests error, better test for a customer to save paper.Instructions:1, scroll uncoated paper or tape friction with the sample oil after the determination of the effect of the wear certain number of revolutions;2, for the softer material load of 55g or 175g mitigate;3 with with a magnifying glass to view;4, the counter: Digital counter (Led display, 0-9999 can set the number of revolutions);

Paper tape wear test machine works:① with a special tape as a friction medium, with a fixed load on the friction head, the friction head through a fixed diameter roller and constant speed motor drive rotating paper, the force applied to the sample surface, until you see the surface Substrate or To achieve a certain degree of wear and tear, through the counter shows the number of motor rotation to evaluate the sample anti-friction function.② for the more soft material to reduce the weight of 55g or 175g, two species of sample fixation options, suitable for flat or 3D samples.GD-7-IBB-CC type digital counter (LCD display, 0 ~ 999,999) can be set to the required number of revolutions.④ load 55g, 175g, 275g (Note: scale test load of 275g, the lever is not added weight loss weight), with weight reduction weight two, the test load can be reduced to 175g or 55g.

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...
