Taber Abrasion Tester test operation method How does the Taber type abrasion tester perform the friction test?   From the outside, it is not very obvious, but the equipment is actually used to test the abrasion resistance of leather and plastic, fabric, floor tiles, and plywood by rotating and rubbing different types of friction wheels on the specimen (wheel numbers include H18, H22, CS10, CS17, CS32, CS33).   It can be seen that the Taber type abrasion tester relies mainly on rotary grinding, so that it is used to test the abrasion resistance of leather and plastic materials by using different types of friction wheels to rotate on the sample through the test disc. This requires us to choose the set of weights applicable to the standard. The abrasion index has a formula which is: weight of abrasion loss / number of test rotations * 1000 The results of the test are used to identify the properties of the test material and to check the weight loss on the outer surface of the samp...

Did you know? Crash test dummies that are more expensive than cars At the end of each crash test, professional engineers will give the crash vehicle a score. The reference basis for scoring, in addition to the assessment of the damage to the vehicle, but also to the car "personnel" injury assessment, at this point, that is the role of the crash test dummies. Crash test crash test dummies are based on a large number of cadaver test research (this is also the crash test crash test dummies research and development cycle is long, one of the reasons for the high price), crash test dummies are mostly made of metal and plastic, the chest cavity is made of steel, the shoulder blade is made of aluminum, the pelvis is made of plastic. The cost is up to about $ 40,000, if coupled with the sensor supporting equipment, the cost is up to $ 60,000 to $ 70,000. Why crash test dummies are widely used in automotive crash testing? In the early car crash test, the staff will personally participa...

Textile Ici Pilling Tester Principle and 4 Points to Note Testing principle.   When testing, the barrel-shaped specimen is set on the rotating cylinder and the nail hammer suspended by a chain is placed on the surface of the specimen. When the cylinder rotates at a constant speed, the nail hammer will randomly flip and jump on the surface of the specimen, and hook the specimen, the surface of the specimen produces hooks. After a specified number of revolutions, the specimen is rated against the standard sample for the degree of hooking. Two stations, four stations are optional. Operation instruction.   The 105mm × 105mm samples are put into the test chamber, the rotation of the impeller, the cork-lined wall of the shelf box continues to randomly rub, the timer will be set to the specified time, the sound holds tight after reaching the set time, prompting the end of the test. Test will be injected into the test chamber during the test compressed air to enhance the flip, air pre...

Explanation On Why Sweating Fabric Manikin Is Important Sweating Fabric Manikin  principle analysis: Human body sweating can be divided into hidden sweating and visible sweating. When the temperature is low, that is, below 20 ℃, people are in a static state, through breathing, skin pore diffusion, every hour from the body sweat, heat, this sweating people do not feel, so called no sense sweating, called recessive sweating. When the temperature rises above 25℃ to 30℃, the human body emits about 174-348 kcal of heat per hour through radiation and convection without showing sweat, but it is still lower than the heat produced and needed in the body, then the human body has to dissipate heat in the form of evaporation by discharging sweat through sweat glands all over the body. This sweat is in a liquid state, so that people are in a more comfortable state, thus maintaining the important function of energy and health. The unobtrusive sweating that occurs in a day and night is about 500-...

Martindale Abrasion Tester test specimen preparation   1、Selecting of specimens   In order to provide representative specimens, it is necessary to select parts containing different warp and weft yarns, and special attention should be paid to certain specimens with special properties. For example, printed fabrics selected specimens to include the entire pattern, to avoid missing certain friction-sensitive parts; woven fabrics need to maintain a certain distance from the edge of the door width. In addition, the number of specimens selected also affects the accuracy and repeatability of the test. The more the number of specimens tested, the stronger the representation, the higher the accuracy, and conversely, the number is too small, the greater the randomness of the test results, low reliability, the minimum number of specimens selected for 3. 2、Pre-treatment of specimens   As the fabric is sent before the test are packed and wound, in a taut state, in order to better test,...

Here we learn what other factors influence the Ozone Aging Chamber in the rubber ozone aging process: 1. The role of rubber type. (1) Double bond content: the higher the double bond content of the rubber, the stronger its ozone aging resistance; (2) double bond carbon atom substituent properties: electron-absorbing substituents reduce double bond reactivity and ozone reactivity; electron substituents increase electron cloud density and improve double bond reactivity and ozone reactivity. ozone aging resistance of CR, BR and NR is CR>BR>NR. The effect of ozone treatment concentration: the higher the level of ozone quality concentration, the worse the ozone aging resistance of rubber; under the same ozone with concentration, the rubber industry structure proceeds differently, and the ozone aging time characteristics are studied differently. the cracking time of NR is short, but the development speed of cracking growth is slow; the cracking time of SBR, BR and NBR is long, but the c...

10 effective ways to deal with textile pilling Here to teach you the textile pilling 7 effective ways to deal with: 1. Choose the fiber that is not easy to pilling in the process of yarn and fabric production. 2. Pre-treatment and dyeing in the jet dyeing machine with Lubsoft lubricant to prevent rubbing. 3. Use crystalline sodium sulfate instead of common salt when dyeing cotton and polyester/cellulose blends with reactive dyes in jet dyeing machines. 4. Appropriate heat setting is used for polyester/cellulose fiber and polyester/wool blends to set the yarn and overfeed appropriately. 5. Brushing is performed at the same time as shearing to remove surface fibers as well as protruding fibers. 6. Both sides are burnished to remove surface fibers as well as protruding fibers. 7. For polyester and polyester/cellulose blends, partial alkali reduction of the polyester component can reduce the strength of polyester, so small balls can be easily removed.
