Do Testing With A Zipper Reciprocating Pull tester

Textile test machine manufacturer:       Zipper Reciprocating Fatigue Test Equipment is used to test zipper in horizontal and vertical forces, can withstand the required number of pulling back and forth. Stop the machine in the test after pulling the zipper pull head to the required number of pull 30rpm constant speed, and then view the zippers damaged cases.                                             Test preparation : Adjustment knob until the tab located at the highest position of the clamping device B, and this means added fixed pad The zipper pull tab secured to the pull-tab clamp B. First zipper trailing end (lower end stop) roughly fixed to the upper clip within the first A point (in this case the first clip and zipper center vertical centerline). The zipper front end (top dead end) fixed to the two longitudinal clip head at point E(E-point clip longitudinal head when holding the specimen cannot be clamped sprocket, two specimens shall live clip head in the same posit

What Is Aging Test Chamber For Weather Resistance Test?

            Textile test machine manufacturer : It is known for textile manufacturers that  UV aging test chamber can simulate and strengthen the environmental factors in the natural climate that are affected by light, heat, humidity, and rainfall as the main aging. It can simulate the accelerated test under long term exposure to obtain the results of the weather resistance of the material. UV aging tester is to simulate lighting; it specially simulates products long-term placement in the outdoors. It just takes a few days or weeks to simulate the damage resulting by ultraviolet in sunlight, which takes a few months or years in outdoors.To check whether the products have fading phenomenon, chaseleon phenomenon, brightness decreased, powder phenomenon, cracking phenomenon, fuzzy phenomenon, embrittlement phenomenon, strength loss and oxidation phenomenon; it can also reproduce the destruction of rain and dew at the same time. UV aging test chamber does the test by placing the

Dry Cleaning & Washing Cylinder For Testing

     Dry cleaning is any cleaning process for clothing and textiles using a chemical solvent other than water. It is used to clean fabrics that degrade in water, and delicate fabrics that cannot withstand the rough and tumble of a washing machine and clothes dryer. It can eliminate labor-intensive hand washing. Dry Cleaning & Washing Cylinder used to determine the colorfastness to dry cleaning and chlorinated pool water, also it can suitable for preparing the specimen before flammability testing.Dry cleaning & washing cylinder included bracket, stainless steel dry cleaning cylinder and electric control case. Rotation speed of the cylinder could be adjusted and testing time could be set. Operation: Clean the dry cleaning cylinder Prepare the hardness concentrates according to the relevant standards. 51 ml of the hardness concentrate was diluted to 5100 ml with distilled or deionized water. If necessary, adjust the pH of the solution to 7.0 with sodium carbonate or ac

Scratch Testing With Multi-Finger Scratch / Mar Tester

      Multi-Finger Scratch / Mar Tester  is used to measure the relative resistance or susceptibility of a material surface to scratching, marring, gouging, scraping, engraving and other similar physical damage not classified as ordinary wear. Based on the apparatus described in popular automotive specifications, the instrument is commonly referred to as a five-finger (five-arm) scratch & mar tester and most often used to evaluate plastics. This  Multi-Finger Scratch / Mar Test instrument  is used to evaluate the scratch and mar resistance of resilient materials. A variable speed, pneumatically driven sledge is moved below five independent, weighted scratch "fingers" that are equipped with interchangeable scratch tips. Includes: spline shaft 'finger' assembly (5); scratch tip with 1.0mm diameter hemisphere (set of 5); mar tip with 7.0mm diameter hemisphere (set of 5); weight set (consisting of 2N; 3N; 4.5N; 5N; 6N; 7N; 10N; 15N; and 20N); and specimen clamp.

Scrub Abrasion and Washability Tester For Testing

     Abrasion scrub/ washability Test to perform an abrasion and washability  test on coated panels to define the resistance of paint, varnish or related products to scratching, wearing and colour loss due to wet or dry abrasion. Simulating everyday wear from cleaning actions or general use.         The test is either used as a “pass / fail” test by testing to a specified number of strokes or defining the minimum number of strokes at which a coating fails by checking at regular intervals.     Scrub Abrasion and Washability Tester is used to evaluate the wash/scrub resistance and cleanability of coatings (especially emulsion paints and "wall paints"). There are wide-range parameter settings so that the individual tests can be specified as required (e.g. for testing cleaning solutions, etc.).     The basic unit of  Scrub Abrasion and Washability Test machine   can be levelled and is equipped with a cover plate for supporting the steel tub. It also has an integ

Scratch Testing With Reciprocating Abrasion Tester

    Textile test instruments manufacturer: Reciprocating abrasion tester used by way of rotary grinding, using different kinds of friction wheel rotational friction on the sample to detect wear performance for leather and plastic materials, make scientific evaluation of the wear resistance on the product.                                  Reciprocating abrasion tester   Description: Test products are fixed at the level of the table, in the abrasives and load with the movement of the   provisions under the level of water for the station being worn; The use of the principle of leverage, the other end of the arm with the test weight to maintain    balance test arm to ensure the reliability and accuracy of the sample surface load test results. Abrasives and load frame height is adjustable to be suit for different height of the sample tested. According to the different requirements of customers, the use of different media to test different  products friction abrasion resistance.
