A Guide To Glove Cutting Resistance Testing Machine

      Cut-resistant gloves are designed to protect hands from direct contact with sharp edges such as glass, metal, ceramics and other materials. Cut resistance is a function of a glove’s material composition and thickness.You can increase the level of cut protection by increasing material weight (i.e., ounces per square yard); by using high-performance materials such as Dyneema®, Kevlar®, and metal mesh; or by using composite yarns made with varying combinations of stainless steel, fiberglass, synthetic and high-performance yarns.      For a glove manufacturer ,you need refer to a test machine to know how your gloves perform on the anti-cut performance . Anti Cut Glove Testing Machine is use to determine the protective capability of the safety glove against cutting.But,it is not available for safety glove made by hard material.A driving rotation found blade under a specified load cuts the glove held by the fixture of tester to and fro. After test ,compare it with its original status

A Article For Operating Horizontal Vertical Flame Tester

      Horizontal vertical flame tester is to simulate the electrical environment around the electrical environment of the early situation,to simulate the technology to assess the risk of fire, and to make sure the product around the fire that will not cause burning spread. Test equipment for electrical and electronic household appliances parts, parts and components, such as: household appliances, insulation shell, switch panels, printed circuit boards and insulation materials.          Horizontal and vertical flame chamber is designed for combustible performance testing of equipment and appliance parts. Many of the test indicators for end using such as flammability, combustion rate, flame spread, combustion strength and flame retardancy of the product are Was detected. High degree of automation, accurate test data, is our high demand for users to launch the latest tester. Horizontal Vertical Combustion Tester Experimental Operation Method: 1, with a gas pipe connected to t

DIN Abrader For Rubber Testing

      Rubber is polymeric material endowed with the properties of flexibility and extensibility: with the application of force, the molecules straighten out in the direction in which they are being pulled; on release from being extended, they spontaneously recover their normal, random arrangements. Rubbers include natural rubber, a naturally occurring substance obtained from the exudations of certain tropical plants, and synthetic rubbers, artificially derived from petrochemical products. Among the most important synthetics are styrene-butadiene, polybutadiene, and polyisoprene (commonly classified as the "general purpose"), as well as ethylene-propylene rubber (often referred to as "specialty rubber").        For rubber,“abrasion” covers all mechanisms, whereas the word “abrasion” for other materials refers in particular to scoring by hard, sharp particles. In the absence of transient effects such as clogging of the abrasive or evolution of an abrasion patter
