Many people doubt, stall on the market sell insulation rubber mat place so much, how to test and measure the insulation rubber kraal pad is good or bad? The Thai rubber to tell you, what good insulating rubber kraal mat? Rubber insulation rubber elasticity is to choose the kraal mat of a standard, good flexibility to insulation rubber kraal mat on floor, and other process is not easy to fracture, and has good stretching resistance and extendability. So good insulating rubber kraal pad should have very good elasticity. Insulating rubber kraal pad inspection standards: ( In the case of 8 mm insulation rubber kraal pad) 。 1. Appearance: 1) Spot mark depth and height no more than 2 rubber sheet thickness tolerance) Bubbles per square meter, area of less than 1 cm of the bubble is not more than five, the distance between any two bubbles not less than 40 mm. 3) Impurities depth and length of no more than 1/6 of the thickness of rubber sheet. 4) Edge is not neat or shape of the surface width is not more than 10 mm, length less than 1/10 of the rubber plate length. 5) There is no crack. 2. Hardness ( Shao Er A) : 55 - 70. 3. Insulating rubber kraal cushion tensile strength and elongation at failure: 1) Tensile strength ( Mpa) ≥5. 0. 2) Elongation at failure 250% or higher. 4. Stretch ( 150%) Permanent deformation of 25% or less. 5. The hot air aging ( 70℃*72h) : tensile strength reduced rate of 30% or less. 6. Water imbibition 1 or less. 5%. Based detection surface insulation rubber sheet flecked the depth of the concave and convex parts or height shall not exceed the rubber sheet thickness tolerance, bubbles per square metre, the area is not in 1 cm2 bubble is not more than 5, the distance between any two bubbles is not less than 40 mm, the length and depth of impurity does not exceed the plastic board thickness is not less than 40 mm, not neat or spongy edges of a rubber sheet width does not exceed 10 mm, length less than 1/10 of the rubber plate length, and there is no rift. General unit after buying insulating rubber kraal pad can not timely, or unused, so, it is important to note that the deposit environment. Insulating rubber kraal pad should be stored in dry and ventilated environment, away from the heat source, more than 20 cm off the ground and wall. Avoid by acid and alkali and oil pollution, do not open to prevent avoid direct sunlight. The aluminum alloy doors and Windows of chongqing SEO related: shenyang tai rubber kraal mat zha production?
