Rubber cold adhesive shoe inspection

Rubber cold adhesive shoe testing and rubber cold adhesive shoe testing Rubber products refer to the activities of producing various rubber products using natural and synthetic rubber as raw materials, and also include the use of waste rubber to reproduce rubber products. The production of synthetic rubber has greatly exceeded that of natural rubber, with styrene butadiene rubber being the largest producer. The main raw material of rubber products is raw rubber, which grows on tropical and subtropical rubber trees and is collected by manually cutting the bark. Various additives are auxiliary materials added to improve certain properties of rubber products. Mechanical performance testing of rubber testing items: tensile strength, constant elongation strength, rubber ductility, density/specific gravity, hardness, tensile performance, impact performance, tear performance (tear strength test), compression performance (compression permanent deformation), adhesive strength, wear resistance (wear resistance), low-temperature performance, rebound performance, water absorption, rubber content, determination of liquid resistance Mooney viscosity, thermal stability, shear stability, vulcanization curve Mooney scorch time, vulcanization characteristic testing, physical performance testing: apparent density, transmittance, haze, yellow index, whiteness, swelling ratio, water content, acid value, melt index, viscosity, mold shrinkage rate, appearance color, specific gravity, crystallization point, flash point, refractive index, thermal stability epoxy value, thermal decomposition temperature, kinematic viscosity, solidification point, acid value, ash content, moisture content, heating reduction, saponification value Ester content, liquid resistance, lubricating oil, gasoline, engine oil, acid and alkali, organic solvent, water resistance, combustion performance, fire resistance, flame retardancy, vertical combustion, alcohol burner, combustion tunnel, propane combustion, smoke density, combustion rate, effective combustion heat value, total smoke release, applicability, thermal conductivity, corrosion resistance, low temperature resistance, hydraulic resistance, insulation performance, moisture permeability, food and drug safety and health performance, electrical performance, electrical resistance, dielectric strength testing, dielectric constant Dielectric loss angle tangent measurement, arc resistance measurement, volume resistance test, volume resistivity test, breakdown voltage, dielectric strength, dielectric loss, dielectric constant aging, electrostatic performance aging test: (wet) thermal aging (hot air aging performance), (resistance) ozone aging, ultraviolet lamp aging, salt fog aging, xenon lamp aging, carbon arc lamp aging, halogen lamp aging, weather aging performance, artificial climate aging test, high-temperature aging test Low temperature aging test, high and low temperature alternating aging test, liquid medium aging test, resistance to liquid medium aging, natural climate exposure test, material storage life calculation, salt spray test, damp heat test, sulfur dioxide ozone test, thermal oxygen aging test, user specific condition aging test, low temperature embrittlement temperature.
