Other performance introduction of  hand wheel

Vulcanized natural rubber elastic rubber and its crosslinking density is not too high, the elasticity is high. For example, in the range of 0-100 DEG C, elasticres at 50-85 DEG C, the elastic modulus of steel is only 1/3000, the tensile elongation is up to 1000%, to 350%, after retraction of permanent deformation is only 15%, a higher elasticity of natural rubber, rubber in general after polybutadiene rubber hand wheel.

The strength of natural rubber in the elastic material, natural rubber raw rubber, rubber, vulcanized rubber with higher intensity. The tensile strength of the vulcanized rubber handwheel is called Green strength. The Green strength of the natural rubber wheel can reach 1.4 to 2.5Mpa, and the proper Green strength is necessary for the processing of the rubber handwheel. Natural rubber hand wheel tear strength is higher, up to 98kN/m, and its good wear resistance. The reason for the high mechanical strength of the natural rubber hand wheel is that it is self reinforcing rubber handwheel. When stretched, the macromolecular chains are oriented in the direction of stress and form crystals.

Natural rubber hand wheel electric performance, natural rubber hand wheel is non-polar material, is a better insulation material. When natural rubber vulcanization after the introduction of polarity factors, such as sulfur, accelerator, so that insulation performance.

Natural rubber hand wheel dielectric properties, natural rubber hand wheel is a non-polar material, it dissolves in non-polar solvents and non-polar oils. Natural rubber handwheel can not withstand cyclohexane, gasoline, benzene and other media, non vulcanized rubber can be dissolved in the above medium, vulcanized rubber hand wheel swelling. Natural rubber handwheel, insoluble in polar acetone, ethanol, more insoluble in water, resistant to 10% hydrofluoric acid, 20% hydrochloric acid, 30% sulfuric acid, 50% sodium hydroxide and so on.

The glass transition temperature of natural rubber raw rubber is -72 Deg. C, plastic flow temperature is 130 degrees centigrade, start decomposition temperature is 200 degrees centigrade, intense decomposition temperature of 270 DEG C. When the natural rubber wheel is vulcanized, its Tg rises, and no more viscous flow occurs.

Bakelite wheel performance:

PF bakelite (bakelite, bakelite) wheel surface material light, mechanical hardness is not easy deformation, friction resistance, corrosion resistance, aging resistance, easy to clean. The handwheel bakelite insulation performance is very strong and is not affected by heat and humidity, the temperature is greater than or equal to 140 degrees / Bakelite thermal deformation handwheel, strong cold resistance can work normally in the environment of thirty degrees below zero.
