Other Handwheel Performance

The flexibility of natural rubber hand wheel Its raw rubber and crosslinking density is not too high vulcanizate elasticity is high. For example, in the range of 0-100 ° C, the resilience is between 50-85 ° C, the modulus of elasticity is only 1/3000 of the steel, the elongation is up to 1000%, the elongation is 350% Only 15% deformation, natural rubber hand wheel high elasticity, universal rubber handwheel second only to butadiene rubber hand wheel.

The strength of natural rubber hand wheel In the elastic material, natural rubber hand wheel raw rubber, rubber, vulcanizate strength is relatively high. Tensile strength of unvulcanized rubber hand wheel is called Green strength, Green strength of natural rubber handwheel up to 1.4 ~ 2.5Mpa, the appropriate Green strength is necessary for the processing of rubber hand wheel molding. Natural rubber hand wheel tear strength is higher, up to 98kN / m, its wear resistance is also better. The reason why the mechanical strength of natural rubber handwheel is high is that it is a self-reinforcing rubber hand wheel that will crystallize the macromolecular chains in the direction of stress when stretched.

Electrical Properties of Natural Rubber Handwheels Natural rubber handwheels are non-polar materials and are a good insulating material. When the natural rubber hand wheel vulcanized, due to the introduction of polar factors, such as sulfur, accelerators, so that the insulation properties decline.

Resistance of natural rubber hand wheel performance Natural rubber hand wheel is a non-polar material, it is soluble in non-polar solvents and non-polar oil. Natural rubber hand wheel impatient cyclohexane, gasoline, benzene and other media, unvulcanized rubber can dissolve in the above medium, vulcanized rubber hand wheel is swollen. Natural rubber hand wheel insoluble in polar acetone, ethanol, but less soluble in water, resistant to 10% hydrofluoric acid, 20% hydrochloric acid, 30% sulfuric acid, 50% sodium hydroxide and so on.

The raw rubber of natural rubber has a glass transition temperature of -72 ° C., a flux temperature of 130 ° C., a starting decomposition temperature of 200 ° C. and a severe decomposition temperature of 270 ° C. When the natural rubber hand wheel vulcanized, its Tg rise, no longer occur viscous flow.

Bakelite hand wheel performance:

PF Bakelite (Bakelite, bakelite) material hand wheel surface bright, strong mechanical hardness is not easy to deformation, abrasion resistance, corrosion resistance, anti-aging, easy to wipe. Bakelite handwheel insulation performance is extremely strong and not subject to heat and humidity, bakelite handwheel heat distortion temperature greater than / equal to 140 degrees, cold hardiness can work in the normal environment of minus thirty degrees.
