Use Of Hand Wheel

Mainly used for machine tool equipment, printing machinery, textile machinery, packaging machinery, medical equipment, petroleum and petrochemical equipment, boiler lid accessories and so on.

Hand wheel production materials: bakelite, plastic and so on.

The main purpose of natural rubber hand wheel The natural rubber hand wheel is widely used in industry, agriculture, national defense, transportation, due to its strong elasticity, good insulation, plasticity, water and gas barrier, tensile and wear resistance. Transportation, machinery manufacturing, medical and health fields and daily life, such as tires for transportation; transport belts, transmission belts, various sealing rings for industrial use; medical gloves, blood transfusions; rubber shoes used in daily life, Raincoats, warm water bags, etc. are all made of rubber hand wheels. Aircraft, artillery, tanks used in national defense, and even rockets, satellites, spacecraft, and space shuttles in cutting-edge technology fields require large amounts of rubber. Handwheel parts.

The elasticity of the natural rubber handwheel is high in the elasticity of the vulcanizate whose raw rubber and crosslink density are not so high. For example, in the range of 0-100°C, the resilience is between 50-85°C. Its elastic modulus is only 1/3000 of that of steel, the elongation rate is up to 1000%, and it stretches to 350%. After that, it is retracted permanently. The deformation is only 15%, the natural rubber handwheel has a higher elasticity and is second only to the butadiene rubber handwheel in the universal rubber handwheel.

The strength of the natural rubber handwheel is in the elastic material, and the strength of the natural rubber handwheel rubber, rubber compound and vulcanizate is relatively high. The tensile strength of the unvulcanized rubber hand wheel is called the Green strength, and the green strength of the natural rubber hand wheel is up to 1.4 to 2.5 Mpa. The appropriate Green strength is necessary for the rubber hand wheel forming. The tear strength of the natural rubber hand wheel is also high, up to 98kN/m, and its wear resistance is also good. The reason for the high mechanical strength of the natural rubber hand wheel is that it is a self-reinforcing rubber hand wheel that, when stretched, orients the macromolecular chains in the stress direction to form crystals.

Natural rubber handwheel electrical properties Natural rubber handwheel is a non-polar material, is a good insulation material. When the natural rubber hand wheel is vulcanized, due to the introduction of polar factors such as sulfur, accelerators, etc., the insulation performance is degraded.

Media resistance of natural rubber hand wheels Natural rubber hand wheels are non-polar substances that dissolve in non-polar solvents and non-polar oils. Natural rubber hand wheels are not resistant to cyclohexane, gasoline, benzene and other media, unvulcanized rubber can be dissolved in the above medium, vulcanized rubber hand wheel swelling. The natural rubber handwheel is insoluble in polar acetone and ethanol, and is insoluble in water. It is resistant to 10% hydrofluoric acid, 20% hydrochloric acid, 30% sulfuric acid, and 50% sodium hydroxide.

The glass transition temperature of the natural rubber handwheel rubber is -72°C, the glue flow temperature is 130°C, the decomposition temperature starts 200°C, and the intense decomposition temperature is 270°C. When the natural rubber hand wheel is vulcanized, its Tg rises and no more viscous flow occurs.

Bakelite hand wheel performance: PF phenolic plastic (bakelite, bakelite) hand wheel surface bright, mechanical hardness is not easy to deformation, abrasion resistance, corrosion resistance, anti-aging, easy to wipe. The bakelite handwheel has strong insulation performance and is not affected by heat and humidity. The heat distortion temperature of the bakelite handwheel is greater than or equal to 140 degrees, and the cold resistance performance can work normally in the environment of minus thirty degrees.
