The anti - corrosion rubber lining for flotation machine is of great significance in the flotation process, with the following details:
- Materials
- Natural Rubber: Some anti - corrosion rubber linings are made of natural rubber. It has good elasticity and wear resistance, which can adapt to the impact of ore pulp and other media in the flotation machine to a certain extent. In some environments where the corrosiveness is not extremely strong, natural rubber linings can play a good role.
- Neoprene: Neoprene is also a commonly used material. It has excellent resistance to aging, oil and chemicals. In the flotation process, when the ore pulp contains certain chemical substances or has a certain temperature, neoprene can maintain stable performance and is not easy to be corroded or aged.
- Styrene - Butadiene Rubber: Styrene - butadiene rubber is often used in anti - corrosion rubber linings due to its good heat resistance and wear resistance. It can resist the friction and erosion of ore pulp and other media in the flotation machine under high - temperature conditions.
- Properties and Functions
- Corrosion Resistance: The most prominent feature is its strong corrosion resistance. It can resist the corrosion of various acid, alkali and salt solutions in the flotation process, such as sulfuric acid, hydrochloric acid and sodium hydroxide solutions. This ensures that the metal shell of the flotation machine is not corroded by the slurry, thus prolonging the service life of the equipment.
- Wear Resistance: In the flotation process, the ore pulp and grinding media in the flotation machine will continuously rub against the lining. The anti - corrosion rubber lining has high wear resistance and can withstand long - term friction without significant wear, ensuring the normal operation of the flotation machine.
- Impact Resistance: When the flotation machine is working, the ore pulp and bubbles will produce a certain impact on the lining. The rubber lining has good elasticity and impact resistance, which can effectively absorb the impact energy and protect the internal structure of the flotation machine.
- Sealing Performance: The anti - corrosion rubber lining can also play a good sealing role, preventing the leakage of ore pulp and chemicals in the flotation machine, ensuring the stability of the flotation process and reducing environmental pollution.
- Noise Reduction and Vibration Isolation: The rubber lining has the characteristics of noise reduction and vibration isolation. It can reduce the noise and vibration generated during the operation of the flotation machine, improving the working environment and reducing equipment wear caused by vibration.
- Installation and Maintenance
- Installation: During installation, the surface of the flotation machine needs to be treated first to ensure its cleanliness and roughness to facilitate the bonding of the rubber lining. Then, the rubber lining is cut and pasted according to the size and shape of the flotation machine. Hot vulcanization or cold vulcanization technology can be used for bonding.
- Maintenance: In the process of use, it is necessary to regularly check the condition of the anti - corrosion rubber lining, such as whether there is wear, cracking or peeling. If any problems are found, timely repair or replacement should be carried out. In addition, avoid contact with sharp objects to prevent damage to the rubber lining.
