Cement pipe rubber sealing ring is a rubber sealing element used at the connection of cement pipes, mainly used to:
1. Sealing effect: The rubber sealing ring is placed at the connection of the cement pipe and is sealed with the inner and outer walls of the cement pipe to prevent leakage
2. Anti corrosion effect: Rubber materials themselves have a certain degree of oil resistance, acid and alkali resistance, which can prevent corrosive media from corroding cement pipes
3. Anti seepage effect: The rubber sealing ring is combined with the sealing of the inner and outer walls of the cement pipe to prevent liquid from seeping into the surrounding medium of the pipeline
4. Reinforcement effect: The rubber sealing ring placed at the cement pipe connection can enhance the strength of the cement pipe connection and prevent cracking and leakage
5. Shock absorption effect: Rubber materials have good shock absorption and buffering effects, which can reduce water hammer effect and shock absorption
Therefore, the rubber sealing ring of cement pipes is a rubber sealing element used at the connection of cement pipelines. Through its sealing, anti-corrosion, anti-seepage, reinforcement, and shock absorption functions, it ensures the safe and reliable operation of cement pipelines. It is an indispensable and important sealing product in pipeline engineering
The use of recycled tire rubber to produce cement pipe rubber sealing rings has the following benefits 23y5y15:
1. Lower cost. The raw materials for tire regeneration rubber mainly come from waste tires, which are cheaper and can significantly reduce the cost of cement pipe rubber sealing rings
2. Resource conservation. The use of recycled rubber from waste tires can save a large amount of natural rubber resources and has environmental protection significance
3. The performance can meet the requirements. The rubber elasticity, oil resistance, and weather resistance of recycled tire rubber can meet the requirements for the use of cement pipe rubber sealing rings
Rubber sealing ring for cement pipes uses latex recycled rubber - reference formula for tire recycled rubber:
40kg of tire recycled rubber, 4kg of 100% black latex recycled rubber, 4kg of N330 carbon black, 5kg of lightweight calcium carbonate, 0.33kg of paraffin, 0.33kg of paraffin, 1.2kg of coumarone, 0.22kg of 4010 antioxidant, 0.95kg of zinc oxide, 0.5kg of stearic acid, 0.2kg of CZ accelerator, 0.24kg of DM accelerator, 0.2kg of TMTD accelerator, and 0.5kg of sulfur. The vulcanization time and temperature are adjusted appropriately according to the thickness of the product. The strength of the cement pipe rubber sealing ring is 8Mpa, the elongation at break is 300%, and the Shore hardness is 65 degrees
From the above formula, it can be seen that tire recycled rubber is the main foundation, and an appropriate amount of latex recycled rubber is used to supplement and improve the tensile strength. Zinc oxide incremental vulcanization can produce a higher cross-linking density. Add an appropriate amount of plasticizer, reinforcing agent and anti-aging agent to adjust the performance of rubber seal ring. The addition of fillers such as carbon black is also crucial, directly affecting the strength, sealing performance, and service life of the product
The use of recycled tire rubber can reduce the cost and resource consumption of cement pipe rubber sealing rings, and the use of scientific and reliable formula design can meet the performance requirements of the product. But it is also necessary to test and evaluate the performance of recycled tire rubber to ensure that it meets the usage standards.
