Nitrile regeneration rubber is a new recyclable material made of waste nitrile rubber through desulfurization and recycling, with excellent oil resistance, wear resistance, acid and alkali resistance, etc., and is widely used in automobiles, machinery, chemical industry and other fields; In these areas, rotary shaft lip seals are an indispensable component that effectively prevents liquid or gas leakage and keeps the machine running. The use of nitrile reclaimed rubber to produce rotary shaft lip seals has become a new way to reduce costs under the premise of ensuring quality, and some enterprises can reduce raw material costs by about 20% after use.
Vulcanization formula and process for the production of lip seals with nitrile regenerated rubber
Nitrile regenerated gum 40kg, 3305E nitrile gum 5kg, N550 carbon black 4kg, light calcium carbonate 12kg, dioctyl ester 4kg, Paraffin wax 0.3kg, polyethylene glycol 1kg, zinc oxide 1.5kg, stearic acid 0.7kg, RD antioxidant 0.3kg, anti-scorch agent 1.2kg, CZ accelerator 0.2kg, DM accelerator 0.22kg, TMTD accelerator 0.1kg, sulfur 550g, vulcanization temperature 155 °C, vulcanization time according to the thickness of the product.
In the process of producing lip seals, experiments and tests are required to ensure the quality of the product, and the experimental data and test results can reflect the advantages and disadvantages of the vulcanized formulation process and the performance of the lip seals. For example, tensile tests, hardness tests, oil resistance tests, wear resistance tests, etc. can be performed to evaluate the performance of lip seals. Experimental data and test results can be used to optimize vulcanization formulation processes and improve production processes.
Nitrile reclaimed rubber production rotary shaft lip sealing ring has the advantages of good environmental performance, strong oil resistance, good wear resistance, good acid and alkali resistance, and low cost. With the continuous improvement of environmental awareness and the continuous advancement of technology, nitrile regeneration rubber production rotary shaft lip sealing ring will be more widely used and promoted.
