Inflatable pipe plugging airbag is a kind of rubber plugging equipment widely used in the engineering field, which plays an important role in pipeline construction, maintenance and temporary plugging in emergencies. The pipeline plugging air bag is inflated by the inflation method, and when the gas pressure in the air bag reaches it, the water blocking air bag fills the entire pipeline section, and the friction generated by the pipeline plugging air bag wall and the pipeline is used to block the leakage, so as to achieve the purpose of quickly blocking the water flow or airflow in the inner section of the pipeline. There are various materials for plugging airbags , including natural rubber material, butyl rubber material, ethylene propylene rubber material, nitrile rubber material, etc., the material with the best air tightness is butyl rubber, and has the characteristics of acid and alkali resistance, and is the most widely used in plugging rubber products. Due to the high price of butyl rubber, the production of inflatable pipe plugging airbags with part of HY butyl recycled rubber can effectively reduce product costs under the premise of ensuring quality.
Hongyun butyl reclaimed rubber production inflatable pipeline plugging airbag reference vulcanization formula is as follows, if used for production before first experimental testing:
1751 butyl rubber 3kg, hy butyl reclaimed rubber 40kg, HH-3 rubber reinforcing agent 10kg, N550 carbon black 3kg, talc 15kg, paraffin oil 5kg, ST137 phenolic resin 1.2 kg, Active zinc oxide 1.2kg, stearic acid 0.8kg, DM accelerator 0.3kg, TMTD accelerator 0.05kg, sulfur 0.5kg; vulcanization temperature 150-160 °C, vulcanization time according to the product.
The amount of butyl regenerated rubber added can be adjusted according to actual needs, and reasonable adjustment of the additive addition ratio can meet the performance requirements of the product and reduce costs. At the same time, selecting the appropriate vulcanizing agent and active agent can effectively improve the vulcanization speed and hardness of butyl regenerated rubber, thereby improving the service life and plugging effect of the plugging air bag. Butyl regenerated rubber generally uses petroleum plasticizers, such as paraffin, paraffin oil, ester plasticizers, etc.; The accelerator system can use 2 parts of ZDC or 5 parts of DM, or 60% TMTD accelerator and 40% M accelerator can be used together, using zinc oxide as an active agent, vulcanization rate, and can also prevent high temperature vulcanization from returning to the original; Butyl reclaimed rubber needs to pay attention to the amount of sulfur, when the sulfur content exceeds 1.5 parts, there will be frost spray phenomenon.
The vulcanization process of mixing butyl reclaimed rubber to produce inflatable pipes and plugging air bags requires mixer mixing to make various auxiliary materials mix evenly. The best effect is to park for about 6 hours after the vulcanization system and the promotion system, the rubber mixture is added to the mold and pre-pressed to ensure that the shape and size of the inflatable pipeline plugging air bag meet the requirements, and then the mold is placed in a preheated vulcanization tank to vulcanize the air bag. The vulcanization temperature and time should be controlled according to the specific situation to ensure that the vulcanization degree of the air bag meets the requirements.
The vulcanization formula and process mixed with YY23-811 butyl reclaimed rubber to reduce costs has multiple advantages:
1、Butyl recycled rubber as a waste rubber resource recycling is conducive to environmental protection and sustainable development.
2、Compared with the cost of using traditional butyl rubber, the use of butyl recycled rubber can greatly reduce production costs and improve production efficiency.
3、The optimized vulcanization formula and process can ensure the excellent performance of the inflatable pipeline plugging air bag, improve its service life and plugging effect.
Inflatable pipeline plugging air bag mixed with butyl recycled rubber to reduce costs, vulcanization formula and process is a technology with wide application prospects, which can not only reduce production costs, improve production efficiency of enterprises, but also promote environmental protection and sustainable development. Hongyun provides free vulcanization formula and process, and the use of new technology can not only reduce the cost of raw materials, but also realize the recycling of recycled rubber resources, which is of great significance to increase product competitiveness and broaden the market.
