How to store tire reclaimed rubber is not only a problem to be considered by reclaimed rubber factories, but also must be understood by every manufacturer that uses rubber reclaimed rubber to produce rubber products. Imagine: Whoever pays for the responsibility for rubber products manufacturers who have purchased tires with reclaimed rubber from reclaimed rubber plants due to improper storage of their own products, causing the index of reclaimed rubber to decline or even become unusable? Therefore, for rubber product manufacturers, understanding the storage conditions and parking methods of tire reclaimed rubber is as important as selecting a tire reclaimed rubber product.
The raw material of the tire reclaimed rubber is the waste rubber tire, which is processed by a special process, and is a replaceable rubber species of the original rubber. It is the same as all the reclaimed rubber (including natural rubber, synthetic rubber, and reclaimed rubber), and the most in the storage process. The fear is ultraviolet light and ozone, which requires us to park tire reclaimed rubber indoors, to avoid sun exposure and ozone erosion.
Water is the source of human life, but the storage of tire reclaimed rubber is very afraid of water, and not to mention that the long-term contact of moisture with tire reclaimed rubber leads to the water-soluble substances and hydrophilic groups in the reclaimed rubber of the tire being extracted by water. Dissolved, hydrolyzed or absorbed, so as to destroy the performance of reclaimed rubber products; single storage of tire reclaimed plastic warehouse humidity will have an impact on the performance of reclaimed rubber products. Therefore, tire reclaimed rubber must pay attention to waterproof and moisture-proof in the storage process, especially in the humid south; tire reclaimed rubber storage warehouse must be kept ventilated, but should not be excessive or strong wind, and stored off the ground.
Tire reclaimed rubber in the production process need to add the right amount of rubber oil, parking will occur during the loss of oil, so that the impact of tire reclaimed rubber flexibility, flex cracking resistance, affect the production of reclaimed rubber products And the service life. In order to solve the problem of loss of tire reclaimed rubber seal, it is advisable to cover the felt cloth / canvas on the surface during storage to ease the loss of tire reclaimed rubber oil.
In the storage process, tire reclaimed adhesives also need to pay attention to the problem of Mooney viscosity rebound. We will not elaborate on them anymore. Under proper storage conditions (26 ℃ in summer and 20 ℃ in winter), good performance can be maintained within two years after the reclaimed rubber is put down the production line. After two years, oil reduction and plasticity will decrease. However, it is not impossible to use it. It is only necessary to add some grease in the process of use and then use an open mill to open it several times.
The storage conditions and parking methods of latex reclaimed rubber, butyl reclaimed rubber, nitrile reclaimed rubber, EPDM reclaimed rubber, and isoprene reclaimed rubber are not exactly the same as those of tire reclaimed rubber. Related issues will be later. Discuss with everyone.
