Common problems and solutions of butyl inner tube production

Author:

Huajun Tire Factory


In general, the common problems in the production of butyl inner tubes are mainly improper selection of raw materials, improper operation of the production process, and the production equipment cannot be cleaned in time, so be careful to select raw materials (including butyl rubber, reclaimed rubber and Various complexes),Shanxi butyl inner tube manufacturersIt said that by strictly implementing the established process operations, reasonably controlling the production process conditions, and cleaning and maintaining the production equipment in time, many defective products can be avoided.
1. Selection of materials.
There are two main methods for producing butyl inner tubes on the market, one is to use butyl rubber 1JLYY1120-SXC alone, and the other is to add a certain proportion of butyl reclaimed rubber to the inner tube products produced with butyl rubber as the main raw material., Can reduce production costs, but also can improve the processing performance of the compound. In practice, if butyl rubber, butyl reclaimed rubber and various compounding agents contain impurities, moisture or other volatile substances, it will bring inevitable problems for the production of butyl rubber.
2. The formula with the system.
In the production process, according to the special requirements of the inner tube, select the appropriate rubber and compounding agent, reasonable adjustment of butyl inner tube formula, under the premise of ensuring quality, reduce production costs and avoid defective products. Shanxi butyl inner tube manufacturers said, for example, if the dosage of butyl inner tube powder compounding agent is too large, the surface will be precipitated if the solubility of the rubber material exceeds, resulting in frost spraying in the inner tube. The amount of vulcanizing agent and accelerator in the vulcanization system is unreasonable, and the amount of sulfur is too small, which makes it easy to cause vulcanization and makes it difficult to produce butyl inner tube. Too low sulfur will cause sponge problems in the inner tube.

3. Reasonable control of the production process.
In the process of producing butyl inner tube, it is necessary to reasonably control the production process conditions, mainly including: mixing time, mixing temperature, vulcanization time, vulcanization temperature, taking model temperature as an example, under the conditions of vulcanization pressure and model temperature, when the butyl inner tube is vulcanized and finalized, the uneven temperature will directly lead to sulfur deficiency, which will cause the inner tube carcass deformation to increase and the tire body expansion. Insufficient vulcanization time is likely to cause the valve joint or valve rubber pad to appear under sulfur.
4. Regular maintenance of production equipment.
Shanxi butyl inner tube manufacturers said that when butyl rubber and butyl reclaimed rubber are used to produce inner tube products, the production equipment needs to be cleaned up in time, and the introduction of impurities or compounding agents in the production process of butyl inner tube is "endless trouble. Regular inspection and maintenance of the equipment, such as deformation or improper adjustment, will cause poor sealing model, rubber edge loss.
Although there will be various size problems in the production process, it is still the same sentence. If the materials are selected, the production process is reasonably controlled, and the equipment is inspected in time, the defective rate in the production of butyl inner tubes will be significantly reduced.
