Identification and treatment of the cause of rubber blooming

Frosting is a common problem in the production and use of rubber products. It affects the appearance of the product, and directly affects the performance of the rubber product and shortens the service life. It is of great significance to identify the cause of rubber blooming in time and choose an appropriate method to optimize the quality of rubber products and improve the yield of rubber products. Autumn has already come quietly, and the rubber products parked in the warehouse sometimes have frost problems. Why?

In the actual production and use process, there are many reasons for rubber blooming, such as insufficient sulfur, improper storage conditions, raw material fluctuations, improper process operation, improper dosage of compounding agents, etc.

1. Lack of sulfur: The blooming of rubber products due to lack of sulfur is local, and the vulcanization process adjustment and vulcanization system need to be improved.

2. Storage conditions: When rubber products are sprayed due to improper storage, different comparison tests of storage temperature, time and humidity are required. Proper storage conditions can completely avoid this kind of spraying.

3. Fluctuations of raw materials: The blooming problems of rubber products due to the fluctuations in the quality of raw materials appear in batches. The comparison test of different batches and origins of the raw material 2LLYY916 can be identified. In actual production, as long as the quality of the raw materials is ensured, the replacement of raw materials that have experienced quality fluctuations can be solved.

4. Process operation: problems such as wrong or missing weighing of rubber product compounding agents will cause partial blooming of rubber products. When the staff weigh the compounding agents, they should be accurately weighed to avoid problems such as mismatching, over-mixing, less-mixing, and omissions, and ensuring uniform mixing of the rubber material can effectively prevent this kind of blooming phenomenon; during the rubber mixing process, It is necessary to carry out production in strict accordance with the established production process, keep abreast of the production process, strictly control the roller temperature, and avoid partial blooming of rubber products.

5. Rubber aging: In summer, especially in summer, the temperature is high and the sun is poisonous. Rubber products are prone to aging and frosting in the environment of high temperature and sun exposure. For this reason, rubber products manufacturers can choose to mix other rubbers and increase the amount of antioxidants. Ways to avoid blooming.

6. Excessive amount of compounding agent: Improper amount of compounding agent is the main reason for the blooming of rubber products. Rubber product manufacturers need to judge which kind of compounding agent is caused by the excessive amount of spraying according to the color, location, area, etc. It can be solved by adjusting the formula appropriately. In summer, the powdery compounding agent has high solubility in the rubber compound, and the amount of it is not obvious at the time. However, the problem of frosting of rubber products will occur in autumn and winter. This requires special attention. The amount of compounding agent must be strictly controlled. Climate change adjusts in time.

Blooming is a common problem in the production, parking and use of rubber products. Rubber product manufacturers need to take appropriate measures to solve the problem according to the cause of the blooming problem. In actual production, rubber product manufacturers timely detect the quality of raw materials, rationally design rubber product formulas, and strictly control production process operations can effectively solve the problem of blooming, improve the yield of rubber products, and avoid unnecessary losses.
