The Preparation Process and Raw Material Selection of Acid-Resistant Asbestos Rubber Sheets

The Preparation Process and Raw Material Selection of Acid-Resistant Asbestos Rubber Sheets

Acid-resistant asbestos rubber sheets are an important industrial material. They are widely used in the chemical industry, power equipment, and environmental protection. Asbestos rubber sheets are acid and alkali resistant. They can resist high temperatures. They are electrically insulated and have good rubber elasticity. These traits make them very popular. In preparation, choosing the process and raw materials is crucial. This article looks at how to prepare and choose raw materials for acid-resistant asbestos rubber sheets.

We divide the process into the following steps:

1. Raw material prep: Select a suitable amount of asbestos fibers. Then, crush, loosen, and screen them. This ensures uniformity and the right fiber length. At the same time, choose high-quality rubber as the adhesive.

2. Preparation of rubber adhesive: Crush, heat, and process the rubber. This makes rubber particles or flakes to serve as a curing matrix for later processes. Also, one can add fillers and hardeners to improve the rubber’s performance, depending on the requirements.

3. Add fillers, like carbon black, to the rubber adhesive. This will increase the strength, hardness, and tensile strength of the rubber sheet. Choose fillers based on their properties. They must also suit the rubber adhesive.

4. Mixing and preparation: Mix the treated asbestos fibers with the rubber adhesive and fillers. Ensure a uniform dispersion. The rubber adhesive must coat the asbestos fibers and form a uniform mixture.

5. Molding: Place the mixture into a preformed mold and subject it to heat and pressure for molding. The right temperature and pressure cure the rubber adhesive. This bonds the asbestos fibers and the adhesive.

6. Curing: After molding, the sheet must cure. This will improve its wear and corrosion resistance. You can cure it using heat or other chemical treatments.

Secondly, select raw materials for acid-resistant asbestos rubber sheets. Consider these aspects:

1. Selection of asbestos fibers: Use high-quality asbestos fibers. They must resist acid, alkali, and high temperatures. This ensures the finished sheet’s quality. Commonly used asbestos fibers include long and short asbestos fibers. The choice depends on different engineering needs.

2. Select rubber adhesives. They must resist acids, alkalis, and high heat. Common rubber adhesives are natural rubber, styrene-butadiene rubber, and ethylene-propylene rubber. You can choose one based on your specific needs.

3. Selection of fillers: Choose fillers for their effect on the rubber sheet’s performance. Common fillers are carbon black and calcium silicate. Choose based on needs and the correct ratios.

4. Selection of hardeners: Choose hardeners based on the required ratio. This will ensure the sheet has good hardness and wear resistance after curing. The selection of hardeners can include vulcanizing agents or other chemical reaction agents.

In summary, the prep and choice of materials are key to the performance of acid-resistant asbestos rubber sheets. In prep, quality control must be at each step. This ensures the product’s stability and consistency. Choose asbestos fibers, rubber adhesives, fillers, and hardeners as the raw materials. Select them based on different engineering requirements and usage environments. High-quality, acid-resistant asbestos rubber sheets need good raw materials and careful preparation.
