Solution to Rubber Pollution Mold

Cause analysis

1. The mold material is not corrosion-resistant

2. Improper smoothness of the mold

3. During the rubber bridge construction process, acidic substances that corrode the mold are released

4. Substances with strong affinity to the mold generated during the rubber bridge construction process

5. Improper vulcanization of rubber leads to mold sticking

6. Release agents and other migration residues accumulate on the surface of the mold

7. Some adhesives and framework components may contaminate the mold due to adhesive contamination

Response plan

1. Mold material selection based on adhesive type

2. Control the machining accuracy of the mold

3. Reasonably use acid absorbing materials in the formula and skillfully use vacuum pumping

4. Mold surface treatment or addition of inert coating

5. Optimize vulcanization process

6. Reasonably use internal and external release agents as well as various additives with poor affinity to rubber

7. The adhesive process on the skeleton is in place

Cleaning method

1. Polishing machine polishing

2. Sandpaper polishing

3. Grinding paste grinding

4. Sandblasting

5. Soaking in hot alkaline solution

6. Special mold washing solution

7. Mold washing adhesive

8. Dry ice

9. Ultrasound
