Artificial marble, also known as engineered marble, is a popular material in the construction industry due to its aesthetic appeal, durability, and ease of maintenance. The production process of artificial marble involves the use of molds that require effective release agents for a smooth surface finish. In this essay, we will discuss the working process of PVA water-soluble film for mold release during the production of artificial marble.

Working Process of PVA Water Soluble Film for Mold Release:

PVA water-soluble film is a type of polymer film that dissolves quickly in water, leaving behind a clean and smooth surface. The use of PVA water-soluble film for mold release in artificial marble production involves the following steps:

Step 1: Mold Preparation

The mold is cleaned thoroughly to remove any dirt or debris that may interfere with the film's adhesion.

Step 2: Cutting and Placing the Film

The PVA water-soluble film is cut to the shape and size of the mold and placed over the mold's surface. The film should fit the mold snugly to prevent any gaps or wrinkles.

Step 3: Pouring the Artificial Marble Mixture

The artificial marble mixture is then poured into the mold. The PVA water-soluble film acts as a barrier between the mold and the mixture, preventing the artificial marble from sticking to the mold during the production process.

Step 4: Curing

The artificial marble is left to cure, allowing the mixture to solidify and take the shape of the mold.

Step 5: Removing the Film

Once the artificial marble has cured, the PVA water-soluble film can be easily removed by washing the mold with water. The film dissolves quickly in water, leaving behind a clean and smooth surface.

In conclusion, PVA water-soluble film is a crucial component in the production of artificial marble. Its use as a mold release agent ensures a smooth surface finish, prevents sticking to the mold, and is environmentally friendly. The working process of PVA water-soluble film for mold release during the production of artificial marble involves mold preparation, cutting and placing the film, pouring the artificial marble mixture, curing, and removing the film. This process is simple and effective, resulting in high-quality and aesthetically appealing artificial marble.
