Silicone Manufacturing Process

The video provides an in-depth look at the manufacturing process of silicone, highlighting the materials used and the steps involved in creating silicone sealants.

Introduction to Silicone

• Silicone is a versatile material used in various household applications, such as sealing surfaces like joints in bathrooms and kitchens.

• The primary solids used in silicone production are calcium carbonate and silicon polymer derived from silicon, extracted from sand through a complex chemical reaction.

Raw Materials Storage

• Raw materials like powders and liquids are stored separately in silos with large capacities to sustain production for several days.

• Liquids are stored in tanks with a capacity of 50 milliliters each, lasting about a week before being utilized.

Production Process Initiation

• The production process begins by mixing liquids using precise measurements on a scale before transferring them to a large tank along with powdered materials.

• Approximately 3,000 cartridges of sealant can be produced from this mixture.

Silicone Mixing and Formulation

This section delves into the mixing process of silicone components and the formulation secrets behind creating effective sealants.

Mixing Process

• A designated operator oversees the mixing process by adding raw materials based on a secret formula entered into a computer system.

• The mixture involves around 444 kilograms of materials that take approximately ten minutes to complete blending.

Curing Process

• A new liquid called "reseña" aids in curing the silicone, transforming it into rubber for sealing purposes.

• Another component known as reticular té is added to facilitate rubber formation, emitting a vinegar-like odor during the process.

Final Processing and Packaging

This part focuses on final processing steps post-mixing, including molding, quality checks, and packaging of silicone sealants.

Molding and Quality Assurance

• After mixing, the compound is transferred to molds where excess air bubbles are removed before closing for further processing.

Manufacturing Process of Silicone Products

The transcript discusses the detailed process of manufacturing silicone products, including the steps involved in preparing and packaging the silicone for distribution.

Preparation and Pressurization Process

• The piece that applies pressure to push and extract the silicone towards the packaging machine.

• Connecting the hose without letting the silicone escape under pressure, ensuring it is dense enough.

Packaging and Filling Stage

• Preparing the container for sealing, filling it with pressure from two dispensers.

• Daily cleaning routine before production, checking caps to prevent content spillage.

Color Customization and Mixing

• Introduction to pigment options for creating various colors using basic colorants.

• Utilizing injectors for mixing colors accurately based on requirements.

Silicone Varieties Based on Application

• Differentiating silicones by color variations such as pine or oak shades for specific applications like natural stone or aquarium sealing.

• Highlighting specialized silicones for distinct purposes like mirror installation or kitchen and bathroom use.

Quality Testing and Application Techniques

This section delves into quality testing methods for silicone products along with application techniques to ensure effective adhesion.

Quality Assessment through Testing

• Demonstrating a strength test using a dynamometer to measure adhesive force between materials.

• Explaining Newton's invention of the dynamometer used to gauge forces during testing processes.

Application Guidelines for Effective Adhesion

• Emphasizing surface cleanliness as crucial before applying silicone cordons to prevent support staining.
