Products That Can Be Made from Plastics and Sand
A wide range of products can be manufactured from waste plastics and sand, including:
Roof Tiles
Floor Tiles
Paving Blocks
Lumber Planks
Planter Pots
Kerbstones
Wall Panels
And many more construction-related products
Plastic Sand Production Process
The polymer sand production process consists of a series of production line machinery and is divided into two main stages: Pre-Processing and Core Processing.
Pre-Processing
Pre-processing involves shredding or densifying waste plastics, which are classified into two types:
Soft Plastics – Includes polyethylene bags, LDPE films, etc. These are typically shredded and densified using an agglomerator.
Hard Plastics – Generally includes HDPE materials such as milk bottles and bottle caps. These plastics are shredded into the desired size.
Pre-processing ensures the plastic material is appropriately sized for the Plastic Sand Extruder.
Core Processing
The core processing stage includes several essential systems:
Auto Loading System (ALS): Ensures controlled and uniform loading of plastics and sand into the plastic sand extruder.
Plastic Sand Extruder / Heating and Melting System (HMS): Melts plastics and sand into a uniform molten mass for molding.
Hydraulic Press: Compresses the molten mass into the desired end product.
Die Moulds: Customized moulds cater to various product requirements such as roof tiles, ceiling tiles, floor tiles, paving blocks, and kerbstones.
Chiller Plants / Cooling Towers: Aids in the rapid cooling of finished products to enhance durability and strength.
Die moulds with countless design possibilities
Advantages of Polymer Sand Products Over Conventional Materials
Polymer sand products offer numerous benefits over traditional materials like clay, cement, and wood:
Sustainability
Utilizes waste plastics and other commonly available fillers such as sand, M-sand, foundry sand, and other industrial waste including:
Glass powder
Foundry waste
Rock mining waste
Eco sand waste
Pond ash
ACC block dust
Construction debris
Gypsum waste
Chalk powder
Gravel waste
Performance Benefits
No Curing Time: Products can be used immediately after manufacturing.
Fire Resistant: Provides enhanced safety.
Fire Resistant Water-Resistant: Does not absorb water, preventing structural degradation.
High Compressive Strength: Offers superior durability compared to conventional materials.
Superior Durability Extended Lifecycle: Ensures long-term usage with minimal maintenance.
Recyclability
At the end of their lifecycle, polymer sand products can be recycled by being shredded and reused as filler material in the production of new products, further promoting sustainability.
Conclusion
Transforming waste plastics into polymer sand products provides an eco-friendly and sustainable alternative to traditional building materials. This innovative approach not only reduces plastic waste but also enhances the durability, strength, and versatility of construction materials. By adopting this technology, industries can contribute to a greener future while creating high-quality, long-lasting products.
