The JIAYUAN Path to Quality. Innovation Paves the Way for High-Quality Development: Introducing the Dedicated Coating Line for Bonded Waterproof Boards!

In modern railway tunnel construction, waterproof boards are extensively used for drainage and waterproofing along tunnel ceilings. Current coating equipment for these boards faces significant limitations, particularly in ensuring uniform adhesive thickness during water-based glue application to the base material.

Addressing these shortcomings, JIAYUAN Machinery pioneered the development of this dedicated coating line for bonded waterproof boards as early as 2013. Utilizing composite material R&D principles and orthogonal design methodology, the solution was perfected through rigorous testing. Now a mature technology, the line is already in operation at multiple companies.

JIAYUAN Machinery's pioneering bonded Waterproof board coating line:

Unlocks new growth opportunities in the waterproofing industry

Opens new high-quality development pathways

Stimulates substantial market demand for premium waterproofing products

Production Process:

Coating: Self-adhesive glue is applied via a precision coating die, forming a uniform adhesive layer.

Anti-adhesion Spraying: Anti-stick coating is sprayed onto the adhesive layer.

Drying: The anti-stick coating is dried to form a protective film.

Winding & Packaging: Integrated winding and packaging ensure a seamless workflow.

Key Technological Advancements:

Added isolation layer process

Enhanced UV resistance coefficient of hot-melt adhesive

Resulting materials offer superior durability, system reliability, and safety

Meets market demand for high-quality, long-lasting, and secure waterproofing solutions

Product Advantages:

Prevents Water Channeling: Unlike conventional boards where groundwater seeps through breaches, bonded waterproof boards adhere to secondary lining concrete, forming an integrated parallel waterproofing system that blocks water migration.

Lightweight & Flexible: Easier to handle and install.

Eliminates Welding: No need for hot-melt gaskets, accelerating construction and preventing leaks caused by welding damage.

Superior Adhesion & Sealing: Bonds seamlessly with cast-in-place concrete, eliminating voids/air pockets behind the board and ensuring optimal waterproofing.

Driving Industry Transformation:

Opportunities for high-quality development, green initiatives, energy conservation, and eco-friendly manufacturing will phase out high-pollution, high-energy processes and equipment. This shift effectively promotes industrial upgrading and enhances product quality.

JIAYUAN Machinery's Commitment:

We will continue to intensify R&D investment, delivering products that offer:

Enhanced environmental sustainability

Superior waterproofing performance

Higher construction efficiency
