PVC 1800mm×7800mm – Laminate

I. Overview

This product is an extra-large, high-density rigid PVC solid sheet, specifically designed for demanding industrial corrosion protection and structural applications. Standard dimensions are 1700mm wide and 7800mm long, with thickness customizable to project requirements (typically 15-50mm).

Its core purpose is as a structural main body material for large-scale, all-plastic corrosion-resistant equipment (such as hydrometallurgical extraction tanks, chemical storage tanks, electroplating tanks, etc.). By providing sheets far exceeding conventional sizes, it aims to fundamentally reduce the number of welds and joints during equipment manufacturing, thereby significantly improving the overall sealing reliability, structural strength, and service life of the equipment. It is a key engineering material for solving the corrosion protection challenges of equipment in large-area, highly corrosive environments.

II. Production Process

Production Process: Raw material mixing → Extrusion/calendering into substrate → Overlaying and combining with decorative layer, wear-resistant layer, and balancing layer → Feeding into a multi-layer hot press for lamination and fusion under high temperature (approximately 160-200°C) and high pressure → Cooling → Cutting → Finished product.

III. Key Features and Advantages

Superior Size Advantage (Core Advantage): Reduced welds, enhanced safety. When manufacturing large tanks, using this specification of plate significantly reduces welds. Welds are the weakest points in corrosion-resistant equipment, making them the most vulnerable to failure. Reducing welds means lowering the risk of leakage and enhancing the overall structural integrity and long-term operational safety.

Increased Efficiency and Reduced Costs: Faster assembly saves welding time, materials, and inspection costs, shortening equipment manufacturing cycles.

Excellent Chemical Corrosion Resistance: Excellent resistance to a wide range of inorganic acids, alkalis, and salt solutions (especially hydrochloric acid, sulfuric acid, and mixed acids). Its corrosion resistance is superior to stainless steel (such as 304 and 316L) in many environments.

This characteristic makes it an ideal alternative to expensive special metals in industries such as hydrometallurgy, chemical processing, electroplating, and pickling.

Superior Physical and Mechanical Properties: 

High Strength and High Rigidity: High density (1.4-1.6...) (g/cm³) gives it excellent bending resistance, impact resistance, and pressure resistance, making it suitable for use as a load-bearing structure.

100% Impermeable: Solid homogeneous structure, completely impermeable to water and air, ensuring media purity and environmental safety.

High Machinability: Easy to machine using sawing, planing, drilling, milling, and other mechanical methods.

Hot Air Welding Capable: Strong, permanent connections with high body strength can be achieved using homogeneous welding rods and professional hot air welding technology, the technical basis for manufacturing large sealed containers. Weld seams can be inspected to ensure their airtightness.

Weather Resistant and Anti-Aging: The added UV-resistant components allow for long-term outdoor use.

Flame Retardant and Insulating: Typically self-extinguishing and with good electrical insulation.

Smooth Surface: Not prone to scaling, easy to clean and maintain, reducing material residue and contamination.
