A Century of Innovation in Plywood-Qiangyi glutinous rice plywood

The Historical Origins of Qiangyi glutinous rice glue plywood

The Great Wall has stood for thousands of years not only because of its thick bricks and stones, but also because of the adhesives(glue) used in its construction . In terms of construction materials, Ming Dynasty craftsmen creatively used a magical “biological adhesive”—glutinous rice mortar. They mixed cooked glutinous rice glue with slaked lime and sand to create a paste. The amylopectin in the glutinous rice reacted chemically with the lime, producing an exceptionally strong, durable, and waterproof organic-inorganic composite material. This is the key to why many sections of the Great Wall remain tightly bonded even after centuries of wind and rain erosion. Today, this ancient wisdom has been reborn through modern technology. The new “glutinous rice glue plywood” uses the same glutinous rice adhesive technology as the Great Wall.

Overview of Qiangyi glutinous rice glue plywood：

The innovation behind glutinous rice plywood lies in drawing inspiration from the principles of the ancient Great Wall. Qiangyi glutinous rice glue plywood also name as second-generation plywood that represents a century of innovation. It has achieved No.1 in selling and top reputation in China. Widely favored by renovation companies, cabinet manufacturers, and homeowners. It uses 0-formaldehyde, 0-benzene Lingmei glutinous rice glue as the adhesive, select all AA grade eucalyptus veneer as the core material, adding magnesium chloride and water and magnesium oxide. Magnesium oxide is a super flame retardant and heat insulation agent, with its own ignition point reaching 2852℃, this made Qiangyi glutinous rice plywood achieve B1 grade fire retardant standard (B3: Flammable Materials; B2: Combustible materials). Glutinous rice glue after curing, creates an alkaline environment, while termites and insects prefer an acidic environment. Combined with its strong permeability, termites ingest some of the glutinous rice glue along with the wood fibers. The alkaline nature of the glue isindigestible, leading to death. This glutinous rice glue is made from pure plant/mineral extracts, ensuring safety and stability. It does not involve aldehyde chemical reactions, thus eliminating the introduction of formaldehyde at its source resulting in exceptional environmental performance, achieving super ENF-level environmental protection. Cold-pressed and self-heating molding allows for immediate occupancy after installation. In terms of performance, the combination of primary veneer and glutinous rice glue, processed through multiple layers, endows it with strong nail-holding power, resistance to deformation, flame retardancy, water resistance, moisture resistance, mildew resistance, antibacterial properties, and termite resistance, making it a second-generation multi-layer plywood and a “nine-sided warrior” in the plywood industry.
