Production principle:
After high strength and high performance
concrete developed in building materials, people didn’t satisfied, in 1990s, they
developed a new super high strength, durable, high toughness and steady concrete,
which is mixed by DSP materials and fiber enhanced materials.
Jinsheng researched this technology, and
manufactured our own RPC formula and production technology, with our own
patent. We use Super high strength cement, quartz flour, SiO2, Carbon/copper plating
steel fiber, and other materials, through our automatic production line, and
serious management for raw materials and production.
Production process:
RPC board is made of high-strength cement, quartz powder and siliceous material (mainly composed of SiO2) and admixtures, with a proper amount of copper-plated steel fiber or carbon fiber added as reinforcement material. Through each powder bin, liquid bin and fiber bin, the material is divided, batched, stirred and transported to the assembly line to enter the mold box (template) for vibration, rolled and then molded at a constant temperature of 40 degrees and steamed at 80 degrees or above A new type of material with high pressure, high strength, high toughness, excellent weather resistance, impermeability and heat insulation is made by pressing curing, drying, sorting, warehousing and other processes.
High quality RPC:
RPC board is different from the traditional cement board production, it has higher requirements for technical formula and production equipment. The production of high quality RPC board depends on the quality of raw materials, process formula, advanced production equipment and management experience. The product can be sawed, drilled, nailed, planed and other processing. The surface of RPC board can be processed with concave convex anti-skid decorative pattern by die box design. It can be widely used in construction engineering such as power plant, high-speed railway, intercity railway, subway bridge and tunnel, municipal engineering trench cover plate, cable trench cover plate, such as steel structure of construction engineering, interior wall enclosure of wood structure building, floor partition plate and sports , sound absorption board of theater and meeting room, stair pedal, etc.
Advantages of Jinsheng RPC Cover plate
1. High
strength
2. Steady
physical performance: 60 times Freezing thawing experiment without any
changing
3. Durable
save cost for curing and replacing
4. Light
weight: less thickness can reach same performance with traditional cover plate
5. Fireproof
6. Dump
proof
7. Easily
modeling
The RPC cover plate often be used for covering the drain water draintage ditch or cable trench of the railway, Municipal engineering and evacution platform.
