1, different materials
EPS component consists of high-strength flame-retardant polystyrene, alkali-resistant glass fiber grid cloth and inorganic anti-aging polymer emulsion.
GRC is glass fiber reinforced concrete.
2, the weight is not the same
GRC material is a kind of solid material, mainly cement, with heavy weight; The aggregate of EPS line is polystyrene, and its weight is about 1/6 of GRC decorative line.
3. The manufacturing process is different.
GRC line is a kind of cement slurry pouring product. This product is made by mixing cement cementing material with base material, spraying, vertical mold pouring, extrusion, slurry flow and other processes. The cost is high, the process is long, and mold opening is needed. After the product is finalized, it cannot be modified and needs to be remade.
EPS lines are designed and shaped by computer, and can be automatically cut without mold opening, with low cost. After the product is finalized, it can still be cut on site, the shape can be processed at will, and the production cycle of the product is short. Computer cutting EPS lines is convenient and fast.
4. The installation process is different.
When GRC line is installed, it is difficult to transport at high altitude, with high risk factor, requiring professional construction personnel, and the construction is unsafe. The installation adopts the method of welding and fixing the anchor bolts, which has the hidden danger of corrosion of the anchor bolts.
EPS wire is easy to carry, bonded by adhesive, and has high bonding strength. It can be cut, spliced and pasted at will, with high installation efficiency, low cost and safe and fast construction.
Second, advantages and disadvantages of EPS and GRC
The characteristics of EPS are: light weight, about1/6 of GRC decorative line; Paste firmly; Modeling and arbitrary processing; Convenient installation; Decorative lines (components) are smooth and beautiful, and there is no gap between lines.
Disadvantages: Because it is an EPS assembly line cutting and hanging production process, it is impossible to make too complicated decorative pieces (such as relief and mountain flowers).
GRC is characterized by infinite plasticity; Light weight and high strength; Ultra-thin technology and large size; Rich colors and diverse shapes; Good texture and many textures; Environmental protection, no radiation; Fireproof and waterproof; Anti-pollution, no deformation, super durable; Good sound insulation and seismic performance; Short construction period, convenient maintenance and easy replacement.
Disadvantages: The main material of GRC is sulphoaluminate low alkalinity cement, which is heavy in quality. If the installation is not well controlled, it is easy to have security risks. Due to the principle of thermal expansion and cold contraction, cracks are easy to appear at the joints after several years, which has not been broken through at home and abroad.
Third, the construction technology:
EPS construction process → basic preparation → measuring and setting out → pasting glass fiber grid cloth → pasting polystyrene board → fixing anchor bolts → plastering 3-5mm plastering mortar and pressing it into the grid cloth → insulation layer is completed.
GRC process flow construction lofting? → Installation of steel structure keel? → Fitting installation? → Select GRC board and lift it? → GRC plate bolted connection? → GRC board position adjustment? → Metrological inspection? → Welding of connectors? → Weld anticorrosion operation? → joint sealant of GRC board? → GRC wallboard is sprayed with fluorocarbon coating? → thermal insulation rock wool is packed and fixed? → Install the interior trim panel.
Fourth, the scope of application of EPS and GRC
Application scope of EPS components: residential buildings, villas, hotels, pavements, shopping malls, clubs and old city reconstruction, old building renovation, etc.
GRC components are suitable for all eaves decoration projects, such as painted walls and stone walls. Among them, the marble stone wall with GRC lines is the best.
Extended data:
GRC component, full name: GRC architectural detail decoration component. Code abbreviation: GRC architecture details. According to the national standard GB502 10-200 1 issued by the Ministry of Construction, GRC architectural detail decoration component belongs to a kind of architectural component in architectural decoration engineering detail engineering.
EPS component is made of high-strength flame-retardant polystyrene as the matrix, alkali-resistant glass fiber grid cloth as the middle layer, and the outer layer is compounded by inorganic anti-aging polymer emulsion. The product is light in weight and impact-resistant. High strength, good water resistance and good toughness. EPS components are made according to customer's drawings. The matrix is cut and shaped by numerical control cutting equipment, with precise structure, elegant appearance and delicate texture.
