新聞摘要:Compact structure, small volume, convenient disassembly and maintenance
Because the greatest advantage of GRC is its high plasticity, so the dimensions of each project component are not the same. After getting the drawings, carry out the detailed design twice to confirm the grid division and installation node. Make the mould according to the production mode confirmed in the drawing. Spray production with GRC special equipment (there are several production processes in total, the best one is mechanical spray, please refer to GRC component industry standard for process technology). Repair after demoulding.
When the GRC is made by spraying method, the cement mortar and the chopped ar glass fiber are sprayed to the appropriate mold from the spraying head at the same time. The cement mortar is fed into the spray gun by an adjustable pump and dispersed into particles by compressed air. Ar - glass fiber roving is fed into the cutting of the spray head to a predetermined length, so that the cut short raw yarn is sprayed into the dispersed mortar, so that a uniform fiber sand slurry layer can be formed on the mold.
The premixing method is to mix cement, sand, water and admixture in the short cut ar fiber sand in a mixer, and then form. First of all, it is necessary to make high-quality slurry, which not only has the necessary workability, but also can make the fiber disperse evenly; secondly, the fiber is mixed into the slurry. According to the different forming methods, the premixed process can be divided into premixed pouring process and premixed spraying process. The process of premixed pouring is similar to that of precast concrete products, and vibration process is often supplemented in the process of pouring.
GRC sprayer adopts the inclined screw pump composed of two-phase high wear-resistant stainless steel rotor and PTFE stator. The spray machine has the advantages of uniform feeding, no obvious pulse, uniform ratio of GRC products, good product uniformity, reasonable design, compact structure, small volume, convenient disassembly and maintenance.
The CVT control technology is used to adjust the flow and achieve better spraying effect. The working area is large. The diameter of the horizontal arm of the spray gun and the feed pipe is up to 10 meters. With the extension of the hose, the working area can reach 120 square meters without moving the platform. Construction efficiency is high, quality is good, volume is small, easy to handle on site, accessories are easy to buy, cost is low, suitable for spraying materials: Mortar (GRC mixed glass fiber short cut wire), gypsum, magnesia cement, relief effect coating, waterproof materials and small villas, clubs, bridges, rockeries, dams, river guardrails, etc. GRC jet machine can produce GRC line, GRC column head, GRC column base, GRC column pier, GRC bare column, GRC relief, GRC flower pot, GRC Lanhe, GRC window cover, GRC door cover, GRC fountain, GRC Plate, GRC garden sculpture, etc.
The spray process overcomes the shortcomings of the conventional GRC production process, such as mesh laying and premixing. The glass fiber can be evenly distributed in the cement mortar in two-dimensional direction according to the predetermined length and content. The GRC with better quality can be obtained. It is suitable for making thin products and has great flexibility in cross-section shaping.
