It is not easy to make a good glass fiber reinforced plastic sculpture, which also has a number of regret works to a certain extent affected the reputation of FRP sculpture. High quality glass fiber reinforced plastic works must be made of all aspects of clever combination. In the most difficult and master production methods can produce natural relief carvings. According to the actual experience, Hebei, Quyang, China and Thailand garden sculpture Co., Ltd. will be made of glass fiber reinforced plastic sculpture of the 6 links to sum up.
1, design and modeling
FRP sculpture design should take into account the characteristics of material technology. Glass fiber is easy to form a beautiful streamline products, highlighting the work of the sense of the times, the design can be used to streamline the arc. Because of the light weight and high strength of the glass fiber reinforced plastic, the utility model can be used for producing a small area with strong dynamic support. Sometimes after surface coating, coating with leveling, curing in tension leveling have certain effect, not suitable for the performance of texture. These should be carefully considered in design. The original model can be clay sculpture, sculpture model is completed, natural drying, can be made of glass fiber reinforced plastic mold.
2, the production of glass fiber reinforced plastic
Hand paste method. According to the shape and characteristics of the sculpture, from the point of view of easy molding and demoulding, the mold is decomposed into several units. So as to form and combine them into a whole. Finally, the whole process of painting, a glass fiber reinforced plastic sculpture works will be completed.
3, mold production
Mold making is the key to forming. The mould is often made of gypsum, but it is low in strength and easy to deform. Can be made of silicone rubber and glass fiber reinforced plastic materials. Silicone rubber for use in the former state of flow, flow and filling good. The elastomer is formed by crosslinking reaction, which has a large elastic deformation. After crosslinking, the silicone rubber has good sealing property. The surface layer of the glass fiber reinforced plastic can be used to copy the shape of the product with high quality, and the mold can be smoothly released. However, it is easy to deform and support the carrier. It is used as the carrier of the mould by using the characteristics of glass fiber.
4, mold making method:
The silicone rubber is prepared, and the silicone rubber layer is coated on the original mold after 1mm. Silicone rubber was cross-linked to form the 3mm glass fiber reinforced plastic layer on the silicone rubber. After curing, the mold is cut along the divided cell block, and the glass fiber reinforced plastic layer is cut simultaneously. A positioning groove is arranged at the connecting rib of the connecting rib between the unit blocks, so as to ensure that the connecting rib can make the unit block mold into a whole. After the work is completed, the glass fiber reinforced plastic unit block is released, and then the silicone rubber layer is removed.
5, forming method
By using the method of hand paste, the design idea is made. From the end of the first part of a combination of paste products. Part of the cured and then continue to paste the mold combination. As many as possible combined unit blocks. Finally, a unit block is retained, and the unit block is pre molded to receive the whole sculpture. Similar parts of an animal's horns, legs, tail, etc., can be made in the shape of the corresponding metal material, and then the glass is formed on the material. The shape of the sculpture is more complicated and should be specially treated. It is difficult to put the glass on the resin, and then put the glass fiber and cloth. The surface of the resin putty with a length of 10 mm is appropriate, molding, metal skeleton buried in the sculpture. Improve the stiffness of the sculpture, increase the service life, and finally use the metal skeleton installation.
6, post-processing methods
On the one hand, the latter is to repair the local defects of the product, the importance of making surface effects. Common surface is imitation copper and bronze imitation. Made of glass fiber reinforced plastic sculpture bright color, lines, beautiful shape. Can be made into imitation gold, copper, stone a variety of effects, the performance of a distinct sense of the times. Good glass fiber reinforced plastic sculpture to design, model, molding, processing, to ensure the quality of each link can be achieved.
