What are the crafts of the water park equipment , what materials are included, and the production process. Let's take a look at the following.
Tools: Tools required for FRP production include: plastic buckets, plastic buckets, brushes, scissors, gloves, trowels, rollers and some small power tools.
Selection of water park equipment (forming mold): According to the appearance requirements of the parts, choose the mold molding or the male mold molding, and the tread surface is a smooth surface. Produce master molds according to drawings or prototypes. The molding die is manufactured in accordance with the production master. The material of the molding die and the master mold may be metal, wood, gypsum, epoxy resin filler, and glass fiber reinforced plastic.
Selection of Resin Type Unsaturated polyester resin refers to an organic polymer compound having a linear structure and having a low molecular weight and having a repeating ester bond and an unsaturated double bond in the main chain. The state of the finished product is the styrene solution of the linear unsaturated polyester, which cannot be stored for a long time. The cured product is a bulk structural copolymer of styrene and unsaturated polyester, and has insoluble and infusible properties. Due to the different molecular structure, the performance of their products is not the same. Therefore, there are different resin grades, which can be divided into general-purpose, anti-corrosive, self-extinguishing and heat-resistant types according to their performance. The commonly used ones are 191DA#, 191DC#, etc., which are hard and rigid and can be used for FRP products. 196# Resin is a flexible resin that improves the brittleness of FRP products.
Selection of accelerator and curing agent: The curing agent is benzoyl dibutyl peroxide paste, which needs to be stirred evenly. The accelerator is a cobalt naphthenate styrene solution, a purple liquid.
Reinforcing agent: Glass fiber is the main reinforcing agent. Including surface felt, chopped fiber mat, carbon fiber and various fabrics. The amount of reinforcing agent will affect the performance of the FRP product. Too little reinforcing agent will affect the rigidity of the product and make the brittleness too large. Too much content can easily cause poor impregnation of the product and cause delamination. The product has poor toughness. Hand lay-up mainly uses non-woven fabrics and chopped strand mats.
Surface felt: A type of felt in which the fixed length monofilament is bonded into a book. It has a fast dipping speed and can absorb a relatively large amount of resin, and the coverage is good. Can be used to lay the surface of FRP products, cover up
Glass fiber, which strengthens the strength of the gel coat resin layer and makes the surface of the product smooth. Generally replaced with 016 glass fiber cloth.
Short-cut fiber mat: A kind of felt formed by chopping a short-cut fiber of a certain length and evenly interlacing it in a plane. It can absorb a large amount of resin and can be mixed with non-woven fabric or used alone.
Plain cloth, twill: These two kinds of cloth have good bubble removal, easy to penetrate and good layability. The thickness is 0.1 mm; 0.2 mm; 0.3 mm; 0.4 mm, and the like. Covering the surface of the product can increase the appearance of the product.
Carbon fiber: good strength and high price. If there is no special requirement, it is rarely used. Different thicknesses of felt and cloth can be used depending on the appearance requirements and structure of the part. Generally, the first layer of surface felt should be used, the second layer should be chopped strand mat, and then the plain weave should be used until the thickness of the structure. Special circumstances can be selected by the process depending on the situation.
Thixotropic agent (filler): mainly composed of vapor phase SiO2 (white carbon black), talc powder, and the like. When the room temperature is high, the fluidity of the glue is large, and the glue is easily generated in the production. To change this condition, white carbon black or talc may be added. The amount added is determined by the process as the case may be.
Gel coat resin and polyester paste: gel coat resin: to change the surface brightness of FRP products, improve corrosion resistance, heat resistance, water resistance and weather resistance, extend product life, and make a high resin content on the surface of the product. The top layer is called the gel coat layer. Gel coat resin is a special resin for the top layer. When the right to use, the curing agent and the accelerator are used in the same amount as the other resins. Product coating thickness: The thickness of the gel coat layer of the part is 0.25mm-0.4mm, that is, 300g-400g per square meter.
Brushing method: The gel coat resin should be applied twice, and the second brush should be applied after the first basic cure. The gel coat resin should not be made too thin, otherwise it will not cure completely, and the appearance of the glass fiber under the gel coat will also be revealed. If it is too thick, it is prone to cracks and cracks and is not resistant to impact. If it is not uniform, it will cause cracks. This is because the surface curing speed is different and internal stress is generated. The gel coat resin may be a pure resin, and if necessary, may be reinforced with a glass fiber surface felt or surface imperfection.
Polyester paste: It is made of various inorganic pigments, mixed into linear resin, and is made by three-roll mill. It is pressed several times and has good mutual compatibility with resin. It is sufficient that the color paste is added in an amount required to achieve the desired depth and opacity. A suitable polyester paste should not be added in an amount exceeding 10% of the amount of the resin.
Release agent: The role of the release agent is to allow the parts to be smoothly peeled off from the mold without damaging the parts and the mold. F-103 release wax produced by Meguiar's Company of the United States.
Analysis of raw materials for water park equipment
The water park focuses on the development of greenery, environmental art and waterscape. It is a leisure place and a cultural attraction. It has good visual effects and is prone to environmental benefits. Therefore, a successful water park for investment planning, construction and management will become a water park. The main leisure and entertainment projects that drive the development of the tertiary industry in the local and surrounding areas will stimulate the development of related industries (such as real estate, restaurants, commercial streets, etc.), so that the surrounding real estate will increase in value.
