What is the process of FRP crafts?

1. Sample production: make 1:10 samples with foam, (not colored) ** communicate with Party A, if Party A is satisfied, enter the amplification stage, enlarge to 1:1, foam draft. Communicate with Party A again, and after Party A is satisfied, the gypsum mold will be remade.

2. Gypsum mold reproduction: After Party A passes the foam manuscript, the gypsum mold will be reproduced in sections, and the mold will be trimmed, polished and dried. Then enter the FRP reproduction process.

3. FRP reproduction.

After the gypsum mold is trimmed and dried, it is confirmed that there is no structural error, and the FRP countermeasure work is carried out.

1) Demoulding treatment, coating of demoulding wax 1-3 times.

Resin base coating, resin 2 layers coating.

3) 3-4 layers of gold pot fiberglass cloth paste.

4) After confirming that the resin is completely cured, the internal steel frame is embedded (4 8 square steel, 4 4 angle iron, 3 3 angle iron mixed to build the steel skeleton, 4 8 square steel main skeleton angle iron assisted. )

After the steel frame is built, the steel frame is treated with anti-corrosion treatment, and the car is specially anti-corrosive painted.

Fourth, mold clamping, after confirming the completion of the above operation engineering, the parts are clamped. and remove the mold. Edges are cleaned of excess material. Assemble the parts.

At this point, the FRP sculpture is basically completed, and then it is post-processing.

Post-processing includes: first polishing and wax removal, and after assembly, a large wax removal correction polishing process is carried out.

The first joint pothole putty repair.

Polishing the putty repair part again.

The second putty repair, the overall repair of putty for automobiles.

Third polishing. After sanding, spray the car primer.

The putty putty is repaired again and sanded.

The second time the primer was sprayed, and after confirming that there was no problem, the 1K white high-grade car primer was sprayed. After confirming that the primer is dry and solidified, the middle coat is sprayed with a special paint for automobiles. (Color paint) with the middle layer of paint drying, and finally spray the special varnish for automobiles (bright oil brightening, or matte varnish to remove the light) to shoot again**, and confirm with Party A, if there is no modification.

Split loading and delivery. There are technicians on site to assist in the installation.

The last process of FRP sculpture - post-processing, needs to be constantly polished, repaired, painted, can not be arbitrarily reduced process, to have very good patience and the pursuit of perfection in order to customize the perfect product.

The reason why FRP custom sculpture is so popular is because it is finely made, excellent quality, and beautiful appearance. Here is a small advertisement, Shenzhen Oudi Yafan furniture and accessories **** to hire first-class professional design masters at home and abroad to design products for us, in line with integrity first, quality first.

As long as it is said that there is not much difference between FRP and FRP, the difference is just in a lining word, and it is clear what the lining means.

FRP products generally have the following processes.

1. Hand lay-up production method; 2. Jet molding method; 3. Fiber winding process method; 4. Compression molding process and molding compound molding process; 5. Pultrusion molding method.

Each technology has its own characteristics. When choosing and determining what kind of process method to use, the production enterprise needs to consider comprehensively according to the basic situation of the enterprise and the situation of the production products, such as the batch of production products and their quality requirements, as well as the technical foundation and production capital of the enterprise.

You can go to the Hangzhou Zhonghuan Chemical Equipment **** webpage to see the common questions, there is a detailed introduction there.

FRP products refer to finished products processed with FRP as raw materials. It is a new type of composite material developed in the early 20th century, which has many advantages such as light weight, high strength, anti-corrosion, heat preservation, insulation, sound insulation and so on. Because its strength is equivalent to steel, and contains glass components, it also has the color, shape, corrosion resistance, electrical insulation, heat insulation and other properties of glass, and is widely used in acid, alkali, salt, solvent and other working environments, showing good corrosion resistance.

Chemically tempered glass is mainly based on glass with a thickness of less than 3mm, and chemically tempered glass is to improve the strength of the glass by changing the chemical composition of the surface of the glass, and it is generally tempered by ion exchange method. The method is to immerse the silicate glass containing alkali metal ions into the lithium (Li) salt in the molten state, so that the Na or K ions on the surface of the glass are exchanged with the Li ions, and the Li ion exchange layer is formed on the surface, because the expansion coefficient of Li is less than the Na and K ions, so that the outer layer shrinks less and the inner layer shrinks more in the cooling process, when cooled to room temperature, the glass is also in the state of inner layer tension and outer layer compression, and its effect is similar to physical tempered glass.

White sheet finished product - QC inspection - cleaning treatment - chemical toughening --- thermal insulation and cooling - cleaning and drying - packaging. Due to the slow exchange rate of potassium and sodium ions, the exchange time varies from 1 hour to 8 hours in order to make the glass have a large stress value and the thickness of the stress layer that meets the requirements of use.

Advantages of chemically tempered glass:

Chemical tempered glass does not have a high-temperature process above the transition humidity, so there will be no warping like physical tempered glass, and the surface flatness is the same as that of the original glass, and at the same time, the strength and temperature resistance to changes have been improved, and can be appropriately cut.

Chemical tempered glass has high strength, and its compressive strength can reach more than 125MPa, which is 4 5 times larger than ordinary glass; The impact strength is also very high, and when measured by the steel ball method, the steel ball falls from a height and the glass remains intact. The elasticity of chemical tempered glass is much greater than that of ordinary glass, a piece of 1200mm 350mm 6mm tempered glass, after being stressed, can occur up to 100mm bending deflection, when the external force is removed, it can still return to its original state, while ordinary glass bending deformation can only have a few millimeters. Good thermal stability, not easy to burst when subjected to quenching and rapid heating is another feature of chemically tempered glass.

This is because the compressive stress of chemically tempered glass can offset part of the tensile stress caused by quenching and heating. Chemically tempered glass is resistant to thermal shock, with a maximum safe operating temperature of 288 and can withstand a temperature difference of 204 °C.

Chemical tempered glass is suitable for use in the following construction occasions: there are requirements for reducing dead weight, and at the same time there are certain requirements for impact strength, bending strength and cold and thermal shock resistance, such as windows and ceilings of agricultural greenhouses, doors and windows of mobile houses, etc.

Process.

Cold processing - cleaning - loading - primary preheating - ion exchange - secondary preheating - cooling - pure water cleaning - packaging.

Each process is very rigorous, a complete production line investment needs to invest about 10 million, high-quality products in three aspects, advanced and stable tempering furnace + excellent ion formula + perfect supporting measures.

The production process of FRP is as follows:

1. Hand lay-up production method: Hand lay-up molding process, also known as contact molding, is the earliest and most commonly used and widely used molding method in the production of resin matrix composites. Hand lay-up molding process is a process method that uses a resin mixture with curing agent as the matrix, glass fiber and its fabric as the reinforcing material, and combines it with manual laying on the mold coated with release agent to bond the two together to manufacture FRP products.

The matrix resin is usually unsaturated polyester resin or epoxy resin, and the reinforcing material is usually alkali-free or medium-alkali glass fiber and its fabric. In the lay-up molding process, the use of machinery and equipment is less, it is suitable for the production of multi-variety, small batch products, and is not limited by the type and shape of the product.

2. Jet molding method: a method of manual lamination with the help of a jetting machine. This method has the characteristics of high efficiency and low cost, and has a tendency to gradually replace the traditional hand lay-up process.

The integrity of the product is strong, there is no lap seam, and the geometric size of the product is basically not limited, the molding process is not complicated, and the material formula can maintain a certain accuracy. The disadvantage lies in the fact that the quality of the product depends to a large extent on the production skills of the operator. In addition, the pollution caused by injection is generally greater than that of other process methods.

3. Fiber winding process method: The continuous fiber impregnated with resin is wound to the core mold according to a certain rule, and the lamination is cured to the required thickness and then demolded, which is a finished product. The characteristics of this method are that the winding law of the fiber can be designed according to the stress of the product, so that it can give full play to the tensile strength of the fiber, and it is easy to realize mechanization and automation, and the product quality is relatively stable.

It can be successfully applied to the production of FRP pipes, storage tanks, gas cylinders, fan blades, high-rise jumping poles, wire poles, badminton rackets and other products.

4. Molding process and molding plastic molding process: The pressing process and equipment conditions are basically the same, the former uses dipping tape as the molding material, and the latter uses sheet, agglomerate and bulk molding material, first placing a certain amount of molding material in the metal mold, and then forming the required FRP products at a certain temperature and pressure. This production molding method, the size of the product produced is accurate, the surface is smooth, the production efficiency can be formed at one time, and the product quality is relatively stable, and it is suitable for making various small FRP products in large quantities.

Its disadvantage is that the design and manufacture of the mold are more complex, the initial investment in production is higher, and the limitation of the workpiece by the equipment is more prominent.

5. Pultrusion molding method: under the traction of the traction device, the fiber reinforced material impregnated with resin is first preformed in the mold, and then cured and formed by heating to make FRP profiles, and finally cut into FRP products of the required length.

At present, the domestic main use of hand lay-up production method and fiber winding process method to produce FRP products.

The process of making FRP: FRP acid mist purification tower process.

Process flow: First, the FRP acid mist neutralization tower needs to have the design of the packing layer, the packing layer has its suitable height, 50 mm plastic ring or a hollow sphere with many faces, so that the effect is that the lye in the tower can increase the contact area with the acid mist, and the long-term contact naturally increases the absorption efficiency, and the exhaust gas generated after the chemical reaction is discharged from the top wind of the purification tower.

Second, the lye pump has a built-in fluoroplastic or plastic-flavored centrifugal pump, which is designed to be corrosion-resistant, and the operation effect is very good, and the equipment is also very convenient when it is regularly inspected or repaired;

Third, exhaust is more important, and the selected exhaust fan A-type transmission is equipped with a fan made of polyester polypropylene.

Fourth, there are ladders and sewage pipes that can go up and down next to the lye tank, which is much easier to maintain.

The use of FRP acid mist purification tower is obvious, it is necessary for the acid mist purification link in the industrial field, and the purification tower made of FRP has high efficiency, low cost, durability, energy saving and environmental protection.

FRP production requires the use of fiberglass and resin. The resin is in a liquid state, and after a period of time when peroxide is added, it reacts to become solid. Glass fiber is a lot of very fine glass filament, the glass fiber is infiltrated into the resin, and after the resin is cured, it becomes glass fiberglass.

Because the strength of fiberglass is high, the strength of fiberglass is also high.

There are so many processes for FRP, which one do you want?

FRP products are widely used and can be an ideal material to replace some metals and plastics, which can not only save the consumption of metal resources, but also reduce plastic pollution caused by non-degradation. In the vast countryside, the rain cover made of FRP is comparable to plastic in terms of performance, and the service life is greatly increased.

FRP products are a kind of composite materials that have developed rapidly in the past 50 years. 70% of the production of fiberglass is used to make fiberglass. FRP has a high hardness and is much lighter than steel.

It is used as a fuel tank and pipe in jet aircraft, which can reduce the weight of the aircraft. FRP products are easy to process, stainless and rotten, and do not need paint. China has widely used FRP to manufacture various small motorboats, lifeboats, yachts, and automobile manufacturing, saving a lot of steel.

Because FRP products are a kind of composite materials, the adaptability of its properties is very wide, so its market development prospects are very broad.
