What problems will be encountered in the process of making stainless steel sculptures? The process of making stainless steel sculptures is divided into many steps:

1, determine the sculpture effect and material according to customer requirements and site characteristics,

2, making a small draft,

3, expand the scale,

4. Cutting, argon arc welding and forging the stainless steel plate to achieve no obvious weld, smooth lines and smooth surface.

5. Polishing the sculpture to make its texture natural,

6, surface coloring,

7. Decompose and package, and finally go to the site for overall assembly and installation and post-processing.

In so many processes, beating of stainless steel plate is the most difficult one. In this step, the construction personnel need to beat the contrast steel plate repeatedly until the small steel plate has a certain degree of bending, which is completely consistent with the FRP model. This step obviously requires high skills of workers, and it is also the most challenging step in the production of stainless steel sculptures.

The simplest method of making FRP sculpture: first turn over the plaster mold, then turn over the FRP.

FRP needs talcum powder, catalyst (purple material), curing agent (white material), resin (196, 19 1) and glass fiber cloth.

Methods: Talcum powder and resin 1: 1 were mixed evenly, then 1% catalyst (about mineral water bottle cap) was added, and then the same amount of curing agent was added. Stir well. Brush a layer of glass fiber reinforced plastic and spread a layer of glass fiber cloth. Generally, three or four floors are enough.

Production technology of stainless steel sculpture 1, making clay sculpture.

2. Enlarge the manuscript in equal proportion.

3. Turn the mud manuscript into a hard mold.

4. Forged into a stainless steel sculpture according to the model.

5. Grind and polish the sculpture for many times.

6, stainless steel sculpture surface spraying fluorocarbon paint or car paint.

We specialize in making large stainless steel sculptures.

The production process of sculpture The production steps of sculpture:

Step 1: Preparation and screening of natural special clay, spraying water for more than 48 hours (low temperature for more than 3 days in winter) to wake up the mud. The sculpture steel bar modeling skeleton is welded by round carving, and a cross-shaped wooden stick mud supporting device is wound on the skeleton. The density depends on the actual situation, and the pulp is not dropped regionally after pouring. The metal mesh laid in the big gap on the sculpture skeleton can reduce the amount of mud, reduce the total weight, ensure that the sculpture does not collapse, and avoid collapse, scrap and rework, while the concept is safe. In case of relief, it is necessary to lay the blockboard floor, and nail the board every 15 cm. Half nail, the other half exposed, convenient to hang mud. In addition, it is convenient to hang mud by winding fine iron wire vertically and horizontally on the nail. Other details and procedures are outlined.

Step 2: Cover the sculpture with mud. When the mud is finished, just pound it with a mallet and make up the air raid between the mud. After all the mud, the big shape is constantly adjusted. Modeling is not allowed. You need to rework your bones to rest until you are satisfied. The above must be done by professional sculptors. From this stage on, the sculpture must be sprayed with water frequently to prevent cracking, and it should be covered with plastic film to moisturize on public holidays until the sculpture mold is completed. Other details and procedures are outlined.

Part III: Molding, completed by professional sculptors. In the process of shaping, the sculptor sprays water at any time to shape at any time, and the specific details of other processes are brief.

Step 4: After the sculpture is completed on a large scale, notify Party A to review the sculpture on a large scale and put forward opinions or modifications. Continue to refine and adjust the details to perfection. After all modeling is completed, push the clay sculpture as a whole and push the light with a scraper. Other details and procedures are outlined.

Step 5: enter the turning stage, cut the block mold with slices on the clay sculpture, and then spray soapy water as isolation protection. Professional copying technicians mix gypsum slurry on the cover of the sculpture, and the specific water ratio of the outer layer and the inner layer of gypsum slurry is mastered and completed by professionals. After the gypsum hardens and dries, demoulding begins. Before demoulding, the fixture should be fixed on the pad and made of gypsum numbness pile. Other details and procedures are outlined.

Step 6: After demoulding, remove the residual mud on the block mold, and then carefully repair and polish the gypsum mold. And then polished with a metal copper mesh. Other details and procedures are outlined.

Part VII: Add FRP, prepare resin, add catalyst curing agent, filler and developer, and pay special attention to the safety of chemical solvents to prevent fire. The first layer of resin sizing, the second layer of resin and glass fiber cloth sizing together, generally need three to five layers of sizing process. Select the thickness according to the sculpture. Super-large sculptures need more than 4 floors, and the thickness varies from 0.5 to 2 cm according to the size of the sculpture. Other details, processes and technologies are not detailed here. The process in this paper is only a rough process.

Step 8: Assemble the split-type FRP module, and the specific assembling technology and process are simple. After the splicing is completed, the gap should be leveled and reinforced, and the skeleton of permanent steel bar support system should be established inside. Finally, grinding, rough grinding and fine grinding with different sandpaper models. Most of them must be done by hand. Machine grinding can't be round and natural, and it is difficult to be completely seamless. It must be polished by hand with sandpaper. Other details and procedures are outlined.

Step 9: color, apply background color, color, and apply external protective coating. Concrete and simple. If you need to cast copper and bronze sculptures, it is only suitable for the background color and smooth paint layer on the outside. Other details and procedures are outlined.

What are the commonly used drying methods in the process of pharmaceutical preparation? Drying is the process of removing water from various materials. Materials can be solid, liquid or gas, and solids can be divided into bulk materials, fiber materials, granular materials and fine powder materials. , and water is generally water in the material, but also other solvents. Here, water is an object. There are three drying methods for drying equipment: (1) mechanical dehydration.

Mechanical dehydration is to squeeze out a part of water by pressing the material. Commonly used methods include squeezing, settling, filtering and centrifugal separation. Mechanical dehydration can only remove part of the free water in the material, and the combined water remains in the material. Therefore, the water content of the material after mechanical dehydration is still very high, generally 40 ~ 60%. But mechanical dehydration is the most economical method. (2) heating and drying method.

That is, we often say that drying uses heat energy to heat materials and evaporate water in materials. It takes a certain amount of heat energy to remove water from materials. Usually, air is used to dry the material, which is heated in advance and sent to the dryer to transfer heat to the material. The material vaporizes the water in the material to form water vapor, which is taken out of the dryer with the air. After heating and drying the material, it can remove the combined water in the material to achieve the required moisture content of the product or raw material. (3) Chemical dehumidification.

Moisture absorbent is used to remove a small amount of water in gases, liquids and solid substances. Because of its limited dehumidification ability, hygroscopic agent is only used to remove a small amount of water in materials, so it is rarely used in production.

In the actual production process, for materials with high humidity, mechanical dehydration is generally used to remove as much free water as possible, and then other drying methods are used for drying.

What are the common aging methods in mechanical manufacturing? In order to stabilize the efficiency of materials, the aging method is generally adopted. Aging is divided into natural aging, that is, putting the parts blank in the open air to let it be exposed to the wind and the sun, and then soaking the parts in seawater. The most commonly used method is artificial aging, that is, the parts are put into a heat treatment furnace and then naturally cooled.

The production process of sandstone sculpture

The color of the sand is too dark and not delicate enough. It is impossible to change the dark color of sandstone into light color.

Stir with resin, curing agent, catalyst and quartz sand, and preferably add a little heavy calcium carbonate to enhance the viscosity. Generally, it is pressed tightly by hand in the mold. If it is big, stick a fiber cloth on the back.

Explain the causes of foam formation during fermentation, and what are the commonly used defoaming methods, indicating that the most commonly used defoaming principle is to add defoaming agent for fermentation, and the principle is not clear.

The production of foam box The production process of video foam box is made according to the requirements of customers. Different sizes, same price. The weight and density are also different. The point is that the price also depends on the quantity of your order. Foam itself is not expensive. Size is not the only factor that determines the price.
