What special treatment is given to the ice used for ice carving

Ice glass is the use of engraving and drawing to make a variety of three-dimensional, transparent and exquisite patterns through chemical reactions. It can be said that the ice glass is an extension of the concave glass, but the effect of the ice glass is more obvious and three-dimensional than the concave glass. The production of ice glass has the characteristics of small investment, quick results, and enthusiastic market response.

1. Production requirements:

1 Ice Sculpture Pool: The size of the pool is determined by the size of the glass made. PVC panels are used to make the bottom of the pool and build the surrounding frame.

The lid is made of wood and plastic film, and the junction between the lid and the surrounding frame should be sealed due to the volatility of hydrofluoric acid and sulfuric acid.

2. Production personnel: Since the ice glass is completely in accordance with the artificial production and the corrosion of the glass surface with hydrofluoric acid and other substances is very dangerous, it can hurt people's ** and even bones, it is recommended to equip with alkaline neutralization equipment to solve emergencies. The volatile gas of hydrofluoric acid is toxic and corrosive, so the staff should wear protective clothing, protective boots, gloves and masks when handling acids.

3.Production efficiency: 1-2 people can produce 20-30 square meters per day.

2. Ice Sculpture Liquid Formula:

The depth and effect of corrosion depends on the strength and temperature of the acid, the quality of the glass and the immersion time. Soaking glass requires adjusting the soaking method according to different situations. Roughly, sulfuric acid) hydrofluoric acid) water) is universally applicable, and if deep corrosion is to be carried out, the concentration of hydrofluoric acid and water needs to be increased, and it is important to remember that the acid must be added to the water first, not to the acid.

Three. Production process.

1.Wash the glass.

Because there are certain inorganic substances on the surface of ordinary glass, the surface of the glass should be washed with alcohol or hot water to remove the inorganic matter before soaking in the pool, so that the glass after being soaked in acid can produce a crystal clear, smooth and flawless effect. At the same time, it can also improve the service life of the ice carving fluid.

2.Soak in glass.

The two sides of the glass are covered with a protective film to prevent acid corrosion of the other parts of the glass, and the protective film of the decorative part is removed and the glass is soaked in a pool, and the soaking time is determined by the effect required by the customer. Generally, the longer the immersion time, the stronger the corrosion effect, note (The room temperature is generally 35 degrees is the best reaction temperature.) When satisfactory results are achieved, the glass is usually removed from the pool using a plastic hook.

Ice glass is gradually occupying a place in the market with its simple production and beautiful artistic effect.

Ice sculpture is an art form that uses ice as the main material to carve. Like sculptures of other materials, ice sculptures are also divided into three types: round carving, relief carving and openwork carving. Ice sculpture is the same as sculpture of other materials, paying attention to the use of tools, surface treatment, and knife marks, but because it is colorless, transparent, and has the effect of refracting light, the carved image is not strong in three-dimensionality, and the image is not clear enough.

The ice used in the Harbin ice sculpture is cut from the river and pulled to the exhibition site, and then made on site.

It's minus 20 degrees over there, and it can't be melted at all.

As for other places, some apply glue to insulate the heat.

Ice sculpture is an art form that uses ice as the main material to carve, and belongs to plastic arts.

<> ice carving literally: it is to use ice cubes and carve them into a work in front of the stove by the carver.

Generally, the people of Harbin North also call them ice lanterns or ice and snow world.

In recent years, the Southern Ice Sculpture Exhibition has also become very popular, and it is generally done to attract popularity by destroying scenic spots or real estate as warm-up activities.

Ice sculptures are available in colored, white or transparent ice sculptures.

1.Design planning for ice sculptures. In the process of making an ice sculpture, the step is to turn a larger idea into a feasible design blueprint, which mainly includes the following process:

Carry out design planning, determine the future appearance and shape of the ice sculpture, propose specific production steps, formulate a list of purchased materials, prepare all the required production equipment, and the whole design planning is basically completed.

2.Get ice cubes for crafting. Ice cubes must be used as raw materials to make ice sculptures, which can be purchased, melted in an ice pot and injected by water pumps.

3.Processed and formed ice sculptures. Common processing and engraving tools include chainsaws, spring fiber flame cutters, drill bits, files and file knives, etc., but it should also be noted that different carving tools should be properly distributed and used according to different shapes to prevent damage to the shape of the ice sculpture.

4.Modeling of the Yi line. After the shape of the ice sculpture is made, the next step is to model the ice sculpture line, which is also a very critical step of the ice sculpture, through modeling, the shape of the ice sculpture can be retained, and the details of the ice sculpture can be expressed more delicate and three-dimensional.

5.Ice sculpture surface protection treatment. In order to prevent the surface of the ice sculpture from being melted, and at the same time to facilitate the control of hail shape, it is necessary to protect the surface of the ice sculpture, generally using mixed materials such as cement, plastic or non-coloring mortar, and coating it on the outer layer of the ice sculpture to fully complete the surface protection work.

6.Decoration and decoration to achieve ice sculptures. Decoration and decoration affect the effect of ice sculpture to a certain extent, some people can directly use the decoration of colored lanterns to put on the ice sculpture, and some people can use carving technology to decorate the ice sculpture, which requires everyone to choose flexibly according to their needs, and can also comprehensively use the decorative effect of the two.

Ice sculptures areIce sculptures are decorated with modern technology lasers to create a variety of three-dimensional or two-dimensional space image entities through carving, carving, and plastic methods.

Although the ice building was built by masonry, its final shape is still inseparable from carving. Due to the severe cold climate in Tohoku, giant ice cubes are readily available, so the volume of ice sculptures has become larger and larger, and it has become a veritable world of ice sculptures. Harbin and Urumqi are important cities to host international ice sculpture competitions.

a. There is no new substance generation in the process of ice cube making ice sculpture, which belongs to physical change B. There is new substance ammonia and other substances generated in the process of thermal decomposition of ammonium bicarbonate, which belongs to chemical change C. There is no new substance generation in the process of watermelon pressing into watermelon juice, which belongs to physical change d. In the process of separating liquid air to oxygen, only the state changes, and no new substances are generated, which belongs to physical change

Therefore, choose B

During the process of ice carving, the mass of the ice decreases, but the density of the ice remains the same

Therefore, choose D
