Color collocation of teachers' decoration in Hainan decorative classroom

Article 1: There must be no more than three spatial color schemes, among which white and black are not counted as colors.

Rule 2: Gold and silver can match any color. Gold excludes yellow, and silver excludes gray and white.

Article 3: The best gray scale for home color matching without designer's guidance is: shallow wall, medium floor and deep furniture.

Article 4: Don't use warm colors in the kitchen, except yellow.

Article 5: Don't kill dark green floor tiles.

Article 6: Even if no one threatens to kill you, you must never put materials with different materials but the same color together. no

Then, you will have a fifty-fifty chance to make a mistake!

Article 7: If you want to create a bright and modern home taste, then don't choose anything printed with big flowers and small flowers (except plants).

Try to use simple design.

Article 8: The ceiling must be lighter or the same color as the wall. When the color of the wall is dark, the ceiling must be used.

Use light colors. The ceiling can only be white or the same color as the wall.

Article 9: If the space is not closed and used for wearing, you must use the same color scheme. Different accessories can be used in different enclosed spaces.

Color scheme.

Article 10: If this "law" is used outside the family, it may be 90% wrong!

Explanation:

What is gray scale? It's simple. Just print out the color you want to use on the black-and-white copier and compare it. Whether the weather is warm or not.

This is a cool color system, it must have its gray scale.

What is plain color? It's pure monochrome.

What is color system? Close to the same color

In general interior design, the use of three colors will be restricted. Of course, this is not absolute, because of professionalism.

Interior designers are familiar with the deeper color relationship, and may use more than three colors, but generally only one or two.

Limit the definition of three colors:

1. Three colors are in the same relatively closed space, including ceiling, wall, floor and furniture. The living room and master room can have

Each system has a different color scheme, but if the living room and dining room are connected together, they are regarded as the same space.

2. White, black, gray, gold and silver are not within the three-color limit. But gold and silver are generally different.

Only one of gold or silver can be used in the same space.

3. The pattern category is subject to its color. For example, a piece of cloth has many colors, because colors have many relationships, so professionally,

Subject to the main display color. The method is to squint at its main color. But if a big pattern is independent,

If the color block is large, it should also be regarded as a color.

Decoration of water supply and drainage pipes

For home decoration, water supply and drainage pipes mainly talk about water supply pipes. Now the pipeline materials on the market are colorful,

Users are often confused. So what kinds are there and which ones are suitable for use? Below, we will introduce it in detail.

Analysis.

I. Type of pipeline

1, galvanized iron pipe

20 1 galvanized iron pipe is one of the most widely used materials at present. Due to the corrosion of galvanized iron pipes, the content of heavy metals in water is too high, which affects the water quality.

For the sake of human health, government departments in many developed countries and regions have begun to explicitly prohibit the use of galvanized iron pipes. At present, China is working hard.

Phase out this type of pipeline.

2. Copper tube

A traditional but expensive pipeline material is durable and convenient to construct. In many imported bathroom products,

Copper tube is the first choice. Price is the main reason affecting its use, and copper corrosion is also a factor.

3, stainless steel tube

Stainless steel pipe is a durable pipe. However, its price is higher, the construction technology is higher, and it is better than its material.

The strength is hard and the field processing is difficult. Therefore, the probability of being selected in the decoration project is low.

4. Aluminum-plastic composite pipe

Aluminum-plastic composite pipe is a popular pipe in the market at present. Because of its light weight, durability and convenient construction, it can be bent.

Sex is more suitable for home improvement. Its main disadvantage is that when it is used as a hot water pipe, the pipe will be deformed due to long-term thermal expansion and cold contraction.

The wall is misaligned, resulting in water leakage.

5, stainless steel composite pipe

Stainless steel composite pipe and aluminum-plastic composite pipe are similar in structure and performance. Similarly, due to

The strength of steel and construction technology are still a problem.

6. PVC pipe

PVC plastic pipe is a kind of modern synthetic material pipe. But in recent years, the scientific and technological circles have found that PVC can become more

Phthalein is a kind of soft chemical additive, which has a great influence on the kidneys, liver and testicles in human body, leading to cancer, kidney damage and harm to human body.

It can recreate the system and affect development. Generally speaking, it is rare because its strength is far from meeting the pressure requirements of water pipes.

Used for water pipes. In most cases, PVC pipes are suitable for electric wires and sewage pipes.

7. Polypropylene pipe

PP (polypropylene) pipes are divided into several types, namely:

1 and PP-B (block * * * polypropylene) are also commonly known as hot-melt pipes, because welding technology is used in construction. Because it is non-toxic and qualitative

It is light in weight, pressure-resistant and corrosion-resistant, and is becoming a popular material, but it is seldom used in decoration engineering at present.

It is said that this material is not only suitable for cold water pipes, but also for hot water pipes and even pure drinking water pipes.

2, PP-C (modified polypropylene) pipe, the performance is basically the same as above.

2, PP-R (random polypropylene) pipe, the performance is basically the same as above.

The physical characteristics of PP-C(B) and PP-R are basically similar, and the scope of application is basically the same, so they can be used interchangeably in engineering. Major differences

The low temperature brittleness resistance of PP-C(B) is better than that of PP-R; The high temperature resistance of PP-R material is better than that of PP-C(B). In practical application,

When the temperature of liquid medium is ≤5℃, PP-C(B) pipe is preferred; When the temperature of liquid medium is ≥65℃, PP-R is preferred.

Tube; When the temperature of liquid medium is between 5℃ and 65℃, the properties of PP-C(B) and PP-R are basically the same.

Second, the pipeline installation matters needing attention

Waterproofing is often more important than any other topic in decoration. What should be paid attention to in the process of pipeline installation and use?

And then what?

1, pipe installation must find a professional mechanic. No matter how luxurious and upscale your decoration is, if you don't want to spend money on it.

Not worth it. Often pipes suddenly crack or leak, which will cause the price of water pipes to be dozens, hundreds or even thousands of times.

Loss.

2. After installation, pressure test must be carried out. Pressurization test is generally carried out under the condition of 1.5 times of water pressure, and there should be no

There is water leakage in 202.

3, under the condition of no pressure test method:

1) Close the main water valve. (that is, the water pipe switch in front of the water meter)

2) Turn on the faucet in the room for 20 minutes, and then turn off all the faucets after ensuring that there is no dripping.

3) Turn off the water inlet switch of toilet water tank, washing machine and other equipment with water storage function.

3) Open the main water valve.

4) After opening the main valve for 20 minutes, check whether the water meter moves, including moving slowly.

If there is any movement, it is leaking. If you don't move, you'll be fine.

4. In daily use, if the following conditions are found, check the relevant pipelines as soon as possible:

1) The surface of the wall paint is moldy and blistered.

2) The baseboard or wooden floor is black and bubbles appear on the surface.

Introduction and comparison of all kinds of ceramic tiles

First, glazed tiles

1, as the name implies, glazed tiles are tiles with glazed surfaces. According to the different raw materials, it can be divided into two types:

1) ceramic glazed tiles, that is, fired with clay, have high water absorption and relatively low strength. Its main feature is the back color.

It is red.

2) Porcelain glazed tiles, that is, porcelain clay fired, have low water absorption and relatively high strength. Its main feature is the back color.

It's grayish white.

It should be noted that the comparison of water absorption and strength mentioned above is relative. Now there are some ceramic glazed tiles that absorb water.

Rate and strength are better than porcelain glazed tiles.

2, glazed tile glaze according to the different luster, also can be divided into the following two kinds:

1) bright glazed tile. Suitable for creating a "clean" effect.

2) Matte glazed tiles. Suitable for creating a "fashionable" effect.

3. Frequently asked questions

Glazed brick is the most common brick in decoration. Because of its rich color patterns and strong antifouling ability, it is widely used in walls and buildings.

On the ground, there are two common quality problems:

1) cracking

The root cause of cracking is that the stress between the glaze and the blank exceeds the difference of thermal expansion coefficient between the glaze and the blank. When the glaze is hotter than the blank.

When the expansion coefficient is large, the shrinkage of the glaze is greater than that of the green body when it is cooled, and the glaze will be subjected to tensile stress. When the tensile stress is greater than the stress that the glaze layer can bear,

When the ultimate strength is reached, cracks will appear.

2) Reverse osmosis

No matter what kind of brick, water absorption is natural, but when the density of the green body is too loose, it is not just a problem of water absorption, but

The problem of cement infiltration. That is, cement sewage will penetrate into the surface.

4. General specifications

Square glazed tiles are 152× 152mm and 200×200mm, and rectangular glazed tiles are 152×200mm and 200×300mm.

By analogy, the commonly used glazed tiles are 5 mm and 6 mm thick. ..

Second, the whole brick

The surface of the brick is not glazed, and the material and color of both sides are the same, hence the name.

Brick 203 is a kind of wear-resistant brick. Although there are still varieties of infiltrated bricks, relatively speaking,

Its color is not as good as glazed tile. Because the current interior design is more and more inclined to plain design, so

Bricks are becoming more and more fashionable and widely used in halls, aisles and outdoor walkways.

The ground of repair works is generally less used for walls, and anti-slip bricks mostly belong to whole-body bricks.

Common specifications of bricks are 300x300mm, 400x400mm, 500x500mm, 600x600mm,

800x800mm and so on.

Third, polished tiles.

Polished brick is a kind of bright brick with polished surface. Polished brick is a kind of integral brick. mutually

For the rough plane of the whole brick, the polished brick will be much smoother. Polished tiles are hard and wear-resistant, suitable for cleaning toilets.

It is used in most indoor spaces outside the kitchen and indoor environment. Based on the application of infiltration technology, polished tiles can be made into various kinds.

Plant imitation stone and wood effects.

Perhaps it is the carelessness of the industry, perhaps it is the intention of the industry, but the polished brick has left a fatal shortcoming: it is easy to get dirty. This is polishing

It is caused by concave-convex pores left by bricks during polishing. These pores will hide evil and shelter evil, so that polished tiles will change color when it comes to pollution, and even some.

Tea poured on polished tiles is powerless.

Maybe everyone is aware of this. Later, some polished tiles with good quality were added with an antifouling layer when they left the factory, but this layer was antifouling.

Layer makes polished brick lose the effect of whole brick. If you want to continue to connect the whole body, you have to continue to brush the antifouling layer. And the decoration circle.

Waxing before construction to prevent scaling.

The common planes of polished tiles are 400x400mm, 500x500mm, 600x600mm, 800x800mm, 900x900mm,

1000 x 1000 mm.

Fourth, vitrified brick.

In order to solve the problem that polished tiles are easy to get dirty, another variety called vitrified tiles appeared on the market. Vitrified bricks are actually

Tiles. Its surface is smooth but does not need polishing, so there is no problem of polishing pores.

Vitrified brick is a kind of reinforced polished brick fired at high temperature. The texture is harder and more wear-resistant than polished tiles. There is no doubt,

Its price is also higher.

Vitrified bricks are mainly floor tiles, and the common schemes are 400x400mm, 500x500mm, 600x600mm and 800 x 800 mm.

900x900mm, 1000 x 1000 mm.

Verb (abbreviation of verb) mosaic

Mosaic is a special kind of brick, which is usually made up of dozens of small bricks.

Forming a relatively large brick. It is small and exquisite, rich in colors, and widely used in small indoor areas.

Walls and large and small walls and floors outside rooms. It is mainly divided into:

1, ceramic mosaic. It is the most traditional mosaic, famous for its small size, but monotonous and low-level.

2. Marble mosaic. It is a mosaic variety developed in the middle period, which is rich and colorful, but it has poor acid and alkali resistance and waterproof performance.

Not good, so the market response is not very good.

3. Glass mosaic. Colored glass brings vitality to the mosaic. According to the variety of glass, it is divided into

Various small varieties:

1) fused glass mosaic. With silicate as the main raw material, it is formed by high temperature melting, opaque or translucent.

A glass mosaic containing a small amount of bubbles and unmelted particles.

2) Sintered glass mosaic. Glass powder is used as the main raw material, and a proper amount of binder is added to press it into a green body with a certain size;

Glass mosaic sintered at a certain temperature.

2043) Venus glass mosaic. It contains a small amount of bubbles and a certain amount of metal crystal particles, and there is a glass horse that obviously flashes when exposed to light.

Sykes.

4. General specifications

The common specifications of mosaics are 20×20mm, 25×25mm and 30×30mm, and the thickness ranges from 4mm to 4.3mm in turn.

There are all kinds of other brick names on the market, but no matter how messy they are called, they are basically.

Can be classified as one of the above varieties.

Six, the following introduces the choice of brick.

The choice of tiles, in addition to your favorite color, must be decided with a scientific attitude.

First, take any four tiles out of the box and put them on the flat ground. Then compare, four.

Are the bricks flat and consistent? See if the diagonal of the tile is embedded. Then use your palm

Tap the surface of the tile and listen to the sound: a good tile has a low sound; Bad tiles sound bright,

And there is a clear echo. Of course, judging from the sound is relative. But the first comparison is impossible.

The biggest difference between domestic and imported products is the consistency of ceramic tile product specifications.

Beware of five traps in home improvement

The reporter learned from the relevant departments that last year's home improvement complaints did not decrease compared with the year before, and there were still some individuals in the decoration market.

The phenomenon of irregular management and cheating consumers. According to industry experts, illegal decoration companies have "dug" a "trap" for consumers.

More and more hidden, while we call for strengthening management and standardizing the order of the home improvement market, consumers who are ready to decorate have to be careful.

Be careful. The reporter asked the experts to reveal the "decoration trap" one by one, and you will no longer be fooled if you see through the deception.

"Trap 1": Add items after the start of low-bid bidding business.

Some decoration companies offer lower quotations than other companies when customers ask for quotations to attract consumers to sign the bill. The most common

The trick is to steal projects. They took advantage of consumers' ignorance of decoration and cut off some projects first, resulting in a lower total offer than other companies.

The illusion of our offer. In the process of construction, deleted projects will be added to increase funds. After completion, it is often at the time of final accounts.

It is 10% to 20% higher than the budget, even higher than the quotation of regular companies. The management level of companies that usually use this deception is not

High, design and construction ability is also questionable. It is easy for consumers to fall into the "low price trap" and miss better designers and decorations.

Company.

How to deal with it: the quotation of home improvement includes: labor cost, material cost, construction cost, management fee, tax, reasonable profit, etc.

Is necessary. When reading the budget table in the contract, you should carefully check whether there are any omissions, and don't trust the low quotation.

"Trap 2": Designers deliberately add items just to get more commissions.

Some designers deliberately increase decoration projects in order to get more commissions from the company after taking orders, regardless of the actual situation of consumers' homes.

Purpose: If partitions are added where partitions are not needed, but ceilings are needed where ceilings are not needed, and so on. After some "design",

The decoration quotation is obviously higher than the original budget. Of course, at this time, the designer's commission will also increase significantly.

How to do it: To deal with this trap, consumers must find out their life needs. For the high cost of designers,

For projects with no practical value and decorative effect, we should stick to our own opinions and don't have to spend more commission on designers.

Money.

"Trap 3": Material procurement is shoddy.

In the decoration of contracted materials, some construction teams resort to deceit when purchasing materials, and some are shoddy.

Use low-priced defective products as genuine products and so on. According to industry insiders, taking an 80-square-meter house as an example, a 30,000-yuan project can

Save more than 3000 yuan. If you buy unqualified inferior cement, you can save about 100 yuan to 200 yuan; Buy unqualified and inferior tiles
