Specifications

Gypsum has a number of technical indicators with which you should read before choosing the material for further work. Gypsum has a fine-grained structure, its bulk density varies from 2.60 to 2.76 g / cm3. If we talk about a loose variety, the indicator reaches 850-1150 kg / m3, in a compacted form, the density is even higher (up to 1455 kg per m3).

It is important to note that the material is manufactured according to GOST, therefore meets all the requirements and standards. One of the advantages of production is the rapid hardening and fight, the solution will easily dry and after four minutes after the preparation grasps, frozen in half an hour. This means that the finished material must be used immediately and completely. To slow down this process, specialists mix gypsum with adhesive substances. The specific weight is equal to the volume of material.

Gypsum solution can be heated, while properties are saved. Items from this material have fire resistance, and even if the temperature exceeds the critical indicator, the destruction will occur after 6-8 hours. As for strength, it should not be noted that this indicator in compression is 4-6 MPa, the high-strength view reaches 40 MPa, the dried samples can be stronger three times. The material does not heat the material, it can be easily dissolved in water, but with each time heating solubility decreases.

As you can see, the properties of the construction mixture are amazing, which is why it is so often used in different spheres.

Translucent plaster is fine-grained, so this option is great for filling the seams and plates connections. The material in liquid form is prepared from the powder and water, so the density can be chosen independently, based on the scope of application. Moisture-resistant plaster It turns out as a result of processing raw materials according to special technology, to improve product properties, add bard.

Gypsum is a non-combustible material, but if we are talking about sheets, this characteristic is not applicable. To impart a fire-resistant, it is better to use a puzzle mixture. High levels of plasticity possesses architectural View, there are no toxic components.

Many designers choose this material, as it is convenient and easy to work with it.

Marking

There are different grades of gypsum on the market, this indicator is always indicated on packs in the form of letters A, B, in. It is necessary to understand this to choose the most suitable material for work, given all properties and characteristics, because the composition can be quick, normal and slowly hard. It should be noted that Manufacturers share products for powder grinding degree – rough, medium and thin. The first option is denoted by the Roman number L, respectively, the second – LL, and the third – LLL.

The more high-quality surface will be parties made of thin grinding powder. Classification is carried out in strength, so in the market you can find about 12 varieties, they may look like this – M-13, Mr., Mr. and T. D. The figure indicates strength to compression, is measured in megapascals. The bags indicate the marking that can be decrypted independently to determine the degree of strength, the frost time and the type of grinding.

Additional materials

The composition of the gypsum includes such a fragile component as calcium, so it will not be possible to do without impurities and additives. At the factories, impregnations are used to fill the surfaces of the products, only after that you can apply paint. The role of impregnating material is the natural olive, but it can easily change the liquid glass or ordinary PVA glue. It is extremely important to wait for drying and only to cover the material with a coloring substance or varnish. Another addition is a plasticizer, thanks to which you can change the lifetime of the solution and even check the fluidity.

To reduce water absorption, use a hydrophobizer, while it retains vapor permeability, which is important. Condensate will appear on the surface of the gypsum product when changing the temperature. Lucky are facing material for processing gypsum products, they close the pores to reduce the absorbent property of the gypsum. The composition deeply penetrates into all cracks, as a result of which a durable thin film with good adhesion is formed.

Since the gypsum quickly freezes, sometimes you have to resort to additives that would slow down this process, especially when it comes to large-scale work. Sodium tartrates or sodium citrate are used as this substance. Sometimes experts are added to a solution of citric acid or the Dextrin preparation.

How to work with plaster?

Before you begin to knead the gypsum powder, it is necessary to calculate the proportions, given the amount of material that required. During the hardening, the amount of solution will increase slightly, heat will be distinguished, due to this, during repair and construction work, the material will fill all the excavations and cracks, along with this repeat the internal volume of the form, if you pour it into special containers for the manufacture of decorations and parts.

To mix dry mix evenly, you can use a stainless steel tool or wood. If we are talking about a large volume, the electric drill with a special nozzle will help. You can increase strength to various additives that mentioned above. After the product from the gypsum is fully prepared, it is recommended to impregnate with varnish to eliminate the porosity.

If you want to make a form for wax, bronze or plexiglass, the best option than plaster is not found. You can pour out the form yourself, this is a quick and simple process. To do this, you will need a prepared box or a container in which the solution must be poured so that it covers the thin layer of the entire inside. After frozen, the surface is processed by a lubricant material, poured with a solution of up to half and is left to harden. In this way, the lower part is created, after that you can do the top. In the gypsum you can add different components to improve its properties, it is precisely one of the reasons for such widespread use.
