Pazogrebnevaya plate: technical characteristics, fire resistance, soundproofing, weight, photo

Pazogrebnevaya plate, the technical characteristics of which will be presented below, is intended for arrangement of interior partitions.

Comparison with other materials

These products have appeared with the aim to reduce the laboriousness of the work and the cost of laying the partitions. These statements are based on specific data. So, if you use one described product, the length of which is 66.7 cm and the height is 50 cm, then it is able to replace 14 sesquioxide silicate products, the same plate replaces 20 single red bricks (250 x 120 x 65 mm). If you make a comparison with a silicate grader, these figures will be somewhat more modest: 5 and 7 bricks, respectively, but in this case, the plates can be used to accelerate and lower the cost of work.

Assignment of gravel slabs

Partition walls are designed for installation in residential and public buildings, where the rooms have a ceiling, the height of which does not exceed 4.2 m. In view of the fact that the slab, whose technical characteristics are worth knowing before using it, has a significant lateral area And a small width, the last of which varies within 8-10 cm, on the lateral faces, to improve the stability of the masonry, the articles are provided with a "groove-comb" type joint. This design solution allows you to simultaneously increase the evenness of the product. The plate is precisely mounted on the longitudinal seam and firmly connected to a series of standing seams.

Main features of gypsum slabs

Gypsum plasterboards, whose technical characteristics are presented below, are produced using injection molding technology. The product is based on gypsum, which is produced under the G-4 or G-5 brands. Construction gypsum acts as an environmentally friendly material that perfectly passes air. This allows us to state that the partitions on the basis of the described products correspond to all sanitary and hygienic rules. In order to increase the operational and strength properties, plasticizing compounds are added to the gypsum.

Varieties of slabs in terms of moisture resistance

Pazogrebnevaya plate, the technical characteristics of which are interesting to those who plan to engage in the construction of partitions, can be moisture resistant and conventional. Each of these products is characterized by the ability to water absorption. To ensure that the plate does not absorb moisture, portland cement is added to its composition, as well as granulated blast furnace slag. And that products with low water absorption are different from the usual, a green pigment is added to their ingredients.

Pazogrebnevaya plate, the technical characteristics of which correspond to the product with a normal water absorption, can be used in buildings where the rooms are normal and low in humidity. With regard to moisture resistant boards, which are known as hydrophobized, they can be used in buildings where rooms are characterized by high humidity, while it is recommended to use SNiP II-3-79.

Main characteristics

Slabs, technical specifications, photos of which are presented in the article, must be studied before you use them in the installation of partitions. Thus, a conventional gypsum board has a density equal to 1350 kg / m³. In moisture-resistant, this parameter is equal to an indicator of 1100 kg / m³. The water absorption of an ordinary plate of gypsum is 26-32 percent. But in moisture resistant, this figure is reduced to 5 percent. If you decide to purchase a conventional gypsum-based board, you should follow the M-35 marking, whereas the moisture-resistant gypsum board is designated by the manufacturer with the M-50 marking. Be sure to consider this when choosing.

Pazogrebnevye plates, the technical characteristics of which are of interest to every master before working with them, have a certain size. So, the usual gypsum board for arrangement of partitions has the sizes equal 667 х 500 х 80 mm, that is true also for that which has qualities of the raised water resistance.

The heat-storage index is also important. If we are talking about a plate whose thickness is 80 millimeters, then such an article can be considered equivalent to a concrete wall, the last of which has a thickness equal to 400 millimeters. When settling the partitions and choosing the material for them, consumers tend to pay attention to the noise insulation factor. In a gypsum board, this parameter can vary from 34 to 40 decibels, which is very attractive for the material used to install interior partitions.

Parameters of fire resistance of plates

Pazogrebnevaya plate, technical characteristics, fire resistance which must be studied before the moment of purchase, has impressive qualities in the issue of safety with direct exposure to the flame. So, if a fire is exposed to a plate , the temperature of which is +1100 degrees Celsius, then the product will sustainably endure such loads for three hours. At the same time, the carrying capacity will not be lost. In order to reduce the weight of the masonry, it is possible to mount a hollow gypsum product, the size of which is standard and equal to 667 x 500 x 80 mm. Their weight is almost 25 percent less compared to plates, which are called full-bodied. So, the slab, technical characteristics, the weight of which is important to know before the beginning of installation works, has a mass equal to 22-24 kg, which is true for a hollow article. Whereas the full body weighs in the range of 30-32 kg.

Among other things, the plates can be distinguished by the parameters of the ridge and groove, which have different shapes. These parts of the product can be trapezoidal or rectangular. But no matter what form you choose to use a lock connection, this will not affect the strength and quality characteristics of the partitions in any way.

The main features of silicate slabs

Pazogrebnevye plates, the technical characteristics of which may be different, if it comes to another composition, in some cases have more impressive strength characteristics. So, the basis of silicate plates is water, quartz sand, as well as quicklime lime. After all the ingredients have been mixed, the composition passes through the pressing stage and enters the autoclave chamber. In it, the future slab undergoes significant temperatures and pressure, which makes it possible to obtain a calc-sand conglomerate, which is characterized by increased strength.

Silicate plates do not have an impressive water absorption index. This indicates that such products can not be used in buildings whose premises are characterized by a high level of humidity. These plates are actively used for the erection of self-supporting partitions. The weight of such a silicate slab is 15.6 kilograms, while the density is equivalent to 1870 kg / m ³ . If you make a comparison with gypsum, then the latter has a much lower density and is equal to 1570 kg / m ³ , which positively affects the quality of heat-saving and sound absorption, which consumers value very much, giving preference to these materials.

Characteristics of silicate gravel products

Pazogrebnevye plates, technical specifications, soundproofing which you now know, are very common today. If we talk about the silicate variety of such products, it has its own characteristics. So, the plates have a size equal to 500 x 250 x 70 mm, and they are produced under the brand M-150. Their water absorption index is 13.6 percent, but the density is 1870 kg / m ³ .

What do you need to know about silicate slabs before starting work?

If we compare silicate slabs with gypsum boards in terms of fire resistance, then the first few are less able to cope with the effect of fire. Their positive feature is that they will not release toxic gases during operation. In addition, they do not conduct electricity. At the base of the fastening of the silicate slab is also a paso-gable lock, the distinguishing feature of which is the ability to extinguish the sound.
