In today's world there are more opportunities in the industrial sector. Technological capacities allow to get acquainted with the newest material called perlite. This is a unique product that in a short time occupied a high place in the construction market.
perlite production technology is quite complex. It is made of glass-hard volcanic rock. The raw material has the ability to increase at times when a certain heating. Such a process of blistering during heat treatment, together with the addition of other materials allows to obtain heat and sound insulation raw material with excellent characteristics.
Scope
Due to the presence of high physical and technological properties, perlite insulation finds its wide application in various industries:
- energy;
- medical;
- metallurgy;
- food;
- oil refining;
- construction;
- agricultural;
The distribution of this material into fractions indicates the place of direct use of each subspecies.
Here are examples of the more common ones:
- filtroperlit has a size of 0 to 0.16 mm .;
- building in terms of perlite ranges from 0.16 to 1.25 mm .;
- Agroperlit has 1,25-5mm fraction.
Main advantages
We perlite, as another material has its own pros and cons. But despite its shortcomings, it is an integral part of any construction.
You can highlight the following advantages like perlite insulation:
- The ease which allows it to fit within any frame structure without increasing its strength.
- Resistance to a fairly abrupt temperature changes makes it suitable for outdoor use in all weather conditions. Can withstand from -220 to +900 ℃.
- Environmental safety, absence of toxicity in all operating conditions.
- Not an allergen for wildlife and people.
- Resistance to most acidic and alkaline compositions.
- Is not subject to corrosion processes.
- Due to the density produced between the particles of the material during stacking layers achieves a high level of sound insulation of the assembly. Therefore there is no need to use an extra layer of insulation of other origin.
- Absolutely not subject to deformation on exposure to high temperatures domestic level. Ideal for installation of floor heating systems in buildings.
- The average price range in comparison with the materials used for similar work.
- It is highly efficient, rational and ergonomic in its application.
It is pertinent to note is inappropriate to apply perlite in rooms with constantly high humidity more than 10% or in a humid climate stable. It is not resistant to the impact of these factors.
Working with material data, it is necessary to be aware of the fact that during active operations aluminosilicate powder allocated to him. Very small particles it can harm the human body, hitting the mucous membrane. Therefore, in the process of mechanical cutting blocks, mixing the solution you should use precautions and protect exposed areas of the body.
material variety
Only four types of insulation material. They differ among themselves not only a way of laying and characteristics.
The main types of perlite:
- Loose-fill a form, or the sand is more easily than other subspecies. Therefore applied for the insulation of walls and at the same time to facilitate the final structure of any building. Another gist of it is to eliminate the use of slit-shaped, intermediate layers, filling other voids. Suitable for fitting floors, sometimes as plastering surfaces.
- Plates. This type is most common to manufacture, since it is the most popular of perlite. The great demand due to the convenience of the form for fast erection of any size or design space. With the high rate of water absorption, therefore, are useful for in-house work. When used outside buildings, is required to be added a layer of moisture barrier material. Made by compression hydraulically. Depending on the needs of different binders are used: polymers, water glass, lime, cement, bitumen and other incongruous with it.
- Roofing species that most often called by name bitumoperlit binder used in the production. This material makes it possible to easily mount the insulating structures of different shapes due to its high flexibility. Any roof or other custom design will have a decent level of thermal conductivity. So you can use these forms of roofing in the construction of low negative readings of the thermometer. As a non-combustible, it will provide proper protection structure against fire.
- Dry mixes destination manufactured with perlite fines and cement mixture. In such a preform mass necessary to add just the right amount of water to obtain a ready-to-use mortar. Effectively used for different kinds of grout joints, cavities formed in masonry slots and similar voids. With the help of a dry mix can get a special plaster. It is applied in a layer on any surface, with ease and aligning it in parallel, increasing the insulating factor for the entire structure.
For construction purposes launched production of the three main grades of perlite:
- M75;
- M100;
- M150.
The above figures on the labeling determined coefficient of the material density. This figure is very important for the kind of future assembly work, exploitation of raw material conditions.
However, any of these characteristics allows perlite density in the solution state to be so fluid to be able to fill a tiny voids in the structure. This is one of the main advantages of this material over analogues that are useful in construction of such processes.
Wall insulation perlite
Perlite insulation is suitable for home, whose walls are made of bricks or blocks.
The solution in the form of plaster with perlite is used for lining a belt-type foundation with the basement or cellar.
Process insulating walls Sediment perlite is produced with the following features:
- Preparatory and primary work begins at the time of construction of the walls of the structure.
- More used to this type of work is the sand fraction of pearlite. Its use amount is calculated in the range of from 60 to 100 kg per cubic meters. m.
- Material is filled into the space between the walls at intervals after each laying of the wall.
- To prevent subsequent shrinking of the insulating material, produced by tapping its ramming.
Technological characteristics of perlite plaster, after application and drying, allow the possibility of finishing on top of it a variety of materials. That, undoubtedly, is very comfortable and provides additional opportunities for the developer in the selection.
The uniqueness of the insulating qualities of perlite, durability and ease of use allows it long time after installation to perform its functions.
