Minerals, which have in their composition of the liquid, strongly heated until complete evaporation of water from them. Moisture turns to steam, the allocation of which the material swells. Formed as a result of the material has good mnogoporistuyu structure, as a result of filling the pores and voids with air. This material has excellent thermal insulation.
Protective material perlite is produced by crushing rock of volcanic origin. After heating up to 10000 degrees Celsius resulting crumb swells, forming a rounded grains having a diameter of about seven millimeters. Perlite is perfect as a filler in the preparation of heat-insulating layers of plaster. Also good, he established himself as a bulk thermal insulation material.
There are certain features in the insulation of these protective material sloping roofs. By moving to a special hose blower perlite was loaded into mezhstropilnye intervals. Likewise insulate the space between dvuhskorlupovymi stone shells. Perlite is a specially pre-treated water-repellent composition.
Protective material perlite are often used to create the base of floating concrete monolithic floors. With the help of other materials obtained by the base align and stack on top of the fibrous slab. Fibreboard or laid across the surface of the floor or on a scheduled pre-planned segments. To obtain high-quality sound insulation cover is made of soundproof panels. To ensure high quality load floor is used bitumizirovanny perlite. Perlite grains are glued to the solid, has great strength of the layer that is resistant to heavy loads. Do not forget about such an important moment, as shrinkage. Therefore, dumping height created by the layer should be higher by 10-20% nominal, to obtain the desired height of the base. Cables, ducts and irregularities in the compacted state is subject to override the value of not less than ten millimeters. If the thickness of the sealing layer is more than six millimeters, the seal should be carried out by surface vibrator.
Also frequently used special solutions based on perlite sand, which is especially suited for building insulation equipment. Components of perlite in the main panel is completely non-combustible.
In bitumperlitnyh normal flammability of materials, they are quite resistant to destruction and long-lasting, they do not start insects and rodents.
Not processed perlite is environmentally friendly and completely harmless to health. Perlite bitumizirovanny under certain conditions can have a negative impact. A full study of this problem to date has taken place.
