产品描述

  Expanded perlite is a non-toxic, tasteless, incombustible, does not rot, resistant to acid and alkali, heat preservation, sound insulation, internal structure of a honeycomb products, is by the acidic volcanic glass lava (perlite) by crushing, sieving to a certain size, then through preheating, delay of above 1400 ℃ high temperature sintering and made of a white or light color of high quality insulation material, can be made with different cement preparation such as hydrophobic perlite insulation board, perlite sound-absorbing board, partition panel, fire prevention board, etc. This product is mainly used for building roof and wall heat preservation, heat insulation; Light aggregate of building materials; All kinds of industrial equipment, pipe insulation blanket; The walls of all kinds of cryogenic, cold storage engineering; Agriculture and horticulture soilless cultivation, soil improvement, retention of fat, etc., are widely used in petroleum, chemical industry, electric power, building, metallurgy, etc.
Hydrophobic perlite
  Hydrophobic perlite is a kind of new thermal insulation material, its low thermal conductivity, ordinary around 0.045 W/m.k, lowest 0.041 W/m.k. Its appearance has a sealed glass shell layer, make itself has high compressive strength, not easy to damage, which can greatly reduce the breakage in the using process, make the practice effectively maintain the heat preservation effect. At the same time reduces the data of water imbibition, reduces with the proportion of water added, make whole dry solid time significantly shortened, help to progress the construction efficiency.
Features:
1. The hydrophobic perlite non-toxic, tasteless, environmental protection; Hydrophobic perlite lightweight, fire prevention, moistureproof, corrosion resistance; Hydrophobic perlite construction is convenient, lightweight, high strength, heat insulation heat preservation; Hydrophobic perlite insulation board (FSG) conforms to the national standard GB8624-2006 grade a1 incombustible standard.
2. The pulp quality hard, plasma surface fine, high bond strength, crack resistance is strong, no crack, not incite.
3. The product easy to construction, simple operation, using the bento, appropriate use of all kinds of different construction level of personnel, can daub, spraying or piece of paste.
4. Suitable for all kinds of wall, roof, roof, metal structure, heat preservation heat insulation and fire prevention of wood structure housing.
5. More appropriate type is applied to the water conservancy project, hydropower station construction, processing the levee or waterproof LanShui engineering because by water and the water layer on the temperature difference between the formation of the cracking problem. The durable service life, stable performance.
Second, the areas of application:
1, the hydrophobic expanded perlite as the particle diameter of 0.15 ~ 1.5 mm of porous air particles, is the first selection of filling materials.
2, low bulk density, between 0.06 ~ 0.20 g/cm3. As polymer filler material, far less than other mineral filling product consumption, load weight is small, save the polymer injection amount, so can reduce the product cost.
3, low price, based on the hydrophobic expanded perlite small bulk density, compared with other filling materials in the same weight of cutting in polymer, reduce production cost.
4, electrical insulation, hydrophobic bo changes of good electricity insulativity, as filling material can be used for various electrical switchgear and insulating materials.
5, sound insulation, hydrophobic expanded perlite can block and the absorption of sound, can be used for sound insulation materials.
6, acid and alkali resistant, hydrophobic expanded perlite main composition is SiO2 and Al2O3, close to neutral, in all kinds of solvents, acid, alkali, salt nature is stable.
7, low heat conduction coefficient, the coefficient of thermal conductivity in (0.036-0.054 w/m.k), hydrophobic vitrified beads can be used for heat insulation material and thermal insulation material.
8 and good thermal stability. Thermal stability of more than 1000 degrees Celsius, especially suitable for refractory, fire prevention, flame retardant materials.
9, flame retardant. Hydrophobic expanded perlite as the inorganic metal oxides, less than 1000 degrees Celsius, the high temperature decomposition, not changeful form, as polymer filler material can improve the flame retardant properties of polymer, used in building materials and paint coating industry.
10, low water absorption rate, hydrophobic expanded perlite bibulous rate is less than 10%.

Obturator perlite
  Introduction: obturator perlite (also called glaze perlite, light shell perlite), is a new kind of pearlite product. The product consists of a small particle size of perlite material reaches a certain temperature under vertical furnace cascade heating mode from the inside out even after inflation, and the instant high temperature vitrified expanded granular surface, form continuous glass after cooling the qualitative of the surface of the particles, and the internal porous hollow, hollow structure, keep the integrity of the unique mode of production determines the products keep the purity of perlite natural inorganic chemical ingredients. Obturator perlite overcome traditional expansion perlite bibulous rate is large, the characteristics of low strength, poor liquidity, extends the application field of expanded perlite, has high strength, light weight, thermal insulation, good electrical insulating performance, high purity, uniform particles, bibulous rate is low, and other significant characteristics of good viscosity.
  Second, features: intuitive show the micro circular granular, is reflective of the continuous vitrescence smooth outer surface, has obvious capillary adsorption and compressive strength, in the condition of wet slurry with clay, cement and other materials combining degree is high, the liquidity is good.
  Purpose: the external thermal insulation mortar can replace river sand as aggregate, production of high-grade thermal insulation decorative panels, composite insulation coating.then, filter aid materials, refractory brick, the main ingredients of enamel materials, construction, metallurgy, electric insulation, heat pipe kiln and other high-grade thermal insulation material and lightweight filler.
