Overview

Inorganic fiber spray performance

Inorganic fiber spraying series products are sprayed on the surface of the building substrate by ultra-fine inorganic fiber cotton and water-based special environmental protection adhesive through Weitao's professional spraying equipment. After natural drying, it forms a new type of thermal insulation, heat insulation, noise reduction, and sound absorption spraying product that is airtight, seamless, overall stable, and elastic. After using spraying technology, an airtight heat insulation and sound absorption layer similar to carpet texture is formed on the surface of the building, which fundamentally solves the problem of poor airtightness, many seams, complicated installation procedures and easy aging of traditional materials (polystyrene board, glass wool felt and other profiles) , deformation, etc.), fiber spraying products can better solve energy loss, reduce operating costs, and improve the overall thermal insulation performance of the building to a greater extent. The use of spraying construction is arbitrarily designed to meet the designer's design arbitrariness. Applicable to any complex structure and special-shaped structure surface. Using mechanized construction. High efficiency, can be directly sprayed on the surface of wood, steel, concrete, gypsum board, glass and other materials. It solves the complicated process of traditional support, hanging parts and reinforcement materials. The construction period is greatly shortened. The surface of inorganic fiber spraying can be treated with different colors and can also be used in combination with other decorative materials to enhance its aesthetics and decorative effect.

Inorganic fiber spraying characteristics

Insulation (insulation) performance

1. F-19 series inorganic fiber spraying products, after testing, the thermal conductivity λF-19=0.035w/m•k, which ensures good (thermal insulation) performance.

2. F-19 series inorganic fiber spraying products are especially suitable for spraying on complex structures or special-shaped structures, so that the thermal insulation (heat insulation) layer forms an airtight and seamless whole, which greatly improves the thermal insulation performance.

Fire performance (Class A non-combustible)

F-19 series inorganic fiber spraying products are natural inorganic substances, which are class A non-combustible materials after testing. This feature meets the requirements of the fire protection rating of the "Code for Fire Protection Design of Auto Garages, Repair Garages, and Parking Lots" (GB50067-97), which is unmatched by other materials.

Adaptability to complex structures

F-19 series inorganic fiber spraying products can be directly sprayed on any medium such as steel structure, concrete, etc., with high-efficiency mechanical and automatic construction operations, and can be easily sprayed on any complex (special-shaped) structure or densely populated pipeline areas. The construction is convenient and flexible, and the construction time is greatly shortened. deadline.

Sound insulation performance (reduce rain noise)

F-19 series inorganic fiber spraying products have a three-dimensional network structure with a certain strength. After spraying, they form an overall airtight structure. This feature ensures that it has good sound insulation performance. For lightweight roofs, it can greatly reduce rain noise.

F-19: 50mm weighted sound insulation = 29dB

Sound absorption and noise reduction performance

The three-dimensional network structure of F-19 series inorganic fiber spraying products attenuates the sound wave energy, so F-19 fiber spraying products have good sound absorption performance.

Safety and environmental protection

F-19 series inorganic fiber spraying products are non-toxic, tasteless, mildew-free, and dust-free; water-based environmental protection glue, with a pH value of 7, does not corrode concrete and steel structures. .

decorative

F-19 series inorganic fiber spraying products can be directly exposed outside after spraying. In order to ensure good acoustic effect, there is no need to attach other materials to the surface of the sprayed coating, but the surface can be treated with different colors to increase its aesthetics and decorative effect.

Spraying process

1. F-19 series inorganic fiber spraying products adopt special spraying equipment.

2. Inorganic fiber cotton and special matching water-based adhesive are sprayed by special spraying equipment, mixed evenly in an instant, and then sprayed on the surface of the object to be sprayed to form a three-dimensional airtight thermal insulation (heat insulation) and sound-absorbing sound-insulating layer with a certain strength. .

Technical indicators of inorganic fiber spraying

It is made of ultra-fine inorganic cotton and water-based special environmental protection adhesive sprayed by professional equipment. Its main properties are fireproof class A, heat preservation, sound absorption, sound insulation, anti-condensation, etc. Widely used in basement ceilings, equipment rooms, large (special-shaped) stadiums with complex structures, museums, transportation hubs and other fields.
