1, GRC lightweight partition material
Glass fiber reinforced concrete; This is a fiber cement composite material with alkali-resistant glass fiber as reinforcement and cement mortar as matrix material. Construction of aerated concrete block equipment foundation. Outstanding features are good tensile and bending strength and good toughness. This material is especially suitable for making decorative shapes, showing strong texture. Compared with these exterior wall decoration materials, GRC materials have the greatest advantage that they can meet the individual needs of architects and complete the expression of various decorative shapes and textures.
2. Fiber reinforced low alkalinity cement building board.
This standard specifies the classification, raw materials, technical requirements, test methods, inspection rules, packaging, marking, transportation and storage of fiber reinforced low alkalinity cement building boards. This standard is applicable to building boards made of chrysotile, chopped medium alkali glass fiber or alkali-resistant glass fiber as reinforcing material and low-alkalinity sulphoaluminate cement as cementing material.
Fiber reinforced low alkalinity cement building boards are mainly used for indoor non-load-bearing interior partitions and ceiling boards.
3, autoclaved aerated concrete slab
Autoclaved aerated concrete slab is a new lightweight, porous and green building material, which takes cement, lime and silica sand as the main raw materials, and then adds different amounts of anti-corrosion steel mesh according to the structural requirements. After high temperature and high pressure steam curing, the porous crystal autoclaved aerated concrete slab is generated by reaction. Its density is less than that of ordinary cement materials, and it has excellent fire resistance, fire prevention, sound insulation and heat insulation.
4, lightweight aggregate concrete lath,
It is mainly composed of foam lightweight aggregate concrete slats, and a polystyrene foam plastic interlayer is arranged in the foam lightweight aggregate concrete slats. At least two of the four sides of the foam lightweight aggregate concrete lath are arc-shaped. During installation, the joint of the two plates is rigidly connected in a double arc shape, and the joint is made of magnesium oxychloride cement and other materials, which is not easy to crack.
5, steel wire mesh frame cement sandwich panel.
In the past, the core materials used in color steel sandwich panels mainly included phenolic foam, polystyrene, extruded polystyrene, rigid polyurethane, polyester and rock wool. Phenolic foam has excellent fire and heat insulation performance, which is irreplaceable by other materials. For example, the thermal insulation effect of phenolic foam is more than twice that of polystyrene, and its fire resistance is higher than that of polyurethane. When polyurethane burns, it will release thick smoke containing hydrogen cyanide.
6. Gypsum wallboard
Taking building gypsum as raw material, adding water and stirring, casting and molding lightweight building gypsum products. Fiber, perlite, cement, river sand, fly ash and slag are allowed to be added in production, which has sufficient mechanical strength.
7, metal surface sandwich panel
Metal-faced sandwich panel refers to a structural panel with load-bearing capacity, which is composed of upper and lower metal plates and a core material of thermal insulation material with certain rigidity, such as rock wool and rigid foam plastic. , also known as "sandwich board".
8. Composite lightweight sandwich partition boards and slats
It consists of double-sided medium-density cement fiber waterproof board (100% asbestos-free) and lightweight aggregate concrete core (expanded perlite powder, polystyrene particles, lightweight portland cement, additives, etc.). ).
Features: light, solid, thin, high strength, sound insulation, heat insulation, waterproof, fireproof, moisture-proof, anti-freezing, anti-aging, strong hanging force, impact resistance, nail saw, simple construction, and direct slotting and burying of conduit.
