Flame Retardant

1. A grade fireproof composite board is a completely non-combustible inorganic composite core layer, in extreme high temperature (1500 ℃) it will not ignite, combustion or release any toxic gases, the real exposure to the flame When the zero drop and zero spread, to ensure the superior fire resistance.
2. Fire rating is Class A.

Stone fire rating for the A-class.

Aluminum veneer mainly used aluminum alloy as raw material, melting at about 650 ℃ high temperature.

Multi-layer composite panel core material is plastic, the highest fire rating B1 level, at high temperatures will be a whole piece of burning, while plastic combustion will produce toxic gases and drip, easy to ignite other objects, many countries have begun to prohibit the use of The

Thermal Conductivity

A fireproof composite plate with inorganic composite core layer, through the national testing authority, internal exposure index reached 0.01 (the national standard is less than or equal to 1); external exposure index reached 0.03 (the national standard is less than or equal to 1.3), the core layer is a special inorganic material, has good insulation properties.

Natural stone, high thermal conductivity, heat conduction fast, poor insulation effect.

Aluminum has good thermal conductivity, so aluminum sheet does not have good insulation function.

The thermal conductivity of plastic is higher, so the thermal insulation performance of aluminum plastic plate is poor.

Convenience

A fireproof composite board has unique advantages of convenient installation, can be adjusted according to the actual site construction, which can be accurate in size, convenient construction system, ordinary workers can install 40 square meters every day, greatly shorten the construction period, to ensure the project closing rapidly, cost saving.

1. stone mainly for T code and back bolt type link, need drilling or slotting, drilling or grooving at the stress caused by damage.
2.while the construction speed is slow, the average worker can install 5 square meters every day, which leads to the increase of labor cost, growth period.

Aluminum veneer complex manufacturing process, delivery period is longer, sewing after painting, transported to the construction site for installation, and can not realize the scene cutting, high accuracy and precision of the construction plan, therefore not only difficult to transport, and the cost is high.

It can be processed on site, convenient and quick.

Physical Property

1.our company a fire retardant composite board, sheet thickness of 3mm, 4mm, 5mm and so on, and inorganic core layer has good ductility and physics.
2.grade a fireproof composite board has high strength, can withstand certain impact, vibration and pressure. The utility model can make various shapes, and the minimum arc radius is 30cm.
3. grade a fireproof composite board, light weight, 4mm weight, 7.8kg per square.

1.stone thickness is thicker than the major, so the weight per square meter, which relative to improve the requirements of the keel, raising the cost.
2.stone compression, earthquake resistance, impact resistance is poor, fragile crack.
3.stone can not make all kinds of special-shaped and modeling, it is difficult to express the designer's ideas and features of the building.

Aluminum sheet is usually made of AA1100 pure aluminium plate or AA3003 aluminum alloy plate, and AA3003 aluminum alloy plate is used in china.

Aluminum plate weight is light, but the strength is low, the impact resistance is poor.

Aesthetics

1. grade a fireproof composite board adopts roller coating process, in the roll coating process, the board surface is always in the temperature curve of one point, without chromatic aberration.
2. The roller is a compression type printing coating, the coating film and non granular surface, pore free surface, very smooth, very smooth surface, beautiful environment, pollutant impermeable, long time not easy to fade deformation.

The color is restricted by natural reasons, the tone is single, there is obvious color difference between the two pieces of stone, the surface of the board is long and easy to fade.

The aluminum single board adopts the spraying process. In the process of spraying, the board surface is always in the temperature curve, and the color difference is easy to appear. Spraying is a kind of electrostatic floating painting, the whole coating film and surface are particles piled up, and microporous, the board surface can only be more smooth, smooth surface, but also easy to be contaminated.

The main material of the inner core of the aluminum-plastic plate is plastic, and the expansion and cold contraction for a long time are easy to cause bulging and cracking, and affect the appearance.

My company's A-class fire composite board with inorganic core layer, no radiation, green.

Stone composition of complex, internal contain a variety of metal elements, radiation is more serious, mainly ammonia.

Aluminum is not renewable resources, the number is limited, the production process for high energy consumption, high pollution, foreign products were eliminated.

Not environmentally friendly, burning the release of toxic gases.

Overall Cost

1. The price of the main material has advantages.
2. keel and other auxiliary materials require low, can save costs.
3. Construction quickly and easily, reduce labor costs.
4. Construction period is short, the project close quickly.

1. The price of the main material is relatively high.
2. keel auxiliary material requirements, the cost also will increase.
3. Construction is more complex, labor costs increase.
4. Long construction period, the project is slow to complete.

The main material price is slightly higher, aluminum veneer later to recover the depreciation, there is a certain residual rate.

The overall cost of aluminum-plastic panels is low.

Weatherability

Very high, the use of fluorocarbon coating (PVDF) for 30 years

General

Flatness

Board flatness is good

Plate flatness slightly worse, better after processing

Board slightly curved, flatness is poor
