    Q: Matters needing attention in coating application of Jianyuan FCA board outdoor use

    Q: Why is the direction of the long side of the board vertical to the secondary keel when installing the Jianyuan FCA board ceiling?

    Q: How high is the outdoor application of Jianyuan FCA board?

    There are mainly two kinds of systems in the outdoor application of Jianyuan FCA plate, one is flat plate structure, good wall Jianyuan FCA board exterior wall system; the other is drape structure, external wall drape board system. If the commonly used structure is used, the good wall exterior wall system is generally used in high-rise buildings, such as buildings within 30 meters; the drape plate system is generally used in low-rise buildings, such as various villas and club buildings.

    Q: In wet areas, what should I pay attention to for the waterproof of the partition wall of porcelain Jianyuan FCA board?

    At the bottom of the wall, the fine aggregate concrete must be used to make a water stop not less than 100 mm high to ensure that water can not pass through the bottom of the wall. After the installation of the board, a layer of silicone waterproof agent should be used on the surface of the porcelain Jianyuan FCA board. Generally, the wall in the wet area must be treated with waterproof layer, and then pasted with stone or ceramic tile.

    Q: In addition to waterproof treatment, what should be paid attention to?

    Please use special tile glue, do not use ordinary cement mortar, because the construction control is not good, prone to hollowing phenomenon, and the construction speed will be reduced.

    As some stones are very heavy, what are the restrictions on the height of the wall? For details, please consult 800-830-1103 technical free hotline or refer to "partition parameter table".

    For the wall used in wet areas, expansion joints must be left in the partition wall every six board width. For the method of expansion joint, please refer to PDF download of porcelain Jianyuan FCA board.

    Q: What is the principle of leaving expansion joint on partition wall or ceiling?

    When the length of the wall or ceiling in a certain direction is more than 10 meters, the expansion joint must be reserved; the principle of expansion joint: the ceiling or partition wall on both sides of the expansion joint must be completely isolated and separated, and there is space for the slight deformation of the ceiling or partition wall to be released.

    The expansion joint is visible, even if it can be sealed with elastic material, the effectiveness of the expansion joint should be ensured.

    Q: How to keep the expansion joint of partition wall?

    Q: How to retain the expansion joint of ceiling?

    Q: How to understand the sound absorption of Jianyuan FCA board?

    Sound absorption is the conversion of sound energy into heat energy, which can be used to reduce the sound level in the room, but it can not reduce the sound between different rooms. Sound absorption is usually measured by the ratio of absorbed sound energy to incident sound energy, and the sound absorption coefficient ranges from 0 to 1.

    Different frequencies have different coefficients. When using the perforated Jianyuan FCA plate as the coefficient component, considering from the incident sound wave, the air at the perforated part is a mass block, and the cavity at the back of the plate is a large spring. At the frequency corresponding to the mass block and the spring, the mass block on the spring will resonate. Therefore, the incident sound wave close to the resonant frequency of the cavity will be absorbed. This is the sound absorption principle of perforated Jianyuan FCA plate (Helmholtz principle).

    Q: How to understand the sound insulation of Jianyuan FCA board components (partition wall, ceiling)?

    Different from sound absorption, the main sound insulation index is based on the decibel level of transmission coefficient. The transmission coefficient is the ratio of transmitted sound energy to incident sound energy. The sound insulation loss is the reciprocal of the transmission coefficient based on 10, in dB. We can also roughly understand the sound attenuation through the partition between the sound source and the listener. Like sound absorption, sound insulation loss is also related to sound frequency. It can be understood by referring to the figure below.

    Q: How to design and construct a good sound insulation partition wall with light steel keel?

    In the design of sound insulation wall, the following methods can be used to increase the sound insulation of the wall:

    1. Different thickness plates are used on both sides of the wall to avoid resonance propagation of sound;

    2. Fill the interior of the wall with sound-absorbing materials, such as rock wool;

    3. Increase the size of vertical keel to improve the sound insulation;

    4. Use independent keel or double row keel to avoid the formation of sound bridge.

    During installation, please pay attention to the following items:

    1. The plates must be staggered;

    2. Quality selection
