How to install keel for gypsum board composite glass wool ceiling? It is light, high strength and thin, and gypsum board processing is very convenient

gypsum board gypsum board composite glass wool ceiling how to install keel perforated gypsum board is a commonly used decorative material in the process of building decoration. With its characteristics of light weight, high strength, small thickness, easy processing and so on, it is widely used in the decoration of various residences, offices, shops and other places. When carrying out gypsum board ceiling engineering, there are often some requirements that we need to understand, Then follow our professional perforated gypsum board manufacturer to learn about it

gypsum board ceiling requirements - selection method

(1) look at the surface: the perforated gypsum board manufacturer suggests that when you choose gypsum board, find a place with sufficient light and observe carefully. The surface of a good gypsum board should be smooth and flat, and there should be no defects such as pores, stains, cracks, corners, uneven colors and incomplete patterns

one side of the gypsum board should not be ignored. It can be seen whether the gypsum texture is dense and there is no hollowing. The harder the gypsum board is, the more durable it is. You can't buy an empty gypsum board

(2) listen to the sound: gently tap the gypsum board with your fingers. If the sound is boring, it means it is durable; If it makes a very empty sound, it means that there is an empty drum on the board with bad texture

the faucet is to check the elasticity of gypsum board, but it can't prove that you can cut it into eight pieces on one palm. Don't be violent

(3) quantity deviation: the allowable deviation of gypsum board size, straightness and right angle deviation should meet the product qualification standard. If the deviation of the decorative gypsum board is too large, the joints of the ceiling will be misaligned, and the whole surface will be uneven, which will reduce the value of your home

it takes gypsum as the main material, adds fiber, adhesive and modifier, and is made by mixing, pressing and drying. It has the characteristics of fire prevention, sound insulation, heat insulation, light weight, high strength, small shrinkage, good stability, non aging, anti moth, and can be constructed by nailing, sawing, planing, gluing and other methods. It is widely used in ceiling, partition, interior wall and veneer. Paper faced gypsum board is often used as ceiling material in home decoration

in order to achieve good sound insulation effect, the installation method of sound-absorbing board must be very simple, otherwise it is difficult to achieve the ideal sound insulation effect. Professional acoustic engineers know that if a wall can be soundproof by X decibels in the laboratory, it is often soundproof by only X-2 decibels in actual projects, or even less. There are two main reasons why the sound insulation value of the wall in the actual project is lower than the laboratory test value: including the lateral sound transmission problem in the actual project, and the installation quality of the wall panel in the actual project is not as good as that of the professionals in the laboratory. Therefore, the installation of sound-absorbing panels must be simple, otherwise the installation personnel on site will certainly make mistakes, resulting in the sound insulation value of the wall not reaching the sound insulation target. For example, the elastic horizontal bar used to be used more in the United States, which itself is a good sound insulation means and product. The use of the elastic horizontal bar in the laboratory can improve the sound insulation effect of the lightweight gypsum board wall by 5-10 dB. However, in practical projects, the installation workers are often unable to accurately install the plate on the elastic horizontal bar, resulting in a very limited improvement in the actual sound insulation effect of the wall
