Discussion on the installation of luotian sesame ash fire surface to keep several ways of sealing.Sesame ash burning surface is a building material that is widely used in construction. Because sesame ash burning surface has the characteristics of natural stone and contains certain iron elements, it is easy to produce chemical reactions in humid environment, which affects the service life of sesame ash burning surface.So, in the installation of sesame ash fire surface to do a good job sealing.Sesame ash fire surface sealing method has many kinds, each has its own characteristics.

First, the sesame ash fire surface seal is sealed by means of empty seam without sealant.In the sesame ash fire on the back of the formation of air convection, the steam out of the outdoor, to prevent the formation of a temperature difference on the surface of the surface of the stone will not be covered with condensed water.If involve the discharge method of rainwater and direction problem, design institute should take into full consideration beforehand when designing, with stone material behind should drain rainwater or condensing water distributive discharge outside wall body, also can two or three, had better each has a gate to discharge rainwater.

Second, sesame ash fire surface seal with neutral sealant to close.It is the sesame ash fire surface of the seam all sealed, so that the rain can not enter the back of the stone, can make the stone dense in dry state, and ensure that the bending strength and shear strength of the sesame ash fire surface unchanged.

Three, sesame ash fire surface seal with half seam seal method to close.Keep the sesame ash burning surface outside the stand of no sealant, so that the facade has a good sense of three-dimensional, in fact is to hide the rubber layer inside the node, but must ensure that the thickness of sealant should be about 6 mm, and can not exceed the width, the width should be determined according to the quality of the rubber calculation.

Above three ways is the main sesame gray surface keep fire sealing way, these three methods have a common characteristic, is the sesame gray on the back of the fire is not waterproof processing, ensure the sesame gray surface inside the dry degree of fire, so as to better guarantee the sesame gray fire to avoid all kinds of water invasion in the environment, protect the sesame gray surface fire, prolonging the life of the stone material, to ensure that the stone adornment effect.
