How to choose waterproof roof waterproof material?
First, the waterproof function of the roof building waterproof material requires waterproofing of buildings and structures is achieved by the material with waterproof properties, the quality of the waterproof material is directly related to the durability of the waterproof layer, the quality of the waterproof project is largely Depends on the performance and quality of the waterproof material, the material is the basis of waterproofing. When we carry out waterproof construction, the waterproof material used must comply with the national or industry material quality standards, and should meet the design requirements. However, different waterproof practices require different waterproofing requirements for the material.
The common requirements for building waterproof materials are as follows:
(1) It has good weather resistance, and it should have a certain ability to withstand light, heat and ozone.
(2) Has anti-water permeability and acid and alkali resistance.
(3) It has certain adaptability to the external temperature and external force, that is, the tensile strength of the material should be high to withstand the temperature change and the distortion caused by various external forces and the stretching and cracking of the base layer.
(4) The integrity is good, and it can not only maintain its own adhesiveness, but also can firmly bond with the base layer with higher peeling strength to form a stable impervious whole.
For different parts of the waterproof project, its waterproof material requirements also have their own priorities, the specific requirements are as follows:
(1) The weather resistance, temperature resistance, and external force resistance of the waterproof material used in the roof waterproofing project are particularly important. Because the roof waterproofing layer, especially the exposed waterproof layer without a warm house, has been subjected to wind, rain, sun, snow and ice and other adverse natural environment invasion and deformation of the grassroots structure.
(2) Waterproof materials used in underground waterproofing projects must have good impermeability and elongation, and have good overall water permeability. These requirements are based on the continuous erosion of groundwater, the relatively large water, and the possible deformation of underground structures.
(3) The waterproof material selected for the waterproofing of the indoor toilet room should be suitable for the change of the shape of the base layer and be conducive to the laying of the pipeline equipment. The excellent watertightness and the seamless overall film are the most ideal. This is due to the characteristics of small area, many wearing holes, many yin and yang angles, many health equipments, and the complex connection structure of the ground, floor, and wall.
(4) The waterproof material chosen for the construction of waterproofing projects for building plugging boards should be based on materials with good weathering resistance, high elongation, adhesion, and sagging resistance. Generally, waterproof sealing materials are selected and supplemented with It is advisable to provide thermal insulation materials for cushioning. This is proposed in consideration of the need for the plug body to withstand the comprehensive functions of heat preservation, heat insulation and waterproofing, and the special form of the joint construction of the gap structure.
(5) The waterproof material selected for the waterproof construction of special structures shall be selected as appropriate by the design according to the characteristics of different projects and the different requirements of the use functions.
