Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, is one of the qualification place in Henan Province since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, curtain detection, detection of roads and bridges, air defense projects to detect a number of test qualification and testing laboratories. Expressed as hydrophilic or hydrophobic materials because the molecular structure of the material: hydrophilic material and water molecules between the affinity molecule itself is greater than the cohesive force of water molecules, water molecules and the affinity between the hydrophobic material is less than the water molecules themselves cohesion. Most supplies a hydrophilic material, such as concrete, brick, stone, wood and the like; most organic materials are hydrophobic materials, such as asphalt, plastic, paraffin, water-repellent material prevents the penetration of moisture inside the pores of the material, environmental testing , it is possible to reduce the water absorption of the material. Hydrophobic material has good water resistance, moisture resistance, impermeability, Fangcheng indoor environment testing, often used for proof and waterproof material, it can also be used for surface treatment of hydrophilic material. Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, the town square of indoor environment testing, qualification, Henan Province is one place since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, curtain detection, detection of roads and bridges, air defense projects to detect a number of test qualification and testing laboratories. Thermal properties of wall materials important for building energy efficiency. Building exterior wall materials, both low thermal conductivity, Xichuan indoor environment testing, with insulation, thermal insulation function and water resistance, but also has a large heat capacity, the temperature inside the building in order to improve stability, reduce winter heating and energy consumption during the summer cooling. To meet the thermal conductivity and heat capacity of the two requirements, often outside the large heat capacity of the wall material surface covered with a layer of low thermal conductivity and a waterproof surface layer of the new composite materials. Nanzhao indoor environment testing, Zhengzhou malpractice detection (certification), environmental testing provided by the Construction Engineering Testing Co., Ltd. Henan malpractice. Henan malpractice Construction Engineering Testing Co., Ltd. (www.hnrsjc.cn) (www.rsgcjc.com) is a leader in Zhengzhou, construction, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs.
