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. Thermal properties of wall materials important for building energy efficiency. Building exterior wall materials, the main structure of the Southern Yue detect both low thermal conductivity, with insulation, thermal insulation function and water resistance, but also has a large heat capacity, the main structure of the high-tech area detector, in order to improve the internal structure temperature stability, reducing winter heating and summer cooling process energy consumption. 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.

Superabsorbents depends not only on the material itself hydrophilic, but also its size and pore characteristics related to porosity. General porosity, the stronger the water absorption. Closed pores, water can not enter; coarse pores open, easy to suck water; with many tiny pores opening material, Fanxian main structure testing, the water absorption capacity particularly strong. Absorption of various materials vary widely, such as: dense granite mass water absorption of 01% ~ 07%; ordinary concrete of 2% to 3%; ordinary clay brick is 8% to 20%; and wood quality water absorption and other lightweight materials often greater than 100%. Water has many adverse effects on the material, which increases the apparent density of the material, enhance the thermal conductivity, strength is reduced, volume expansion, susceptible to frost damage, a large water absorption and therefore the material is unfavorable. In construction projects often apply some hydrophobic materials to reduce water absorption base material of construction sites, so as to achieve the purpose of waterproof. Absorbent material refers to the nature of the material to absorb moisture in humid air, the size of hygroscopic moisture content expressed.
