Yu-wall brand of Qingdao interface agents - safety and security of dry concrete interface agent 
 In construction works, the majority of construction enterprises, the use of the owners of the interfacial agent in Qingdao has been very seriously, that is necessary to use concrete interface agent, no additional materials, increase the cost without the use of concrete interface agent. Concrete interface agent also known as the interface treatment agent, is not only firmly bonded to the grassroots level, the surface can be a good new binder solid bond, with two-way affinity materials. In construction works, due to the grass-roots varying degrees of surface features, such as the strong absorbent porous material, a smooth, low water absorption materials, non-porous, non-absorbent materials, as well as the cohesion arising from the contraction and expansion of the cladding material of the substrate follow-up led to bond failure and other circumstances, require the use of concrete treatment agent to enhance the binding force between the two materials. 
 Now a lot of construction site concrete interface agent is not comprehensive enough, and that 108 of the gum can use liquid or 801 plastic against the ordinary portland cement for construction, of course, due to cost control, construction glue is also easier to purchase of hardware and building materials business, decorative materials, the city, everywhere. But this type of construction glue in most cases, the reaction of acrylamide and PVA glue construction glue, and even many manufacturers do not have polyvinyl alcohol, pure acrylamide polymerization, to get the adhesive, as sales of construction glue . But, you know, the acrylamide referred to as the AM, colorless flaky crystals, odorless, melting point 84.5, boiling point 125, soluble in water. The toxicity of acrylamide great harm to the central nervous system, eyes, skin, have a strong stimulating effect. 
 Yu-wall brand of Qingdao interface agent applications and features 
 Buildings and building elements are required to do the mortar surface, this has protective effects on buildings and walls to resist the erosion of wind, rain, snow, and the natural environment of the building, and improve the durability of the building another is to achieve dense, smooth and beautiful decorative effect. This is all built on the basis of the clean surface layer and the substrate effective bond, construction powder-section treatment agent widely used in wall plaster, and after pouring with the binding layer, the renovation of the old wall, is particularly worth mentioning is to ensure the effective bonding of the interface agent deal with the agent often avoid the substrate water, especially water and shrinkage deformation of the light block, but also serve to prevent shrinkage cracking. stabilizing effect on the substrate, which is the largest market for the amount of material. In addition many can not easily be on the dense material of the mortar bond, interface treatment agent as indispensable auxiliary material, but also have a certain market. 
 What are the characteristics of the mortar interface? 
 1) to close the pores of the substrate, reduce the absorbency of the wall, to retard and reduce the moisture from the lightweight masonry pumping cladding mortar to ensure the cladding mortar bonded cementitious material in better conditions. 2) consolidation, to improve the strength of the substrate surface, to ensure that the mortar bond strength 3) take on the role of the masonry and wipe the surface of the bonded bypass to ensure so that the upper wall of mortar and masonry surfaces easier to combine into a solid whole. 4) specific permanent bond strength, no aging, hydration and does not form a durable bond film structure 5) to exempt from the watering process of the second before the plaster to avoid wall shrinkage. 
 Yu-wall brand of Qingdao interface agent part of the project case 
 Many days Qingdao Water Side, the new airport construction projects, sun xingxing, Yuan Shun, affordable housing and other construction works and construction.
