Product Description:
Product Introduction of EPDM Waterproof Membrane
EPDM waterproof membrane is of high elasticity with best performance among high polymer waterproof material it’s made of ternary ethylene-pro-pylene rubber.
We owe the world-advanced equipment of cold feeding extrusion and continuous vulcanization technology. With the best performance among high polymer waterproof materials, EPDM is of exceptional elasticity and will not split or cracked under normal building movement.

- Q:Civil engineering materials on the prospects for talent employment, a little more
- Now the employment environment is bad, many famous university graduates can not find counterparts work, it is recommended to carefully choose to read the professional, we must consider the employment problem, do not let yourself regret
- Q:What is the actual state of the bar in civil engineering?
- (3) the basis of inorganic materials. Candidates according to their future professional research direction, only from the three parts of the content to choose one of the parts (three-election), the three- The material, including the basic concepts of material mechanics, axial stretching and compression, reverse, bending the internal force of the bar, stress, deformation and other calculations and strength, stiffness conditions of the application , The geometric properties of the section, the stress and strain analysis and the strength theory, the combined deformation, the pressure bar stability, the energy method and so on.It requires the candidate to master the basic concept and the basic theory of the material mechanics, and has the ability to analyze and deal with the basic problem of material mechanics. 2.1 examination content and examination requirements 1. Material mechanics overview Deformed, isotropic and anisotropic elastomer, elastic body of the force and deformation characteristics; engineering structure and components, rods of the main form of force and deformation.
- Q:Civil engineering, machinery, materials and finance which relatively good employment?
- Of course, is the civil ah I give you analysis of the material of the wide range of professional employment, but the depth is not enough wages ah what is not ideal employment rate is not too high (I am the material you do not be his name scared) unless you are Submit the material of the professional or you decide to study the future
- Q:Civil Engineering Materials Laboratory electricity about how much watts
- This is hard to say, the laboratory equipment to ask the owners to know the electricity
- Q:What are the classification of civil engineering graduate students?
- After graduation, the main employment units in the past three years, the supply and demand ratio of graduates 1: 6. After graduation in the housing construction, geotechnical and underground engineering, road and bridge engineering and other civil engineering design, construction, management, investment, real estate development, research and education departments engaged in technical or management work.
- Q:Which version of the material mechanics (author) is suitable for civil engineering this profession?
- According to your own situation and school
- Q:Read materials science and engineering or civil engineering, it is tangled ah, we discuss together!
- Material science and engineering development space is relatively large, the market prospect is better. Civil engineering threshold is low, the market gold content as materials science and engineering.
- Q:What are the four major mechanics in civil engineering?
- You should not be civil engineering, engineering mechanics contains the theory, materials, structural mechanics knowledge, agreed to theoretical mechanics, material mechanics, structural mechanics, soil mechanics for the four major civil mechanics
- Q:Material molding and control technology and civil engineering is not near professional?
- No, one belongs to the material college, there are civil is not, are very good, very different.
- Q:What are the basic principles of civil material selection?
- Security: There is no doubt that in the specified period of time, there is a certain quality assurance
