The Second Generation Water Reducing Agent Naphthalene series superplasticizer is a non-air-entraining superplasticizer synthesized by chemical industry. The chemical name is naphthalenesulfonate formaldehyde condensate, which has a strong dispersing effect on cement particles. For the preparation of large-fluid concrete, the cast-in-place concrete and prefabricated components with early strength and high strength requirements have a good use effect, and can comprehensively improve and improve various properties of concrete. It is widely used in highways, bridges, dams, and dams. Ports, tunnels, electric power, water conservancy and industrial and civil construction projects, steam curing and natural curing prefabricated components, etc. MF Powder Water Reducer,Water Reducing Agent MF Powder,Waterproofing Chemical For Slab,Sika Corrosion Inhibitor Shenyang East Chemical Science-Tech Co., Ltd. , https://www.eastchemy.com
The application of small-aperture nesting technology is currently being tested for the extraction of mechanical properties for analysis. Because high-speed components, such as large generator rotors and motor shafts, require reliable material reliability, in addition to testing methods such as flaw detection, the test is performed at the working position and the test bar is extracted. Therefore, the structure of the small hole nesting processing device is required to be tight.
