Pharmaceutical Multilayer Composite FiIms

Pharmaceutical Multilayer Composite FiIms

Composite membrane is a composite geomembrane formed by pasting geotextile on one or both sides of the membrane. Its form has one cloth and one film, and two cloth and one film. The width is 4-6m, the weight is 200—1500g/m2, the physical and mechanical properties such as tensile resistance, tear resistance, bursting resistance are high, the product has high strength, good elongation performance, large deformation modulus, acid and alkali resistance, Corrosion resistance, aging resistance, and good anti-seepage performance. It can meet the needs of civil engineering such as water conservancy, municipal administration, construction, transportation, subway, tunnel, and engineering construction for anti-seepage, isolation, reinforcement, crack prevention and reinforcement. Because of its selection of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments. It is often used for the anti-seepage treatment of dams and drainage ditches, and the anti-fouling treatment of waste material yards.

Pharmaceutical Aluminum Foil

Aluminum foil is a very important product in the development of the national economy and people's daily life. It has a wide range of uses in the fields of packaging, electrical and construction. It is one of the aluminum products with the most production processes and the most difficult processing technology. "Aluminum Foil Materials" systematically summarizes the research results in the preparation and processing of aluminum foil materials, such as melting and casting, homogenization, hot rolling, cold rolling, intermediate annealing, precipitation annealing, etc. The main contents include: alloy system and alloy phase of aluminum foil material , The performance of aluminum foil, the production process of aluminum foil, the structure control and quality evaluation of aluminum foil, the high temperature phase change in aluminum foil material, the medium temperature phase change in aluminum foil material, the low temperature phase change in aluminum foil material, the effect of chemical composition on the structure and performance of aluminum foil The influence of process parameters on the performance of aluminum foil, etc.
