The full name of PVB is polyvinyl butyral, abbreviated as PVB resin. PVB molecules contain long branched chains, which have good flexibility, excellent transparency, strong adhesion, good light resistance, heat resistance, cold resistance, water resistance, film-forming, solubility, miscibility, high tensile strength and impact resistance etc. Now PVB resin could be divided into two kinds according to the relative molecular weight, i.e. high viscosity type and low viscosity type, in which high viscosity PVB resin is mainly used in the laminated safety glass. Besides, sometimes PVB resin exists in the form of polymer solution, which is widely used for coatings, adhesives, ceramic color film, vacuum aluminum foil, electrical materials, glass steel products, fabric treatment agent, engineering plastics and other fields; and it is a kind of synthetic resin material with a broad prospect for application.
Founded in 2008, Meibang Company is a firm dedicated to the R & D, production, and sales of PVB resin powder and PVB glass interlayer films. Currently, it covers an area of 100 mu and has more than 200 employees. The annual production capacity of PVB glass interlayer films can reach 10,000 tons, and that of resin powder is 8,000 tons. Its main products include high - quality PVB interlayer films for architectural glass, PVB interlayer films for automotive glass, sound - insulating interlayer films for automotive glass, PVB interlayer films for photovoltaic glass, and MBSGP glass inter - reinforcing films.
The exchange capacity is an important index of the performance of ion exchange resin. The larger the exchange rate is, the more ions can be adsorbed by the resin of the same volume, and the larger the water yield in an exchange cycle.
Meibang resin production enterprise returned to work after the Spring Festival, the production workshop is busy. Wan Ruijian walked into the factory and looked at the products, talked with the person in charge of the enterprise, visited the front-line production staff cordially, understood in detail the production operation, market sales and other situations of the enterprise after the festival. Wan Ruijian affirmed that the enterprise would return to work and production in time after the Spring Festival, and encouraged the enterprise to make full use of its power and expand its production.
