    摘要： A method and a PVB cleaning and/or upgrading system for cleaning and upgrading post-consumer and/or post-industrial polyvinylbutyral (PVB). The system comprises an extraction station for extraction with liquid or supercritical carbon dioxide. The extraction station comprises a scalable container (13) with means for introducing pressurized liquid carbon dioxide into the container and means (4) for stirring PVB material. The station further comprises transfer means for transferring the pressurized liquid carbon dioxide containing extracted plasticizer and/or contaminants from the container to a distillation unit (18). The distillation unit separates extracted plasticizer and/or contaminants from the carbon dioxide, by evaporation of the liquidified CO2. The system further comprises pressurizing means (21), such as a compressor, for pressurizing and liquidifying of the CO2 evaporated in the distillation unit (18). The recovered CO2 is liquidized and pressurized CO2 to the scalable container (13), preferably via a CO2 storage (15). The PVB material is preferably initially subjected to one or more alkaline washing steps, preferably prior to the extraction with CO2. The system and method effectively removes contaminants and/or additives from the PVB and eliminates the use of organic solvents during the extraction step(s).

    摘要： A method for treating surfaces of cement, concrete, mortar or floor screed comprising applying at least one layer of a composition comprising of 2-20% by weight of particles of plasticized polyvinyl butyral (PVB) dispersed in water in an amount of 100 g/m 2 -600 g/m 2 . This ensures that the surfaces exhibit improved resistance to wear and reduced creation of dust during wear, i.e. a dust binding effect is achieved and protects the surfaces from being stained. The application of the aqueous PVB dispersion provides improved adhesion of conventional top coatings, such as epoxy or polyurethane (PU) based resins and results in a brighter surface on the treated surfaces.
    A composition and uses are also disclosed.
