Coating knowledge: what are the applications of polyvinyl alcohol in the construction coating industry

Core tips: polyvinyl alcohol in building coatings applications mainly include the following aspects: first, in water-soluble coatings as film forming material; two is in polyvinyl acetate emulsion as emulsifier and protective glue; in addition, it can also be used as a component of some indoor putty products Polyvinyl alcohol has been used as the film-forming material of interior wall coating for many years The performance of this kind of coating is better than that of white (chalk) powder In the 1970s, the successful development of polyvinyl alcohol water glass interior wall coating (106 interior wall coating) was a turning point in the development of architectural coatings in China, ending the tradition Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Coatings home news: polyvinyl alcohol in building coatings applications mainly include the following aspects: first, in water-soluble coatings as film forming material; two is in polyvinyl acetate emulsion as emulsifier and protective glue; in addition, it can also be used as a part of indoor putty products Polyvinyl alcohol has been used as the film-forming material of interior wall coating for many years The performance of this kind of coating is better than that of white (chalk) powder In the 1970s, the successful development of polyvinyl alcohol water glass interior wall coating (106 interior wall coating) was a turning point in the development of architectural coatings in China, ending the traditional practice of using lime water as interior wall facing material 106 interior wall coating once played an important role in interior wall decoration materials However, this kind of coating is not scrub resistant and has poor water resistance Soon, on the basis of this kind of coating, various modified interior wall coatings came out one after another, and the performance of the coating film has been improved in varying degrees Especially in order to improve the water resistance, polyvinyl formal (107 glue) is also used to replace polyvinyl alcohol in whole or in part Polyvinyl alcohol and its various modified water-soluble coatings have low grade, poor performance, and different degrees of formaldehyde, which is not conducive to environmental protection, so they are gradually eliminated PVA-1788 polyvinyl alcohol is used as emulsifier of polyvinyl acetate emulsion for latex paint The emulsion obtained from other specifications of polyvinyl alcohol as emulsifier is unstable, and even in the reaction there is a phenomenon of condensation In addition to being an emulsifier, polyvinyl alcohol can also protect the gel from thickening and stability Due to the strong hydrophilicity of polyvinyl alcohol, which affects the water resistance of latex coating, many researches have been carried out to reduce the hydrophilicity of polyvinyl alcohol In the water-resistant putty for interior wall rising in recent days, polyvinyl alcohol is also used as adhesive in combination with other components Especially the appearance of fine powder polyvinyl alcohol provides a cheaper binder for powder putty products Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
