Coating knowledge: systematic comparison between varnish and base film

Core tip: someone always asks, why do I use base film when I have varnish? Why is base film better than varnish? Here is a systematic comparison to answer questions and solve doubts First of all, from the perspective of environmental protection, the chemical composition of varnish contains nitro, alcohol and other substances, which are volatile, so it will volatilize the irritant odor in 1 to 6 months If you buy some varnish with poor quality, it will cause great harm to human body; at the same time, the construction auxiliary materials of varnish need to use Tianna water and pine water-saving, which is also volatile The basement membrane of wallpaper is different Because the basement membrane itself is water-based, there is no pungent smell, and no other auxiliary materials are needed 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 Paint Home News: someone always asks, why do I use base film for varnish? Why is base film better than varnish? Here is a systematic comparison, so as to answer questions and solve doubts First of all, from the perspective of environmental protection, the chemical composition of varnish contains nitro, alcohol and other substances, which are volatile, so it will volatilize the irritant odor in 1 to 6 months If you buy some varnish with poor quality, it will cause great harm to human body; at the same time, the construction auxiliary materials of varnish need to use Tianna water and pine water-saving, which is also volatile The base film of wallpaper is different, because the base film of wallpaper itself is water as the carrier, there is no pungent smell, no need for other auxiliary materials, as long as clear water; secondly, from the perspective of construction, because the base film only needs to be mixed with water, which is more convenient than varnish, and the drying time of varnish generally needs 3 to 36 hours, and the base film only needs one hour, which saves construction time; Thirdly, from the perspective of protecting wallpaper, varnish is not only corrosive in itself, but also can not effectively isolate the alkaline wall from the corrosion of wallpaper, which will greatly shorten the life of wallpaper, which for some precious wallpaper, is simply abuse The base film of wallpaper can form a dense protective film on the wall, which can effectively block the damage of water and alkaline substances on the wallpaper, prevent the wallpaper from turning yellow and prolong the wallpaper life; In addition, from the cost point of view, every 100 square meters of wall needs 8 liters of varnish plus 8 liters of Tianna water or loose water saving, the cost is about 90 to 140 yuan, and only 5 liters of base film and some clean water are needed with base film, the cost is about 70 to 115 yuan 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,
