Coating knowledge: epoxy coating construction process

Core tip: epoxy coating is a two-component heavy-duty anti-corrosion coating, which is prepared by advanced process with long-life chlorosulfonated polyethylene rubber as main modifier and special additives and additives, aiming at the problems of poor weather resistance and insufficient pulverization There are many kinds of epoxy coatings, including solvent-based epoxy coating, solvent-free epoxy coating and water-based epoxy coating according to the coating state; white dry single component, two-component and multi-component liquid epoxy coating according to the curing form Characteristics of epoxy coating 1 Not only good corrosion resistance but also water resistance, durability, weather resistance, etc 2 Interpenetrating mesh wear-resistant coating effectively prevents the coating from changing 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 Home of coatings: epoxy coating is a two-component heavy-duty anti-corrosion coating prepared by advanced technology, aiming at the problems of poor weather resistance and easy pulverization of epoxy heavy-duty anti-corrosion coating Long life chlorosulfonated polyethylene rubber is used as the main modifier, and special additives and additives are added There are many kinds of epoxy coatings, including solvent-based epoxy coating, solvent-free epoxy coating and water-based epoxy coating according to the coating state; white dry single component, two-component and multi-component liquid epoxy coating according to the curing form Characteristics of epoxy coating 1 Not only good corrosion resistance but also water resistance, durability, weather resistance, etc 2 Interpenetrating mesh wear-resistant coating can effectively prevent the change of coating and improve the weather resistance of coating 3 The construction is simple and convenient It is not limited by the site and can be used as needed Epoxy coating construction process 1 Base treatment shall be carried out before construction 2 First mix the coating until there is no deposit at the bottom of the barrel, then add the winter curing agent according to the ratio of coating and curing agent 10:1, and then fully mix and mature for 10-15 minutes before use 3 The surface treatment requires that the surface of coated metal, sand blasting and shot blasting shall reach the international Sa2.5 level, and shall be cleaned after oil removal The surface shall be kept dry and painted within 4 hours When painting concrete, it shall be dried before painting until the water content is less than or equal to 10%, and the surface shall also be cleaned 4 Spray with high pressure and air pressure The dry film thickness is about 60 μ M brush by hand The dry film thickness is about 55 μ M Precautions for epoxy coating construction 1 After the coating is prepared, it is better to use up within 2 hours (20 ℃), if there is any primer that is not used up, it cannot be poured into the original paint again 2 If the factors such as coating technology, coating method, surface condition, shape and surface area are not considered during construction, the primer consumption is generally 0.2kg/m2 3 If the coating is indeed too thick, special diluent can be added appropriately, with the dosage of 3-10% 4 In order to smooth the coating, it is better to use high-pressure airless spraying Airless spraying can only be selected under the condition of no high-pressure airless spraying, while manual painting is the third coating method 5 Clean the tools with special diluent after use If the ambient temperature is lower than 10 ℃, the time can be prolonged 6 After the last finishing coat is applied, it can only be used 7 days later 7 Storage and transportation: it is inflammable, which should be stored away from the fire source and ventilated and dry place, and the storage temperature should not exceed 40 ℃ No collision, no contact with water The above content is the "epoxy coating" that Xiaobian introduced to you Continue to pay attention to our website, and you will always find the knowledge you want [focus on WeChat official account "paint net"; pay attention to surprises, scan code to see if your husband is selling paint..
