Paint knowledge | epoxy coating price epoxy coating construction process

Core tip: now whether it's houses or buildings, or other means of transportation for people's use, it's required to have good performance, and look beautiful outside, which conforms to the aesthetic concept of Chinese people We will decorate the house The coating is essential Here we introduce a special coating - epoxy coating There are two kinds of epoxy coating: Oil-based epoxy coating and water-based epoxy coating They can also be divided into wear-resistant epoxy coating, epoxy anticorrosive coating, anti-static epoxy coating and architectural epoxy decorative coating according to their performance Epoxy coating is developed and produced according to the needs of customers Different customers have different needs Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: now whether it's a house or a building, or other means of transportation for people's use, it's required to have good performance, and look beautiful outside, in line with the aesthetic concept of Chinese people We will decorate the house The coating is essential Here we introduce a special coating - epoxy coating There are two kinds of epoxy coating: Oil-based epoxy coating and water-based epoxy coating They can also be divided into wear-resistant epoxy coating, epoxy anticorrosive coating, anti-static epoxy coating and architectural epoxy decorative coating according to their performance Epoxy coating is developed and produced according to the needs of customers Different customers have different needs, so the products produced are different It may be caused by slightly different components in the same coating At present, epoxy coating is mainly used in bridges, coal facilities, underwater layers and other construction facilities, as well as the chassis surface of vehicles to prevent steel rust The price of epoxy floor coating in the market is about 120 yuan to 1000 yuan Xinletian brand is recommended, the price is 500 yuan, the quality is OK, odorless, environmental protection products The application of epoxy coating should talk about the application of epoxy coating, the first thing to say is its performance Because these performance is the most fundamental place of its wide application The functions of epoxy resin coating include strong corrosion resistance, wear resistance, salt fog resistance, high solid content, strong adhesion, high hardness, acid and alkali resistance, high gloss and fullness These advantages make epoxy coating competent for any difficult environment Let's analyze several performances in detail When it comes to the physical and mechanical properties of epoxy coatings, we know through investigation and analysis that the molecular structure of this epoxy resin contains a large number of polar groups, such as hydroxyl and ether groups In addition, the active epoxy energy in the curing process of the coating reacts with the interface metal atoms, and finally forms a very strong special chemical bond It ensures the excellent adhesion between the coating and the substrate, especially for the solventless epoxy anticorrosive coating, which has excellent wet adhesion, thus ensuring the excellent durability of the coating in the corrosive environment of liquid medium Standard of epoxy coating standard of epoxy coating -- anticorrosive performance index The viscosity of epoxy coating is more than 80, the test method is GB / t1723-1993, the fineness is GB / t1724-1979 (1989), the result is less than 100um, the drying time is GB / t1727-1979 (1989), the calculated surface drying time is less than 4 hours, the actual drying time is less than 24 hours, the adhesion is GB / t1731-1993, the result is less than level 2, and the impact resistance is GB / T 1732-1993 test method, the result is 50cm; epoxy coating construction process 1 Before construction, base surface treatment should be carried out 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 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,
