Paint knowledge | red lead antirust paint price how much red lead antirust paint construction technology

Core tip: red lead antirust paint is a kind of paint mixed with red lead and dry oil It has good permeability and wettability, soft paint film, strong adhesion, but slow drying In addition, because the red lead ratio is large, it is easy to precipitate, and it will become thick if stored for too long, and the brushing performance is poor The price of red lead antirust paint depends on the percentage of red lead powder The price will be different: 1 Epoxy red lead antirust paint (including 70% red lead powder) 25 yuan / kg 2 Epoxy red lead antirust paint (including 30% red lead powder) 19 yuan / kg What color of red lead antirust paint is generally orange Nowadays, people pay more attention to lead poisoning in order to protect Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: red lead antirust paint is a kind of paint mixed with red lead and dry oil It has good permeability and wettability, soft paint film, strong adhesion, but slow drying In addition, because the red lead ratio is large, it is easy to precipitate, and it will become thick if stored for too long, and the brushing performance is poor The price of red lead antirust paint depends on the percentage of red lead powder The price will be different: 1 Epoxy red lead antirust paint (including 70% red lead powder) 25 yuan / kg 2 Epoxy red lead antirust paint (including 30% red lead powder) 19 yuan / kg What color of red lead antirust paint is generally orange Nowadays, people pay more attention to lead poisoning In order to meet the national requirements of environmental protection, red lead antirust paint is gradually replaced by other antirust primer with balanced performance But for example, railway steel bridge, industrial pipeline and important mechanical equipment are generally permanent important steel structures, so the red lead antirust primer is still widely used in this field in China, and it is still irreplaceable in some fields It is worth noting that there are two types of red lead antirust paint, one is red lead phenolic antirust paint, the other is red lead alkyd antirust paint However, the content of red lead in non-volatile matter of these two types of red lead paint is higher than or equal to 65% The density of red lead antirust paint usually refers to the mass per unit volume of paint under the specified temperature as the paint density, while the density value of antirust paint is mainly determined by the pigment it uses For example, coatings using metal and metal oxides as pigments and fillers are generally of high density, while coatings using organic or inorganic substances as pigments and fillers are of much lower density The materials for red lead antirust paint are modified alkyd resin, red lead antirust agent, constitutional pigment, etc due to the high density of these materials, the density of red lead antirust paint is also high For example, the density of red lead alkyd antirust paint is 1.90g/cm3 Red lead antirust paint construction process 1, can use air spray, can also use brush coating 2 Before use, the base material should be cleaned, without dust, rust and stains before use 3 X-6 alkyd diluent can be used to adjust viscosity 4 When spraying the top coat, if the gloss is too bright, it is necessary to dry the surface of the previous coat or polish it evenly with 120 grit sandpaper before construction 5 When selecting the paint spray gun, the distance from the steel surface shall be 20cm, the diameter of the spray gun shall be adjusted well, and the spraying speed shall be uniform; when selecting the brush, the alkyd diluent shall be added into the alkyd antirust paint, and the paint brush with good quality shall be evenly stirred, and the brush shall be soft and hard, and the strength shall be uniform when applying on the object surface After the first spraying, the second spraying can only be carried out at an interval of about 30 minutes The second spraying can increase the thickness of the paint film and improve the effect of rust prevention Red lead antirust paint component red lead antirust paint is a mixture of red lead and dry oil, and its main component is red lead naturally The chemical name of red lead is lead tetroxide, also known as lead lead, which is bright red or orange red powder Red lead has a strong antiseptic effect and can be used to kill bacteria and parasites The antirust effect of red lead is mainly chemical antirust, that is, through the chemical reaction of lead tetroxide and iron to change the surface properties of iron products to achieve the antirust effect, and the characteristics of the products also have a certain antirust effect 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,
