The characteristics of water based anticorrosive paint are mainly reflected in what places

Anticorrosive wood is the ordinary wood after artificially adding chemical preservatives, so that it has the characteristics of anti-corrosion, moisture-proof, fungal-proof, anti-insect ants, mildew and waterproof, etc., can directly contact the soil and humid environment, often used in outdoor flooring, engineering, landscape, anti-corrosive wood trellis, etc., for people to rest and enjoy the natural beauty, is an ideal material for outdoor flooring, garden landscape, wooden swings, entertainment facilities, wooden plank roads, etc., favored by horticultural designers, but with the development of science and technology, Antiseptic wood has been very environmentally friendly, so it is often used in interior decoration, flooring and furniture, and interior decoration designers also like antiseptic wood very much. There is also a kind of preservative wood without preservatives - deep carbonized wood, also known as heat-treated wood. Carbonized wood is the effective nutrient of the wood is carbonized, and the decaying bacteria survive by cutting off....

Because many people don't know much about anticorrosive coatings, especially in terms of its functional characteristics. What are the characteristics of anticorrosive coatings? PChouse will take you to find out.

1. Strong function.

It can be used under harsh conditions and has a long-term anti-corrosion life, and the heavy anti-corrosion coating can generally be used for more than 10 or 15 years in the chemical atmosphere and marine environment, even in acid, alkali, salt and solvent media, and under certain temperature conditions, it can be used for more than 5 years.

2. Strong adhesion.

The coating has a strong binding force to the substrate, the coating composition contains a hydroxyl group (-OH), and the metal matrix provides positive ions, which can form chemical bonds, and even achieve the binding of covalent chains with the help of coupling agents in the coating. Under the maintenance of the spatial network structure, the metal, metal oxide nanomaterials and rare earth oxide ultrafine powders contained in the coating composition help the coating form a dense interface transition layer, so that its comprehensive thermodynamic properties match the matrix.

3. Efficient and convenient.

When the ambient temperature is 20 and the relative humidity is less than 85%, the surface is dry for 15min and the dry is 2h, which can ensure high-efficiency construction, and can achieve excellent anti-salt spray and anti-aging. The coating is self-repairing, local scratches caused by external force can still be protected, the coating is not damaged by cutting and welding, and welding with coating does not affect the welding quality.

The anti-corrosion principle of anti-corrosive paint forms an insulating coating on the surface to be coated, preventing air from coming into contact with it. Anticorrosive paints are used to protect metals from corrosion, and are generally used in harsh environments, and they include primers and lacquer finishes. Some friends may not know much about anticorrosive paint, but it doesn't matter, today I will take you to understand its characteristics and coating process.

Characteristics of anti-or row stool corrosion paint.

Anticorrosive paints can be used in harsh environments, and have good durability and weather resistance, can be maintained under harsh conditions for more than 10 to 15 years, even in acid, alkali and salt media, and under special temperature conditions, can be used for more than 6 years.

Coating process. The environment in which it is applied should be in accordance with the regulations of the Instruction Manual. In case of climatic conditions such as fog, snow and rain, the open-air work of anticorrosive paint should be suspended immediately.

When the ambient temperature is less than -5 or greater than 35, or the relative humidity is greater than 75%, it is not suitable for operation. The anticorrosive paint surface that has not solidified should also be protected from rain erosion.

Before the first primer, after the surface pretreatment, if there is rust, the rusty part must be treated.

The coating method used by the belt picker is not a fixed one, but a more anti-corrosion construction scheme to determine, and the following provisions should be met when coating:

a. When using the brushing method, it should be evenly coated and brushed in the same direction to avoid unnecessary fluffing on the surface.

b. If spraying, the spray gun should keep the speed uniform when working, and let the nozzle be perpendicular to the sprayed surface.

c. If it is a roller coating method, the roller should be evenly applied, the amount should be appropriate, and the force should be moderate when rolling, and the uniform speed should be applied; The drum should be rolled in the same direction, and it is okay to have a different direction each time. For the corners and parts where the roller cannot be constructed, a brush tool should be used to repaint. On uneven surfaces, it is recommended to dip more paint and increase the number of applications.

Anticorrosive paint can extend the life of metal, can adapt to harsh environments, and it is also a relatively common functional paint. Do you know more about anticorrosive paints now? I want to know.

Water-based paints are paints that use water as a thinner and do not contain organic solvents. There are three types of water-based paints: water-soluble paints, water-diluble paints, and water-dispersible paints (latex paints). Water-soluble paint is made of water-soluble resin as a film-forming substance, represented by polyvinyl alcohol and its various modifiers, in addition to water-soluble alkyd resin, water-soluble epoxy resin and inorganic polymer water-based resin.

Advantages of water-based paints.

1. Use water as a solvent to save a lot of resources; Eliminates the risk of fire during construction; Reduced pollution to the atmosphere; Only a small amount of low-toxicity alcohol ether organic solvents are used, which greatly improves the environmental pollution caused by other paints.

2. Water-based paint can be directly coated on wet surfaces and humid environments; It has good adaptability to the surface of the material and strong adhesion of the coating.

3. The coating tool is easy to clean, and it can be washed off with water, which greatly reduces the consumption of cleaning solvent and is harmless to the human body.

4. It does not contain harmful carcinogens, is non-toxic and tasteless, because it does not contain harmful substances, it will not volatilize into the air, so it will not have defects such as easy yellowing, and it will last as long as new.

Deficiencies. The biggest disadvantage of water-based paint is that it is not a solvent volatile product, and the drying speed is greatly related to temperature and humidity, so the drying time is slightly longer than that of traditional paint. During construction, it is necessary to apply thin and scrape, because the solid composition of water-based wood paint is relatively high, and the viscosity of brushing is relatively low, as long as a thin layer of paint film is brushed, there is a certain thickness. When painting, it is easy to sag, so the painter is required to brush and paint thinly during the construction of water-based wood paint.

Water-based paint is completely environmentally friendly and pollution-free, emission reduction, low-carbon and environmental protection, in the current situation of people's increasing pursuit of healthy life, the health of water-based paint is becoming more and more important. Water-based paint is easy to apply because the main material has water, and the remaining materials can also be stored for a long time, which reflects the characteristics of environmental protection and pollution-free.

Water-based paint is water as a thinner, is a pure green environmental protection coating, now the range of use is more and more wide, like furniture, home decoration, industry, metal have been used to water-based paint, like Jinglong water-based paint drying fast, good grinding, good leveling, easy construction, paint film plump, high hardness, good flexibility, water resistance, heat resistance, wear resistance, aging resistance, yellowing resistance, etc. are a major feature of water-based paint.

Water-based paint, I believe many people have not heard of this word, in fact, water-based paint is now very popular, water-based anti-corrosion paint is also one of them. But readers, are you familiar with water-based anticorrosive coatings? In fact, the role of water-based anticorrosive coatings is very good, many consumers are very fond of water-based anticorrosive coatings, and water-based anticorrosive coatings have many good characteristics.

Next, let's get to know each other together. So, what are the characteristics of water-based anticorrosive coatings?

Features of water-based anticorrosive coatings

Peculiarity. High solid content and large brushing area; Super anti-corrosion performance, salt spray resistance, solvent resistance, acid and alkali resistance; It is suitable for all kinds of metal substrates, and has strong adhesion; Faster drying and easy construction; Non-toxic, odorless, non-flammable and non-explosive. Reserve.

Store in a cool, dry environment at 5-35 hours in a closed and sealed environment. Please refer to the drum label for the date of manufacture and expiration date.

Introduction to the precautions of water-based anticorrosive coatings

Before the construction of anticorrosive paint, two points must be paid attention to: one is the danger of endangering human health; The second is the danger of **. It is important to understand the safety regulations of the product before applying the paint. For example, Jinnuoxin acrylic engineering primer and Jinnuoxin acrylic engineering topcoat, although there is only a word difference, the function is similar, but in the proportion, use and need to pay attention, once there is an accident, it will endanger human health.

Introduction to the construction method of water-based anticorrosive coatings

Can be used dipping, brushing, spraying method construction, paint should be stirred evenly before painting, if the viscosity is high, you can add an appropriate amount of water, the amount of water should not exceed 10%, should be added while stirring, to ensure that the paint liquid is uniform. Before painting, remove the lime sand, welding slag, oil stain, floating rust and old patent leather on the surface of the workpiece. Ventilation should be maintained during construction, and construction should not be carried out under the condition that the ambient temperature is lower than 5 or the humidity is greater than 70%.

The paint film can be self-drying, or it can be dried at low temperature, the temperature is not less than 5 when self-drying, and the humidity is not more than 70%; When drying, the leveling time is not less than 15 minutes, the baking temperature is not less than 60, and the baking time is not less than 25 minutes. For the second coat, the first pass should be dry, at least 24 hours apart. It is strictly forbidden to mix with other coatings and organic solvents.

At the end of construction, the utensils used should be immediately rinsed with clean water to prevent drying. The remaining paint should be stored in an airtight manner, and if there is dry skin that affects the use, it can be filtered with a 100-mesh wire mesh before use.

Today to introduce to you water-based anticorrosive coatings are so much, I believe you have a certain understanding of water-based anticorrosive coatings, in the choice of water-based anticorrosive coatings, you may wish to consider these methods introduced to you. In fact, the role and characteristics of water-based anticorrosive coatings are very much, many times water-based anticorrosive coatings will be used, but when using water-based anticorrosive coatings, we should also pay attention to it, I hope my introduction can help readers and friends.

We are inseparable from the paint when we decorate the source jujube, and the paint also plays a great role, our exterior wall paint has good decoration and water resistance, and the paint on the exterior wall will often be washed by wind and rain. Therefore, the exterior wall paint coating should have good water resistance. Then let's find outPaints and coatingsWhat are the anti-corrosion characteristics and what are the precautions for wall brushing, I hope that good coatings should be selected when decorating.

1. What are the anti-corrosion characteristics of coatings.

1. Corrosion resistance of coating: it can be used in acid, alkali, salt and other media for a long time, and the anticorrosive coating has been tested to be soaked in 5%-50% sulfuric acid and 5%-10% hydrochloric acid saturated Ca(OH)2 aqueous solution for 1 year, and the paint film has no change, and the paint film has not changed for 2000 hours in the salt spray test, and can be kept intact for more than 3 years under the condition of long-term outdoor direct sunlight.

2. The paint film is hard, good adhesion, no cracks in impact resistance (1c kg), no peeling off of the paint film, no change in the spiral scratch test, no cracking and peeling off in bending resistance (diameter 10mm shaft).

3. Curing film formation at room temperature, it can be used for a long time under harsh conditions (-40 degrees -150 degrees), and the sea area is immersed in the sea hanging piece test for four months, during which the paint film is intact, and there are no seaweed and other plants, and its anti-fouling (no marine organisms) performance is unexpected.

4. The coating can be directly brushed on the substrate of hail dismantling after certain treatment, which saves the anti-corrosion coating material and also saves the brushing workload, so that the work cost is reduced and the project quality is improved.

5. On the basis of certain treatment, the anticorrosive coating brush and scraping coating, the coating film is dense, the closed cell rate reaches 100%, and the paint film has strong corrosion resistance.

Second, what are the precautions for wall painting.

1. Whether it is a new house or an old house, there are many cracks in the wall. Many people struggle to choose a good latex paint to deal with the problem of cracking the wall. Therefore, when we buy, we should pay attention not only to the function of "anti-fraud and cracking" written on it.

We will buy, we must buy quality and quantity.

2. Presumably, everyone will think that it is better to buy well-known brands when purchasing latex paint. Of course, the products of well-known brands do have a certain quality assurance, but we cannot blindly pursue brands. The quality and function of many general brand products and well-known brand products are not much different, but there is a big difference in **.

Reasonable selection of latex paint.

3. Our people are paying more and more attention to physical health, and we not only have to see whether it is a fake, but also worry about decorative pollution. When we think of decorative pollution, we immediately think of wall paints, so choose good materials when choosing paints.

The above is for you to introduce the anti-corrosion characteristics of the paint coating and what are the precautions for wall brush coating, the coating is also an important part of our decoration, so we should choose a good one when purchasing, so that the wall will not crack, and not beautiful.
