Common sense of the choice of home decoration coatings and the inevitable trend of the selection of nano ceramic coatings

1. What is the primary consideration in choosing paint?

Environmental protection Coatings are widely used in daily life for wall decoration. VOC content of volatile organic compounds in coatings is an important index to measure environmental protection level. Formaldehyde is a kind of VOC. Formaldehyde, benzene and other harmful substances in VOC will be continuously released unconsciously. When indoor VOC content reaches a certain concentration, it will cause headache, nausea, vomiting, fatigue and other symptoms, and even convulsions and coma in severe cases, damage to the liver, kidneys, brain and nervous system, causing memory loss and other serious consequences. The harm to the human body is huge and long-term, and is usually described as a new killer of human health. So when buying paint, be sure to look at the environmental protection mark and VOC, formaldehyde content,The lower the VOC content, the higher the environmental protection index.

2: no smell of paint must be healthy?

not necessarily oh The real environmental protection paint should be water-based, non-toxic and tasteless, so when you smell the pungent smell or the smell of industrial essence, it must not be environmental protection paint, and you must give up decisively. Some bad merchants use the smell of essence to cover up the pungent smell of the paint and disguise themselves as net smell products. Let the owners in the purchase of the time can not smell the smell, so tasteless products are not completely environmentally friendly non-toxic.

The real environmental protection coating how to do tasteless?Regular big brand manufacturers, under the premise of ensuring the quality of coatings, try to reduce the content of harmful substances in raw materials, so that it is lower than the national environmental protection standards for coatings, which is the real reason why coatings do not contain pungent taste. So in the purchase of paint, in addition to smell, but also to see the other aspects of the indicators.

3: how to identify the business of false propaganda?

Identification test report Regular manufacturers will have product inspection reports issued by third-party inspection agencies. When purchasing, do not trust the publicity of the merchants. You must recognize the quality inspection reports, such as ISO management system certification. The VOC label represents the mark with the highest environmental protection level-France A certification. Affected by the epidemic, functional coating products such as antibacterial and antiviral are currently sought after by the public in the market, be sure to check the relevant antiviral and antibacterial certification in order to avoid buying products that are not on the right board and make up the number.

4: the dazzling array of functional products should be how to choose?

Stain resistance some paint in film after being water erosion, make metope moldy, peeling, long-term accumulation of dust, such as handprint shoes will make the metope become dirty... when the metope is dirty after, how to clean is a headache. A paint with good stain resistance will make it easier to take care of wall stains. Whether the stain resistance is strong or not depends on the scrub resistance of the paint.

Cleaning the wall surface means repeated washing. Low-quality water-soluble paint will fade when it is wiped dozens of times. Wall surface repair is difficult and consumables are laborious. At present, the strongest washing resistance of interior wall paint can reach 100,000 times without leaking the bottom. Choosing paint with high abrasion resistance will make your life cleaner and more worry-free!

Water resistance and mildew resistanceFor humid areas in the south, the wall often see black mildew, in addition to visually unbearable, the most terrible thing is that mold will continue to release mold spores into the air, mold spores exceed the standard and even more terrible than formaldehyde. Scientific research shows that 10% of asthma diseases are caused by mold, especially asthma in children.

Want to stay away from mold, it is necessary to put an end to its growth from the root. Therefore, in the choice of paint to choose inorganic paint rather than organic latex paint, inorganic paint is a natural inorganic mineral paint, not mixed with organic glue substances, no mold breeding needs nutrients, in addition, inorganic paint water permeability, but also to solve the wall damp condensation and other problems, can not reach the conditions of mold breeding, so as to inhibit mold. Water resistant mildew preferred inorganic coatings!

Remove odorRemove odor function of wall paint, can be decomposed to remove ammonia, hydrogen sulfide and other odor, especially suitable for household, public bathroom and other special areas, the kitchen produce foul smell garbage also has a good dispelling effect. Improve the quality of life!

Fire PreventionPaint and other coatings do not seem to be very powerful, but they are also flammable. The winter decoration weather is dry. Once an open flame detonates the paint, the consequences will be disastrous. Can buy a class a fire retardant coating, to ensure home safety.

5: paint model to see what?

Template making Usually good quality paint, after brushing has a relatively high hardness, in the purchase, you can slide back and forth on the surface of the paint sample, to see if the surface of the sample is worn, if the surface scratches, then the quality of the material is not good. In addition, you can also observe the color, process, hiding power, quality, etc. of the paint through the paint model.

In view of the above knowledge of choosing home decoration coatings, what kind of coatings should we choose to take into account these characteristics-nano ceramic coatings. First of all, let's take a look at what is nano-ceramic coatings and their functional properties.

1:Nano-ceramic coating is a kind of multi-functional composite coating composed of modified ceramic materials and nano-materials, which has remarkable heat insulation effect and excellent corrosion resistance. With the addition of nano materials, the adhesion, density, strength and other properties of the paint film are greatly improved, so that the traditional paint "old appearance", more functions, more stable efficacy.

2: nano ceramic coating classification:

Architectural coatings (interior wall coatings, exterior wall coatings), anti-corrosion, wear-resistant coatings, high temperature, anti-corrosion, insulation "three-in-one" coatings, insulation, hydrophobic waterproof coatings.

3:Characteristics of nano-ceramic coatings

Nano composite ceramic coating is water as solvent or solvent-free, non-toxic, tasteless, VOC is zero, is completely environmentally friendly products, by domestic and foreign users of great attention and wide application, has been FAD certification and SGS certification.

Nano ceramic coating for wear parts

This kind of nano-coating is based on nano-inorganic ceramic materials as the main raw material, has a strong penetration, through the proprietary special synthesis technology to make it has excellent film-forming. By spraying, wetting or coating, the nano inorganic ceramic material is infiltrated into the substrate to form a nano ceramic surface protective layer, showing excellent functionality. It has the following characteristics:

(1) High-density sealing and corrosion resistance: Due to the stable, fine and high fluidity, leveling and permeability of nano-inorganic ceramic materials, it can be applied to almost all kinds of material surfaces and fill pinholes and blind holes on the surface to achieve high-density sealing and corrosion resistance, with excellent weather resistance.

(2) Excellent waterproof, hydrophobic, oleophobic and anti-fouling self-cleaning properties: due to the nano-surface effect and its interface characteristics, the surface of the processed object has nano-lotus effect, so that water, oil and other liquids are suspended on the surface nano-bumps with high tension and quickly discharged from the surface, thus reducing the chance and time for liquid substances to reside on the surface and achieving excellent waterproof, hydrophobic and oleophobic properties. At the same time, the dust retained on the surface can be taken away to show the anti-fouling self-cleaning property.

(3) high hardness and high wear resistance: the nano inorganic ceramic protective coating is composed of high stable state nano inorganic oxide ceramic material, the nano material itself is very high hardness (micro hardness of about HV400-600). After the film is formed, the relative density is very high, the overall surface hardness is about 6H or more (Pencil hardness is more than 6H),(the hardness of the coating for general commercial and industrial use is about 2H), and its wear resistance is outstanding due to its high density characteristics.

(4) high temperature resistance: nano inorganic oxide ceramic material its destruction temperature is about 800-980 ℃, the temperature resistance after film formation is about 400-800 ℃.

(5) Antistatic: Because the nano inorganic oxide ceramic material is a high dielectric material, it has good antistatic properties.

(6) UV resistance: This kind of nano inorganic ceramic material is a kind of ultraviolet absorption material, solid has good UV resistance.

(7) Good function expansion performance: Because the material is stable and not easy to change, it can be filled with nano materials with other functional requirements to expand the function. (such as anti-electromagnetic wave, antibacterial, anti-mold, etc.)

Applied to the surface of metal or metal coating, this nano-thin layer can prevent surface oxidation, insulation, antistatic, waterproof, dustproof, high hardness, wear resistance and non-stick self-cleaning effect.
