    Nowadays, both environmental protection and beauty are almost the same pursuit of the 80's and 90's decoration, and the purchase of materials is the first barrier of decoration, especially the most widely used paint and coating, which directly affects the visual effect of decoration

    So, how can we choose the fitment coating suitable for ourselves? In the daily home decoration, according to the different objects, the paint can be divided into wall paint and wood paint

    At present, most of the well-known paint brands in China, some focus on wall paint, some prefer wood paint, but there are also balanced development brands

    Seaweed mud and children paint in the wall paint, beautiful door and grain paint in the wood paint are more popular products

    According to the different diluent, the paint can be divided into water-based paint and oil-based paint

    Emulsion paint is mainly water-based paint, while nitrocellulose paint and polyurethane paint are mostly oil-based paint

    The wall is painted with water-based emulsion paint, while the wood and metal furniture are painted with oil-based color paint

    The most commonly used in home decoration is wall paint and wood paint

    If you can understand it, you can avoid being cheated and suffering unnecessary losses

    Wood paint includes nitrocellulose paint, polyester paint and more environmentally friendly water-based wood paint

    Polyester paint is a kind of thick paint with polyester resin as the main film-forming material

    Its film is full, the layer is thick and the surface is hard, and there are also varieties of varnish

    Curing is required during the construction of polyester paint

    The content of curing agent is about one third of the total amount of paint, and the main component is TDI (toluene diisocyanate)

    TDI in the free state will turn yellow, which will not only make the furniture paint surface turn yellow, but also affect the adjacent walls, which is a major disadvantage of polyester paint

    At present, yellow resistant polyester paint has appeared on the market, but it can only cure the symptoms, not the root, and can not eradicate the Yellow transformation

    In addition, free TDI beyond the standard will also cause harm to the human body

    Long term inhalation will stimulate the human body, causing pain and tears, conjunctival congestion, cough and chest distress, asthma, red papule, maculopapular rash, contact allergic dermatitis and other symptoms

    The international limit standard for free TDI is below 0.5%

    Please read the instructions carefully when purchasing

    Nitrovarnish: also known as clear spray paint, it is characterized by fast drying, hardness, brightness, wear resistance and durability

    It is a high-grade paint, suitable for painting and decoration of wood and metal surfaces, as well as for high-grade doors and windows, plate walls and handrails

    The main blending auxiliaries of nitrolacquer are Tianna water and whitened water

    These substances contain organic solvent mixtures such as esters, alcohols, benzene, ketones, etc., which mainly play the role of blending and curing nitrolacquer, and can eliminate the whitening phenomenon of paint surface

    However, its volatile harmful substances are very harmful to human body

    After decoration, ventilation should be done frequently to avoid residual in indoor air

    Water based paint: take water-soluble resin as film-forming substance and water as solvent

    Suitable for wooden furniture doors and windows, walls and ceilings

    High grade latex paint products should be healthy and environmental protection products

    Water based paint does not contain benzene, toluene, xylene, formaldehyde, free TDI toxic heavy metals, non-toxic and non irritating smell, harmless to human body, not polluting the environment, and resistant to yellowing, fast drying and easy to use

    Waterborne paint is still in the initial stage of development in China, but the market response is good

    Carpoly is the leading brand of waterborne paint in China, and it has the largest production base of waterborne paint in Asia

    Interior wall wall paint: latex paint is generally the main, that is, emulsion paint, according to the different substrates, can be divided into polyvinyl acetate emulsion and acrylic emulsion two main categories

    With water as diluent, latex paint is a kind of paint product with convenient construction, safety, water washing resistance and good air permeability

    It can also be made into different colors according to different needs

    Latex paint is made up of water, pigment, emulsion, filler and various auxiliaries

    It is more environmentally-friendly, but there are still illegal manufacturers in the market using inferior water-soluble paints to fake latex paint

    Understanding the basic knowledge of coatings is only the first step

    How to avoid buying fake and inferior coatings? Paint and coating is the last part of decoration, and also the most intuitive embodiment of the decoration effect of the room

    The low-grade and poor quality paint has uneven luster and is prone to yellowing, embrittlement, cracking and peeling

    It not only wastes high-quality boards, but also pollutes the indoor environment and destroys the overall decoration effect

    High quality paint can not only make up for the defects of early decoration, but also improve the grade and grade of decoration

    However, there is no obvious difference in the appearance of the paint

    How to choose it? Here are some of the easiest ways to choose

    1

    Look at brand strength

    With high brand awareness, good reputation, stable product environmental protection quality, and guaranteed by large enterprises

    For example, Carpoly, the largest private paint brand in China, has a good reputation in terms of product quality and service

    2

    Look at the weight of the product

    Lift up the paint bucket and shake it for a while

    If there is a crash, it means that the package is seriously insufficient, lacking weight and viscosity is too low, and the real product can hardly hear the sound

    3

    Look at the supporting materials of the product

    Good products are more professional, not only have strict process requirements, but also design different sample styles and color cards according to the texture, color, structure or using objects of the board, and provide technical guidance and after-sales service

    4

    Look at the packaging of the product

    Whether the external package marks are complete, and whether the main components, environmental specifications, certificates and manufacturers of the products are clearly stated

    Paint is one of the important pollution sources

    The appearance of green paint is undoubtedly the guarantee of health

    The so-called green coating, which can protect the environment, has the characteristics of non-toxic and no peculiar smell, and can inhibit the growth of mold at the same time

    When choosing paint, how to identify whether it is green paint? First of all, to buy green paint, we need to choose famous brands, to purchase in regular stores, and then to see whether the products meet the relevant national environmental protection standards

    Secondly, carefully read the quality inspection report of the product, especially the VOC content in the quality inspection report

    According to the national standard, the VOC content is not more than 200g per liter, the better coating is less than 100g per liter, and the environmental protection coating is close to 0

    If you can ask the dealer for permission, you can let him open the paint barrel and test it himself

    If serious stratification occurs, the quality is poor

    Stir gently with the stick

    After lifting, the paint will stay on the stick for a long time and cover evenly, indicating that the quality is better

    Twist lightly with the hand, the more delicate, the better

    In addition, due to VOC, formaldehyde and other harmful substances exceeding the standard, most of the unqualified coatings have pungent smell, which is harmful

    Therefore, we must carefully choose the brand coating with quality assurance and technical services
