Three major problems in the paint market
The current coating problems are:
First, poor quality and performance of medium and low-grade products. The national standard stipulates that the scrubbing resistance index is not less than 200 times. The reason for the product non-conformity is that the company cut corners and materials, uses raw materials with poor quality, and does not strictly carry out inspections.
Second, the quality of products of small companies is unstable. Due to the small scale of production of enterprises, limited investment in technological transformation and technological development, relatively backward production processes, weak corporate management, incomplete quality management systems, and poor product quality stability. Among these enterprises, there are still some companies, ranging from a few people to as many as a dozen people. The factory buildings are poorly equipped, technical strength is weak, and the quality of personnel is low. They do not have inspection methods, let alone quality control, and production has some blindness. Although these enterprises have limited output, they have flooded the market with low-grade, low-quality, low-price, and even fake and shoddy products, resulting in low price competition and similar competition in the market.
The third is that the implementation of standards is not strict, and the inspection and control ability is poor. Some companies do not carry out product batch inspections or do not perform ex-factory inspections in accordance with the express standards, reflecting the company's low level of quality management and the lack of attention to product inspections.
Three types of interior wall paint
One is the low-grade water-soluble paint. Polyvinyl alcohol is dissolved in water and added with other additives such as pigments. The disadvantage of this coating is that it is not water-resistant and alkali-resistant, and the coating is easily peeled off after being exposed to moisture. It is a low-grade interior wall coating, and is mostly used for interior and interior decoration of middle and low-end living rooms or temporary residences.
The second type is latex paint. It is a water-based medium, and the water resistance and weather resistance of aqueous solutions of acrylic esters, styrene-acrylic ester copolymers, and vinyl acetate polymers are greatly improved compared to the first type, and no traces are left after wet scrubbing. There are different types of decoration, such as flat light and high light, which belong to middle-grade paints. Although the price is more expensive, due to its excellent performance and decorative effect, it occupies an increasing market share.
The third category is the colorful paint that is currently very popular. The film-forming substance of the coating is nitrocellulose, which is dispersed in the water phase in the form of oil-in-water, and can be formed in multiple colors by one spray.
The outer wall paint brush inner wall, no problem from the environmental point of view, and the inner wall paint used to brush the outer wall is not necessarily OK.
Inner and outer wall latex paints have their own special requirements. The outer wall latex paint is used to paint the building facades. Therefore, one of the most important indicators is anti-ultraviolet radiation. Interior wall paints are used for interior wall paints, and UV resistance is much lower than exterior paints. The interior wall latex paint has high requirements on scrub resistance, and it is easier to contaminate the wall in home life and can be wiped with water at any time.
External wall paint can be used for interior wall brushing because it also has water resistance, while interior wall paint does not have anti-sun function, so it can not be used to paint the exterior wall, but experts suggest that it is still special for special purposes.
How to identify green paintThe so-called green paint is able to protect the environment, has the characteristics of non-toxic, no smell, can inhibit the growth of mold. So, how to identify green paint?
First of all, when purchasing paint, you must choose a formal sales operation shop and choose a well-known product to see if it meets the national mandatory standards.
Second, we must carefully review the product quality inspection report, especially the VOC content on the quality inspection report. National standards require that the VOC limit be no more than 200 grams per litre, better than 100 grams per liter of paint, and environmental protection coatings close to zero.
If possible, ask the seller to open the paint bucket and test it in person. If there is serious stratification, it indicates poor quality. After gently stirring with a stick, the paint stays on the stick for a long time and covers evenly, which means that the quality is better. The lighter the hand, the finer the better. Fuk Lok House, the master's interior latex paint on the open cover sales, allowing consumers to intuitively feel its unique environmental protection.
Construction rules determine wall quality
Construction should pay attention to what? Before the construction of latex paint, the wall surface must be handled well. Otherwise, the emulsion paint will cause serious problems such as shedding, cracking and foaming. Therefore, when using latex paint, first use the back cover to seal the wall surface, and then use water-resistant putty to avoid the above problems.
When applying latex paint, mix it evenly, especially when using colorful products.
In addition, the construction of latex paint can add water and the amount of water, must be in strict accordance with the provisions of the manufacturers.
In addition, brushing, roller coating and spray coating processes can be applied during construction. Either of the above methods can achieve the desired results, but the viscosity of the latex paint needs to be adjusted so that it can be easily applied during construction and it is not noticeable after brushing. Brush marks are appropriate.
