Identify the three major standards of paint
Xia Yu Chemicals general manager Liao Jiangshui: family decoration can not be separated from the paint, and in the current market, almost all paint manufacturers say that their products are of good quality, but the actual situation is that some products not only have strange taste after use, but also cracking , from the skin, there are mold. In my opinion, there are three major criteria for measuring the quality of coatings:
The first thing to look at is the basic function of the paint. As an ornament, the most important thing is to pass through its decorative function, that is, no cracking after use, no skin, no fall off, waterproof and light resistance, pollution resistance, anti-mildew and anti-bacterial. After the paint is used, it is hard and wear-resistant, and the poor paint will soon appear peeling and cracking.
Second, we must pay attention to the safety and environmental performance of paint. Consumers can't just listen to advertisements, but must pay close attention to the results of spot checks conducted by the national authorities. At the same time, they must look at whether the environmental protection inspection agencies that the manufacturers said are approved by the National Bureau of Technical Supervision and have CMA inspection marks. Because the test results of those small testing stations that have not been approved by the State and do not have the CMA mark are simply not credible.
The last is the cost-effectiveness of the coating. Naturally, consumers must also consider whether or not they want to pay for the paint. After satisfying the above two principles, they will be truly accepted by people.
Green paint to distinguish true and false
Jiabaoli Group Xiamen Service Center, Xiamen Chendewei Chemical Enterprise Co., Ltd. Chen Chaowei (engineer): In recent years, with the deepening of people's health consumption, green has become a major standard for consumers to purchase building materials. However, a closer look at large and small barrels of paint, it is not difficult to find "green paint", "natural paint", "green paint" a wide variety, so that consumers know what to do. In fact, a considerable part of "green building materials" is full of indiscriminate use, and some are "greening." Since the National Standard for Coatings was enforced on July 1 last year, almost all coating companies have said that they are producing green products, and their basis is "national standard." In fact, "national standard" is not the same as "green." National standards are just the standards for the access of interior decoration materials to the market. If they fail to meet this standard, they will not be eligible to enter the market. The requirements for green products are even higher. Only the China Environmental Labelling Product Certification Committee issues the “Ten Ringsâ€. "The products of the logo can be called "green products."
In view of this, consumers should carefully screen when choosing qualified coatings. First of all, when buying, it is necessary to choose a regular sales operation shop, choose a product from a well-known manufacturer, and see if the coating meets the national mandatory standards. Second, we must carefully review the product quality inspection report, especially the VOC (Volatile Organic Compound Abbreviation) content on the quality inspection report. In the national standard, the VOC limit is no more than 200 grams per liter, the better coating is less than 100 grams per liter, and the environmental protection coating is close to zero. Third, if possible, ask the seller to open the paint bucket and test it personally. If there is a serious stratification phenomenon, indicating poor quality; with a stick gently stirred, lifted, the paint stays on the stick for a longer time, covering evenly, indicating that the quality is good; hand rub a little, wait until dry, use Clear water is hard to wash away; hand light, the more delicate the better. Non-environmentally friendly paints, because VOC, formaldehyde and other harmful substances exceed the standard, most of them have irritating odors, then the choice should be cautious. Of course, do not buy products that smell very fragrant. In general, these types of paints have added flavors. The additives themselves are chemical products and it is difficult to ensure environmental protection.
Choose paint with tips
Hualong Coatings Fujian Service Center Chen Zailai: Paint is an important final link in the home improvement. Low-grade, poor-quality paint has uneven luster, yellowish brittleness, cracking, and peeling. It not only wastes high-quality plates, but also destroys the overall decoration effect. High-quality paint can not only make up for the defects of the pre-decoration, but also can improve the quality and grade of the entire decoration, giving the home a richer cultivation and connotation. However, there is no obvious difference in the appearance of the paint. In the absence of professional equipment, it is not easy to choose. Here are some of the simplest options.
The most important thing is to buy the packaging: lift the paint bucket and shake it. If there is a crackling sound, it means that the packaging is seriously lacking, and there are two shortages, and the viscosity is too low. The formal factory is really real and can hardly hear the sound. .
Buying the least amount of consumption: Consult the merchant for the number of painting passes and the area for painting, the amount of calculation and the cost per square meter of the material, not deceived by the unit price of each group (barrel), the paint from the solids (film forming) And the composition of volatiles, high solids content of 70% to 80%, low of less than 10% to 20%, the unit is often very large consumption of large, more expensive and more cost-effective to calculate, and poor quality.
Buy professional and strong support: good quality products are often more professional, according to the plate texture, color, structure or use of objects with different designs and strict process requirements, and provide technical guidance and after-sales service, regular manufacturers are Provide colorful color model card.
If a qualified product inspection report is purchased, any report with the word “consignment inspection†is not credible, because the product submitted must be qualified, but the product it sells is not necessarily; the inspection report marked “supervisory inspection†has Credibility.
Buying leading products: The degree of best-selling merchandise, whether it is the leading product, and whether it can be inferred from the prominent position of the shelf or the size of the furnishings.
Pay attention to the use of area and weight units in the theory of coating: Some theoretical areas are only painted once, and you must make sure that you have a surplus when buying. Different paints use different units. Some use kilograms, others use liters, some use gallons, and others use buckets. It is best not to buy them in barrels because the quality and quantity inside are different. It is prone to error.
In addition, we must carefully observe the iron bucket there is no corrosion, leakage phenomenon; pay attention to the clear signs on the barrel is complete; for imported coatings, it is best to choose a product with Chinese signs and instructions; see the paint production date and Shelf life, expired paint can not be purchased, otherwise endless trouble.
