Because of the different emulsion used, the names of interior wall latex paint are different, such as acrylic interior wall latex paint, styrene-acrylic interior wall latex paint, vinyl acetate interior wall latex paint and so on. Because the main components of interior wall latex paint are obviously different from water-soluble coatings, the coating properties after film formation are also quite different. As far as the comprehensive performance of latex paint sold in the domestic market is concerned, it is obviously superior to water-soluble interior wall paint.
With the help of specific construction methods, the interior wall latex paint can be painted on the surface of the building, which can form a continuous film with strong adhesion and play a decorative and protective role for the building. In recent years, among many decorative materials, interior wall latex paint has gradually replaced wallpaper and wall covering to win the favor of consumers and become one of the main materials for home decoration because of its rich colors, natural and elegant decorative effect, convenient construction, easy renovation, fast drying, scrub resistance, safety and non-toxicity.
With the rapid development of China's construction industry, architectural decoration has entered a new development period. According to the statistics of relevant departments, the annual output of architectural coatings has reached 6.5438+0.5 million tons, of which interior wall coatings account for about 55%.
Faced with a variety of interior wall latex paints with various names, different prices and exquisite packaging in the market, how can consumers buy products with moderate prices and good comprehensive performance? Generally speaking, the following points should be paid attention to when purchasing interior wall latex paint:
1. According to its own economic strength, determine the performance, decorative effect and price requirements of indoor latex paint, and then make a choice. At present, both foreign brands and domestic products on the market are generally series products. The comparability of price and quality between products produced by different brands and enterprises is poor, but the higher the price, the better the quality of products produced by the same enterprise. Compared with domestic products, foreign brands have relatively high prices, little difference in product performance, and the decorative effect is often better than domestic products.
2. Try to buy products from well-known domestic or local enterprises or brands. At present, there are many enterprises producing interior wall latex paint in China, including wholly-owned enterprises, joint ventures, state-owned and joint-stock enterprises, private and individual enterprises. Because the technical strength, quality management level and product quality control ability of these enterprises are very different, the product quality is greatly affected. Relatively speaking, the product quality of well-known enterprises and brands at home and abroad is relatively stable.
3. Distinguish authenticity by price, and beware of being fooled. From the production cost analysis of interior wall latex paint in China, the lowest price of interior wall latex paint should be 4 ~ 5 yuan/kg. The products marked "latex paint" on the market, but the price is only 1 ~ 2 yuan/kg, are actually water-soluble interior wall coatings, and their product quality is quite different from latex paint.
4. Pay attention to the production date and shelf life of the product. The effective storage period of interior wall latex paint is generally 1 year. When buying, you can open the lid and observe that the latex paint should be in a delicate and uniform state, and there should be no precipitation, caking, floating water, mildew, odor and other phenomena.
5. Judging the product quality from the express description of the product. At least the following items should be marked on the packaging barrel of latex paint: product model, name, batch number, standard number, weight, manufacturer and production date. Consumers should pay attention to the existence of the above-mentioned express signs when purchasing. In addition, we can know the quality of products from the identification of standard numbers. If the standard number is JC/T? 423-9 1 ",the product should be water-soluble interior wall coating: if the standard number is" GB/T? 9756-200 1 ",the product should be interior wall latex paint and meet the requirements of national standards; If the standard number is q/Q/××× years × months × days × months × days × months × days × months × days × months × days × months × days × months × days × months × days × days × months × days × months × days × days × months × days × days × days × days × months × days × days × days × days × days × months × days × days × days × months × days × days × 18582-200 1 interior decoration materials? The safety index in the limit of harmful substances in interior wall coatings can be obtained from the operator at the time of purchase.
In short, when buying, read more, ask more and pay more attention. I believe that you will be able to choose a satisfactory interior latex paint to make your room shine. (Feng Shifang, executive deputy director and senior engineer of National Coatings Quality Supervision and Inspection Center)?
