Buy the market through comparison test
The most important environmental index of latex paint is the content of volatile organic compounds (VOCs). According to national standards, the VOC content per liter of latex paint cannot exceed 200 grams. In order to facilitate consumers to purchase latex paint, the Consumers Association of China has recently conducted a comparative test of 83 kinds of interior latex paint products in cooperation with the associations of Beijing, Shanghai, Guangdong, and Sichuan.
Brand paint more environmentally friendly
According to the results released, the environmental performance of the latex paint basically met the standard. The contents of volatile organic compounds (VOC) and soluble heavy metals in all samples were in compliance with national standards; only one sample of formaldehyde exceeded the upper limit of the national standard. Because the 83 samples used in the experiment were purchased from 19 building materials markets or supermarkets in four cities of Beijing, Shanghai, Chengdu, and Guangzhou, they covered major international and domestic brands and local brands, as well as products with different prices for the same brand. Therefore, consumers who pay attention to environmental protection can give priority to purchasing branded latex paints.
Special reminder: When buying latex paint, you should go to the reputable building materials market. The majority of mainstream branded products on the market for regular building materials meet the national standards for environmental performance.
The higher the price is not better
The price issue that consumers care about, according to test results, shows that the higher the price, the better the performance index. The price of latex paint on the market is quite different. The prices of 83 samples per liter range from 7 yuan to 117 yuan. Compared with the sample with the highest price of 117 yuan per litre and the sample of 63.5 yuan per litre, there are no major differences in the test results of environmental performance, hiding power, stain resistance, and mold resistance. However, the two products with large differences in unit prices also have advantages and disadvantages in comparison of performance indicators.
Special reminder: In the purchase of such products, should be a good value for money as a purchase standard. Consumers should choose the latex paint with the corresponding characteristics according to the different functions of the room. Such as the bathroom, basement, the best choice for better mold resistance, kitchen, bathroom selection of stain resistance and scrub resistance better products; choose a certain degree of elastic latex paint, cracks on the cover, to protect the wall decoration effect; Choose your own multifunctional product.
In addition, it has also been found through inspection that due to the very close relationship between various performances of the coating products, and even mutual restriction, the single performance may not be outstanding for the multifunctional products popular in the market, but the overall performance is generally better.

1. Features of tape measure
Gift rulers are used for advertising and promotion. They are divided into Steel tape (steel tape) and leather tape (PVC plastic fiber tape). They are usually cute and compact. Tape measures are also called measuring tools. Eighty-five percent of the world's tape measures are exported from China.
2, the characteristics of the tape measure
(1) The tape measure is too deformed and will not fail
Why didn't it fail? The spring in the tape measure is very long, and its range from completely relaxed to fully tightened is very large. The entire stroke of the tape measure includes it, and there is a margin at both ends, so the tape measure will not fail.
(2) Pull one meter long and pull two meters long, there is no difference in tension
The spring of the tape measure is very thin, and the amount of deformation when it is tightened is also small, so the reaction force is very small, and the force change is not felt when the rule is pulled.
