Recently, a well-known paint brand fraud case has been very loud. Paint is the most indispensable material in the process of home decoration, but it is indispensable for the owners to buy. It is very tangled when the owner purchases, especially in recent years, the reports of poisonous paints cause people to become sick, and the owners are worried when purchasing paints. . Tian Yanming, senior engineer of the Institute of Plastics and Chemicals of Fujian Provincial Product Quality Inspection Institute, said that the owners do not need to talk about paint discoloration. The paint contains certain unhealthy substances, but as long as it does not exceed the standard, it will not pose a threat to health, so consumers You may wish to learn poison and anti-virus before buying!
Engineers know scientifically about coating ingredients
Paint is a general term for a liquid or solid material that is applied to the surface of an object to form a protective, decorative or special property. With the increasing demand for coatings in society, the danger of coatings has attracted more and more attention. So, how does paint cause harm to the human body?
Coatings can be classified into waterborne coatings, solventborne coatings, solventless coatings and powder coatings. The commonly used paint is actually a solvent-based paint. We often say that VOC (Volatile Organic Compound) is an organic solvent that volatilizes during the drying process of paint. The harmful substances that have serious effects on human health in such organic solvents will Irritating to the eyes and respiratory tract, causing skin irritation, causing headaches, sore throat, fatigue and other symptoms. After the renovation of the new house, people always have to ventilate before they dare to move in and live. They are afraid of the organic solvents that they have refused to disperse for a long time.
In order to improve certain properties of coatings, heavy metals such as lead and chromium introduced in some coatings can cause damage to the central nervous system of the human body, leading to encephalopathy and causing anemia, renal function decline and poisoning of the reproductive system, affecting the physical and intellectual development of infants and young children. .
Tian Yanming said that the standard of "Limited Hazardous Substances in Interior Finishing Materials Interior Wall Coatings" (GB18582-2008) is currently being used: First, the water-based wall putty is added, and the limit value of harmful substances is specified; It is to increase the total control project of benzene, toluene ethylbenzene and xylene, and its total content is ≤300 mg/kg; thirdly, the limit value of volatile organic compounds is greatly reduced, and the VOC content of water-based wall coating is ≤120 g/ l, water-based wall putty VOC content ≤ 15 g / kg.
Tian Yanming suggested that consumers should choose labels with complete labels when purchasing paints. The commodity mark generally must have the basic contents of the inspection certificate, the name of the product, the name of the factory, the site, the product execution standard, the production license, the mandatory certification, the date of manufacture, the shelf life, the specifications, the model, the net content, and the warning signs.
Guide shopping, check the information, pay attention to anti-counterfeiting security
When purchasing paint, not only anti-virus, but also anti-counterfeiting, brand-name and counterfeiting have always been a common phenomenon in the coatings market. For the anti-counterfeiting of paints, Mr. Wu, the person in charge of the Meiting Meiju Building Materials Department, reminded the owners that the first thing Choosing a well-known paint brand with good reputation, consumers can understand through the various channels that there are many domestic paint brands that are not only well-known, but also highly professional, with high level of environmental protection technology, good reputation and good service. The Internet, home improvement journals, newspapers, TV, and acquaintances are the mainstays.
Second, consumers can also identify the true and false of paint by watching, smelling, and asking.
Look: Most of the dealers in the formal channels use the method of opening and selling. Ask the seller to open the paint bucket, high-quality paint, the surface is usually no floating things, if there are floating things, it may be inferior products or expired products, you need to buy carefully.
Use a stir bar to pick up the paint. If you can see the thick connection clearly, it is a high-quality paint that flows down like a drop.
Look carefully at the quality inspection report of the product, paying particular attention to the VOC (organic volatilization) of the coating. The smaller the VOC, the more environmentally friendly.
Smell: Smell the smell of paint. Non-environmental coatings have high irritating odors due to high levels of harmful substances such as VOC and formaldehyde. The paint that smells very fragrant is added with fragrance. The additive itself is a chemical product, and it is difficult to ensure environmental protection. Therefore, such products should also be purchased with caution.
Q: Ask the dealer about the number of paints applied and the area of ​​paint per liter, which is not deceived by the unit price. The high-quality coating has a solid content of 90%, a low-cost coating, a low coating rate, a particularly large amount of paint, a higher price, a poor effect, and a very low cost performance.
H Ground Screws also called Screw Piles in some countries and it means Ground Screw Piles with helical blades. There are kinds of Ground Screw piles on our ground screw factory.

As one type of solar screw piles, is very hot product on Finland and Thailand. It also be installed to the ground by Pile Driver as the support of solar panels or solar mounting systems. Screw piles as the related solar energy products are very hot sale products and they are very stable as supporting.
Some types of ground screw we exported can be used to construction field. Ground Screw with Nuts and Ground Screw with Flange, both types of ground screw will be installed if you want to use ground screw in construction field. We produce diameter 114mm-335mm of ground screw and length 1600-4500mm as your choose if you would like to purchase ground screw using to kinds of buildings. If you need these Ground Screw Anchors , please let us know, we will do some plans for you according to your requirements. In addition, Hot dipped Galvanized Ground Screw can not easy to be rust and it can be keep more than 25 years and the material of construction ground screw is Q235/Q235B/Q345 as your need.
