Paint knowledge is waterborne paint more environmentally friendly? Quality index of waterborne paint

Core tip: with the tightening of environmental protection standards in Beijing, Beijing furniture manufacturing enterprises will use water-based Wood Coatings with smaller VOC emissions in a large range through technological innovation in the future, which makes water-based paint once again the focus of consumers The popularity of waterborne paint furniture, in addition to making the atmosphere cleaner, what does it mean for consumers? Experts say that waterborne paint products are indeed more environmentally friendly, but there are certain technical requirements for waterborne paint coating, consumers should pay attention to the technical strength of enterprises and the test report of waterborne paint when purchasing 1 Factory technology affects the quality of paint film consumers can often see the use of water-based paint in the market Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: with the tightening of environmental protection standards in Beijing, the furniture manufacturers in Beijing will use water-based Wood Coatings with smaller VOC emissions in a large range through technological innovation in the future, which makes the water-based paint once again the focus of consumers The popularity of waterborne paint furniture, in addition to making the atmosphere cleaner, what does it mean for consumers? Experts say that waterborne paint products are indeed more environmentally friendly, but there are certain technical requirements for waterborne paint coating, consumers should pay attention to the technical strength of enterprises and the test report of waterborne paint when purchasing 1 Factory technology affects the quality of paint film consumers can often see the furniture that claims to use water-based paint on the market The so-called water-based paint is water-soluble wood paint Unlike solvent based wood paint, it uses water as a blending agent The content of volatile organic compounds and benzene series in the water-soluble paint which meets the national standard are lower than that of the common solvent based wood paint Sun Shudong, assistant director of national furniture and indoor environmental quality supervision and inspection center, said that in fact, no matter solvent paint or water paint, as long as its environmental performance and use performance can meet the requirements of national standards, it can be safely used in the family The VOC release and benzene series release of waterborne paint are indeed small and more environmentally friendly However, the film of water-based paint is thin, many consumers are worried that the adhesion of furniture film after water-based paint finishing is not enough, not resistant to bump Sun Shudong said that, in fact, this largely depends on the manufacturer's technical level and finishing technology In its daily inspection, many water-based paint furniture in the physical and chemical level of the paint film is also very good Therefore, he reminded consumers that when purchasing similar products, they should pay attention to the manufacturer's production capacity and technical strength, because the technical content of the coating itself is very high, and the overall quality of wood paint is only one aspect, and its substrate treatment, grinding technology and so on also affect the final quality of the paint film Another concern for consumers is whether the price of finished furniture will increase significantly due to the use of waterborne paint Qumei furniture water-based paint replacement project is one of the 100 environmental protection and technological transformation projects Zhao Ruihai, chairman of Qumei furniture, said that water-based paint has very high requirements for equipment technology, production environment, temperature and humidity, and seasonal changes At present, its equipment investment alone has reached 20 million yuan, and the growth of direct materials has also increased by 30% Although Qumei said it would not raise the price for the time being, it is bound to need other ways to digest the cost Industry insiders also said that although the production cost of furniture using water-based paint is indeed higher than that using ordinary paint, popularization will not bring too big fluctuation to the overall price of furniture 2 The quality needs to check the test report Can ordinary consumers tell the quality of the water-borne paint film with their naked eyes? Sun Shudong said it's very difficult In furniture testing, the experimenters are talking with the data, "some paint films look really thin, but the test results are qualified." Therefore, when purchasing, you should also ask for the test report related to furniture Water based paint has always claimed environmental protection, how to prove that it can really meet the national standards when purchasing? According to the introduction, the biggest characteristic of water-based paint is the small VOC release and benzene series release, but these two indicators are not involved in the national standard "harmful limit of wood furniture" The standard only regulates the formaldehyde emission of the board and the soluble heavy metal content in the furniture surface color paint The standards of furniture paint film, such as the measurement of resistance to liquid, humidity and heat, adhesion and impact, are also related to the performance of paint film Sun Shudong introduced that in terms of the current detection standard of harmful substances in wood furniture, it is indeed lacking in this regard But the national standard is in the process of revision At that time, the new standard will have clear provisions on VOC release, and use a more scientific climate box detection method in the detection At present, if consumers want to know the above indicators in the paint, they can only rely on the single inspection report of the paint Reporters found that the national mandatory standard "interior decoration" The limit of harmful substances in Waterborne Wood Coatings (gb24410-2009) clearly stipulates that in waterborne wood coatings, the content of benzene series (the sum of benzene, toluene, ethylbenzene and xylene) is 300mg / kg, the content of free formaldehyde is 100mg / kg, and the content of volatile organic compounds is 100g / L consumers can refer to the above values when checking the test report 3 At present, Beijing is vigorously promoting the use of water-soluble wood paint in furniture production, but in the market, we will still see other kinds of wood paint furniture What problems should consumers pay attention to when purchasing other finishing products? Experts say that apart from beautifying the furniture, the paint surface of furniture is more important to protect the furniture itself, so while emphasizing the environmental protection, the usability cannot be ignored A solvent paint commonly used in oil mixed furniture In terms of service performance and environmental protection, the state has clear mandatory requirements This kind of paint has many colors, so we should pay attention to the problem of heavy metal exceeding the standard Varnish is also a kind of solvent based paint, which is characterized by fast volatilization and good construction It is a commonly used paint in wood furniture at present VOC in the solvent will volatilize rapidly with the drying of the paint, and the qualified products are almost harmless However, in order to improve the processing speed, some manufacturers carry out the next process before the paint is completely dry, which may lead to the VOC in the paint is not exhausted when the furniture enters the house Hand paint hand paint is also called big paint, generally plant oil, mostly used for mahogany furniture, it is true that the more you use it, the brighter it is This technique is relatively rare in common wood furniture However, some people are allergic to lacquer The opening paint and sealing paint are the wood pits left after painting; the opposite of the sealing paint is to seal all the pits This is the common appearance effect of wood furniture These two kinds of paints are the same as other paints in environmental protection and usability Wood wax oil and shell oil are popular furniture finishing products in recent years, mainly playing natural and environmental protection cards However, the reporter asked several testing institutions, and they all said that they had not tested such products and could not evaluate them Industry insiders said that the surface wear-resistant, stain resistant and fullness of such products need to be verified, and they may also decrease with cleaning One of the major functions of the paint film is to resist pollution and wear, and reduce the impact of the environment on furniture If consumers choose wood wax oil and other finishing, it is likely to sacrifice many paint functions Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
