Strengthening the floor to pay for the concept of zero aldehyde, furniture products are known as paint-free zero aldehyde, home improvement company hit the "zero aldehyde home improvement" banner ... now, whether it is into the home shopping mall or at the high-speed rail station, airport, zero aldehyde concept advertising and sales The caliber is coming. However, in the mixed shopping malls, do you really have so many "zero aldehyde" products? In this regard, the industry said that the concept of "zero formaldehyde" is popular, mainly because the business wants to see the eye. In fact, furniture production is a systematic project, and many factors in this process will affect the environmental quality of furniture.
The concept of "zero aldehyde" is flying all over the sky
“Our floor is absolutely zero formaldehyde content, the glue used is pure natural plant glue, in line with EU national standardsâ€, “Our product formaldehyde emission is absolutely less than 0.1 mgâ€, “our furniture is matte paint free , absolutely zero formaldehyde." Into the furniture and building materials store, such as the purchase of a large number of shopping guides, consumers are often induced by the firm's firm tone to generate purchase behavior.
A few days ago, the reporter came to a wooden floor store, the owner strongly recommended a paint-free solid wood floor, the product is absolutely free of formaldehyde. The reporter took the sample and observed that the product is not much different from other products, but it feels more rough. In this regard, the owner categorically said that the surface of this product is wood wax oil, wood wax oil is mainly composed of refined vegetable oil such as refined linseed oil, palm wax and plant wax combined with other natural ingredients, so it does not contain formaldehyde.
The reporter went into a custom-made wardrobe store, and the poster at the door promoted a man-made paint-free board that claimed to be awarded the “Scientific Progress Awardâ€. According to the store's shopping guide, this product uses MDI ecological adhesive, which is also used for artificial blood vessel and heart valve surgery. He pointed to the various certificates hanging on the wall and said: "The certificate is very complete and consumers can use it with confidence."
The reporter also found that a number of well-known finished furniture stores, including colorful life, began to introduce water-based wood lacquer for furniture surface coating to reduce the amount of formaldehyde emission, and some second- and third-line brand furniture products claimed to use paint-free. Process, can achieve the effect of zero formaldehyde release.
Businesses are stealing concepts
In response to the increasing number of "zero formaldehyde" products on the market, the reporter learned that no matter whether it is wood or wooden doors, whether it is finished furniture or custom furniture, whether it is solid wood or plate type, there are indeed some enterprises that produce home products that have reached E0. Level standard. However, some insiders also said that the concept of “paint-free†is the eye-catching practice of the business. It can only be said that no formaldehyde was artificially added during the production of the board. Although wood wax oil and MDI ecological glue are indeed environmentally friendly adhesives, it does not mean that the finished product has no formaldehyde. Because the naturally growing wood itself contains traces of formaldehyde. For example, in the case of lacquered solid wood flooring, some of these products use wood with low formaldehyde emission as the substrate, and when the wooden floor is paved, glue is inevitably used, so zero formaldehyde is only a legend.
In fact, the formaldehyde released by wooden furniture or building materials is mainly derived from the adhesive used in the processing of raw material sheets. The so-called "aldehyde-free" is only used in the production of sheet metal without the addition of formaldehyde, such as the use of modified corn starch glue instead of the traditional urine aldehyde rubber, but this does not mean that formaldehyde is not present in the final product. Since the wood itself contains trace amounts of formaldehyde, the “zero formaldehyde†promoted by the merchant is a concept of stealing, which is actually “zero addition of formaldehydeâ€.
Multiple factors affect environmental quality
Zhang Chengzhi, vice president and secretary general of the Guangdong Furniture Association, said that furniture production is a systematic project. In this process, many factors will affect the environmental quality of furniture. Plates are only one kind of substrate used in furniture processing. However, in the process of processing, a large amount of raw materials such as edge-sealing adhesives and door lacquers are used. As a solvent, formaldehyde is widely used in these raw materials. Even imported high-grade edge-sealing adhesives and paints have formaldehyde release, not to mention some low-quality raw materials. At the same time, in addition to the plates, custom furniture also has countertops, kick lines and hardware accessories. Whether these materials are environmentally friendly will also affect the environmental quality of custom furniture; in addition, the processing technology is also a factor in determining whether it is environmentally friendly. Therefore, it is not the use of furniture that uses E1 and E0 environmentally-friendly standard plates to achieve high environmental standards.
The reporter learned that at present, the formaldehyde limit level is divided into three levels of E2, E1 and E0, namely E2≤5.0mg/L, E1≤1.5mg/L and E0≤0.5mg/L. The data shows that the formaldehyde content of drinking water is 0.9 mg / L, that is, the formaldehyde content of the E0 standard is less than that of drinking water. The Japanese "F4 Star" standard (≤0.3mg/L) is the most stringent environmental standard recognized by the international community. The E1 environmental standard is a national mandatory health standard, and it is a mandatory “safety standard lineâ€.
Identifying formaldehyde can't be heard
Compared with finished furniture, nowadays custom furniture is loved by more and more newly married young couples. According to Zeng Yong, Secretary General of the Guangdong Wardrobe Industry Association, starting from 2014, more and more custom brands have adopted E0 under the leadership of first-line brands such as Sofia, Federal Gordon, Dinggu, Shangpin Home, and Weiyi. Grade plate, Marg and other brands use the “Super E0†plate provided by Daya Wood-based Panel Group, and the environmental protection standard meets the Japanese F4 star standard.
When purchasing custom furniture, the media often pointed out in the purchase strategy for consumers that "If you smell it with your nose, you can judge whether the product is environmentally friendly or not." However, is this really feasible? Liu Chengyu, general manager of Tianxiang Board Industry, said that formaldehyde itself has certain irritating properties, but the irritating effect is mainly on the eyes (feeling eye discomfort, tearing, etc.), which is actually colorless and odorless, without speciality or Distincable odor. When consumers buy sheet furniture, the smell they smell is more of the smell of the board substrate itself or the smell of glue and paint, not the smell of formaldehyde. In other words, odor does not mean formaldehyde. Excessive formaldehyde, the nose is actually not smelling.
Zhan Manjun, the well-known plate supplier Fenglin Yachuang, also explained to reporters that the raw materials of the plates often contain multiple tree species. Different tree species themselves have some odors, and the smell of individual tree species is not so good. The smell of different tree species is often mixed with a single smell that is more unpleasant. Due to the lack of public understanding of this, many custom brands have repeatedly placed their guns in front of the smell.
How to ensure the environmental protection of custom furniture?
So how do consumers ensure the environmental friendliness of custom furniture? In this regard, Zeng Yong said that when signing a purchase contract with a custom brand, remember to indicate in the contract what grade of board is used to better protect its consumer rights.
According to Zhan Manjun, with the continuous upgrading of downstream custom brand environmental protection requirements, upstream manufacturers are also beginning to increase the proportion of E0 grade sheet production lines. Some of the more well-known custom home brands use adhesives and glues are very particular. For example, Shangpin Zhuangjiao, Ou Pai, etc. use German Glue King; Marg uses the German Jiaowang JOWATHERM hot melt adhesive; and Sophia, Cobo Boloni and other custom home furnishing enterprises also use high quality glue.
For the meat marinating solution we refer to meat tenderizer, Saline mixer, Saline injector(brine injection systems), vacuum massage tumbler.
Saline injector can evenly inject the brine and salt auxiliary materials into the meat blocks, which can shorten the pickling time and greatly enhance the taste and yield of the meat products. The machine can be adjusted with stepping rate, stepping distance, injecting interval and injection pressure according to the technological requirements. Then the brine and salt auxiliary materials can be injected into the meat evenly and continually to reach the optimal effects.
While vacuum tumbler makes meat rolled in the drum under vacuum condition, similar to pulmonary respiration (make product to inflation and shrink alternatively). It makes meat salted evenly, increases the adhesive quality and taste and ensures the freshness of meat.
