Recently, the domestic furniture market can be seen everywhere in the business to play the "zero formaldehyde" slogan, in the face of these self-proclaimed formaldehyde-free, but the price is 20% higher than ordinary furniture, consumers are confused, I do not know if it is true Formaldehyde, or pit people? The long-term release of formaldehyde in all wood-based panel furniture is extremely harmful to the human body due to formaldehyde, and it is an unavoidable problem in the home decoration process. It has always been the focus of attention in home consumption. It is generally accepted that long-term inhalation of formaldehyde can cause direct skin and respiratory diseases such as allergies and asthma, and may cause cancer, leading to serious diseases including leukemia, uremia, colon cancer, and brain cancer. For children, the elderly, pregnant women, formaldehyde is particularly harmful. Wood-based panel furniture is the most important and long-term source of indoor formaldehyde. Almost all wood-based panels release formaldehyde for a long time. This release will be accompanied by the life of wood-based panel furniture. China divides wood-based panels into E2 and E1 grades according to the amount of formaldehyde released. However, it is worth noting that compared with the European and American standards, the current "contract" standard on the market is still very loose. Therefore, the Chinese wood-based panel industry has also adopted the “E0 grade†standard to distinguish artificial panels with relatively small amounts of formaldehyde. After visiting the professionals, the reporter concluded that whether it is E2, E1 or E0 standard wood-based panels, because of the continued formaldehyde release, when the room has a limited volume, large decoration density, limited ventilation conditions (especially during sleep) In the case of the bedroom, there are different degrees of risk of excessive formaldehyde. Some respondents claimed that about 80% of new homes in China are facing excessive formaldehyde. A furniture manufacturer who asked not to be named also said that if there is a "zero formaldehyde" household product in this case, it is a revolutionary solution to the health threat of formaldehyde to the living environment. Its health value to the public and its marketing value to the business will be enormous. Market research does not use ecological adhesives for wood-based panels are not "zero formaldehyde" According to a sheet manufacturer, the basic reason for the continued release of formaldehyde in ordinary wood-based panels is that the manufacturing process of artificial panels requires the use of aldehyde adhesives, such as urea-formaldehyde resins. “This kind of adhesive is a direct compound of formaldehyde and urea. Because it is cheap and has good bonding effect, it is used in the manufacturing process of wood-based panels. But the biggest disadvantage of this kind of colloid is that it is under natural conditions. It will continuously decompose and reduce spontaneously, and release free formaldehyde. In the hot and humid environment, the reaction speed of this decomposition and deliquescence will double." "The difference between good wood-based panels and poor materials is that they can be replaced by ecological glue. Urea-formaldehyde resin. The safety and stability of eco-adhesive can be free of formaldehyde and will not decompose free formaldehyde. It can also supply the more popular 'zero formaldehyde' furniture on the market." Some people said, "zero formaldehyde "The wood-based panels also need to pass the national aldehyde-free test. In addition, the plate itself is made of natural fibers such as straw. In this natural fiber, it does contain only a small amount of natural aldehydes. "Even if the formaldehyde content of rice is not completely zero. The so-called wood-based panel produced from natural fibers. It is 'the plate that does not release formaldehyde' is more rigorous than the 'zero formaldehyde' statement." With the "zero formaldehyde" method to win the furniture sales, pit father! With the "zero formaldehyde" sheet, is it possible to produce "zero formaldehyde" furniture? Xiaobian further verified the industry's people. It turns out that from sheet metal to furniture, it needs to be processed by veneering, painting and edge sealing. From this fact, unless all zero aldehyde paint, zero aldehyde edge seal, and zero aldehyde veneer are used, even if the sheet is "zero formaldehyde", formaldehyde will be introduced due to these processes. “Because of process and cost constraints, complete aldehyde-free processing is difficult to achieve.†Industry salespeople say that some “preparations†are just a propaganda to win sales. In addition, the long-term formaldehyde release of furniture is mainly derived from wood-based panel substrates. The amount of formaldehyde introduced by veneers, paints, etc. is relatively small. The formaldehyde in the veneers and paints are distributed on the surface of the furniture, and most of them can be volatilized in a short period of time (generally 2-3 weeks), so there is no excessive health hazard to the human body. The “zero formaldehyde†furniture produced with zero formaldehyde sheet should be a concept of “about zero formaldehyde†and a simplified title for convenience. There is one aspect that is not rigorous enough, but there is no intention to deceive consumption. Of course, there are also brand merchants who have adopted a more cautious slogan in order to avoid unnecessary business troubles, such as the use of "zero formaldehyde space".
Stainless Steel Sliding Door
Characteristics and Advantages
(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;
(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.
(3) Anti-clamping function: automatically reverse when meeting barriers;
(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)
(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;
(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;
(7) Bi-doors inter-locking: one of the door leaves always remains closing;
(8)Safety sensor terminal: sensor stops working when door closed;
(9)Unique coating technology: never rusty;
(10)Easy and convenient to install;
(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.
