[ China Wardrobe ] At present, most of the panel furniture produced by wood-based panels in the market, including the overall wardrobe ; it is popular in furniture products with its novel style, clear texture, not easy to be deformed, not easy to crack, and anti-mite. a family. However, if the panel furniture made of wood-based panels is used with inferior adhesives or excessive use of adhesives, it is highly likely that the formaldehyde emission of the finished panel furniture will exceed the standard.
Panel furniture based on wood-based panels tends to emit formaldehyde to a different extent during use, which is related to its main constituent material. For wood-based panels, the formaldehyde emitted mainly comes from the following aspects: the free formaldehyde remaining in the reaction when the resin is synthesized; the formaldehyde that has been involved in the reaction during the synthesis of the resin is released during the hot pressing and forming process. Formed formaldehyde; formaldehyde inherent in wood raw materials.
Furniture has added other sources of formaldehyde in its production process, mainly including: a part of formaldehyde remaining in furniture veneer materials (such as melamine impregnated paper) or later; the adhesive used in furniture for various veneers The formaldehyde contained in the adhesive; the adhesive is the main culprit in the release of furniture formaldehyde, accounting for 90% of the formaldehyde released from the artificial board.
Factors affecting the release of formaldehyde in furniture
Furniture is a combination of different materials. Its formaldehyde emission-influencing factors are more complicated than formaldehyde emission from simple plates. However, its formaldehyde release is mainly based on formaldehyde release from wood-based panels. For this reason, we discuss the effects of formaldehyde release on wood-based panels. factor.
Diffusion characteristics of formaldehyde in panel furniture
The amount of formaldehyde released in the panel furniture is related to the tree species of the material of the board, the porosity of the diffusion interface, the density of the board, the structure of the furniture and the way of closing. In the case of wood-based panels, a large number of tests have shown that the main channel for formaldehyde release is the end face rather than the surface, and its formaldehyde release is mainly concentrated on the edge end faces. This is because the rubber layer of the wood-based panel is exposed at the edge of the edge, and the release of formaldehyde passes through the gap between the conduit and the pit, which closes the surface of the sheet and increases the internal power of releasing formaldehyde around the panel. Therefore, in the furniture In the standard, wood-based panels are required to be edge-sealed. In addition to being aesthetically pleasing and preventing deformation, the main purpose is to effectively reduce the amount of formaldehyde released.
In addition, when manufacturing furniture, when the strength requirements are met, the thin plate should be used as much as possible. The effect of furniture decoration on formaldehyde emission is also obvious. In the specific implementation process, low-formaldehyde adhesives, decorative materials and coatings, and reasonable processes should be used to ensure that no new formaldehyde is released after decoration.
Measures to control the amount of formaldehyde released from furniture
The National Mandatory Standard GB18584-2001 "Limits of Hazardous Substances in Wood Furniture for Interior Decoration Materials" was implemented in January 2002. From the requirements of the limit of harmful substances in wooden furniture, the current focus is mainly on the amount of formaldehyde released from wood furniture. Therefore, as a furniture manufacturer that produces wood furniture enterprises or decoration companies, especially artificial boards, it is necessary to pay attention to controlling the formaldehyde content in furniture products. Controlling the amount of formaldehyde released from furniture can be started from the following aspects:
(1) Use the artificial board that meets the standard, and use the wood-based board that meets the standard as the base material for producing furniture. This is the basis for controlling the formaldehyde emission in the wood furniture.
(2) Strengthen the production process of furniture. The artificial board using the E2 mark in the wooden furniture, the standard stipulation must be used for the interior after the finish treatment, that is, the furniture needs to be surface-decorated when the parts are produced. These treatments include surface finish and closure of the end faces of the parts. Therefore, pay attention to the requirements of the process and minimize the release of free formaldehyde.
(3) Reasonable use of formaldehyde-free or low-formaldehyde adhesives. In addition to this, a formaldehyde scavenger is also used to capture formaldehyde. With the continuous improvement of consumers' awareness of rights protection, the purchase of furniture is particularly important for the release of formaldehyde. At present, the national mandatory standard GB18584-2001 wooden furniture in the limit of harmful substances: formaldehyde emission limit value ≤ 1.5mg / L. If the test report shows that the formaldehyde emission of the product does not exceed the national standard, consumers can rest assured to buy.
Dog Crates is a kind of Pet Cage. The surface treatment of cages are plastic spraying, plastic dipping, electrophoresis, chromium plating, galvanizing, imitation gold, etc.
There are mainly the following types,
1. Detachable Pet Dog Fence type:
It's simply to surround and limit the range of activities of the little guy. The mother dog and the baby dog can be isolated together to avoid injury. Or put it in the yard for little dogs to play, limiting the scope.
2. Folding Pet Cage type:
The light and foldable cage is suitable for people who don't have much space at home. This is suitable for some small dogs or puppies.
3. Heavy Duty Dog Cage type
Weight type, always at home. It is suitable for medium and large dogs and is durable.
The role of dog cages.
1. Convenient for cleaning
Prepare a cage at home to let dogs get used to living in the Dog Kennels Cages, which can greatly reduce the behavior of dogs excreting at home, and it can also be more convenient for owners to clean.
2. Provide a safe space
Dogs are cave animals. Compared with open space, narrow cages are more suitable for dogs, because they can make dogs feel safer.
3. Isolate dogs from people
For example, when guests come to the house, because dogs are still a little wary of strangers, in order to appease guests and dogs, dogs can be temporarily caged.
4. Avoid dogs tearing down their homes and correct their behavior
When the owner is not at home, the owner had better keep the dog in a cage, which can avoid the dog's behavior of tearing down the house, and can also correct the dog's random biting behavior. If the dog is biting during the tooth change period, the owner can give the dog a bit of molar snacks or Pet Chew Toys to bite and reduce the pain and itch.
5. Reduce random eating
Another advantage of keeping dogs in cages when they are alone at home is to prevent dogs from eating indiscriminately.
Therefore, it is better to prepare a dog cage at home and use it at an appropriate time. When you are usually with dogs, it is recommended to do more training for dogs to improve their obedience. If you perform well, you can give some dried chicken as a reward, so that you can clean your teeth while training.
