What is the MDF? What are the environmental standards for MDF?
What are the environmental standards for MDF? This question is for everyone today. At present, according to the current national and international standards, MDF should be directly applied indoors, must reach at least E1 and 1.5mg/L. If this standard is not met, it must undergo certain deep processing (edge ​​banding, paste Face, etc., so that the finished product eventually reaches the E1 level, so this standard is a mandatory standard and a minimum standard. 1.Hinges Kitchen Hardware,Kitchen Metal Hardware,Water Faucet,Kitchen Hardware Accessory, Kitchen Wasserbecken OYEAL Global , https://www.oyealhome.com
First of all, we must confirm what is called the environmental protection board. Plates that are completely free of formaldehyde are absolutely non-existent. It is important to make clear that even pure solid wood plates release an aldehyde known as furfural.
Along with the improvement of production technology, more international standards than E1 are introduced by the MDF industry (although the highest national standard is still only E1), these international standards mainly include E0, CarbP2, F four stars. Grade, the more common one is E0 grade (formaldehyde emission 0.5mg / L, lower than the formaldehyde content of water, formaldehyde formaldehyde release of 0.9mg / L) and CARBP2 grade. The E0 level and the CARB P2 level use different measurement methods, so the values ​​are different, but the level of both can be considered the same. This kind of certificate country cannot be issued, because these are international standards. China currently only has the E1 standard. Other standards are not available. However, there are still authoritative international testing organizations, such as SGS, TUV, etc., which can issue CARBP2 certificates.
Therefore, depending on the environmental protection grade of MDF, it is to look at the formaldehyde emission level of MDF: E0 is better than E1, CarbP2 is basically the same as E0, and F4 is better than E0.
When purchasing medium-density boards or furniture made of MDF, you can choose the board or sheet product that corresponds to the environmental protection level (formaldehyde release level) according to your actual situation. The dealer can provide the corresponding certificate. If it is E1, it needs to provide the national inspection report. If it is CABRP2, it needs to provide the certification of international institutions, SGS, TUV, etc. At the same time, in general, the side of the board will have the manufacturer's code, and the formaldehyde release level will also be indicated.
The role of the hinge is to connect the cabinet and the door panel, in eating at the same time it is still alone to bear the weight of the door panel, keep the door arrangement with consistency. For hinges, cheap or try not to buy, it is not like a washbasin can say change, good hinges not only long life, installation is also more convenient.
2.Slide rail
If the hinge is the heart of the cabinet, slide rail is equivalent to the kidneys. Large and small drawers can be free to push and pull, depends on the slide rail. Slide rail has roller, steel ball, gear three kinds of classification.
3, damping
Damping is mainly with the slide and hinges, has two important roles, one is to prevent shock absorption, the second is to enhance the accuracy of hardware. Damping hinge is a kind of hinge, can also be called hydraulic hinge. It can close the cabinet in a certain zone by itself, even if the force to close the door, can also slow down the speed to close the cabinet.
4.Hanging code
Hanging code is a small hardware accessory that can be hung on the wall, it can realize the link between the hanging cabinet and the wall. General steel invisible hanging code is stronger, aging cycle is relatively long.
5.Pull-out basket
Pull the basket do not have to choose too much or too high-tech, generally one or two on it, all depending on their own use of happy can be.
6, faucet
Faucet is an essential hardware item in each of our homes. Faucet good or bad, there are more critical five points, material, spool, bubbler, plating, water inlet hose.
Copper is currently a better material in the manufacture of faucets, also called brass.
Spool cost in 4 ~ 20 yuan are available, the more commonly used spool cost generally between 5 ~ 15;.
Bubbler is mainly installed in the spigot's water outlet end, the device that mixes and air when the water comes out. This class increases the flushing force of the water to achieve water conservation.
electroplating can enhance the corrosion resistance and wear resistance of the faucet and improve the aesthetics.
Intake hose is mainly connected at the corner valve and faucet, belonging to the class of accessories, while the hose and not resistant to high pressure and high temperature, long-term water pressure when the hose connector will come out, all in looking at the hose, the hose pipe and joint need to pay special attention to a little.
7.Water basin
Basin material can be divided into stainless steel, artificial stone, ceramic three categories. Currently used in our kitchen, mainly stainless steel. Stainless steel material has light, environmentally friendly, durable, corrosion-resistant features, the style is also more.
8.Drawers
When choosing a drawer, the general standard size control in 30cm-100cm best, 30cm-70cm is a small drawer
