Melamine is a chemical that has many industrial uses. In the United States. it approved for use in the manufacturing of some cooking utensils. plates, plastic products, paper, paperboard. and industrial coatings, among other things. Besides, although it is not registered as a fertilizer in the U.S., melamine. has used as a fertilizer in some parts of the world.
Melamine may used in the manufacturing of packaging for food products. but is not FDA-approved for direct addition to human food or animal feeds marketed in the U.S.
The Taiwan Consumers' Foundation recently tested plastic tableware made in China and found. that it contained melamine at a level of 20,000 parts per billion. This type of tableware manufactured with a substance called melamine-formaldehyde resin. It forms molecular structures that molded, with heat, to form the shape of the tableware.
A small amount of the melamine used to make the tableware is "left over" from this chemical reaction. and remains in the plastic. This left-over melamine can migrate very out of the plastic into food. that comes into contact with the tableware.
melamine faced mdf selection
What melamine faced mdf selection melamine quality method From the mdf board appearance. it can seen that the size and shape of sawdust particles at the center of the cross section are large, . and the length of wood is generally 5-10mm. If the length of mdf sheet is too long. the structure is loose, and the anti-deformation force is too short. the so-called static bending strength is not up to standard.
The moistureproof of wood-based panels depends on its density and moistureproof agent. in the water soaked moistureproof is not good. moistureproof refers to moistureproof gas, not waterproof. so in the use of the future to distinguish.
China want to control in 8-10% is appropriate. Southern areas including coastal areas should controlled in 9-14%, otherwise the plate is easy to absorb moisture deformation.
From the surface flatness and smoothness. generally when leaving the factory to go through 200# about sandpaper light,the general situation is fine, but in some cases, such as sticky fire board, too fine to hang glue.
