What is the difference between the wardrobe plates e1, e2, e0? How to identify with the easiest way

Everyone knows that it is easy to produce formaldehyde when decorating. This kind of formaldehyde can't be avoided. It can only be said that the use of some environmentally-friendly materials to minimize the release of formaldehyde is inseparable from environmental protection grades e1, e2. The selection of the wardrobe board with e0, the difference between the wardrobe sheet e1, e2 and e0 and the identification method are explained here.

The difference between the wardrobe board e1, e2 and e0

At present, the formaldehyde limit level is divided into three levels: E2, E1 and E0, namely:

E2≤5.0mg/LE1≤1.5mg/LE0≤0.5mg/L More images can be described as such, E1 level: 100 square meters of house smoke, can smell smoke; E0 level: 10 square meters smoke in the house, Smell the smell of smoke,

According to the national compulsory standard, after 1 hour of closing the doors and windows, the formaldehyde emission per cubic meter of indoor air should not exceed 0.08mg; if it reaches 0.1-2.0mg, 50% of normal people can smell odor; reach 2.0-5.0mg will Irritating to eyes and trachea, and sneezing and coughing; reaching 10mg or more can cause difficulty breathing; if it reaches 50mg or more, it can cause serious diseases such as pneumonia and even death.

Method for identifying wardrobe boards e1, e2 and e0

(1) smell the board

Edge strips and finishes do not completely enclose volatile materials, which makes many new furniture still have a strong chemical taste. New furniture made of zero-formaldehyde straw boards, especially cabinet furniture, opens the door with a hint of grassy fragrance. It is easy to identify formaldehyde from the smell,

(2) Partial identification board

Using straw straw fiber, the cross section of the zero-formaldehyde sheet has a dense layered structure, which is different from the fine-grained structure of MDF (MDF) or the granular structure of particleboard (particleboard), even if the finished product has been edged and finished. It is easier to observe and identify through the section and hole of the groove before assembling the furniture.

(3) boiled test board

If possible, ask the merchant about some corners of the furniture and boil it in hot water to distinguish between true and false. Compared to MDF boiling water, the advantage of water swelling ratio is very obvious under the same experimental conditions. After the boiled plate boils, it is found that the aroma plate keeps boiling at high temperature and still maintains high strength, and the MDF breaks at a glance, because the straw-rich wax layer itself has a moisture-proof effect, and the MDI glue in the straw plate does not Decomposed and dissolved in water, which makes the straw board have a very high moisture resistance coefficient and adhesive strength, and it has the advantage that the ordinary board cannot be matched.
