Does HPL fire-proof panel contain formaldehyde? Can it be safely used?
It is one of the common problems in the building materials market whether the HPL fire-proof and paint free panel contains formaldehyde. Today we will uncover the truth of formaldehyde in fire-proof board. What materials are made of? Can you use them safely?
Analysis of the truth of formaldehyde in HPL fire-proof panel
1. What is HPL panel?
HPL veneer refers to putting the paper with color and texture into phenolic resin adhesive for soaking, drying and curing the steel plate with texture to a certain extent after high temperature and high pressure, and then laying it on the base material with glass magnesium board, particleboard, MDF, big core board and solid wood board as the main body, with white emulsion as the adhesive, the plate can be bonded and bent only under normal temperature Plate needs a certain temperature to be constructed!
2. HPL veneer contains formaldehyde?
When it comes to formaldehyde, it makes people change color. No matter what kind of finished boards are used for decoration, they will contain this kind of substance more or less. Free formaldehyde Formaldehyde, generally speaking, in the production process of plates, furniture, coatings and adhesives, a large amount of formaldehyde is required as the carrier. However, in the high-temperature production line, most of formaldehyde has generated glue, which is no longer formaldehyde. Such formaldehyde has no harm to human body. In the process of production, a small part of formaldehyde did not participate in the reaction, so it became free formaldehyde. Free formaldehyde is everywhere in our lives.
Since the HPL panel contains formaldehyde, isn’t it useless? Of course not. In fact, in our life, the existence of formaldehyde is inevitable. Whether it is used for living or even eating, it may release free formaldehyde. Therefore, in real life, as long as the formaldehyde concentration is controlled within a certain range, it can safely use a certain material, HPL veneer is no exception.
3. What is the formaldehyde emission level of HPL panel?
There are three levels of formaldehyde emission limit of HPL panel: E0, E1 and E2. The first two can be directly used in the interior, and the latter can only be used in the interior decoration after being treated.
Generally speaking, E0 refers to the numerical mark of formaldehyde content less than 0.5mg/l (E0 ≤ 0.5mg / L). In the national standard GB / t9846.1-9846.8-2004 of interior decorative board issued last year, the formaldehyde limit level is divided into three levels, namely E2 ≤ 5.0mg/l, E1 ≤ 1.5mg/l, E0 ≤ 0.5mg/l.
HPL panel products, formaldehyde environmental protection level has reached the national regulation of E0, has reached the standard, consumers can use at ease.如无特殊说明，文章均为本站原创，转载请注明出处。If there are no special instructions, the articles are original, if you want to use or reproduce, please indicate the original source www.plywoodinspection.com,If you find that our articles infringe on your copyrights and interests, please email us at email@example.com in time and we will delete it at the first time.
