{Environmental protection}
When many people choose boards, the first thing they pay attention to is the environmental friendliness of the boards. Generally, when we look at whether a board is environmentally friendly, we mainly focus on the formaldehyde content of the boards.
I believe that when you are shopping for boards, you will hear the shopping guide say, E1 grade, E0 grade... But most people don’t know what this means. In fact, if you want to find out the formaldehyde content of the board, you only need to remember two points:
Part.01
Sources of formaldehyde
A small portion comes from the wood itself, while the majority comes from the glue used to hold the boards together. Manufactured wood panels are the most well-known source of formaldehyde release, primarily plywood, blockboard, medium-density fiberboard, and particleboard. Without formaldehyde, there is no glue. These panels require adhesives, which are formaldehyde-containing resins, primarily urea-formaldehyde resins, based on formaldehyde. Urea-formaldehyde resins are widely used due to their low price and excellent bonding properties.
Part.02
The highest standard for judging the environmental protection of panels
The national standard GB/T 39600-2021 "Classification of Formaldehyde Emissions from Artificial Boards and Their Products", previously proposed by the State Forestry and Grassland Administration and co-drafted by Nanning Ketian Water-based Technology Co., Ltd., was officially released on March 9, 2021 and will come into effect on October 1, 2021.
This standard further refines the formaldehyde emission classification of artificial boards, specifically E1, E0, and ENF. E0-grade artificial boards now have a unified official (national standard) identity, and the debut of ENF-grade boards also provides a basis for the designation of "NF" (No Formaldehyde).
{Focus on stability}
In addition to paying attention to environmental protection, stability is also crucial, which directly determines the service life and even safety of the board. To determine whether the selected board is stable, you can look at two points:
Part.01
Nail holding force
In custom-made furniture, a large number of hardware are used, such as screws, hinges, etc. Whether these hardware can be firmly combined with the board reflects the nail holding strength of the board.
To put it simply, it means whether the nails are easy to fix in the holes after entering the board, or whether they are easy to loosen and fall off.
Boards with good nail holding power have stronger fixing force for nails, and nails are not easy to fall off after long-term use. They can also withstand more weight, and the nail holes can be used repeatedly.
If the nail holding capacity of the board is poor, the nails will loosen easily over time, causing the furniture to deform, shake, make strange noises, or even fall apart. This not only affects the lifespan of the furniture but also threatens the safety of the family. For ordinary consumers, the easiest and most intuitive way to determine the nail holding capacity of the board is to directly check the quality inspection report.
Part.02
Static bending strength
Static bending strength refers to the pressure strength that the plate can withstand when it is bent to the point of breaking under force. Simply put, it is "how much force can break the plate."
If the static bending strength index is low, the board will be prone to deformation and cracking when subjected to stress. The probability of damage and breakage during use will be high, resulting in a short service life and a high safety hazard. The static bending strength is related to the raw materials, age of the tree, and processing technology. If you want the board to be durable, you can ask about the age of the tree when selecting the board. Generally, wood between 15 and 30 years old is better.
However, in addition to the board itself, the style design of custom furniture also affects the static bending strength. If the span of the cabinet shelves is made particularly large, then no matter what kind of board it is, it may bend.
{Pay attention to moisture resistance}
Moisture resistance refers to the "water absorption expansion rate" of the board. The degree of expansion of the board when exposed to water determines to a certain extent whether the board is easy to deform.
The testing standard for the water absorption and expansion rate of artificial boards is 2h, which means cutting a section of the board, soaking it in water for two hours, and seeing if it deforms.
For wood panels, moisture resistance simply means preventing them from swelling and deforming in areas with relatively high moisture content, such as kitchens and bathrooms, which could affect the countertop's load balance and hinge grip. This is not only related to the board's rate of expansion after water absorption, but also to the edge-sealing process after the panels are cut.
To sum up, stability and moisture resistance determine the physical properties of the board, while environmental protection determines whether it is safe for us to use. If urea-formaldehyde glue is used in the production process of the board, it is likely to cause formaldehyde to exceed the standard, thus threatening our health.
Relying on the mature application of water-based polymer technology and formaldehyde-free glue and formaldehyde-free board technology, Shuixing Ketian has successfully created core products such as formaldehyde-free ecological boards, formaldehyde-free particle boards, high-polymer KT boards and non-toxic customized boards, realizing formaldehyde-free, non-toxic and industrialized production and application of the entire series of artificial boards, and has become a domestic high-quality supplier of formaldehyde-free boards, formaldehyde-free flooring, and non-toxic home improvement materials/furniture materials. It can provide comprehensive, efficient and non-toxic support for whole-house customization, and provide consumers with a non-toxic and odorless home environment that is ready to move in.
