On the one hand, the production process of the particleboard is relatively simple and the cost is low, which makes the price of particle boards relatively low in the market and can meet the purchase needs of most consumers.
On the other hand, the density of the particleboard is high, the hardness is large, and it is not easy to deform, which can ensure the stability and durability of the furniture.In addition, the particleboard also has the characteristics of good sound insulation and fire resistance.
Everything has two sides, and the particleboard is no exception.Although it has many advantages, there are some shortcomings.First of all, due to the need to add adhesives during the production process of the particleboard, harmful substances such as formaldehyde may be released during use, causing potential threats to human health.Secondly, although the internal structure of the particleboard is tight, due to the smooth surface, it is easy to scratch the surface of the furniture or leave scratches.In addition, the resistance of the particleboard is poor. If it is in a humid environment for a long time, it is easy to cause expansion or mold.
From the perspective of production technology, currently aldehyde -free adding particleboards mainly use isocyanate gel (MDI glue) as adhesives.The synthetic raw material of MDI glue is oil. The isocyanate group (—NCO) in its molecule can react with the water reaction to generate a bond and release carbon dioxide. Therefore, it can achieve fast curing at room temperature without adding curing agents and catalysts.The initial viscosity of MDI glue is better, which can be suppressed at a lower temperature and shorten the heat pressure time.
Moreover, because MDI glue does not contain formaldehyde, and volatile low -toxic monomer content is extremely low, it is considered an environmentally friendly adhesive.However, the price of MDI glue is higher, which leads to an increase in production costs, which is also the main factor restricting its large -scale application.In addition to using MDI glue, other types of aldehyde -free adhesives can also be used, such as phenolic resin glue, protein glue, inorganic glue, etc.These adhesives have their own advantages and disadvantages, and companies need to choose suitable solutions according to their own conditions.
In the production process, the formal protection technology and equipment are also adopted during the production process, such as low temperature and low pressure continuous flat pressure technology, drying gel technology, etc., which further improves the environmental performance of the product.At the same time, the surface of the aldehyde -free particleboard is smooth and smooth, the texture is clear and beautiful, which meets the aesthetic needs of modern home design.
The trend of aldehyde -free particle boards. With the pursuit of healthy home life, the plate -free plate has gradually become a consumption trend.The so -called "aldehyde -free" does not have formaldehyde at all, but the amount of formaldehyde has reached a certain standard.According to the national standard GB/T 39600-2021 "Hololes Classification of Formaldehyde Release of Artificial Plates and its products", the release of formaldehyde release is E1 ≤0.05mg/m3, which can be marked as ENF-level aldehyde-free add plate.
