We all know that glue is the source of formaldehyde, why use formaldehyde glue?
For the simplest example, even if it is boiled water, can you scoop it up with a spoon, put it into a cup, and then pour it in? There will definitely be air bubbles in the process, and the glue will work.
The real design is “people-oriented”, designing better products under the premise of solving design needs, and providing better products with less price. Although the choice of cheap adhesives greatly reduces the cost, it brings not only inefficient production, but also safety issues, such as long-term use, which will cause irreversible factors such as shell deformation and loosening. To sum up, choosing the right adhesive is the one with the smallest formaldehyde emission and the most formaldehyde-free addition of formaldehyde-free glue, formaldehyde-free addition of high-performance metal adhesive, and the default when the voc reaches a certain concentration, the state requires that e2 must be released.
You must have misunderstood how resin works, which requires glue. The principle of glue: Adhesives bond the glue in the environment, because they are not a natural pair and need to be run in! There are different bonding methods! As for why they are not cheap, I am not sure. That is, the materials and processes of each glue are different, the performance is very different, and the cost is different.
The pure crystal resin is a low-carbon resin, the formaldehyde release ratio is low and the normal temperature resin is a two-component, and the bonding stability is poor, and the formaldehyde release ratio is high. There is also the problem of stability. The stability of some amorphous resins is very poor, and the problem of delayed release often occurs, or the release is unstable and the loss is too fast.
In fact, there is no environmentally friendly glue, and formaldehyde-free glue is not environmentally friendly. Because the glue has the possibility of containing formaldehyde in the production process. Environmentally friendly glue is the upstream manufacturer decomposes the glue through advanced science and technology, releases formaldehyde that is harmless to the human body, and can reduce the potential safety hazards that may occur in the traditional bonding method from sheet to bonding parts. Formaldehyde-free adhesives on the market are usually in the form of adhesives, and a series of different resins are used to decompose during bonding to reduce the pollution and volatilization of harmful gases such as benzene series, formaldehyde, tvoc, etc. The problem of incompatibility and conflict of various adhesives improves the bonding quality. The use of aldehyde-free adhesives, combined with imported adhesives, can reduce the pollution of the entire environment to the human body, and it also has non-toxic, harmless, and pollution-free green products.
Even if you buy formaldehyde-free glue with imported raw materials, you will still generate formaldehyde during use! It does not rule out that the glue you use is not qualified at all. After all, no matter how environmentally friendly the glue is, there will be some environmental problems. Additives generally have volume control, and cannot be added casually like ordinary adhesives. The cost increase is understandable. Formaldehyde release, which seems to be small, may rise to endanger human health and bring harm to newly renovated houses. Not to mention this kind of glue that has a large enough area of environmental pollution to threaten life from various aspects such as materials, environment, soil, etc.
