Method.
Background technology
In recent years, the harm of formaldehyde is increasingly taken seriously, and formaldehyde is a kind of colourless readily soluble irritative gas, to human body
Have compared with major injury.It is used for interior containing the woodwork that formaldehyde adhesive makes, the Form aldehyde release phase is 15 years.Research shows：
Long Term Contact low dosage formaldehyde can cause chronic respiratory disease, cause nasopharyngeal carcinoma, colon cancer, brain tumor, paramenia, nucleus
Gene mutation, DNA single-stranded interior commissure and DNA and protein commissure and suppress the reparation of DNA damage, pregnancy syndrome, cause
Neonatal chromosome disorder, leukaemia, cause teenager's memory and intelligence to decline.In all contactees, children and pregnant woman
PARA FORMALDEHYDE PRILLS(91,95) is particularly sensitive, endangers also just bigger.Formaldehyde is more highly toxic material, in China's toxic chemical priority acccess control list
Upper formaldehyde is in second.Formaldehyde is defined as carcinogenic and causes deformed material by the World Health Organization, is that generally acknowledged metamorphosis is anti-
Ying Yuan, is also one of potential strong mutagen.
The adhesive of formaldehyde is just free from without aldehyde glue, is used primarily in wood-based plate and building material industry, particularly fitment material for family,
Conventional panels glue coordinates flour, high temperature hot pressing production technology based on Lauxite, phenolic resin.Urea and formaldehyde pass through contracting
Poly- reaction mating surface amyloid proteins, cost is low, there is good water proofing property and dry tenacity.And have big in Lauxite, phenolic resin
The residues of formaldehyde of amount, influences indoor environment for a long time, up to the slow release of decades.
With the development of society, suppress environmental pollution has derived a series of newborn materials with the pursuit to environmental protection
Material, such as bio-based materials, bio-based materials are entirely to be done by biotechnology.It is compared with present petroleum based material
There are several benefits：One is to reduce the dependence to oil；Second is the discharge for reducing carbon dioxide, because its main source
In plant；3rd is that it can be biodegradable, meets the advantage of present environmental protection；Its other whole production process is gentleer, is not
High temperature, high pressure, the Chemical Manufacture of organic solvent, its comparision of production green.For entirety, meet very much said " low-carbon
The requirement of economy ".
