Over 30 years, the timber industry of China is developed rapidly.2006, the ten thousand stere of wood-based plate total output 7428,
The wherein ten thousand stere of glued board 2729, the ten thousand stere of core-board 1155.Wood-based plate total output, glued board yield, furniture yield
Occupy No. 1 in the world.
It is particularly gluing using Lauxite in a large number due to generally using formaldehyde system adhesive in Wood-based Panel Production
Agent, causes wood-based plate and its product (furniture, timber floor, Indoor Wooden ornament materials etc.) to there is Form aldehyde release, is room
The main source of formaldehyde pollution in interior air pollution.
With the increasingly raising that people's health consciousness, indoor environment consciousness, quality of life are realized, artificial board formaldehyde release is made
Into contaminated air, infringement health problem be increasingly subject to people's attention.In the city of China, after " coal smoke type ", " photochemistry
Smoke-type " pollution after, modern just falling into " room air pollution " be mark the 3rd pollution period.One Beijing City
Indoor pollution analyte detection result shows that room air pollution degree is higher 4-8 times than outdoor；It is referred to as one of " four big stealth killers "
Formaldehyde mean concentration it is exceeded 6-7 times.Formaldehyde has stimulation to eye, mucous membrane and respiratory tract, can cause chronic respiratory disease
Disease, allergic rhinitis, immunologic function decline etc.；It is considered as potential carcinogen, it may be possible to rhinocarcinoma, throat cancer, cutaneum carcinoma
Inducement.According to statistics, the excess death toll that China is caused by room air pollution every year is up to 11.1 ten thousand people, excess outpatient service number 220,000
Person-time, 4,300,000 person-times of excess emergency treatment number.Solve artificial board formaldehyde release problem and arrive instant stage.
