Description
Technical field
The present invention relates to a kind of preparation method of environmentally friendly dust suppressant, the dust suppressant is with nontoxic, environment is friendly
Good, feature low in cost and high-efficient dust suppression.
Background technique
Dust pollution is one of the main composition of current air pollution, dust suppressant occurs from the middle of last century, at present
It is constantly subjected to the concern of people.The dust suppressant of commercialization mainly includes the Dus-con company of South Korea, the GE Betz company in the U.S.,
The RST company of Australia, the chemical dust suppressant of the companies such as Dutch Wuvio and German BASF production, can according to dust suppression mechanism
To be divided into moist type chemical dust suppressant, binding type chemical dust suppressant, coagulation type chemical dust suppressant and Compound chemical dust suppressant.Its
The effects of middle binding type chemical dust suppressant is by covering, bonding, silication and polymerization, can inhibit dust and dust etc., have
The advantages that anti-dust effect is good, and raw material is easy to get, and cost of material is low, and production technology is mature is widely used in construction site and road surface etc.
Place.However, similar with other chemical dust suppressants, there is degradation hardly possible and cause secondary pollution problems to environment in such dust suppressant.
In addition, there is also practical operation difficulty, the problem of emulsifying effectiveness difference.
Currently, with the development of social progress and society, demand of the people to goods and materials is higher and higher, thus to health
Attention degree is also growing day by day, and in order to improve the pollution of dust at present atmosphere, previous chemical dust suppressant is more and more not
It is able to satisfy people's requirement, gradually environmental-friendly dust suppressant without secondary pollution development.By finding from a wealth of sources, cheap original
Material, it is current trend that the New Dust-Depressor of various mal-conditions can be resisted by, which developing,.Recently, both at home and abroad with regard to environmental type
Dust suppressant expands a series of research work, wherein the Suaeda salsa seedcake of the exploitations such as Nankai University Ji Ya celery is primary raw material
Dust suppressant to good moisture retention and water stability, every square metre of cost is 0.5 yuan.The research and development such as Qingdao Agricultural University's Sui Fang function
The New Dust-Depressor based on marine algae extract, every square metre of cost is 0.1 yuan.Therefore, the present invention is by combining the Chinese Academy of Sciences
Research and development advantage of the littoral zone research institute in terms of algae is extracted with environmentally friendly dust suppressant, developing low-cost efficiently novel suppression
Dust agent.
