Shanxi Hande environment project science and technology development limited company had been established in 1998, is engaged in the environmental pollution government specially the specialized company, is the Shanxi environment and economical development promotion agency's vice-chairman the unit, mainly is engaged in raises dust environmental protection project and so on pollution government, coked waste water processing. The company develops the development "the HANDE sign" to keep out the wind the dust suppression wall, is in view of each kind of dump site and so on coal field, open-air materials yard raises the dust pollution to govern the most advanced dust suppression technology at present, the dust suppression effect achieved above 80%, the product through the provincial level quality engineering supervision bureau product examination, has the honor to receive "the Shanxi Province recommendation environmental protection product" and the nation "the quality, the prestige double safeguard demonstration unit" .

　　 The company technical force is abundant, with scientific research institution cooperation and so on domestic the university, has most advanced keeps out the wind the dust suppression wall product and the technical research and development center, the company has the project specialized technical personnel 24 people at present, senior engineer 6 people, environment engineer 8 people. Chief technical expert Professor Zhang Zuoguang is postgraduate candidate teacher, holds a concurrent post Chinese compound materials academic society routine director concurrently assistant deputy secretary-general, Chinese Society of Aeronautics and Astronautics tree fatty group compound materials specialized committee director, has the national monopoly 5 items. At the same time the company also has the large-scale OEM product production base, uses the advanced import to keep out the wind the dust suppression wall production assembly line, is the ISO9001 international quality system authentication enterprise, the company subordinate Milky Way steel structure company mainly is engaged in metal arched roof the and so on the steel structure, wire table, great span dry coal awning design, the manufacture and the installment. Has home most advanced H to be heavy /light steel production line, the arched roof takes shape the unit, throws the pill to eliminate the rust equipment, the high pressure spurts spreads gathers the ammonia fat and the ultrasonic testing instrumentation. It "the metal arch ripple roof design, the manufacture, installs the engineering research" through the ministry of construction science and technology achievement appraisal, the fill domestic blank, is in the lead the international standard.

　　 Your difficult problem, my topic, we by "high quality, specialized, highly effective" the management idea, provides the high-quality service for the general customers, contributes labor and materials for China's environmental protection enterprise.

"HANDE suppression wall against wind and dust " use the great span the steel structure, the standard 6 meters one cross, front door 9 meter, 12 meters one cross, not only the structure stable is reliable, moreover reduced the project construction cost greatly, the chart has kept out the wind and the dust suppression wall steel structure for the international telegram electric power .

"HANDE suppression wall against wind and dust " to use the new high polymer inorganic nonmetallic compound materials, the use aerodynamics principle, when causes the circulation the air (gale) from outside through the wall, forms the air current in the wall inside which on, under disturbs by to achieve the flank gale, the inside weak wind, the flank breeze, the inside calm effect, the dust suppression rate reaches above 80 % about.

"The HANDE sign" suppression board agaist wind and dust in originally "the third generation anti- booklet" in the foundation has made the massive improvements, uses the high polymer compound materials, suppresses after the large-scale machinery but becomes, has is flame-resistant, the anti- aging, the good flexibility, degree of hardness, the color is artistic and so on the characteristic, is suitable temperature 80 ℃ ~ -40 ℃ , above service life 20 years. The product obtains the title in China the light product quality safeguard center "the quality, the prestige double safeguard demonstration unit" and Shanxi Province "the recommendation environmental protection product". The chart for installs the scene.
