蘭州建筑工地防塵網

建筑工地防塵網也叫高阻燃防塵網、煤場阻燃抑塵墻、高強度防塵網，具有阻燃性具有抗日光、火、熱、霜凍、霉變、腐爛、酸、堿、鹽等特性，耐用性好，使用壽命長達20年；其特別設計的孔隙既能隨風產生自凈功能，以避免粉塵積累，又能實現比實體墻更好的抑塵效果：經風洞試驗表明最佳起塵抑制率可達90％；同時抑塵網鋼架架構簡單、節約鋼材、從而造價更低。

擋風抑塵的原理：

風(feng)(feng)(feng)(feng)(feng)(feng)(feng)能(neng)(neng)是衡量風(feng)(feng)(feng)(feng)(feng)(feng)(feng)將(jiang)物料（或(huo)(huo)料堆）中(zhong)粉(fen)塵(chen)(chen)(chen)(chen)吹(chui)走（或(huo)(huo)揚起）的能(neng)(neng)力。風(feng)(feng)(feng)(feng)(feng)(feng)(feng)速(su)越(yue)高(gao)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)能(neng)(neng)越(yue)大，風(feng)(feng)(feng)(feng)(feng)(feng)(feng)速(su)越(yue)低風(feng)(feng)(feng)(feng)(feng)(feng)(feng)能(neng)(neng)越(yue)小。以擋(dang)塵(chen)(chen)(chen)(chen)網(wang)(wang)將(jiang)網(wang)(wang)下游(you)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)速(su)降至40%為(wei)例(li)，此(ci)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)速(su)之(zhi)(zhi)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)能(neng)(neng)僅為(wei)上游(you)來風(feng)(feng)(feng)(feng)(feng)(feng)(feng)的16%。換(huan)言之(zhi)(zhi)，風(feng)(feng)(feng)(feng)(feng)(feng)(feng)能(neng)(neng)降低了84%。以12米(mi)高(gao)擋(dang)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)抑塵(chen)(chen)(chen)(chen)網(wang)(wang)，風(feng)(feng)(feng)(feng)(feng)(feng)(feng)速(su)七(qi)～八級為(wei)例(li)，在此(ci)網(wang)(wang)下游(you)約180m范圍內，只形成微(wei)弱、均勻、平直、穩定的氣流，不易形成渦流和垂直運動的氣流，故粉(fen)塵(chen)(chen)(chen)(chen)不易被揚起，從而(er)達到擋(dang)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)抑塵(chen)(chen)(chen)(chen)的目的。
