METHOD FOR QUALITY EVALUATING OF ROCK WOOL FOR USE IN ROCK WOOL SPRAY AND ROCK WOOL SPRAY METHOD
To provide a rock wool evaluation method for selecting rock wool with less dust generated when rock wool is sprayed by the semi-dry method, and to provide a rock wool spray method that generates less dust during the spraying of rock wool.MEANS: A method of evaluating the quality of rock wool, comprising the steps: (a) rock wool is sucked into a specific dust collector 1 from the tip 14 of a hose 12 connected to the collector; (b) the sucked rock wool is introduced into a tank 2 having an opening 16 covered by a filter 6 through which sucked air is discharged; (c) the mass of the rock wool collected in the tank of the dust collector (RWT) and the mass of the rock wool adhering to the filter (RWF) are measured; and (d) the mass ratio of rock wool collected in the tank to the rock wool adhered to the filter is calculated to evaluate the quality of the rock wool.SELECTED DRAWING: Figure 1
【課題】半乾式工法によるロックウール吹付け時に発生する粉塵が少ないロックウールを選定するためのロックウール評価方法を提案すること。また、ロックウール吹付け時に発生する粉塵が少ないロックウール吹付け工法を提供すること。【手段】ホースを接続した特定の集塵機を用いてホース先端よりロックウールを集塵機に吸い込ませ、集塵機のタンク内で回収されたロックウールの質量（ＲＷＴ）と前記フィルターに付着したロックウールの質量（ＲＷＦ）とを測定し、タンクとフィルターでそれぞれ回収されたロックウールの質量比率を求める。【選択図】図１
