Asbestos fibre dust binding - using combination of calcium chloride soln. and calcium chloride paste

摘要

Claimed are (i) a calcium chloride soln. with a wetting agent and further components for fibre-binding in combination with a calcium chloride application paste, used for binding asbestos fibre dust during clearance work; (ii) a spray nozzle for introducing the soln. into the asbestos material; (iii) a penetrating tool for demolishing plaster surface to allow the spray nozzle to introduce the soln. into the asbestos material behind the plaster; (iv) a collection tank with a suction device, bagging device and working height adjuster; (v) a special bag with a printed warning, for dumping the asbestos-contg. waste; and (vi) a change-over slide device allowing distribution or application of the soln. or the paste by a pump unit. ADVANTAGE - The soln. and paste combination and the equipment provide reliable binding of the fibres to protect workers and the environment.
