DESCRIPTION
This product is blending with foaming agent, foaming stabilizer, cleaning compound, emulsifier, permeation agent and many sort active agent etc..It is widely used in balance type shield tunneling machine .
¡ô It contains soil layer of clay: This product has low expansion rate, suggest the expansion rate is 6~15, thus it can has good lubricating effect .
¡ô Other soil layer : This product has high expansion rate, suggest the expansion rate is 25~36, so that spray thus formed foam to the frontal face of machine, capture the layer of soil, then discharges it together with dreggy soil .
APPLICATION
This product is colourless, non odour, contains non phosphorus, foam is abundant and persistent .It is multi-purpose foaming agent, can be used for additive of balance type shield tunneling machine operating on soft soil layer of clay . It is needed for controlling good operating condition .
¡ö Sealing and resisting to water .
¡ö Decreases friction force .
¡ö Decreases blocking of clay .
¡ö Increases resisting to water property of screw type conveyer .¡¡
