摘要:
Compositions for application to a soil for retaining water in the soil for plants are prepared by applying an aqueous solution containing sodium and/or potassium methylsiliconate to a substrate so that the siliconate applied is in an amount of between 180 g and 1,000 g per m.sup.3 substrate and then, the treated substrate is allowed to dry at ambient temperature. The substrates employed include tree bark, sawdust, compost and vegetable mould and also gravel and sand. Additionally, porous articles prepared for containing plants also may be treated for improving retention of water.
摘要:
A method for treating siliceous and carbon central structures with a water repellant composition wherein an effective amount of water repellant composition is dispersed in water and the mixture then is applied in a continuous process after the mixing to the structure to be treated. The methods also contemplate increasing the depth of penetration of a silane into the structure to be treated by applying subsequent applications of silane to the structure to be treated.
