摘要:
Ein Verfahren zum Befestigen von Landflächen (1), deren Boden durch Erosion gefährdet oder zerstört ist, besteht vor allem darin, eine pumpfähige Masse (2) aufzutragen, welche als Keimboden oder Keimschicht für Pflanzen (3) geeignet ist . Dazu wird vorgeschlagen, Holz, insbesondere mechanischthermisch zu zerfasern, wobei Holzfasern mit einer solchen Länge gebildet werden, daß sie miteinander verfilzt werden können, um auch aufgrund des natürlichen Harzes aus dem Holz gut miteinander vernetzt zu sein, sich aber auch an der Bodenfläche mit entsprechenden Holzfaserenden verankern läßt. Die Holzfasern werden zur Bildung der pumpfähigen Masse (2) mit Wasser gemischt, so daß diese pumpfähige Masse manuell oder naschinell aufgetragen werden kann.
摘要:
A sprayable composition and a method of protecting material with the composition is disclosed. The composition comprises a polymer such as hydroxyethyl cellulose, clay, and water to provide a cover layer which, after spraying, is tough, flexible and water-repellent. Other materials such as shredded paper and gypsum can be used in the cover layer. The composition is effective as a cover layer over material such as soil, refuse at a dump site, or grain in a stockpile.
摘要:
A liquid mulch for providing a protective crust comprises an aqueous composition comprising:
a polymeric binder; and per 100 parts by weight of said binder, about 100 to about 1600 parts by weight of suitable particulate filler; said aqueous composition having a solids level of not less than about 30 (optionally about 30 to about 85) per cent by weight. The liquid mulch can be applied to a domain (e.g. an agricultural domain) so as to provide a dry coat weight of about 33.5 to 1674 g/m 2 . Crop production can be enhanced by said application.

摘要:
Apparatus for making a low density fibrous mat for use as a self-contained support system to enhance the growth and probability of survival of an established seedling or a viable seed which has at least two adjoining layers of lignocellulose fibers bonded together by an adhesive of the type weakened by exposure to an outdoor environment. The apparatus is characterized by a pneumatic fiber conveying and depositing means in which the pneumatic conveyor is charged by rotatable tined shafts above a screw-conveyor and a following belt conveyor from which the fibers are drawn into the pneumatic conveying system for eventual deposition on a continuous vacuum screen.
摘要:
The present invention relates to methods of improving germination rates of plants or crops, and of preventing or arresting water evaporation loss from targeted soil areas by use of soil additives, which allow for improved water utilization by crops, plants, grasses, vegetation, etc.

摘要:
The invention relates to a material used as thermal and/or sound insulation material, consisting essentially of microfibers from stem fibers of banana fruit trees. Said material has surprising sound and thermal insulation properties, and more particularly heat and cold resistance properties.
