substrate intended to support culture and application to the performance of sports surfaces in particular

摘要

substrate for use as a culture medium, and substrate application. a substrate for use as a culture support comprising: a first portion, which forms the substrate backbone and represents more than 70% of the total volume of said substrate, composed of p 100pm particles having a particle size greater than 100 µm one, all said particles consisting of hard particles of ph 100 and / or resilient particles pr 100, wherein said resilient particles become a volume ratio vv of between 0% and 100% by volume of this first part; a second part of p 100 corpuscular components having a particle size of less than 100 µm, and consisting of 0-450 g / l of said substrate; a third part becoming 0-200 µl of said thin fiber substrate which is between 3 mm and 100 mm in length and between 5 µm and 35 µm in diameter; a fourth part, becoming 0-200 g / l of said substrate, composed of other elongated and / or surface inclusions, at least one of the dimensions of each of these elongated inclusions or surface being much larger than size particle size of the first part, wherein the sum of the third part and fourth part amounts are greater than 3 g / l of said substrate. use for grooming, in particular turfed sport surfaces and balcony construction.
