摘要:
This invention relates to a plant cube, comprising a block of mineral fibres, having a top surface, a bottom surface and four side surfaces, which block comprises a laminated structure of in parallel orientated mineral wool fibres, wherein preferably the laminated structure comprises substantially vertically orientated fibres, or wherein preferably the laminated structures comprises substantially horizontally orientated fibres.
摘要:
The invention relates to a growth substrate comprising at least one layer of short transversally extending mineral wool fibers and at least one surface layer of mineral wool fibers, wherein preferably the layer of short transversally extending mineral wool fibers is interposed between two surface layers of mineral wool fibers, or wherein preferably the layer of short transversally extending mineral wool fibers is interposed between two surface layers of horizontally extending mineral wool fibers.
摘要:
Mineral wool plant substrate formed of a coherent matrix of mineral wool having 99.9 to 75 wt % mineral wool and 0.1 to 25 wt % of an organic substance. Clay may be included in the matrix. The matrix may be in the form of a pellet.
摘要:
The invention relates to a plant growth substrate, comprising a coherent, hydrophilic matrix of mineral wool fibres mutually connected via binder based on furan resin, and to use of a coherent, hydrophilic matrix of mineral wool fibres mutually connected via binder based on furan resin, as a plant growth substrate.
摘要:
The present invention relates to a process for the manufacture of mineral wool plant growth substrate having a coherent hydrophilic matrix of mineral wool fibres connected by cured binder, comprising the steps of: providing mineral wool fibres; applying to the mineral wool fibres as a binder a phenol-formaldehyde resin and a furan resin; forming a matrix of the mineral wool fibres; and curing the binder and to the obtainable mineral wool plant growth substrate.
