摘要:
A multilayered composite material comprises as components: (A) a sheet material, (B) a material capable of absorbing water or aqueous fluids, (C) at least one bonding layer and (D) a polyurethane layer with capillaries passing through the entire thickness of the polyurethane layer, wherein the polyurethane layer (D) comes into direct contact with sheet material (A) or absorption-capable material (B) in one or more places.

摘要:
Water soluble radiation curable products (A) obtainable by mixing mixing with or without reaction of at least one hyperbranched polyurethane (a) with at least one photoinitiator (b) or by synthesis of at least one hyperbranched polyurethane (a) in the presence of at least one photoinitiator (b), are used to produce aqueous inks for the ink jet process.
摘要:
Aqueous dispersions comprising (A) at least one polyurethane, (B) at least one compound of the general formula I a or I b in which R1, R2 and R3 may be identical or different and are selected from A1-NCO and A1-NH—CO—X, in which A1 is a spacer having 2 to 20 carbon atoms and X is selected from O(AO)xR4, AO is C2-C4-alkylene oxide, x is an integer in the range from 1 to 50 and R4 is selected from hydrogen and C1-C30-alkyl, (C) and at least one silicone compound having reactive groups.
摘要:
A system for protecting stored goods in a container (10), comprises a cage-like structure (20) formed by at least one pesticide treated net (22), capable of enclosing the stored goods, wherein the cage like structure (20), further comprises means for suspending the pesticide treated nets (14, 28, 30, 32, 34), and means for opening and closing the cage-like structure (26) on at least one section (24) of the at least one net (22). The system is particularly useful for the transport of tobacco, coffee, dried fruits, cocoa, nuts, tea, cereals, vegetables, spices and animals.
摘要:
A system for protecting stored goods in a storage room, having one or more storage constructions formed by one or more pesticide treated nets (30, 31), capable of enclosing the stored goods, where the storage construction further includes a support frame, means for suspending the support frame, means for opening and closing at least one section of the storage construction while the support frame is in a suspended state, and means for avoiding an overall structural collapse if a net gets entangled. The system is particularly useful for the storage of tobacco, coffee, dried fruits, cocoa, nuts, tea, cereals and spices.
