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:
The invention relates to an object having at least one opening through which an air flow is guided, characterized in that the respective opening is covered on the visible side with a visually appealing air-permeable or breathable membrane which the gas flow passes, wherein the membrane comprises at least two layers, of which one comprises at least one polyurethane and is provided with a patterning.
摘要:
The invention relates to aqueous dispersions comprising (A) at least one polyurethane, (B) at least one compound of the general formula I a or I b (I a) (I b), wherein R1, R2 and R3 may be identical or different and are selected from A1-NCO and A1-NH-CO-X, wherein A1 is a spacer having 2 to 20 carbons atoms and X is selected as 0(AO)xR4, AO is C2-C4-alkyleneoxide, 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 silicon compound with reactive groups.
摘要:
A system for protecting stored goods (50) in a storage room (1), comprises one or more storage constructions (2) formed by one or more pesticide treated nets (30, 31), capable of enclosing the stored goods (50), wherein the storage construction (2) further comprises a support frame (10), means for suspending the support frame (35), means for opening and closing at least one section (13) of the storage construction (2) while the support frame (10) is in a suspended state, and means for avoiding an overall structural collapse (32) if a net (30, 31) gets entangled. The system is particularly useful for the storage of tobacco, coffee, dried fruits, cocoa, nuts, tea, cereals and spices
