The present invention relates to a water-soluble pre-reacted binder composition, a method of its manufacture, a use of said pre-reacted binder composition, a method of manufacturing a collection of matter bound by a polymeric binder, a binder solution or dispersion comprising said pre-reacted binder composition, as well as products comprising the pre-reacted binder composition in a cured state.

Provided are a preparation method of a silica aerogel-containing blanket which includes mixing a water glass solution, a polar organic solvent, and a silazane-based surface modifier to prepare a sol, preparing a silica gel-base material composite by immersion and gelation of a base material for a blanket in the sol, and drying the silica gel-base material composite, and a silica aerogel-containing blanket prepared by using the preparation method.

A silica aerogel-containing blanket having a high degree of hydrophobicity as well as excellent physical properties, particularly, low tap density, high porosity, and excellent mechanical flexibility may be prepared by the minimal use of a surface modifier without a surface modification step by the above method.

The reinforced removable thermal insulation (PARTS) contains the heat-insulating blocks joined among themselves placed on an external surface of the heat-isolated equipment. The Asti block is filled with heat-insulating material and consists of a reinforcing frame lattice sheathed on all sides with facing stainless sheets. For mutual detachable connection of heat-insulating blocks between themselves the lock latch is used. When using the proposed lock-latch, a guaranteed tightness is provided, the disclosure of thermal gaps between the side faces of thermal insulation blocks from the inaccessible internal bases of thermal insulation at temperature fluctuations is excluded, fitting works and welding of tension locks on the surface of their blocks in place during installation and Assembly work on the equipment are excluded. Asti blocks are able to save the weight of stainless steel, increase the strength of thermal insulation blocks by 2.56 times, significantly reduce the cost of their manufacture.

Representative implementations of devices and techniques provide an exemplary protective insulation system that includes a heating element. The protective insulation system includes a substrate layer and may include a protective layer over the substrate layer. The protective insulation system is lightweight and can be installed with minimal manpower and equipment.

Exhaust insulation systems and methods are described that include multiple layers. In one example, a system includes a base insulation layer covering a portion of an exhaust pipe and a hard outer cover formed from a spirally wrapped knit tape and having a length coextensive with the length of the underlying base insulation layer. The wrapped knit tape outer cover can include successive turns of tape overlapping by 25% to 75%. The knit tape can be impregnated with a thermosetting phenolic resin prior to being wrapped about the pipe.

An insulation product is disclosed comprising a plurality of glass fibers; and a cross-linked formaldehyde-free binder composition at least partially coating the glass fibers. The glass fibers have an average fiber diameter in the range of 8 HT (2.03 μm) to 15 HT (3.81 μm). At a density (x) between 0.3 pcf and 1.6 pcf, the insulation product may achieve a thermal conductivity (y) less than or equal to that which satisfies Formula (III):

y=0.116x.sup.2−0.3002x+0.4219.  Formula (III):

A mineral wool product comprises mineral fibers bound by a binder resulting from the curing of a binder composition comprising a phenol-formaldehyde-based resin, and/or a carbohydrate containing component; a hydrophobic agent comprising (i) at least one silicone compound, such as silicone resin; (ii) at least one hardener, such as silane; (iii) optionally, at least one emulsifier; as insulation of a metallic structure, said structure having an operating temperature between 0-650° C.

A device for securing at least one thermal protection mat to an internal fixed structure of a nacelle includes at least one removable fastening element for securing the at least one thermal protection mat to the internal fixed structure designed to be arranged between the mat and the internal fixed structure. The device includes at least one gripping element connected to the removable fastening element to project relative to the mat on the opposite side to the internal fixed structure, the removable fastening element being intended to be detached from the internal fixed structure by a pulling force exerted on the gripping element.

A concentric, multi-layer laminated wrap for protection of plastic pipes including up to 60-minute fire endurance, low flame spread, low smoke, and toxic products of combustion. The laminated wrap can withstand temperatures up to 2000° F. for up to a period of 60 minutes. The concentric laminated wrap includes an inner support layer that provides strength, an intermediate fire protective coating layer that provides fire, heat, and high temperature protection, and an outer top coating layer that provides resistance to abrasion, impact, and environmental factors including water, salt water, hydrocarbons, chemicals, and gases. The protection to plastic pipes and pipe appliances is provided by the fire protective coating layer that is applied directly to the pipe or as a layer in the laminated wrap around the pipe. The present invention is disclosed for fire, heat, and high temperature protection of pipes, including linear pipes and pipe appliances such as flanges, couplings, valves, joints, tees, and bends.

A mineral wool product comprises mineral fibers bound by a binder resulting from the curing of a binder composition comprising a phenol-formaldehyde-based resin, and/or a carbohydrate containing component; a hydrophobic agent comprising (i) at least one silicone compound, such as silicone resin; (ii) at least one hardener, such as silane; (iii) optionally, at least one emulsifier; as insulation of a metallic structure, said structure having an operating temperature between 0-650° C.
