Abstract
Mineral wool product are disclosed. In one example, the mineral wool product can include mineral fibers bound by a binder resulting from the curing of a binder composition that includes a phenol-formaldehyde-based resin, and/or a carbohydrate containing component. Methods of inhibiting corrosion when insulating a metallic structure are also disclosed.
Claims21
A method of inhibiting corrosion when insulating a metallic structure, wherein the method comprises:
- insulating the metallic structure with a mineral wool insulation product resulting from a process comprising:
- contacting mineral fibers with a binder composition comprising a phenol-formaldehyde-based resin and/or a carbohydrate-containing component;
- also contacting the mineral fibers with a hydrophobic agent comprising a silicone compound and a silane, wherein the hydrophobic agent is present in an amount of 0.05 to 2 percent by weight based on the weight of the mineral wool insulation product;
- and
- curing the binder composition;
- wherein the mineral wool insulation product has a water absorption according to EN13472 of less than 1.0 kg/m2 following storage of the mineral wool insulation product at 250 degrees centigrade for 24 hours;
- wherein the metallic structure undergoes cyclic temperature changes during operation;
- and
- wherein, as a result of the water absorption of the mineral wool insulation product, the metallic structure undergoes reduced corrosion due to the mineral wool insulation product reducing contact of water with the metallic structure relative to a mineral wool product without the hydrophobic agent.
A method of inhibiting corrosion when insulating a metallic structure, wherein the method comprises:
- insulating the metallic structure with a mineral wool insulation product resulting from a process comprising:
- contacting mineral fibers with a binder composition consisting essentially of a phenol-formaldehyde-based resin;
- also contacting the mineral fibers with a hydrophobic agent comprising a silicone compound and a silane, wherein the hydrophobic agent is present in an amount of 0.05 to 2 percent by weight based on the weight of the mineral wool insulation product;
- and
- curing the binder composition;
- wherein the mineral wool insulation product has a water absorption according to EN13472 of less than 1.0 kg/m2 following storage of the mineral wool insulation product at 250 degrees centigrade for 24 hours;
- wherein the metallic structure undergoes cyclic temperature changes during operation;
- and
- wherein, as a result of the water absorption of the mineral wool insulation product, the metallic structure undergoes reduced corrosion due to the mineral wool insulation product reducing contact of water with the metallic structure relative to a mineral wool product without the hydrophobic agent.
A mineral wool insulation product for insulating a metallic structure while inhibiting corrosion under the mineral wool insulation product, the mineral wool insulation product comprising:
- mineral wool fibers;
- and
- a cured binder composition binding the mineral wool fibers, the cured binder composition resulting from curing a phenol-formaldehyde-based resin and/or a carbohydrate-containing component;
- and
- a hydrophobic agent comprising a silicone compound that is not a silicone resin.
