Non-shrink grout is a hydraulic cement grout that, when hardened under stipulated test conditions, does not shrink, so its final volume is greater than or equal to the original installed volume. It is often used as a transfer medium between load-bearing members.
Grout sealer is a water-based or solvent-based sealant applied over dried grout that resists water, oil, and acid-based contaminants. Grout cleaner is a basic cleaning solution that is applied on grout lines and removes the dirt and dust. [9] A die grinder is used for faster removal of old grout compared to a standard grout saw.
Rust converter is usually applied to objects that are difficult to sand blast, such as vehicles, trailers, fences, iron railings, sheet metal, and the outside of storage tanks.
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [1] The IUPAC name for an epoxide group is an oxirane.
Paint remover is applied to an aircraft's landing gear during an inspection looking for cracks in the aluminum. Paint stripper or paint remover is a chemical product designed to remove paint, finishes, and coatings, while also cleaning the underlying surface. Chemical paint removers are advantageous because they act on any kind of geometry and ...
Service laterals, where present, can be reconnected from within the newly-formed larger-diameter pipe, by cutting replacement openings using robotically controlled cutting devices, then sealed using specially-designed CIPP materials referred to as 'top-hats'. The resins used are typically polyester for mainline lining and epoxy for lateral lines.
Dry etching refers to the removal of material, typically a masked pattern of semiconductor material, by exposing the material to a bombardment of ions (usually a plasma of reactive gases such as fluorocarbons, oxygen, chlorine, boron trichloride; sometimes with addition of nitrogen, argon, helium and other gases) that dislodge portions of the material from the exposed surface.
The NY 9X designation has been used for two distinct highways: The first NY 9X was a loop route connecting US 9 to Saratoga Lake southeast of Saratoga Springs. It was assigned c. 1931 [40] [60] and renumbered to NY 9P c. 1936. [55] [62] The second NY 9X was an alternate route of US 9 through New York City in the vicinity of the Harlem River.
