EN 14879-5:2007 (E) 5 1 Scope This document describes the requirements for and methods of testing of organic linings which are applied to concrete process engineering equipment that wil

25、l come in contact with aggressive chemical substances (liquids, solids and gases). The requirements specified here may be used for the purposes of quality control (e.g. as agreed between the contract partners). The standard applies to linings which serve one or more of the following purposes: to pro

26、tect the component from damaging effects of aggressive substances; to protect waters (e.g. ground water) from harmful substances; to protect the charge from becoming contaminated by components released from the substrate material; to achieve a particular surface quality. The different lining systems

27、 are: a) bonded linings; b) mechanically fixed linings; c) loose linings of sheeting material; d) loose linings of pre-formed pieces or lining units. Handling of aggressive or water pollutant materials is understood to include e) storage; f) filling; g) loading and unloading; h) manufacture; i) trea

28、tment; j) use. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

40、 and definitions given in EN 14879-1:2005 and the following apply. NOTE The terms used to designate structural elements requiring surface protection are usually based on the function of the elements in the process plant. For the sake of consistency, the most common of these elements are referred to

41、here on the basis of their function within the structure. 3.1 floor (bottom) flat or inclined surface, such as the floor of a production or storage area, and the bottom of a vessel 3.2 wall vertical or almost vertical limiting surface, such as the wall of a production and storage area, and the wall

42、of a vessel 3.3 ceiling (top) upper limiting surface, such as the ceiling of a production and storage area, and the top of a vessel 3.4 gutter open indentation, moulded in the floor, through which fluids may drain away 3.5 trench open or covered element in the floor of any shape or size, whose inver

43、t is considerably lower than the floor, and through which fluids may drain away 3.6 pipe hollow cylinder of any shape or size, through which fluids, gases and vapours may pass 3.7 sump depression in the floor, designed as the lowest point from which collected substances can be drained off EN 14879-5

45、essel and tank 4 Concepts and selection criteria 4.1 Surface protection types and systems 4.1.1 General Surface protection is usually applied as a lining as in 4.1.2 and Clause 5, as a coating as in EN 14879-3 or as a composite coating or lining system as in prEN 14879-6. The last of these combines

46、a chemically resistant sealing coat with a wearing layer. 4.1.2 Protective linings Linings based on organic binders, such as a) Bonded linings Bonded linings comprise pre-fabricated sheets that are fixed to the substrate by means of an adhesive applied over the entire surface area. The sheets are th

47、en jointed using an adhesive or by welding. b) Mechanically fixed linings Linings made of thermoplastic units (e.g. sheets, slabs or pre-formed pieces) that are fixed to the concrete substrate by means of fasteners systematically arranged on the units underside. The lining units are then jointed by

48、welding. These linings may be applied either during the construction of the concrete member or after construction has been completed, in which case the lining is attached to a layer of facing concrete. c) Loose linings of sheeting material Pre-fabricated linings that are laid loosely on the substrat

49、e, jointed and then fixed to the walls by means of metal beads, for example. The sheets are usually surfaced with gravel or screed, or protected against exposure to sunlight, warping and mechanical damage by means of a masonry facing. d) Loose linings of pre-formed pieces or linings units Linings made of pre-formed pieces laid in the concrete member and then fixed or welded at the top edge, if necessary.
