Brick slips

Brick Earih. An impure loamy clay, particularly that of the Pleistocene of the Thames Valley, used for brickmaking. Brick Shapes. See Fig. 1 and the further references in Appendix A. The German didier CO publishes a detailed coding system for refractory bricks and shapes, which is a de facto standard in Europe. Brick Slip. A fired ceramic architectural facing varying from about 13 to 38mm in thickness and produced either as a unit itself or cut from a larger unit. 

Pistol Brick. Brick slips cut into L-shapes, to achieve decorative patterns. Piston Extruder. See stupid. 

The construction industry is now applying structural bonding, a method of structural fabrication used in the aircraft industry. It has been used for manufacturing prefabricated panels where brick slips, or other decorative lacings, are bonded to epoxide resin concrete backings. In the construction industry, wood, concrete, and other building materials are also bonded with adhesives. Table 2 shows examples of adhesives used in the construction applications. 

Conversely, if the concrete contractor is careless, and the braces of his forms slip, the weight of the concrete can bulge the wall inward at the center-perhaps not everywhere, but in only one short section. If this is not corrected, and if the membrane and brick are laid over this reverse curve, as the brick grow they will push into the tank, away from the supporting wall, so the brick will separate from the membrane and wall, and eventually fall in. 

The present global production of ceramic products is estimated at approx. 550 mill tpa, 365 mill t of these are contributed by bricks, roofing tiles and sewer pipes, which are nearly entirely extruded. Refractories, technical ceramics and tableware use extmders partly to form products or at least to prepare bats. So 70 % of the shaping of ceramics is executed to day in extruders, 28 % of the products are shaped from powders, and just 2 % are produced by slip casting. That shows how important extrusion is for the ceramics industry. 

This boundary was assumed to be a ground plane with zero magnetic vector potential. A constant heat flux of 5.5 kW/m was prescribed for the bottom, which is the measured cooling rate for this brick wall. For the momentum transfer, the bottom wall was regarded as a non-slip wall. 

Pick-up. The amount of vitreous enamel slip (expressed in terms of dry weight per unit area) after the dipping and draining process. For ground-coats, the pick-up is usually 350-450 g.m-2. Pickings. Term applied to clamp-fired STOCK BRICKS (q.v.) that are soft though of good shape. 

The reducing agent, NH3, is adsorbed onto the SCR and then consumed by NOx reduction reactions. The amount of ammonia fed to the reactor must be controlled depending on the operating conditions in order to maintain a high level of NH3 adsorption and NOx conversion of the SCR on the one hand. On the other hand, NH3 emissions from the aftertreatment system into the environment are not desired and have to be avoided. In order to reduce as much as possible the amount of released ammonia, the addition of another catalytic device downstream the SCR one can be an efficient and reliable solution. Furthermore, to maintain the system as compact as possible, one solution is to add an ammonia oxidation functionality directly in the rear part of an SCR monolith (Fig. 18.1a). In this way, an NH3 slip catalyst (ASC) is added after the SCR to oxidize NH3 leaving the SCR brick [2]. 

As effective clay modifiers, lignin dispersants can improve tile and casting slip rheology, rednce free water for brick extrusion, and provide Inbricity and plasticity for both extmded and dry-press ceramics. As a binder, lignin may increase both green and dry strengths of ceramic pieces with less than optimum body compositions.
