Abstract: Ten functions of brick: load bearing, heat insulation, sound insulation, anti-vibration, anti-shear ability, leak-proof mortar, wall anti-leakage, blocking gray bridge. The Functional Superiority of the New Multifunctional Molding Machine Compared to the Vacuum Extruder.

　　1 Introduction

　　Compared with the existing extruder, the new fully automatic multi-functional molding machine in the production, quality and energy saving and other aspects have a comparable bright spot. The machine has the advantages of reasonable theory, simple manufacturing process, convenient installation and maintenance, and multi-machine and multi-function models corresponding to various types of brickworks. The T-shaped porous bricks produced by this machine have advantages.

　　2.New Characteristics of Sintered T - type Porous Function

　　The following T-shaped porous function of its sintered brick with load-bearing, insulation, insulation, noise, anti-vibration, shear resistance, leakage-free mortar, anti-leakage, blocking gray bridge, decorative and other multi-functional As follows.

　　2.1 load-bearing

　　Brick load-bearing body is its first function, whether it is building wall load-bearing or filled wall should have a certain load capacity, brick building brick body must have a certain bearing capacity. National standard small and medium-sized porous brick to KP1 type, for example, compressive strength required to reach 20MPa. The existing standards than the EU standard 40MPa is far lower. The load-bearing value of the brick body is related to the overall life of the building, and the root cause of the low load-bearing value is that the compactness of the brick body is not enough. The compressive strength of the porous brick produced by the existing extruder comes from the load-bearing capacity of the brick wall, brick ribs did not play the role of compression, this is because the extruder extruded at the same time, Stretching, ribs through the movement, often have a crack, so its small bearing capacity, which is the production of extruder brick defect.

　　New multi-functional molding machine brick molding, because of its brick material down to the mold box, cover the mold box on both the push plate, the overall raw material in the mold box is loose, and push the plate in the core, When the upper and lower pusher plates act on the slopes of the upper and lower slopes (to a certain angle size), the slabs are pushed by the upper and lower pushers to push the middle pusher, To form. Brick walls and ribs at the same time force, and thus get the same density. So brick ribs will not break, while the brick launch, the walls are driven by more to increase the density of brick, so the porous brick ribs in the compressive strength of brick play a multiplier effect. Because the brick ribs and walls of the carrying area is almost equal, brick in the firing, the ribs and walls without cracks. Extruder brick extrusion not only a few cracks on the walls, rib ribs on the crack, so ribs do not play the role of load-bearing. New multi-functional molding machine brick after drying in the roasting process, almost do not see the crack, the yield in more than 99%. Because it is a single billet molding, pressure, and raw material moisture content of about 10%, the same blank body material to KP1 brick as an example: the general extrusion brick material used in 4.25kg, the hole rate of 25% The T-type porous brick material used in the 4.5kg, while the hole rate is 33%, so its density must be higher than the extruder brick, compressive strength will be doubled.

　　Manufacturers in the production of ordinary brick, it can also be used T-hole, its compressive strength is not affected, thus saving a lot of raw materials. Because of its pore structure of the bearing capacity of the pressure and the strength of the structure of ribs uniformity, can achieve the national standard, and played a relatively insulation effect.

　　2.2 insulation, heat insulation, noise

　　Brick insulation, heat insulation, noise three functions similar to, almost the same, winter insulation, summer insulation, usually noise. KP1 type porous brick, for example, T-shaped porous brick design and hole structure shown in Figure 1.

　　As can be seen from Fig. 1, the T-shaped and cross-shaped holes of the perforated brick are arranged in an orderly staggered arrangement with four wall thicknesses of 15mm, ribs of 10mm, holes of 10mm and holes of 40mm. Its biggest advantage is insulation, insulation, sound insulation effect, because of its cold bridge path length, the vertical length of the brick 240mm, conduction path 560mm, lateral 115mm, conduction path 169mm, thermal conductivity 0.21%, air in 8mm? 10mm Of the width and length of 10mm ~ 40mm length is static, the air does not flow does not produce heat conduction, in the case of hollow air and convection blocking the hot and cold air, its two layers of space are 8mm? 10mm, because of its conduction path Long, high porosity, hollow hole is, so the three functions is better than the current strip and other porous porous bricks.

　　2.3 Earthquake, anti-shear capacity

　　The two functions in the wall masonry after forming its performance is the same, T-shaped porous brick in the process of molding, the brick body has a groove, T-type structure 3mm deep, the middle 8mm diameter hole, the In the drying and drying when the ventilation to get rid of smoke when walking in the masonry, this side up, because of its T-shaped groove and the hole diameter of 8mm, masonry mortar covered, the combination of the upper and lower layers, It plays the role of pin joints, so that each layer of the wall fully integrated, play to enhance the shock, shear capacity, in earthquake-prone areas, can enhance the building seismic level multiplied, this outstanding performance, more Enhanced the overall effect of the wall housing, the life of the building and anti-risk ability, which played a very positive role.

　　2.4 Leak-free mortar

　　T-shaped porous bricks in the process of forming the top cover plate, with T-shaped groove, there are shaped with the following T-shaped hole corresponding to the depth of 3mm groove, see Figure 1, the hole for the vertical hole, The above is closed, so the laying of mortar in the masonry laying mortar will not leak.

　　2.5 anti-leakage

　　T-shaped porous brick masonry walls can prevent rain water leakage, because each layer of masonry when the level is sealed. At present, the water wall of water wall surface water seepage is a common phenomenon, the rain will be along the porous brick vertical hole concentrated to the bottom of the wall, the rainy season in the south, a two-story house is particularly affected. T-type porous brick to do the top of each brick can be sealed, so it will not seepage.

　　2.6 block the gray cold bridge

　　This performance has a certain technical content, and the existing extruder is unable to do, sintered T-shaped porous multi-functional block in Figure 2

　　T-shaped porous blocks in the molding at the same time, up and down the push plate at both ends with raised ribs: high 4mm, width 10mm, each end of the two ribs, the middle 10mm air chamber, the masonry, Upper and lower cross-mouth and left and right vertical gray mouth are more than 4mm with ribs of the air cavity, used to block the cross gray and vertical ash mouth, the middle wall of the wall still have 10mm gray mortar, This is an innovation for the sintering of large blocks of porous, so that the wall masonry blocking the gray bridge cold bridge to a breakthrough, thereby building insulation performance has been improved.

　　2.7 can be decorative

　　T-shaped porous brick in the process of molding can be printed directly to the pattern, the method is: in each mold box is equipped with a printing template, printing template can be replaced. The raw material in the mold box, through the operation of the machine squeeze, press, push the role of printing patterns can be presented along with the porous brick surface, through the oblique track molding, and after the wave with orbital regulator, Plasticity and density to a certain degree of ruggedness, and then run to the bottom of the machine, through the oblique track to the brick with the printing template together with the introduction of mold box, fell with a blank board conveyor belt, transported to the sorting institutions.

　　3 new multi-function molding machine and the extruder compared to the results

　　Extruder general power in the 100kW ~ 400kW or more, high-power at 500kW or so, people have repeatedly pursued high-power and hard plastic, its purpose is to high yield, brick solid, good shape, high yield. But the attendant problem is the cylinder, auger, spiral blade and the billet mouth wear increased, power consumption increased. A brick factory is profitable, the key is the product power consumption, the reason why the efficiency of brick is low, the main reason is the low value-added products, energy consumption, labor costs. Medium and small round kiln brick factory automation degree is low, in the market is more competitive, so he is a high energy consumption, low output, labor-intensive industries. How to change this situation, keep pace with the times. Automatic porous multi-functional one-time molding machine production line will be able to solve this problem, the machine automation performance, as shown in Figure 4.

　　New multi-functional machine in the energy-saving aspects, the power consumption of 7.5kW? 22kW, including several models of brick machine, its power consumption is less than the power of extruder vacuum chestnut, is a general vacuum extruder Electricity 1/10? 1/30, water, labor province, to reduce the drying area. A billet can stack 1.5m high, about 10% moisture content of brick, high yield, 10000 ~ 25000 pieces per hour, ordinary brick, high value-added products, this superior performance will give the majority of brick transformation and upgrading to bring Better efficiency.

　　4 Conclusion

　　In people's minds, sintered brick has a certain position since ancient times, although there are many new types of building materials, but they and the sintered brick function and applicability can not be compared. After deep processing of plastic brick body is very strong, it is a building material is a kind of handicrafts, people should make full use of its artistic value in the construction field to play its potential, both to maintain the structure of the wall and show its decoration nice. T-type porous brick it has a number of properties, and the advantages of brick to the extreme, can not but say that this is a fly. The new multi-function molding machine for small and medium-sized brick-making machinery factory and large-scale brick-making enterprises to upgrade and provide a powerful help.
