Use Mianshaozhuanji equipment can be said to us into an era of mechanized brick, which is an important sign of the times. In particular, this brick-making process, compared to traditional brick process easier, the entire production process, eliminating the step of traditional firing at full mechanization of production, we only need to table a reasonable operation and control, it is possible to produce a very high number of unburned.

 However, the production of cement brick hollow blocks, often produces extrusion molding defects, defect causes a variety of reasons for each defect varies, to analyze its causes and try to defense.

1 mud rotten corner

Sophisticated mud cracks appear corners, cracks turned backward. The main reason is the middle of the mud extrusion speed, one can head to the middle of the core with the extended core, or in the middle of the head behind the mandrel core set period of resistance mud tubes to reduce the amount of mud into the middle; Second increase the feed end of the four corners of the mouth machine arc, to expand into the mud around.

2 mud rotten heart

Clay center blossom, rolled to four weeks, squeeze machine mud obvious bulge in the middle. Mainly in the middle of mud extrusion machine speed. One can put in the middle of the core head with elongated core, or in the middle of the head behind the mandrel core set period of resistance mud tubes to reduce the amount of mud into the middle; second is to increase the feed end of the four corners of the mouth machine curvature to expand into the mud around.

3 clay bend

First, the mud when the machine outlet is bent to one side, while thick brick wall, while thin. The main reason is machine interface, core tools, clay cylinder and spiral reamer not on the same center, should be corrected. Second, the mud zigzag forward, pulled sunken bad place sometimes. The main reason is crowded brick machine spiral reamer main leaf and top deputy leaves missing, or vice leaf badly worn, respond spiral reamer main lobe and vice leaves for repair or replacement.

4 clay deformation

Mainly because of insufficient strength clay, forming the water is too high, the water is adjusted to deal with molding.

5 laterally off mud cracks

Transverse rupture caused mud two main reasons. First, forming water is too low, adjust the water to deal with molding; Second, low plasticity index of raw materials, processing of raw materials should be strengthened, such as reducing the particle size of the raw material crushing, aging time increases of raw materials, such as refining the raw material to grind improve the plasticity index of raw materials.

6 clay jagged crack

Produce jagged cracks are mainly caused by the following reasons. First, the machine side of the corner of the mouth or the second layer of water on both sides of the gap is too big, too much lubrication water, produced water small teeth crack; Second machine last two dry mouth, excessive water in front of a layer again, water is generated big teeth crack; three is just around the corner machine a second layer of dry mouth, producing anhydrous small teeth crack; four layers of all the water is around the corner, it will produce anhydrous big teeth crack; Fourth corner all of the layers of water, it will produce anhydrous large tooth cracks. Should be based on the specific circumstances, according to the corresponding position adjustment waterways.

7 mud hole deformation

First, narrow hole, core head wear may be serious or indentation machine mouth too much, should be replaced or adjusted. Second, the shift hole, core rod may be skewed or too thin, you should align the core rod or replacement. Third, the middle hole individual flowering, to the surrounding pulls. The reason is that the bulk of the plane of the core head is outside the mouth of the mud flat side of the machine, the application of the nut head pressed into the core point. Fourth hole collapse deformation, because mud is too soft, you should adjust the molding moisture.

8 mud holes occur within the scale crack

The first cracks appeared in almost all the holes, the main reason is the core head surface roughness or poorly designed, taper inappropriate, surrounded resistance serious imbalance, or mud is too dry, too hard cause. Second, only the individual holes appear, the only problem with this core head should be polished smooth or modify the core head design.

9 Two top surface clay longitudinal cracks

Two top surface of the mud caused by longitudinal cracks (core frame cracks) mainly due to a combination of adverse secondary mud. In order to ensure a good combination of secondary mud, strong frame to prevent core lines, should make a large blade end of the core to the machine with the mouth of the exit plane has a reasonable length, the "healing length." Random mouth healing length should increase net amount of mud and lengthened, plasticity index difference between the materials the healing length should be longer.

10. clay middle recessed

Extruded clay obviously intermediate recess. Mainly middle mud caused by slow squeeze machine. May be appropriate to put in the middle of the core head with a shortened core, or reduce the resistance of the central cone of mud into the mud to increase the amount of the central region.
