    Shandong Shengya Machinery Co., Ltd. specializing in the production of various types of brick, brick machine, brick machine, hollow brick, pavement brick and other equipment of the old brick factory.
          Hollow brick and block brick difference there?
    1. The outer wall thickness of hollow bricks: Under ordinary circumstances, under the conditions of the same porosity holes, porous hollow brick than the big hole, high compressive strength and flexural strength interference holes hollow brick. For example, when a large hole, the hole hole hollow brick outer wall of the load-bearing wall thickness less than 20-25mm significantly decreased its intensity; and porous, hole bearing hollow brick outer wall thickness were 20mm, 15mm, while 12mm, its strength basically the same. To ensure the hollow brick has good mechanical properties, holes, outer wall thickness of the porous hollow brick can be thin; and outer wall large hole, small hole in the hollow brick will have thicker.
    2. The hole direction hollow brick: low 60% to 80% compared with parallel holes in the direction of strength hollow brick vertical intensity to the hole direction (which is bearing hollow brick holes, mostly vertical holes; instead support through hollow brick holes are mostly horizontal hole s reason). So bearing hollow bricks should pay attention to make the hole in the direction perpendicular to the ground.
    3. The hollow brick porosity: When the hollow brick porosity of less than 35%, the compressive strength of the vertical hole hollow brick hollow brick equivalent. When the hole was 35% to 40%, only a slight shadow on the compressive strength noon. Because of increased porosity. The extruded brick pressure increases, so that the inner and outer walls of hollow brick density increases, the compensation due to increased porosity and reduced compression arc. When the hole was 40% to 50%, the strength of the masonry wall post will decline.
    Flexural strength hollow brick generally increases the porosity decreases, but if the thickness of the hollow brick is large. Fight off strength has little effect, but it should pay attention to each other to make the holes staggered.
