Block the production of national standards
For hollow bricks, everyone knows that it has many advantages, such as clay shale hollow bricks is, as the main raw material, through raw material treatment, forming and sintering. Hollow bricks advantage is qualitative light, intensity tall, insulation, sound insulation good noise performance. So hollow bricks to meet production standard but few people know, below we zhengzhou hollow brick machine to introduce the hollow bricks and hollow blocks in the process of production to meet national standards:
Second, hollow blocks class (the mechanical molding production process, hollow blocks single class production capacity of not less than 50000 cubic meters per year, the autoclaved aerated concrete block production capacity of not less than 100000 cubic meters/year)
1. Ordinary concrete small hollow blocks (meet the technical requirements of the GB8239-1997).
2. Lightweight aggregate concrete small hollow blocks (accord with national GB/T15229-2002 technical requirement).
3. Sintering hollow blocks (in coal gangue, construction waste, shale as raw material, accord with GB13545-2003 technical requirements).
4. The autoclaved aerated concrete block (accord with GB/T11968-2006 technical requirement).
5. Gesso block (accord with JC/T698-1998 technical requirement).
6. Fly ash small hollow blocks (meet the technical requirements of the JC862-2000).
