Manufacturing method of large-aperture honeycomb building block

Abstract

The invention relates to a manufacturing method of a large-aperture honeycomb building block, and belongs to the technical field of artificial stone in chemistry. The manufacturing method of the building block comprises the following steps that (1) materials are prepared; (2) the raw materials are fed into a planetary stirring machine to be stirred for 5 to 7 minutes; (3) the raw materials subjected to material mixing are injected into a mold die cavity defined by left and right die molds; (4) the pressure is applied to mixed materials in the mold die cavity by a hydraulic machine at the hydraulic pressure of 150 to 250kg / cm<2>, so that the raw materials in the mold die cavity are pressurized and compactly formed; and then, the left and right die molds are fixed into a whole; and (5) the left and right die molds fixed into a whole and the building block formed after pressure application are put into a constant temperature and constant humidity box for maintenance under the maintenance conditions of the humidity being 90 to 100 percent and the temperature being 20+ / -2 DEG C; the mold is removed after the maintenance is performed for 8 hours; after the demolding, the building block is continuously maintained in the maintenance box; and the finished product is obtained after the set period is reached. The manufacturing method of the building block has the advantage that polystyrene particles and sludge generated by domestic sewage plants can be used for manufacturing the light-weight building block without secondary pollution.

Description

technical field [0001] The invention relates to a method for manufacturing a large-aperture honeycomb block, which belongs to the technical field of artificial stone in chemistry. Background technique [0002] At present, the treatment of a large amount of domestic sewage in urban filling - the sludge with a water content of 60-85% (including crystal water) after the sedimentation sludge is pressed, filtered and pre-dehydrated is strictly prohibited by local governments because it contains harmful substances such as heavy metals. On-site landfill, although chemically dehydrated and then burned in a furnace or disposed of by a cement factory, the amount of digestion is far from meeting the amount of production. [0003] Most of the 80% water in sludge from domestic sewage plants is crystalline water that is difficult to evaporate even when exposed to sunlight. In order to reduce the water content of domestic sewage plant sludge (even if the water content is reduced to 80% to...

[0004] At the same time, as far as the applicant knows, the wide use of polystyrene products has brought a lot of convenience to people, but because waste polystyrene is difficult to compress and degrade, and people lack sufficient awareness of environmental pollution caused by waste foam plastics, The used waste foam plastic products are discarded at will, and polystyrene has the characteristics of aging resistance, refractory degradation, and corrosion resistance, which has caused serious harm to the environment and has become a major problem in garbage disposal
