Problems solved by technology

However, the common disadvantages of these structures are: 1. Plastering is required after the wall is formed; 2. Shrinkage after the wall is formed; 3. The efficiency of the wall is low (small blocks); 4. The usable area is reduced after the wall is formed (blocks thick); 5. The hollow rate is small; 6. The energy saving effect is poor after the wall is formed
[0007] Judging from the situation of gypsum block products at home and abroad and patent retrieval, there is no phosphogypsum, double-row holes, polystyrene board cladding, and high-strength 10 / Pan gypsum blocks produced by the all-dry process

Embodiment 1

[0029] Embodiment 1: As shown in Figure 1, a phosphogypsum block with double rows of holes is obtained by using phosphogypsum as the basic raw material through high-pressure molding, and its main body includes a main wall 1, ribs 2 and ribs 3; Two layers arranged in parallel are connected by four ribs 2 , and the ribs 3 are higher than the main wall 1 to form double ribs; the bottom of the ribs 2 is provided with a groove 4 matching the ribs 3 .

Embodiment 2

[0030] Embodiment 2: The difference from Embodiment 1 is that the rib 3 is also provided with a semicircular hole 5 .

Embodiment 3

[0031] Embodiment 3: On the basis of Embodiment 1 and / or Embodiment 2, a hard polystyrene board 6 partition connected to the ribs 2 is further provided between the parallel main walls 1 .

[0032] The full-dry production method of the phosphogypsum double-row hole block comprises the following steps:

[0033] 1) Raw material treatment: use the dry calcination method (180°C-500°C, staged treatment) to discard the attached water, so that the crystal water content is less than 15%; at the same time, remove phosphorus, acid and other harmful substances in the discarded phosphogypsum , the fluorine content is ≤0.3mg / L, which meets the requirement that the fluorine content of environmental protection building materials is ≤1, and the radioactivity ratio is 0.25.

[0034] 2) Add 15-25% water-soluble glue to the hemihydrate phosphogypsum (the water-sol is made by combining sodium silicate with water, the content of sodium silicate is 12-25%, and the pH is 7); Mix the gypsum evenly; ...

Abstract

The invention discloses a phosphogypsum double-row bore building blocks and the optimum drying producing method. It adopts phosphogypsum as raw material, and taking high pressure molding. The main body includes main wall, rib and protruding rib. The flute matched to protruding rib is set at the bottom of rib. And semicircle orifice is set on the protruding rib. Hard polystyrene clapboard is set between the main paralleled walls. The product has the advantages of high intension, high hollow ratio, good energy saving effect, rapid construction, light weight, and non-shrinking. It decreases drying processes, energy consumption of device and the cost of producing.

Description

technical field [0001] The invention relates to a block production technology for building houses, in particular to a phosphogypsum double-row hole energy-saving block and a full dry production method thereof, belonging to the technical field of building materials. Background technique [0002] In the prior art, the wall materials for construction mainly include: dry coal bricks, sintered ordinary bricks, aerated brick blocks, ordinary chemical gypsum blocks, light aggregate hollow blocks, aerated concrete blocks, pearl shale hollow Blocks and cement hollow blocks, etc. In order to facilitate construction and achieve the purpose of heat preservation, sound insulation, energy saving and efficiency enhancement, hollow blocks of various structures have emerged as the times require. Such as the "light building hollow block" disclosed in Chinese patent 92207867.X, the "wall block" disclosed in 00215490.0, etc., the former adopts three layers of walls and vertical sections to for...
