[0058] A method for preparing 3D printed air-permeable bricks, the specific operation steps are as follows:
[0059] (1) Material preparation:
[0060] Take the raw materials used in dispersion 1 and weigh them in proportion and mix them evenly;
[0061] The components of Dispersion 1 include alumina powder 68~85%, magnesium oxide powder 4~8%, aluminum powder 5~10%, magnesium aluminum spinel powder 4~12%, additives 1~3% , The binder resin is added with 2~3%; wherein, the additive is: any one or a mixture of one or more of nano-aluminum-rich spinel, titanium oxide powder, and chromium oxide powder; the binder resin is a phenolic resin.
[0062] (2) Preparation of Dispersion Body 1:
[0063] Add the mixture of the dispersion 1 raw material prepared in the previous step to the 3D ceramic printer, using SLS (selective laser sintering) technology, through "printing a layer of mixture → laser scanning resin curing → printing another layer of mixture → laser The process of "scanning resin cu...
Embodiment 2
[0091] The specific operation steps of Embodiment 2 are as follows:
[0092] Take raw material 70% alumina powder, 8% magnesium oxide powder, 10% aluminum powder, 10% magnesium-aluminum spinel powder, 2% mixture of nano-aluminum-rich spinel and titanium oxide powder, plus 2% phenolic resin. Proportionally weigh and mix uniformly, add the prepared dispersion 1 mixture to the 3D ceramic printer, adopt SLS (selective laser sintering) technology, and sequentially go through "printing a layer of mixture → laser scanning resin curing → printing another layer The process of "mixture→laser scanning resin curing" prints out each dispersion 1 layer by layer;
[0093] Welding and assembling the steel shell B7, the down-line plate 8, the cover plate 9 and the steel shell A2 outside the dispersion body 1, the steel shell A2 outside the steel shell A2, and the anchors 5 to prepare a steel structure;
[0094] Put the prepared dispersions 1 into the steel shell A2 of the steel structure in step, an...
Embodiment 3
[0095] The specific operation steps of Embodiment 3 are as follows:
[0096] Take raw material alumina powder 85%, magnesia powder 4%, aluminum powder 5%, magnesium aluminum spinel powder 4%, nano-aluminum-rich spinel 2%, plus 2% phenolic resin, weigh in proportion and mix well. Add the prepared dispersion 1 mixture to the 3D ceramic printer, adopt SLS (selective laser sintering) technology, and sequentially go through “printing a layer of mixture → laser scanning resin curing → printing another layer of mixture → laser scanning resin curing "The process of printing out each dispersion 1 layer by layer;
[0097] Welding and assembling the steel shell B7, the down-line plate 8, the cover plate 9 and the steel shell A2 outside the dispersion body 1, the steel shell A2 outside the steel shell A2, and the anchors 5 to prepare a steel structure;
[0098] Put the prepared dispersions 1 into the steel shell A2 of the steel structure in step, and fasten them with fasteners 3; then place the...
