[0002] Silicate is made of hard clay clinker as raw material, produced by resistance or arc furnace melting and blowing fiber forming process. Because of its low thermal conductivity, excellent thermal stability and chemical stability, it is often used to make high temperature resistant fireproof sound insulation cotton, boards, tubes, inorganic fireproof decorative panels and inorganic fireproof roller shutters.

[0003] At present, when storing silicate insulation boards, in order to save space, the materials of the silicate insulation boards are usually stacked very high. When the stacking height of the silicate insulation boards exceeds 2 meters, workers are required to stack the silicate insulation boards through a platform ladder.

Therefore, further improvement is needed. Utility Model Content
