Material selection and structural design standards for stone curtain walls

1、 Stone sealing should be designed according to the external enclosure structure, and the stone curtain wall slabs should be made of igneous rock. 2、 Natural stone curtain walls are not suitable for use in high-rise and super high-rise buildings. When required by the design, measures should be taken to prevent stone fragmentation.

Composition and classification of abrasives for stone processing

Grinding tools are composed of abrasives, binders, fillers, pores, and additives. Basic requirements for abrasives: 1. The hardness is higher than that of the processed material; 2. Has certain toughness, strength, and sharpness handling ability. 3. It should have a certain mechanical strength. 4. Maintain inherent hardness and strength (i.e. red hardness or thermal stability) at high temperatures.

Stone processing methods and processes

Raw materials: irregularly shaped stones directly separated from mines. Raw materials: stone materials processed from raw materials, with certain specifications, used for processing decorative panels. Mao (Guang) board: a board made by sawing mountain waste materials. Mirror finish large board (commonly known as large board): A board with a smooth surface and a mirror like luster after grinding and polishing the rough board. Specification board: A board that conforms to the standard specifications.

What is the difference between marble and granite

Marble refers to a type of carbonate rock that has undergone transformation or accumulation. Its main chemical component is calcium carbonate, accounting for more than 50%, as well as magnesium carbonate, calcium oxide, manganese oxide, and secondary silica. Marble belongs to medium hard stone materials.

Detailed explanation of stone processing knowledge

The surface effects of stone mainly include: smooth surface, matte surface, acid washed surface, sandblasted surface, burnt surface, chopped axe surface, lychee surface, hammered surface, brushed surface, antique surface, mushroom surface, natural fracture surface, and special surface.

Processing technology

Use a crane to load the raw materials onto a waste truck, which is then transported by a shuttle truck to the working position of a frame type sand saw to saw and cut them into rough boards. The boards are then processed into smooth boards through processes such as grinding, polishing, and cutting, and finally inspected, packaged, and stored. The detailed process is as follows: Raw material hoisting → sawing → washing and inspection → rough grinding → fine grinding → fine grinding → polishing → cutting and repairing → inspection and packaging
