Dry hanging stone curtain wall construction stone selection requirements

Dry hanging stone curtain wall construction stone selection requirements

Firstly, the color of the stone is selected and classified by colorimetry; the color of the stone installed on the same side should be the same, and according to the design size and drawing requirements, the special mold is fixed on the bench drill for stone drilling. In order to ensure the position is accurate and vertical, a slate bracket should be nailed so that the slate is placed on the bracket. The small surface to be perforated is perpendicular to the drill bit, so that the hole is formed accurately, the hole depth is 20mm, the hole diameter is 5mm, and the drill bit is 4.5mm.

Then the unsaturated resin glue is brushed on the back of the stone, mainly using a cloth and two glue. The cloth is a non-alkali, flawless 24 mesh glass cloth. Before the brush head is glued, the number is written on the stone board and the stone board is placed. The floating ash and impurities on the top are cleaned, such as rust and iron foam. Use a wire brush or coarse sandpaper to remove it and then brush it over the glue. The glue should be used as needed to prevent waste after curing. It is necessary to pay attention to the corners. It is necessary to brush the corners. In particular, the punched area is a weak area. It must be brushed, the cloth should be covered, and the glue should be finished. When laying the fiberglass mesh, use it from side to side. Brush the brush, level the brush and then brush the glue twice. Do not use too much glue to prevent the flow to the stone face, which will bring difficulties to the caulking and quality problems.

The above contents are compiled according to the problems encountered by the students in the actual work, for reference, if there is any problem, please communicate and correct in time.

HHCMS-200 carbon molecular sieves
CMS-200 is a new kind of non-polar adsorbent specially designed for extracting nitrogen-rich gas from air. It is suitable for separating nitrogen from air. It has a high adsorption capacity for oxygen and can separate nitrogen from air.
The most notable feature of the Carbon Molecular Sieve is its high gas-producing efficiency, especially the preparation of nitrogen with a purity of less than 99.5%.

It is widely used in large air nitrogen making equipment.

Project parameters

The diameter of:1.0-1.3   1.3-1.5

Packing density:≥660kg/m³

The intensity of particle:≥95

Compressive strength abrasion:≤1%

The moisture content:≤0.5%

Standard packing:20Kg/barrel. 40Kg/barrel. 130Kg/barrel

The adsorption time of test condition was 58s with an average pressure of 1-2s

Pay attention to
1. The nitrogen production equipment can reduce the adsorption temperature to better show its excellent nitrogen production performance under conditions;
2. Pay attention to low temperature drying and seal preservation during storage;
