The structural adhesive used for the hidden frame glass curtain wall must be compatible with the materials that are bonded and contacted with the weatherproof adhesive; the structural adhesive must be stored within the shelf life.

The glass used in the hidden glass curtain wall must comply with the design requirements and the quality should conform to the current national standards. Coated glass coating, its adhesion and life must be reliable, the coating must be installed indoors. The use of other special glass can not be misdirected.

The metal parts used in the hidden frame glass curtain wall, in which the fasteners in contact with the aluminum alloy components must be stainless steel parts, the rest shall be treated with rust prevention, and the parts connected with bolts and self-tapping screws shall be added with organic heat-resistant and wear-resistant pads. sheet. Anti-corrosion measures should be taken between different materials of metal materials.

The types, grades, specifications, colors, and chemical and physical properties of the sealing strips, strips, fireproof and heat-insulating materials and closed-end metal plates used in the hidden frame glass curtain wall must meet the design requirements and the provisions of the current national standards.

If there are test requirements for wind performance, impact resistance, air permeability and rain non-leakage performance, the test experiment must use full-scale simulation of the actual dimensions, and the model experiment must not be reduced. Its test data must meet the design requirements.

The connection between the hidden glass wall and the structure is fixed, and the method of embedding the iron must be adopted. The specification, model, and size of the material processed by the embedded part must be complied with the design requirements.

The connection of the components must be firm and the connection seams of the components must be reliably sealed.

Hidden frame glass wall structure must fill the cavity, bond firmly, and the plastic seam smooth, smooth, no air bubbles. Before the glue seam is cured, effective measures must be taken to prevent the deformation from moving freely. There must be no plastic stains other than glue seams.

Inspection methods: observation, hand touch inspection.

2. Basic items

The surface quality of the hidden frame glass curtain wall shall meet the following requirements:

skeleton

Qualified: The oxide film or coating of the exposed part of the skeleton profile has basically the same color, no pressure deformation, clean surface, no burr, oil spots or other dirt, tight seams.

Excellent: The color of the skeleton profile is the same, no pressure deformation occurs, the surface is clean, no pollution, the splicing is smooth, and the interface is smooth.

glass

Qualified: smooth surface, no warpage, no cracks, no scratches, no external image distortion, line circle.

Excellent: smooth surface, no warping, no cracks, no scratches, uniform color, reflecting the external image without distortion, lines crossed, straight and anastomosis, the appearance of crystal clear and beautiful.

Weatherproof glue seam

Qualified: The width and width of the horizontal and vertical slits are uniform and there is no obvious misalignment. The weather resistant adhesive is firmly bonded to glass and aluminum and the surface of the seam is flat. The glass surface is clean and free of dirt.

Excellent: The size and width of the horizontal and vertical joints are the same, and there is no misalignment. Weather-resistant adhesive is firmly bonded to glass and aluminum, and the surface of the seam is smooth, smooth and consistent in depth and depth. The surface of the glass is clean.

Inspection methods: observation, ruler check.

Hejian Deris Both manufacturer and distributor, specialize on Matrix Body PDC Bit and steel body PDC Bit , Concave PDC Bit. Used for Water well, Geology , oil, natural gas ,ore drilling engineering ,piling and trenchless , product marketing the country and 20 countries and regions in the world. Factory sell directly competitive price .

PDC means Polycrystalline Diamond Composite or Compact. PDC are normally made by sintering many micro-size single diamond crystals at high temperature and high pressure. PDC has good fracture toughness and good thermal stability, and is used in making geological drill bits.
PDC has the advantages of diamond`s high wear resistance with carbide`s good toughness

Proper Application of PDC bit

1. When designing the PDC bit hydraulic parameters, the pump pressure must be greater than 13.0 MPa, using equal or approximate diameter.

2. Due to the poor impact resistance of diamond, the upper and lower drilling rigs cannot touch hard objects, and there must be no falling objects in the well. It is strictly forbidden to drill and dig.

3. It is strictly forbidden to press down when the drill is blocked. Should be connected the Square Drill Pipe to open the pump stroke, but it should not exceed 30 meters Large section ream .

When drilling down to the last two single roots, the joint drill pipe is flushed to the bottom of the well and the circulation is large, and the bottom of the well is circulated clean. Then use a small drill pressure, low speed drilling 0.5 meters, the bottom hole shape.

4. Normal drilling is the preferred drilling parameter. The drilling pressure is 30~60KN and the speed is 217~117 r/min. For every 250~300 meters, a halfway trip must be made.

5. It is not allowed to use PDC bit in the gravel layer and soft and hard staggered formations, and drill when there is falling object at the bottom of the well.

6. It`s good effect in large sections of homogeneous soft to medium hard formations .
