    Select principle

    (1) Consider the nature of the type of bonding material size and hardness;

    (2) Considering the shape of the structure and process conditions bonding material;

    (3) Considering the load on glued parts and forms (tension, shear, peel strength, etc.);

    (4) To consider the special requirements of materials such as high temperature and low temperature thermal conductivity.

    Bonding material properties

     

    Metal:The metal oxide film on the surface of the surface-treated, easily glued; the two-phase linear expansion coefficient of adhesive bonding of metal that much difference, layer prone to stress; other metal bonding site is easy due to the action of water generate electrochemical corrosion.

    Rubber:Polar rubber is larger, better bonding effect. Wherein the polar nitrile neoprene, large bonding strength; natural rubber, silicone rubber and butyl rubber small polar bonding strength is weak. Also rubber surface often have liberated release agent or other additives, impede bonding effect.

    Wood:The case of a porous material, easy to absorb moisture, causing dimensional changes may therefore stress concentration. In addition, the rough surface area material good polished wood glued performance.

    Plastic:Plastic polar bonding its good performance.

    Glass:The glass surface from the microscopic point of view is part of the Ministry of numerous irregularities uniform composition using good wettability adhesives to prevent the presence of bubbles may affect the bump at The glass is si-o- as the main structure. , the surface layer of adsorbed water easily. due to strong polarity glass, polar and hydrogen bonding adhesive surface occurs easily form a strong bond. glass easy to rattle and also transparent, adhesive should be considered when selecting these.

    Features and Options

    (1) Connected to a variety of elastic modulus and thickness of different materials, especially thin material;

    (2) Glued surface smoothness, good aerodynamics;

    (3) Good sealing performance, good corrosion;

    (4) To extend the glued pieces of life and reduce the glued parts by weight;

    (5) Low labor intensity, low cost, high production efficiency;

    (6) Non-seismic insulation heat conductive adhesives, in which:

    A, Modified epoxy resin flexibility in the order of:

    Epoxy - polysulfide> Epoxy - Polyamide> Epoxy - amine curing agent;

    B, Modified phenolic flexibility in the order of:

    Phenol - Polyamide> Phenolic - polyvinyl acetate> phenolic - epoxy;

    To ensure the quality of the adhesive points

    In order to ensure the quality of the adhesive, you must do the following:

    (1) Select just its use of adhesives.

    (2) High good balance between adhesive strength and durability aspects.

    (3) Do not use more than the storage and application of the adhesive.

    (4) One-component glue if stratification, sedimentation, should Stir well before use.

    (5) Multi-component adhesive should be required to allocate mixing ratio.

    (6) Do not use a simple docking.

    (7) Maximize the use of lap, miter, sockets, mixed connection.

    (8) The lap length is not too long.

    (9) Do not use the lap adhesive laminates, and miter

    (10) Plus screw plus riveting, crimping corners to prevent peeling.
