A summary of common basic knowledge in the adhesive industry (Ⅶ)

Bonding process (3)

41. Lining plate (caul): When gluing, the upper and lower plates are sandwiched between the assembly parts and put into the press for pressurization.

42. Press: A machine that applies pressure to assembly parts to bond them.

43. Vacuum bag: a soft bag that uses vacuuming to apply pressure to the accessories inside the bag.

44. Autoclave: a heated and pressurized cylindrical device used for curing assembly parts. Glued products and their defects.

45. Assembly for adhesives: Assembly that is stacked together after being glued or has been bonded.

46. Bonded assembly: An assembly that has been bonded.

47. Structural bond: A bonded joint that can withstand allowable stress and environmental effects for a long time.

48. Honeycomb core: Honeycomb material made of skeleton materials such as metal foil, paper or fiberglass cloth and adhesive. Used to manufacture honeycomb sandwich structures, etc.

49. Sandwich structure: A structure formed by bonding a layer of core material (such as honeycomb core, foam plastic, corrugated board, etc.) between two layers of panel materials.

50. Adhesive joint: The part where two adjacent adherends are bonded together with adhesive.

51. Single lap joint: A joint formed by partially overlapping the main surfaces of two adherends and gluing them together.

52. Butt joint: A glued joint in which the two ends to be glued or one end face is perpendicular to the main surface of the adherend.

53. Angle joint: A glued joint in which the main surface ends of two adherends form a certain angle.

54. Scarf joint: Cut two adherends into corresponding sections other than 90°, and glue the two sections together to form a joint with the same plane.

55. Dado joint: Tongue-and-groove glued joint.

56. Dowel joint: A joint in which the bonded parts of two adherends form a pin hole or annular structure (such as rods and pipes, pipes and pipes).

57. Starved joint: The amount of glue is insufficient and a satisfactory gluing effect cannot be obtained. Note: This situation occurs because the glue is too thin to fill the pores between the adherends; the adhesive penetrates into the adherends excessively; the assembly time is too short or the bonding pressure is too high.

58. Laminate: A product made of two or more layers of materials bonded together.

59. Cross laminate (cross laminaate; crosswise laminate): A laminate in which the texture of some layers (or the direction of greatest tensile strength) is oriented in the same direction as the texture of adjacent layers (or the direction of greatest tensile strength) ) are oriented at an angle of 90°.

60. Parallel laminate: A laminate in which the orientation of the texture (or direction of maximum stretch yield) of all layers is approximately parallel.

61. Plywood: A group of veneers usually assembled and glued perpendicularly to each other in the direction of adjacent layers of wood grain. Usually the surface panel and inner layer panels are symmetrically arranged on both sides of the central layer or core.
