InactiveCN101973693AGood supportImprove yield and mechanical strengthGlass reforming apparatusGlass productionEngineeringSurface plate
The invention discloses a method for preparing an isolated supporting point array between front and rear vacuum glass substrates by using screen printing equipment. The method comprises the following steps of: preparing low-melting glass powder into screen printing size, printing on the front glass substrate by using screen printing, and preparing the isolated supporting point array between vacuum glass panels by drying, sintering and other processes, wherein the diameter of each cylindrical point is 0.1 to 1.0mm; the thickness is 20 to 250 mu m; and longitudinal and transverse spacing between the points is 20 to 100mm. A sealing layer for sealing the edges of the vacuum glass is prepared on the rear glass substrate; the softening temperature of the used low-melting glass powder is 3 to 30 DEG C lower than that of the low-melting glass powder for preparing the supporting point array; and the thickness of the isolated supporting point is 1 to 20 mu m higher than that of the sealing layer on the edges of the vacuum glass. Under the action of the sealing temperature of the sealing layer on the edges of the vacuum glass and clamp pressure, the deformation of a supporting point sintered body is slightly lower than that of a sintered body on the edges of the sealing layer, and each supporting point in the supporting point array can be contacted with the front and rear glass substrates and is uniformly stressed on the premise of realizing edge airtight seal on the edges.

Solid gel cushion

Disclosed is a solid gel cushion. The solid gel cushion includes at least one first elastic quadrilateral body with four elastic side walls, wherein the bottom surface and the top surface of each first elastic quadrilateral body are open. A second elastic quadrilateral body with four elastic side walls is connected to the four elastic side walls of each first elastic quadrilateral body. Two elastic supporting ribs staggered in a crossed way are formed in the second elastic quadrilateral body. The bottom surface of the second elastic quadrilateral body is a closed surface and the top surface of the second elastic quadrilateral body is open, which allows each first elastic quadrilateral body to be surrounded by four second elastic quadrilateral bodies. When a user sits or lies or leans on the top surface of the solid gel cushion, the top surface of each second elastic quadrilateral body is sealed by the user's body. The air in each second quadrilateral body is compressed to allow the pressure to become high and the volume to expand, which results in that the four side walls of each second elastic quadrilateral body expand to the inner space of each first elastic quadrilateral body, thereby realizing support effect. The inner space of each first elastic quadrilateral body is reduced and the air is discharged through a hollow channel of the space of each first elastic quadrilateral body, thereby realizing heat dissipation effect.
