Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Detailed description of the invention one: as shown in figures 1 to 6, Fig. 1, Fig. 2 are the schematic cross-sections of two kinds of typical forms of hollow glass heat insulating bar. It is characterized as being transition zone 31,32 and plastic layer 201,202 and metal level 101,102 is wrapped in the inside.
Hollow glass heat insulating bar include plastic layer 201,202, transition zone 31,32, metal level 101,102, it is characterized in that: metal level 101,102 is the U-shaped bar that the upper end of strip has upper bending section 11,16, side 12,17,15,19 and two, the bottom surface in U-shaped bar cross section is plane and is mutually perpendicular to, U-shaped two bottom sides is respectively arranged with a bending deformation relief area, relief area is circular arc A13 outwardly and the circular arc B14 coupling part caved inward or circular arc C 18 part outwardly, for eliminating the expand with heat and contract with cold contraction of generation, stress; Metal level 101,102 increases the strength and stiffness of hollow glass heat insulating bar; Metal level 101,102 carried out solvent oil removal treatment or plasma surface oil removal treatment before coating transition zone 31,32; Transition zone 31,32 is coated in the surfaces externally and internally of metal level 101,102, the caking property of transition zone 31,32 and plastic layer 201,202 and metal level 101,102 is all good, plastic layer 201,202 is coated on the surface of described transition zone 31,32, be positioned at inside and outside its surface and and its conformal, transition zone 31,32 by plastic layer 201,202, metal level 101,102 bonds together, the upper end of 21,25 and two sidewalls 22,26 of upper plane of plastic layer 201,202 connects, and encloses substantially rectangular shape; Length direction extends along rectangular vertical direction, the space segment 51,52 of rectangle is used for storing moisture absorption molecular sieve 7, upper plane 21,25 is provided with multiple moisture absorption aperture 24 along its length, and moisture absorption molecular sieve 7 passes through moisture absorption aperture 24 by the moisture absorption in hollow space 68, it is prevented that frosting, condensation.Metal level 101,102 is likely to have greasy dirt, dust, dirt etc. in surface in rolling, transport, storing process, the adhesion strength causing the surface of metal level 101,102 and transition zone 31,32 will be substantially reduced, solvent oil removal treatment or plasma surface oil removal treatment can effectively solve the problems referred to above, plasma surface oil removal treatment makes that metal level 101,102 surface is crude, surface tension substantially increases, add adhesive force, adhesive strength, shear strength significantly improve, faster, production efficiency is higher for speed of production.
The material of plastic layer 201,202 is ethylene-vinyl alcohol copolymer (EVOH) or polypropylene (PP) or polyethylene (PE) or polyamide (PA) or polyurethane (PU), and thickness is 0.5-1mm. Preferably ethylene-vinyl alcohol copolymer, is the fabulous material of barrier property, and waterproof, gas, protection against the tide, weatherability and excellent in stability are particularly suitable for packaging material, for instance the barrier material such as casing, milk, instant noodles. The molecular sieve moisture absorption is put in the centre of heat insulating strip. Containing calcium chloride in sieve component, calcium chloride can produce corrosive substance after running into water, the metal of corrosion compound parting bead, this is also why metal level 101,102 is wrapped in the inside reason, plastic layer 201,202 will not run into this problem, there is resistance to corrosion, improve the service life of hollow glass heat insulating bar.
Transition zone 31,32 is low-molecular-weight low melting point polypropylene (PP) or the binding agent of polyethylene (PE), and thickness is 0.01-0.1mm.
