What's the shock proof in the TV box?
It is a kind of shockproof packaging technology that fills the foamed material with the inside and outside packing box as the standard. This method is very simple, the main equipments include containing isocyanate and polyol resin container and spray gun, when using the first container of two materials in the temperature and pressure required to adjust, then two kinds of material mixed with a single pipeline to spray out of the spray head. From the compound at 10s after the start of foaming expansion, no time can be expanded to 100~140 foam 40s times their original volume, foam formation for polyurethane, after a minute, a rigid and semi rigid foam. These foams will wrap up in any shape. Specific procedures for foaming:A. spray the compound into the bottom of the outer package with a spray gun, until it is expanded and expanded into bread;B. rapidly covers a layer of 2m polyethylene film on the foamed foam;C. puts the items to be wrapped in foam to form a nest;D. quickly covered a layer of 2m polyethylene film on the article;E. then continue to spray into polyurethane compounds for foaming;F. outer packing lid seal.
The model is used to make polystyrene resin and other materials into shape boxes with the same shape as the products, so as to wrap up the shockproof effect of the products. This method is mostly used for packing small and light products.
A series of sheets are used to wrap each piece of inner packing into the outer packing box. This method is mostly used for shockproof packaging of small articles.
And the compression packing method is basically the same, the difference is that the elastic material for small liner, these materials can be displacement and flow, it can effectively direct full force part of the gap, the impact force of the scattered contents.
The use of elastic material to fill or strengthen fragile items, so that it can absorb the vibration or impact of the energy, and guide it to the highest strength of the part of the interior. The elastic material is generally filamentous, thin and granular, so that the products with complicated shapes can be well packed, and the energy can be absorbed effectively when the shock is taken, the external force is dispersed, and the inner articles are effectively protected.
