Secondly, a layer of varnish should be painted on the packaging box to avoid film remover, rainbow line and small diameter flat mouth. The film removal time must depend on the seasonal thickness. The thickness of ordinary plates is mostly between 4-20 mm, and the selection also depends on the aperture. Too much is not intuitive.
● Before purchasing containers, it is recommended that you still choose the container plate. Novel style is the key, and the quality of the container.
In order to ensure the solidity of the packaging box, more and more manufacturers will choose the e0 grade pur rubber seal box edge band, pur rubber seal.
EPS has good heat preservation and energy saving effect, "micropore" is common, the dosage is 20~30kg, and the foam board with a thickness of 40mm should be made.
● The polyurethane cold storage board uses light polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that the thermal insulation performance is very good. The exterior of the polyurethane cold storage board is made of SII, PVC color steel plate and stainless steel plate components. The advantage of this is to prevent the cold storage board from spreading temperature due to the large temperature difference between the inside and outside, thus making the cold storage more energy efficient and improving the working efficiency of the cold storage.
Due to the excellent thermal insulation performance of polyurethane sheet, under the same thermal insulation requirements, it can reduce the thickness of the building envelope, thus increasing the indoor use area.
Polyurethane composite plate has light weight, beautiful appearance and good corrosion resistance, and can be directly processed and used. It provides a powerful decorative building material for the construction industry, marine industry, etc., and promotes energy conservation and environmental protection in China. The polyurethane continuous polyurethane composite plate is compounded once from the external wall of the factory to the beam and plate. The panel and door panel have excellent pressure and impact resistance, which is conducive to the protection of buildings.
Polyurethane color steel foamed composite board is used for the integrated house of steel structure workshop and various structures. Its main roof material is polyurethane rigid foam plastic. Steel plate is used for internal insulation of internal and external walls of buildings.
