Description
Technical field
The present invention relates to a kind of insulation board and its production and installation methods.
Background technique
Insulation board seam crossing connection type is frequently with PVC structure, plug in construction, press strip link structure, eccentric hook structure
Etc. connection types, these structure seam crossings be all by smear silicone sealant be sealed, inevitably will appear after a long time
Leakage, phenomena such as sealant is mouldy, make the heat insulation effect of insulation board be deteriorated, and growth bacterium influences the quality of quick frozen product.
Insulation board seam crossing leakage, causes cooling capacity in library to leak, and storehouse temperature increases, and the freeze-off time of frozen product is elongated, makes
The production capacity of equipment reduces, if the production capacity to be remained unchanged, it is necessary to increase energy consumption, improve cost.If seam crossing has water infiltration
Thoroughly into the foamed heat insulating sandwich layer of insulation board, the heat insulation effect of insulation board can be equally reduced.If the silicone of insulation board seam crossing
Sealant is mouldy to breed bacterium, so that quick freezing unit is freezed out the product bacterium come exceeded.The insulation board originally used it is inside and outside
Packaging material is foamed heat insulating sandwich layer, generally 0.6mm or 0.7mm, these structures are since gap is larger and plate is relatively thin and nothing
Method is fully welded.
The welded type connection now used, in order to reduce welding deformation, the inside and outside packaging material of insulation board is changed to 1.5mm, increases
In addition nonrecurring cost can make foamed heat insulating sandwich layer burn, and can make the inside and outside packet of insulation board using the high temperature that welding generates
Remove foamed heat insulating sandwich layer.
