Abstract
The insulating layer construction method of the low-temperature storage tank of the present invention, including prepare polyester insulating layer, prepare fiberglass protective layer；Cutting forms dashpot, fills elastic joint filling agent in dashpot on the fiberglass protective layer.The present invention forms buffering area using elastic joint filling agent on fiberglass protective layer; to absorb the modified difference generated due to elasticity modulus, the Poisson when difference of linear expansion coefficient between polyester insulating layer and fiberglass protective layer; efficiently solve low temperature cold insulation field because using fiberglass as mechanical protection layer, and be likely to occur glass fiber reinforced plastic surface deformation, destruction the phenomenon that.
Description
Technical field
The present invention relates to the insulating layer construction methods of the insulating layer of low-temperature storage tank more particularly to a kind of low-temperature storage tank.
Background technology
Existing part Cryo Equipment, prepares one layer of fiberglass protective layer usually outside polyester insulating layer, and fiberglass is protected
Sheath is prepared by hand-made or spraying method.Protective layer, which plays, to be prevented vapor from entering thermal insulation material, prevents from hitting
The effect hit.But due to being applied to Cryo Equipment field, thermal insulation material is prepared in thermal insulation material outer surface by cold events
Fiberglass leads to thermal insulation material shrinkage and expansion deformation due to expanding with heat and contract with cold, to cause deformation to fiberglass protective layer, destroy.
Invention content
The purpose of the present invention is exactly to solve the above-mentioned problems, to provide a kind of insulating layer construction method of low-temperature storage tank.
In order to achieve the above object, the present invention is achieved through the following technical solutions：A kind of insulating layer of low-temperature storage tank is applied
Work method, includes the following steps：
One, one strata ester insulating layer is prepared by the technique of spraying on the surface of low-temperature storage tank；
Two, using cutting machine and sander, cutting polishing is carried out to the polyester insulating layer of spraying, makes polyester insulation layer surface
It is smooth；
Three, it by hand-made or spraying method, prepares one layer of fiberglass in smooth polyester insulation layer surface and protects
Sheath；
Four, it after waiting for that fiberglass is fully cured, is slightly polished glass fiber reinforced plastic surface using sander, abrades uneven surface
The fiberglass in main plot domain, and the region of existing defects is repaired；
Five, in fiberglass protective layer, dashpot cutting track is marked using marking pen；
Six, fiberglass protective layer is cut along cutting track using trimmer, removes the glass within the scope of cutting track
Glass steel forms dashpot；
Seven, in one layer of thin adhesive tape of each stickup at the 1cm of dashpot both sides；
Eight, using elastic joint filling agent fill tool, elastic joint filling agent is filled between two thin adhesive tapes, makes to fill out in dashpot
Full elastic joint filling agent, forms buffering area, is used in combination the tools such as scraper plate to apply surface and is scraped；
Nine, tearing-off adhesive tape after the completion of scraping is applied, the insulating layer construction of low-temperature storage tank is completed.
The thickness of the polyester insulating layer is 100-400mm.
The thickness of the fiberglass protective layer is 2-3mm.
The width of the buffering area is 5-8mm.
The quantity of dashpot is set according to the size of low-temperature storage tank, it is a plurality of along being axially and radially respectively set for low-temperature storage tank
Dashpot, the spacing between adjacent buffer slot are 80cm-100cm.
The elastic joint filling agent is： MS 930TM。
The present invention forms buffering area using elastic joint filling agent on fiberglass protective layer, to absorb polyester insulating layer and glass
The modified difference generated due to elasticity modulus, the Poisson when difference of linear expansion coefficient between steel protective layer, efficiently solves low
Warm cold insulation field because using fiberglass as mechanical protection layer, and be likely to occur glass fiber reinforced plastic surface deformation, destruction the phenomenon that.
Specific implementation mode
