Abstract
The invention relates to a method for manufacturing a heat preservation layer of a tank body. The method for manufacturing the heat preservation layer of the tank body solves the problems that in the prior art, after foams are injected and foaming is completed, the center of the top of a polyurea coating will plump up upwards, the uneven and unattractive surface is caused. Meanwhile, through a prefabricated polyurea plate and a polyurea coating, the surface of the tank body is sprayed with foam with a certain thickness, and then working is done; and accordingly foaming of the spayed foam can be completed firstly, a less amount of PU foam is injected into the polyurea coating finally, and the surface of the heat preservation layer will not plump up after foaming, so that the surface of the heat preservation layer is smooth and attractive.
Description
Technical field
The present invention relates to a kind of making method of liquid gas heat insulation tank, this heat insulation tank has better sealing thermal insulation and aesthetic function.
Background technique
LNG/LPG/LEG ship is the specialized ships of transport liquefied gases at low temperatures, in this natural gas carrier vessel of new generation, deposit the storage tank be incubated LNG Liquefied natural gas, on tank surface, spray coating heat preservation structure plays and stores sealing and insulation effect, can prevent fluid seepage.
But when thermal insulation layer making being carried out to the liquid gas heat insulation tank surface on ship in the past, being that polyureas coat is laid at dunnage top by installing dunnage at tank surface at the scene, after the boring of polyureas coat, internally injecting PU foam.But after the frostproof froth n injected like this, the top center of polyureas coat can upwards be heaved, and causes surface irregularity, unsightly.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of making method of tank body thermal insulation layer, this making method is not only convenient and swift, and polyureas coat top center can not be protruding simultaneously, and surfacing is attractive in appearance.
The object of the present invention is achieved like this:
A making method for tank body thermal insulation layer, steps of the method are:
One, prefabricated polyureas plate and polyureas coat;
Two, at tank surface spray foam at least one times, in foam, glass web is covered with;
Three, lay prefabricated polyureas plate at the spaced surface of foam, between the bottom of polyureas plate and foam head, leave gap, by the fixed block inserted in foam, polyureas plate is fixed after polyureas plate head and the tail are bending;
Four, between the bottom and foam head of polyureas plate, spray PU foam, polyureas plate and foam head are fixed, takes out fixed block subsequently;
Five, between the top of adjacent two blocks of polyureas plates, lay prefabricated polyureas coat, the both sides of polyureas coat are fixed on the top of polyureas plate;
Six, on polyureas coat, get through hole, fill foam between polyureas coat and foam, subsequently by the holes blocking of polyureas coat;
Seven, cover Stainless Steel Cloth at the outer seam of adjacent two pieces of polyureas, two pieces of polyureas coats bond by Stainless Steel Cloth surface spraying polyureas.
The number of times of the spray foam in step 2 is twice, first at tank surface spray foam, and on foam cover glass net, then spray foam up, then cover glass net.
In step 2 after spray foam, thickness and the target thickness distance 30-50mm needing to spray of foam.
Polyureas plate in step one is strip, is sprayed with foam bottom polyureas plate.
Polyureas coat in step one, by the online spray polyurea layer of Stainless Steel Wire, makes Stainless Steel Cloth be coated in polyurea layer completely and forms.
The fixed block used in step 3 and step 4 is latch.
Use western stuck glue by the holes blocking of polyureas coat in step 6.
Compared with prior art, the invention has the beneficial effects as follows:
The making method of this tank body thermal insulation layer is by prefabricated polyureas plate and polyureas coat, first after tank surface sprays certain thickness foam, carry out operation again, so just, make the foam of previously spraying to complete foaming, and the PU foam output finally inwardly injected from polyureas coat is few, just insulation layer surface can not be made after foaming to heave, make insulation layer surface smooth, attractive in appearance.
Accompanying drawing explanation
Fig. 1 is the working process schematic diagram of the making method of tank body thermal insulation layer of the present invention.
Wherein: tank body 1, foam 2, polyureas plate 3, latch 4, polyureas coat 5.
Embodiment
See Fig. 1, the present invention relates to a kind of making method of tank body thermal insulation layer, steps of the method are:
One, prefabricated polyureas plate 4 and polyureas coat 5, this polyureas plate 4 is in strip, foam is sprayed with bottom polyureas plate 4, polyureas plate 4 is coated on the outer surface of tank body 1 after can bending from beginning to end, polyureas coat 5, by the online spray polyurea layer of Stainless Steel Wire, makes Stainless Steel Cloth be coated in polyurea layer completely and forms.
Two, at tank body 1 surface spraying foam 2, and on foam 2 cover glass net, then spray foam 2 up, then cover glass net, repeatedly make the integral thickness of foam 2 and the target thickness distance 30-50mm needing to spray after spraying.
Three, lay prefabricated polyureas plate 3 at the spaced surface of foam 2, leave gap between the bottom of polyureas plate 3 and foam 2 top, fixed by polyureas plate 3 by the fixed block inserted in foam 2 after polyureas plate 3 head and the tail are bending, this fixed block can be latch 4.
Four, between the bottom of polyureas plate 3 and foam 2 top, spray PU foam, polyureas plate 3 and foam 2 top are fixed, takes out latch 4 subsequently.
Five, between the top of adjacent two blocks of polyureas plates 3, lay prefabricated polyureas coat 5, the both sides of polyureas coat 5 are fixed on the top of polyureas plate 3.
Six, on polyureas coat 5, get through hole, fill foam between polyureas coat 5 and foam 2, subsequently with the holes blocking of western stuck glue by polyureas coat 5.
Seven, cover Stainless Steel Cloth at the seam crossing of adjacent two pieces of polyureas coats 5, two pieces of polyureas coats 5 bond by Stainless Steel Cloth surface spraying polyureas, thus complete the laying of tank body 1 insulating layer.
