Description
Technical field
The present invention relates to one to cover and mould plate method for demoulding.
Background technology
In order to ensure that the surface of sheet metal or other sheet material does not produce cut etc. in transportation, usually can cover last layer plastic foil on the surface of sheet material, this plastic foil bonding agent is bonded in plate surface.During use, often need plastic foil to remove.Have two kinds of modes at present, a kind of is the mode of tearing with hand, is torn by plastic foil.Another kind is the mode adopting banana oil to soak.Banana oil steam and air form explosive mixture and meet naked light height heat energy and cause combustion explosion.Kickback can be there is with oxidant.Its steam is heavier than air, can be diffused into place quite far away in lower, runs into open flame source and causes and strile-back.If it is large to run into pressure in high temperature body, there are cracking and explosion danger.Banana oil is to eye, and nose, larynx is irritant, oral rear lip, throat burn feeling, occurs dry afterwards, vomiting, stupor etc.Long-term high concentration contacts these product and occurs dizzy, burning sensation, pharyngitis, and bronchitis is weak, emotional etc.; The prolonged and repeated contact of skin can cause dermatitis.That is, the use of banana oil is not only dangerous, and cost is high.Therefore a kind of method developing better removal overlay film becomes current problem in urgent need to solve.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides that a kind of security is better, plate method for demoulding is moulded in low, easy to use the covering of cost.
To achieve these goals, technical scheme of the present invention is as follows: one is covered and moulded plate method for demoulding, it is characterized in that: complete in accordance with the following steps:
(1) sheet material vanning, the case that comes unstuck comprises casing (1) and sealed platform cover (2), described sealed platform cover (2) or casing (1) are provided with degumming agent filler pipe, this degumming agent filler pipe arranges degumming agent fill valve (3), described casing (1) or sealed platform cover (2) are provided with blast pipe, described blast pipe is arranged air bleeding valve (4), in described casing (1), be placed with some separation nets (5) arranged by transverse bar and longitudinal rod longitude and latitude;
The sheet material of band plastic foil is placed in casing (1), often puts layer of plate and just place a separation net (5), then sealed platform cover (2) is covered, casing (1) is sealed;
(2), by degumming agent fill valve (3) filling degumming agent in casing (1), described degumming agent is mixed by carrene and diesel oil, the weight ratio of described carrene and diesel oil is 10:0.5-2, closes degumming agent fill valve (3);
(3), leave standstill 1-2h, then open air bleeding valve (4), get rid of all Volatile Gas in casing (1), then open sealed platform cover (2), take out sheet material, now plastic foil and sheet material depart from.
In such scheme, the weight ratio of described degumming agent carrene and diesel oil is 10:0.8-1.2.Degumming effect is better
Also by sealing ring (6) sealing between described casing (1) and sealed platform cover (2).
Be colourless transparent liquid without carrene in the present invention, have aromatic odor.Be slightly soluble in water, be dissolved in ethanol and ether.Be non-combustible low boiling point solvent, security performance is better, although carrene also has toxicity, we adopt encapsulation process, less to the health hazard of operating personnel.Carrene boiling point is 39.8 DEG C, highly volatile.
Diesel oil is hydrocarbon mixture material, volatilizees together with carrene, and the Volatile Gas synergy of generation, can play good solute effect to the bonding agent of the plastic foil that metallic plate covers.
Place metallic plate coming unstuck in box body, separate with separation net between upper/lower layer metallic plate, the Volatile Gas allowing degumming agent produce like this can penetrate on the separation net of every layer.Degumming agent does not need submergence sheet material, and consumption is few, and security is better, and cost is low.
In such scheme: described sealed platform cover (2) is provided with two degumming agent filler pipes, each degumming agent filler pipe all arranges degumming agent fill valve (3).
In such scheme: three channel-section steels (7) are welded in the bottom surface of described casing (1), described channel-section steel (7) extends along the width of casing (1).This channel-section steel is as the feet of casing.
In such scheme: described blast pipe is arranged on casing (1).
Beneficial effect: raw material of the present invention, security performance are good, efficiency of coming unstuck is high, cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the case that comes unstuck of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment 1, as shown in Figure 1: of the present invention covering is moulded the plate case that comes unstuck and be made up of parts such as casing 1, sealed platform cover 2, air bleeding valve 4, separation net 5, sealing ring 6, channel-section steels 7.
