Abstract
The invention discloses a plastic sheet degumming agent which is characterized by being formed by mixing dichloromethane and diesel oil, wherein the weight ratio of the dichloromethane to diesel oil is 10 to 0.5-2. Preferably, the weight ratio of the dichloromethane to diesel oil is 10 to 0.8-1.2, and the degumming effect is better. The plastic sheet degumming agent is good in safety performance of raw materials, high in degumming efficiency and low in cost.
Description
Technical field
The present invention relates to one to cover and mould plate degumming agent.
Background technology
In order to ensure that the surface of the sheet materials such as sheet metal does not produce cut etc. in transportation, usually can cover last layer plastic film on the surface of sheet metal, this plastic film caking agent is bonded in plate surface.During use, often need plastic film to remove.Have two kinds of modes at present, a kind of is the mode of tearing with hand, is torn by plastic film.Another kind is the mode adopting lacquer thinner to soak.Lacquer thinner steam and air form explosive mixture and meet naked light height heat energy and cause combustion explosion.Kickback can be there is with oxygenant.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 high temperature body internal pressure, there are cracking and explosion hazard.Lacquer thinner is to eye, and nose, larynx is irritant, oral rear lip, throat burning sensation, occurs dry afterwards, vomiting, stupor etc.Long-term high density 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 lacquer thinner 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 degumming agent 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 degumming agent, it is characterized in that: mixed by methylene dichloride and diesel oil, and the weight ratio of described methylene dichloride and diesel oil is 10:0.5-2.
In such scheme, the weight ratio of described methylene dichloride and diesel oil is 10:0.8-1.2.Degumming effect is better.
Be colourless transparent liquid without methylene dichloride in the present invention, have aromatic odour.Be slightly soluble in water, be dissolved in ethanol and ether.Be non-combustible low boiling point solvent, safety performance is better, although methylene dichloride also has toxicity, we adopt encapsulation process, less to the Health hazard of operator.Methylene dichloride boiling point is 39.8 DEG C, highly volatile.
Diesel oil is hydrocarbon mixture material, volatilizees together with methylene dichloride, the Volatile Gas of generation, and synergy, can play good solute effect to the caking agent of the plastic film that metal sheet covers.
Place metal sheet 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.Then covered by sealed platform cover, casing is sealed, and to be annotated degumming agent of the present invention by degumming agent.The amount that each casing (box volume is about 2 cubic metres) adds degumming agent is 10-20L, does not need whole for sheet material submergence, then valve-off.Place 1-2h.Be vented by vent valve, open casing, just sheet metal can be taken out, at this moment, the plastic film on sheet material is separated with sheet material.Employing box sealing comes unstuck, and security is better, and the volume of the degumming agent added is few, and cost is low.
Beneficial effect: starting material of the present invention, safety 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.
Embodiment
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, vent valve 4, separation net 5, sealing-ring 6, channel-section steels 7.
The upper end case mouth of casing 1 is provided with flanging, arranges stiffening web between flanging and casing 1.Sealed platform cover 2 is hinged on one end of casing 1, and sealed platform cover 2 is placed on the flanging on case mouth, and flanging arranges sealing-ring 6, and when sealed platform cover 2 puts down, sealing-ring 6 plays the effect of seal case 1 and sealed platform cover 2.Three channel-section steels 7 are welded in the bottom surface of casing 1, and channel-section steel 7 extends along the width of casing 1.Three channel-section steels 7 are as the feet of casing 1.Other support component can also be set in the bottom surface of casing 1 certainly.
Sealed platform cover 2 or casing 1 are provided with degumming agent filler pipe, are preferably arranged on sealed platform cover 2, and two degumming agent filler pipes are set on sealed platform cover 2.This degumming agent filler pipe arranges degumming agent fill valve 3, and casing 1 or sealed platform cover 2 are provided with vapor pipe, and preferred vapor pipe is arranged on the bottom of casing 1.Vapor pipe is arranged vent valve 4, some separation nets 5 arranged by transverse bar and longitudinal rod longitude and latitude are placed with in casing 1, in casing 1, place layer of plate just place a separation net 5, upper and lower laminate material separates by separation net 5, and the Volatile Gas allowing degumming agent produce can penetrate on every laminate material.
After placing metal sheet or other sheet material, sealing seal cover board 2, open degumming agent fill valve 3 and to annotate in casing degumming agent, degumming agent is mixed by methylene dichloride and diesel oil, and the weight ratio of methylene dichloride and diesel oil is 10:0.5.
The volume of casing 1 is about 2 cubic metres, and the amount adding degumming agent is 10-20L.Degumming agent does not need whole for sheet material submergence.
Then close jelly fill valve 3, leave standstill 1-2h.
Open vent valve 4, drain the Volatile Gas of clean the inside, then open sealed platform cover 2, metal sheet is taken out, metal sheet with cover plastic film and be separated.
Embodiment 2
Other is identical with embodiment 1, unlike, jelly is mixed by methylene dichloride and diesel oil, and the weight ratio of methylene dichloride and diesel oil is 10:2.The amount of the degumming agent added is 20L.
Embodiment 3
Other is identical with embodiment 1, unlike, jelly is mixed by methylene dichloride and diesel oil, and the weight ratio of methylene dichloride and diesel oil is 10:0.8.The amount adding degumming agent is 10L.
Embodiment 4
Other is identical with embodiment 1, unlike, jelly is mixed by methylene dichloride and diesel oil, and the weight ratio of methylene dichloride and diesel oil is 10:1.2.The amount adding degumming agent is 15L.
The present invention is not limited to above-mentioned specific embodiment, should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.In a word, all technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
