The specific embodiment
[first embodiment]
First embodiment, shown in Fig. 1 (a) and (b), be meant and contain the surface that conducting liquid with interfacial active agent is sprayed on glass container 2, form the conductive layer 4 of pantostrat, perhaps form the conductive layer 4 ' of discontinuity layer, with Taic coating device liquid coating is sprayed on the conductive layer 4 of pantostrat again, perhaps be sprayed on the conductive layer 4 ' of discontinuity layer, form electrostatic spraying layer 6, Using such method forms application glass container 8 like this.
Wherein, Fig. 1 (a) is the application glass container that the conductive layer 4 by pantostrat constitutes, and Fig. 1 (b) is the application glass container that the conductive layer 4 ' by discontinuity layer constitutes.
One, glass container
1, shape
There is no particular restriction for the shape of glass container.Various bottle for cosmetics and all suitable applications of medicinal bottle such as bottle, square bottle, cylinder bottle, special-shaped bottle, square in addition, columnar, special-shaped various glasswares also are fit to application.
2, material
There is no particular restriction for the material of glass container.For example soda-lime glass container, borate glass container, lead glass container, phosphate glass container, lead-silica glass container etc. all are fit to application.
With regard to glass colour, water white transparency, painted transparent, the painted application that also all is fit to such as translucent.
Two, conductive layer
1, structure
Pantostrat or discontinuity layer
Shown in Fig. 1 (a) and (b), conductive layer is divided into pantostrat and discontinuity layer.The resistivity that the conductive layer of pantostrat can make glass container 2 surfaces is uniformity more, and formed electrostatic spraying layer 6 is more even, more stable.And the conductive layer of discontinuity layer can utilize the gap of self, makes electrostatic spraying layer 6 combine tightr, more firm with glass container 2 surfaces.
Specific insulation
The specific insulation of conductive layer should be controlled at 1 * 10
-4~ 1 * 10
7In the Ω .cm scope.
Its reason is as specific insulation being controlled at 1 * 10
-4Below the Ω .cm, just very high to the requirement of interfacial agent, there are a lot of interfacial agents just can not use.And specific insulation is 1 * 10
7More than the Ω .cm, it is unstable that the resistivity of glass surface will become, and the electrostatic spraying layer of Xing Chenging is also just unstable thereafter, and coating thickness has deviation, and is inhomogeneous.
So, the specific insulation of conductive layer is controlled at 1 * 10
-4~ 1 * 10
3In the Ω .cm scope is comparatively ideal, is controlled at 1 * 10
-4~ 1 * 10
2Then even more ideal in the Ω .cm scope.
The specific insulation available volume determination of resistivity instrument of conductive layer is measured.
The thickness of conductive layer
Thickness by the conductive layer that forms of conduction liquid should be controlled in 0.01 ~ 10 mu m range.
Its reason is the thickness such as the less than 0.01 μ m of conductive layer, and the specific insulation on glass container surface will be very unstable, the easy became uneven of electrostatic spraying layer.And when the thickness of conductive layer surpassed 10 μ m, the formation of conductive layer and dry the need spent the more time.
So is comparatively ideal with the THICKNESS CONTROL of conductive layer in 0.02 ~ 5 mu m range, is controlled in 0.05 ~ 1 mu m range then even more ideal.
The thickness available electron microscope or the blooming analyzer of conductive layer are measured.
2, conduction liquid
Conduction liquid is the aqueous solution that contains interfacial agent.The addition of interfacial agent should be controlled in 0.1 ~ 50 weight % scope with respect to the total amount of conduction liquid.
Its reason is the addition such as the less than 0.1 weight % of interfacial agent, and the specific insulation on glass container surface will be very unstable, the easy became uneven of electrostatic spraying layer.And when the addition of interfacial agent surpasses 50 weight %, can cause the glass container surface and the bonding force of electrostatic spraying layer significantly to descend, and also can significantly prolong the drying time of conductive layer.
So the addition of interfacial agent conducts electricity the total amount of liquid relatively, it is comparatively ideal being controlled in 0.5 ~ 20 weight % scope, is controlled in 1 ~ 10 weight % scope then even more ideal.
The solvent available water of interfacial agent, but perfect method is with isopropyl alcohol or alcohol interfacial agent to be dissolved earlier, and then add an amount of water.
Its reason is can dissolve interfacial agent fast with isopropyl alcohol or alcohol, and the rate of drying of conduction liquid is also fast, can improve film bonding force with the glass container surface of coating.
So it is comparatively ideal that the mixed weight ratio of interfacial agent and alcohol cpd is controlled in 20: 80 ~ 80: 20 scopes, it is then better to add an amount of water after mixing again.
Interfacial agent can be selected a kind of from nonionic class interfacial agent, anionic species interfacial agent, cationic interfacial agent, both sexes interfacial agent or select more than one to form.
Reason is the better performances of above-mentioned interfacial agent, for instance, at most only needs to add about 10 weight %, can make the specific insulation uniformity on glass container surface.
From the selection of interfacial agent, should comprise nonionic class interfacial agent, cationic interfacial agent, the interfacial agent that combines.
Reason is that the performance of the interfacial agent that combines is better, for instance, at most only needs to add about 7 weight %, can make the specific insulation uniformity on glass container surface.
When nonionic class interfacial agent and the combination of cationic interfacial agent, nonionic class interfacial agent is selected the polyoxyalkylene ether compound, and the cationic interfacial agent selects ammonium chlorine compounds, ammonium Sulfates compound, ammonium Nitrates compound then better.With respect to polyoxyalkylene ether compound 100 unit of weights, the addition of cationic interfacial agent can be controlled in 1 ~ 50 unit of weight scope.
The molecular formula of polyoxyalkylene ether compound is as follows:
R1-O-(R2-O)nH???????(1)
In the molecular formula (1), R1 represents to have substituent, and carbon number is 3 ~ 15 alkyl, or has substituently, and carbon number is 6 ~ 15 aromatic series carbonization hydroxy, or has substituently, and carbon number is 4 ~ 15 multiple plain aromatic series cyclic group.
R2 represents to have substituent, and carbon number is 1 ~ 100 thiazolinyl.
N represents the integer from 1 ~ 100.
The polyoxyalkylene ether compound has: polyethylene glycol oxide ten diether compounds, PPOX ten diether compounds, polyethylene glycol oxide margaron compound, polyoxyethylene glycerol stearyl ether compound or the like, can select that wherein one or two or more kinds is used in combination.
Above polyoxyalkylene ether compounds property is more superior, as interfacial agent, at most only needs to add about 5 weight %, can make the specific insulation uniformity on glass container surface.
The specific insulation of conduction liquid (aqueous solution state) should be controlled at 1 * 10
-4~ 1 * 10
7In the Ω .cm scope, be controlled at 1 * 10
-3~ 1 * 10
6Then comparatively desirable in the Ω .cm scope, be controlled at 1 * 10
-2~ 1 * 10
5Then even more ideal in the Ω .cm scope.
The specific insulation of liquid (aqueous solution state) of will conducting electricity is controlled in this scope, and the specific insulation that can make the glass container surface is uniformity more.
3, electrostatic spraying layer
The thickness of electrostatic spraying layer
The coating thickness that liquid coating forms, promptly the thickness of electrostatic spraying layer should be controlled in 5 ~ 200 mu m ranges.
Reason is coating thickness less than 5 μ m, and the mechanical strength of coating is low, and comes off from the glass container surface easily.And coating thickness is when surpassing 200 μ m, and the formation of coating and dry required time are oversize.
So it is desirable that coating thickness is controlled in 10 ~ 100 mu m ranges, be controlled in 20 ~ 50 mu m ranges then even more ideal.
Liquid coating
The kind of a, liquid coating
There is no particular restriction for the kind of liquid coating, and alkyd resins, epoxy resin, allyl resin, vinyl, polyurethane resin, silicone resin, mylar, phenolic resins or the like are for example arranged, and can therefrom select.
Curing agent can be selected ammoniate, phenolic compound, isocyanic acid compound, polyamide compound etc. for use.
B, curable resin
The resin kind of liquid coating should be selected thermohardening type resin or uv curing resin.Its reason is to adopt gel-type resin, can improve and the glass container surface between bonding force, formed film coated surface protectiveness is strong.When adopting the thermohardening type resin, available heating furnace is heating and curing, and makes liquid coating be solidified into coating.When adopting ultraviolet curing resin, available ultraviolet ray irradiation makes liquid coating be solidified into coating fast.
C, viscosity
The viscosity of liquid coating (25 ℃) should be controlled at 5 ~ 100, in the 000mpa.s scope.
Its reason is the viscosity such as the not enough 5mpa.s of liquid coating, uses difficulty, and coating thickness is too thin.And when the viscosity of liquid coating surpassed 100.000mpa.s, coating thickness was too thick, and coating is difficult to the nozzle by electrostatic spraying in other words.
So it is desirable that the viscosity of liquid coating (25 ℃) is controlled in 10 ~ 10.000mpa.s scope, is controlled at 100 ~ 5, then even more ideal in the 000mpa.s scope.
[second embodiment]
Second embodiment is meant on the glass container surface, constitutes pantostrat earlier by conduction liquid, or the conductive layer of discontinuity layer, constitutes the electrostatic spraying layer by liquid coating again, and Using such method forms the manufacture method of application glass container.
It comprises two operations.
First operation is containing conducting liquid with interfacial active agent, be sprayed on the glass container surface after atomizing is handled, forming conductive layer.
Second operation is the flow sheet glass container.STEP2 is exactly the conductive processing operation among Fig. 2.STEP4 is exactly the electrostatic spraying operation.Be decorated with the STEP3 drying process among Fig. 2 between STEP2 and the STEP4, but in the actual production because of conductive layer air dry soon, thereby also can save this operation.
1, first operation (conductive processing operation)
1. conductive processing device
Used conductive processing device in the conductive processing operation can adopt the conductive processing device of general conduction, also can adopt the conductive processing device 10 shown in Fig. 3 (a) and (b).The operation principle of conductive processing device 10 is to extract the conduction liquid in the hold-up tank out atomizing, ejection in atomizing case 61, atomizing particle size will be controlled in the prescribed limit, glass container on the guipure 69 passes through atomizing case 61 with certain speed, atomizing conduction liquid forms conductive layer just equably attached on the glass container surface.
Below by Fig. 4 (a) and (b), be described in further detail with regard to the operation principle of conductive processing device 10.Vaporific treatment fluid after atomizing is handled, from nozzle 81 ejections, meanwhile blender gas 83 enters atomizing case 61, and vaporific treatment fluid is stirred on the limit, and the moving vaporific treatment fluid of sideband advances along the direction of arrow EP91 in passage 99.The atomizing case 61 passage 99 inwalls on, be provided with semicircular, fusiform atomization particle cowling panel 85.In the vaporific treatment fluid, particle diameter surpasses the particle of setting, in advancing, can collide with cowling panel 85 and passage 99 inwalls, and attached on cowling panel 85 and passage 99 inwalls, drip gradually then, the base plate of atomizing case 61 is skewed, and the vaporific treatment fluid that drips confluxes, and the back is concentrated flows out from discharge gate 89, can give recycling.
The particle of particle diameter in the setting scope along with blender gas 83 advances, blows out from blow-off outlet 97 in passage 99.Shown in Fig. 4 (a), glass container 8 is along with guipure 69 passes through blow-off outlet 97, and the vaporific treatment fluid of particle diameter in the setting scope just blows to be paid on glass container 8 surfaces.Because all there is blow-off outlet 97 both sides of glass container 8, thereby vaporific treatment fluid can cover glass container 8 surfaces very equably.
Structure and operation principle according to conductive processing device 10, when the spraying of conduction liquid, can remove the undesirable conduction liquid of particle diameter, the satisfactory conduction liquid of particle diameter is blown pay on the glass container surface, the conductive layer thickness uniformity of Xing Chenging like this, so the specific insulation on glass container surface is uniformity also, and specific insulation is very stable.
Because it is little to form the average grain diameter of vaporific conduction liquid of conductive layer, so conductive layer need not be provided with a drying process specially, in transmitting the way, it is with regard to air dry.
2. conduct electricity the quantity for spray of liquid
The quantity for spray (unit interval) of conduction liquid should be controlled at 1 ~ 100cm
3In/minute the scope.Its reason is the not enough 1cm of the quantity for spray of conduction liquid
3/ minute, be difficult to hold at glass
The device surface forms thickness uniform conductive layer, and the specific insulation on glass container surface is also unstable, so the thickness of the final electrostatic spraying layer that forms is also inconsistent.And the quantity for spray of working as conduction liquid surpasses the 100cm3/ timesharing, and the bonding force on electrostatic spraying layer and glass container surface significantly reduces, and obviously prolong the drying time of conductive layer.
So the quantity for spray (unit interval) of conduction liquid is controlled at 10 ~ 70cm
3In/minute the scope is desirable, is controlled at 20 ~ 50cm
3/ minute then even more ideal.
3. conduct electricity the average grain diameter of liquid
The average grain diameter of the conduction liquid after atomizing is handled should be controlled at below the 100 μ m.
Its reason be the conduction liquid after atomizing is handled average grain diameter as 100 μ m with
Down, the specific insulation on glass container surface will be unstable, also can't form the electrostatic spraying layer of stable thickness uniformity certainly.In addition, because the average grain diameter of conduction liquid is more than 100 μ m, formed conductive layer drying is difficulty also, easily produces bald head, unequal shortcoming.
If yet the average grain diameter of the conduction liquid after atomizing is handled is too little, also can cause certain difficulty.The conductive layer required time that for example forms specific thickness on the glass container surface is oversize, operates difficult.Very high to conductive processing device requirement itself in other words, make the structure of conductive processing device become very complicated.
In sum, it is desirable that the average grain diameter of the conduction liquid after atomizing is handled is controlled in 5 ~ 50 mu m ranges, is controlled in 10 ~ 30 mu m ranges then even more ideal.
Fig. 5 and Fig. 6 are the particle size distribution figures that adopts the conduction liquid that the laser class sedimentograph records.Fig. 5 represents the particle size distribution figure of the conduction liquid of particle diameter in institute's definite value scope, and Fig. 6 represents the particle size distribution figure of particle diameter at the extraneous conduction liquid of institute's definite value.Fig. 5, among Fig. 6, left vertical pivot represents in the entire amount that the frequency of certain specified particle diameter (%), right vertical pivot are represented the accumulation (%) of the frequency of certain specified particle diameter.
Use size distribution conduction liquid as shown in Figure 5, to the glass container spraying, it is uniform to form thickness on the glass container surface, the conductive layer of no alopecia areata.And use size distribution conduction liquid as shown in Figure 6, to the glass container spraying, the conductive layer became uneven of formation has alopecia areata, and the yield of conduction liquid also increases.
So from the forming efficiency of conductive layer, shaped state considers that the average grain diameter after the atomizing of conduction liquid is handled should be controlled at below the 100 μ m.
The average grain diameter of conduction liquid can be measured with laser class particle size determination instrument or infra red type sedimentograph.
4. the drying process of conductive layer
Before the electrostatic spraying operation, also can as shown in Figure 2 a conductive layer drying process (STEP3) be set.Its objective is the moisture of removing in the conductive layer, and regulate the specific insulation of conductive layer.
The useful dry air glass-blowing of concrete grammar container is perhaps used 30 ~ 100 ℃ temperature heating glass container, and makes bottle rotation thermally equivalent, and can make glass container pass through decompression cabinet, makes glass container be in decompression state or the like.
As previously mentioned, vaporific conduction liquid after atomizing is handled, if average grain diameter below 100 μ m, formed conductive layer also need not specially be provided with a drying process, moisture can be fully removed in air dry, specific insulation also can be controlled in the prescribed limit.
2, second operation (electrostatic spraying operation)
1. Taic coating device
The Taic coating device that uses in the electrostatic spraying operation, the electrostatic spraying gun of called optical imaging just, electrostatic spraying gun 100 for example shown in Figure 7 are exactly an example wherein.
Also have high-pressure electrostatic supply unit 110 in the rifle body 101, coating is supplied with through hole 104 etc.
More even for the coating that can make the electrostatic spraying gun ejection, also can make rotating nozzle to coating spray-hole 115 as shown in Figure 8, the air of air jet hole 108 ejections, blow rotating nozzle 115 around the axle center rotation, the centrifugal force that utilizes rotation to produce can make the spraying of coating more even.
In addition, as shown in Figure 8, coating is supplied with through hole 104 do curl, can make the electrostatic spraying gun miniaturization.
2. the distance between first operation and second operation
Distance between first operation and second operation should be controlled in 0.5 ~ 20m scope.
Its reason be distance between first operation and second operation as less than 0.5m, even if the average grain diameter of vaporific conduction liquid is tiny again, the drying of conductive layer is still insufficient state, it is just low with the bonding force on glass container surface to film.And on the other hand, the distance between first operation and second operation is greater than 20m, and the required place of whole coating process is just too big.
So it is desirable that the distance between first operation and second operation is controlled in 1 ~ 10m scope, be controlled in 2 ~ 5m scope then even more ideal.
[example]
Below, be described in more detail with regard to content of the present invention by example.Certainly, range of application of the present invention can not be confined to the example lifted, according to actual conditions, can do suitably change in purpose scope of the present invention.
