Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid type mixing device capable of controlling flow rate, and a liquid type lane-

The present invention relates to a liquid-type mixing apparatus capable of controlling the flow rate and a liquid-type lane-painting apparatus including the same, wherein it is possible to measure the flow rate of two kinds of paints and adjust the flow rate, Type liquid mixing apparatus and a liquid-type lane-changing apparatus including the same.

Generally, roads are marked with yellow or white lanes by one or two lines of dashed and solid lines. Such lane paintings spray a certain amount of paint on the road.

These lacquer coating materials are classified into one kind of room temperature drying type road marking paint, two kinds of receiving mold surface marking paint, three kinds of heating type road surface marking paint, four kinds of adhesion marking type road surface marking paint, five kinds of room temperature hardening type plastic Paint and so on.

In particular, in the case of the above-mentioned five kinds of room temperature curable plastic coatings, an acrylic resin is mixed with a methyl methacrylate (MMA), a butyl acrylate monomer (BAM) and a 2- (2-Ethylhexyl acrylate monomer, 2-EHA), the base and the curing agent were homogeneously mixed using a benzoyl peroxide (BPO) So that the paint can be dried quickly. That is, the above-mentioned five kinds of room temperature curing type plastic coatings are excellent in abrasion resistance and durability, and the fixing performance of the glass balls is superior to that of one kind to four kinds of coatings.

Here, it is general that the flow control unit and the static mixer, which are two liquid mixing units for mixing at least two kinds of flow components, mix the liquid type liquid crystal type liquid crystal material with a curing agent or mix them with other liquid crystal .

(50%) system and 98: 2 system paint (98%), which is a 1: 1 type of system (46%) + hardening agent (4% %): Curing agent (2%), and the curing agent can be divided into a liquid curing agent and a powder curing agent.

In some applications where such a static mixer is used, it is desirable to mix the two components in a static mixer and then spray onto a substrate. To this end, the two components can be sprayed at the mixer outlet by the action of a medium such as air and applied to the desired substrate in the form of a spray jet or spray mist.

Of these liquid type mixing apparatuses, most of the manual lane painting apparatuses are mixed by a static mixer and finally sprayed by the spray gun. In particular, coating media with higher viscosity, such as polyurethane, epoxy resin, or similar materials, may be utilized in the art.

However, such a conventional static mixer may be reversed according to the supplied pressure, and when the high-viscosity paint is injected at a high pressure under the same pressure, due to the difference in the flow velocity (depending on the Mach- There is a problem in that they are not completely mixed.

Even if the check valve is provided, the initial mixing may not be performed due to the difference between the composition liquid A and the coating liquid B, which are high-viscosity coating materials that have passed through the check valve, resulting in incomplete curing or delayed curing time Problems may arise.

Also, there may be a large variation in the viscosity change of the Composition Solution A and the Composition B depending on the difference in the application temperature. For example, in the case of a room temperature curing type plastic paint, the viscosity is 90Ku when the morning temperature is 15 ° C and the viscosity is 80Ku when the temperature is 25 ° C at lunch. In other words, there may be a difference in viscosity between the composition A paint and the B paint depending on the temperature change.

As in this case, there is a problem that the viscosity changes frequently due to the temperature change, resulting in a difference in flow rate. As a result, the two coating materials (composition liquid) are not mixed well or are hardly mixed.

Further, when the first paint and the second paint are pressure-fed under the same pressure (for example, at a pressure of 130 Bar), even if a paint having the same viscosity is used, the friction of the fluid in the moving parts 15 and 25, Differences in ideal conditions may occur due to reasons, which may result in a change in the flow rate of the first paint and the second paint.

Therefore, in order to obtain the actual flow rate, it is necessary to measure the actual pressure and flow rate of the fluid flowing when it is injected into the nozzle tip of the jet part (60, which may be implemented in the form of a spray gun).

For example, when the first paint and the second paint are pumped through the pump units 30 and 40 at a pressure of 130 bar, the pressure must be maintained at 130 Bar to the jetting unit 60, The pressure of the flowing velocity is reduced from 110 Bar to 120 Bar.

That is, since there is a difference in flow rate between the first paint and the second paint, the initial injection tends to spray the first paint or the second paint in a state where the first paint and the second paint are not mixed.

In order to solve the above problems, the liquid type lane marking apparatus 1 according to the embodiment of the present invention stores the first paint and the second paint in the chambers 13, 23 at the same pressure.
