How to produce traffic road marking thermoplastic paint
Road marking thermoplastic paint mainly include resin, titanium dioxide, liquid dioctyl ester, silica sand, calcium powder, glass beads, etc.
1. choose the special road marking thermoplastic paint mixer equipment machine for the production of hot-melt thermoplastic marking paint.
Since the hot-melt thermolplastic marking paint is a mixture of dry powder and a small amount of liquid, the stirring resistance of the hot-melt marking paint is large, and you must choose a special mixer for the melting road marking thermoplastic paint. According to our experience, the U shape low speed ribbon mixer is an ideal choice for the mixing production of thermoplastic road marking paint, high speed mixer atucally can not reach the best mixing uniformity for the production of road marking paint. The U shape ribbon mixer is fixed automatic liquid spraying device which can spray the dioctyl ester evenly during mixing.
2. Production of traffic road marking thermoplastic paint
Thermoplastic marking paint mixers can be divided into 1 ton and 2 tons mixers according to their mixing capacity at a time. A large output mixer can be customized according to the output requirements of different customers, such as 3-5 tons mixers, even larger output can also be specially produced in our factory. No matter what output capacity of mixer, the operation process is similar, the whole process is as follows:
Prepare raw materials as formula.
Except the large-scale fully automatic Thermoplastic marking paint production line which automatically measures and distributes the proportions, the small prodution uses manual batching of raw materials proportion and puts the proportioned raw materials into the mixer manually for mixing production. The Thermoplastic marking paint mixer can mix powder materials and liquid materials.
Materials feeding.
The equipment equipped with a screw feeder which directly lifting the materials from ground to mixer. There are two feeding methods, one is to use a bucket elevator for vertical feeding, and the average feeding speed is 7 kg/s (tested with 200 mesh materials); the other is to use screw conveyor for feeding inclinedly, this feeding equipment is low cost, easy production and equipment maintenance.
Mixing.
The mixing work is finished by thermoplastic paint mixer. Thermoplastic paint mixer is normally use single shaft ribbon type mixer, mixing cycle time is about 5 minutes.
Packaging.
If the mixer equipped with a finished product silo, the air-flow valve port automatic packaging machine is connected to the finished product silo. After the material all discharged from the finished product silo, materials will be released to the packaging machine and the work only need one button operation to finish packing. If the equipment doesn't have a finished product silo, the valve port packaging machine is directly linked with the mixer discharge port for packaging. This packaging method is fast, time-saving and labor-saving.
Produce high quality traffic road marking thermoplastic paint
The production process of road marking thermoplastic paint is basically a physical mixing process. However, it is not a simple mixing process of various ingredients because you need to ensure the uniform mixing of various raw materials and the state of tiny core-coated powder with resin or glass beads as the core. Around the core is the adhesive layer of additives and pigments, and the outer layer is the adhesive and dispersion layer of fillers. Note: add qualified raw materials according to the product formula and recommended dosage, if too much adding of some materials, it is easy to cause yellowing.
Because the proportion of color pigments and additives in the road marking thermalplastic paint is small, to ensure the uniformity of the road marking paint quality, the mixing uniformity of these two components must be ensured, so in the production process should be firstly add the resin to the machine and coloring pigments to make it evenly mixed, during the whole production process, appropriate amount of high-efficiency fluorescent whitening agent should be mixed evenly. Generally, adding about 200g per ton road marking paint, but, because of the different production formulas, personal adjustment is required. It must be a gradual spraying method.
There are also many other output capacity traffic road marking thermopastic paint production line can be chose. Contact us now for more information
