Plastic road cones, also known as traffic cones, reflective road signs, etc., are a common traffic facility product, often used in highway intersections, toll booths, highways and national and provincial road construction sections, which have a clear warning effect on drivers, can reduce the degree of casualties to people and vehicles caused by the perpetrators, and form a safer protection.
PE plastic is polyethylene, which is a thermoplastic resin made by polymerization of ethylene. Polyethylene is odorless and non-toxic, feels like wax, and has excellent weather resistance. Polyethylene is divided into high-pressure ethylene and low-pressure ethylene. High-pressure ethylene was made by the British Brunner Mond Chemical Industry Company in 1933 using a high-pressure method, which means that high-pressure polyethylene is an important component of plastic road cones.
Masterbatch, the full name is masterbatch, also called color species, is a new type of special colorant for polymer materials, also known as pigment preparation. Masterbatch is mainly used in plastics. It is composed of three basic elements: pigment, carrier, and additive. It is an aggregate obtained by uniformly attaching an extraordinary amount of pigment to the resin. It can be called a pigment concentrate, so its coloring ability is higher than the pigment itself.
Defoamer, also known as defoamer or defoamer, will produce many foams that affect production during industrial production, and defoamers need to be added. It is widely used to remove harmful foams generated in the production process of textile sizing, food fermentation, biomedicine, petrochemical, papermaking, industrial cleaning, coatings, latex, sewage treatment and other industries.
1. Mixing, mix high-pressure polyethylene, masterbatch, defoamer and other raw materials evenly according to a certain proportion.
2. Extrusion: Extrude the uniform mixture through a certain pressure.
3. Mold molding: The extruded mixture is then molded.
4. Trimming: Trim some excess burrs with a knife. Put it aside to cool after trimming.
5. Add sand strips: Generally, the bottom of plastic road cones is sandy, so that the plastic road cones are more stable and not easily knocked down or blown down by strong winds.
6. Add reflective cone sleeves: The road cones themselves are made to be placed in some construction sites and large public places for traffic warnings. Adding reflective cone sleeves is to make the road cones reflect light under the illumination of car lights in the dark night to avoid traffic accidents.
1. Environmental protection, plastic road cones are made of high-pressure polyethylene and can be recycled. Damaged road cones can be recycled.
2. Safety, plastic road cones are brightly colored, with reflective cone sleeves on the surface. Whether it is day or night, the reflective effect is very obvious, which can serve as a good warning to moving vehicles.
3. Lightweight and economical: simple placement and easy operation. Road cones can be put together, and fifty piled together will not exceed 2 meters, which is very convenient for transportation.
4. It has good weather resistance, corrosion resistance, and is not easy to age.
5. Beautiful, non-fading, red and white, eye-catching colors, and a good warning effect. Reduce the accident rate.
Guangzhou will increase investment and construction of major infrastructure, and will invest 828.2 billion yuan to build 283 projects, including 28 intercity rail projects, and the investment amount accounts for nearly 40% of the total investment. The "Implementation Opinions of the Guangzhou Municipal People's Government on Accelerating the Construction of Urban Infrastructure" and the "Guangzhou 2014-2016 Important Infrastructure Project Plan" were reviewed and approved at the municipal government executive meeting on May 26, and were reviewed and approved again at the municipal party committee standing committee meeting yesterday.
The plan is divided into 12 major projects, a total of 283 projects, with a total investment of about 828.2 billion yuan, of which about 423.6 billion yuan is planned to be invested from 2014 to 2016. Including: international aviation hub port project, coastal main hub port project, railway main hub project, intercity urban rail transit project, high-speed road network project, information infrastructure project, energy security and new energy project, ecological facility project, environmental protection facility project, water conservancy facility project, municipal facility project and cultural facility project. Among them, cultural facility projects, in addition to the general cultural infrastructure, also include infrastructure content in the fields of science and technology, education, medical care and civil affairs. As one of the main products of transportation facilities, road cones play a great role in future infrastructure construction.
