II. Q&A about Products

1. What products does Changda have?

Main products: MMA two-component series markings; also produces: thermoplastic road marking paint, cold paint, water-based paint, etc. All products come with supporting equipment.

2. What is Changda MMA?

In recent years, Changda has devoted itself to researching and developing high-performance products to solve many problems existing in the road marking industry, such as easy pollution of urban markings, easy detachment of cement pavement markings, and poor nighttime reflectivity of highway markings. The main products include: MMA anti-fouling road marking paint, MMA high-reflective road marking paint, MMA cement pavement dedicated road marking paint, MMA colorful anti-skid pavement paint, and MMA snow region road marking paint.

3. What are the main components of A and B in Changda MMA?

Component A is a base material containing MMA resin, and Component B is a base material containing a curing agent. A chemical crosslinking reaction occurs during film formation, greatly improving the adhesion of the marking and the bonding strength to glass beads, making the marking film more dense and unaffected by temperature changes, thereby greatly improving the durability of the markings. Facts have proved that markings using DEGAROUTE® active resin as a basic component can last for at least 3 years.

4. Why does Changda MMA anti-fouling road marking paint have good anti-fouling properties, while traditional thermoplastic road marking paint has poor anti-fouling ability?

First, MMA resin is an irreversible resin, and the markings are formed by a chemical reaction. After the chemical reaction, it is no longer affected by temperature changes. It will not crack at low temperatures, nor will it soften at high temperatures. It does not adhere to dust like thermoplastic road markings; secondly, the marking paint material is fine and dense, and the markings are highly dense after film formation, making it difficult for dust to penetrate into the marking coating;

Second, during the construction of anti-fouling markings, since the construction area is an urban road, urban roads generally have better lighting, and the marking reflectivity indicators can be weakened. During the daytime, the anti-fouling markings are a clean white line. At night, because no glass beads are sprinkled on the marking surface, the marking surface reflects light from car lights and street lights like a mirror, effectively separating the lanes.

Thermoplastic road marking paint uses C5 petroleum resin, which is a thermoplastic resin with reversibility. This means that the thermoplastic road markings are heated and melted, then constructed onto the road surface, and solidify after cooling. However, in summer, when the temperature is high, it easily softens again. When softened, the markings easily have dust and other debris pressed into them by external forces such as cars, polluting the markings; In addition, thermoplastic markings are relatively rough, and it is difficult to clean impurities that penetrate into the markings. The problems of thermoplastic markings are particularly evident in the north; even in the south, where there is sufficient rain, although the anti-fouling effect is better than in the north, these problems still exist.

5. How does Changda MMA high-reflective road marking paint achieve high reflectivity?

First, Changda MMA Road Marking Pioneer high-brightness road marking paint uses imported German MMA resin as the main raw material. The marking film formation is chemically cured, and during the reaction, the glass beads sprinkled on the marking surface are firmly solidified into the marking as a filler, achieving long-lasting firm adhesion to the glass beads;

Second, carefully selected glass bead manufacturers to improve glass bead quality;

Thirdly, the high wear resistance of the marking ensures that the high-reflective marking not only has good reflective effect, but also can achieve long-lasting reflection; relevant data show that the wear resistance of 0.6mm MMA high-brightness marking coating is comparable to that of 2mm hot-melt marking coating. In some road sections with large traffic flow, the scraping coating process is used, and the coating thickness is 1.2-1.5mm, which can greatly improve the service life of the marking.

Fourthly, in some special road sections, such as the Northeast, Yunnan, Guizhou and Sichuan where snow removal is serious, we have developed a concave marking, which can be figuratively described as a channel steel-like structure. While enhancing the overall strength of the marking, it can also effectively ensure that the surface-scattered glass beads will not be scraped off by external forces such as graders and snow plows, thus enabling the marking to reflect light efficiently for a long time.

6. Why is the adhesion of ChangdaMMA series products better?

ChangdaMMA series products have good adhesion and good adhesion on different materials road surfaces, mainly through two aspects:

First, strong penetration: The product is made of Evonik special resin, and the molecular weight of a single component is very small, with strong physical permeability (like scattering many "nails" on the road surface).

Second, cross-linking: In the process of condensation and solidification, chemical cross-linking reaction occurs between the two components (a kind of polymerization reaction, like nailing nails to the ground and then connecting them into a network horizontally and vertically), so that the marking is firmly bonded to the road surface and is difficult to fall off.

Combining China's national conditions and years of practice, Changda Company has conducted special research on the adhesion problem of cement pavement. Combining its own patents (double-component road marking coating for cement pavement and its preparation method, patent No.: 508649), the product has been improved targetedly, and MMA cement pavement special marking coating and ChangdaMMA road marking pioneer-MMA cement pavement special marking coating have been launched to fully meet the marking use needs of cement pavement, airports, ports, docks, etc.

7. What is the difference between ChangdaMMA colored pavement antiskid coating and epoxy resin antiskid marking?

(1) Epoxy resin type:

Advantages: Low price

Disadvantages:

a. Cracks: Cracks may appear soon after construction, especially on newly constructed asphalt pavements.

b. Discoloration: Epoxy resin has poor weather resistance and yellowing reaction. With the passage of time, no matter what color it is adjusted to at the beginning, it will turn yellow after a period of time. This is a universal problem.

c. Powdering: Another defect of epoxy resin itself is poor powdering resistance. After a short time, powdering and falling off will occur, and the falling off phenomenon will be more serious after more than 1.5 to 2 years.

d. Long curing time: The curing time is related to the temperature. When the temperature is higher than 30 degrees in summer, it is generally about 20 minutes, and when the temperature is lower than 10 degrees, it may reach more than 8 hours.

(2) MMA reactive acrylic type:

Advantages: It basically does not have the disadvantages of epoxy resin, such as cracks, discoloration and powdering. The main reason is that the resin has certain flexibility after reaction, and it is as consistent as possible with the flexibility of the asphalt pavement, so the crack problem is solved. The curing time is basically about 2 hours.

Disadvantages: High price

8. Why is the price of ChangdaMMA products higher than that of other manufacturers?

First: It uses imported MMA resin produced by Evonik in Germany. At present, only two companies in China use this imported resin, one is Hepu Chemical, and the other is Changda. Other domestic companies are self-synthesized. Due to the large difference in raw materials, the price of finished products is also large;

Second: During construction, attention is paid to the cleaning of marking lines and the construction of special primers. Units with low bids will omit these two steps, especially the cost of special primers is 4-5 yuan / square meter;

Third: The thickness of the marking film is low. In low-price construction, it is only 0.4mm or even thinner. In this way, the coating may be reduced by 0.2mm per square meter compared with the required 0.6mm, and the material can be saved by about 0.4kg, which reduces the unit price by about 10 yuan.

ChangdaMMA marking products require careful attention and careful organization in the aspects of coating and construction, and do not use huge profits or cutting corners as a means of profit, in order to effectively solve the problems existing in the application of marking lines.
 

III. Construction Q&A

1. How many construction methods are there for ChangdaMMA series markings? What is the construction process?
