Ⅱ.FAQ about the product
1. What are the products of Changda?
The main products: MMA two-component series of marking; at the same time production: thermoplastic road marking paint, cold paint, water-based paint. All products are supplied with supporting equipment.
2. What is the product of MMA?
In the past few years, we have been concentrating on solving many problems in the marking industry, such as easy pollution of urban marking lines, easy peeling of cement pavement markings, and poor nighttime reflective performance of expressway markings. Including: MMA anti-fouling road marking paint, MMA high-light road marking paint, MMA concrete road marking paint, MMA colorful anti-skid road marking paint, MMA snowy road marking paint.
3. What are the main components of A and B in MMA?
The component A is a binder containing MMA resin, and the component B is a binder containing a curing agent. A chemical crosslinking reaction occurs during film formation, which greatly improves the adhesion of the marking line and the bonding strength to the glass beads, so that the marking film is coated. It is more compact and unaffected by temperature changes, thus greatly improving the durability of the marking. It has been proven that the markings with DEGAROUTE® reactive resin as the basic component should be used for at least 3 years.
4. Why is the anti-fouling property of the Changda’s MMA product better? Why is the traditional hot melt coating poor in dirt resistance?
First, MMA resin is an irreversible resin. The marking line is chemically formed into a film. At the same time, it is no longer affected by temperature changes after chemical reaction. It will not crack when the temperature is too low, nor will it become soft when the temperature is too high. Therefore, it does not adhere to dust like the thermoplastic marking line; secondly, the marking material of the marking line is fine, the denseness of the marking line after film formation is high, and the dust is not easily infiltrated into the marking layer coating;
Second, when the construction of the anti-fouling marking line is urban road, the urban road is generally well illuminated, and the reflective performance index of the marking can be weakened. The anti-fouling marking line after construction is a white marking line during the day, due to the evening. The marking line does not cover the glass beads. The surface of the marking line is specularly reflective to the lights such as the headlights and street lamps. Sitting on the marking line of the car is as bright as a mirror, and effectively functions as a separation of the marking lanes.
The thermoplastic coating uses C5 petroleum resin, which is a thermoplastic resin and has reversibility. That is to say, the thermoplastic marking line is heated and melted and then applied to the road surface to cool and solidify into a marking line, but it is easy to soften again when the temperature is high in summer. The softened marking line is easy to push dust and other debris into the marking line under the action of external force such as automobile, and pollute the marking line; in addition, the thermoplasticing marking line is relatively rough, and the marking line is not easy to clean after infiltrating impurities. The problem of the thermoplastic marking line itself is particularly obvious in the north, that is, in the case of sufficient rain in the south, although the anti-fouling effect of the marking line is better than that of the north, there are also such problems.
5. How does the MMA high-reverse cursor line coating achieve high reflectivity?
First, the MMA road sign pioneer highlight line paint is based on Germany imported MMA resin as the main raw material, the marking film is chemically cured to form a film, in the reaction, the glass beads can be sprinkled on the surface of the marking as a filler. Firmly firmly in the marking line, achieving long-lasting firm adhesion to the glass beads;
Second, select glass beads manufacturers to improve the quality of glass beads;
Third, the high wear resistance of the marking line ensures that the high anti-cursor line not only has good reflection effect, but also achieves long-term reflection; the data shows that the 0.6mm MMA high-elastic marking coating can be quite wear-resistant for the 2mm coating of the thermoplastic marking. In some road sections with large traffic flow, the coating process is applied, the coating thickness is 1.2-1.5mm, and the life of the marking line can be greatly improved.
Fourth, in some special road sections, such as the northeast and Yunnan-Guichuan where the snow removal is more serious, we have developed a concave marking line, which is like a channel-like structure, in the case of enhancing the overall strength of the marking line. It can also effectively ensure that the surface of the glass beads will not be scraped off by external forces such as graders, snow removal shovel, etc., so that the marking line will be highly reflective for a long time.
6. Why is the adhesion of the MMA series products better?
The long-term MMA series products have good adhesion and good adhesion on different materials, mainly through two aspects:
First, strong penetration: The product is produced with Evonik special resin. The molecular weight of the single component is very small and has strong physical permeability (like many "nails" are scattered on the road surface).
Second, cross-linking: chemical cross-linking reaction between two components during coagulation and solidification (one kind of polymerization, like nailing nails to the ground, then connecting the webs vertically and horizontally), thus making the marking Strongly combined with the road surface, it is difficult to fall off.
In combination with China's national conditions and years of practice, Changda Company conducted a special study on the adhesion of cement pavement, combined with its own patent (two-component road marking paint for cement pavement and its manufacturing method, patent number: No. 508649) Targeted improvement, the introduction of MMA cement pavement special marking paint, and the MMA road sign pioneer-MMA cement pavement special marking paint to fully meet the requirements of cement pavement, airport, port, dock and other marking lines.
7. What is the difference between the MMA color road anti-skid coating and the epoxy resin anti-skid marking?
Advantages: Cheap price
a. Cracks, cracks may occur shortly after construction, especially on new asphalt pavements.
b. Discoloration: The epoxy resin has poor weather resistance and yellowing reaction. With the passage of time, no matter whether it is adjusted to red or other colors at the beginning, yellowing will occur in some time. This problem is a common problem.
c. Powdering: There is also a defect in the characteristics of epoxy resin, which is poor in powdering resistance. When the time is a little longer, powdering and shedding will occur. Generally, the phenomenon of shedding is more serious after 1.5 to 2 years.
d, the curing time is longer: the curing time is related to the temperature. When the summer temperature is higher than 30 degrees, it is generally about 20 minutes. When the temperature is lower than 10 degrees, it may reach more than 8 hours.
(2) MMA reactive acrylic:
Advantages: Corresponding to the shortcomings of epoxy resin, it basically has no crack, discoloration or chalking phenomenon. The main reason is that the resin has a certain flexibility after the reaction, and is as flexible as possible with the asphalt pavement, so the crack problem is solved. The curing time is basically about 2 hours.
Disadvantages: higher price
8. Why is the price of the MMA product higher than other manufacturers?
First: the MMA resin produced by the German company Evonik is used. At present, there are only two domestically-produced resins, one is Hepu Chemical, the other is Changda, and other domestic companies are self-synthesized, due to the raw material gap. Larger, so the price gap between finished products is also large;
Second: pay attention to the construction of marking line cleaning and special undercoating during construction. The unit that reports low price will omit these two steps, especially the cost of special coating agent will be 4-5 yuan/square meter;
Third: the thickness of the marking film is only 0.4mm or even thinner when the construction is low, so the coating may be reduced by 0.2mm per 0.6mm of the square meter, the material can save about 0.4kg, and the unit price is reduced by about 10 yuan.
Long-term MMA marking products require careful and careful organization in the coating process and construction process, and do not use profiteering or cut corners as a means of profit, in order to effectively solve the problems in the application of marking.
3.The construction of the question and answer
1. How many types of construction methods can be used for the MMA series of marking lines? What is the construction process?
At present, it is mainly composed of direct spraying, screeding, and composite marking construction.
Construction process: closed traffic - release line - cleaning the road surface - construction special coating agent - preparation of paint - coating marking line - correction - release traffic
2. Is the construction equipment a supporting professional equipment? Can long-term rental and external sales?
