And high qualityMMAComparison of two-component markings，Hot melt marking exists in the applicationA seriesQuestion：
AboutConstruction methodDuring hot melt construction，Liquefied gas is required to heat the material to 180℃Above，Fire and explosion hazards exist in open fire operation，Burn and scald accidents often occur.。In addition，The daily feeding of burning personnel is up to 120-200 packs（25kg/The bag），Most of them adopt hand-push construction.，Perennial construction may lead to occupational diseases such as lumbar spine problems and alopecia areata.。Priming oil is required for hot melt construction，Add process，Complicated construction。In contrast，MMATwo-component marking shall be constructed at normal temperature.，The daily consumption is 20 barrels（25kg/Bucket）Left and right，Spraying is self-walking.，Safe, easy, clean and convenient construction，Primer is not required，Save working procedures, improve efficiency and reduce cost。AboutCracking problemHot-melt coatings have poor weather resistance，Brittle at low temperatures，Poor flexibility，When the temperature difference between day and night is large，Rapidly cracking、Aging。This will not only affect the beauty of the paint，But also lead to easy water seepage.、Ooze，And even flake off，Affect the service life of the marking。In contrast，QualityMMATwo-component marking with good weather resistance，Does not absorb ultraviolet rays，Not affected by outside temperature difference and thermal expansion and contraction，No aging and cracking。
▲ Hot melt crackingAbout adhesionAdhesion of hot-melt marking on cement pavement is very poor。
QualityMMATwo-component coating on asphalt pavement、And cement pavement with qualified mark，Better adhesion than hot melt，More competitive。AboutNight visibilityHot melt marking during construction or after opening for a period of time，Uneven reflection will occur.。This is due to insufficient strength of the hot melt main material，Difficult to bond glass beads firmly。When the wheel is frequently rolled，Glass beads come off easily.。Or when the road surface temperature and air temperature are high，The reticle will soften and allow the glass beads to be pressed into the reticle paint film，These will directly affect the reflective effect and reflective life.。In addition，If there is a difference in material temperature during construction，The degree of settling of the glass beads may also be inconsistent，Thereby affecting the uniformity of light reflection.。In contrast，QualityMMAThe two-component coating forms a compact paint film surface through a chemical crosslinking reaction，So that that glass bead are firmly bonded，So that that reticle（Rain）Reflective light lasts longer at night and on wet surfaces，Higher brightness coefficient of retroreflection。The same situation，After a period of traffic wear and tear，QualityMMATwo-component reflections are generally uniform，It will not appear the shadow of a large number of glass beads falling off like hot melting.，Affect the aesthetic effect of night vision。

Hot-melt main resin has poor strength，In order to extend the life of the marking，Only the scratch thickness or recoating times can be increased，The thickness of each scribe is generally 1.5-2mm。If the thickness exceeds the standard，It will bring hidden dangers of driving safety.。If it is controlled within the standard thickness，The marking will be very thin when it is recoated，After being cooled, the coating solidifies rapidly.，So that that glass bead cannot be firmly bonded，Cause the marking line not to reflect light。In contrast，QualityMMAThe thickness of two-component spraying each time is about 0..7mm，Construction 2-Can be directly coated with two components after 3 years，The old wire can also be directly remelted，Good qualityMMATwo-component spraying is the most ideal choice for curing construction。About deinterlacingAfter hot melt aging, it is necessary to remove the line before drawing.。Water removal line/Hazards of mechanical line removal include：And that construction cost is increase、Waste of water resources、Damages the road surface and is irreversible、High recycling cost of off-line garbage、Road congestion、Increase the management cost of the owner。In contrast，MMAIf the two-component spraying marking line needs to be changed，Can be usedMMATwo-component alteration paint is directly sprayed and covered，High efficiency and long service life，And that pavement is not damage。
▲ Water line removal causes great damage to the pavement.，Waste of water resources
▲ The part of the pavement to be rerouted，Two-component covering spray can be used，High efficiency and no damage to the pavement
About low-carbon environmental protectionHot melt base oilVOCExceed the standard，Liquefied gas combustion releases carbon dioxide to pollute the environment，Dust from paint and wire removal also pollutes the environment，Not conducive to energy conservation and emission reduction。Frequent marking and removal of hot-melt markings requires road closure，Easy to cause traffic jam，Fuel consumption，Air pollution caused by automobile exhaust。In contrast，QualityMMATwo-component does not contain any harmful substances，The coating is nearly 100%High solid content，There is basically no volatilization，Green and environmental protection，In line with the country“Double carbon target” Policy 。QualityMMADurable reflective performance of two-component coatings is particularly excellent in the absence of street lamps or in the environment with insufficient street lamp light.，The road edge definition can be significantly improved.。So that that numb of the street lamps can be properly reduce and the brightness of the street lamps can be adjusted to be low，And consider turning off street lights after midnight.，As a result, a great deal of electrical energy can be saved。At the same time, it can also reduce spikes.、Outline mark、Installation of kerb light strips and a large number of electroluminescent facilities，Reduce the burden of the country and the government，Save money。
About shoveling snowThe hot-melt marking will fall off when shoveling snow.。In contrast，QualityMMAStrong adhesion of two-component marking，Not affected by snow shoveling and snow-melting agent。
About the life of the reticleHot-melt marking is easy to become soft and brittle under the influence of temperature.，Not wear resistant。Especially in multiple Vehicles、Ramp、And on roads with heavy traffic.，Wear and tear is fast，The life is shortened。In contrast，QualityMMATwo-component marking is harder than cement，In normal road conditions，Under the condition that the paint dosage is up to the standard，Wear life can even be as long as 5-10 years。
About stain resistanceHot melt markings contain plasticizers，Plasticizer will migrate.，Make the surface of the reticle sticky，It is easy to get dust。Especially in the south, the temperature is high.，Marking has poor stain resistance。In contrast，QualityMMAThe two-component coating forms a dense paint film after curing，It can effectively prevent the penetration of pollutants.，And that coat is not affected by the air temperature.，The surface will not become sticky.，Does not bind silt and dust。And，Through the rain and snow.、After flushing by Sprinkler or high pressure water gun，The marking will be as bright as new.。
About anti-skidHot-melt marking anti-skid particles are not firmly bonded and easy to fall off，The anti-slip effect is poor。In contrast，QualityMMAThe two-component anti-slip marking can be firmly attached to the anti-slip particles.，After half a year, the anti-skid value can still be greater than 55.BPN，Long slip-stop life，In particular, the zebra crossing has good anti-skid effect.，It can better reduce accidents.。

Three winsTwo-component total solutionStrong international competitivenessLook at the world，Northern Europe、 Canada 、The two-component labeling system is widely used in cold climates such as the United States.。But compared to other materials,，MMATwo-component pavement marking coatings and equipment are generally considered to be very expensive。 In addition，This advanced marking method requires engineers with more than ten years of experience to carry out the construction.。In terms of equipment， Denmark Borum、GermanyHofmannThe price of the equipment is 100-More than 2 million。These specially designed equipment due to curing agents significantly increase the equipment cost of road marking works.。Because the structure of the equipment is very complex.，Later maintenance costs are high.。Before and after sales，Need to maintain long-term technical communication，All of the above have limited the popularity and application of this advanced labeling method.。
