Urban roads, park paths or sidewalks are no longer monotonous black and gray. The 9233 road 3133 of the colorful 151 gives us a good mood for daily travel. The construction operation of the road surface spraying agent used to change the color of the road is extremely convenient. In addition, the spraying construction method further saves construction materials and reduces construction costs. However, the roads to be color-changed are various, and the effects exhibited by different road conditions are also different. When Jiangmen, Guangdong, uses pavement spraying agents to change the color of construction, how to deal with the construction roads.
1. Color-construction of newly-built roads. The pavement spraying agent can be used in a wide range. Asphalt roads or cement concrete pavements can use this material for color pavement treatment. For the color change treatment of these two pavements, the new road treatment is very important. The newly-built asphalt road pavement has a large gap, and the road has just been built with oil flooding. After direct spraying, it will react with a small amount of asphalt in the gap, affecting the construction effect. When the construction period is not very tight, change the color after the road is constructed and continue to open for a week; if the construction period is tight, repeatedly roll and rub the pavement when the weather is fine to improve the flooding conditions, and then change the color. The newly-built cement road may be pan-alkali and sand, and direct spraying will fall off and peel. Then spray the cement interface agent on the pavement and then use the pavement spraying agent.
2. Change the material before the original pavement exists. Another common situation is that the pavement has been changed in color before, such as the use of floor paint, but now there is fading or peeling. In this case, the road surface spraying agent can not be sprayed directly. The road surface spraying agent is an oily material. If the previous color-changing material is not cleaned and used directly, the new color-changing surface will also fall off with the original color-changing base surface, and there is no slight effect. Slowly use tools to remove the floor paint of the original pavement. If it cannot be removed, use a sander to slowly polish, but this may cause slight or heavy damage to the pavement. Strict requirements for construction operations are required to completely clean up. The road surface can be changed in color.
The service life of the pavement spraying agent is long. If it is a general landscape road, it can be up to 8 years without traffic, but the specific time is also determined by the pavement maintenance and the old condition of the original pavement. The strong adhesion of the pavement spraying agent makes The road after color change is wear-resistant and does not fade, and the color is maintained for a long time.

Brass Plated Steel Wire rope is the main substrate for the production of Diamond Wire Saw. Firstly,the artificial diamond particles are consolidated on the metal steel body to make diamond beads,and then the beads are strung on brass plated Steel Wire Rope. The special molds and equipment are used for glue injection molding, and fixing to make a strip-shaped flexible diamond cutting tool. The emergence of Diamond Wire saw mining technology in stone mines is a revolution in stone mining. The technology for stone mining has a wide adaptability, strong function, high efficiency, deep mining depth, and can be cut in various directions such as vertical, horizontal, and inclined planes, high yield, low comprehensive cost, safety and environment protection, and no noise in wire saw mining. No dust and other advantages. In today`s increasingly scarce resources and soaring oil prices, mining granite with wire saws has significant economic and social benefits.
