Long-lasting wet night road marking made by RI glass beads

Road markings provide continuous guidance information for drivers. According to Chinese national standards, rainy night marking should have retroreflective performance under dry, wet and continuous rainfall conditions, and have a good visual recognition effect on rainy nights. At present, the rainy night marking test sections set up by many provinces and cities in China are all relying on the road ceramic glass beads (AW element) to achieve rainy night reflective performance. There is no rainy night markings with reflective performance lasting more than 3 months under wet or continuous rainfall have not been found. Cntory reflective glass beads, reflective road paint material always used for rainy night marking.


In order to overcome this problem, Shandong Highway proposed a ‘long-lasting life cycle reflective road marking’. From the construction of the marking to the end of the marking life (average daily traffic flow of 80,000, more than 4 years), it maintains good reflective performance under dry, wet, and continuous rainfall conditions, which is the first in China.


The detailed information of the trial section,

1. Retroreflectivity -- Dry: 730-820mcd, Wet: 280-400mcd.

2. Paint - thermoplastic.

3. Drop on and quantity-- 600g/m2 in total, 300g HR beads of type B, 300g 1.7 index beads of Type DHR. Using two dispensers, 1st one for Type B and 2nd one for DHR.

4. Intermix and quantity -- total quantity is 30% of thermoplastic, 15% of HR beads 0.3-1.4mm, 15% of 1.7 index beads 0.3-1.4mm.

Copper rod machine melting,Copper rod upcasting machine,Copper plating line

China is short of copper, and China is also a big copper user. At present, the copper consumption of China's cable industry is about 7.5 million tons, accounting for more than 60% of China's total copper consumption, accounting for about 1 percent of the world's total copper conductor consumption, making it the largest copper user in the world. In order to solve the serious situation, the smart Chinese people try to use the machine which could meet the energy-saving requirement to produce the cooper rod. D&S copper rod making machine adopts the advanced fire refining technology to produce the¢8MM bright low-oxygen copper rod which is meet the international standards in the continuous casting line. The features of the production line are continuous casting and rolling process. There is no interruption from melting of raw material, casting process, rolling process and delivery of product, and it has high efficiency due to automatic control throughout the entire process. ...

Full-servo pull up diaper production line

With the development of  technology, the diaper machinery industry is also progressing with it. This time, XINGYUAN DNW machinery launched full servo Pants production line. This production line can be compatible with two or three pieces, and can be designed into two or three pieces and other configurations according to customers' requirements. In order to meet the needs of customers, there are many optional configuration, O cutting unit, we used is the industry's top brands, PNO, HCH also used this brand. Basic configuration is controlled by servo motor, the brand is mitsubishi. Reasonable and solid square steel frame, painted with baking paint, with second working platforms.

The workshop is very clean, good quality, low price, very cost-effective. Now let's take a look ...

Chiller installation technology

1. When selecting the position of the lifting point, first consider the best position of the air circulation, and secondly consider the direction of the structure of the storage body. 2. The gap between the chiller and the slab should be greater than the thickness of the chiller . 3. All the slings of the chiller should be tightened, and the bolts and slings should be perforated with sealant to prevent cold bridge and air leakage. 4. When the ceiling fan is too heavy, use the No. 4 or No. 5 angle iron as the lintel. The lintel should span across the other roof and wall panels to reduce the load.
