Tory RI 1.7 glass beads keep road marking reflective

 

The refractive index is the ratio of the light speed in a vacuum to the light speed in the medium. It is mainly used to describe the material's ability to refract light.

The material with higher refractive index, the ability to refract incident light is stronger.


In China, the standard of refractive glass beads for pavement GB/T24722-2009, according to the refractive index of glass beads, glass beads can be divided into three types: low refractive index glass beads, medium refractive index glass beads, and high refractive index glass beads, the refractive index (RI) is 1.50≤RI <1.70, 1.70≤RI <1.90, and RI≥1.90.


1.5 Refractive index glass beads: It is mainly made by crushing, sieving and melting recycled glass, the main component is silica.


1.7 Refractive Index Glass Beads: It adopt a matching method, first melting 1.7 refractive index glass, then furnacing glass beads.The main component is titanium dioxide, with a density of ≥3.0.The technical requirements and melting process are complicated, but the maximum retro reflective of 1.7 index glass beads can reach more than 1000mcd, and it has a good reflectivity in rainy night condition.Drop on the 1.7 beads on road without paint, it can reach about 200mcd.Particle size range: 0.212 ~ 2.0mm.

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.

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. A customer asked how to make a diaper , and we showed him the whole production process. He was very pleased to say that your process for making diapers is the same as that of HCH and Xing Shi. The workshop is very clean, good quality, low price, very cost-effective. Now let's take a look ...

Brass ball valve making machine,Automatic brass ball making machine

  A Ball Valve is a quarter turn valve which can be opened or closed by applying pressure on the hollow and pivoting ball inserted into void opening. It is usually used as a switch that can control and direct the flow of fluids (including air, water, gas, oil etc.). When the hole in the ball is aligned to the flow, it is open and closed when it is perpendicular. Automatic brass ball machine  carries out the automatic test of the brass ball valve with manual loading of the components. More details, pls contact  Nicole office@desutrading.com
