The cylinder has two types of reciprocating linear motion and reciprocating swing. The cylinders for reciprocating linear motion can be divided into four types: single acting, double acting, diaphragm type and impact cylinder. The pneumatic actuator converts the pressure energy of the compressed gas into a pneumatic actuator of mechanical energy.
1. Single-acting cylinder: There is only one piston rod at one end. The air supply from the piston side can generate air pressure. The air pressure pushes the piston to generate thrust and returns by spring or self-weight.
2. Double-acting cylinder: alternately supply air from both sides of the piston and output force in one or two directions.
3. Diaphragm cylinder: replace the piston with a diaphragm, output the force only in one direction, and reset with a spring. Its sealing performance is good, but the stroke is short.
4. Impact cylinder: This is a new type of component. It converts the pressure energy of the compressed gas into the kinetic energy of the high-speed (10-20 m/s) movement of the piston. The impact cylinder adds a middle cover with a spout and a drain. The middle cover and the piston divide the cylinder into three chambers: a gas storage chamber, a head chamber and a tail chamber. It is widely used in a variety of operations such as blanking, punching, crushing and forming.
The cylinder that reciprocates is called the swinging cylinder, and the inner chamber is divided into two by the vane, and the two chambers are alternately supplied with air, and the output shaft is oscillated, and the swing angle is less than 280°. In addition, there are rotary cylinders, gas-liquid damping cylinders and stepping cylinders.

During the process of road work, drop glass bead onto the road line painted with thermoplastic paint which is heated to certain temperature while the paint is still wet, thus to increase the reflectivity of road marking. According to the specification of Communication Industry Standard of the People`s Republic of China No. JT/T446-2001, the granulometry for drop on glass bead is shown in the table below:
Other parameters keep conformity with the type of intermix.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
