The heavy responsibility of the city's "clear bowel" falls on the body of the plumbing vehicle. It has indelible credit for the construction of cities throughout the country. What precautions should be taken when using a plumbing vehicle?

The first is how to open a pipeline to clear the car? Many people say that it is not driving. What kind of car is not open? In fact, in addition to the different categories of driving licenses we know, the drivers need to pay more attention when driving a car to open the pipeline. More attention must be paid to operating this professional vehicle.

Due to the fact that there are many complicated terrain ramps in the city and the vehicles are dense, the driver must not only pay attention when the pipeline is drove through the urban turntable, but also has the ability to “see the four parties”. Drivers need to make full use of rear-view mirrors, not only to take into account the surrounding environment. When driving out of the turntable into the meandering lane, if there is a vehicle that enters the turntable at the right rear, the driver should focus on the right rearview mirror. If you are in a bustling or narrow street, you need to reduce the speed and drive slowly.

In addition to the dredging of vehicles on the road, there are other considerations for opening the vehicle. When the staff begins to clear the pavement pipeline, it is necessary to set up a safety warning sign, and to make adequate isolation facilities. Before operation, it is necessary to confirm that the oil, water, and gas valves are all in the open state, and the high-pressure three-way connection is in a circulating state. In addition, before clearing the pipeline, it is necessary to confirm that the end of the high-pressure hose nozzle enters into the pipeline by more than 300 mm. The reason for this is to prevent the nozzle from rebounding and hurting people and protect the workers and roadside pedestrians. During the cleaning process, keep open the rear doors of the rear cabin of the cab, so as to maintain good ventilation and avoid excessive heating.

Pipeline dredge vehicles also need to be regularly cleaned every day, regularly check the cleaning filter device and replace the lubricating oil to keep the vehicle in good condition. Only by doing these precautions on a regular basis can we better complete the “clean bowel” task of the city.

PC Plastic Rod

PC plastic,full name Polycarbonate.

PC plastic is a kind of excellent comprehensive performance engineering plastics.It has excellent physical, mechanical, electrical, and thermal properties,so it's known as the "king of the transparent plastic'

Classification:

Anti - static PC SHEET, conductive PC SHEET,fireproof PC SHEET,PC fiber - resistant, PC GF SHEET, PC+ABS SHEET,anti-ultraviolet ray resistance PC, food grade PC, anti - chemical PC.

Advantages:

1,Light weight

2,Impact resistance

3,Excellent physical, mechanical, electrical and thermal properties

4,Ultraviolet resistance

Disadvantages:

Polycarbonate is not resistant to ultraviolet light, no resistance to alkali, resistance to hydrolysis stability is not high, is the main performance defect is sensitive to the gap, resistance to organic chemistry, scratch resistance is poorer, long-term exposure to ultraviolet light yellow, are vulnerable to the erosion of some organic solvents.

Applications:

1. Dust-free room spacer

2. Equipment shield and test fixtures;

3. Commercial Building Lighting;

4. Soundproof walls;

5. Greenhouse;

6. Components for medical and pharmaceutical devices;

7. Face shields;

8. Skylights, etc

Modified use:

The purpose of the modified PC Plastic is to toughen, improve the processing performance, reduce the residual deformation, and increase the flame retardancy, etc.

PC/ABS can improve bending modulus, heat resistance and plating performance.

PC/PET and PBT can improve drug resistance and solvent resistance.

PC/PMMA added plexiglass to enhance the appearance of pearlescent color.

PC/PA and HIPS can improve impact toughness and surface finish.

PC/HDPE can improve water resistance, aging resistance, weather resistance and LDPE.

The PC Plastic USES fiberglass or carbon fiber to enhance modification and improve mechanical strength.

The flame retardant grade PC Plastic can be made with bromine flame retardant and antimony trioxide.

Other and polysulfone, aromatic polycarbonate, polyvinyl formaldehyde, polypropylene, polystyrene can be modified to achieve the balance between economy and performance.

Combustion characteristics:

Combustion condition: easy, softening foaming

Flame status: small amount of black smoke

After the fire: out of the fire

Bouquet: no special taste

Specification: the thickness of PC Plastic sheet material can be produced from 0.3mm to 1.9mm, the normal width is 600mm, the width cannot exceed 1200mm, the length is not limited.
The thickness of plate can be produced from 2mm to 180mm, the usual specification of 2-10mm is 1000mm* 2000mm, and the commonly used specification of 10-180mm is 600*1200 mm. PC Plastic sheet can also be customized according to requirements, and the width cannot exceed 1200mm, and the length is not limited.and The diameter of the PC Plastic rod can be produced from 2mm to 250mm, the length is 1 meter, and it can be ordered to be more than 3 meters in length.

Color: Black and clear, can also be made another color, and the color order is 500KG.

Modified varieties:PC Plastic can be added to the Glass Fiber, copper powder, and molybdenum disulfide enhancement plate according to customer's requirements.
Add antistatic agent to the permanent plate, the volume resistance value of 10 to the 6 to 9 power.
Add flame retardant to the flame retardant board from UL 94v-0 to HB combustion grade, and other modification requirements are required to customize various additional properties according to the actual use of the customer.

Product certification: most environmental certification reports and safety reports for raw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
