It is very important to carry out daily inspection and replacement of various accessories in the garbage truck. It can improve the working efficiency of the garbage truck and prolong its service life, and it can prevent some risks from occurring. For maintenance-based, as the case of repairs; seven maintenance, three points to repair these new ideas have gradually been accepted by the majority of garbage truck owners. Here's to tell everyone about the daily inspection of garbage trucks .

The first thing to do is to check all the luminaires and warning devices, including reversing alarms and filling cues, and repair or replace them in time if a fault is found. The second is to regularly check the link of the garbage truck wiring harness, as long as the method is to visually check, to see if the garbage truck harness has cracking, loose, poor contact.

It is necessary to regularly check the tire pressure of the garbage truck and the wear of the tread pattern. If the nuts are loose, the inspection cycle is preferably performed once a week. The inspection method is visual inspection, and then let the garbage truck run up again to see if there is any deviation or drifting. If there is any of the above conditions, it must not be used recklessly or if there is a safety incident during the driving process. At this time, we must check the four-wheel-bit position of the garbage truck and the dynamic balance check. Of course, this must be done after the sale of the garbage truck manufacturer. After passing the straight road test, it can continue to travel on the road. Also check the condition of the oil and brake oil of the garbage truck once a week, and add and replace them in case of any shortage.

Always pay particular note is that garbage truck brake system, garbage truck brake is generated by friction braking effect. After a long period of use, the brake system of the garbage truck will be mixed with water and sediment and other impurities, resulting in a sharp decline in friction coefficient, so the braking effect will be reduced. During the course of driving and there may be a safety accident, resulting in the loss of life and property.

The above is a brief introduction to the routine inspection of garbage trucks. In daily life, we must strictly perform the inspection and maintenance of the parts mentioned in the article so that no problems can arise during the driving process. (Wen/Jun Xun)

PVDF Sheet Rod

HONYFLUO®PVDF, polyvinylidene fluoride, is a versatile fluoropolymer which is both strong and tough as reflected by its tensile properties and impact strengths. PVDF has excellent resistances to creep and fatigue. In thin sections, such as films, filament, and tubing, PVDF components are flexible and transparent. PVDF resin is produced by the Arkema and Soltex companies and sold under their respective tradenames of Kynar and Solef.

Where load bearing is important, PVDF fluoropolymers are rigid and resistant to creep under mechanical stress and load. Because PVDF is stable to sunlight, and other sources of ultraviolet radiation, it is widely used as base resins for long-lasting exterior coatings. An additional advantage over other fluoroplastics is that PVDF can be welded into tanks for acid and corrosive chemical processing in elevated temperature environments.

Special Properties of PVDF polyvinylidene fluoride


1. Its Anti degeneration is also one of the optimal fluoride resins.

2. It has excellent insulation properties, dielectric constant (60~ 106Hz) reaches 6.0~8.0.
3. Its radiation-resistant properties are more prominent, radiated by 3x 108 lats r-ray irradiation.
4. It has a high tensile strength, good impact strength and toughness, high hardness and abrasion resistance.
5.Moreover, its water absorption is only 0.03% in 80C; Its chlorine penetrability is the smallest among fluorine resins.
6. The PVDF has the excellent physical properties. The relative density of polyvinylidene fluoride is 1.75~1.78. Long-term use temperature is -40~+125℃.
7. The mechanical strength of PVDF is the most superior among Fluorine resin, and under certain temperature and pressure it can still maintain a good intensity.
8. PVDF has the characteristics of prominent anti-aging of UV and weather aging resistance, its products even stay outdoor 10 or 20 years, they will not be friable or split.

9. PVDF has a good chemical stability. It will not be corrupted by acid, alkali, strong oxidizing agent and halogen at room temperature; it will not be affect by ordinary organic solvents; it can only be swelling or partly dissolved by a handful of chemicals such as fuming sulfuric acid, alkali, ketones and ether; it can be dissolved into a colloidal solution by strong polar organic solvents such as dimethyI acetamide and Dimethyl Sulfoxide (DMSO).
