Seven thirty-seven in the morning of August 2nd, at a time when the factory started or shift time, metal products, a Taiwan funded background is located in Jiangsu Kunshan Development Zone, the serious explosion accident, until 2 pm the same day, therefore has caused 65 workers were killed to death, more than 120 workers were injured. Ink coolie on the mast! In addition to mast of what we can do?

If someone asked, what does this have to do with our non party, the ink cooliehere solemn refuted: why it doesn't matter? Graduate division of labor in the market society, you don't travel drive, more and more Chinese families with a car.So, you know, aluminum alloy wheels on your cars, it is by what we see in thenews today. These victims compatriots with blood and sweat in return!

To remedy the situation, not to say! Ink coolie will organize the factory dust explosion prevention in the popular science knowledge sharing, and combining the Xin Zhi robotic company business, introduces the application of industrialrobot in the polishing workshop. Haven't arrived on the scene to rescue or "chaos" is ashamed of, that at least the dissemination of information and knowledge valuable, don't let our soul with the body as numbness!

[parties enterprise accident polishing workshop business introduction]

The scene of the accident, polishing workshop of aluminium alloy wheel, this workshop is for our daily life indispensable important travel car parts processing -- aluminum alloy wheel hub polishing -- aluminum alloy wheel assembling cars in front of the middle of a process - in order to make the surface smooth, brighthub.

Characteristics of the aluminum alloy wheel hub with its beautiful appearance,safe and comfortable and has won more and more private car owners favor. Now,new models of almost all uses the aluminum alloy hub, and many owners of a friend will also originally used car hub for aluminum alloy wheel hub.

Cast aluminum alloy wheel hub polishing, generally with wool polishing wheel orpolishing machine polishing wheel is driven to rotate the gauze, add polishing waxafter repeated friction on the hub surface, so that the workpiece surface roughness is reduced, to obtain bright, smooth surface. Polishing machine is divided into manual and semi-automatic, fully automatic several levels. Manual polishing is the artificial crawl portable polishing machine for active polishing on the surface of the workpiece; semi automatic polishing is constructed using special clamping tool workpiece into polishing machine polishing polishingentrance large passive fixation; automatic polishing is used without direct manual operation mode by the machine finish on the workpiece (such as currently used abroad robot polishing system: robotic polishing machine on the surface of the workpiece for active polishing operations).

In Chinese many manufacturing enterprises, because the control technology andequipment level, and guide a few years cheap labor market, many enterprisesgive priority to the use of artificial participation in semi automatic or manualpolishing mode. According to the times so that the number of casualties, the factory workshop is likely to use manual polishing artificial way -- is divided into several groups for the finish work in the same workshop, each armed with aportable polishing machine for polishing on aluminum alloy wheel, polishing wax,waxing hub handling are artificial complete.

Polishing operations site is process very harsh manufacturing environment,because the friction of polishing wheel and workpiece, will produce a dense dustparticles suspended in the workshop, in the field of ventilation and protection measures are not good, if many workers start polishing operation, the situationcan be described as "severe dust weather", pay attention to! The floatingparticles are aluminum magnesium alloy and industrial wax and metal ions,compounds, toxic gas. In addition, fatigue and other factors of high strengthfriction noise, many polishing machine work together to generate continuous highintensity physical labor is brought, was much more difficult to bear.

In Kunshan the slightest acquaintance all know, is a county-level city under the jurisdiction of Suzhou adjacent to Shanghai's rapid development in recent years,the basic dependence to fellow Taiwanese investment. Taiwan enterprises to invest in factories in Kunshan, are settle on the land and policy, cheap cheap labor, the vast mainland market resources, while the investment factory ismanufacturing enterprise with highly labor-intensive. At the same time, dealt withthe Taiwanese people know, the merchant of Taiwan is notoriously stingy, in the mainland legal system and market supervision is not perfect today, generallythere are many sweatshops are not the one or two slogans and speech can denyit.

On the enterprise and polishing business introduction to pass by, friends should not be treated as seditious speech described above, we should objectivelyunderstand and recognize the fact that the reality of cleaning, but also to find the improved method and action. The large labor compatriots living environment,have to rely on our own efforts to improve!

The characteristics of dust explosion hazards [plant]

Factory 1 dust explosion characteristics:

(1) multiple explosions is the bigger characteristic of dust explosion.

Dust industrial production is the certain scale, and in time and space wereconcentrated. The first blast, the deposition in the equipment or the ground dustblown up, the center of the explosion area in a short time after the explosion will form internal negative pressure, fresh air around it to fill in from outside to inside,and dust mixed up, triggering two explosions. When the two explosion, dust concentration will be higher.

(2) the minimum ignition energy higher dust explosion required, generally more than dozens of mj. The factory production, often accompanied by electricity, fire and other factors, and subject to the conditions of factory workshop, high dustcart
