DSM Dyneema, the Ultimate "Clean" Choice for Clean Rooms

In the industry, AI chips represented by Kirin 980, Snapdragon 855, and Apple A12 all adopt 7nm process, representing the highest level of chips in the world. According to relevant information, chips with a 5nm process are also being intensively developed, and it is believed that they will be installed on mobile phones soon.

As the front end of the chip industry chain, the clean room is closely related to the rapid development of chip technology. The continuous improvement of chip technology requires that the clean room must adapt to the development speed of electronic chip technology, so the clean room of the optoelectronics industry is also constantly upgrading. The general semiconductor material clean room is required to be Class A, that is, the number of fine dust with a particle size of 0.5 microns per cubic meter is controlled below 3,500; but high-end chips such as mobile phone chips are often required to be below 1,000 per cubic meter, which is quite harsh.

Not only that, but the production process in pharmaceutical manufacturing, food production, printing and packaging industries has also improved overall, which puts forward higher requirements for clean room related equipment. Dyneema® new clean hoisting solution fiber rope hoist system (Fiber rope hoist system) came into being under the ever-increasing demand.

from tradition to modernity

What is a new type of clean room hoisting

Traditional clean room hoisting is represented by chain hoist, which is mainly composed of motor, transmission mechanism and sprocket, while new type of clean room hoisting is represented by fiber rope hoist, which is composed of motor, reducer, brake, etc. The fiber rope is unwound by the reel to drive the fetched object up and down.

Not only that, the oil and steel particles used in the chain hoist will cause serious pollution, and its application range is very limited, making it difficult to apply to high-level places such as semiconductor and pharmaceutical manufacturing. The fiber rope hoist, on the other hand, features modern design and high technology since 1999,Using Dyneema® fiber ropes instead of iron chains can be widely used in various advanced clean roomlevel scenarios such as pharmaceuticals, semiconductors, flat panels, solar photovoltaic manufacturing, microtechnology, chemistry, and aerospace.

At the same time, the reliability, power, and service life of the product are higher than the average level, and it has outstanding features such as smooth and accurate starting and braking, providing customers with Time and time again high security quality service.

From tradition to modernity, Dyneema® makes innovation possible in the clean room hoisting system.

Safety from chain to rope

A Necessary Escalation of a "Security War"

From the perspective of industrial development, every technological upgrade is accompanied by the improvement of efficiency, the reduction of cost, the replacement of materials and the improvement of safety. For clean room lifting, ensuring safety during work cannot be ignored.

From iron chains to fiber ropes, behind them is a necessary upgrade of a "safety defense war". Compared with traditional iron chains, fiber rope has three major safety advantages:

I.life safety

① Chain hoist system application

②Application of fiber rope hoist system

Due to the pollution of "oil + iron filings" produced by the chain hoist itself, the outside of the chain must be equipped with a dust cover, but the dust cover is a huge safety hazard. Because the user cannot observe whether the filler is damaged, there is a potential safety risk in daily use. Once the chain is damaged, the falling of 5 tons of items will most likely cause equipment damage and casualties, which is often unacceptable.

The fiber rope hoist system does not need a dust cover, and the user can observe the use of the fiber rope in real time. If there is a problem, he can immediately request maintenance work to ensure safe and safe use every day.

II.Ensure production safety

①Chain hoist system dust

②Fiber rope hoist system without iron filings

①Chain hoist system dust

② Fiber rope hoist system without dust

Due to the design concept, the chain hoist needs to lubricate the chain, sprockets and load wheels. But even in the lubricated state, the friction coefficient of steel is as high as 0.16, which causes the chain to still produce iron filings particles during use.

On the other hand, the chain hoist consists of a hoist brake/clutch system, which generates dust pollution due to the friction of the clutch. The role of the clean room is to control pollution to ensure production quality, and the chain hoist system obviously runs counter to this problem.

The fiber rope hoist system using Dyneema® has no such problems at all. The fiber rope hoist does not need to be lubricated, and due to the material and the friction coefficient of 0.05, Dyneema® will not produce any iron filings pollution; while the fiber hoist based on the independent overload limiter and the brake of the independent three-in-one system The system, since the friction of the clutch is removed, is also naturally "insulated" from dust pollution.

III. Excellent performance

① Chain hoist system stretching

② Fiber Rope Hoist System Tensile

① Chain Hoist System Safety

② Fiber Rope Hoist System Safety

① Chain hoist system vibration

② 纤维绳葫芦系统震动

The ring chain system has stretching phenomena throughout its service life, which can easily lead to material quality degradation and chain breakage; and the combination of chains, sprockets, load-bearing wheels, and hooks will cause the system to break. shock. It is precisely because of these design concepts that the safety factor of the chain hoist system is basically 5, and the European/Chinese level is only 1Am.

In contrast, the hoisting rope uses Dyneema® DM20 fiber, which has ultra-high creep resistance and greatly reduces the risk of fiber rope elongation under constant force. At the same time, the smooth system also prevents the fiber rope hoist from vibrating during the working process. Its safety factor is as high as 11, and the European/Chinese safety level has reached 2Am, which is far superior to the chain hoist system.

Safety is paramount. In this safety competition, the fiber rope hoist system using Dyneema® fiber rope showed its overwhelming advantages.

     The clean room intelligent crane belongs to the special crane in the subdivided field of the industry. It is mainly used in semiconductor, panel, medical, chemical, food and other industrial fields that require high equipment cleanliness. This field requires that the particulate matter produced by the crane during operation must meet the requirements of Class 1000 or even Class 100, and there are quite strict standards for the design and selection of cranes, material selection, and manufacturing, installation, and packaging.
