Clean Room Technology Then And Now

Posted on by blogger

The principle of Clean room design starts from almost 150 years ago when these units were used for bacterial control in hospitals. Today, clean rooms have completed a long way and developed to the modern technology. In earlier day, these clean rooms were designed for fulfilling the requirement of clean environment for industrial manufacturing during 1950s and the same clean rooms are also used for variety of applications in many industries.

A clean room is defined as a place that provides attentively controlled environment that has a low level of environmental pollutants such as airborne microbes, dust, chemical vapors, and aerosol particles. When the air entered in a clean room it is filtered and then continuously circulated through high efficiency particulate air (HEPA) or ultra-low particulate air (ULPA) filters. These filters are used to remove internally generated contaminants. The persons, who work inside the clean room, wear protective clothing while enter and exit through airlocks, while equipment and furniture inside the clean room is specially designed to produce minimal particles.

Today, more than 30 different industry segments utilize clean rooms including semiconductor and other electronic components, pharmaceutical, and biotechnology industries.

Modern clean rooms were developed during the Second World War to improve the quality and reliability of instrumentation used in manufacturing guns, tanks and aircraft. During this time, HEPA filters were also developed to contain the dangerous radioactive, microbial or chemical contaminants that resulted from experiments into nuclear fission, as well as research into chemical and biological warfare.

On the other hand, clean rooms for manufacturing and military purposes were being developed; the importance of ventilation for contamination control in hospitals was being realized. The use of ventilation in a medical setting gradually became standard practice during this time.

The concept of laminar flow was introduced during 1950s and 1960s, when NASAs space travel program was initiated. This marked a turning point in clean room technology and from this time, the evolution of clean rooms gained momentum.

In the late 1950s, the Sandia Corporation (which later became Sandia National Laboratories) began investigating the excessive contamination levels found in clean rooms. Researchers found that clean rooms were being operated at the upper practical limits of cleanliness levels and identified a need to develop alternative clean room designs.

In 1961, Professor Sir John Charnley and Hugh Howorth, showed a tremendous improvement in unidirectional airflow by creating a downward flow of air from a much smaller area of the ceiling, directly over the operating table.

Also in 1961, the first standard written for clean rooms, known as Technical Manual TO 00-25-203, was published by the United States Air Force. This standard considered clean room design and airborne particle standards, as well as procedures for entry, clothing and cleaning.

In 1962, Patent No. 3158457 for the laminar flow room was issued. It was known as an ultra clean room.
By 1965, there have been several vertical down flow rooms were used in which the air flow ranged between 15 m (50 ft)/min and 30 m (100 ft)/min. It was during this time that the specification of 0.46 m/s air velocity and the requirement for 20 air changes an hour became the accepted standard.

By the early 1970s the principle of laminar flow had been translated from the laboratory to wide application in production and manufacturing processes.

The 1980s saw continued interest in the development of the clean room. By this stage, clean room technology had also become of particular interest to food manufacturers.

In 1987, a patent was filed for a system of partitioning the clean room to allow zones of particularly high-level cleanliness. This improved the efficiency of individual clean rooms by allowing areas to adopt different degrees of cleanliness according to the location and need.

In 1991, a patent was filed for a helmet system that can be used in a medical clean room in which the user is protected from contaminated air in the environment, while the patient is protected from contaminated air being exhausted from the users helmet. Such a device decreases the possibility of operating room personnel being contaminated with viruses carried by the patients being operated upon.
The pace of clean room technology transformation has accelerated over recent years. Since the year 2000, there have been significant advances in new clean room technology, which have helped to streamline manufacturing and research processes, while also reducing the risk of contamination. Most of the technological developments of the past decade have been directed towards the manufacture of sterile products, particularly aseptically filled products.

In 2003, Eli Lilly pioneered the development of a new system for the prevention and containment of cross contamination during the manufacture of pharmaceutical powders using a specially designed fog cart. This allows the operator to be covered by an exceptionally fine fog of water on exit from a critical area, virtually eliminating the risk of transferring dust traces beyond their proper confines.

The Future of Clean Rooms
Today, clean rooms are used in variety of applications. The presence of these units can be seen in the manufacturing of semiconductor and other electronic components, as well as in the pharmaceutical and biotechnology industries. Furthermore clean room technology has more recently been applied to micro- and Nano-system processes, and this looks certain to be an area of growth in coming years. The development of clean room technology is likely to continue to be driven by certain key factors including the increasingly technical use of exotic physical and biological phenomena, the central role of increasingly fine structures, the creation and use of materials of the highest purity, and the increasingly broad-based utilization of biotechnology. Given the scale of these challenges, clean room technology looks set to remain indispensable to production in coming years.

Impact of photography on advertising industry

Posted on by blogger

It is really hard to imagine a technology that had more impact on 20th century life than photography. It is truly the most pervasive. Photography changed the way we remember things. It offers spontaneity and has the ability to capture actual events, a slice of reality. Roland Barthes, a preeminent theorist of photography, said that photograph is the “sovereign contingency,” meaning it is dependent on something else happening.
To imagine a social world before photography, we would have to think of a world without picture IDs; without portraits of ordinary people; one without pictures as souvenirs of travel; one without celebrity pictures; one without advertising photographs; one without X-rays or views of outer space; a world without views of foreign and exotic peoples; one without pictures of sports, wars, and disasters; and one in which the great masses of people had no way to visually record the important events of their lives.
Such a world is unbelievable to us now, and we have photography to thank for all these things: visual souvenirs, portraits of common folk as well as the famous, advertising pictures that have created desire in the public and educated them about all the products the new consumer culture has on offer, medical diagnostic tools, incredible views of exotic places and even of outer space, pictures of the worlds news, and most important, pictures of the events and intimate moments of ones own life.

The technology of photography is part chemical, part optical, and dates from 1839. Soon after its simultaneous invention by William Henry Fox Talbot in England and Louis Jacques Mand Daguerre in France, photography was used to document foreign places of interest such as India, the Holy Land, and the American West. It was also used for portraits with photographs taken of kings, statesman, and theater or literary personalities.

Advertising Photography
Even as Kodak was using advertising to create a market for its cameras, films, and papers, the advertising industry itself turned increasingly to photography during the 20th century. Newspapers as well as the great number of popular magazines (especially in the pre-TV era) were the carriers of most of this print advertising.
The purpose of using high resolution images for advertising was and is to create a desire for the new consumer products available to the public, and then, of course, to sell the products. Although drawings and painted illustrations were featured predominantly in ads during the early part of the century, gradually photography took over, and by the end of the 20th century virtually all visual advertising was photographic. Today, in the 21st century, digital photography has introduced the kinds of fantastic effects impossible in straight photography, further enriching the possibilities of advertising photography and especially Indian pictures.

While half-tone reproductions of photographs had been possible since the 1880s, and magazines and newspapers constantly used them in their editorial pages, before World War I advertisers seldom did. The great shift happened in the 1920s and 1930s. By the mid-1930s photographs at least equaled hand-drawn illustrations in print advertising, and have only gained greater dominance since then.
Photography has a great impact on advertising and marketing materials and can make or break your first impression with a potential customer. You know the old saying, A picture says 1000 words? Well that has never been truer than it is today. We are all tech-heads, and we want everything this secondif we have to wait, we become irritated and move on.
Using great photography and high resolution images is a great way to get your message across quickly and say your 1000 words without actually saying any words. It immediately fascinates your audience, and a fascinated audience is more likely to read more of your message.
A concrete impact of photography has been the number of people employed in the industry, particularly after the introduction of 35mm film in the 1920s by the Kodak Company. Photography also meant new employment opportunities as photo reporters and editors, and in photographic agencies and libraries.

Short Process Of Powder Metallurgy Technology

Posted on by blogger

Technology of powder metallurgy parts near net shape powder metallurgy workers has long been one focus of the study subjects. Over the past decade, the study of new technology, new technology after another. These new technologies, the emergence of new technology to solve the short-flow low-cost powder metallurgy materials forming problems, greatly contributed to the rapid development of powder metallurgy parts. Currently, powder metallurgy parts manufacturing technology development is to increase density, reduce costs and complexity of high-precision near net shape parts mouth.
In 2000, Germany’s Fraunhofer Institute has developed one of these are known as the flow temperature and pressure of the short process of low-cost near-net shape technology. The temperature and pressure process technology-based and combines the advantages of metal injection molding technology. By improving the mobility of mixed powders, filling ability and formability, can 😯 ~ 130 , in the traditional press on the precision forming of parts with complex geometries, such as the vertical direction with a groove with the suppression of the hole and threaded hole and other parts. 2 without the need for subsequent machining. Flow temperature and pressure forming technology not only to overcome the traditional powder metallurgy forming a complex geometry in the gaps, but also avoid the high cost of metal injection molding technology is a great potential of new technology, has a very broad application prospects.
Flow temperature and pressure forming a new type of powder metallurgy parts, as near net shape technology, its main features can be summarized as follows: 1) forming parts with complex geometry flow using temperature and pressure can be directly formed with grooves perpendicular to the direction of repression, holes and screw holes and other parts, while the use of the shape of the cold manufacture of such parts is very difficult or even impossible, manganese powder the general need to complete the subsequent machining, CNC press to realize that the use of complex and precise movements , can only produce a relatively simple type of parts. Fraunhofer researchers used a special mold, the T-hole, hole, L-shaped cavity mold hole has been studied and successfully prepared a T-shaped parts. The results show that the well-mixed powder flow is sufficient to avoid cracks in the corner. Fraunhofer researchers have also used the shape with a slight taper to successfully direct the punch forming a deep blind hole parts, blind holes and wall thickness of the high rate of up to 3 to 7, the changes in wall thickness in the range of 1 ~ 3mm . Flow temperature and pressure can also be precision ground forming threaded holes. With the external thread of the bolt with a core mold after compaction, it will tighten the bolt out from the semi-finished products, and then sintering can be obtained thread. According to shrinkage by selecting the appropriate core diameter of the bolt thread can be suppressed without the required 2 machining.
2) The compacts of high density, density, temperature and pressure than the uniform flow of powder loading density as high, so after the semi-finished products by the temperature and pressure can reach very high density values. In addition to density, the powder flowability as well, forming parts and more uniform density. Or use a simple model red (no auxiliary floating red multi-axis model) can be multi-step forming of powder metallurgy parts.
3) the adaptability of materials Fraunhofer researchers conducted a variety of metal powder flow of warm compaction studies, have made a more significant results, including low alloy steel powder (Distolay AE), stainless steel 316L powder, silicon powder pure Ti powder and WC-Co hard metal powder. Flow temperature and pressure process in principle applicable to all the powder system, the only requirement is that the powder sintering must be good enough to eventually reach the required density and performance.
4) to simplify the process, reducing costs forming parts using conventional powder metallurgy method to suppress in the direction perpendicular to the grooves, cross holes and other shape, need to design very complex molds or 2 times after sintering machining to complete. Although injection molding technology in the shape of forming part of the complex and almost without any restrictions. However, due to large number of added binder, nickel powder in the heating process in part because of the influence of gravity to deform. Therefore, it often requires an additional more complicated and more expensive binder removal process, making the injection molding of high cost than conventional powder metallurgy technology, so the injection molding of parts may not be able to meet its design features to replace the conventional powder metallurgy parts to the application of injection molding technology has been somewhat restricted.
The flow temperature and pressure forming technology, either directly without the need for complex geometries 2 subsequent machining; the other hand, the flow temperature and pressure forming process, the use of a special binder and lubricant content is moderate, the configuration of the hybrid powder has a high viscosity and critical shear strength, the heating process does not occur in the deformation, which can be directly removed during sintering binder. Thus, the traditional powder forming process and injection molding process compared to current techniques for temperature and pressure forming of complex geometry parts, the only simplifies the production process, but also significantly reduces manufacturing costs.
