Clean Room Cleaning Supplies are as varied and varied as their applications. There are tissues, sponges, mops and towels. Also grouped together will be disinfectants, wiping alcohol and acetone. Static clean room cleaning supplies include: tacky mat, tacky roller, and shoe cleaner. There is a category of supplies that falls under the equipment umbrella. For example: auto clave (sterilizer), steam cleaner and vacuum cleaner. The classic application for this cleaning agent is semiconductor manufacturing. Almost all semiconductor companies carry out their semiconductor processes in a clean room environment. The need for cleaning supplies depends on the specific environment itself.
Clean room cleaning supplies are only needed due to the spread of clean rooms everywhere. It is therefore necessary to understand and appreciate technology; at least with an image. Willis Whitfield was accredited with the invention of the modern clean room in 1960. As an employee of Sandia National Laboratories, he designed facilities based on a constant flow of filtered air. The constant flow pushes the air particles out of the facility and carries the air through a special filter. These filters are now known as High Efficiency Particulate Air filters or HEPA. This technology quickly became an integral part of semiconductor manufacturing processes worldwide and remains so today. Obviously this technology has been refined and improved over the years. One of the fundamental steps in development is classification.
Cleanroom classification has enabled semiconductor manufacturers to create facilities that fit their needs. Classification is denoted by the number of particles of a certain size in one cubic meter of space in the room. For example, ordinary room air has 1,000,000,000 particles 0.1 microns or larger per cubic meter while the ISO class 1 classification has only 10 particles 0.1 microns or larger per cubic meter.
Clean room cleaning equipment is selected based on its ability to perform the required ISO classification. For this purpose, the most important characteristic of cleanroom cleaning supplies is the non-particle generation, or, yielding of particles suitable for the existing classification. These special characteristics lead to the selection of the base materials used in the manufacture of cleaning products.
The materials used in the manufacture of cleanroom cleaning kits include a variety of materials from organic to synthetic. If we look at a particular group of cleaning products, such as wipes and sponges, we will find a well-focused list of ingredients. These include: paper, cotton, polyester, nylon, cellulose polyester blends, microfibers and more recently, molded plastics. Paper and cotton products produce the most particulates and are therefore best suited for less stringent conditions. Next are nylon, polyester and polyester blends. It is perfect for mid-range applications. For the most stringent cleaning supply requirements, products based on microfibers and molded plastics are usually preferred.
Another important characteristic of this clean room cleaning kit is its ability to absorb water and similar liquids. Typical activities that depend on this property are: cleaning up spills, removing contaminants from critical surfaces and cleaning maintenance of semiconductor process equipment. These activities are carried out on a scheduled basis, or as needed. Absorption is a function of the base material: sponge, rag, mop or towel. The least absorbent materials are paper and cotton. Also some of these products are single use only. The next most effective for absorption are products based on: a mixture of nylon, polyester and polyester. For the most demanding tasks, microfiber based products and molded plastics excel. Some of these products are even reported to be able to hold up to 600% water by weight.
