Cleanroom
furniture or simply known as the cleanroom is a laboratory facility normally
used as a part of scientific research or specialised industrial production
including the production of microprocessors or pharmaceutical items. They are
designed to keep up the extremely low level of particulates
like vaporised particles, airborne organisms or dust. They characteristically
have a cleanliness level ascertained by the number of particles per cubic meter
at a preset molecule measure. The milieu outdoor air in a mainstream urban area
holds 35,000,000 particles for each cubic meter and 0.5 μm in size.
AN OUTLINE
Cleanrooms can
be very big. Entire production facilities can be restricted within a cleanroom
with a factory floor covering thousands of square meters. They are utilized
majorly in semiconductor manufacturing, OLED, LCD and LED manufacturing,
rechargeable battery, solar panel, the life sciences, biotechnology and other
various fields that are extremely vulnerable to environmental contamination.
There are also adjustable cleanrooms.
The air that
enters the cleanroom from outside is pass through a filter to eliminate dust,
and the air inside is continuously spread through HEPA or High-efficiency
particulate air filters to remove contaminants that are generated internally.
Staffs make
their way in and leave via airlocks at times including an air shower stage and
put on protective clothing such as coveralls, boots, gloves, face masks and
hoods. The equipment inside the cleanroom is designed to make minimal air
blemish. Only special buckets and mops are used. The cleanroom
furniture is planned to give off a minimum of particles and is very
easy to clean.
Common
materials like pencils, paper and fabric made out of natural fibres are often
eliminated and some alternatives are used. Cleanrooms are not disinfected only
airborne particles are inhibited. Particle levels are generally tested using a
particle counter and microorganisms are detected and counted via environmental
monitoring procedures. Polymer tools that are used in cleanrooms and need to be
determined very carefully to make sure they are chemically compatible with the
processing fluids of the cleanroom also ensure to keep a low level of particle
generation.
Few cleanrooms
are maintained at a positive pressure, in case any leaks occur, the air leaks
out of the chamber as an alternative to the unfiltered air coming in. There are
few other cleanrooms with HVAC systems that control the humidity to such a low
level that extra tool like air ionizers are needed to prevent the problem of
electrostatic discharge.
WHAT IS THE PURPOSE OF CLEANROOM FURNITURE?
Every Cleanroom
Equipment intends to maintain an environment by ceiling the presence of
sub-micron particles and adjusting insufficient environmental conditions. The
intensity to which the environment is managed is what parts one cleanroom from
another. For example, a cleanroom for class 10 has 10 particles of size 0.5
microns per cubic foot of air, but in case of a class of 100,000 the cleanroom
will have 100,000 particles in size of 0.5 microns per cubic foot of air.
WHY DO WE NEED CLEANROOM?
The medical,
aerospace, pharmaceutical, semiconductor, high-tech, electronics and many other
industries depend on the technology of cleanrooms. As products like the circuit
boards of the cell phone become smaller, the probability of blot in production
grows higher. In the case of pharmaceutical companies, contaminant-free, clean
and safe products are very important to producing and distributing the feasible
product.
