Powder coating is an advanced method of applying a decorative and
protective finish to a wide range of materials and products that are
used by both industries and consumers. The powder used for the process
is a mixture of finely ground particles of pigment and resin, which is
sprayed onto a surface to be coated. The charged powder particles adhere
to the electrically grounded surfaces until heated and fused into a
smooth coating in a curing oven. The result is a uniform, durable,
high-quality, and attractive finish. Powder coating is the
fastest-growing finishing technology in North America, representing over
10% of all industrial finishing applications.
How Does It Work?
Powder coating is a dry finishing process. Finely ground particles of
pigment and resin are electro statically charged and sprayed onto the
products to be coated.
The parts to be coated are electrically grounded, so that the charged
particles adhere to them until melted and fused into a solid coating in
a curing oven.
The result is an attractive, durable, high-quality finish. The powder
coating process itself offers another advantage -- it is environmentally
friendly...virtually pollution-free!
Unlike liquid paint, no solvents are used, so only negligible amounts of
VOCs are released into the air. In addition, unused or over sprayed
powder can be recovered, so any waste is minimal and can be disposed of
easily and safely.

Asthma Trigger
Asthma Trigger
Although some asthma patients "outgrow
their asthma," most do not. Some patients even wait until their senior
years to develop asthma. Common asthma triggers that affect younger
people can also affect older people. If you have asthma, you need to be
aware of situations and exposures that trigger your asthma response.
You may find that you wheeze and cough when you are exposed to a cat or
a dog. Sometimes this will appear a year or two after you have given the
furry critter a home and fallen in love with it. If your asthma is worse
at specific times of the year, it may be related to seasonal pollens.
You might also note that you have difficulty when you cut grass or pull
weeds. Dust mites and molds are common in humid environments and will
bother you when you stir them up by vacuuming the overstuffed furniture
or shaking the rug.
Triggers of asthma
Asthma symptoms can be triggered by several factors, including:
Allergens
Irritants such as tobacco smoke, strong odors
Weather changes
Viral or sinus infections
Exercise
Reflux disease (Stomach acid flowing back up the esophagus, or food
pipe)
Medications or foods
Emotional anxiety
Every person has their own triggers. If you have asthma you can minimize
your symptoms by avoiding the factors that trigger your symptoms, and by
working with your physician to develop an effective management and
treatment plan.
