A humidifier is a device that increases humidity (moisture) in a single room or an entire building. In the home, point-of-use 

humidifiers are commonly used to humidify a single room, while whole-house or furnace humidifiers, which connect to a home's 

HVAC system, provide humidity to the entire house. Medical ventilators often include humidifiers for increased patient comfort. 

Large humidifiers are used in commercial, institutional, or industrial contexts, often as part of a larger HVAC system.

Low humidity may occur in hot, dry desert climates, or indoors in artificially heated spaces. In winter, especially when cold outside 

air is heated indoors, the humidity may drop as low as 10-20%. This low humidity can cause adverse health effects, by drying out 

mucous membranes such as the lining of the nose and throat, and can cause respiratory distress. The low humidity also can 

affect wooden furniture, causing shrinkage and loose joints or cracking of pieces. Books, papers, and artworks may shrink or 

warp and become brittle in very low humidity.


In addition, static electricity may become a problem in conditions of low humidity, destroying semiconductor devices and causing 

static cling of textiles, and causing dust and small particles to stick stubbornly to electrically charged surfaces.
Overuse of a humidifier can raise the relative humidity to excessive levels, promoting the growth of dust mites and mold, and can 

also cause hypersensitivity pneumonitis (humidifier lung). A relative humidity of 30% to 50% is recommended for most homes.

A properly installed and located hygrostat should be used to monitor and control humidity levels automatically, or a well-informed 

and conscientious human operator must constantly check for correct humidity levels.

What is Galvanized Steel?

There are two typical galvanizing ways to obtain a zinc coating: hot dip galvanizing and electrogalvanizing. Hot dip galvanizing is the process that steel is immersed into molten zinc bath to get a zinc coating surface. This not only helps protect steel from rust and corrosion, but also gives the steel a shiny attractive appearance. Electrogalvanizing is the process that uses electrolysis to coat the steel with zinc, which is neither cost-effective nor environmentally friendly. It is hardly to find electrogalvanized steel in our lives nowadays.


What are the advantages of Galvanized Steel?

Because of permanently and successive zinc/iron alloy layers, galvanized steel offers many benefits:

1) Corrosion Resistance: the zinc coating surface protects the base steel not only by providing barrier to corrosion elements, but also by the sacrificial nature of the coating. Galvanized steel often remains in working order with little maintenance for 40 years or more.

2) Excellent Surface Appearance

3) Formability: it can be simply bend to parts with deep drawing requirements

4) Paintability: it can be painted with different colors

5 )Weldability: it is accepted various welding practices


What are the disadvantages of Galvanized Steel?

In spite of many benefits, galvanized steel is not always an ideal choice. Galvanized steel cannot be used underground without being properly covered, which can be inconvenient for many jobs.


Where do we use Galvanized Steel?

It is primarily used in the construction industry, such as roofing, wall cladding, and support beams. It is also used in the automotive industry, due to its enhanced paintability, weldability and corrosion resistance. Moreover, it is an essential material for white goods application, such as refrigerators, air-conditioners, washers, microwaves, vending machines and audio visual systems.
