How does people use cellulose?

Answer 1

Cellulose is the major constituent of paper and cardboard and of textiles made from cotton, linen, and other plant fibers. Cellulose can be converted into cellophane, a thin transparent film, and into rayon, an important fiber that has been used for textiles since the beginning of the 20th century. Both cellophane and rayon are known as "regenerated cellulose fibers"; they are identical to cellulose in chemical structure and are usually made from viscose, a viscous solution made from cellulose. A more recent and environmentally friendly method to produce rayon is the Lyocell process. Cellulose is the raw material in the manufacture of nitrocellulose (cellulose nitrate) which was historically used in smokeless gunpowder and as the base material for celluloid used for photographic and movie films until the mid 1930s. Cellulose is used to make water-soluble adhesives and binders such as methyl cellulose and carboxymethyl cellulose which are used in wallpaper paste. Microcrystalline cellulose (E460i) and powdered cellulose (E460ii) are used as inactive fillers in tablets[7] and as thickeners and stabilizers in processed foods. Cellulose is used in the laboratory as the stationary phase for thin layer chromatography. Cellulose fibers are also used in liquid filtration, sometimes in combination with diatomaceous earth or other filtration media, to create a filter bed of inert material. Cellulose is further used to make hydrophilic and highly absorbent sponges. Cellulose insulation made from recycled newsprint is becoming popular as an environmentally preferable material for building insulation. The major combustible component of non-food energy crops is cellulose, with lignin second. Non-food energy crops are more efficient than edible energy crops (which have a large starch component), but still compete with food crops for agricultural land and water resources.[8] Typical non-food energy crops include industrial hemp, switchgrass, Miscanthus, Salix (willow), and Populus(poplar) species. Some bacteria can convert cellulose into ethanol which can then be used as a fuel; see cellulosic ethanol.

Answer 2

When processed with various other minerals, Cellulose powder can be used in the coating of consumable SMAW (arc) welding electrodes. When the arc is struck the cellulose coating acts as flux, vapourising at the same rate as the metal electrode melts, forming an inert gas shield around the molten metal puddle, which prevents oxidisation of the metal and helps maintain the arc. The Cellulose (no longer cellulose) then forms a crust, called a slag deposit, on the surface of the weld bead, which can be chipped away to reveal the bead itself.

Answer 3

Cellulose is found in a lot of the things we use on a daily basis. Some of these things include paper products, fibers, consumables, and in energy crops.
