History of Plastics Industry

History of Plastics Industry

The first step in the plastics industry, was conducted by a person who tried to stop Hykat provide material instead of ivory. Hard material such as ivory, precious and so rare that many applications. He was able to cellulose nitrate (which they called nitrocellulose) ...

Characteristics of plastic material

An important characteristic of plastic materials in the industry, processing or Processible of it. If a substance can be melted or dissolved, or it can be used in industry, the industrial use. Because it's not unmanageable material.

Features cellulose and cellulose nitrate

Cellulose is not soluble and will not melt and decompose before melting. The process is not allowed. But both soluble cellulose nitrate and to melt. Hold the Hykat, cellulose nitrate, cellulose processing transformed into an integral process.

Characteristics of cellulose acetate

Cellulose nitrate is criticism. The effort to replace a plastic other than it began. Miles acetate produced in 1908, which also has the advantage of nitrocellulose and working with it is easier and less dangerous.

The first synthetic plastic

The first synthetic plastic, phenol-formaldehyde resin was trying to build a fully synthetic polymeric materials, in 1907, succeeded Leo Blknd of phenol with formaldehyde condensation, which later became known as phenol formaldehyde Balkyt (the final product) was called, produce. Both acidic and alkaline environments, this resin is available.

 

Fnvplast

The condensation of phenol with formaldehyde, phenol-formaldehyde resin in acidic or Fnvplast or produced. Industry is working with its maximum at 8.5 PH and PH course of the game to create this environment, NH3 or NaOH is added. For this the carpenter's glue is achieved, at the end of the molecule, should be the OH group. The attachment will be more OH groups. So for better glue, you must take additional formaldehyde. The glue that is free of formaldehyde.

AMINTOPLAST

The urea or melamine with formaldehyde plastics of condensation obtained in acidic or basic environment. The reaction temperature should be between 60 and 80 degrees Celsius. Phenol-formaldehyde glue because Bdbvyy in the market. But this tape, available in the market. Melamine or 8, 4, 6-tri-amino-1, 3, 5] can be more azide with formaldehyde in acidic or a condensation reaction carried out in terms of regulation and response, creating a one-dimensional polymer.

If 40-30% of the added calcium carbonate, into an ashtray and late flammable materials that the price drop will kill supernatural. However, the mechanical strength increases.

Thermoplastic

Polymers are under pressure, deformation, and after removal of the external force, the deformation continues and remains. In other words, are the property Plastysyty. The polymers in the heat as the temperature increases gradually soften and become a solid physical state. The nature of the use of these polymers or creates guarantees. If the thermoplastic powder or small rings are heat, soften and melt Vsykvz first, and if they die, we die to take shape.
