The chemical industry is an industry involved in the
production of chemicals. This industry includes the production of
petrochemicals, agrochemicals, pharmaceuticals, polymers, paints, and oleo
chemicals. The chemical industry as a whole is involved in chemical
processes which include chemical reactions to form new substances,
separations based on properties such as solubility or ionic charge, and
distillations, besides transformations by heating and other methods. It is
involved in the processing of raw materials obtained by mining, agriculture
among other supply sources, into materials, substances, chemical compounds
that are finished products or are used in other industries.
Rubber Products in chemical industry
There are wide varieties of rubber products manufactured for a full range
of Chemical Metering and Dispensing Equipment Applications. Besides the
rubber products, rubber is itself used in various chemical processes. In
practically all chemical plants, there are some process or reaction in which
a corrosive reagent is used or produced. Hard rubber of suitable compound is
chemically inert to a high degree and is used in connection with a great
many corrosive materials. Essentially, hard rubber is rubber compounded with
a relatively high percentage of sulfur. Many laboratory tests have been made
in which hard rubber has been mixed in various chemicals for long periods of
time. Various chemical acids like sulfuric acid , nitric acid, hydrochloric
acid, acetic, hydrofluoric, phosphoric acids, sodium and potassium salts,
zinc chloride, calcium chloride, and many others, as well as corrosive
gases, such as chlorine, hydrochloric acid gas, etc. use hard rubber in
their chemical processing. Hard rubber is also attacked by most rubber
solvents, such as benzene, carbon disulfide, and chloroform, which soften
and swell the rubber.
Rubber products are used for numerous applications in the chemical
industry such as:
- Urethane Foam Dispensing
- Paint Spraying
- Protective Garment
- Adhesive Dispensing
- Glycol Cooling
- Crack Filling
- Vacuum Filtration
- Vacuum Stripping
- Drying of Various Materials
- Chemical Transfer etc.
Rubber products used in chemical industry are as follows:
