parts to be cleaned
Definition:Parts to be cleaned are (metallic) objects that are processed in (thermal) cleaning systems.
plastic
Definition:Plastic is defined as an organic polymeric solid, which is synthetically or half synthetically produced from monomers of organic molecules or biopolymers. There are three groups: Thermosets, Thermoplastics and Elastomers.
Polyacrylate
Definition:Polyacrylates are polymers made from the esters of acrylates. This includes plastics which, among others, are included in paints and used as dispersing agents in adhesives.
Polyamide
Definition:Polyamides (PA) are linear polymers with regularly repeating, hydrolytically separable amide bonds along the main chain. Polyamides are often used as construction materials because of their outstanding strength and toughness.
Polyester
Definition:Most polyesters are synthetic polymers (plastics) with ester functions, –[‚–CO‚–O‚–]‚– in their main chains, like e.g. the commonly used polycarbonate (PC) and above all the thermoplastic poly-ethylene-terephthalate (PET).
Polyether ketone
Definition:Polyether ketones (PEK) are polymers that have alternating ketone and ether functions in their backbone. The resulting very rigid backbone gives the plastic very high temperature resistance. PEEK is used most commonly.
Polyimide
Definition:Polyimides (PI) are plastics that have the imide group as their most important structural feature. Among other things they are used for especially thin but very stable lacquer insulation of elect. wires e.g. for weight reduction in aerospace technology.
polymer
Definition:A polymer is a chemical bond of chains or branched molecules, which are made of the same or similar units, of which the so-called repeating units are comprised.
Polyolefin
Definition:Polyolefins is a general term for polymers made from alkenes such as ethyls, propylene, 1-butene or isobutene by polymerization, like e.g. polyethylene and polypropylene.
Polystyrene
Definition:Polystyrene (PS) is a transparent, white foamed, amorphos or partially crystaline thermoplastic. Polystyrene is used either as a thermoplastically processed material or as a foam material ("styrofoam").
Polysulfide
Definition:Organic polysulfides are organic compounds, which have a sulfur as a functional group. They have a great technical importance for the manufacture of sealants, in particular the manufacture of insulation glass.
Polyurethane
Definition:Polyurethanes (PU, PUR) are plastics or synthetic resins that result from poly addition reactions of di-alcohols (diols) and polyols with poly-isocyanates. Depending on the process they can be hard and stiff or soft and elastic.
PTFE
Definition:Poly-tetra-fluoroethylene (PTFE, also Polytetrafluoroethene) is an un-branched, linearly structured, partially crystalline polymer (thermoplast) made of fluorine and carbon (also known as "Teflon" or "Gore-Tex").
PVC
Definition:Polyvinyl chloride is an amorphous thermoplastic. PVC is hard and brittle and gets soft only by adding plasticizers and stabilizers, ans thus mouldable and suitable for technical applications.
pyrolysis
Definition:Pyrolysis or pyrolytic degradation is a thermo-chemical separation of organic compounds, by which through high temperature (200‚–900 °C) a breakdown of the bond within larger molecules is forced to make them smaller.
resin
Definition:Resins are liquid to solid, organic, water-insoluble substances. Natural resins can be found particularly in trees, synthetic resins are produced synthetically. Resins are among others used for the production of paints, soaps and drugs.
spin pack
Definition:A spin pack usually consists of a housing with material feed and assembly ring, multiple filters, distributer and perforated disc as well as a spinneret through which the polymer melt is extruded for the production of textile fibers.
spinneret
Definition:A spinneret is a device, in which molten polymer is extruded through capillaries ("spinning") to produce textile fibers. Depending on the capillary type solid or hollow fibers can be formed.
static mixer
Definition:A static mixer consists of fixed flow control elements in a pipe and serves to mix fluids, by which the flow movement alone creates the mixing effect.
thermal cleaning
Definition:During the thermal cleaning a thermal oxidation phase follows a pyrolysis phase at approx. 430 °C, with which any remaining carbon is completely removed.
thermoplastic
Definition:Thermoplastics, also called plastomers, are plastics that can be formed in specific temperature ranges (thermo-plastic). This process is reversible, so long as the material is not thermally degraded by overheating.
