Ihe ndị bụ isi nke usoro ịgbatị plastik maka imepụta akụkụ plastik

Ngwa plastik edebanyela aha mmepe pụrụ iche n'ime afọ 50 gara aga, nke karịrị nke ngwa ahịa ndị ọzọ.

Ugbu a na Western Europe, mmepụta olu nke plastic ihe karịrị mmepụta nke ígwè.

A na-akọwa mmụba nke oriri site na mmụba nke ngwaahịa ndị na-azụ ahịa, ebe ọ na-anọchi anya plastik, ọla na iko dị ka ihe maka arịa, nkwakọ ngwaahịa, ihe owuwu, ngwá electronic, wdg.

Uru nke ihe plastik na-enye ma e jiri ya tụnyere ihe ndị ọzọ bụ ndị a:

• Ha dị ọkụ, yabụ na-ebelata ọnụ ahịa njem.
• Ha na-adịte aka ma na-esikarị ike na nchekwa.
• Enwere ike imepụta ha n'ụdị na ngwa dị iche iche.
• Ha nwere njirimara mara mma dị ka ihe mkpuchi ọkụ, ọkụ na ọkụ eletrik.
• Enwere ike iji gị na ngwa nri.

A na-ahazi plastik dabere na ụkpụrụ DIN 7728 na DIN 16780 maka ngwakọta plastik.

Plastics bụ ihe ndị a na-akpọ organic nke a na-akpọ polymers, nke sitere na Petroleum ma ọ bụ Natural Gas, bụ ndị na-ebu Carbon C, hydrogen H, oxygen O na ihe ndị ọzọ dị ka nitrogen N, chlorine CL, sulfur S ma ọ bụ CO2. Ugbu a, naanị 4% nke mmanụ a na-agbanwe ka ọ bụrụ ihe plastik.

plastic a na-esi na mmanụ ala amịpụta site na usoro mgbawa ọkụ (na-agbaji), bụ nke ethylene, Propylene, Butylene na hydrocarbons ndị ọzọ kewara.

Ihe mejupụtara macromolecules, ma ọ bụ rọbas, bụ nke nwere ọtụtụ ihe nhazi dị mfe, nke a na-akpọ monomers; ebe nchikota nke ihe ndia na-enyere aka site na mmekorita nke kemịkalụ na-ebute polymers.

Kedu ihe bụ polymers?

A na-emepụta polymers site na njikọ nke ọtụtụ narị puku obere ụmụ irighiri ihe a na-akpọ monometers bụ ndị na-emepụta ụdọ dị iche iche.

Nkewa plastik:

• A na-ekewa plastik dịka usoro dị iche iche si dị, dabere na:
• Usoro polymerization. (polymerization, polycondensation, polyaddition).
• Ọdịdị polymer. (cystallinity, superstructures).

Omume / Njirimara nke polymer. (Ngwaahịa, plastik teknụzụ, plastik arụmọrụ dị elu).

Dabere na nke dị n'elu, a na-ekewa plastik n'ime:

• Thermoplastics. (Polyolefins, Vinyl ma ọ bụ acrylic polymers, Polyamides, Polyesters, wdg.)
• Thermostable.
• Elastomers.

Ihe eji arụ ọrụ nke akụrụngwa thermoplastic metụtara Degree of Polymerization, nke bụ ọnụọgụ na-atụ ọnụ ọgụgụ njikọ nke mejupụtara yinye molekụla. N'ezie, ogo nke polymerization dị elu, ka viscosity dị elu, nke na-eme ka ọkpụkpụ na-eguzogide mmiri na-agbawa agbawa, nke na-esiwanye ike, otú ahụ ka mmetụta na-eguzogide ya na, n'aka nke ọzọ, obere ọchịchọ nke crystallize, obere ikike ọzịza na obere mgbagwoju anya. .

N'ihe banyere ihe Elastomeric na Thermoset, ihe onwunwe ha na-adabere na Degree of Crosslinking, nke na-atụle pasent nke crosslinking point (njikọ n'etiti molecules) na usoro polymer. Ọganihu dị elu nke crosslinking, nke ukwuu na-eguzogide ihe onwunwe, nkwụsi ike ya na nkwụsị ọkụ ya.

Plastics dị ọkụ, enwere ike ịkpụzi ya ngwa ngwa, ha na-enye ezigbo anụ ahụ na akụrụngwa, enwere ike imepụta ya na agba dị iche iche, enwere ike ịgwakọta ya na plastik ndị ọzọ ma ọ bụ ihe inorganic, ha nwere ọkwa dị ala nke thermal na eletriki, ha na-eguzogide ọgwụ ndị na-emepụta kemịkalụ, na-enwe ike imegharị ya, a na-emegharị ya na / ma ọ bụ na-emegharị ya.
