Metheo ea ts'ebetso ea ente ea ho bopa ea polasetiki bakeng sa tlhahiso ea karolo ea polasetiki

Lisebelisoa tsa polasetiki li ngolisitse nts'etsopele e ikhethang lilemong tse 50 tse fetileng, tse fetang tsa lisebelisoa tse ling tsa bareki.

Hona joale Europe Bophirimela, bophahamo ba modumo ea tlhahiso ea polasetiki thepa feta tlhahiso ea tšepe.

Keketseho ea ts'ebeliso e hlalosoa haholo ke keketseho ea lihlahisoa tsa bareki, kaha boholo ba tsona li nkile sebaka sa polasetiki, tšepe le likhalase e le lisebelisoa tsa lijana, liphutheloana, thepa ea kaho, lisebelisoa tsa elektroniki, joalo-joalo.

Melemo e fanoang ke thepa ea polasetiki ha e bapisoa le lisebelisoa tse ling ke tse latelang:

• Li bobebe 'me kahoo li fokotsa litšenyehelo tsa lipalangoang.
• Li tšoarella 'me hangata li matla ebile li bolokehile.
• Li ka etsoa ka mefuta e mengata ea libopeho le lisebelisoa.
• Li na le litšobotsi tse ntle tse kang mocheso oa mocheso, acoustic le motlakase.
• U ka sebelisoa lits'ebetsong tsa lijo.

Lipolasetiki li hlophisitsoe ho latela maemo a DIN 7728 le DIN 16780 bakeng sa metsoako ea polasetiki.

Lipolasetiki ke lintho tsa tlhaho tse bitsoang li-polymers, tse nkiloeng ho Petroleum kapa Khase ea Tlhaho, e leng bajari ba Carbon C, hydrogen H, oxygen O le limolek'hule tse ling tse kang nitrogen N, chlorine CL, sulfur S kapa CO2. Hona joale, ke 4% feela ea oli e fetoloang lisebelisoa tsa polasetiki.

polasetiki e ntšoa ho petroleum ka mokhoa oa ho futhumatsa mocheso (ho phunyeha), moo Ethylene, Propylene, Butylene le li-hydrocarbon tse ling li arohanang.

Li-macromolecules, kapa li-plastiki, li entsoe ka lihlopha tse ngata tse bonolo tsa meralo, tse bitsoang monomers; ha motsoako oa tsena o thusoa ke ho sebelisana ha lik'hemik'hale o hlahisa li-polymers.

Li-polymers ke eng?

Li-polymers li hlahisoa ke kopano ea limolek'hule tse nyenyane tse makholo a likete tse bitsoang li-monometers tse etsang liketane tse fapaneng haholo.

Plastiki Classification:

• Plastiki e arotsoe ho latela maemo a fapaneng, ho ipapisitsoe le:
• Polymerization mochine. (polymerization, polycondensation, polyaddition).
• Sebopeho sa polima. (crystallinity, superstructures).

Boitšoaro (bo-it-ha-be-tso) /thepats of the polymer. (Lihlahisoa, lipolasetiki tsa tekheniki, lipolasetiki tsa ts'ebetso e phahameng).

Ho latela se boletsoeng ka holimo, li-plastiki li arotsoe ka lihlopha tse latelang:

• Thermoplastics. (Polyolefin, Vinyl kapa Acrylic Polymers, Polyamides, Polyester, joalo-joalo)
• Thermostable.
• Li-elastomers.

Thepa ea mochini ea thepa ea thermoplastic e amana le Degree ea Polymerization, e leng palo e lekanyang palo ea likhokahano tse etsang ketane ea limolek'hule. Ha e le hantle, ha tekanyo ea polymerization e phahame, e na le viscosity e phahameng, ho hanyetsa ho hoholo le ho taboha, ho ba thata le ho feta, ho ba le tšusumetso e matla ea ho hanyetsa, ka lehlakoreng le leng, tšekamelo e fokolang ea ho khanya, bokhoni bo fokolang ba ho ruruha le ho fokotseha ha khatello ea kelello. .

Tabeng ea lisebelisoa tsa Elastomeric le Thermoset, thepa ea bona e hlophisitsoe ke Degree of Crosslinking, e lekanyang peresente ea lintlha tse kopanyang (ho tlamahanngoa pakeng tsa limolek'hule) tsamaisong ea polymer. Ha tekanyo ea crosslinking e phahame, ho na le khanyetso e kholo ea thepa, ho tiea ha eona le ho hanyetsa mocheso.

Lipolasetiki li bobebe, li ka bōptjoa habonolo, li fana ka thepa e ntle haholo ea 'mele le ea mechine, li ka etsoa ka mebala e fapaneng, li ka kopanngoa le lipolasetiki tse ling kapa ka thepa ea tlhaho, li na le maemo a tlaase haholo a mocheso le motlakase, li hanyetsana haholo le lisebelisoa tsa lik'hemik'hale, lia khoneha, li ka sebelisoa hape / kapa li ka sebelisoa hape.
