Lijana tsa polasetiki ke metsoako e entsoeng ka monotor ho tsoa ho thepa e tala ka ho ekelletsa le polymerization kapa khokahano ea polymeriation.
Chalymer Chain ke Photopolymer haeba e sebetsantsoe ke monotor e le 'ngoe. Haeba ho na le li-monomers tse ngata ka ketane ea polymer, polymer ke compleymer. Ka mantsoe a mang, polasetiki ke polymer.
2. TLHALOSO EA PAKA
Polasetiki e ka aroloa ka lepapa la litlolo ho latela mmuso kamora ho futhumatsoa.
Phula ea limela ke polasetiki e nang le thepa ea ho futhumatsa, ho folisa le ho e rarolla, eseng ho qhilla. Polasetiki ena e ka thehoa hanngoe feela.
Hangata ho na le ts'ebetso e ntle ea motlakase, 'me e ka mamella mocheso o phahameng o sebetsang.
Empa bothata ba eona bo bohlokoa ke hore lebelo la ts'ebetso ea sebetsa le ba thata ebile ho nchafatsa ho thatafala.

4. LITLHAKISO TSA BOPHELO LE LITLHAKISO TSA BOPHELO
Platotic e ka aroloa ka likarolo tse akaretsang, lithota tsa boenjiniere, lipolaisi tse khethehileng tsa boenjiniere tse khethehileng joalo-joalo.
Liphoso tse akaretsang tsa polasetiki ka kakaretso, mefuta e meholohali ea polasetiki e kenyelelitse: pe, pp, pvc, ps, e le joalo.
Lipina tsa boenjiniere: Plastics e sebelisoang e le lisebelisoa tsa boenjiniere le tse nkang thepa bakeng sa tsamaiso ea mechini, jj.
Liphuputso tsa boenjiniere li na le mokhoa o ikhethileng o ikhethileng, o tsitsitseng, o hanyetsang.
Hajoale, lienjiniere tse hlano tse tloaelehileng: Pa (polformalddehy Terephthahyde), PCT (Polybutlene Tereptha
Lipōlente tse khethehileng tsa boenjiniere: Liphutheloana tse khethehileng li bua ka mofuta o hlakileng oa boenjiniere o tsamaisa lipolente tse phahameng tse nang le litšila, 'me u sebelise mocheso o khethehileng ho feta 150 ℃. Haholo-holo e sebelisoa haholo ho elektroniki, indasteri e khethehileng le masimo a mang a maholo.

5. Liphoso life tsa theko e nepahetseng ke eng?
Ka puo eo re tloaetseng ho sebelisoa hangata ke macromolecule e telele e nang le tumellano le ho le thata ho li hlakola tikolohong ea tlhaho. Ho chesa kapa ho chesa ho ka baka kotsi e ngata, ka hona batho ba batla lipolanete tse senyehileng ho fokotsa khatello ea tikoloho.
Litekete tse mpe li aroloa haholo ka har'a polasetiki ea litšoantšo le lithotohelo tsa bidgradadadadadadadadadadadadadadadadadadadadadadadadana.
Setšoantšo sa lifoto: Tlas'a ts'ebetso ea khanya ea ultraviolet, ke mocheso oa polymer, e le ho fihlela sepheo sa ho nyonyeha.
Likheo tsa Biodegrable: Tlas'a Maemo a Tlhaho, likokoana-hloko ka tlhaho li senya liketane tsa meaho ea polymer, 'me qetellong likhechana tsa polasetiki le carbon dioxide.
Hajoale, liponto tse senyehileng tse mabifi tse nang le khoebo e ntle e kenyelletsa Pla, PBAT, joalo-joalo
