Ke hobane'ng ha litheko tsa mabone a PS le a PC 'marakeng li fapane hakaale? Kajeno, ke tla hlahisa litšobotsi tsa thepa e 'meli.
1. Polystyrene (PS)
• Thepa: Polima e sa fetoheng, Ho fokotseha ha metsi ka mor'a ho bopa ka tlase ho 0.6; boima bo tlase bo etsa hore tlhahiso e be kholo ho feta thepa e akaretsang ka 20% ho isa ho 30%.
• Melemo: theko e tlase, e bonaletsang, e ka dauoa, boholo bo tsitsitseng, ho tiea ho hoholo
• Mathata: ho arohana ho hoholo, ho hanyetsa dikhemikhale hampe, ho hanyetsa mocheso
• Tšebeliso: lisebelisoa tsa ho ngola, lintho tsa ho bapala, sekoahelo sa lisebelisoa tsa motlakase, lisebelisoa tsa tafole tsa styrofoam
2. Polycarbonate (PC)
• Thepa: Thermoplastics e se nang sebopeho
• Melemo: matla a phahameng le modulus e tenyetsehang, matla a phahameng a tšusumetso, mocheso o pharaletseng oa ts'ebetso, ponaletso e phahameng le ho daea ka bolokolohi, HDT e phahameng, ho hanyetsa mokhathala hantle, ho hanyetsa boemo ba leholimo hantle, litšobotsi tse ntle tsa motlakase, ho se latsoehe le ho se nkhang hamonate, ho se kotsi 'meleng oa motho, bophelo bo botle le polokeho, ho fokotseha ha sebopeho le botsitso bo botle ba litekanyo.
• Mathata: Moralo o mobe oa sehlahisoa o ka baka mathata a khatello ea ka hare habonolo
• Kopo:
√ Lisebelisoa tsa elektroniki: li-CD, liswichi, matlo a lisebelisoa tsa lapeng, likanono tsa lipontšo, lithelefono
√ Koloi: libampara, mapolanka a kabo, khalase ea polokeho
√ Likarolo tsa indasteri: 'mele ea lik'hamera, matlo a mochini, lihelmete, likhalase tsa ho qoela, lilense tsa polokeho
3. Maemo a mang
• Phetiso ea leseli ea PS ke 92%, ha bakeng sa PC e le 88%.
• Ho tiea ha PC ho betere haholo ho feta PS, PS e robeha habonolo mme e ka robeha habonolo, ha PC e le matla haholoanyane.
• Mocheso oa phetoho ea mocheso oa PC o fihla likhatong tse 120, ha PS e le likhato tse ka bang 85 feela.
• Ho phalla ha tse peli le hona ho fapane haholo. Ho phalla ha PS ho molemo ho feta ha PC. PS e ka sebelisa liheke tsa lintlha, ha PC e hloka heke e kholo.
• Theko ea tse peli le eona e fapane haholo. JoaletloaelehilengPC e bitsa chelete e fetang li-yuan tse 20, ha PS e bitsa li-yuan tse 11 feela.
PS plastic e bolela ClassⅠplastic e kenyeletsang Styrene ka har'a ketane ea Macromolecular, 'me e boetse e kenyelletsa Styrene le Copolymers. E qhibiliha ka har'a li-hydrocarbon tse nkhang hamonate, li-hydrocarbon tse nang le chlorine, li-Ketone tsa Aliphatic le li-ester, empa e ka ruruha feela ka har'a acetone.
PC e boetse e bitsoa Polycarbonate, e khutsufalitsoeng e le PC, ke thepa ea thermoplastic e se nang 'mala, e bonaletsang, e sa fetoheng. Lebitso lena le tsoa sehlopheng sa CO3 sa kahare.
Ke tšepa hore e ka thusa bareki ho utloisisa hore na ke hobane'ng ha ho na le phapang ea litheko pakeng tsa PC le PS. Hape ke tšepa hore bareki ba tla lula ba butse mahlo ha ba khetha mabone, le se ke la thetsoa ke theko. Etsoe, u fumana seo u se lefang.
Liper joalo ka moetsi oa mabone oa litsebi, re thata haholo ho khethoeng ha thepa, kahoo u ka e khetha le ho e sebelisa ka kholiseho.
