Hobaneng litheko tsa mabone a PS le PC 'marakeng li fapane hakaale? Kajeno, ke tla hlahisa litšobotsi tsa lisebelisoa tse peli.
1. Polystyrene (PS)
• Thepa: Amorphous polymer, Shrinkage ka mor'a ho bōpa ka tlaase ho 0.6; low density etsa tlhahiso 20% ho 30% kholo ho feta thepa kakaretso
• Melemo: theko e tlaase, e pepeneneng, e daeang, boholo bo tsitsitseng, ho tiea ho phahameng
• Mefokolo: ho arohana ho hoholo, ho hanyetsa ha solvent, ho hanyetsa mocheso
• Kopo: lintho tsa ho ngola, lintho tsa ho bapala, k'hasete ea lisebelisoa tsa Motlakase, lisebelisoa tsa tafole tsa styrofoam
2. Polycarbonate (PC)
• Thepa: Amorphous thermoplastics
• Melemo: matla a phahameng le elastic modulus, matla a nang le tšusumetso e matla, mocheso o pharaletseng oa mocheso, ponahalo e phahameng le ho daea mahala, HDT e phahameng, ho hanyetsa mokhathala o motle, ho hanyetsa boemo ba leholimo bo botle, litšobotsi tse ntle tsa Motlakase, tse sa latsoeheng le tse sa nkheng, tse se nang kotsi 'meleng oa motho, bophelo bo botle. le polokeho, shrinkage e tlase ea ho bopa le botsitso bo botle ba sebopeho
• Mefokolo: Moralo o fosahetseng oa sehlahisoa o ka baka mathata a ka hare habonolo habonolo
• Kopo :
√ Lisebelisoa tsa elektronike: li-CD, li-switch, matlo a lisebelisoa tsa lapeng, likanono tsa matšoao, mehala
√ Koloi: li-bumpers, liboto tsa kabo, likhalase tsa polokeho
√ Likarolo tsa indasteri: 'mele oa lik'hamera, matlo a mochini, lihelmete, likhalase tsa ho qoela, lilense tsa polokeho
3. Maemo a mang
• Phatlalatso ea leseli ea PS ke 92%, ha bakeng sa PC ke 88%.
• Matla a PC a molemo haholo ho feta PS, PS e brittle mme e ka robeha habonolo, ha PC e ntse e le matla haholoanyane.
• Mocheso oa mocheso oa mocheso oa PC o fihla ho likhato tse 120, ha PS e ka ba likhato tse 85 feela.
• The fluidity ea bobeli e boetse e fapane haholo. The fluidity ea PS e molemo ho feta ea PC. PS e ka sebelisa liheke tsa ntlha, ha PC e hloka heke e kholo.
• Theko ea tse peli e boetse e fapane haholo. JwaletloaelehilengPC e bitsa li-yuan tse fetang 20, ha PS e bitsa li-yuan tse 11 feela.
Plastiki ea PS e bua ka ClassⅠplastic e kenyelletsang Styrene ka har'a ketane ea Macromolecular, hape e kenyelletsa Styrene le Copolymers. E qhibiliha ka har'a hydrocarbons e nkhang hamonate, klorinated hydrocarbons, Aliphatic Ketones le ester, empa e ka ruruha feela ka har'a acetone.
PC e boetse e bitsoa Polycarbonate, e khutsufalitsoeng e le PC, ke thepa e se nang 'mala, e pepeneneng, ea amorphous thermoplastic. Lebitso le tsoa sehlopheng sa ka hare sa CO3.
Ke tšepa hore e ka thusa bareki ho utloisisa hore na ke hobane'ng ha ho na le phapang ea theko pakeng tsa PC le PS. Ke boetse ke tšepa hore bareki ba tla lula ba butse mahlo ha ba khetha mabone, ba se ke ba thetsoa ke theko. Etsoe, u fumana seo u se lefang.
Liper e le moetsi oa mabone a hloahloa, re thata haholo khethong ea thepa, kahoo o ka e khetha le ho e sebelisa ka kholiseho.
