Kungani amanani ezibani ze-PS neze-PC emakethe ehluke kangaka? Namuhla, ngizokwethula izici zezinto ezimbili.
1. I-Polystyrene (PS)
• Isakhiwo: I-polymer e-Amorphous, Ukuncishiswa ngemva kokubumba ngaphansi kuka-0.6; ukuminyana okuphansi kwenza umkhiqizo ube mkhulu ngo-20% kuya ku-30% kunezinto ezijwayelekile
• Izinzuzo: izindleko eziphansi, ezibonakalayo, ezidayiwe, usayizi ozinzile, ukuqina okuphezulu
• Okubi: ukuqhekeka okuphezulu, ukumelana nokuncibilika okubi, ukumelana nokushisa
• Ukusetshenziswa: izinto zokubhala, amathoyizi, isikhwama sezinto zikagesi, izitsha zokudlala ze-styrofoam
2. I-Polycarbonate (PC)
• Impahla: Ama-thermoplastic angenasimo
• Izinzuzo: amandla aphezulu kanye ne-elastic modulus, amandla aphezulu okushaya, izinga lokushisa elibanzi lokusebenza, ukucaca okuphezulu kanye nokudaya okukhululekile, i-HDT ephezulu, ukumelana okuhle nokukhathala, ukumelana okuhle nesimo sezulu, izici zikagesi ezinhle kakhulu, ayinambitheki futhi ayinaphunga, ayinangozi emzimbeni womuntu, impilo nokuphepha, ukuncishiswa okuncane kokubumba kanye nokuzinza okuhle kobukhulu
• Okubi: Ukwakheka kabi komkhiqizo kungabangela kalula izinkinga zokucindezeleka kwangaphakathi
• Isicelo:
√ Izinto zikagesi: ama-CD, amaswishi, izindawo zokugcina izinto zasekhaya, izibhamu zesignali, izingcingo
√ Imoto: amabhampa, amabhodi okusabalalisa, ingilazi yokuphepha
√ Izingxenye zezimboni: imizimba yekhamera, izindlu zomshini, izigqoko zokuvikela, izibuko zokuntywila, amalensi okuphepha
3. Ezinye izimo
• Ukudlulisa ukukhanya kwe-PS kungu-92%, kanti kwe-PC kungu-88%.
• Ukuqina kwe-PC kungcono kakhulu kune-PS, i-PS iyaphuka futhi ingaphuka kalula, kuyilapho i-PC iqine kakhudlwana.
• Izinga lokushisa lokuguquguquka kokushisa kwe-PC lifinyelela kuma-degrees angu-120, kuyilapho i-PS ingama-degrees angu-85 kuphela.
• Ukugeleza kwalokhu okubili nakho kuhlukile kakhulu. Ukugeleza kwe-PS kungcono kune-PC. I-PS ingasebenzisa amasango akhombayo, kuyilapho i-PC ngokuyisisekelo idinga isango elikhulu.
• Intengo yalezi ezimbili nayo ihlukile kakhulu. ManjeokuvamileI-PC ibiza ngaphezu kwama-yuan angu-20, kuyilapho i-PS ibiza ama-yuan angu-11 kuphela.
Ipulasitiki ye-PS ibhekisela ku-ClassⅠplastic ehlanganisa i-Styrene ku-Macromolecular chain, futhi ihlanganisa ne-Styrene kanye ne-Copolymers. Iyancibilika kuma-hydrocarbon anuka kamnandi, ama-hydrocarbon aqukethe i-chlorinated, ama-Aliphatic Ketone kanye nama-ester, kodwa ingavuvukala kuphela ku-acetone.
I-PC ibizwa nangokuthi i-Polycarbonate, efushaniswe ngokuthi i-PC, iyinto engenambala, esobala, engenasimo se-thermoplastic. Leli gama livela eqenjini le-Internal CO3.
Ngiyethemba ukuthi kungasiza amakhasimende aqonde ukuthi kungani kunomehluko wamanani phakathi kwe-PC ne-PS. Ngiyethemba futhi ukuthi amakhasimende azohlala evulekile lapho ekhetha izibani, ungakhohliswa yintengo. Phela, uthola lokho okukhokhelayo.
I-Liper njengomkhiqizi wokukhanyisa ochwepheshe, siqinile kakhulu ekukhetheni izinto ezibonakalayo, ngakho-ke ungakhetha futhi uyisebenzise ngokuzethemba.
