Kungani amanani entengo amalambu e-PS nawe-PC emakethe ehluke kangaka? Namuhla, ngizokwethula izici zezinto ezimbili.
1. I-Polystyrene (PS)
• Impahla: I-polymer e-amorphous, I-Shrinkage ngemva kokubumba ngaphansi kuka-0.6; ukuminyana okuphansi kwenza okukhiphayo kube ku-20% kuya ku-30% kukhulu kunokuqukethwe okuvamile
• Izinzuzo: izindleko eziphansi, okusobala, okudayikayo, usayizi ongashintshi, ukuqina okuphezulu
• Ukungalungi: ukuhlukana okuphezulu, ukumelana ne-solvent embi, ukumelana nezinga lokushisa
• Isicelo: izinto zokubhala, amathoyizi, Ibhokisi likagesi likagesi, i-styrofoam tableware
2. I-Polycarbonate (PC)
• Isakhiwo: I-Amorphous thermoplastics
• Izinzuzo: amandla aphezulu kanye ne-elastic modulus, amandla omthelela aphezulu, ububanzi bezinga lokushisa elibanzi, ukukhanya okuphezulu nokudaya kwamahhala, i-HDT ephezulu, ukumelana nokukhathala okuhle, ukumelana nesimo sezulu esihle, izici ezinhle kakhulu zikagesi, azinambitheki futhi azinaphunga, azinangozi emzimbeni womuntu, empilweni. nokuphepha, ukuncipha kokubumba okuphansi kanye nokuzinza okuhle kwe-dimensional
• Ububi: Ukwakheka komkhiqizo okungekuhle kungabangela kalula izinkinga zengcindezi yangaphakathi
• Isicelo:
√ Ezogesi: Ama-CD, amaswishi, izindlu zikagesi zasendlini, izimbangi zamasignali, izingcingo
√ Imoto: obhampa, amabhodi okusabalalisa, ingilazi yokuphepha
√ Izingxenye zezimboni: imizimba yekhamera, izindlu zemishini, izigqoko zokuzivikela, izibuko zokutshuza, amalensi okuphepha
3. Ezinye izimo
• Ukukhanya kokukhanya kwe-PS kungu-92%, kuyilapho i-PC ingu-88%.
• Ukuqina kwe-PC kungcono kakhulu kune-PS, i-PS i-brittle futhi ingaphuka kalula, kuyilapho i-PC ikwazi ukuqina.
• Ukushisa kwe-thermal deformation ye-PC kufinyelela kuma-degree angu-120, kanti i-PS imayelana nama-85 degrees kuphela.
• Uketshezi lwalokhu okubili nakho kuhluke kakhulu. I-fluidity ye-PS ingcono kune-PC. I-PS ingasebenzisa amasango ephoyinti, kuyilapho i-PC idinga isango elikhulu.
• Inani lalokhu okubili nalo lihluke kakhulu. ManjeevamileI-PC ibiza ngaphezu kwama-yuan angu-20, kuyilapho i-PS ibiza amayuan angu-11 kuphela.
Ipulasitiki ye-PS isho i-ClassⅠplastic ehlanganisa i-Styrene kuchungechunge lwe-Macromolecular, futhi ihlanganisa i-Styrene nama-Copolymers. Incibilika kuma-Aromatic hydrocarbons, ama-Chlorinated hydrocarbons, Aliphatic Ketones nama-esters, kodwa ingavuvukala kuphela ku-acetone.
I-PC ibizwa nangokuthi i-Polycarbonate, efushanisiwe njenge-PC, iyimpahla engenambala, esobala, ne-amorphous thermoplastic. Igama livela eqenjini langaphakathi le-CO3.
Ngethemba ukuthi ingasiza amakhasimende aqonde ukuthi kungani kunomehluko wamanani phakathi kwe-PC ne-PS. Ngiyethemba futhi ukuthi amakhasimende azovula amehlo uma ekhetha amalambu, angakhohliswa amanani. Phela uthola lokho okukhokhelayo.
I-Liper njengomkhiqizi wokukhanyisa ochwepheshe, siqinile kakhulu ekukhetheni izinto ezibonakalayo, ngakho-ke ungakhetha futhi uyisebenzise ngokuzethemba.
