Yintoni iUses kunye neePropati zePolystyreneIphepha lesipili

I-Polystyrene (PS) yipolymer yokwenziwa eyenziwe kwi-styrene monomer, ecacileyo, i-amorphous, i-thermoplastic yempahla ye-nonpolar ekulula ukusetyenzwa kwaye inokuguqulwa ngokulula ibe linani elikhulu leemveliso ezigqityiweyo njenge-foam, iifilimu, kunye namaphepha. .Yenye yezona zinto zinkulu zeplastiki yemveliso, equka malunga neepesenti ezisixhenxe zemarike ye-thermoplastic iyonke.

I-PS sisithinteli sombane esilunge kakhulu, sicace kakuhle kakhulu ngenxa yokunqongophala kwekristale, kwaye inokumelana kakuhle neekhemikhali kwiiasidi ezidilulweyo kunye neziseko.Nangona kunjalo, i-polystyrene inemida emininzi.Ihlaselwe zizinyibilikisi ze-hydrocarbon, ineoksijini engekho mgangathweni kunye nokuxhathisa kwe-UV, kwaye kunokuba brittle, oko kukuthi, inamandla okuchaphazeleka kakubi ngenxa yokuqina komqolo wepolymer.Ngaphaya koko, umda wayo wobushushu obuphezulu wokusetyenziswa rhoqo uphantsi ngenxa yokunqongophala kwekristale kunye nobushushu bayo obusezantsi beglasi obumalunga ne-100°C.Ngezantsi kwe-Tg yayo, inamandla aphakathi ukuya phezulu (35 - 55 MPa) kodwa amandla empembelelo ephantsi (15 - 20 J / m).Ngaphandle kwabo bonke obu buthathaka, iipolymers ze-styrene zinomtsalane kakhulu iiplastiki zempahla yexabiso elikhulu.

Iphepha le-polystyrene lihlala lincinci kwaye lincinci kunephepha le-acrylic kodwa lihlala lixabisa kancinci kunezinye iiplastiki.Inokukhanya okuphezulu (kweyesibini kuphela kwi-acrylic sheets ekudluliseni ukukhanya), ukuchasana kwempembelelo yayo, ukumelana nemozulu kunye nokumelana nokuguga kubi ngaphezu kwe-plexiglass, iimpawu zomatshini kunye neempawu zokulungiswa kwe-thermal azilungile njenge-plexiglass, ukuqina kufana ne-plexiglass acrylic, amanzi. ukufunxa kunye nokwandiswa kwe-thermal coefficient ingaphantsi kwe-plexiglass acrylic, kodwa ixabiso layo lisezantsi kune-plexiglass acrylic.

I-Polystyrene yimathiriyeli ekhethwayo kwizicelo ezininzi ezibandakanya ukupakishwa kokutya, iimpahla zeplastiki ezilahlwayo zabathengi kunye neenxalenye ze-optical, i-elektroniki / yombane, kunye nezicelo zonyango.
