Igwebu le-Polystyrene (EPS)

I-EPS iyi-polymer engasindi.Ngenxa yentengo ephansi, iphinde ibe yi-foam esetshenziswa kakhulu kuyo yonke inkundla yokupakisha, ibalwa cishe ngama-60%.I-polystyrene resin yenziwa ngokwengeza i-ejenti enegwebu ngokusebenzisa i-pre-foaming, ukuphulukisa, ukubumba, ukomisa, ukusika nezinye izinqubo.Isakhiwo se-cavity esivaliwe se-EPS sinquma ukuthi sinokufakwa okuhle kwe-thermal kanye ne-thermal conductivity ephansi.I-thermal conductivity yamabhodi e-EPS emininingwane ehlukahlukene iphakathi kuka-0.024W/mK~0.041W/mK Inokugcina ukushisa okuhle kanye nomthelela wokulondoloza ukubanda ku-logistics.

Kodwa-ke, njengempahla ye-thermoplastic, i-EPS izoncibilika lapho ishisisiwe futhi iqine uma ipholile, futhi izinga lokushisa layo lokushintsha okushisayo lilinganiselwa ku-70 °C, okusho ukuthi ama-incubator e-EPS acutshungulwa abe amaphakheji egwebu adinga ukusetshenziswa ngaphansi kuka-70 °C.Uma izinga lokushisa liphezulu kakhulu, i-70 ° C, amandla ebhokisi azoncishiswa, futhi izinto ezinobuthi zizokhiqizwa ngenxa ye-volatilization ye-styrene.Ngakho-ke, imfucuza ye-EPS ayikwazi ukuncishiswa ngokwemvelo, futhi ayikwazi ukushiswa.

Ngaphezu kwalokho, ukuqina kwe-EPS incubators akukuhle kakhulu, ukusebenza kwe-cushioning nakho kujwayelekile, futhi kulula ukonakala ngesikhathi sokuthutha, ngakho-ke kusetshenziselwa ukusetshenziswa kwesikhathi esisodwa, emakhazeni wesikhashana, afushane. ezokuthutha ngamaketanga, nezimboni zokudla ezifana nenyama nezinkukhu.Amathreyi nezinto zokupakisha zokudla okusheshayo.Impilo yesevisi yale mikhiqizo ivamise ukuba mfishane, cishe u-50% wemikhiqizo ye-Styrofoam inempilo yesevisi yeminyaka emi-2 kuphela, kanti i-97% yemikhiqizo ye-Styrofoam inempilo yesevisi engaphansi kweminyaka eyi-10, okwenza igwebu le-EPS lichithwe unyaka. ngonyaka, Nokho,I-EPS Foamakulula ukubola nokugaywa kabusha, ngakho-ke iyimbangela eyinhloko yokungcoliswa okumhlophe kwamanje: I-EPS ibala ngaphezu kuka-60% kadoti omhlophe ekungcolisweni kolwandle!Njengempahla yokupakisha ye-EPS, iningi lama-ejenti afaka amagwebu e-HCFC asetshenziswa enqubweni yokukhipha amagwebu, futhi imikhiqizo eminingi izoba nephunga elingavamile.Amandla okuphela kwe-ozone ama-HCFC aphindwe izikhathi eziyi-1,000 kune-carbon dioxide.Ngakho-ke, kusukela ngawo-2010, iZizwe Ezihlangene, i-United States, i-European Union, i-China, iNingizimu Korea, iJapane namanye amazwe afanelekile (izinhlangano) nezifunda ziye zaphasisa umthetho wokwenqabela noma ukukhawulela ukusetshenziswa kwamapulasitiki asetshenziswa kanye, kuhlanganise ne-Styrofoam. , futhi abantu baklame ngenkani “Imephu Yomgwaqo Ebuyekeziwe”.
