Ugwebu lwePolystyrene (EPS)

I-EPS yipolima ekhaphukhaphu.Ngenxa yexabiso layo eliphantsi, ikwayeyona nto isetyenziswa kakhulu kwisixhobo sogwebu kuyo yonke indawo yokupakisha, ibalelwa phantse kuma-60%.I-polystyrene resin yenziwa ngokongeza i-ejenti enegwebu ngokufaka amagwebu kwangaphambili, ukunyanga, ukubumba, ukomisa, ukusika kunye nezinye iinkqubo.Isakhiwo esivaliweyo se-EPS sinquma ukuba sine-insulation efanelekileyo ye-thermal kunye ne-conductivity ephantsi ye-thermal.I-thermal conductivity yeebhodi ze-EPS zeenkcazo ezahlukeneyo ziphakathi kwe-0.024W / mK ~ 0.041W / mK Inokugcinwa kakuhle kobushushu kunye nefuthe lokugcinwa kwengqele kwi-logistics.

Nangona kunjalo, njengemathiriyeli ye-thermoplastic, i-EPS iyakunyibilika xa ishushu kwaye ibe qinileyo xa ipholile, kwaye ubushushu bayo be-thermal deformation bujikeleze i-70 °C, oku kuthetha ukuba ii-incubators ze-EPS ezicutshungulwe kwi-packaging yogwebu kufuneka zisetyenziswe ngaphantsi kwe-70 °C.Ukuba iqondo lokushisa liphezulu kakhulu, i-70 ° C, amandla ebhokisi aya kuncitshiswa, kwaye izinto ezinobuthi ziya kuveliswa ngenxa ye-volatilization ye-styrene.Ke ngoko, inkunkuma ye-EPS ayinakunyanzelwa ngokwemvelo, kwaye ayinakutshiswa.

Ukongeza, ukuqina kwee-incubators ze-EPS akulunganga kakhulu, ukusebenza kwe-cushioning kukwayinto eqhelekileyo, kwaye kulula ukonakala ngexesha lothutho, ngoko ke isetyenziswa kakhulu kusetyenziso lwexesha elinye, kubanda okwexeshana elifutshane. uthutho lwekhonkco, kunye namashishini okutya afana nenyama kunye neenkukhu.Iitreyi kunye nezinto zokupakisha zokutya okukhawulezayo.Ubomi benkonzo yale mveliso ngokuqhelekileyo bufutshane, malunga ne-50% yeemveliso ze-Styrofoam zinobomi benkonzo yeminyaka eyi-2 kuphela, kwaye i-97% yeemveliso ze-Styrofoam zinobomi benkonzo engaphantsi kweminyaka eyi-10, ebangela ukuba i-EPS foam ichithwe unyaka. ngonyaka, nangona kunjalo,EPS amagwebuakukho lula ukubola kunye nokuphinda kusetyenziswe, ngoko ngoyena nobangela wongcoliseko olumhlophe lwangoku: I-EPS ibala ngaphezu kwe-60% yenkunkuma emhlophe ekungcoleni kolwandle!Njengomathiriyeli wokupakisha we-EPS, uninzi lweearhente zogwebu zeHCFC zisetyenziswa kwinkqubo yogwebu, kwaye uninzi lweemveliso ziya kuba nevumba elikhethekileyo.Amandla okuphela kwe-ozone kwiiHCFCs ali-1,000 ngokuphindwe kali-1,000 kunecarbon dioxide.Ngoko ke, ukususela ngo-2010, iZizwe eziManyeneyo, i-United States, i-European Union, i-China, i-South Korea, i-Japan kunye namanye amazwe afanelekileyo (imibutho) kunye nemimandla idlulisele umthetho wokuthintela okanye ukukhawulela ukusetyenziswa kweplastiki enye, kuquka i-Styrofoam. , kwaye abantu baye baqulunqa ngenkani "Imephu yeNdlela eHlaziyiweyo".
