I-XPE: Izinto ezigoqayo eziqhubekayo zesitayela samahhala, ezisebenza kangcono kunemikhiqizo efanayo
I-XPE iyinto ye-polyethylene foam ehlanganiswe ngamakhemikhali, eyenziwe nge-resin ye-polyethylene ephansi, i-ejenti yokuxhumanisa kanye ne-ejenti yokukhipha amagwebu ngokusebenzisa i-foam eqhubekayo esezingeni lokushisa eliphezulu. Inamandla aphezulu okudonseka, ama-pores amancane kanye nokuthungwa okulula. Uma iqhathaniswa nezinto ze-PE, ingcono kakhulu ngokunwebeka, ukuqina, ukumelana nokukhanya kanye nokumelana nomthelela ngokomzimba. Ngaphezu kwalokho, ngoba i-XPE ngokwayo inezakhiwo ezinhle kakhulu njengezakhiwo zamakhemikhali ezizinzile, akulula ukubola, ayinaphunga futhi inwebeka kahle, isetshenziswa ensimini yokwakha (ungqimba lokuvikela umsindo, ungqimba lokuvikela ukushisa) kanye nezicelo zokuvikela (omata baphansi, ukugcwalisa amaphakheji, amabhodi okusurfa).
Izinto zokufaka igwebu ze-XPE zitholakala ngenqubo elandelayo: ukuxuba i-granulation → ukukhipha ishidi eliyinhloko → ukufaka igwebu elivundlile.
Okusho ukuthi, ngokuxuba amapulasitiki afana nezinto ze-polyethylene eziphansi (LDPE) nama-agent e-foam amakhemikhali kanye nama-agent e-cross-linking, ngokulandelana, ngokuxuba i-granulation, i-foam masterbatch kanye ne-cross-linking masterbatch kuyatholakala.
Ngemuva kwalokho, ama-masterbatches amabili afakwa ku-single screw extruder kanye nezinto zokusetshenziswa ze-LDPE ngokwesilinganiso. Ngemva kokukhipha okuncibilikisiwe, athunyelwa ku-calender enama-three-roll ngokusebenzisa i-sheet mold, bese egoqwa abe yi-XPE master sheet coils ngemva kokwakheka.
Okulandelayo, ama-coil eshidi le-XPE ayavuleka bese efakwa esithandweni esivundlile se-foam ukuze kufakwe i-foam. Ama-foam omoya oshisayo ajikelezayo asebenza ekushiseni okuphezulu.
