Ngaba uyazi malunga nemibhobho ye-PE?
2023-07-03
IUmgca wokuvelisa umbhobho we-PEyi-spiral die eyenzelwe i-HDPE kunye ne-PP imibhobho yodonga engqindilili yobubanzi obukhulu. Oku kufa kuneempawu zeqondo lokushisa eliphantsi lokunyibilika, ukusebenza kakuhle kokuxuba, uxinzelelo oluphantsi lokungunda, kunye nemveliso ezinzileyo.
IUmgca wokuvelisa umbhobho we-PEyamkela itekhnoloji yobunini yokulinganisa kunye neenkqubo zokupholisa, kusetyenziswa ukuthambisa ifilimu yamanzi kunye nokupholisa umsesane wamanzi ukuhlangabezana neemfuno ze-HDPE kunye nemathiriyeli yePP, iqinisekisa uzinzo lobukhulu kunye nokungqukuva kwimveliso enesantya esiphezulu semibhobho engqindilili.
Umgca wokuvelisa umbhobho we-PE uthatha i-vacuum sizeng eyilwe ngokukodwaibhokisi yokulawula iqondo le-vacuum, iqinisekisa ukuzinza kwe-dimensional kunye nokujikeleza kwe-HDPE kunye nemibhobho ye-PP. I-extruder kunye ne-traction machine ilawulwa ngabalawuli besantya abadumileyo abathunyelwa ngaphandle, abanozinzo oluhle, ukuchaneka okuphezulu, kunye nokuthembeka okuphezulu.
Imibhobho yonikezelo lwamanzi ye-PE yenziwe nge-polyethylene ekhethekileyo njengento ekrwada kwaye ikhutshwe nge-extruder yeplastiki ngexesha elinye. Zisetyenziswa kuthungelwano lonikezelo lwamanzi ezidolophini, iiprojekthi zokunkcenkceshela kunye nokuphambukiswa kwamanzi, kunye neeprojekthi zokunkcenkceshela zezolimo, ezilungele imibhobho yeplastiki ekwaziyo ukumelana ne-asidi, i-alkali, kunye neendawo zokubola. Ngenxa yokusetyenziswa kwe-melt eshushu kunye nokudibanisa kombane kwimibhobho ye-PE, ukudityaniswa kwe-interface kunye nombhobho kufezekiswa, kwaye kunokumelana ngokufanelekileyo noxinzelelo lwe-circumferential kunye noxinzelelo lwe-axial olubangelwa uxinzelelo. Ngaphezu koko, imibhobho ye-PE ayifaki i-stabilizers yetyuwa yensimbi enzima, kwaye izinto eziphathekayo azikho inetyhefu, ngaphandle kokulinganisa okanye ukuzala ibhaktheriya, ukuphepha ukungcoliseka kwesibini kwamanzi okusela.

Ukusebenza kunye nexesha leUmgca wokuvelisa umbhobho we-PEzisebenzisana nenkqubo elawulwa yi-PLC, kunye nojongano oluhle lomatshini womntu. Zonke iiparamitha zenkqubo zinokusetwa kwaye ziboniswe ngesikrini sokuchukumisa. I-extruder ezinikeleyo yokumakisha imigca inokudityaniswa ukuze ivelise imibhobho eneempawu ezinemibala ehambelana nemigangatho yelizwe.
