Umbhobho we-PE (umbhobho we-HDPE) wenziwa nge-polyethylene njengeyona nto iphambili eluhlaza, yongeza i-antioxidants, i-carbon black kunye nezixhobo zombala.Ibonakala ngoxinzelelo oluphantsi, amandla athile aphezulu, ukumelana nobushushu obuphantsi kunye nokuqina, kwaye iqondo lobushushu le-embrittlement linokufikelela kwi-80 °C.
Iplastiki yombhobho we-PE inokucutshungulwa kwaye yenziwe ngeendlela ezahlukeneyo ukwenza iimveliso ezahlukeneyo ezifana neefilimu, amaphepha, imibhobho, iiprofayili, njl.;kwaye ilungele ukusika, ukudibanisa kunye nokucubungula "i-welding".Iplastiki kulula ukuyibala kwaye inokwenziwa ibe yimibala eqaqambileyo;inokucutshungulwa kwakhona ngokuprinta, i-electroplating, ukuprinta kunye ne-embossing, ukwenza iiplastiki ezityebileyo kwimiphumo yokuhlobisa.
Uninzi lweeplastiki zinokumelana ne-corrosion eyomeleleyo kwi-asidi, i-alkali, ityuwa, njl. kunezixhobo zetsimbi kunye nezinye izinto ezingaphiliyo, kwaye zifanelekile ngokukodwa kwiingcango kunye neefestile, imigangatho, iindonga, njl. kwizityalo zekhemikhali;i-thermoplastics inokunyibilika ngezinye izinyibilikisi ze-organic, ngelixa iiplastiki ze-thermosetting ayinakunyibilika, kuphela ukudumba okuthile.Iiplastiki zikwanazo nokuxhathisa okulungileyo kokusingqongileyo kumanzi okusingqongileyo, ukufunxwa kwamanzi aphantsi, kwaye zinokusetyenziswa ngokubanzi kwiiprojekthi ezingangeni manzi kunye nobungqina bokufuma.
Ukumelana nobushushu kweeplastiki zepayipi ze-PE azikho phezulu.Xa iphantsi kwemithwalo kumaqondo obushushu aphezulu, ithande ukuthamba kwaye igqwese, okanye ide ibole kwaye yonakalise.Ubushushu bokutshintsha ubushushu be-thermoplastics eqhelekileyo yi-60-120 °C, kwaye ziintlobo ezimbalwa kuphela ezinokuthi zisetyenziswe ixesha elide malunga ne-200 °C..Ezinye iiplastiki kulula ukubamba umlilo okanye zitshise ngokucothayo, kwaye umsi omninzi wetyhefu uya kuveliswa xa kutsha, okubangela iingozi xa kutsha izakhiwo.I-coefficient yokwandiswa komgca weplastiki inkulu, amaxesha angama-3-10 amakhulu kuneyentsimbi.Ngoko ke, i-deformation deformation inkulu, kwaye izinto eziphathekayo zonakaliswa lula ngenxa yokuqokelela uxinzelelo lwe-thermal.
Ngenxa yokusebenza kwayo okuphezulu kobushushu obuphantsi kunye nokuqina kwayo, inokumelana nomonakalo wesithuthi kunye nokungcangcazela koomatshini, isenzo sokunyibilika komkhenkce kunye notshintsho olukhawulezileyo kuxinzelelo lokusebenza.Ngoko ke, imibhobho edibeneyo ingasetyenziselwa ukufakwa okanye ukulima ukwakhiwa, okulungele ukwakhiwa kunye neendleko eziphantsi zobunjineli;Udonga lombhobho lugudileyo, ukuchasana kokuhamba okuphakathi kuncinci, ukusetyenziswa kwamandla okuhambisa okuhambayo kuphantsi, kwaye akukho khemikhali idliwe yi-hydrocarbons yolwelo kwindawo yokuhambisa.Imibhobho ye-PE yoxinaniso oluphakathi kunye noluphezulu lufanelekile kwigesi yasezidolophini kunye nemibhobho yegesi yendalo.Imibhobho ye-PE enoxinano oluphantsi ifanelekile kwimibhobho yamanzi okusela, i-cable conduits, imibhobho yokutshiza yezolimo, imibhobho yesikhululo sokupompa, njl njl.
