Extrusion

I-Extrusion yinkqubo yokuvelisa umthamo ophezulu.Izinto zeplastiki zinyibilika ngokusetyenziswa kobushushu kwaye zigqithiswe ngokufa kwimilo efunekayo.Isikrufu esijikelezayo esisicylindrical sibekwe ngaphakathi komphanda nto leyo enyanzelisa ukuba kuphume imathiriyeli yeplastiki enyibilikisiweyo ngedayisi.Izinto ezikhutshiweyo zithatha imilo ngokwecandelo lokufa.

UmGaqo wokuSebenza

Kule nkqubo, izinto zeplastiki ngendlela yeepellets okanye i-granules yi-gravity eyondliwe ukusuka kwi-hopper ephezulu efakwe kwi-barrel.Izongezo ezifana ne-colorants kunye ne-ultraviolet inhibitors (i-liquid okanye i-pellet form) inokuxutywa kwi-hopper.Izinto zeplastiki zingena ngomqala wokutya kwaye zidibana nesikrufu esijikelezayo.Isikrufu esijikelezayo sityhala amaso eplastiki ukuya phambili emgqomeni.Umgqomo ushushu usebenzisa izinto zokufudumeza ukuya kwiqondo lokushisa elinyibilikayo leplastiki.Izinto zokufudumeza zisetyenziswe ngeendlela ezinokuthi zinyuse ngokuthe ngcembe ubushushu bombhobho ukusuka ngasemva ukuya ngaphambili.

Kukho imimandla emithathu enokwenzeka kwisikrufu esijikelezayo oko kukuthi indawo yokutya, indawo yokunyibilika, kunye nendawo yokulinganisa imitha.Kwindawo yokutya, amaso eplastiki anyibilika ngokuthe ngcembe njengoko etyhalwa ngomphanda.

Izinto zeplastiki zinyibilike ngokupheleleyo kwindawo yokunyibilika.I-thermostat isetyenziselwa ukugcina ubushushu bangaphakathi bombhobho.Ukugqithiswa kweeplastiki kufuneka kuncitshiswe okunokubangela ukuthotywa kwezinto eziphathekayo.I-fan yokupholisa okanye inkqubo yokupholisa amanzi isetyenziselwa ukugcina ubushushu bombhobho ngexesha lenkqubo.

Ngaphambili komphanda, iplastiki enyibilikisiweyo ishiya isikrufu kwaye idlule kwipakethi yesikrini ukususa nakuphi na ungcoliseko kwiplastiki etyhidiweyo.Izikrini ziqiniswa ngeplate ye-breaker.

Indibano yepleyiti ye-breaker iphinda isebenze ukudala uxinzelelo lwasemva kwi-barrel.Uxinzelelo lwangasemva lunika ukunyibilika okufanayo kunye nokuxuba okufanelekileyo kwezinto ezityhidiweyo zeplastiki kwi-barrel.Emva kokudlula kwipleyiti yokuqhekeza, iplastiki etyhidiweyo ingena kwifa.Ukufa kunika imilo efunekayo yemveliso yeplastiki.Ukuhamba ngokungalinganiyo kweplastiki etyhidiweyo kuya kuvelisa uxinzelelo olungafunekiyo kwimveliso yeplastiki.Olu xinzelelo lunokubangela i-warping emva kokuqiniswa kweplastiki etyhidiweyo.Iiplastiki zihle kakhulu kwi-thermal insulators kwaye ngoko ke kunzima kakhulu ukupholisa ngokukhawuleza.Imveliso yeplastiki ipholisiwe ngokutsalwa kwiseti yeeroli zokupholisa.

Iiparamitha zeNkqubo ye-Extrusion

Kukho iiparameters zenkqubo ezintlanu ezibalulekileyo ekufuneka ziqwalaselwe phambi kwenkqubo ye-extrusion:

1. Ukunyibilika kobushushu beplastiki
2. Isantya sesikrufu
3. Uxinzelelo lwe-Extrusion luyafuneka
4. Iintlobo zokufa ezisetyenzisiweyo
5. Isiphakathi sokupholisa
