Iinkqubo ezintathu zokubumba nge-Blow
Kwinkqubo yokuvelisa ibhotile yeplastiki yokuhombisaKwizikhongozeli, unokuva amagama angobuchwephesha afana ne-extrusion blow molding (EBM), i-injection stretch blow molding (ISBM), kunye ne-injection blow molding (IBM). Eli nqaku lichaza ngokufutshane umahluko phakathi kwezi nkqubo zintathu kunye neemveliso ezinxulumene nazo kubaphathi beemveliso:
Ukubunjwa kwe-extrusion blow molding ye ibhotile yeplastiki yokuhombisayindlela yokwenza iindawo ze-thermoplastic ezingenanto. Izinto zokubumba ezidumileyo ziquka iibhotile, iibhakethi, iitini, iibhokisi, nazo zonke izikhongozeli zokupakisha ukutya, iziselo, izinto zokuthambisa, amayeza, kunye nezinto ezifunekayo zemihla ngemihla. Izikhongozeli ezinkulu zokubumba ezivuthayo zihlala zisetyenziselwa ukupakisha iimveliso zeekhemikhali, izinto zokuthambisa, kunye nezinto ezininzi. Ixabiso lokucubungula kule nkqubo liphakathi, kwaye ixabiso leyunithi liphantsi. Iimveliso eziqhelekileyo zisetyenziselwa ikakhulu ukupakisha izikhongozeli zeemveliso zeekhemikhali, ukupakisha izikhongozeli zeemveliso zabathengi, kunye nokupakisha izikhongozeli zamayeza. Zifanelekile kuphela kwimveliso enkulu, enomgangatho ophezulu, ubukhulu bodonga obufanayo, kunye nonyango lomphezulu olufanelekileyo ukugqitywa okugudileyo, okuqandisiweyo, kunye nokuthungwa.
Inkqubo yokubumba nge-injection blow ibhotile yeplastiki yokuhombisaOkokuqala ifaka iplastiki enyibilikisiweyo kwi-injection mold ukuze yenze ibhotile engenanto. Ibhotile engenanto emva koko yenziwe kwi-injection engenanto enomngxuma omncinci enomngxunya omncinci kumda. Emva koko, ifuduselwa kwi-blow mold isashushu. Emva koko, i-injection ivaliwe kwaye umoya ocinezelweyo ungeniswa ngombhobho wentonga engundoqo ukuze ivuthele ibhotile engenanto kwaye iyenze inamathele eludongeni lomngxuma. Ekugqibeleni, emva kokubamba uxinzelelo kunye nokupholisa, umoya ocinezelweyo uyakhululwa kwaye i-injection ivulwe ukuze kususwe inxalenye yeplastiki. Ifanelekile kuphela kwimveliso enkulu, enomgangatho ophezulu, ubukhulu bodonga obufanayo, kunye nonyango lomphezulu olufanelekileyo kwiimpahla ezigudileyo, eziqandisiweyo, nezinobume obuthambileyo.
Ukubumba i-Injection stretch blow of ibhotile yeplastiki yokuhombisa, eyaziwa ngokuba yi-ISBM, kuqala isebenzisa umatshini wokubumba inaliti ukufaka ibhotile engenanto, emva koko yolulwe ngobude ize ivuthelwe ngomoya ocinezelweyo ukuze yolulwe ngohlangothi, nto leyo ephumela kwimveliso enobume obufanayo nobomngxuma wokubumba. Ngokwenkqubo yokubumba imveliso, inokwahlulwa ibe yi-ISBM enenyathelo elinye kunye ne-ISBM enenyathelo ezimbini.
Ukongeza kwezi nkqubo zintathu ziqhelekileyo zokubumba umphunga ibhotile yeplastiki yokuhombisaIzixhobo zokupakisha kwisikhongozeli, kukwakho nokubumba ngenaliti, ukubumba ngokucinezela, kunye nokwenza i-vacuum. Kwixesha elizayo, siza kwazisa ulwazi oluthe kratya ngezinto zokupakisha ezihambelanayo ukuze ubhekisele kuzo xa ufunda ngeemveliso zezinto zokupakisha zokuhombisa, kunye nokwenza kube lula ukunxibelelana ngempumelelo nenkonzo yethu yabathengi xa uthenga izinto zokupakisha kwixesha elizayo.
