Kunezindlela eziningi zokuhlukanisa isikhunta sepulasitiki sezimoto, ngokwezindlela ezahlukahlukene zeizingxenye zepulasitikiukwakha nokucubungula, zingahlukaniswa ngezigaba ezilandelayo.
1 - Isikhunta sokujova
Inqubo yokubumba yesikhunta sokujova ibonakala ngokubeka izinto zepulasitiki emgqonyeni oshisayo womshini womjovo. Ipulasitiki iyashiswa futhi incibilike, iphushwe isikulufu somshini womjovo noma i-plunger, bese ingena emgodini wesikhunta ngokusebenzisa umlomo wombhobho kanye nohlelo lokuthulula lwesikhunta, futhi ipulasitiki iyelapheka emgodini wesikhunta ngokulondoloza ukushisa, ukugcinwa kwengcindezi, nokupholisa. Njengoba idivayisi yokushisisa nokucindezela ingasebenza ngezigaba,ukubumba umjovoayikwazi nje ukubumba izingxenye zepulasitiki eziyinkimbinkimbi, kodwa futhi ibe nokusebenza kahle kokukhiqiza okuphezulu kanye nekhwalithi enhle. Ngakho-ke, ukubumba komjovo kuthatha ingxenye enkulu ekubunjweni kwezingxenye zepulasitiki, futhi isikhunta sokujova sithatha ngaphezu kwesigamu sokubumba kwepulasitiki. Umshini wokubumba umjovo usetshenziswa kakhulu ekubunjweni kwe-thermoplastics, kodwa eminyakeni yamuva nje ubuye usetshenziselwe ukubumba amapulasitiki e-thermosetting.
2-Isikhunta sokucindezela
Izibunjwa zokucindezela zibizwa nangokuthi isikhunta senjoloba esicindezelwe. Inqubo yokubumba yalesi sikhunta ibonakala ngokungeza izinto zokusetshenziswa zepulasitiki ngqo emgodini wokubumba ovulekile, bese uvala isikhunta, ngemva kokuba ipulasitiki incibilike ngaphansi kwesenzo sokushisa nokucindezela, igcwalisa umgodi ngokucindezela okuthile. Ngalesi sikhathi, isakhiwo samangqamuzana epulasitiki sikhiqiza ukusabela okuxhumanisa amakhemikhali, futhi kancane kancane kuqina futhi kumise ukuma. Isikhunta sokucindezela sisetshenziswa kakhulu kumapulasitiki e-thermosetting, futhi izingxenye zawo zepulasitiki ezibunjiwe zisetshenziselwa kakhulu igobolondo lokushintshwa kukagesi kanye nezidingo zansuku zonke.
3-Dlulisa isikhunta
Isikhunta sokudlulisa sibizwa nangokuthi isikhunta se-extrusion. Inqubo yokubumba yalesi sikhunta ibonakala ngokungeza izinto zepulasitiki ekamelweni lokugcwalisa elishisayo, bese ifaka ingcindezi ezintweni zepulasitiki ekamelweni lokugcwalisa ngekholomu yokucindezela, ipulasitiki iyancibilika ngaphansi kokushisa okuphezulu nokucindezela futhi ingena emgodini ngokuthulula. uhlelo lwesikhunta, bese kuthi ukuxhumanisa kwamakhemikhali kwenzeke futhi kancane kancane kuphuluke. Inqubo yokubumba yokudlulisa isetshenziswa kakhulu kumapulasitiki e-thermosetting futhi ingabumba izingxenye zepulasitiki ezinobunjwa obuyinkimbinkimbi.
4 - I-Extrusion Die
I-Extrusion die nayo ibizwa ngokuthi i-extrusion head. Lokhu kufa kungakhiqiza ngokuqhubekayo amapulasitiki anomumo ofanayo we-cross-sectional, njengamapayipi epulasitiki, izinduku, amashidi, njll. I-extruder iyashiswa futhi icindezeleke ngedivayisi efanayo nomshini womjovo. Ipulasitiki esesimweni esincibilikisiwe idlula ekhanda ukuze yakhe ukugeleza okuqhubekayo kwezingxenye zepulasitiki ezibunjiwe, futhi ukusebenza kahle kokukhiqiza kuphezulu kakhulu.
Ngaphezu kwalezi zinhlobo ezibalwe ngenhla zokubunjwa kwepulasitiki, kukhona nokubumba kwe-vacuum, isikhunta somoya esicindezelwe, isikhunta esiqhumayo, isikhunta sepulasitiki esinegwebu eliphansi, njll.
