Umehluko phakathi komshini wokufunxa kanye ne-extruder

1, Incazelo kanye nesimiso sokusebenza somshini wokukhukhumeza kanye ne-extruder
Imishini yokukhukhumeza kanye ne-extruder iyimishini esetshenziswa kakhulu embonini yokucubungula ipulasitiki kanye nemboni yokucubungula ukudla. Nakuba kukhona ukufana phakathi kwalokhu kokubili, umehluko wabo obalulekile usabalulekile.

Umshini wokukhukhumeza usebenzisa izinga lokushisa eliphezulu nokucindezela okukhulu ukuze ukhulule inani elikhulu lomhwamuko wamanzi ngokuphazima kweso, okubangela ukuba izinto ezibonakalayo zikhule futhi ziwohloke, zikhiqize ukudla okukhukhumele ngevolumu enkulu, ukuthungwa okuxekethile, ukunambitheka okucwebezelayo nokuthambile, kanye nokugayeka kalula nokumuncwa, njengama-corn flakes nama-popcorn, okuwukudla okuvame kakhulu okukhukhumele. Isimiso sokusebenza somshini wokufutha ukushisa impahla ngaphansi kwezimo ezithile, okubangela ukucindezela kwawo okugcwele umhwamuko ukuthi kukhule ngokuqhubekayo, kudlule ukumelana nesakhiwo ngokwawo futhi kubangele ukubola. Khona-ke, umhwamuko uyanda ngaso leso sikhathi, ubangele ukuthi impahla ikhubazeke futhi yande ngokushesha, ngaleyo ndlela izuze umphumela wokukhukhumala.

I-Extruder iyinqubo yokushisisa nokuncibilika kwepulasitiki, bese iyikhipha esikhunjeni sensimbi ngaphansi kwengcindezi ephezulu ukuze ikhiqize izimo ezihlukahlukene zemikhiqizo yepulasitiki namapayipi, njengobucwebe, amathoyizi, njll. Umgomo wokusebenza we-extruder uthi: ngemva kokushisa kanye Ukuncibilika, okokusebenza kwe-thermoplastic kukhishwa ekhanda lesikhunta ngokusebenzisa ukucindezelwa okuphoqelekile kwesikulufu. Ngenxa yokucindezela okuphezulu kwe-extrusion, impahla ekhishweyo isesimweni esihlakazekile, bese yelulwa ngokuqhubekayo njengoba isikhunta sehla, sakha umugqa owufunayo noma imikhiqizo yepulasitiki enezimbobo eziyindilinga.

2. Umehluko phakathi komshini wokukhukhumeza kanye ne-extruder
Umehluko omkhulu phakathi kwemishini yokukhukhumeza kanye nama-extruder usezimisweni zabo zokusebenza, ububanzi bokufaka isicelo, nezinto zokucubungula.
1. Izimiso zokusebenza ezahlukene
Umshini wokukhukhumeza wakhiwa ngokuhwamuka nokukhukhumeza umswakama ngaphakathi kwempahla ngaphansi kwezinga lokushisa eliphezulu nokucindezela, kuyilapho i-extruder yakhiwe nge-spiral extrusion ngaphakathi kwepulasitiki.
2. Izinhlelo zokusebenza ezihlukene
Imishini yokukhukhumeza ifaneleka ngokukhethekile ukukhiqiza ukudla okukhukhumele okufana nama-corn flakes, imbewu ye-melon, njll. Futhi ama-extruders ayingxenye yemishini evamile, njengemishini ebalulekile yokukhiqiza imikhiqizo yepulasitiki, esetshenziswa kabanzi emikhakheni enjengokwakha, ukudla, ezolimo, njll.
3. Izinto ezahlukene zokucubungula
Imishini yokukhukhumeza isetshenziselwa ikakhulukazi ukucubungula izinto zemvelo ezifana nokusanhlamvu, kuyilapho ama-extruder asetshenziselwa ukucubungula izinto ze-polymer ezifana ne-PVC, i-PE, njll.
