I-Conical Twin Screw Extruders Iwuguqula Kanjani Imboni Yepulasitiki: I-Paradigm Shift Ekucubunguleni Okuhle

Emkhakheni oguquguqukayo wokucubungula amapulasitiki, ama-conical twin screw extruder (CTSEs) avele njengabashintshi begeyimu, aguqula indlela ama-polymer ahlanganiswa ngayo, axutshwe, futhi ahlanganiswe ne-homogenized. Le mishini eguquguqukayo ibeke izinga elisha lokusebenza nokusebenza kahle, ibhekana nezinselelo zezicelo ezifunwayo kanye nokuqhubekisela phambili imboni yepulasitiki emingceleni emisha yokuqamba izinto ezintsha. Lokhu okuthunyelwe kubhulogi kucubungula umthelela oguqulayo wama-CTSE, uhlola amakhono awo ayingqayizivele kanye nokushintsha kwe-paradigm akulethayo ekucutshungulweni kwezinhlobonhlobo zezinto zepulasitiki.

Kwembula Amandla E-Conical Twin Screw Extruder

Ama-CTSE abelana ngezimiso eziyisisekelo zokuklama zama-twin screw extruder (TSEs), esebenzisa izikulufu ezimbili eziphenduphendukayo ukuze zithuthe, zincibilike, futhi zixube ama-polymer. Kodwa-ke, ama-CTSE ayazihlukanisa ngokuhlanganisa idizayini yomphongolo oyiconical, lapho ububanzi bomphongolo buncipha kancane kancane ngasekugcineni kokukhipha. Le geometry eyingqayizivele inika izinzuzo ezimbalwa ezenza ama-CTSE abe yinketho ekhethwayo yohlu olubanzi lwezinhlelo zokusebenza ezinzima.

Ukuxuba Okuthuthukisiwe kanye ne-Homogenization

Ijiyomethri ye-conical barrel ikhuthaza ukuxubana okunamandla kanye ne-homogenization ye-polymer blends, izithasiselo, nama-filler, iqinisekisa ukusatshalaliswa okufanayo kwezinto ngesikhathi sokuncibilika. Leli khono eliphakeme lokuhlanganisa libalulekile ekukhiqizeni imikhiqizo yekhwalithi ephezulu enezakhiwo nokusebenza okungaguquki.

Ukucindezeleka Kwe-Shear Okuncishisiwe

Ukwehliswa kancane kancane kobubanzi bomgqomo kunciphisa ingcindezi ye-shear ekuncibilikeni kwe-polymer, kunciphisa ukuwohloka kwe-polymer nokuthuthukisa ikhwalithi yomkhiqizo. Lokhu kunenzuzo ikakhulukazi kuma-polymers azwela i-shear ajwayele ukuwohloka ngaphansi kwezimo eziphakeme zokugunda.

Ukuqina Kwe-Melt Okuthuthukisiwe

Idizayini eyi-conical ithuthukisa ukuzinza kwe-ncibilika, inciphisa ingozi yokuqhekeka kwe-ncibilika futhi iqinisekise inqubo ye-extrusion ebushelelezi, engaguquki. Lokhu kuzinza kubalulekile ekukhiqizeni imikhiqizo yekhwalithi ephezulu enobukhulu obufanayo kanye nezindawo ezingaphezulu.

Ukuhlukahluka Kwezicelo Ezifunayo

Ama-CTSE ahamba phambili ekuphatheni izinhlanganisela ezigcwaliswe kakhulu, ama-polymers azwela i-shear, kanye nengxube ye-polymer eyinkimbinkimbi, ayenze ilungele izinhlelo zokusebenza ezidinga ukuxutshwa okuphezulu kanye nekhwalithi yomkhiqizo. Lezi zicelo ezidingekayo zihlanganisa:

Ukufakelwa Kwezintambo Nekhebula: Ama-CTSE asetshenziswa kabanzi ekukhiqizeni izintambo ezisebenza kahle kakhulu kanye nokufakwa kwamakhebula, lapho ukuxubana okungaguquki nokuzinza kokuncibilika kubalulekile.

Ipulasitiki Yezokwelapha: Ikhono lokuphatha ama-polymers ebanga lezokwelapha azwelayo enza ama-CTSE afaneleke kahle ukukhiqiza amashubhu ezokwelapha, ama-catheter, nezinye izisetshenziswa zezokwelapha.

Ipulasitiki Yezimoto: Ama-CTSE asetshenziswa ekukhiqizeni amapulasitiki ezimoto, okuhlanganisa obhampa, amadeshibhodi, nezingxenye zokunquma zangaphakathi, lapho amandla aphezulu nokuqina kubalulekile.

Izicelo Zokupakisha: Ama-CTSE asetshenziselwa ukukhiqiza amafilimu neziqukathi zokupakisha ezisebenza kahle kakhulu, ezidinga izakhiwo zesithiyo eziphakeme namandla emishini.

I-Compounding kanye ne-Masterbatching: Ama-CTSE ahamba phambili ekuhlanganiseni nasekuhlanganiseni kahle, lapho ukuxutshwa okunembayo nokuhlakazwa kwezithasiselo nezigcwalisi kubalulekile.

Isiphetho

Ama-Conical twin screw extruder aguqule imboni yokucubungula amapulasitiki, anikeza inhlanganisela eyingqayizivele yamakhono abhekana nezinselele zezinhlelo zokusebenza ezinzima futhi alethe ikhwalithi yomkhiqizo ephezulu. Ukuxutshwa kwabo okuthuthukisiwe, ukucindezelwa kwe-shear okuncishisiwe, ukuncibilika okuthuthukisiwe, kanye nokuguquguquka kwezinto kuwenza abe amathuluzi abalulekile ezimbonini eziningi. Njengoba isidingo samapulasitiki asebenza kahle kakhulu siqhubeka sikhula, ama-CTSE asekulungele ukudlala indima ebalulekile ekulolongeni ikusasa lokucutshungulwa kwamapulasitiki, ukushayela emisha kanye nokuqhubekisela phambili imboni ekuphakameni okusha kobuhle.
