Umehluko phakathi kwesikulufo esisodwa kanye nesikulufo esiphindwe kabili

I-extruder eyodwa yesikulufo: ifanelekela ukudla okuhlanganisiwe kwemfuyo kanye nezinkukhu.

I-extruder yama-twin screw: ngokuvamile isetshenziswa ekukhiqizweni kokudla kwasemanzini nasezifuyweni okunenani eliphezulu, njenge-eel, ufudu, kanye nokudla kwezinhlanzi ezincane, ngoba amanani ale mikhiqizo athengiswa emakethe anele ukukhokha izindleko zokukhiqiza imikhiqizo kusetshenziswa ubuchwepheshe be-twin screw; Ngaphezu kwalokho, okunye ukudla kwasemanzini okukhethekile, njengokudla kwasemanzini okunama-particulate (okunobubanzi obungu-0.8 ~ 1.5mm), ukudla kwasemanzini okunamafutha amaningi, kanye nokudla okunomthamo omncane wokukhiqiza kodwa ifomula eshintsha njalo, nakho kudingeka kukhiqizwe kusetshenziswa i-extruder yama-twin screw.

Kufanele kucaciswe ukuthi umehluko ongenhla awuqinisekile. Isibonelo, siphakamisa ukusebenzisa izikulufo ezimbili ukukhiqiza ukudla kwasemanzini, kodwa manje izinkampani eziningi zisebenzisa izikulufo ezilodwa ukukhiqiza ukudla kwasemanzini. Kunomehluko ekusetshenzisweni kwalezi ezimbili ekudleni kwasemanzini. Ngamafuphi, uma kuqhathaniswa nesikulufo esisodwa, isikulufo esiphindwe kabili sinezinzuzo ezilandelayo:

① Ukuzivumelanisa nezimo kwezinto zokusetshenziswa kubanzi, okungazivumelanisa nokucutshungulwa kwe-viscosity ephezulu, i-viscosity ephansi, okuqukethwe uwoyela okuphezulu, umswakama ophezulu noma i-viscosity, izinto zokusetshenziswa ezinamafutha, ezimanzi kakhulu, nezinye izinto ezingase zingene ku-screw eyodwa (SSE).

② Kunemikhawulo embalwa ngobukhulu bezinhlayiya zezinto zokusetshenziswa, ezingazivumelanisa nokucutshungulwa kwezinto zokusetshenziswa kusukela ku-micro powder kuya ku-coarse powder particles kanye nokucutshungulwa kwesikulufo esisodwa kwezinto ezinobukhulu bezinhlayiya ngaphandle kobubanzi obuthile.

③ Ukugeleza kwezinto ngaphakathi komgqomo kuyafana kakhulu, futhi umusi, amanzi, njll. kungangezwa ukuze kufezwe umphumela ofiselekayo womkhiqizo.

④ Ikhwalithi yangaphakathi neyangaphandle yomkhiqizo ingcono, okungafinyelela isimo esihle kakhulu sokufana futhi kwenze isakhiwo sama-molecule sezinto sihlelwe ngokulinganayo. Ubuso bubushelelezi ngesikhathi senqubo yokukhipha. Izinhlayiya zomkhiqizo zinokufana okuphezulu kanye nokufana okuhle.

⑤ Umphumela wokuvuthwa kanye nokuhlanganiswa kwezakhi zomzimba ungcono, ngokuvamile ngezinga lokuvuthwa kwesitashi elingaphezu kuka-95%, okwenza ukudla kwasemanzini okucutshunguliwe kukwazi ukugcina ukuqina emanzini, kuvimbele ukulahleka kwezakhamzimba zomkhiqizo, futhi kube lula ukukugaya nokumunca.

⑥ Isivuno esiphezulu ngaphansi kwamandla alinganayo. Ukusebenza kahle kokuxuba kwenza ukushisa okutholwa yizinto kuhambisane ngesikhathi, kusheshise izinga lokuvuthwa kwezinto, kunciphisa ukuguquguquka kwezinga lokushisa lezinto, futhi kuthuthukise umkhiqizo wemikhiqizo ekhishwe.

⑦ Ukwehlukahluka komkhiqizo kanye nokuzivumelanisa nezimo kubanzi, futhi ungacubungula ukudla okuncane kwasemanzini, ifomula ephezulu kawoyela, okuqukethwe umswakama okuphezulu, imikhiqizo yokunamathela ephezulu, kanye nemibala eminingi, uhlobo lwesangweji, kanye nemikhiqizo ekhethekile enomumo.

⑧ Ukusebenza kwenqubo kulula kakhulu, futhi ijubane le-spindle lingalungiswa ngokwezidingo zomkhiqizo ocutshungulwayo. Ngenxa yesici sokuzihlanza, ukuhlanza kulula kakhulu, futhi asikho isidingo sokuqaqa imishini ngemva kokucubungula ngakunye.

⑨ Izingxenye ezisengozini ziguga kancane. Umbono ovamile oyiphutha ukuthi isikulufu esisodwa siguga kancane. Eqinisweni, ngesikhathi senqubo yokukhipha izikulufu ezimbili, ngenxa yokuthuthwa kwezinto ezizinzile kanye nezici zokugeleza kwezinto, ukuguga kwezinto ezikulesikulufu kanye nomkhono wangaphakathi womgqomo kuncane kunokwesikulufu esisodwa. Nakuba inani lezikulufu liyisethi eyodwa, izindleko zezesekeli zisephansi kunezesikulufu esisodwa.

⑩ Izindleko zokukhiqiza ziphansi. Ngenxa yokuzinza okuhle kokusebenza kwemodeli yezikulufo ezimbili, kunezindleko ezimbalwa zokuqala, imfucuza yamanzi negesi incane, izindleko zabasebenzi zincane, ukusebenza kahle kokudlulisa ukushisa okuphezulu, isivuno esikhulu, kanye nezinkomba zokukhipha ugesi ophezulu enkambisweni yokucubungula ukudla. Ngaphezu kwalokho, izindleko zezesekeli nazo ziphansi, futhi izindleko zokugcina zokukhiqiza zisephansi kakhulu uma kuqhathaniswa nesikulufo esisodwa.

Kungenxa yezinzuzo eziningi zezikulufo ezimbili uma kuqhathaniswa nesikulufo esisodwa ekukhiqizeni ukudla kwasemanzini okwenza sikhuthaze ukukhethwa kwesikulufo ezimbili esikhipha izikulufo ezimbili uma izimo zivuma kuzo zonke izici.

Nazi izinyathelo zokuphepha okufanele zithathwe uma usebenzisa i-extruder enama-screw amabili:

1. Ukuphepha kokusebenza:

-Ngaphambi kokusebenzisa i-extruder yezikulufo ezimbili, kubalulekile ukujwayelana nezinqubo zokusebenza kwemishini, izinyathelo zokuphepha, kanye nokusetshenziswa kwamadivayisi okuvala okuphuthumayo.

-Abasebenzi kufanele bagqoke imishini yokuzivikela efanele ukuze bagweme izingozi kanye nokulimala okungenzeka ngesikhathi sokusebenza.

-Qinisekisa ukuphepha kwendawo yokusebenza ezungeze imishini futhi uvimbele izingozi ezifana nokushelela nokushayisana.

2. Ukulungiswa kwemishini:

-Londoloza futhi ulondoloze njalo i-twin screw extruder, okuhlanganisa ukuhlanza, ukugcoba, ukuqinisa amabhawodi, njll. Qinisekisa ukuthi imishini isesimweni esihle sokusebenza.

-Hlola njalo izingxenye eziguga kalula njengezikulufo, ama-washer, kanye nezinsimbi, bese uzishintsha ngesikhathi esifanele ukuqinisekisa ukusebenza okuvamile kwemishini.

-Thuthukisa izinhlelo zokulungisa ezihambisanayo ngokusekelwe ezikhathini zokusetshenziswa kwemishini kanye nendawo yokusebenza ukuqinisekisa ukusebenza okuzinzile kwesikhathi eside kwemishini.

3. Ukuzivumelanisa nezimo kwezinto zokusetshenziswa:

-Imishini yokufutha izikulufo ezimbili inezidingo eziphezulu zezinto zokusetshenziswa, futhi izinto zokusetshenziswa ezahlukene zingadinga amapharamitha enqubo yokufutha ahlukene kanye nezindlela zokusebenza.

-Uma ukhetha imishini, kubalulekile ukuqinisekisa ukuthi imodeli kanye nezincazelo zemishini zifanele ubuchwepheshe bokucubungula obudingekayo ngokusekelwe ezicini zezinto zokusetshenziswa kanye nezidingo zokucubungula.

4. Ukulawula izinga lokushisa kanye nesivinini:

-Izinga lokushisa kanye nesivinini sokujikeleza kuyimingcele ebalulekile ethinta umphumela wokucubungula we-twin screw extruder, futhi idinga ukulungiswa nokulawulwa okufanele.

-Ukulawulwa kwezinga lokushisa kufanele kulungiswe ngokwezinto zokusetshenziswa ezahlukene kanye nezidingo zokucubungula. Izinga lokushisa elidlulele lingaholela ekuvuthweni ngokweqile noma ekushisweni kwezinto zokusetshenziswa, okuthinta ikhwalithi yomkhiqizo.

-Ukulawulwa kwesivinini sokujikeleza nakho kudinga ukulungiswa ngokufanele ngokusekelwe ezintweni zokusetshenziswa kanye nezidingo zokucubungula. Isivinini sokujikeleza esiphezulu noma esiphansi singathinta umphumela wokucubungula kanye nekhwalithi yomkhiqizo.

5. Ubuningi bezinto ezibonakalayo kanye nokulawulwa kwenqubo:

-Ukulawulwa kobuningi bezinto zokwakha kudinga ukulungiswa ngokwezincazelo zemishini kanye nezici zezinto zokwakha. Ubuningi bezinto zokwakha obuningi bungabangela ukuvaleka kwemishini, kanti ubuningi bezinto zokwakha obuphansi kakhulu bunganciphisa ukusebenza kahle kokucubungula.

-Ukulawulwa kwenqubo kudinga ukuhlelwa okunengqondo kokulandelana kokudla nokukhipha izinto zokusetshenziswa, ukuqinisekisa ukusatshalaliswa okufanayo kwezinto zokusetshenziswa kanye nokukhishwa okuvamile komkhiqizo, kanye nokugwema ukuvaleka nokuxubana kwezenzakalo.

6. Ukuhlanza kanye nokuhlanzeka:

-Uma usebenzisa i-extruder enama-screw amabili, kufanele kuqashelwe ukuhlanzeka nokuphathwa kwenhlanzeko kwemishini, futhi kufanele kuhlanzwe njalo izinsalela nothuli ngaphakathi kwemishini ukuze kuvinjelwe ukungcola okuhlukahlukene nokukhula kwamagciwane.
