Ukukhiqizwa kwe-polypropylene izikhwama: ubuchwepheshe kanye nemishini

Njengoba nokwenza kahle izinqubo yezimboni womshini imikhiqizo ziyahlukahluka futhi lisondela enhlanganweni yabo lobuchwepheshe. Isicelo imishini compact ingasetshenziswa isikhala esincane phansi ephazamisa kukuthenga izindleko zokukhiqiza. Lo mkhuba maqondana ukuhleleka ngenkathi iqinisekisa ukuthi umkhiqizo yokukhiqiza inqubo Into ephawuleka kakhulu emikhakheni ukukhonza izidingo zasekhaya. Ngakho, ukukhiqizwa kwe-polypropylene izikhwama eligxile izilaleli ebanzi abathengi, phakathi okuyinto Nokho, abathengi abavamile nje kuphela kodwa futhi amabhizinisi ezinkulu. Lokhu kuholela ingxenye nasithakazelo ingxenye amabhizinisi amancane, kubalulekile ukuvula siqu abazokusho ukukhiqizwa.

Kuyini esikhwameni polypropylene?

Lolu hlobo izikhwama ukupakisha, injongo okuyinto kungase kubhekwe njengokwelapha jikelele. Noma kunjalo, endaweni eyinhloko isicelo imikhiqizo enjalo kuyehla kube ukusetshenziswa ekhaya - njengoba umthetho, ziqukethe izinto okuxekethile, amamiksi owomile, fillers ukusuthisa, njll isikhwama polypropylene esetshenziselwa isitoreji kwezimpahla ze-non-ukudla. Ngisho embonini yezokwakha kwenza bekholelwa ukuthi ngabe iphakheji enjalo ukugcina ahambise usimende, amalahle, imisindvo ahlukahlukene nemfucumfucu.

Kuye uhlobo yokukhiqiza inqubo sisetshenziswa manje, umkhiqizo sinikezwe kwalokho noma ezinye izici. Ngokwesibonelo, ukukhiqizwa kwe-polypropylene izikhwama eRussia muva ngenkuthalo ekuthuthukiseni ubuchwepheshe kwezicubu conductive. Siyabonga lekucamba okunezinhlobonhlobo kuvuselela izikhwama conductive futhi antistatic. Ngokuphathelene isici eyinhloko ikhono ukubhekana imithwalo, le polypropylene ejwayelekile igxile isisindo 5.10 kg. izikhwama Akhethekile enkulu namandla okuzabalaza kg 50 noma ngaphezulu, kodwa imikhiqizo enjalo ngokuvamile ekhiqizwa ngokuvumelana oda angawodwana.

izigaba kwezobuchwepheshe zokukhiqiza

Inqubo iqala ukulungiswa impahla eluhlaza kuyiphi base senziwa ngemuva kwalokhu tekwakha izikhwama. I plastic sokuqala okuxubile yomiswa yamathebhu granules. Ngenxa yezizathu umnotho, futhi ebavumela ukukhiqizwa kwe-polypropylene izikhwama kabusha, okungase exutshwa isisekelo ecacile, ngemva kwalokho ingxube yabekwa staining futhi buhlanjululwe izithasiselo ukulungisa.

Isigaba esilandelayo ukondla mass okulungiselelwe kuya extruder lapho ukufuthelana 260 ° C. Waba yini umphumela walesi sinyathelo yinqubo ukwakha lokuluhlaza flat. Izindlela ukusika futhi iyapholisa ubuchwepheshe evumela usayizi elilungile kuya akha imicu oluyisicaba ukuze plexus izikhwama esizayo.

Ukudala isizinda ndwangu okuthiwa i-uhlaka lokweluka indwangu isiyingi, okuyinto ukukhiqiza emkhonweni ngu emazombezombe Imicu yotshani nokwelukiweyo ku esondweni ekhethekile. Isinyathelo sokugcina ahlabayo of siphelile Indwangu base banikezwe Ubukhulu nemithungo impahla ku imikhiqizo isiqedile. Kubonakala sengathi i-ukukhiqizwa zakudala kwe-polypropylene izikhwama. Ubuchwepheshe kanye nempahla kungahle futhi kufakwe ezinye izici inqubo, ngenxa yezimfuneko yekhasimende. Ngokwesibonelo, njengoba isinyathelo eyengeziwe okungenzeka owethulwa flexography.

Extrusion Line lokuluhlaza flat

Ukukhiqizwa ngqo impahla kusukela lapho isikhwama wenziwe polypropylene, iqala inqubo extrusion. Ukuze uqale ukuvunwa ingxube efanayo, okuyinto futhi ehambisana ukusebenza edingekayo of umkhiqizo wokugcina. Umugqa ngesisekelo extruder, okuthela ifilimu plastic. onobuhle Iningi sisebenze anhlobonhlobo polymer-based, kodwa noma kunjalo imisebenzi eziyinhloko zihlanganisa Ukushisa, extrusion nemigwalo. Uma ukukhiqizwa eyayibekiwe kwe-polypropylene izikhwama usayizi esikhulu, extruder ekuqaleni amisiwe ukunikeza Imicu yotshani ububanzi obukhulu. Nokho, isinyathelo esilandelayo ikuvumela ukulungisa ifilimu ngesikhathi format oyifunayo.

Ngetulu kwaloko, kusondzela isiyingi

Ukuze kwakhiwe isizinda Indwangu esetshenziswa amayunithi Isiyingi. Nge yokudalwa kwenzeka nge emikhonweni okuqhubekayo kwe-polypropylene. Kukhona izinguqulo eziningana kule imishini, okuyinto zingafani inani shuttles. Ngakho, phakathi inguqulo eyisisekelo kungenziwa okukhulunywa umshini 4-Shuttle. Izinzuzo lokhu umshini inikeza inombolo okungenani izingxenye kuncike ukugqoka, okwenza kube outperforms analogue e ngokuqina. It kwandisa nokwethenjelwa emgqeni jikelele, lapho ukukhiqizwa kwe-polypropylene izikhwama.

Okokusebenza bephethe uhlelo ukudluliswa nge amasondo roller, okuyinto akudingeki Lubrication njalo. Umehluko wemisindo nemiqondo yamagama, esikhundleni salokho, kubangele futhi kalula abebeziphilisa ngako.

Machines ukuzisika nemithungo izikhwama

Cutting engenziwa ngesandla bese athutha. Ngo zezimboni isikali womshini ngokuya usebenzise inketho kuqala. Kulokhu, amayunithi esetshenziswa ukwenza ahlabayo bezikhwama okulungiselelwe zihamba ngesivinini esingamakhilomitha ka imikhono 40-50 izingcezu ngokuzenzakalelayo. Ububanzi esiphezulu yezincwadi, ziyatholakala ukucutshungulwa, ifinyelela 800 mm amafomethi ejwayelekile. Kwezinye izimo, walungisiswa futhi ukukhiqiza ibhukwana polypropylene izikhwama.

Lolu hlobo ukusika ubuchwepheshe kuhilela ukusetshenziswa amatafula ekhethekile lapho inkonzo opharetha, kuhlanganise osayizi angajwayelekile kanye imikhono. Ngemva kwalokho, uma ungena nemishini abathungela lezisekelo ukunquma for izikhwama. Ngokuvamile lokubolekwa ezifana kwakhiwa emphethweni izingqimba engenhla nengezansi indwangu plastic.

Machines flexo

Ukuphrinta enze imishini ekhethekile, olunikezwa inzwa yesithombe. Okuvame kakhulu umshini nezimo kwenza ukuphrinta ku izicubu plastic polyethylene ne-polypropylene. Kwamanye imigqa nazo asetshenziswa offset imishini ukuthi zinezikhathi ikhono lazo ukubeka ezimbili ezintathu-umbala zokunyathelisa. Lokhu yesimanje imishini ephezulu ukucacisa, okuyinto ukulawula lizwakala iphaneli electronic. Ikakhulu, i-ukukhiqizwa kwe-polypropylene izikhwama (isithombe eboniswe ngezansi) kuhilela ukusetshenziswa imishini flexographic yalolu hlobo.

Izimfuneko nemibandela ukukhiqizwa

Kungakhathaliseki indlela yokwakheka entanjeni yokusebenza, ukukhiqizwa kwanoma umnikazi kumele anikeze izimo ezifanele ukusebenza imishini. Kwasekuqaleni, kanye zonke izitolo, ukusebenza okuyinto lihlotshaniswa ukucutshungulwa polymers, imigqa enjalo kumele zisuswe emakhaya. Esikhathini izikhala kakhulu efanayo inikeze ngempumelelo ukupholisa uhlelo lokufeza zokuxhumana ngesimo amapayipi namanzi izifunda, kanye banakekele ukufakwa ukwelashwa amanzi izihlungi.

Njengoba usayizi ekamelweni, ukukhiqizwa kwe-polypropylene izikhwama ngokuvamile eyenziwa ukukhiqiza imigqa endaweni ezingekho ngaphansi kuka-50 m2. Ngakho, ngenxa yokulungiswa kahle ezifana isakhiwo usayizi kwesigaba sabasebenzi kufanele okungenani 80 m2.

isiphetho

Inqubo yokwenza polypropylene izikhwama kudinga ukutshalwa kwezimali ezinkulu enhlanganweni. Rental kwezakhiwo kanye ukuthengwa imishini - kuphela izinto eziyisisekelo ezidinga kukhishwe imali, kodwa esikhathini esizayo kungase kudingeke futhi ukudalwa ezengeziwe inqubo izinyathelo ibhizinisi.

Ngokwesibonelo, ukukhiqizwa ukuncintisana polypropylene izikhwama ezimweni yesimanje kungenzeka kuphela ukuqapha ngokucophelela izinga umkhiqizo. Ngenxa yalokho, edingekayo ngcono kanye isigaba luhlolo imikhiqizo. Futhi uzodinga izimo isitoreji nenhlangano izimpahla. Nakuba izikhwama polypropylene awazithathi eningi isikhala futhi asidingi izimo isitoreji ekhethekile, ukubukeka kwabo kungenziwa spoilt by imiphumela mechanical ngesikhathi yezokuthutha - lokhu futhi akufanele sikhohlwe.
