Nciphisa ifilimu upakisha: incazelo kanye nezinhlobo

Nge ukuthuthukiswa emkhakheni ubuchwepheshe zamakhemikhali ekuthuthukiseni imikhiqizo yayo. umkhakha eside ingxenye kuthiwa ekufakeni izinto, ngawo abakhiqizi nonfood nokudla imikhiqizo ukugcina izindawo zabo kanye nokusebenza. ukuthandwa Omkhulu wathola ifilimu zikhwantabale emabhokisini isithombe okuyinto abekwe ngezansi.

Izici Nciphisa ifilimu

Umehluko oyinhloko Nciphisa ifilimu yikhono layo nciphisa ukuze usayizi elihambisana into target. kokucindezelwa kwalo kwenzeka ngaphansi okushisa aphakeme. Emva lwaluyophola, indaba kuthatha ifomu komkhiqizo ezipakishiwe. Ngakho, ifilimu Nciphisa upakisha Ungagcina izimfanelo lobuchwepheshe nezingokwenyama imikhiqizo ehlukahlukene, kuhlanganise ukwakhiwa nokudla.

Kuye kwenkululeko ukusetshenziswa abakhiqizi futhi ahlinzeke ezinye izici ku ifilimu. Ngokwesibonelo, ifilimu apertured ikhiqizwa imikhiqizo ebhikawozi. Isisekelo ukwaziswa okufanayo eluhlaza izenzo PVC noma zithutha polyolefin. Uma PVC kuyinto ngokuvamile in funa ngenxa ukuqina bayo, POF kunenzuzo ngalolo alinaso ukungcola okuyingozi. Ngokuvamile, ifilimu zikhwantabale amabhodlela isembozo noma iziqukathi ukudla ikhiqizwa material polyolefin.

Isicelo ifilimu

Kuye indices Nciphisa ifilimu futhi ugqinsi ingase isetshenziselwe izinjongo ezihlukahlukene. Ngakho, uma kuyindodana, degree elincane clamping, indaba ingasetshenziswa imikhiqizo ezithambile izicubu, imikhiqizo iphrintwe noma imikhiqizo ukudla. Ngokuphambene, ukuncipha ngendlela elukhuni ivumela ukuphatha zokwakha esindayo, kanye imikhiqizo amafomu angajwayelekile. Okunjalo uyalandisa oluhlehlela ifilimu lokugoqa amapulangwe ehlanganisa iqembu party, ngokuphepha kokuwalungisa sisendleleni. By the way, womshini a ezifana ifilimu polyvinyl chloride sisetshenziswa. Kubalulekile ukwazi ukuthi ngaphezu zokuzivikela futhi ukugcwaliswa umsebenzi ifilimu ingasetshenziswa umklamo okubonakalayo umkhiqizo. Isembozo Nciphisa ngokuvamile zihambisana iphepha lokunamathisela odongeni, amathoyizi, omagazini, enika umkhiqizo ucwebezela ngendlela ekhangayo extra futhi kukhanye.

izici impahla

Le filimu itholakala ngetakhiwo letehlukene, okuyinto ziyahlukahluka kuye umshini emaphaketheni. Ngokuphathelene kukhethwa umkhiqizo othize, kufanele sinake izici ezimbili - iphesenti ukuncipha ukushuba. Ngokuvamile, iphesenti ukuncipha emgqeni longitudinal komyalelo wokungabi 60-70%, futhi esigabeni cross - kusuka 10 kuya 50%. On amandla emaphaketheni inomthelela ukujiya. Le filimu thinnest ngoba Nciphisa emabhokisini wenza ngokuvumelana nezindinganiso yenqubo zobuchwepheshe, has a ukushuba 10 microns. ukuhlukahluka High lingafika microns 200. Ngaphezu kwalokho, kubalulekile ukuba acabangele izimo lokushisa lapho impahla ingasetshenziswa. Isilinganiso ovumelekile lokushisa ephasishi ivela -40 kuya +50 ° C, nakuba kuye inqubo hlelo lokusebenza kungenzeka wengeze izithasiselo ukuthuthukisa leli banga.

izakhiwo yokusebenza

Kukhona iqoqo eziyisisekelo izimfanelo emimoya cishe zonke ukulungiswa shwabanisa amafilimu. Endaweni yokuqala phezulu amandla mechanical kuya ezigunyaza zokuzivikela izinga emaphaketheni. Futhi, lolu hlobo impahla libhekene inhlanganisela eguquguqukayo kanye obala. Ukumelana ekwakhekeni amanzi olujiyile ne umswakama ukumelana futhi ekwandiseni amathuba ukusetshenziswa ifilimu.

Yiqiniso, impahla cishe eyingqayizivele, okuyinto has a ifilimu zikhwantabale emabhokisini yikhono ukushintsha imingcele eqondile futhi uthathe ukuma umkhiqizo target. Enye into ukuthi kudinga izinto ezikhethekile, nokobana kwemibhalo. Kodwa ngo-fit aminyene ezihlangene esizayo uyonika ngokugcwele izinto ezimbili eziwusizo abalulekile. Okokuqala, bazonikezwa isivikelo ukuvulwa, futhi okwesibili, kule nqubo ye ethutha izimpahla ephathini kuzothatha okungenani isikhala. Uma sikhuluma izakhiwo ngabanye, phakathi kwabo kukhona ukuphepha kwemvelo kanye ukubukeka ekhangayo. Lezi izimfanelo esebenza ukuguqulwa olukhethekile umkhiqizo ifilimu.

zinhlobo

Nakuba iningi ifilimu izinto benethuba ukushisa-kulungiselelwa ifana banayo ukungaboni ngaso linye okuningi. Bocwepheshe ihlukaniswa emaphaketheni ngohlobo isakhiwo, ubulukhuni, khona modifiers ezithile e ukwakheka, isayizi, simo, ngakho lolu daba. D. Esinye sezici ezibaluleke kakhulu ukuhlukana uhlobo lwesakhiwo. I elula kunazo ukusebenzisa ubhekwa cross-ifilimu indwangu ezimangelengele. Akukona ukubeka amarekhodi ngokwemigomo amandla, kodwa oyiyo waphawula ibhalansi elilungile lendwangu ukujiya kanye namandla eqine. Le mpahla kubalulekile uma, isibonelo, isetshenziselwa Nciphisa ifilimu isembozo ulwelwesi e omningi. Ngaphambi sikhonza abasebenzi kuleli cala, umsebenzi wokulondoloza esiphezulu esitholakalayo futhi ngesikhathi esifanayo ukuqinisekisa ubuqotho ifilimu uqobo. Mayelana umehluko ukwakheka, bese izinto aqhelelene, aqukethe hydrochloride injoloba, polystyrene, polyamide nokunye okunjalo. D. ngokukhethekile unikezwa ngezigaba ngenani ifilimu izingqimba.

I multilayer futhi monolayer ifilimu

Ukuze uqale, kufanele kuphawulwe ukuthi umehluko eziyisisekelo kunqunywa indlela yokukhiqiza. Single-ungqimba ndwangu ezivezwa indlela extrusion, isb ukuphoqa mass plastic. ngaleyo ndlela Izinzuzo etholwe imikhiqizo kungafaka viscosity anda, kuyaqina, futhi obala. Kodwa uma ukhetha oluhlehlela ifilimu ngoba ukupakisha kwezitini noma ezinye izinto zokwakha, kungcono ubheke nozakwabo multi-ungqimba. a impahla okunjalo kuveza coextrusion imiklamo. Umehluko omkhulu senqubo yokukhiqiza ukuthi ikhanda esikhiqiza extruders ethize esetshenziswa. Multi-Ply web yakhiwa ukwakheka copolymer kanye acid ukulungisa kanye copolymer of ethylene. isakhiwo ifilimu lungaba izingqimba eziningana ezengeziwe.

nokupakisha ukucushwa

ezahlukeneyo ezahlukene womkhiqizo Nciphisa ifilimu, ekukhethweni zazo kunqunywa izici imikhiqizo. Ikakhulukazi, lisebenzisa eyodwa, iqembu kanye emaphaketheni stacked. Inketho yokuqala isetshenziswa ukusebenza izimpahla ucezu - okubizwa ngokuthi emaphaketheni ngabanye. indlela Iqembu lisetshenziswa imishini olulodwa imikhiqizo eziningana izici ezifanayo ntathu. Ngokwesibonelo, ukumisa ezifana ivumela Nciphisa ifilimu ngoba asemaphaketheni Pallets ukuthi pre-embondelene substrate ekhethekile. Ngaphezu ukugcina indlela enjalo emaphaketheni kwenza zokuthutha mnene futhi ephephile kwezimpahla. ukumiswa stacked siphinde sihlinzekele nezinhlelo ezihlanganisa ukusetshenziswa Pallet, kodwa ukuqina ezithuthukisiwe. Lokhu kukhetha efanelekayo ukulawula anhlobonhlobo imikhiqizo: kusukela namakani nezinti amabhuku izitini izikhwama. Ngemva emakhiyubhi izimpahla imbozwe ikhava ifilimu.

Khipha ifomu bese wokugubha

Ulungiselela ifilimu is nilimaza phezu emikhonweni akhethekile iza ngesimo imiqulu. Ngenhla ngamunye emazombezombe nayo imbozwe emgodleni zokuzivikela ezenziwe iphepha noma we polyethylene efanayo. Ngokuvamile, Nciphisa ifilimu wrapper roll has a ububanzi 500 mm nesisindo 35 kg. Nokho, umkhakha kanye nokukhiqiza izinto zokwakha, nezinye izakhiwo, isibonelo nge ububanzi 1000 mm kanye nesisindo 50 kg. roll ngamunye ngempela bamake yilebula okuqukethe ulwazi mayelana nomkhiqizi, ukucacisa komkhiqizo, idethi, njll Uma ukhetha imikhiqizo ifilimu kumele uthole ulwazi mayelana izivivinyo - .. Ulwazi izici nokusebenza namakhono kuzosiza ukuthenga emaphaketheni ngokufanele ofanele izidingo ezithile.

isiphetho

imikhiqizo emaphaketheni emakethe libanzi impela, okuyinto ngenxa nesidingo esikhulu sezindawo imikhiqizo yaleli qembu. Quality emaphaketheni liyadingeka namuhla emikhakheni ehlukahlukene: zokulungisa ukudla ukuze Izitolo okudayisa. Njengoba umkhuba ubonisa ukusetshenziswa ukushisa-Nciphisa izinto, mayelana 90% lokhu ukukhiqizwa isetshenziswa enkonzweni kwezimpahla ze-non-ukudla. Nokho, kukhuphuke ukuphepha kwemvelo kanye nokwenzeka ekwandiseni ukusetshenziswa emaphaketheni for imifino, imikhiqizo ebhikawozi, imikhiqizo Semi-siphelile nokunye. D.

Okuthuthukisiwe Nciphisa ifilimu ngoba asemaphaketheni kwezimpahla ngokulandela nokuphepha. Ukuqina, ukumelana izinyembezi nokuqeda yobunzima - lezi zimfanelo kukhona ezibaluleke kakhulu ekugcinweni zokwakha, zazo -. Wallpaper, izihloko kufaneleka, zama-tile, iphaneli ulwelwesi, njll Futhi, kukhona mkhuba ukukhula kwesidingo okukhethekile amafilimu ukulungiswa anikeze izakhiwo ukusebenza.
