Ifilimu ye-Cellophane
I-Cellophane ifilimu elincanyana, elisobala nelicwebezelayo elenziwe nge-cellulose evuselelwe.Ikhiqizwa kusuka ku-pulp yokhuni eqoshiwe, ephathwa nge-caustic soda.Okubizwa ngokuthi i-viscose kamuva kukhishwa kubhavu ye-dilute sulfuric acid ne-sodium sulfate ukuze kuvuselelwe i-cellulose.Ngemuva kwalokho iyagezwa, ihlanzwe, ifakwe i-bleach futhi yenziwe ngepulasitiki nge-glycerin ukuvimbela ifilimu ukuthi ingabi brittle.Ngokuvamile i-coating efana ne-PVDC isetshenziswa ezinhlangothini zombili zefilimu ukuze kunikeze umswakama ongcono nokuvimbela igesi nokwenza ukushisa kwefilimu kuvaleke.
I-cellophane ehlanganisiwe inokungeneka okuphansi kumagesi, ukumelana kahle namafutha, ama-greases, namanzi, okuyenza ifanele ukupakishwa kokudla.Iphinde inikeze umgoqo womswakama omaphakathi futhi ingaphrintwa ngesikrini esijwayelekile nezindlela zokuphrinta ze-offset.
I-Cellophane iyakwazi ukugaywa kabusha ngokuphelele futhi ibolakeke endaweni yokwenza umquba wasekhaya, futhi izophuka emasontweni ambalwa nje.
ifilimu ye-cellophane ekhanyayo
I-Cellophane indalaumkhiqizo wokupakisha obala,i-cellophane isetshenziselwa ukupakisha kuphi?Njengamakhukhi, amaswidi, namantongomane.Yaqala ukumakethwa e-United States ngo-1924, i-cellophane kwakuyifilimu enkulu yokupakisha eyasetshenziswa kuze kube ngama-1960s.Emakethe yanamuhla ekhathalela kakhulu imvelo, i-cellophane ibuya ngokuduma.NjengobaI-cellophane i-biodegradable engu-100%., ibonwa njengendlela ehlukile yomhlaba kunezinye ezisongayo ezikhona.I-Cellophane futhi inesilinganiso somhwamuko wamanzi esimaphakathi kanye nokusebenza kahle kakhulu nokuvala ukushisa, okwengeza ekudumeni kwayo kwamanje emakethe yokugoqa ukudla.
I-cellophane yenziwa kanjani futhi yenziwe ngani i-cellophane?Njengabakhiqizi be-cellophane &i-membrane，Nginomthwalo wemfanelo omkhulu ukunazisa.Ngokungafani namapholymer enziwe abantu kumapulasitiki, atholakala kakhulu ku-petroleum, i-cellophane iyi-polymer yemvelo eyenziwe nge-cellulose, ingxenye yezitshalo nezihlahla.I-Cellophane ayenziwe ngezihlahla zehlathi lemvula, kodwa kunalokho ngezihlahla ezifuywayo futhi ezivunwa ngokukhethekile ukukhiqizwa kwe-cellophane.
I-Cellophane yenziwa ngokugaya izinkuni kanye nezigaxa zikakotini ochungechungeni lwamakhemikhali okugeza asusa ukungcola futhi aphule amaketanga amade e-fiber kule nto eluhlaza.Ivuselelwe njengefilimu ecacile, ecwebezelayo, enamakhemikhali epulasitiki engezwe ukuze kube lula, i-cellophane isakhiwa ikakhulukazi ama-molecule e-crystalline cellulose.
Lokhu kusho ukuthi ingahlakazwa yizinto eziphilayo ezincane ezisemhlabathini njengoba kunjalo namaqabunga nezitshalo.I-Cellulose ingeyesigaba sezinhlanganisela ezaziwa ku-organic chemistry njengama-carbohydrates.Iyunithi eyisisekelo ye-cellulose yi-molecule ye-glucose.Izinkulungwane zala ma-molecule eglucose ahlanganiswa emjikelezweni wokukhula kwezitshalo ukuze kwakheke amaketanga amade, abizwa nge-cellulose.Lawa maketango wona aphulwa ohlelweni lokukhiqiza ukuze akhe ifilimu ye-cellulose esetshenziswa ngendlela engamboziwe noma ehlanganiswe emaphaketheni.
Lapho ingcwatshwa, ifilimu ye-cellulose engagcotshiwe ngokuvamile itholakala ukuthi yonakala ngaphakathiIzinsuku eziyi-10 kuye kwezingama-30;Ifilimu ehlanganiswe ne-PVDC itholakala inciphaIzinsuku ezingama-90 kuye kweziyi-120kanye ne-nitrocellulose-coated cellulose itholakala ukuthi iyanciphaIzinsuku ezingama-60 kuye kwezingama-90.
Ukuhlola kubonise ukuthi isilinganiso sesikhathi esiphelele sokuwohloka okuphelele kwefilimu ye-cellulose sisukaIzinsuku ezingama-28 kuye kwezingama-60ngemikhiqizo engagcotshiwe, futhi kusukelaIzinsuku ezingama-80 kuye kweziyi-120ngemikhiqizo ye-cellulose ehlanganisiwe.Emanzini echibi, izinga le-bio-degradation liyi-izinsuku ezingu-10yefilimu engagqotshiwe futhiizinsuku ezingu-30ngefilimu ye-cellulose eboshwe.Ngisho nezinto okucatshangwa ukuthi zonakala kakhulu, njengephepha namaqabunga aluhlaza, kuthatha isikhathi eside ukuwohloka kunemikhiqizo yefilimu ye-cellulose.Ngakolunye uhlangothi, amapulasitiki, i-polyvinyl chloride, i-polyethene, i-polyethlene terepthatlate, ne-oriented-polypropylene ayibonisi cishe uphawu lokuwohloka ngemva kwesikhathi eside sokungcwatshwa.

Izinzuzo ezi-5 zefilimu ye-cellophane ephrintiwe ngokwezifiso
imibuzo ejwayelekile ukubuzwa
i-cellophane, ifilimu elincanyana le-cellulose evuselelwe, ngokuvamile esobala, esetshenziswa ngokuyinhloko.njengento yokupakisha.Eminyakeni eminingi ngemva kweMpi Yezwe I, i-cellophane yayiwukuphela kwefilimu yepulasitiki eguquguqukayo, esobala eyayitholakala ukuze isetshenziswe ezintweni ezivamile njengokugoqa ukudla ne-adhesive tape.
I-Cellophane yenziwe ngenqubo eyinkimbinkimbi.I-cellulose yokhuni noma eminye imithombo ichithwa ku-alkali ne-carbon disulfide ukuze kwakhe isixazululo se-viscose.I-viscose ikhishwa ngembobo ebhavini le-sulfuric acid ne-sodium sulfate ukuze iguqule i-viscose ibe yi-cellulose.
Ukugoqa kwepulasitiki—njengesembozo esisetshenziselwa ukulondoloza okusalile—kuyanamathela futhi kuzwakala njengefilimu.I-Cellophane, ngakolunye uhlangothi, ishubile futhi iqinile ngokuphawulekayo ayinawo amakhono okubambelela.
I-Cellophane isineminyaka engaphezu kwe-100 ikhona kodwa kulezi zinsuku, umkhiqizo abantu abaningi abawubiza ngokuthi i-Cellophane empeleni i-polypropylene.I-Polypropylene i-thermoplastic polymer, eyatholwa ngengozi ngo-1951, futhi kusukela ngaleso sikhathi isibe ipulasitiki yokwenziwa yesibili ekhiqizwa kabanzi emhlabeni.
I-Cellophane inezakhiwo ezithile ezifana nepulasitiki, okwenza kube inketho ekhangayo ezinkampanini ezifuna ukuphuma ngaphandle kwepulasitiki.Mayelana nokulahlwai-cellophane ngokuqinisekile ingcono kunepulasitiki, nokho ayizifanele zonke izinhlelo zokusebenza.I-Cellophane ayikwazi ukugaywa kabusha, futhi ayivimbeli amanzi ngo-100%.
I-Cellophane ishidi elincanyana, elisobala elenziwe nge-cellulose evuselelwe.Ukungenwa kwawo kancane emoyeni, emafutheni, kugrisi, kumagciwane, nasemanzini ayiketshezi kukwenza kube usizo ekufakweni kokudla.
I-Cellophane membranes iyingxenyeikhiqize kabusha ulwelwesi lwe-cellulose obala lwe-hydrophilicity ephezulu, izici ezinhle zokusebenza, kanye nokubola kwe-biodegradability, i-biocompatibility, nezinhlamvu zokuvimbela igesi.I-crystallinity kanye ne-porosity ye-membrane kulawulwa ngezimo zokuvuselela emashumini eminyaka adlule.
Uma ubheka engilazini eluhlaza, yonke into ibonakala iluhlaza.I-cellophane eluhlaza izovumela ukukhanya okuluhlaza ukuthi kudlule kuyo.I-cellophane imunca eminye imibala yokukhanya.Isibonelo, ukukhanya okuluhlaza ngeke kudlule ku-cellophane ebomvu.
Ukugoqa kwepulasitiki—njengesembozo esisetshenziselwa ukulondoloza okusalile—kuyanamathela futhi kuzwakala njengefilimu.I-Cellophane, ngakolunye uhlangothi, ishubile futhi iqinile ngokuphawulekayo ayinawo amakhono okubambelela.
Ngenkathi zombili zisetshenziselwa ukupakisha ukudla, izinhlobo ze-cellophane zokudla nokugoqa kwepulasitiki zisetshenziswa zihlukile.
Cishe uke wayibona i-cellophane egoqwe amaswidi, izinto ezibhakwayo, ngisho namabhokisi ambozekile wetiye.Iphakheji inomswakama ophansi kanye nokungena komoya-mpilo okwenza kube kuhle ekugcineni izinto zizintsha.Kulula kakhulu ukudabula nokukhipha kunokugoqa ngepulasitiki.
Ngokuqondene nokugoqa kwepulasitiki, kungenza ukudla kube lula ngenxa yokunamathela kwayo, futhi ngenxa yokuthi kuyathandeka, kunganela izinto ezihlukahlukene.Ngokungafani ne-cellophane, kunzima kakhulu ukudabula nokukhipha emikhiqizweni.
Khona-ke, kukhona lokho enziwe ngakho.I-Cellophane itholakala emithonjeni yemvelo efana nokhuni futhi iyakwazi ukubola futhi ingafakwa umquba.Ukugoqa kwepulastiki kwenziwa nge-PVC, futhi akuboli, kodwa kugaywa kabusha.
Manje, uma kwenzeka udinga okuthile ukuze ugcine okusele kwakho, uzokwazi ukucela ukugoqwa kwepulasitiki, hhayi i-cellophane.
Ifilimu ye-cellophane isobala, ayinabo ubuthi futhi ayinambitheki, imelana nokushisa okuphezulu futhi ibonakala.Ngenxa yokuthi umoya, uwoyela, amagciwane, namanzi akungeneki kalula ngefilimu ye-cellophane, kungasetshenziselwa ukupakisha ukudla.
Njengamabizo umehluko phakathi kwe-cellophane ne-clingfilmis ukuthi i-cellophane ingenye yezinhlobonhlobo zamafilimu epulasitiki asobala, ikakhulukazi elenziwe nge-cellulose ecutshungulwayo ngenkathi i-clingfilm iyifilimu encane yepulasitiki esetshenziselwa ukugoqa ukudla njll;U-Saran Wrap.
Njengesenzo se-cellophaneis ukugoqa noma ukupakisha ku-cellophane.
