Izikhwama zepulasitiki, ezake zathathwa njengento entsha ngeminyaka yawo-1970, namuhla ziyinto etholakala yonke indawo etholakala kuwo wonke amagumbi omhlaba. Izikhwama zepulasitiki zikhiqizwa ngesivinini esifinyelela ku-trillion eyodwa njalo ngonyaka. Izinkulungwane zezinkampani zepulasitiki emhlabeni wonke zenza amathani ezikhwama zepulasitiki ezisetshenziswa kakhulu ukuthenga ngenxa yobulula bazo, izindleko eziphansi, kanye nokuba lula kwazo.
Udoti wezikhwama zepulasitiki udala ukungcola ngezindlela ezihlukahlukene. Idatha eminingi ehlukene ibonisa ukuthi izikhwama zepulasitiki zingcolisa indawo ezungezile futhi zilimaza impilo yabantu neyezilwane ezindaweni zasemadolobheni nezasemaphandleni. Olunye udaba ukulahleka kobuhle bemvelo futhi okuhambisana nemfucuza yepulasitiki ukufa kwezilwane ezifuywayo nezasendle. Lokhu kungase kube ngenxa yokungaphathwa kahle kwemfucuza kanye/noma ukungaqondi kahle ngemiphumela eyingozi yezikhwama zepulasitiki.
Ukukhathazeka okwandayo ngomthelela wezikhwama zepulasitiki emvelweni nakwezolimo kuholele ekutheni ohulumeni abaningi bazivimbele. Kubalulekile ukudambisa ubunzima obuphathelene nemfucuza yezikhwama zepulasitiki ngoba izimpahla zemakethe phambilini beziphathwa ngephepha, ukotini, nobhasikidi bomdabu. Uketshezi lwalugcinwa ezitsheni ze-ceramic nezingilazi. Abantu kufanele baqeqeshwe ukuthi bangasebenzisi izikhwama zepulasitiki esikhundleni sendwangu, imicu yemvelo, nezikhwama ze-cellophane.
Manje sisebenzisa i-cellophane ngezindlela eziningi - ukugcinwa kokudla, ukugcinwa, ukwethulwa kwezipho, nokuthuthwa komkhiqizo. Iyakwazi ukumelana namagciwane noma amagciwane ngokuvamile, umoya, umswakama, ngisho nokushisa. Lokhu kuyenza ibe inketho yokuya kuyo yokupakisha.
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.
Yiziphi izinzuzo ze-cellophane?
1.Ukupakishwa okunempilo kwezinto zokudla kuphakathi kwezikhwama eziphezulu ze-cellophane ezisetshenziswayo. Njengoba zigunyazwe yi-FDA, ungagcina ngokuphephile izinto ezidliwayo kuzo.
Bagcina ukudla kusha isikhathi eside ngemva kokuvalwa kokushisa. Lokhu kubalwa njengenzuzo yezikhwama ze-cellophane ngoba zandisa impilo yeshalofu yomkhiqizo ngokuzivimbela emanzini, ukungcola, nothuli.
2.Uma unesitolo sobucwebe, udinga uku-oda izikhwama ze-cellophane ngobuningi ngoba zizoba usizo kuwe!Lezi zikhwama ezicacile zilungele ukugcina izinto ezincane zobucwebe esitolo sakho. Ziyazivikela ezinhlayiyeni zokungcola nezintuli futhi zivumela ukuboniswa kwezinto ezinhle kumakhasimende.
Izikhwama ze-3.Cellophane zilungele ukusetshenziselwa ukugcinwa ngokuphepha kwezikulufu, amantongomane, amabhawodi, namanye amathuluzi. Ungenza amaphakethe amancane kuwo wonke usayizi nesigaba samathuluzi ukuze uwathole kalula lapho edingeka.
4.Enye yezinzuzo zezikhwama ze-cellophane ukuthi ungakwazi ukugcina amaphephandaba kanye neminye imibhalo kuzo ukuze uwagcine kude namanzi. Nakuba izikhwama zamaphephandaba ezizinikele ziyatholakala kwa-Bags Direct USA, uma kunesimo esiphuthumayo, izikhwama ze-cellophane zizosebenza njengenketho enhle.
5.Ukuba yi-lightweight kungenye inzuzo yezikhwama ze-cellophane ezinganakwa! Ngalokho, bathatha isikhala esincane endaweni yakho yokugcina. Izitolo zokuthengisa zifuna izinto zokupakisha ezingasindi futhi ezithatha indawo encane, ngakho-ke, izikhwama ze-cellophane zifeza zombili izinjongo zabanikazi bezitolo zokudayisa.
6.Ukutholakala ngenani elithengekayo nakho kuwela ngaphansi kwezinzuzo zezikhwama ze-cellophane. Kwa-Bags Direct USA, ungazitholela lezi zikhwama ezicacile ngobuningi ngamanani anengqondo amangalisayo! Awudingi ukukhathazeka mayelana nenani lezikhwama ze-cellophane e-USA; uma ufuna ukuwa-oda nge-wholesale, vele uchofoze kusixhumanisi esinikeziwe bese ufaka i-oda lakho ngokushesha!
Ububi Bezikhwama Zepulasitiki
Imfucumfucu yezikhwama zepulasitiki ibeka engcupheni impilo yabantu neyezilwane ngoba ijikijelwa ezindaweni zokulahla imfucuza emhlabeni wonke, ithatha amathani esikhala futhi ikhiphe ukukhishwa kwe-methane ne-carbon dioxide eyingozi, kanye nokuvuza okuyingozi kakhulu.
Ngenxa yokuthi izikhwama zepulasitiki zithatha isikhathi eside ukuhlakazeka, zilimaza imvelo. Izikhwama zepulasitiki ezomiswe ngelanga zikhiqiza ama-molecule ayingozi, futhi ukuwashisa kukhiphela izakhi ezinobuthi emoyeni, okubangela ukungcola.
Izilwane zivame ukwenza iphutha lokuthi izikhwama ziwukudla bese zizidla futhi zingase zibhajwe kumapulasitiki bese iminza. Ipulasitiki
ziya ngokuya zitholakala yonke indawo ku-ecosystem yasolwandle, okudinga ukuthi kuthathwe isinyathelo esisheshayo ezindaweni ezihlala olwandle namanzi ahlanzekile kamuva nje kugqanyiswe njengento ekhathaza umhlaba wonke.
Ipulasitiki yasogwini evalelekile ilimaza umkhumbi, amandla, ukudoba, kanye nezilwane zasemanzini. Izikhwama zepulasitiki olwandle ziyinkinga enkulu yezemvelo emhlabeni wonke. Ukwenyuka kokungcola okuvela ekucutshungulweni noma emithonjeni engcolisa umoya. Izithako ezivuzayo ezikhwameni zepulasitiki ziye zaxhunyaniswa nokwanda kobuthi.
Izikhwama zepulasitiki zisongela kokubili impilo yasolwandle nezolimo. Ngenxa yalokho, izikhwama zepulasitiki ziye zaqeda imithombo yomhlaba edingekayo ngokungazi, kuhlanganise nowoyela. Ukukhiqizwa kwemvelo nezolimo kusengcupheni. Izikhwama zepulasitiki ezingadingeki emasimini zilimaza ezolimo, zibangele ukuwohloka kwemvelo.
Izikhwama zepulasitiki kufanele zivalwe emhlabeni wonke futhi esikhundleni sazo kufakwe ezinye izinto ezibolayo ngenxa yazo zonke lezi zizathu futhi izikhwama ze-cellophane ziyindlela ehlukile yokuba ne-eco-friendly.
Izinzuzo Zokusebenzisa Izikhwama Ze-Cellophane
Nakuba ukupakishwa kwe-cellulose kuyinkimbinkimbi, izikhwama ze-cellulose zinezinzuzo eziningi phezu kwezikhwama zepulasitiki. Ngaphandle kokuba esikhundleni sepulasitiki, i-cellophane inezinzuzo eziningana zemvelo.
- I-Cellophane ingumkhiqizo osimeme owenziwe ngezinto ezisekelwe ku-bio, ezivuselelekayo njengoba wenziwa nge-cellulose etholakala ezitshalweni.Ukupakishwa kwefilimu ye-Cellulose kungabola.
- I-biodegrade ye-cellulose yokupakishwa engafakwanga ishintsha phakathi kwezinsuku ezingama-28-60, kanti ukupakishwa okuhlanganisiwe kuthatha phakathi kwezinsuku ezingama-80-120. Ibhubhisa emanzini ezinsukwini ezingu-10, futhi uma imboziwe, ithatha cishe inyanga.
- I-Cellophane ingase yenziwe umquba ekhaya futhi ayidingi indawo yokuthengisa.
- I-Cellophane ayibizi uma iqhathaniswa nezinye izindlela zepulasitiki ezinobungani bemvelo, okuwumkhiqizo wemboni yephepha.
- Izikhwama ze-cellophane ezibolayo ziyakwazi ukumelana nomswakama kanye nomhwamuko wamanzi.
- Izikhwama ze-Cellophane inketho enhle kakhulu yokugcina izinto zokudla. Lezi zikhwama zilungele izimpahla ezibhakiwe, amantongomane, nezinye izinto ezinamafutha.
- Izikhwama ze-Cellophane zingavalwa kusetshenziswa isibhamu sokushisa. Ungakwazi ukufudumeza, ukukhiya futhi uvikele ukudla ezikhwameni ze-cellophane ngokushesha nangempumelelo ngezinsimbi ezifanele.
Umthelela Wokubola Kwesikhwama Se-Cellophane Emvelweni
I-Cellophane, eyaziwa nangokuthi i-cellulose, iyinhlaka yokwenziwa yamaketanga amade e-glucose ama-molecule abola abe ushukela olula. Emhlabathini, la ma-molecule ayamuncwa. Amagciwane asenhlabathini adiliza la maketango ngenxa yokudla kwawo i-cellulose.
Kafushane nje, i-cellulose ibola ibe amangqamuzana kashukela ama-microorganisms asenhlabathini angase avele awadle futhi awagaye. Ngenxa yalokho, ukuwohloka kwezikhwama ze-cello akunawo umthelela emvelweni noma ezinhlobonhlobo zezinto eziphilayo.
Le nqubo yokubola kwe-aerobic, nokho, ikhiqiza i-carbon dioxide, ekwazi ukuphinda isetshenziswe futhi ayigcini njengomkhiqizo olahlwayo. Phela, i-carbon dioxide iyigesi ebamba ukushisa ebangela ukufudumala kwembulunga yonke.
