Imibuzo ebuzwa qho
i-cellophane, ifilimu ecekethekileyo yeselulosi ehlaziyiweyo, ihlala icaca, isetyenziswa ikakhulu.njengempahla yokupakisha.Kangangeminyaka emininzi emva kweMfazwe Yehlabathi I, icellophane yayikuphela kwefilimu yeplastiki ebhetyebhetye necacileyo ekhoyo ukuze isetyenziswe kwizinto eziqhelekileyo ezinjengokusongelwa kokutya neteyiphu yokuncamathelisa.
I-Cellophane yenziwe ngenkqubo entsonkothileyo.I-cellulose evela kumthi okanye eminye imithombo iyachithwa kwi-alkali kunye ne-carbon disulfide ukwenza isisombululo se-viscose.I-viscose ikhutshwe nge-slit kwibhafu ye-sulfuric acid kunye ne-sodium sulfate ukuguqula i-viscose ibe yi-cellulose.
Iplastiki yokugoqa-njengesigubungelo esisetyenziselwa ukugcina izinto ezisele-iyancamathela kwaye ivakalelwa ngakumbi njengefilimu.I-Cellophane, kwelinye icala, ingqindilili kwaye iqinile ngokuphawulekayo ayinakho ukubambelela.
I-Cellophane ikhona iminyaka engaphezu kwe-100 kodwa kwezi ntsuku, imveliso abantu abaninzi abayibiza ngokuba yi-Cellophane ngokwenene yi-polypropylene.I-Polypropylene yipolymer ye-thermoplastic, eyafunyanwa ngengozi ngo-1951, kwaye ukusukela ngoko ibeyeyesibini iplastiki eyenziwe ngokubanzi emhlabeni.
I-Cellophane ineempawu ezifana neplastiki, nto leyo eyenza ukuba ibe yinto enomtsalane ngakumbi kwiimpawu ezifuna ukuya ngaphandle kweplastiki.Ngokwemiqathango yokulahlwaI-cellophane ngokuqinisekileyo ingcono kuneplastiki, nangona kunjalo ayifanelekanga kuzo zonke izicelo.I-Cellophane ayinakurisayikilishwa, kwaye ayikhuseli manzi nge-100%.
I-Cellophane liphepha elincinci, elicacileyo elenziwe nge-cellulose ehlaziyiweyo.Ukungenwa kwayo okuphantsi emoyeni, kwi-oyile, kwiigrisi, kwiibhaktheriya, nakumanzi alulwelo kuyenza ibe luncedo ekupakishweni kokutya.
Cellophane inwebu ziihlaziywe ngokutsha iimembrane zeselulosi elubala ze-hydrophilicity ephezulu, iipropathi ezilungileyo zoomatshini, kunye ne-biodegradability, biocompatibility, kunye neempawu zesithintelo segesi.I-crystallinity kunye ne-porosity ye-membrane iye yalawulwa ngeemeko zokuvuselela kwiminyaka edlulileyo.
Ukuba ujonga ngeglasi eluhlaza, yonke into ibonakala iluhlaza.I-cellophane eluhlaza iya kuvumela ukukhanya okuluhlaza ukuba kudlule kuyo.I-cellophane ifunxa eminye imibala yokukhanya.Ngokomzekelo, ukukhanya okuluhlaza akuyi kudlula kwi-cellophane ebomvu.
Iplastiki yokugoqa-njengesigubungelo esisetyenziselwa ukugcina izinto ezisele-iyancamathela kwaye ivakalelwa ngakumbi njengefilimu.I-Cellophane, kwelinye icala, ingqindilili kwaye iqinile ngokuphawulekayo ayinakho ukubambelela.
Ngelixa zombini zisetyenziselwa ukupakishwa kokutya, iintlobo ze-cellophane yokutya kunye nokusonga kweplastiki zisetyenziswa zahlukile.
Mhlawumbi ukhe wayibona i-cellophane ijikelezwe ngeelekese, izinto ezibhakiweyo, kunye neebhokisi zeeti.Ipakethe inokufuma okuphantsi kunye nokungena kweoksijini okwenza kube kuhle ukugcina izinto zintsha.Kulula kakhulu ukukrazula nokususa kunosongelo lweplastiki.
Ngokuphathelele ukusonga ngeplastiki, kunokunika ukutya ngokulula itywina eliqinileyo ngenxa yendalo yayo encamathelayo, kwaye ngenxa yokuba ithambile, inokulingana nezinto ezahlukeneyo.Ngokungafaniyo ne-cellophane, kunzima kakhulu ukukrazula kunye nokususa kwiimveliso.
Emva koko, kukho into eyenziwe ngayo.I-Cellophane ithathwe kwimithombo yendalo efana nemithi kwaye i-biodegradable kwaye inokuvundiswa.Ukusonga ngePlastiki kwenziwa kwiPVC, kwaye akunakwenzeka ukubola, kodwa kuyaphinda kusetyenziswe.
Ngoku, ukuba ukhe wafuna into yokugcina okushiyekileyo, uya kukwazi ukucela ukusonga iplastiki, hayi i-cellophane.
Ifilimu ye-cellophane iyabonakala, ayinayo ityhefu kwaye ayinambitheki, iyamelana namaqondo okushisa aphezulu kunye nokungafihli.Ngenxa yokuba umoya, ioli, iibhaktheriya kunye namanzi azingenwa lula ngefilimu yecellophane, zinokusetyenziselwa ukupakisha ukutya.
Njengezibizo umahluko phakathi kwe-cellophane kunye ne-clingfilmis ukuba i-cellophane yiyo nayiphi na iindidi zeefilimu zeplastiki ezicacileyo, ngakumbi enye eyenziwe nge-cellulose esetyenzisiweyo ngelixa i-clingfilm ifilimu yeplastiki ebhityileyo esetyenziselwa ukusongela ukutya njl.Saran Wrap.
Njengesenzi se-cellophaneis ukusonga okanye ukupakisha kwi-cellophane.
