Yonke into oyifunayo ukwazi malunga nokupakishwa kweselfowuni
Ukuba ubukele kwizinto zokupakisha ngokusingqongileyo, amathuba okuvile nge-seluplose, ekwabizwa ngokuba nguCellophane.
UCellophane yimpahla ecacileyo, ecekisekayo ejikeleze ukusukela kwiminyaka yoo-1900s. Kodwa, inokumangalisa ukuba ufunde ukuba uCellophane, okanye ukupakisha ifilimu, kusekwe kwimveliso "eluhlaza".
Yintoni ukupakishwa kweselfowuni?
Ifunyenwe ngo-1833, isellulose yinto efumaneka ngaphakathi kweendonga zeseli. Iqulathe i-chain ende yeemolekyuli zeglucose, ezenza i-polysaccharide (ixesha lesayensi le-carbohydrate).
Xa kukho imixokelelwane ye-seluplose ye-hydrogen bobult, bakha into ebizwa ngokuba yi-microfibrils, ezingenakuthelekiswa nanto kwaye zinzima. Ukungqongqo kwale microfibrils kwenza imolekyuli ebalaseleyo ukuyisebenzisa kwimveliso ye-biobististicisticisticisticisticisticisticisticisticisticisticisticisticisticisticististi.
Ngapha koko, iselpulose yeyona ibaluleke kakhulu kwi-biopolymer enkulu kwilizwe liphela, kwaye amasuntwa ayo anefuthe elincinci lokusingqongileyo. Nangona kukho iindlela ezahlukeneyo zeselselose. Ukupakisha ukutya ukutya kuseseselfowuni kuhlala kuhleli uCellophane, iplastiki ecacileyo, emdaka, yeplastiki efana neplastiki.
Imveliso yokupakisha ifilimu ye-sellwase yenziwe njani?
I-Cellophane idalwe kwi-selsulose ethathwe kwikotoni, iinkuni, ishemp, okanye enye imithombo yendalo ekuzinzileyo. Iqala njenge-pullation ye-white yokuchithwa, eyi-92% -98% yeseluplose. Emva koko, i-row seluplose ipulpul idlula kwezi nyathelo zine zilandelayo zokuguqulwa zibe nguCellophane.
1. I-Selelose ichithwe kwi-alkali (ityuwa esisiseko, i-ionic ye-alkali yentsimbi) kwaye ihluphekile iintsuku ezininzi. Le nkqubo yokuguqula ibizwa ngokuba ngumxube.
2. Ukulahleka kwekharbon kusetyenziswa i-pulp ye-Merp ukwenza isisombululo esibizwa ngokuba yi-Galuplose Xenate, okanye i-viscose.
3. Esi sisombululo sisongezwe kumxube we-sodium ye-sodium kunye ne-diluturic acid. Oku kujika isisombululo sibuyele kwiseluplose.
4. Ke, ifilimu yeselselose ihamba ngeendlela ezintathu. Okokuqala ukususa i-sulfure, emva koko ukubukela ifilimu, kwaye ekugqibeleni ukongeza i-glycerin ukuze isebenze.
Isiphumo sokugqibela nguCellophane, osetyenziswa kumzi-mveliso wepakisi wokutya, ikakhulu ukwenza iingxowa ze-biloegrades okanye "iingxowa zeCello".
Zithini izibonelelo zeemveliso zeselfowuni?
Ngelixa inkqubo yokudala ukupakisha iselfowuni inzima, izibonelelo zicacile.
Abantu baseMelika basebenzisa iingxowa zeplastiki eziyi-100 qho ngonyaka, befuna imiphanda ye-12 yeebhiliyoni zeoyile kunyaka ngamnye. Ngaphandle koko, izilwanyana ezingama-100,000 zaselwandle zabulawa ngeengxowa zeplastiki ngonyaka. Kuthatha ngaphezulu kweminyaka engama-20 yeengxowa zeplastiki ezisekwe kwiPetrole ukuya kuthi ga elwandle. Xa besenza, bavula iiplanga ezincinci ezingena kwikhonkco lokutya.
Njengoko uluntu lwethu lukhula ngakumbi kwindalo esingqongileyo, siyaqhubeka sikhangela ezinye iindlela ze-eco-ezinobuhlobo, ze-biodegrady kwiplastiki esekwe kwiPetroleum.
Ngaphandle kokuba nendlela enye yeplastiki, ukupakisha ifilimu zefilimu kuzisa izibonelelo ezininzi zokusingqongileyo:
Ukuzinza & ngokusekwe
Ngenxa yokuba uCellophane wadalwa kwi-sellutase evunelwa kwizityalo, yimveliso ezinzileyo efakwe kwizibonelelo ezisekwe kwi-bio, ezihlaziyiweyo.
I-biodegraded
Ukupakisha ifilimu ye-selselose ye-selselose i-biodegradad. Iimvavanyo zibonakalise ukuba ukupakisha se-selupelose kwiintsuku ezingama-28-60 ukuba imveliso ingaba le mveliso ingenamali kwaye ingama-2000 kwiintsuku ukuba idityaniswe. Ikwakhupha amanzi emanzini kwiintsuku ezili-10 ukuba ayinamali kwaye ijikeleze inyanga ukuba idityanisiwe.
Phawula
I-Cellophane ikhuselekile ukuba ifake imfumba yakho yomgquba ekhaya, kwaye ayifuni indawo yezorhwebo.
Izibonelelo zokupakisha ukutya:
Ixabiso eliphantsi
Ukupakishwa kweselphuase sele bekujikeleze ukusukela ngo-1912, kwaye kukuveliswa kweshishini lephepha. Xa kuthelekiswa nezinye iindlela zeplastiki ze-eco, uCellophane unendleko eziphantsi.
Ukufuma-ukunganyangeki
Iingxowa ze biellophane zinobuzane
Ukunganyangeki kweoyile
Ngokwemvelo bayamelana ioyile kunye namafutha, ke iingxowa zeCellophane zilungile kwiimpahla eziphekiweyo, amantongomane, kunye nezinye ukutya okunamathela.
Ukutshiswa okuswelekileyo
I-Cellophane ishushu itywina. Ngezixhobo ezifanelekileyo, unokukhawuleza kwaye ngokulula itywina lokukhusela kwaye ukukhusela iimveliso zokutya ezigcinwe kwiingxowa zeCellophane.
Liyintoni ikamva lephakheji yeselfowuni?
Ikamva leIfilimu yeselfowuniUkupakisha kujongeka kukhanya. Ingxelo yexesha elizayo lemarike iqikelela ukupakisha iselfowuni iya kuba nenqanaba lokukhula minyaka le le-4.9% phakathi kuka-2018 nowama-2028.
Iipesenti ezingama-70 zokukhula kulindeleke ukuba zenzeke kwicandelo lokutya neli-beeko. Ifilimu ye-biellodegrady ye-biellophane ye-billophane yeplastiki kunye neengxowa zezona nqanaba liphezulu lokukhula elindelekileyo.
I-Cellophane kunye nephakeji yokutya ayizizo kuphela imizi-mveliso. I-seluplose ivunyiwe yi-FDA ukuba isetyenziswe:
Izinto zokutya
Iinyembezi ze-artificificificificificificial
I-filler yeziyobisi
Unyango lwenxeba
UCellophane ubonwa rhoqo ekufumaneni kokutya kunye neshishini lokugcina, amayeza, ukhathalelo lobuqu, ukhathalelo lwasekhaya, kunye namacandelo athengisayo.
Ngaba ziphangise iimveliso zeSeluploses kwishishini lam?
Ukuba ngoku sebenzisa iingxowa zeplastiki zeepipi, amantongomane, iimpahla ezibhakiweyo, njl. Njl. Yenziwe kwi-resin ebizwa ngokuba yindalo yendalo kwi-sellulose ethathwe kwi-Pulpu yeWoods, iingxowa zethu zomelele, icacile kwaye iqinisekisiwe.
Sinika izitayile ezimbini ze-biloegrades ze-bilophane kwiingxowa ezahlukeneyo:
Iingxowa zeFellophane
Iingxowa ze-celsene ze-cellophane
Sikwabonelela ngomthengisi wezandla, ukuze ukwazi ukukhangela ngokukhawuleza itywina iingxowa zakho zeCellophane.
Ngokuqala kokuqalisa, sizibophelele ekuboneleleni ngokubonelela ngeengxowa eziphezulu, ezinobuhlobo be-Ecophane kunye nephakeji engqokelela. Ukuba unomdla wokufunda ngakumbi malunga nokupakishwa kwefilimu yethu yeselselose okanye nayiphi na enye imveliso, nceda unxibelelane nathi namhlanje
I-PS iqinisekile ukuba uthenge iingxowa zakho ze-Cello kubathengisi abadumileyo njengephakeji elungileyo yokuqalisa. Imakethi emininzi yeshishini "Green" i-Cello ibikwe kwiplastiki yePolyproplene.
