Ikintu cyose Ukeneye Kumenya Gupakira Cellulose
Niba warigeze kureba mubikoresho byo gupakira ibidukikije byangiza ibidukikije, birashoboka ko wigeze wumva selile, izwi kandi nka selile.
Cellophane ni ibintu bisobanutse, byoroheje byabayeho kuva mu ntangiriro ya 1900. Ariko, birashobora kugutangaza kumenya ko selileophane, cyangwa sepile ya firime ya selile, ishingiye kubihingwa, ifumbire mvaruganda, nibicuruzwa "icyatsi" rwose.
Gupakira selile ni iki?
Yavumbuwe mu 1833, selile ni ikintu kiri imbere yinkuta za selile yibimera. Igizwe numurongo muremure wa molekile ya glucose, ikagira polysaccharide (ijambo ry'ubumenyi rya karubone).
Iyo iminyururu myinshi ya selile ihuza hydrogène hamwe, ikora mubintu bita microfibrile, bidahinduka kuburyo budasanzwe kandi bukomeye. Ubukomezi bwiyi microfibrile butuma selile ikora molekile nziza yo gukoresha mubikorwa bya bioplastique.
Byongeye kandi, selile ni biopolymer nyinshi cyane kwisi yose, kandi ibice byayo bifite ingaruka nke kubidukikije. Nubwo hariho uburyo butandukanye bwa selile. Gupakira ibiryo bya selile mubisanzwe ni selile, ibintu bisobanutse, binanutse, ibinyabuzima bishobora kwangirika.
Nigute ibicuruzwa bipfunyika bya selile byakozwe?
Cellophane ikorwa muri selile yakuwe mu ipamba, ibiti, ikivuguto, cyangwa andi masoko asarurwa ku buryo burambye. Itangira nkumuti wera ushonga, ni 92% –98% selile. Noneho, ifu ya selile mbisi inyura mu ntambwe enye zikurikira kugirango ihindurwe muri selile.
1. Cellulose ishonga muri alkali (umunyu wibanze, ionic yumunyu wa alkaline wibyuma) hanyuma ugasaza iminsi myinshi. Iyi nzira yo gushonga yitwa mercerisation.
2.
3. Iki gisubizo noneho kongerwaho kuvangwa na sodium sulfate na acide sulfurike. Ibi bihindura igisubizo muri selile.
4. Hanyuma, firime ya selulose inyura mubindi bitatu. Banza ukureho sulfure, hanyuma uhumure firime, hanyuma wongere glycerine kugirango irambe.
Igisubizo cyanyuma ni selofane, ikoreshwa mu nganda zipakira ibiryo, cyane cyane mu gukora imifuka ya selile yangiza cyangwa "imifuka ya selo".
Ni izihe nyungu zibicuruzwa bya selile?
Mugihe inzira yo gukora paki ya selile igoye, inyungu ziragaragara.
Abanyamerika bakoresha miliyari 100 z'amashashi buri mwaka, bisaba miliyari 12 z'amavuta buri mwaka. Hejuru y'ibyo, inyamaswa zo mu nyanja 100.000 zicwa hakoreshejwe imifuka ya pulasitike buri mwaka. Bifata imyaka irenga 20 kugirango ibikapu bya pulasitiki bishingiye kuri peteroli bigabanuke mu nyanja. Iyo babikoze, barema micro-plastike irushaho kwinjira murwego rwibiryo.
Mugihe societe yacu igenda irushaho kwita kubidukikije, dukomeje gushakisha ubundi buryo bwangiza ibidukikije, ibinyabuzima bishobora kwangirika kuri peteroli ishingiye kuri peteroli.
Usibye kuba ubundi buryo bwa plastiki, gupakira firime ya selile yerekana inyungu nyinshi kubidukikije:
Kuramba & bio-ishingiye
Kuberako selofane ikorwa muri selile yasaruwe mubihingwa, nigicuruzwa kirambye gikomoka kuri bio-ishingiye, umutungo ushobora kuvugururwa.
Biodegradable
Gupakira firime ya selile ni biodegradable. Ibizamini byagaragaje ko selile selile ipakira biodegrade muminsi 28-60 niba ibicuruzwa bidapfunditswe niminsi 80-120 iyo bisizwe. Yangirika kandi mumazi muminsi 10 niba idapfunditswe kandi ukwezi kumwe niba yatwikiriwe.
Ifumbire
Cellophane nayo ni nziza gushira mu kirundo cya fumbire murugo, kandi ntibisaba ikigo cyubucuruzi cyo gufumbira.
Ibyiza byo gupakira ibiryo:
Igiciro gito
Gupakira selile yabayeho kuva 1912, kandi ni umusaruro winganda zimpapuro. Ugereranije nibindi bikoresho byangiza ibidukikije byangiza ibidukikije, selofane ifite igiciro gito.
Kurwanya ubuhehere
Imifuka ya selile yibinyabuzima irwanya ubushuhe hamwe numwuka wamazi, bigatuma bahitamo neza kwerekana no kubika ibiryo.
Kurwanya amavuta
Mubisanzwe birwanya amavuta n'ibinure, bityo imifuka ya selofane ni nziza kubicuruzwa bitetse, imbuto, nibindi biribwa byamavuta.
Shyushya kashe
Cellophane ni ubushyuhe bwa kashe. Ukoresheje ibikoresho byiza, urashobora gushyushya vuba kandi byoroshye kashe kandi ukarinda ibiribwa bibitswe mumifuka ya selile.
Niki kizaza cyo gupakira selile?
Kazoza kafirime ya selilegupakira bisa neza. Raporo y'Isoko ry'ejo hazaza ivuga ko gupakira selile bizagira umuvuduko w’ubwiyongere buri mwaka wa 4.9% hagati ya 2018 na 2028.
70% by'iryo terambere biteganijwe ko bizabera mu rwego rw'ibiribwa n'ibinyobwa. Biodegradable selileophane ipakira firime hamwe namashashi nicyo cyiciro cyitezwe cyane.
Cellophane hamwe no gupakira ibiryo ntabwo aringanda zonyine selile ikoreshwa. Cellulose yemejwe na FDA kugirango ikoreshwe:
Ibiryo byongera ibiryo
Amosozi
Uzuza ibiyobyabwenge
Kuvura ibikomere
Cellophane igaragara cyane mu nganda y'ibiribwa n'ibinyobwa, imiti, ubuvuzi bwite, kwita ku ngo, no mu bucuruzi.
Ibicuruzwa bipakira selile birakwiriye kubucuruzi bwanjye?
Niba muri iki gihe ukoresha imifuka ya pulasitike kuri bombo, imbuto, ibicuruzwa bitetse, nibindi, imifuka yo gupakira selofane nubundi buryo bwiza. Ikozwe muri resin yitwa NatureFlex ™ ikozwe muri selile ikomoka ku mbaho, imifuka yacu irakomeye, irasobanutse neza kandi ifumbire ifumbire.
Dutanga uburyo bubiri bwa biodegradable selileophane imifuka mubunini butandukanye:
Amashashi ya selile
Gusseted selofane imifuka
Turatanga kandi kashe y'intoki, kugirango ubashe gushyushya vuba kashe ya selofane yawe.
Mugihe Cyiza cyo Gutangiza, twiyemeje gutanga ubuziranenge bwiza, bwangiza ibidukikije bya selofane imifuka hamwe nifumbire mvaruganda. Niba ushishikajwe no kumenya byinshi kubyerekeranye na firime ya selile ya selile cyangwa nibindi bicuruzwa byacu, nyamuneka twandikire uyu munsi
PS Wemeze ko ugura imifuka yawe ya selo kubatanga bazwi nka Good Start Packaging. Ubucuruzi bwinshi bugurisha imifuka ya "icyatsi" selo ikozwe muri plastiki ya polypropilene.
