Ibintu byose ukeneye kumenya kubyerekeye gupakira selile
Niba waragiye mu bikoresho bipakira ibidukikije, amahirwe numvise selile, uzwi kandi nka Cellephane.
Cellophane ni ibintu bisobanutse, byuganwa byabayeho kuva mu ntangiriro ya 1900. Ariko, birashobora kugutangaza ngo umenye ko clophane, cyangwa filime ya filime, ari igihingwa gishingiye ku gihingwa, covastable, kandi "icyatsi".
Gupakira selile ni iki?
Yavumbuwe mu 1833, selile ni ibintu biherereye imbere kurukuta rw'Akagari wibiti. Igizwe numunyururu muremure wa molekile za glucose, zituma ihindura polysacharide (ijambo rya siyansi kuri carbohydte).
Iyo iminyururu myinshi ya exrogène ifitanye isano hamwe, zikora mubintu bita microfibrils, bikunze guhiga kandi bikomeye. Gukomera kwa microfibrils bituma selile molekile nziza cyane ikoreshwa mumusaruro wibinyabuzima.
Byongeye kandi, selile niwo biolymer nziza cyane ku isi yose, kandi ibice byayo bifite ingaruka nke z'ibidukikije. Nubwo hari uburyo butandukanye bwa selile. Gupakira ibiryo bya Cellus ni ubusebe, busobanutse, bunanutse, biodegradade-biodegrada-nkibikoresho.
Nigute ibicuruzwa bya filime byapakiwe?
Cellophane yaremwe kuva kuri selile yakuwe mu ipamba, ibiti, inkwi, cyangwa ibindi bisarurwa burundu. Bitangira nkinkoko yera ishonga, ifite 92% -98%. Noneho, ihuriro rya selile mbisi rinyuze mumirongo ine ikurikira kugirango rihindurwe muri celiphane.
1.. Ubugari bwa Centul bashonga muri Alkali (umunyu wibanze, uoonic wicyuma cya alkaline cyuma) hanyuma bikabazwa iminsi myinshi. Iyi nzira isebanya yitwa amakosa.
2. Gutandukanya karuboni bikoreshwa kuri pulp ya mercerinzwe kugirango hatere igisubizo cyitwa selile xanthate, cyangwa vizabu.
3. Iki gisubizo cyongeyeho kuvanga sodium sulfate na aside sulfuric sulfurike. Ibi bihindura igisubizo muri selile.
4. Ubwa mbere kugirango ukureho sulfure, hanyuma ukongere firime, hanyuma wongere glycerin kugirango iramba.
Ibisubizo byanyuma ni Cellophane, bikoreshwa mubikorwa byo gupakira ibiryo, cyane cyane gukora imifuka ya Cellophine cyangwa "Cello".
Ni izihe nyungu z'ibicuruzwa bya selile?
Mugihe inzira yo gukora ibipfunyika bya selire biragoye, inyungu zirasobanutse.
Abanyamerika bakoresha imifuka miliyari 100 za pulasitike buri mwaka, bisaba ibibari 12 bya peteroli buri mwaka. Hejuru y'ibyo, inyamaswa zo mu mazi 100.000 ziciwe binyuze mu mifuka ya pulasitike buri mwaka. Bisaba imyaka irenga 20 imifuka ya plastike ishingiye kuri peteroli kugirango iteshegure mu nyanja. Iyo babikoze, barema micro-plastike kurushaho kwinjira murunigi rwibiryo.
Nkuko societe yacu ikura ibinyuranye mubidukikije, dukomeje gushakisha ubundi buryo bwinshuti, biliodedapable kuri plastiki ishingiye kuri peteroli.
Usibye kuba ubundi buryo bwa plastiki, filime ya filime ihabwa inyungu nyinshi zishingiye ku bidukikije:
Birambye & Bio-Bishingiye
Kuberako Celilophane yaremwe kuva muri selile yasaruwe mubimera, nibicuruzwa birambye bikomoka kubikoresho bishingiye kuri bio, bivuguruzanya.
Biodegradable
Pasiporo ya filime ni biodegraduble. Ibizamini byerekanye ko biodegrade ya selile mu minsi 28-60 niba ibicuruzwa byashyizwe ku munsi na 80-120 iyo bifunze. Iratesha agaciro kandi mumazi muminsi 10 niba yanduye kandi hafi ukwezi iyo igeze.
Affikore
Clorphane nayo ifite umutekano gushyira mu ifumbire yawe mu rugo, kandi ntibisaba ikigo cy'ubucuruzi cy'ifumbire.
Inyungu zipakira ibiryo:
Igiciro gito
Pajinya ya Cellulose yabaye hafi kuva mu 1912, kandi ni ibihano by'inganda z'impapuro. Ugereranije nubundi buryo bwa plastike bwa plastike, clophane ifite ikiguzi gito.
Ubuhehere
Imifuka ya Cellophine yo muri Biodefe zirwanya ubushuhe numwuka wamazi, bikababera amahitamo meza yo kwerekana no kubika ibiryo.
Amavuta arwanya peteroli
Mubisanzwe barwanya amavuta n'amavuta, bityo imifuka ya Callophane irakomeye kubicuruzwa bitetse, imbuto, nibindi biribwa byamavuta.
Ubushyuhe
Cellophane ni kashe. Hamwe nibikoresho byiza, urashobora guhita kandi byoroshye gukomera no kurengera ibicuruzwa bibitswe mu mifuka ya Cellophane.
Igihe kizaza cyo gupakira kwa selile ni he?
AhazazaFilimegupakira bisa neza. Raporo yubushishozi bwamasoko yamasoko ihanura ibipfunyika bya selire bizaba bifite umubare wiyongera buri mwaka wa 4.9% hagati ya 2018 na 2028.
Biteganijwe ko mirongo irindwi ku ijana by'iryo terambere rizaba mu biribwa n'ibinyobwa. Biodegradable Gupakira Film hamwe nimifuka ni icyiciro cyo gukura cyane.
Cellophane hamwe no gupakira ibiryo ntabwo arizo nganda zonyine zikoreshwa. Cellulose yemejwe na FDA yo gukoresha:
Ibiryo
Amarira ahinnye
Kuzuza ibiyobyabwenge
Guvura ibikomere
Cellophane igaragara akenshi mu nganda zibiribwa n'ibiribwa, imiti, kwita ku muntu ku giti cye, kurera urugo, no gucuruza urugo.
Ibicuruzwa bipakira selile birakwiriye ubucuruzi bwanjye?
Niba ubu ukoresha imifuka ya pulasitike kuri bombo, imbuto, ibicuruzwa bitetse, nibindi, imifuka yo gupakira impimbano ni ubundi buryo bwiza. Bikozwe mu rubanza rwitwa gutukana ™ ikozwe muri selile yakomotse mu giti, imifuka yacu irakomeye, ya kirimbuzi kandi yemewe.
Dutanga uburyo bubiri bwimifuka ya clophafe zihuza muburyo butandukanye:
Imifuka ya clophane
Imifuka ya callefane
Turatanga kandi umupira wamaboko, kugirango ubashe gufunga byihuse imifuka ya Cellephane.
Mugihe cyiza cyo gupakira, twiyemeje gutanga imifuka myiza yinshyi zuzuye, ibidukikije byangiza ibidukikije nibipfunyika. Niba ushishikajwe no kwiga byinshi kubyerekeye pasiporo yacu ya filime cyangwa ikindi kintu cyose, nyamuneka twandikire uyu munsi
Zab menya neza ko ugura imifuka ya Cello mubitanga bizwi nkibipakira. Isoko ryimikoreshereze myinshi "icyatsi" cello bikozwe muri plastiki ya polypropylene.
