Ese impapuro za PE Laminated Paper zifite uburozi? Isesengura ryimbitse ry’amahame yemewe n’ibimenyetso bya siyansi
Impapuro za PE zometseho, ikoreshwa cyane mu gupfunyika ibiribwa no mu bikoresho bikoreshwa buri munsi, yakunze gukurura abantu benshi ku bijyanye n’umutekano wayo, ikibazo nyamukuru kikaba kirimo “Ese Impapuro za PE Laminated “uburozi?”. Hashingiwe ku bipimo mpuzamahanga n’ibyemewe mu gihugu ndetse n’amakuru y’ibizamini by’umwuga, igisubizo kirasobanutse: impapuro za PE zikozwe muri laminated zihuye n’ibipimo byemewe nta ngaruka mbi ku mubiri w’umuntu mu gihe gisanzwe gikoreshwa; ingaruka mbi ku mutekano zishobora kubaho gusa iyo ibicuruzwa bitujuje ibisabwa cyangwa bikoreshejwe mu bihe bidasanzwe.
Imiterere y’ingenzi y’impapuro za PE laminated ni ugusiga urwego rwa polyethylene (PE) ku rupapuro rw’ibanze binyuze mu nzira yo gushonga ishyushye. Polyethylene ubwayo ni ibikoresho bidafite isuku bifite imiterere ihamye ya shimi, byamaze kwemerwa n’inzego nyinshi z’ubutegetsi mpuzamahanga nk’ibikoresho byizewe byo gukora ku biribwa. Ibipimo ngenderwaho by’igihugu cy’Ubushinwa bya GB/T 36392-2018 “Impapuro za Laminated n’Inama y’Ubuyobozi yo Gupakira Ibiryo” bivuga neza ko kwimuka kose kwa PE laminated impapuro zo kuryaGuhuza ibyuma bigomba kuba ≤10 mg/dm², ingano y’icyuma gikomeye (Pb) igomba kuba ≤3 mg/kg, cadmium (Cd) ≤0.2 mg/kg, kandi nta bintu byangiza nk’ibicanwa by’amashanyarazi bigomba kugaragara. Ikigo gishinzwe kurwanya indwara zandura muri Amerika (FDA) gishyiraho amategeko akomeye agenga ibikoresho bya PE byo gusiga ku biryo binyuze kuri 21 CFR 177.1520, gisaba ko ibikomoka ku bimera byimuka bikora neza.
Hari ibintu bibiri by’ingenzi bigira ingaruka ku mutekano w’impapuro za PE. Icya mbere, kubahiriza ibicuruzwa: Impapuro za PE zakozwe n’inganda zitemewe zishobora gukoresha imyanda yasubiwemo, ibikoresho fatizo bya PE bike, cyangwa kongeramo pulasitiki zibujijwe nka phthalate, bishobora guteza ibyago byo kwimuka kw’ibintu byangiza. Icya kabiri, ikoreshwa: Aho PE ishongesha ni hafi 120-130℃. Iyo ubushyuhe bwa serivisi burenze 110℃ (nk’ubushyuhe butaziguye mu ifuru ya mikoroonde cyangwa gukora ku muriro ufunguye), cyangwa iyo ihuye n’ibiryo bifite amavuta menshi igihe kirekire, bishobora kwihutisha kwimuka kw’ibintu byangiza. Amakuru y’ubushakashatsi agaragaza ko kwiyongera kw’imbaraga za mikoroonde n’ubushyuhe byongera cyane igipimo cy’ukwimuka kw’impapuro za PE za mikoroonde, aho ingufu za mikoroonde zigira ingaruka zigaragara cyane, zishobora kongera igipimo cy’ukwimuka ku kigero cya 20%.
Kugira ngo abaguzi n’abaguzi bakoreshwe mu buryo butekanye, bagomba kwita ku ngingo eshatu: Ubwa mbere, hitamo ibicuruzwa bifite icyemezo cy’uko bikurikiza amategeko, nk’impapuro za PE zatsindiye icyemezo cya FDA kandi zujuje ibisabwa bya GB 4806, kandi urebe raporo z’ibizamini n’ibyemezo by’uko bikurikije amategeko byatanzwe n’uruganda. Icya kabiri, kurikiza amabwiriza y’ikoreshwa: irinde gushyushya ibiryo bipfunyitse mu mpapuro za PE zashyizwe mu ifuru ya mikoroonde, kandi ntukabikoreshe mu kubika ibiryo bishyushye cyane birengeje 100°C. Hanyuma, shyira imbere ibicuruzwa bifite Virgin Wood Pulp ibikoresho by’ibanze n’uburyo bwo gusiga amazi, ibyo bikaba bidafite umutekano mwiza gusa ahubwo binagabanya imyuka ihumanya ikirere kandi bikaba bitangiza ibidukikije.
Nk’umuntu w’umwuga utanga ibisubizo ku bicuruzwa by’impapuro, Paperjoy’sIbikoresho by’impapuro bya PE byashyizwemo laminated PE bikoresha ibikoresho fatizo bya PE byo mu rwego rwo hejuru hamwe n’ibikoresho by’ibanze by’ibiti byemejwe na FSC, bikurikiza inzira zo gukora neza, bigatsinda ibyemezo byinshi byemewe nka FDA na ISO9001, kandi buri cyiciro cy’ibicuruzwa gifite raporo zuzuye z’ibizamini kugira ngo harebwe ko bishyirwa mu bikorwa neza mu bipfunyika by’ibiribwa, mu bicuruzwa bikoreshwa mu guteka n’ibindi.
