Igikoresho citwa polyethylene terephthalate (PET) ni ubwoko bw’impuzu ikoreshwa cane mu gupfunyika ibifungurwa. Ivyo bituma izwi cane biva ku kuba igaragara neza cane, ikomeye be n’uko ishobora gukingira, ivyo bikaba bituma iba ikintu ciza cane co gupfunyika ibifungurwa bitandukanye. Ariko none PET vy’ukuri ni plastique y’ibifungurwa-? Iki kiganiro kizokwihweza cane ibiranga PET, ingene ikoreshwa mu gupfunyika ibifungurwa, no gusuzuma nimba ihuye n’ingingo ngenderwako z’amapulasitike y’ibifungurwa-. Ikindi, tuzokwihweza amasandugu atandukanye yo gupfunyika ibintu vy’i PET akoreshwa muri iyo nganda.
Gutahura ibikoresho vya PET
PET ni ivyuma bikorana n’ubushuhe, bikaba biri mu muryango w’ivyuma bita polyester. Ikoreshwa cane mu gukora intsinga z’impuzu, mu bikoresho vy’amazi n’ivy’ibifungurwa, no mu guhingura ibintu bikoreshwa n’ubushuhe. Igishushanyo caco c’imiti gifise ibice vy’ethylene terephthalate bisubiramwo, ivyo bikaba biha PET ubushobozi budasanzwe nk’ubukomezi bwinshi, ugushikama kw’ubushuhe n’ubushobozi bwiza cane bwo gukingira gazi. Ivyo bituma PET iba nziza cane mu gupfunyika, cane cane mu bijanye n’ibifungurwa, aho kubungabunga ibifungurwa bishasha no kwagura igihe co kubibika ari ngirakamaro cane.
Ibiranga PET
PET izwi kubera ko igaragara neza, igatuma abaguzi babona ico kintu biciye ku vyo gipfutse, ivyo bikaba ari ikintu ciza cane ku vyo kurya vyinshi. Irafise kandi inkomezi nyinshi-ku -uburemere, bikaba bituma ishobora gukomera kandi ikaba iremereye. Ikindi kandi, PET irafise ubushobozi bwo kurwanya imigera kandi ntikorana n’ibifungurwa, ivyo bikaba ari ngirakamaro kugira ngo ibifungurwa bibe vyiza. Kubera ko ifise ubushobozi bwiza cane bwo gukingira umwuka w’ikirere n’umwuka w’ikirere, bituma ibereye gupfunyika ibinyobwa birimwo gaze be n’ibindi biryo bishobora kwonona.
Umutekano n'amabwirizwa
Umutekano wa PET nk’ikintu co mu bwoko bw’ibifungurwa-gushigikirwa n’ibigo vyinshi bijejwe gucungera ibifungurwa kw’isi yose, harimwo n’Ishirahamwe ry’Ibifungurwa n’Imiti ryo muri Amerika (FDA) n’Ikigo c’Uburayi kijejwe umutekano w’ibifungurwa (EFSA). Ivyo bigo vyasuzumye PET maze bibona ko ataco bitwaye iyo ikoreshejwe mu bikorwa vyo gukorana n’ibifungurwa. Nk’akarorero, FDA yemeye ko PET yosubira gukoreshwa mu gupfunyika ibifungurwa, igihe gusa ihuye n’ingingo ngenderwako zidasanzwe z’ubusuku. Ukwo kwemerwa gushingiye ku bushakashatsi bwinshi bwa siyansi n’igerageza ryerekanye ko PET idahinduka be n’uko idashobora gukorana n’ibirungo vy’ibifungurwa.
Ikoreshwa rya PET mu gupfunyika ibifungurwa
PET ikoreshwa cane mu bikorwa bitandukanye vyo gupfunyika ibifungurwa kubera ko ishobora gukoreshwa mu buryo bwinshi kandi ikora neza cane. Ikoreshwa cane mu gukora amacupa y’ibinyobwa, ibibindi vy’ibirungo, n’ibibindi vy’ibifungurwa biteguye-kurya. Ikindi, PET ikoreshwa kandi mu guhingura amasandugu yo gupfunyika ibifungurwa-grade PET kugira ngo ishobore gushitsa ivyo ibice bitandukanye vy’ubuhinga bw’ibifungurwa bikeneye.
Amasandugu yo gutekamwo imikate y’ibikoko (PET) yagenewe canecane gupfunyika ibintu vy’imikate. Uguseruka kwayo gutuma abaguzi babona neza ico kintu, mu gihe inkomezi zaco zituma igipfukisho gishobora kwihanganira gufatwa mu gihe co gutwara no kugaragaza. Amasandugu yo gutekamwo imikate y’i PET na yo nyene arafise ubushobozi bwo gukingira ubukonje-n’amavuta-, ivyo bikaba bifasha kugumana ubushasha n’uburyo bw’ibifungurwa vy’imikate.
Amasandugu y’ibifungurwa vy’ibikoko (PET) akoreshwa mu gupfunyika ibifungurwa bitandukanye, kuva ku nkoko n’ivyamwa vyumye gushika ku bifungurwa vy’ibirayi n’ibisuguti. Izo sandugu zizibira neza ubukonje n’umwuka w’ikirere, ivyo bikaba ari ngirakamaro kugira ngo ntivyononekare no kugira ngo ibifungurwa vyo mu gitondo bigume bimeze neza kandi bifise akamoto keza. Ivyo PET ifise bifise uburemere buke kandi bituma iba ihitamwo ryiza ryo gupfunyika ibifungurwa vy’ingurube bishobora gutwara.
Amasandugu yo gupfunyikiramwo imboga za PET atanga inyungu nyinshi ku bihingwa bishasha. Uguseruka kwa PET bituma abaguzi bashobora gusuzuma ko imboga zishasha batafunguye ivyo zipfutse. Vyongeye, PET irashobora kubumbwa mu mibumbe n’ubunini butandukanye, ivyo bikaba bituma ishobora gupfunyika ubwoko butandukanye bw’imboga, kuva ku mboga zifise amababi gushika ku mboga zifise imizi.
Ivyo gupfunyika inyama bikwiye gukorwa mu bikoresho bishobora kwihanganira ubushuhe buke kandi bikazibira neza ibintu bihumanya. Amasandugu yo gupfunyikiramwo inyama z’ibikoko (PET) akozwe kugira ngo ahure n’ivyo bisabwa, bikaba bitanga uburinzi bwiza cane ku nyama zishasha be n’izitunganijwe. Inkomezi z’ico kintu be n’ukuntu gica ibibatsi bituma ico kintu kirindwa neza kandi kigakwegera abaguzi.
Ivyerekeye ibidukikije
Uretse ivyiza bifise mu bikorwa, PET irakundwa kandi kubera ko igira akamaro ku bidukikije. Ni 100% ishobora gusubirwamwo, kandi uburyo bwo gusubirwamwo burashobora kugabanya cane ikirenge ca carbone gifitaniye isano n’ivyo ikora-. PET yasubiwemwo (rPET) iriko irakoreshwa cane mu bijanye no gupfunyika ibifungurwa, bikaba bitanga ubundi buryo buramba bwo gusubirira PET y’isugi. Gukoresha rPET ntibizigama gusa ubutunzi, ariko kandi biragabanya n’imyanda y’amapulasitike ihera mu bibanza vy’imyanda.
Gusubira gukoresha ibintu n'ugukomeza
Gusubira gukoresha PET ni uburyo bushingiye neza -bushiramwo gukoranya, gutoranya, gusukura, no gusubira gukoresha kugira ngo amaherezo haboneke ibintu bishasha. Ubu buryo bw’uruzitiro rwugarijwe-bufasha kugabanya ingaruka mbi ku bidukikije no gushigikira ubutunzi buzunguruka. Amashirahamwe menshi ubu ariko arongerako ibikoresho vyasubiwemwo mu bikoresho vyayo vy’ubuhinga bwa PET, ivyo bikaba bituma gusa abona ko ari ibintu bishobora kugumaho, ariko kandi bikaba bituma abaguzi bashobora gukoresha ibintu bitagira ingaruka ku bidukikije.
Iciyumviro
Mu gusozera, PET ni vy’ukuri igikoresho co gupfunyika ibifungurwa-gifise ivyiza vyinshi mu gupfunyika ibifungurwa. Umutekano wayo, ubushobozi bwo gukoreshwa mu buryo bwinshi be n’ivyiza biva ku bidukikije bituma abahinguzi n’abaguzi bayihitamwo cane. Ubwoko butandukanye bw’amasandugu yo gupfunyikiramwo ibintu, nk’amasandugu y’ibifungurwa vy’i PET n’amasandugu y’inyama z’i PET, birahuye n’ivyo inganda zikora ibifungurwa zikeneye bitandukanye, bikaba bituma ibintu biguma ari bishasha, bifise umutekano kandi bikwegera abaguzi. Uko iyo nganda ikomeza gutera imbere, PET itegerezwa kugira uruhara runini kuruta mu gutorera umuti ibibazo vy’ugupfunyika ibifungurwa, gutyo ikarushiriza gukomeza ikibanza cayo nk’ikintu nyamukuru mu bijanye no gupfunyika ibifungurwa.
