Mu kibano ca none, gukoresha ibikoresho vy’amapulasitike mu kubika ibifungurwa birakwiragiye cane. "Ivyo kurya-grade" vyerekeye ibikoresho bishobora gukorana n'ivyo kurya, kandi gutahura amapulasitike ahuye n'ico kigereranyo ni ikintu gihambaye cane ku bahinga no ku baguzi. Mu mapulasitike atandukanye, PET (polyéthylène terephthalate) irazwi cane kubera ko ataco ihungabanya kandi ikoreshwa cane mu gupfunyika ibifungurwa. Iki kiganiro kizoca irya n’ino ibiranga amapulasitike y’ibifungurwa-, yibanda ku masandugu yo gupfunyika ibifungurwa y’agaciro ka PET, no gusigura igituma abonwa ko ari uburyo bwo kubika ibifungurwa butekanye kandi bwizewe.
Menya ivyerekeye ibifungurwa-amapulasitike y'agaciro
Amapulasitike y’urugero rw’ibifungurwa-ni ibikoresho vyageragejwe n’ibigo bijejwe gucungera ibifungurwa n’imiti nk’Ishirahamwe ry’Ibifungurwa n’Imiti ryo muri Amerika (FDA) n’Ikigo c’Uburayi kijejwe umutekano w’ibifungurwa (EFSA) kandi vyabonwa ko ataco bihungabanya iyo umuntu akoresheje ibifungurwa. Izo pulasitike ntizitegerezwa kuba zirimwo imiti ishobora gutera ingorane mu vyo kurya maze igatera ingorane amagara. Ivyiyumviro vyerekeye amapulasitike yo mu rwego rw’ibifungurwa-birimwo ukudashobora gutera ubumara, ukudashobora gusenyuka n’imiti, n’ubushobozi bwo kuguma ahagaze neza kandi kudasenyuka mu bushuhe butandukanye.
Mu mapulasitike atandukanye, PET ni kimwe mu bikoresho bikoreshwa cane mu gupfunyika ibifungurwa. Ivyo bituma izwi cane kubera ko ifise ubushobozi bwiza cane bwo gukingira, ivyo bikaba bifasha ibiribwa kuguma bishasha kandi bimeze neza. PET kandi irafise ivyiza nk’uko idakomeye cane, idashobora gusenyuka-, kandi ishobora gusubirwamwo, ivyo bikaba bituma iba uburyo bwo gukingira ibidukikije. Amasandugu y’ibipapuro vy’ibikoko (PET) arakundwa canecane kubera ko abona neza, ivyo bikaba bituma abaguzi bashobora kubona ibirimwo bitagoranye.
Ibirango vya PET nk'ibikoresho vy'ibiribwa-
PET ni igikoresho citwa polyester gikozwe mu bihimba vy’umubiri biva mu bihimba vy’umubiri bita éthylène glycol n’ivyuma bita aside terephtalique. Ivyo bihimba vy’umubiri bikora bituma igira uburemere bwinshi bw’amabuye y’agaciro, ivyo bikaba bituma igira inkomezi nyinshi kandi ikagumaho. Kimwe mu bintu nyamukuru biranga PET ni ukuntu idakora, ivyo bikaba bisobanura ko itazokorana n’ibirungo vy’ibifungurwa. Ico kiranga ni ikintu gihambaye cane mu kubungabunga ubutungane n’umutekano w’ibifungurwa.
Vyongeye, PET irashobora guhangana n’aside n’amavuta, ivyo bikaba bikunze kuboneka mu vyo kurya. Ukwo guhangana n’ugusenyuka kw’ibifungurwa bituma ivyo bipfukisho bitazokwonona canke ngo bigire ico bikoze ku buzima bw’ibifungurwa. Vyongeye, PET irashobora kwihanganira ubushuhe butandukanye, kuva ku gukonja gushika ku guteka, ata gutakaza ubutungane bwayo. Ivyo bituma ishobora gukoreshwa mu buryo bwinshi bwo kubika ibifungurwa, kuva ku bifungurwa biri mu frigo gushika ku binyobwa bishushe.
Ikoreshwa ry'ibifungurwa-amasandugu ya PET
Amasandugu ya PET yo mu rwego rw’ibifungurwa-akoreshwa cane, kuva ku kubika ibifungurwa vyo mu rugo gushika ku gupfunyika ibifungurwa vy’ubudandaji. Mu rugo, ayo masandugu ni meza cane yo kubikamwo amasigarira, gutegura ivyo kurya no gutunganya ivyo kubika mu nzu y’ibifungurwa. Kubera ko ibonerana kandi idakomeye cane, bituma yoroha kuyikoresha mu buzima bwa misi yose.
Mu rwego rw’ubudandaji, amasandugu ya PET arakoreshwa cane mu gupfunyika ibifungurwa bishasha, ibifungurwa vy’imikate, n’ibifungurwa biteguwe-kuribwa. Ivyokurya-amasandugu ya PET arakundwa cane cane mu bijanye n’ibifungurwa bishasha kuko abuza neza ubukonje n’umwuka, gutyo bikaba bituma ivyamwa n’imboga bimara igihe kirekire. Ivyo ntibifasha gusa ivyimburwa kuguma bishasha, ariko kandi biragabanya n’ugusesagura ivyokurya.
Ingaruka ku bidukikije no gusubira gukoresha PET
Kimwe mu vyiza bihambaye vy’i PET ni uko ishobora gusubirwamwo. PET irashobora gusubirwamwo incuro nyinshi ataco itakaje, ivyo bikaba bituma iba uburyo buramba bwo gupfunyika ibifungurwa. Ivyo gusubira gukoresha ibintu bishasha birimwo gusukura no gusubira gufukura kugira ngo haboneke ibintu bishasha, gutyo bikagabanya ivyifuzo vy’amapulasitike y’isugi kandi bikagabanya ingaruka mbi ku bidukikije.
Gusubira gukoresha PET ntibizigama gusa ubutunzi, ariko kandi biragabanya imyuka itera ibidukikije ijana n’uguhingura amapulasitike. Amashirahamwe menshi ubu arakoresha uburyo bwo gusubira gukoresha ibintu bishasha (closed-loop) kugira ngo akoranirize hamwe ibikoresho vya PET, abisubire gukoresha, yongere abikoreshe mu guhingura ibintu bishasha. Ubwo buryo burahuye n’ingingo ngenderwako z’ubutunzi buzunguruka, bugatuma haba iterambere riramvye no kugabanya imyanda.
Ingorane n'ivyo kwiyumvira mu gukoresha PET mu gupfunyika ibifungurwa
Naho PET ifise ivyiza vyinshi, gukoresha iyo nzira mu gupfunyika ibifungurwa na vyo nyene birafise ingorane zimwezimwe. Kimwe mu bibazo nyamukuru ni uko imiti yoshobora gusohoka, cane cane iyo PET iri mu bushuhe bwinshi. Naho muri rusangi PET ibonwa ko ataco ihungabanya, amabwirizwa yerekeye ubushuhe ategerezwa gukurikizwa ata guca ku ruhande kugira ngo ntihagire ingorane iyo ari yo yose yo kwanduza.
Ikindi kintu co kwitwararika ni ingaruka mbi ziterwa n’uguhingura PET ku bidukikije. Naho PET ishobora gusubirwamwo, uburyo bwo kuyikora burakoresha inguvu nyinshi-kandi bwishingikiriza ku bintu bitashobora gusubirwamwo. Kugira ngo izo ngaruka zigabanuke, abahinguzi bariko bararondera uko bokoresha ibikoresho vya PET (rPET) vyasubiwemwo n’ibikoresho vya PET bishingiye ku binyabuzima-, ibikoresho biva mu bikoresho bishobora gusubirwamwo bifise ikirenge gitoyi c’umuyagankuba.
Iciyumviro
Mu ncamake, PET ni ikintu co gupfunyika ibiribwa gishobora gukoreshwa mu buryo bwinshi kandi co kwizigirwa. Kubera ko itekanye, iramba kandi ishobora gusubirwamwo, bituma iba nziza cane ku baguzi no ku bayihingura. Kubera ko hariho ugushaka gukomeye kw’imiti yo gupfunyika ibintu mu buryo buramba, ugutegura ibintu bishasha vy’ibifungurwa, nk’amasandugu y’ibifungurwa-, bizogira uruhara runini mu gushitsa ivyo inganda zikora ibifungurwa zikeneye no kugabanya ingaruka mbi ku bidukikije. Mu gutahura imiterere n’imikorere y’ibifungurwa-vy’amapulasitike, turashobora gufata ingingo zishingiye ku makuru zihuza umutekano n’ubuzima buramba.
