Umutekano
Ivyokurya-grade PET ikoreshwa cane mu gupfunyika ivyokurya n’ibinyobwa kandi yemewe cane kubera umutekano wayo n’ugushikama kwayo. Ntiyirekura ibintu bishobora gutera ingorane kandi ihuye n’ingingo mfatirwako mpuzamakungu zijanye n’umutekano w’ibifungurwa, ivyo bikaba bituma abaguzi baruhuka igihe bariko barayikoresha. Ariko rero, hari ikintu kimwe gikeneye kwitwararikwa cane: PET irashobora kurekura ibintu bimwebimwe bishobora gutera ingorane, nka DEHP+, iyo hari ubushuhe bwinshi. Ku bw’ivyo, igihe ukoresha ibikoresho vya PET, urabe ko wirinda ubushuhe bwinshi kugira ngo ntusohoke ibintu bishobora gutera ingorane.
Ivyokurya-grade PP biri hose mu buzima bwacu bwa misi yose, nk’amasandugu yo kubika ibifungurwa bishasha-mu maduka manini n’amasandugu y’ifunguro ry’umutaga ryo mu micro-onde, menshi muri yo akozwe muri PP. Ni kuki rizwi cane? Mbere na mbere, iki kintu nta -ubumara gifise, nta n’akamoto kigira kandi nta n’akamoto kigira, ivyo bikaba bituma gikoreshwa neza cane. Ikindi kandi, irafise ubushobozi bwiza cane bwo guhangana n’ubushuhe kandi ishobora gushirwa muri micro-onde kugira ngo ishushe ivyokurya ata ngorane. Ntizosenyuka iyo ishushe nk’amapulasitike amwamwe kandi irashobora no kurekura ibintu bishobora gutera ingorane. Muri iki gihe, ukudahungabana kwayo mu vy’imiti na kwo nyene ni kwiza cane. Mu gihe umuntu akoresha mu buryo busanzwe, ntivyoroshe gukorana n’ibindi bintu.
Ikiruta vyose, ibikoresho vya PP ntibisaba ko hongerwako ikintu na kimwe co gutera ingorane mu gihe c’uguhingura. Mu bihe vy’ubushuhe bwinshi, ntizobora bisphenol A*, umuti ushobora gutera ingorane umubiri w’umuntu. Ivyo bisigura ko ibikoresho vyo ku meza canke ibikoresho vyo gupfunyika bikozwe mu bikoresho vya PP ari vyo bitekanye kandi cane cane bibereye kubika ibifungurwa. Ku bw’ivyo, igihe umuntu ahitamwo ibikoresho vyo gupfunyika ibifungurwa canke ibikoresho vyo ku meza, ibikoresho vya PP birashobora gushirwa imbere. Nakare, umutekano ni wo uza imbere.
Guseruka
Ivyokurya-grade PET birafise ubusobanuro bwinshi cane, bigufasha kubona ivyokurya biri imbere mu kanya nk’ako gukubita urugohe, kandi ukuntu bisa n’uko bimeze biragaragara neza. Ni co gituma ari vyiza canecane gukoreshwa mu gupfunyika ibifungurwa bikeneye kwerekana ivyo kurya, nk’amacupa y’ibinyobwa dukunda kunywa, be n’ibibindi vy’ibifungurwa vy’ibisuguti n’ibiseke. Vyinshi muri ivyo bipapuro bikozwe mu bikoresho vy’ubuhinga bwa PET. Kubera iki woyikoresha? Ni kubera ko abacuruzi bashaka kwereka abaguzi uruhande rwiza rw’ibintu vyabo no kubakwegera ngo bagure. Ikindi kandi, ubwo bwoko bw’ibipfukisho ntibuboneka gusa ko ari bushasha kandi busukuye, ariko kandi burakingira ivyokurya ku rugero runaka, bikabibuza gutonyanga no gusenyuka, bigatuma ivyokurya bishika mu minwe y’abaguzi bitagiramwo ikintu kandi biri mu mimerere myiza.
Ivyokurya-grade PP bifise urugero ruto rw'uguca ibibatsi, mu bisanzwe bikaba bica ibibatsi. Naho umuco udashobora guca neza, irakoreshwa mu buryo bwinshi. Fata nk’akarorero akazu k’amavuta y’ibitoke. Ivyo bikoresho vy’i PP bica ibibatsi bituma abantu babona neza ukuntu iyo yogurt iteye, mu gihe kandi bisiga inyiyumvo y’akabanga ku kintu. Hariho kandi n’ibitereko bikunze kuboneka mu maduka maninimanini. Inyama nshasha ni akarorero gasanzwe. Amapaleti akozwe mu bikoresho vya PP ntashobora gusenyuka- kandi arakora, kandi uburyo bwayo buca ibibatsi buraboneka ko busukuye kandi bufise isuku. Gukoresha ibikoresho vya PP mu gukora amasandugu n’ibitereko vy’ibifungurwa ntibishobora gusa gushitsa ivyo bikenewe ariko kandi biratuma ibifungurwa biguma bitekanye.
Uguhangana n'ubushuhe
Uguhangana n'ubushuhe ni ikintu nyamukuru kiranga ibiribwa-grade PET. Naho ishobora guhangana n’ubushuhe-, ntishobora guhangana n’ubushuhe bwinshi. Iyo ubushuhe bushitse kuri 70-80 degrees , uruhande rw’ivyo bipapuro vya PET ruzohinduka kandi rutakaze uburyo rwari rufise mbere. Ku bw’ivyo, ibiribwa-grade PET ntibikwiye gukoreshwa mu bihe aho bikenewe ko umuntu akoresha ubushuhe bwinshi-gutera ubumara canke gushusha.
