Ibyiza by'imyenda idafunze uzi ni ingano yayo | JINHAOCHENG

Igicuruzwa cyakozwe muriumwenda utari uwo kubohaNi ibikoresho bishya byo mu bwoko bwa "vitektorial" bitagira ingaruka ku bidukikije. Birinda ubushuhe, bihumeka, byoroshye, byoroheje, ntibishya, byoroshye kubora, ntibihumanya kandi ntibitera umujinya, bifite ibara ryiza, igiciro gito kandi bishobora kongera gukoreshwa.

Ibikoresho bishobora kubora mu buryo busanzwe nyuma yo gushyirwa hanze mu gihe cy'iminsi 90. Bishobora kumara imyaka 5. Ntabwo ari uburozi, nta mpumuro kandi nta bintu bisigaye bifite iyo bitwitswe, bityo ntibihumanya ibidukikije kandi bizwi ku rwego mpuzamahanga nk'ikintu kitangiza ibidukikije kirengera ibidukikije by'isi.

Ibyiza:

1. Uburemere bworoheje: Polypropylene resin ni yo mashini nyamukuru ikoreshwa mu gukora. Uburemere bwihariye ni 0.9 gusa, ni kimwe cya gatatu cya bitanu by'ipamba, iryoshye kandi rimeze neza.

2. Ntirigira uburozi, ntirigira umujinya: Iki gicuruzwa cyakozwe hakurikijwe ibikomoka ku biryo bya FDA, nta bindi bigize imiti, gifite imikorere ihamye, ntirigira uburozi, nta mpumuro igira, kandi ntigira uruhu rubi.

3. Imiti irwanya bagiteri n'imiti: Polypropylene ni ikintu kidakora neza mu mikorere ya shimi, kidatera imiyoboro, kandi gishobora gutandukanya bagiteri n'udukoko mu mazi. Imiti irwanya bagiteri, ingese ya alkali, n'ibicuruzwa byarangiye ntibigira ingaruka ku mbaraga ziterwa no gutwarwa n'isuri.

4. Imiterere myiza y’umubiri: Ikorwa hakoreshejwe polypropylene izunguruka mu buryo butaziguye mu muyoboro, kandi imbaraga z’umusaruro ni nziza kurusha iz’ibicuruzwa bisanzwe bya fibre, imbaraga ntizigana mu cyerekezo, kandi imbaraga z’uburebure n’iz’ubugari zirasa.

5. Mu bijyanye no kurengera ibidukikije, ibikoresho fatizo bikoreshwa mu myenda myinshi idafunze ni polypropylene, naho ibikoresho fatizo bikoreshwa mu mifuka ya pulasitiki ni polyethylene. Nubwo ibyo bintu byombi bifite amazina asa, bifite imiterere itandukanye cyane ya shimi. Imiterere ya molekile ya shimi ya polyethylene ifite ubuziranenge bugaragara kandi biragoye cyane kuyihindura. Kubwibyo, bifata imyaka 300 kugira ngo ishashi ya pulasitiki ibore. Imiterere ya shimi ya polypropylene ntabwo ikomeye, kandi uruhererekane rwa molekile rushobora gucika byoroshye, kugira ngo rushobore kwangirika neza. Kandi mu buryo butari uburozi mu gihe gikurikiraho,isakoshi yo guhaha idafunzeishobora kubora burundu mu minsi 90. Byongeye kandi, isakoshi idafite ubudodo ishobora kongera gukoreshwa inshuro zirenga 10, kandi igipimo cy'ihumana ry'ibidukikije nyuma yo gutabwa ni 10% gusa by'isakoshi ya pulasitiki.
