Udupira duto twa Sio2 tw’Ubwiza Bwiza twa 2021 - Udupira duto tw’ibirahure byoroshye byo kuzuza irangi – Kehui

Uduce duto tw’ibirahure dufite ubucucike buke, uburemere bworoshye n’imbaraga nyinshi. Bitewe n’imiterere y’ubucucike, ugereranije n’udusaro dusanzwe tw’ibirahure, dufite imiterere y’ubucucike bworoshye, ubucucike buke n’imikorere myiza yo gukingira ubushyuhe. Ubu buryo bwongerwa mu buryo butaziguye ku buryo bwo gukingira, kugira ngo agace gakingira gakozwe no gukingira igitambaro gafite ubushobozi bwo gukingira ubushyuhe. Uretse kuba gafite amavuta make kandi gafite ubucucike buke, kongeramo 5% (wt) bishobora kongera umusaruro urangiye ho 25% kugeza kuri 35%, bityo ntibizamure cyangwa ngo bigabanya igiciro cy’igitambaro.
Udupira tw’ibirahure tw’ubururu ni utubumbe tw’ubururu dufunze, twongerwa muri ubwo bururu kugira ngo habeho uburyo bwinshi bwo gukingira ubushyuhe bwigenga, bityo bikongera cyane uburyo bwo gukingira ubushyuhe n’amajwi, kandi bikagira uruhare runini mu gukingira ubushyuhe no kugabanya urusaku. Bituma ubwo bururu burushaho kutagira amazi, burwanya ihumana n’ubushyuhe. Ubuso bw’uturemangingo tw’ubururu butagira imiti burwanya ingese. Iyo ubwo bururu bukozwe, uduce tw’uturemangingo udusaro duto tw'ikirahure Bishyizwe hafi kugira ngo bigire imyenge mike, ku buryo ubuso bw'igitambaro bukora agace karinda ubushuhe n'ibintu byangiza, bigira uruhare runini mu kurinda.

Imiterere y'uruziga rw'amasaro y'ibirahure bidafite ubugari ituma agira ingaruka nziza zo gukwirakwira ku mbaraga z'uruvange n'umuvuduko. Kubishyira mu gipfundikizo bishobora kongera ubudahangarwa bw'uruvange rw'uruvange kandi bishobora no kugabanya kwaguka no guhindagurika kw'uruvange rw'umuvuduko.

Ingaruka nziza zo kwera no gutwikira. Ifu yera igira ingaruka nziza zo kwera kurusha ibara risanzwe, igabanya neza ingano y'ibindi bikoresho bihenze byo gusora n'amabara (ugereranije na dioxyde ya titanium, ingano y'amabara magufi ni 1/5 gusa). Yongera neza uburyo irangi rifatana. Imiterere mike y'amabara magufi y'ibirahure bituma resin nyinshi igira uruhare mu ikorwa rya firime, bityo yongera uburyo irangi rifatana inshuro 3 kugeza kuri 4.

Kongeraho 5% by'udupira duto bishobora gutuma ubucucike bw'igitambaro buva kuri 1.30 bukagera munsi ya 1.0, bityo bigabanura cyane uburemere bw'igitambaro kandi hirindwa ko igitambaro cyo ku rukuta gicika.

Udupira duto dufite ingaruka nziza ku mirasire ya ultraviolet, bikarinda ko irangi rihinduka umuhondo no gusaza.

Ubushyuhe bwinshi bw'udupira duto (microbeads) butuma ubushyuhe bw'igitambaro burushaho gukomera kandi bukagira uruhare rwiza mu gukumira inkongi. Uduce tw'udupira duto (microbeads) tugira uruhare mu miterere y'udupira, kandi imbaraga zo gukururana ni nto, ibyo bikaba bishobora kongera imikorere y'igitambaro no gutuma inyubako irushaho koroha.

Inama zo gukoresha: Ingano rusange yo kongeramo ni 10% by'uburemere bwose. Udupira duto dutunganywa ku buso kandi dufite ubucucike buke, bigatuma irangi rishobora kwiyongera mu buryo bw'ubushyuhe no kureremba mu gihe cyo kubika. Turasaba kongera ubushyuhe bw'ibanze bw'irangi (mu kongera ingano y'umubyimba ugenzura ubushyuhe buri hejuru ya 140KU), muri iki gihe, ikintu cyo kureremba ntikizabaho kuko ubushyuhe buri hasi cyane, kandi uduce twa buri kintu muri sisitemu turagabanuka mu bikorwa bitewe n'ubushyuhe bwinshi, ari na byo byiza mu kugenzura ubushyuhe. Turasaba cyane uburyo bukurikira bwo kongeramo: kubera ko udupira duto dufite inkuta ntoya kandi tudakomeye mu gukata, kugira ngo dukoreshe neza imiterere y'udupira duto, ni byiza gufata uburyo bwa nyuma bwo kongeramo, ni ukuvuga gushyira udupira duto ku mpera y'irangi. Kongeramo gukwirakwira hakoreshejwe ibikoresho byo gukangura hamwe n'umuvuduko muto n'imbaraga nke zo gukata uko bishoboka kose. Kubera ko imiterere y'udupira duto duto ifite ubushyuhe bwiza kandi ukutumvikana hagati yatwo atari gunini, biroroshye gukwirakwira. Ishobora gutoseshwa burundu mu gihe gito, gusa kongera igihe cyo gukangura kugira ngo ikwirakwizwe neza.

Udusaro tw’imikorobe ntitwinjizwa mu buryo bwa shimi kandi ntabwo turimo uburozi. Ariko, kubera uburemere bwatwo bworoshye cyane, tugomba kwitonda cyane mu gihe twongeramo. Turasaba uburyo bwo kongeramo intambwe ku yindi, ni ukuvuga ko ingano ya buri sosi ni 1/2 cy’udusaro tw’imikorobe dusigaye, kandi twongerwamo buhoro buhoro, ibyo bikaba byarinda utusaro tw’imikorobe kureremba mu kirere bigatuma gukwirakwira kw’utusaro kuzura neza.
