Imashini ikuraho ibara ry'amazi yanduye ikemura ibibazo byo gutunganya amazi yanduye mu mujyi

Uburyo amazi yanduye yo mu mujyi agoye cyane ni bwo bugaragara cyane. Amavuta atwarwa n'amazi yanduye azajya ahinduka nk'amata, ifuro rikorwa n'isabune rizagaragara nk'ubururu n'icyatsi kibisi, kandi imyanda ivamo akenshi iba umukara wijimye. Ubu buryo bw'amabara menshi butanga ibisabwa byinshi ku ibikoresho byo gukuraho ibara ry'amazi yanduye: Igomba kugira imirimo myinshi nko gukuramo imyanda, gukurura amazi no kugabanya ogisijeni icyarimwe. Raporo y'igerageza ry'uruganda rutunganya imyanda rwo muri Nanjing igaragaza ko urwego rw'ihindagurika rya chromaticity ry'ingufu zarwo rushobora kugera kuri dogere 50-300, kandi chromaticity y'imyanda itunganywa n'ibikoresho bisanzwe byo gukuraho ibara ry'amazi y'imyanda biracyagoye kuyituza munsi ya dogere 30.

Imashini zigezweho zo gukuraho ibara ry'amazi yanduye Bageze ku ntambwe nziza binyuze mu miterere y’imiterere ya molekile. Dufashe urugero rwa polima ya dicyandiamide-formaldehyde yahinduwe, amatsinda ya amine na hydroxyl ku ruhererekane rwa molekile yayo akora ingaruka zo guhuza: itsinda rya amine rifata amarangi ya anionic binyuze mu bikorwa bya electrostatic, naho itsinda rya hydroxyl rigashyiramo iyoni z'icyuma kugira ngo rikureho ibara ry'icyuma. Amakuru nyayo agaragaza ko igipimo cyo gukuraho chromaticity y'amazi yanduye yo mu mujyi cyariyongereye kigera ku kigero kirenga 92%, kandi igipimo cyo gukuraho alum flake sedimentation cyariyongereyeho hafi 25%. Ikigaragara kurushaho ni uko iyi decolorizer y'amazi yanduye iracyashobora gukomeza gukora cyane mu gihe cy'ubushyuhe buke.

Ukurikije uburyo bwose bwo gutunganya amazi, iyi “decolorizer” nshya izana impinduka nyinshi. Mu bijyanye n'imikorere myiza yo gutunganya amazi, nyuma y'uko uruganda rw'amazi rwasubijwe rukoresha “composite” igabanya ibara ry'amazi yanduye, igihe cyo kubika amazi yanduye cyagabanijwe kuva ku minota 3 kugeza ku masegonda 90; mu bijyanye n'ikiguzi cyo gukora, ikiguzi cy'imiti kuri toni y'amazi cyagabanutseho hafi 18%, kandi umusaruro w'amazi wagabanutseho 15%; mu bijyanye no kubungabunga ibidukikije, ingano ya monomer isigaye yagenzuwe iri munsi ya 0.1 mg/L, iri munsi cyane y'ibipimo by'inganda. Cyane cyane iyo itunganya imyanda ivanze, ifite ubushobozi bwiza bwo kugabanya ihindagurika ry'amazi bitewe n'imvura nyinshi.

Ubushakashatsi buriho bwibanze ku nzira eshatu nshya: imashini zikuraho ibara ry'amazi yanduye zikoresha fotokalisiyumu zishobora kwiyangiza nyuma yo kuvurwa kugira ngo hirindwe umwanda wa kabiri; imashini zikuraho ibara ry'amazi yanduye zikoresha ikoranabuhanga rituma ahinduka mu buryo bwikora hakurikijwe ubushyuhe bw'amazi; hamwe n'imashini ziyongera ku bushyuhe.ibikoresho byo gukuraho ibara ry'amazi yanduye guhuza ubushobozi bwo kwangiza mikorobe. Ubu bushya bukomeje gutuma amazi yanduye yo mu mujyi atunganywa neza kandi akagera ku cyerekezo cyiza kandi cyita ku bidukikije.
