Nk’uko imibare ibigaragaza, mu Kuboza 2021. Ubushinwa buzaba bufite imodoka miliyoni 302.Imbere y’isoko ry’abaguzi ryagutse, irushanwa hagati y’imyenda itagaragara y’imodoka irashyuha.Ikigaragara muri iki gihe ni uko guhatanira amaherezo yo hasi gushingiye ku biciro, mu gihe amarushanwa yo mu rwego rwo hejuru ashingiye ku mbuga za tekiniki.
Ibanga rya firime ikingira hydrophobique (1)
Kuberako ibicuruzwa byiki gihe ari kimwe, intego yanyuma yintambara yibiciro igomba kuba iyo kugirira nabi uwo muhanganye igihumbi no gutakaza magana inani.Gusa dukurikije tekinoroji igezweho kugirango tumenye inzira yo gushiraho no gushyiraho itandukaniro ryibicuruzwa dushobora gufata amahirwe mashya kumasoko.
Witondere tekinolojiya mishya yimyenda yimyenda kandi ufate inganda
Igifuniko cyimodoka, nkuko twese tubizi, gifite anti-scratch, irwanya amarira, nibindi biranga.Ibi biranga bikomoka kumodoka ya TPU substrate.Igifuniko cyiza cyimodoka ya TPU kirinda irangi neza kandi gifite ubuzima burebure.Undi murimo wingenzi wigifuniko cyimodoka nukwisukura, kwikosora, no kumurika cyane.Iyi mikorere ikomoka ku gutwikira hejuru ya TPU substrate.Ubwiza bwurwo rwego ntibusobanura gusa umurimo ukomeye wo kwisukura, ariko kandi nimwe mubintu byingenzi bihinduka muguhitamo isura yimodoka.Kubera iyo mpamvu, mugihe abaguzi baguze imyenda yimodoka kugirango bagumane isura yimodoka ya buri munsi, bitondera cyane imikorere yimyenda yo kwisukura.
Hariho itandukaniro riri hagati yo kwegerana nintera, kandi hydrophobic coating car capage yimodoka nukuri!
Imodoka nyinshi zitagaragara zitwikirwa zamamaza ko zifite umurimo wo kwisukura, ariko hariho ikibazo cyibibazo byingaruka.Ndetse n'amaduka menshi ya firime akeneye ubufasha kubyumva.Hano hari hydrophilique na hydrophobique yubwoko bwimodoka zitagaragara.Uyu munsi tugiye kuvuga kuri iri tandukaniro ryimbitse.
Bamwe mu bafite imodoka basanze mugikorwa cyo kuyikoresha nyuma yo guhura nimvura mugihe amazi azimye, ibibara byimvura yumukara cyangwa byera bizagaragara hejuru yimodoka itagaragara, bisa nifoto iri hepfo.
Nk’uko abari mu nganda babitangaza, impamvu nyamukuru yabiteye ni uko ikote ry’ikinyabiziga ridafite hydrophobique, bityo ibitonyanga by’amazi bikomera ku ikoti ry’imodoka kandi ntibitemba.Iyo amazi azimye, ibintu bisigaye bigira ibimenyetso byamazi, ibara ryamazi, hamwe nimvura.Tuvuge ko ubwitonzi bwo gutwikira budahagije.Muri icyo gihe, ibintu bisigaye nabyo bizinjira imbere muri membrane, bivamo imvura idashobora guhanagurwa cyangwa gukaraba, bikagabanya cyane ubuzima bwumurimo.
Ikoti yimodoka itwikiriye hydrophilique cyangwa hydrophobique?Nigute ibyo bitandukanya?
Mbere yo kwiga gutandukanya, tugomba mbere na mbere kumva igitekerezo cya hydrophilique na hydrophobique.
Microscopically, inguni ihuza hagati yigitonyanga cyamazi nubuso bwa membrane igena niba ari hydrophilique cyangwa hydrophobique.Inguni yo guhuza munsi ya 90 ° ni hydrophilique, inguni yo guhuza munsi ya 10 ° ni super hydrophilique, inguni ihuza abantu barenga 90 ° ni hydrophobique, naho impande zirenga 150 ° ni Super-hydrophobique.
Ibanga rya firime irinda hydrophobique (2) Kubijyanye no gutwikira igifuniko cyimodoka, niba hagomba gukorwa ingaruka zo kwisukura.Ni igisubizo gishoboka mubitekerezo, haba mugutezimbere hydrophobicity cyangwa hydrophobicity.Ingaruka yo kwisukura, kurundi ruhande, nibyiza gusa mugihe inguni ya hydrophilique ihuza munsi ya dogere 10, kandi hejuru ya hydrophobique ntigomba kwiyongera cyane kugirango habeho ingaruka nziza yo kwisukura.
Ibigo bimwe byakoze ibizamini by'imibare.Imyenda myinshi yimodoka kumasoko uyumunsi ni hydrophilique.Muri icyo gihe, byavumbuwe ko amakote y’imodoka yo muri iki gihe adashobora kugera kuri hydrophilique ya 10 °, kandi igice kinini cy’itumanaho ni 80 ° -85 °, aho impande zose zaba ari 75 °.
Nkigisubizo, ingaruka zo kwisukura yimodoka ya hydrophilique yimodoka irashobora kunozwa.Ni ukubera ko, nyuma yo kwomekaho hydrophilique itagaragara yimodoka, ubuso bwumubiri uhuye n imyanda bwiyongera muminsi yimvura, bikongerera amahirwe yo kwanduza no kwizirika hejuru y irangi, bigoye kuyisukura.
Abahanga bavuga ko uburyo bwo gukora hydrophilique butwikiriye bworoshye kandi buhenze kuruta ubw'amazi ya hydrophobique.Ibinyuranye na byo, hydrophobic coatings ikenera gushyiramo nano-hydrophobique oleophobic oleophobic, kandi ibisabwa mubikorwa birakomeye, ibyo ibigo byinshi ntibishobora kuzuza - bityo ikoti ryamazi ryamamaye.
Nyamara, igifuniko cyimodoka ya hydrophobique gifite ibyiza byihariye mugukemura ikibazo cyingaruka mbi yo kwisukura yimodoka zitagaragara kuko gutwika hydrophobique bigira ingaruka nkibibabi bya lotus.
Ibanga rya hydrophobique ya firime ikingira (3) Ingaruka yamababi ya Lotusi nuko nyuma yimvura, imitekerereze ikaze ya microscopique morphologie hamwe nigishashara cya epidermal hejuru yibibabi bya lotus birinda ibitonyanga byamazi gukwirakwira no kwangirika hejuru yibibabi, ahubwo bigatera ibitonyanga byamazi.Mugihe kimwe, ikuraho umukungugu na grime mumababi.
Ibanga rya firime ikingira hydrophobique (4)
Iyo ishyizwe ku ikoti ry'imodoka ya hydrophobique, herekanwa ko iyo amazi y'imvura aguye hejuru ya membrane, ikora ibitonyanga byamazi bitewe nubushyuhe bwubuso bwa hydrophobique.Ibitonyanga byamazi bizanyerera gusa hanyuma bigende hejuru ya membrane kubera uburemere.Kuzunguruka ibitonyanga byamazi birashobora kandi gukuramo ivumbi nigitonyanga hejuru yikibabi, bikagira ingaruka zo kwisukura.
Nigute dushobora gutandukanya niba gutwikira imodoka ari hydrophilique cyangwa hydrophobique?
Hariho inzira ebyiri nyamukuru:
1. Koresha ibikoresho byumwuga kugirango upime inguni.
2.Amazi azunguruka hejuru ya membrane kugirango akore isuzuma ryibanze.
Ibitonyanga byamazi byoroshye adsorb hejuru ya hydrophilique isanzwe.Ibitonyanga byamazi ntibishobora kuboneka hejuru ya hydrophilique.Ubuso bwonyine buzaba butose;ibitonyanga byamazi bizatera imbere hejuru ya hydrophobique, ariko bizatemba hamwe nuburemere., guhuza no gutembera kure, ubuso buguma bwumutse, kandi ingaruka ya super-hydrophobique irakomeye.
Nkigisubizo, iyo amazi ashyizwe kuri kote yimodoka, ikora amasaro yatatanye, biragoye gutemba, kandi ibyinshi muri byo ni hydrophilique.Ibitonyanga byamazi birahurira hamwe bikanyerera, bikerekana ubuso, butwikiriwe cyane na hydrophobique.
