Nigute ushobora kunoza imikorere ya filteri yimyenda yashonze?

Nkibikoresho byibanze bya masike yubuvuzi, kuyungurura imikorere yimyenda ya elegitoronike bigira ingaruka muburyo bwo kurinda masike. Hariho ibintu byinshi bigira ingaruka kumikorere yo kuyungurura imyenda ya meltblown, nkubucucike bwumurongo wa fibre, imiterere ya fibre mesh, ubunini, nubucucike.

Ariko, nka anibikoresho byo kuyungurura ikirerekuri masike, niba ibikoresho bifunze cyane, imyenge ni nto cyane, kandi irwanya guhumeka ni ndende cyane, uyikoresha ntashobora guhumeka neza umwuka, kandi mask yataye agaciro.

Ibi birasaba ibikoresho byo kuyungurura ntabwo bizamura gusa kuyungurura, ahubwo binagabanya imbaraga zo guhumeka neza bishoboka, kandi kurwanya ubuhumekero no kuyungurura ni ibintu bivuguruzanya. Uburyo bwo kuvura amashanyarazi ya electrostatike nuburyo bwiza bwo gukemura amakimbirane hagati yubuhumekero no gukora neza.

Uburyo bwo kuyungurura imyenda ya meltblown

Muburyo bwo kuyungurura ibikoresho byashongeshejwe byungururwa, uburyo busanzwe buzwi burimo gukwirakwiza Brownian, guhagarika, kugongana kutagira imbaraga, gutuza imbaraga, hamwe na adsorption ya electrostatike. Bitewe nuko amahame ane ya mbere yose ari inzitizi zubukanishi, uburyo bwo kuyungurura imyenda yashonze irashobora kuvugwa muri make nkinzitizi zumukanishi hamwe na adsorption ya electrostatike.

Inzitizi ya mashini

Impuzandengo ya fibre diameter yapolipropilene imyenda yashongani 2-5 μ m, kandi ibitonyanga bifite ubunini burenze 5 μ m mu kirere birashobora guhagarikwa nigitambara gishonga.

Iyo umurambararo wumukungugu mwiza uri munsi ya 3 μ m, fibre iri mumyenda yashonze itunganijwe kandi igahuza kugirango ikore umuyoboro munini uhetamye fibre filteri. Iyo ibice byanyuze muburyo butandukanye bwimiyoboro igoramye cyangwa inzira, umukungugu mwiza wamamajwe hejuru ya fibre nimbaraga za filtration ya van der Waals.

Iyo ingano yingirakamaro hamwe n umuvuduko wumuyaga byombi ari binini, umwuka wo mu kirere wegera ibintu byungurura kandi bikabuzwa, bigatuma bitembera hirya no hino, mugihe ibice bitandukana kumurongo bitewe nubusembure kandi bigahura neza na fibre, bigafatwa.

Iyo ingano yingirakamaro ari nto kandi umuvuduko wikigereranyo ukaba muke, ibice bikwirakwira bitewe nigikorwa cya Brownian hanyuma bigahura na fibre igomba gufatwa.

Amashanyarazi ya electrostatike

Electrostatic adsorption bivuga gufata ibice byingufu za Coulomb ya fibre zishyizwemo (polarizasiyo) mugihe fibre yibikoresho byayungurujwe. Iyo umukungugu, bagiteri, virusi nibindi bice byanyuze muyungurura, imbaraga za electrostatike ntizishobora gukurura gusa ibice byashizwemo imbaraga, ariko kandi zishobora no gufata uduce duto duto duto duto duto tubikesheje ingaruka zo kwinjiza amashanyarazi. Mugihe ubushobozi bwa electrostatike bwiyongera, ingaruka za electrostatike ya adsorption iba ikomeye.

Intangiriro yuburyo bwo gukwirakwiza amashanyarazi

Bitewe no kuyungurura imikorere yimyenda isanzwe idashushanyijeho imyenda iri munsi ya 70%, ishingiye gusa kumikorere ya barrière ya mikoranike yibice bitatu bigize fibre nziza hamwe na fibre nziza, ubusa buto, hamwe nububasha bukabije butangwa na fibre ultrafine fibre ntihagije. Kubwibyo, ibikoresho byo kuyungurura gushonga muri rusange byongera ingaruka zumuriro wa electrostatike kumyenda ya elegitoronike hifashishijwe ikoranabuhanga rya electrostatike polarisation, ukoresheje uburyo bwa electrostatike kugirango urusheho kuyungurura, bigatuma bishoboka kugera kuri 99.9% kugeza kuri 99,99%. Igice gito cyane gishobora kuba cyujuje ibipimo byateganijwe, kandi kurwanya ubuhumekero nabyo ni bike.

Kugeza ubu, uburyo nyamukuru bwa polarisiyumu ya electrostatike harimo electrospinning, gusohora corona, guterana kwatewe na polarisiyasi, polarisiyumu yumuriro, hamwe n’ibisasu bito bito bya electron. Muri byo, gusohora corona kuri ubu nuburyo bwiza bwa electrostatike polarisation.

Uburyo bwo gusohora corona nuburyo bwo kwishyuza ibintu bishonga binyuze mumurongo umwe cyangwa nyinshi za electrode zifite inshinge (voltage muri rusange 5-10KV) ya generator ya electrostatike mbere yo guhinduranya fibre fibre mesh. Iyo hashyizweho ingufu nyinshi, umwuka uri munsi yinshinge zitanga corona ionisation, bikavamo gusenyuka kwaho. Abatwara ibintu bashyizwe hejuru yumwenda ushonga munsi yumuriro wamashanyarazi, kandi abatwara bamwe bazafatwa numutego wibice byumubyeyi uhagaze byimbitse hejuru yubutaka, bigatuma umwenda ushonga ibintu byungurura umubiri uhagaze.

Kongera ubwinshi bwimyenda yimyenda ya elegitoronike irashobora kuboneka hakoreshejwe uburyo bwo gusohora corona uburyo bwo kuvura amashanyarazi ya electrostatike, ariko kugirango hirindwe kwangirika kwububiko bwa electrostatike, ibice hamwe nimiterere yibikoresho bya elegitoronike byashongeshejwe bigomba kuba byiza kugirango bishyure. Inzira yo kunoza ubushobozi bwo kubika ibikoresho bya electret irashobora kugerwaho mugutangiza inyongeramusaruro hamwe nububiko bwamafaranga kugirango habeho imitego yishyurwa no gufata amafaranga.

Kubwibyo, ugereranije numurongo usanzwe ushonga, umusaruro wibikoresho byashongeshejwe kugirango ushungurwe mu kirere bisaba ko hongerwaho ibikoresho byoherejwe na electrostatike y’amashanyarazi mu murongo w’ibicuruzwa, no kongeramo ibishushanyo mbonera bya polar nkibice bya turmaline ku bicuruzwa fatizo bya polipropilene (PP).

Ibintu nyamukuru bigira ingaruka ku ngaruka zo kuvura electrospinning ku mwenda ushonga

1. Ibisabwa byo kwishyuza: igihe cyo kwishyuza, intera yo kwishyuza, kwishyuza voltage;

2. Ubunini;

3. Ibikoresho byamashanyarazi.
