Urumva ihame ryimikorere ya electrostatike polarisiyasi yimyenda yashonze

N muri masike ya N95 yerekana kutarwanya amavuta, ni ukuvuga kutarwanya amavuta; Umubare ugereranya uburyo bwo kuyungurura iyo ugeragejwe hamwe na micron 0.3, naho 95 bivuze ko ishobora gushungura byibuze 95% byuduce duto nka virusi yibicurane, ivumbi, amabyi, igihu, numwotsi. Kimwe na masike yo kubaga kwa muganga, imiterere yingenzi ya masike ya N95 igizwe nibice bitatu: hejuru yubushuhe butagaragara neza, gushungura hagati hamwe na adsorption, hamwe nuruhu rwimbere. Ibikoresho bibisi bikoreshwa nuburemere buke bwa polypropilene imyenda ya meltblown. Kubera ko byose ari imyenda yashonze, niyihe mpamvu zituma imikorere yo kuyungurura itujuje ubuziranenge?

Impamvu zo kutayungurura kutujuje ubuziranenge bwa mask meltblown umwenda

Imikorere ya filteri yimyenda idashushanyije ubwayo iri munsi ya 70% gusa. Ntabwo bihagije kwishingikiriza gusa kumikorere ya barrière ya fibre igizwe na fibre-fibre-fibre igizwe na fibre ultrafine fibre fibre fibre nziza, utuntu duto, hamwe nubushake buke. Bitabaye ibyo, kongera uburemere nubunini bwibintu bizongera cyane kuyungurura. Ibikoresho byo gushungura rero byashizwemo muri rusange byongeramo amashanyarazi ya electrostatike kumyenda yashongeshejwe binyuze muburyo bwa polarisiyasi ya electrostatike, ukoresheje uburyo bwa electrostatike kugirango uzamure neza kuyungurura, ushobora kugera kuri 99.9% kugeza kuri 99,99%. Nukuvuga, kugera kuri N95 bisanzwe cyangwa hejuru.

Ihame ryo gushonga imyenda ya fibre iyungurura

Umwenda ushonga wakoreshejwe kuri masike ya N95 usanzwe ufata uduce dukoresheje ingaruka ebyiri za barrière ya mashini na adsorption ya electrostatike. Inzitizi ya mashini ifitanye isano rya bugufi n'imiterere n'imiterere y'ibikoresho: iyo umwenda ushonga ushizwemo na corona hamwe na voltage ya volt magana menshi kugeza ku bihumbi byinshi, fibre ikwirakwira mumurongo wa pore kubera kwanga amashanyarazi, kandi ubunini buri hagati ya fibre nini cyane kuruta ivumbi, bityo bikagira imiterere ifunguye. Iyo umukungugu unyuze mumashanyarazi yashizwemo, ingaruka za electrostatike ntizikurura gusa uduce twinshi twumukungugu, ariko kandi zifata ibice bitagira aho bibogamiye binyuze mumashanyarazi ya electrostatike. Iyo ubushobozi bwa electrostatike bushoboka bwibintu, niko ubwinshi bwubwinshi bwibintu, niko ingingo nyinshi itwara, ningaruka za electrostatike. Gusohora Corona birashobora kunoza cyane imikorere yo kuyungurura imyenda ya polypropilene yashonga. Ongeramo ibice bya tourmaline birashobora kunoza neza polarizabilite, kongera ubushobozi bwo kuyungurura, kugabanya kuyungurura, kongera ubwinshi bwumuriro wa fibre, no kongera ubushobozi bwo kubika ibicuruzwa byurubuga rwa fibre.

Ongeraho 6% tourmaline kuri electrode ifite ingaruka nziza muri rusange. Ibikoresho byinshi cyane birashobora kwongera ingendo no kutabogama kwabatwara. Amashanyarazi yamashanyarazi agomba kugira nanometero cyangwa micro ya nanometero yubunini hamwe nuburinganire. Ibikoresho byiza bya polar birashobora kunoza imikorere yizunguruka bitagize ingaruka kuri nozzle, kongera imbaraga zo kuyungurura, kurwanya iyangirika rya electrostatike, kugabanya ubukana bwikirere, kongera ubwinshi bwimbitse hamwe nuburebure bwifatwa ryumuriro, byongera amahirwe menshi yandi mafranga yaguye mumashanyarazi, kandi bikagumya guhunga imitego yabatwara ibicuruzwa cyangwa kutabogama, bityo bikadindiza kwangirika.

Gushonga inzira ya electrostatike ya polarisiyasi

Inzira yo gushonga ya electrostatike isohoka ikubiyemo kongeramo ibikoresho bidakoreshwa nka tourmaline, dioxyde de silicon, na fosifate ya zirconium kuri PP polypropilene polymer mbere. Noneho, mbere yo kuzinga umwenda, ibikoresho byashongeshejwe byashizwemo numurongo umwe cyangwa byinshi byo gusohora corona ukoresheje urushinge rumeze nka electrode ya voltage ya 35-50KV ikorwa na generator ya electrostatike. Iyo hashyizweho ingufu nyinshi, umwuka uri munsi yinshinge zitanga corona ionisation, bikavamo gusenyuka kwaho. Abatwara ibicuruzwa bishyirwa hejuru yigitambara cyashongeshejwe binyuze mumashanyarazi, kandi bamwe muribo bazafatwa numutego wibice bya mama bihagaze, bigatuma umwenda ushonga ushonga ibikoresho bya filteri ya electrode. Umuvuduko muri iki gikorwa cya corona uri hasi gato ugereranije no gusohora hamwe n’umuvuduko mwinshi wa 200Kv, bigatuma umusaruro wa ozone ugabanuka. Ingaruka zo kwishyuza intera no kwishyuza voltage ntangaruka. Mugihe intera yo kwishyuza yiyongera, umubare wamafaranga wafashwe nibikoresho uragabanuka.

Imashanyarazi yashizwemo amashanyarazi irakenewe

1. Igice kimwe cyibikoresho byashongeshejwe

2. Amashanyarazi yamashanyarazi

3. Amaseti ane yibikoresho bisohora amashanyarazi menshi

4. Gukata ibikoresho

Imyenda ya meltblown igomba kubikwa idafite amazi kandi idafite amazi

Mugihe cy'ubushyuhe busanzwe n'ubushuhe, PP yashonga ibikoresho bya polarizable bifite ububiko bwiza bwo kubika neza. Nyamara, iyo icyitegererezo kiri ahantu hafite ubuhehere bwinshi, igihombo kinini kibaho bitewe ningaruka zindishyi zamatsinda ya polar muri molekile zamazi hamwe nuduce twa anisotropique mukirere ku byishyurwa kuri fibre. Amafaranga yagabanutse hamwe no kongera ubushuhe kandi byihuta. Kubwibyo, mugihe cyo gutwara no kubika, umwenda ushonga ugomba kubikwa neza kandi ukirinda guhura n’ibidukikije byinshi. Niba itabitswe neza, masike yakozwe bizakomeza kugorana kubahiriza ibipimo.

Dongguan Liansheng Ntabwo Yubatswe Ikoranabuhanga Co, Ltd.yashinzwe muri Gicurasi 2020.Ni uruganda runini rutunganya imyenda rudahuza ubushakashatsi niterambere, umusaruro, no kugurisha. Irashobora gutanga amabara atandukanye ya PP spunbond idoda idoda hamwe n'ubugari bwa metero 3.2 kuva kuri garama 9 kugeza kuri garama 300.
