Uburyo bwo gushonga ni uburyo bwo gutegura fibre urambuye byihuse polymer ushonga binyuze mubushyuhe bwinshi kandi byihuta byumuyaga. Ibice bya polimeri birashyuha kandi bigashyirwaho igitutu muburyo bwashongeshejwe na extruder, hanyuma ukanyura mumurongo wo gukwirakwiza gushonga kugirango ugere kumwobo wa nozzle kumpera yimbere ya nozzle. Nyuma yo gukuramo, barushijeho kunonosorwa barambura ibintu bibiri bihuza umuvuduko mwinshi hamwe nubushyuhe bwo hejuru. Fibre itunganijwe irakonjeshwa kandi igakomera ku gikoresho cyumwenda wa mesh kugirango ikore umwenda ushonga udoda.
Gukomeza gushonga hifashishijwe ikoranabuhanga rudoda imyenda rimaze imyaka irenga 20 ritera imbere mubushinwa. Imirima yacyo ikoreshwa yagutse kuva kubatandukanya bateri, ibikoresho byo kuyungurura, ibikoresho bikurura amavuta, nibikoresho byokugera kubuvuzi, isuku, ubuvuzi, kurinda, nibindi bice. Ubuhanga bwacyo bwo gukora nabwo bwateye imbere kuva umusaruro umwe ushonga ugana icyerekezo kimwe. Muri byo, ibikoresho bya elegitoronike byashizwe mu buvuzi bwa elegitoroniki birashobora gukoreshwa cyane mu kweza ikirere mu bikoresho bya elegitoroniki, ibiryo, ibinyobwa, imiti, ikibuga cy’indege, amahoteri n’ahandi, ndetse na masike yo mu rwego rwo hejuru y’ubuvuzi, imashini zikora ivumbi ry’inganda n’abasivili, kubera imbaraga nke zazo za mbere, ubushobozi bwo gufata ivumbi, hamwe n’ubushobozi bwo kuyungurura.
Gushonga byashushanyijeho imyenda idakozwe mu bikoresho bya polypropilene (ubwoko bwimyenda ya ultra-nziza ya electrostatike fibre ishobora gufata umukungugu) bigira ingaruka kubintu nkubunini bwa fibre nubunini, bigira ingaruka kumyungurura. Ibice bya diametre zitandukanye byungururwa binyuze mumahame atandukanye, nkubunini bwibice, ingaruka, amahame yo gukwirakwiza biganisha kuri fibre, hamwe nuduce tumwe na tumwe tuyungururwa na fibre electrostatike binyuze mumahame yo gukurura electrostatike. Ikizamini cyo kuyungurura imikorere ikorwa munsi yubunini bwerekanwe nuburinganire, kandi ibipimo bitandukanye bizakoresha ibice byubunini butandukanye kugirango bipimishe. BFE ikunze gukoresha bacteri ya aerosol ya bacteri ifite impuzandengo ya diametre ya 3 μ m, mugihe PFE muri rusange ikoresha ibice bifite diameter ya sodium ya chloride ya 0.075 μ m. Gusa ukurikije uburyo bwo kuyungurura neza, PFE ifite ingaruka zisumba BFE.
Mu igeragezwa risanzwe rya masike ya KN95, ibice bifite diameter ya aerodinamike ya 0.3 μ m ikoreshwa nkigikoresho cyo kwipimisha, kubera ko ibice binini cyangwa bito kurenza iyi diameter byoroshye gufatwa na fibre fibre, mugihe ibice bifite ubunini buringaniye bwa 0.3 μ m bigoye kuyungurura. Nubwo virusi ari nto mu bunini, ntishobora gukwirakwira wenyine mu kirere. Bakenera ibitonyanga nuclei nkibitwara kugirango bitatanye mu kirere, byoroshye kuyungurura.
Intandaro yikoranabuhanga rya elegitoronike ni ukugera ku kuyungurura neza mugihe hagabanijwe kurwanya imyuka yubuhumekero, cyane cyane kuri N95 no hejuru yimyenda ya meltblown, imyenda ya VFE yo mu bwoko bwa meltblown, mubijyanye no gukora polar masterbatch, imikorere yibikoresho byashongeshejwe, ingaruka zuzunguruka zumurongo wa elegitoronike, cyane cyane kongeramo uburinganire bwa fibre. Kugera kuburwanya buke no gukora neza ni tekinoroji yibanze.
Ibintu bigira ingaruka kumiterere yimyenda yashonze
MFI y'ibikoresho bya polymer
Umwenda wa Meltblown, nkurwego rwiza rwa barrière ya masike, ni ibintu byiza cyane bigizwe na fibre nyinshi ihuza ultrafine fibre yashyizwe mubyerekezo bidasanzwe imbere. Dufashe PP nk'urugero, hejuru ya MFI, niko insinga nziza yakuwe mugihe cyo gutunganya gushonga, kandi nibikorwa byiza byo kuyungurura.
Inguni y'indege ishyushye
Inguni yo guterwa umwuka ushushe cyane cyane ingaruka zo kurambura na fibre morphologie. Inguni ntoya izamura ishingwa rya fibre fibre iringaniye mumigezi myiza, bikavamo uburinganire buke bwimyenda idoda. Niba inguni igana kuri 90 °, hazavamo umwuka utatanye cyane kandi uhindagurika cyane, ibyo bikaba bifasha gukwirakwiza ku buryo butunguranye fibre ku mwenda ukingiriza meshi, kandi imyenda ivamo gushonga izaba ifite imikorere myiza ya anisotropy.
Kuramo umuvuduko wo gukuramo
Mugihe cy'ubushyuhe buhoraho, igipimo cyo gusohora cya screw kigomba kubungabungwa murwego runaka: mbere yikintu gikomeye, umuvuduko wo gusohora byihuse, niko umubare nimbaraga byumwenda ushonga; Iyo agaciro gakomeye karenze, imbaraga zimyenda yashonze ziragabanuka mubyukuri, cyane cyane iyo MFI> 1000, bishobora guterwa no kurambura kudahagije kwa filamenti biterwa nigipimo kinini cyo kuvamo, bikaviramo kuzunguruka cyane no kugabanya fibre ihuza imigozi hejuru yigitambara, bigatuma imbaraga zigitambara zishonga.
Umuvuduko mwinshi wumuyaga nubushyuhe
Mubihe bimwe byubushyuhe, umuvuduko wa screw, hamwe no kwakira intera (DCD), umuvuduko mwinshi wumuyaga ushushe, ntoya ya fibre fibre, kandi ukuboko kworoshye kwumva imyenda idoda, bikaviramo fibre nyinshi, biganisha kumurongo wa fibre yuzuye, yoroshye, kandi ikomeye.
Kwakira intera (DCD)
Intera ndende cyane yo kwemerwa irashobora gutuma igabanuka ryimbaraga ndende kandi zinyuranye, kimwe no kunama imbaraga. Umwenda udoda ubudodo ufite imiterere ihindagurika, ishobora gutuma igabanuka ryogukora neza no kuyirwanya mugihe cyo gushonga.
Gushonga umutwe wububiko (indangagaciro ikomeye)
Ibikoresho byabitswe hamwe nuburyo bwo gushiraho ubushyuhe. Gukoresha ibyuma biciriritse biciriritse ahubwo bishobora kuvamo uduce duto duto tudashobora kubonwa namaso mugihe cyo kuyakoresha, gutunganya aperture ikabije, kutamenya neza, no gukora imashini itabanje kuvurwa neza. Gutera gutera kuringaniza, gukomera nabi, gutera umubyimba utaringaniye, no korohereza ibintu.
Kunywa hasi
Gutunganya ibipimo nkubunini bwikirere nigitutu cya net yo hasi
Umuvuduko mwinshi
Umuvuduko wumwenda wa mesh uratinda, uburemere bwimyenda yashonze ni ndende, kandi kuyungurura ni hejuru. Ibinyuranye na byo, bifite ukuri.
Igikoresho kinini
Ibipimo nka polarisiyasi ya voltage, igihe cya polarisiyasi, polarisiyasi ya molybdenum intera, hamwe nubushuhe bwibidukikije bya polarisiyasi byose bishobora kugira ingaruka kumiterere yo kuyungurura.
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.
