Niki gushonga byavanze imyenda idoda

Gushonga imyenda idashushanyijeho ni ubwoko bushya bwibikoresho byimyenda bikozwe mubikoresho bya polymer bihanitse binyuze mubikorwa nko gutegura ibikoresho bibisi, gushonga ubushyuhe bwinshi, gushiramo imiti, gukonjesha no gukomera. Ugereranije n'urushinge gakondo rwakubiswe imyenda idoda, imyenda yashonze idashushanyijeho ifite fibre nziza kandi ihuriweho, hamwe no guhumeka hamwe no kurwanya amazi, bigatuma iba icyerekezo cyingenzi cyiterambere mubijyanye nimyenda yimyenda.

Ibiranga gushonga byavanze imyenda idoda

1. Imikorere yo kuyungurura neza, ishobora guhagarika neza ikwirakwizwa ryibintu byangiza nkibice, bagiteri, virusi, nibindi;

2. Byoroheje kandi byiza, hamwe no guhumeka neza, byoroshye kwambara, kandi nta reaction ya allergique;

3.

4. Biroroshye gutunganya, bishoboye gukata, kudoda, gukanda bishyushye, kumurika no kuvura ukurikije ibikenewe bitandukanye.

Gukoresha gushonga byavanze imyenda idoda

Imyenda yashongeshejwe idoda idoda ifite uburyo butandukanye bwo gusaba, kandi yakorewe ubushakashatsi mubice nkubuvuzi, isuku, nibikoresho byo munzu. Ibice byingenzi bisabwa ni ibi bikurikira:

1.

2.

3. Ibikoresho byo kuyungurura: Gushonga imyenda idashushe irashobora gukorwa mubikoresho byo kuyungurura umwuka, amazi, namavuta, bishobora gukuraho neza uduce two mu kirere no kugabanya ibyuka bihumanya. Irashobora kandi gukoreshwa mumirima nko kuyungurura imashini no kuyungurura amazi yo kunywa.

Gushonga guhuha bitari imyenda ni ibikoresho byiza

Imyenda yashongeshejwe idoda idoze ifite ubuso bunini bwihariye nubuso buto (ubunini bwa pore ≤ 20) μ m) Umubyimba mwinshi (≥ 75%) nibindi biranga. Niba impuzandengo ya diametre ari 3 μ Ubuso bwihariye bwubuso bwashongeshejwe bwimyenda idahwitse, bihwanye nuburinganire bwa fibre ya 0.0638 dtex (hamwe na fibre ingana na 0.058 denier), igera kuri cm 14617 cm2 / g, mugihe impuzandengo ya diametre 15.3 μ Ubuso bwihariye bwa fibre spunbond idafite uburinganire bwa cm 1,2 dtx 1.5.

Bitewe nubushuhe buto cyane bwumuriro wumwuka ugereranije na fibre zisanzwe, umwuka uri mumyobo yimyenda yashonze uduhuzu utagabanije bigabanya ubushyuhe bwumuriro. Gutakaza ubushyuhe byanduzwa binyuze muri fibre yibikoresho byashongeshejwe bitarimo ubudodo ni bike, kandi ikirere gihagaze neza hejuru ya fibre itabarika ya ultrafine irinda ihererekanyabubasha riterwa no gutembera kwumwuka, bigatuma bigira ingaruka nziza kandi zishyuha.

Polypropilene (PP) fibre ni ubwoko bwibikoresho bya fibre bihari bifite ubushyuhe buke cyane. Gushonga byashushanyijeho ubushyuhe bwumuriro bikozwe muri fibre ya PP nyuma yubuvuzi budasanzwe bufite imikorere yubushyuhe bwumuriro inshuro 1.5 ugereranije no hasi yikubye inshuro 15 iy'ipamba isanzwe. By'umwihariko bikwiriye gukora imyenda yo gusiganwa ku maguru, imyenda yo kuzamuka imisozi, ibitanda, imifuka yo kuryama, imyenda y'imbere y’umuriro, gants, inkweto, n'ibindi. Ibicuruzwa bifite ingano ya 65-200g / m2 byakoreshejwe mu gukora imyenda ishyushye ku basirikare bo mu turere dukonje.

Nigute ushobora kunonosora imikorere ya filteri yimyenda idashushanyije

Gushonga imyenda idoda, nkibikoresho byingenzi bya masike yubuvuzi, uburyo bwo kuyungurura bigira ingaruka muburyo bwo kurinda mask. Hariho ibintu byinshi bigira ingaruka kumikorere ya filteri yimyenda idashushanyijeho imyenda idahwitse, nkuburinganire bwa fibre umurongo, imiterere ya fibre mesh, ubunini, nubucucike. Nkibikoresho byo kuyungurura ikirere kubitwikiriye, niba ibikoresho bifunze cyane, imyenge ni nto cyane, kandi guhumeka guhumeka ni hejuru cyane, uyikoresha ntashobora guhumeka umwuka neza, kandi mask itakaza agaciro kayo kugirango ikoreshwe. Ibi birasaba ko ibikoresho byo kuyungurura bidatezimbere gusa kuyungurura, ahubwo binagabanya kurwanya ubuhumekero bwabo, ibyo bikaba bivuguruzanya hagati yubuhumekero no gukora neza. Uburyo bwo kuvura amashanyarazi ya electrostatike nuburyo bwiza bwo gukemura amakimbirane hagati yubuhumekero no gukora neza.

Inzitizi ya mashini

Impuzandengo ya fibre ya fibre ya polypropilene yashonga umwenda uhuha ni 2-5 μ m. Ingano ya parike irenze 5 mu kirere μ Ibitonyanga bya m birashobora guhagarikwa nigitambara gishonga; Iyo umurambararo wumukungugu mwiza uri munsi ya 3 μ Kuri m, bitewe nuburyo butunguranye bwa fibre hamwe nuruvange rwimyenda yashonze, hashyirwaho fibre ya fibre ifite imiyoboro myinshi yagoramye. Iyo uduce tunyuze muburyo butandukanye bwimiyoboro cyangwa inzira, umukungugu mwiza wamamajwe hejuru ya fibre ukoresheje imashini zungurura van der Waals; Iyo ingano yingirakamaro hamwe n umuvuduko wumuyaga byombi ari binini, umwuka wo mu kirere wegera ibintu byungururwa hanyuma ukazenguruka kubera inzitizi, mugihe ibice bitandukana kumurongo bitewe nubusembure kandi bigahura neza na fibre igomba gufatwa; Iyo ingano yingirakamaro ari nto kandi umuvuduko ukabije ni muto, ibice bigenda bikwirakwira bitewe nigikorwa cya Brownian hanyuma bigahura na fibre igomba gufatwa.

Amashanyarazi ya electrostatike

Electrostatic adsorption bivuga gufata ibice byingufu za Coulomb ya fibre yishyuwe (electret) mugihe fibre yibikoresho byayungurujwe. Iyo umukungugu, bagiteri, virusi, nibindi bice byanyuze muyungurura, imbaraga za electrostatike ntizikurura gusa uduce duto twashizwemo, ariko kandi zifata uduce duto twa polarisiyumu tutabogamye dukoresheje ingaruka zo kwinjiza amashanyarazi. Mugihe ubushobozi bwa electrostatike bwiyongera, ingaruka za electrostatike ya adsorption iba ikomeye.
