Igitambaro cyo mu bwoko bwa mask core – igitambaro cyashongeshejwe | JINHAOCHENG

Ipfuka igice cy'inyuma cy'umubiriigitambaro cyashongeshejweIbikoresho byo kuyungurura bikozwe muri fibre ya polypropylene superfine hamwe n’uburyo ikwirakwira mu buryo butunguranye, imiterere yayo, uburyo bworoshye, bworoshye n’ubw’umweru bungana na 0.5 kugeza kuri 1.0 mu m, uburyo fibre ikwirakwira mu buryo butunguranye kugira ngo itange amahirwe menshi yo guhuza ubushyuhe hagati ya fibre bityo bigatuma ibikoresho byo kuyungurura imyuka ishongeshwa bifite ubuso bunini bwihariye, ubwinshi bw’imyenge (75%) cyangwa burenga. Binyuze mu buryo bwo kuyungurura amashanyarazi menshi, ibicuruzwa bifite imiterere yo kudahangana n’ibintu, ubushobozi bwo gukora neza no kugira ivumbi rinini.

Ipfundo ry'agapfukamunwa

Igitambaro kidapfundikiye gishongeshejwe nk'ubwoko bushya bw'ibikoresho byo kuyungurura binoze cyane ni udupfukamunwa tw'umutima, ugereranije n'ibikoresho bisanzwe byo kuyungurura, kuyungurura umwuka no gusukura neza kugeza ku ntera y'inshuro ijana, ubu ni cyo gikwiriye cyane mu bikoresho byo kurinda ubuzima bw'ibinyabuzima (karubone ikoreshwa n'ibindi bisa nayo bishobora gukoreshwa mu bintu birinda, kurwanya bagiteri na virusi bidakoresheje uburyo bwo kuyungurura). Ivuka ryayo mu buryo butunguranye abaganga BAKORESHA agapfukamunwa k'imyaka ijana kavanyweho burundu. Uburinzi bw'abaganga muri rusange bugabanyijemo ibice bitatu hakurikijwe urwego rw'uburinzi. "Udupfukamunwa two kubaga" tw'ubururu bworoheje twambara kenshi dushobora gukoreshwa mu kurinda by'ibanze, cyane cyane mu kwirinda kwandura kwangiza udukoko turimo udukoko mu buzima bwa buri munsi no mu musaruro. Ingamba z'ingenzi zo kunoza ubushobozi bwo kurinda ni ukongeraho urwego rw'agapfukamunwa rukozwe mu gitambaro kidapfundikiye gishongeshejwe hagati ya gapfukamunwa.

Agace gakingira hagati muri mask (urwego rwa M mu magambo make) ni umwenda udashonga uvanze na polypropylene, kandi impande z'imbere n'inyuma za mask ni uduce dufunganye (urwego rwa S mu magambo make). Bitewe n'urwego rw'uburinzi rukenewe, agace kamwe kugeza kuri kenshi gashobora gushyirwa muri M. Niba ari mask yo mu rwego rwa 1, koresha urwego rwa M. Ku gikoresho cyo guhumeka cyo mu rwego rwa 3 nka N95, urwego rwa M rushobora gusaba urwego rutatu rw'umwenda udashonga uvanze na melt cyangwa urenzeho. Birumvikana ko uko urwego rwa M rurushaho kuba rwinshi, niko umwuka winjira mu ma mask uba mubi, ibicuruzwa byihariye bizaba bitandukanye.

Iyo dufunguye agapfukamunwa, tuzabona ibice bitatu biri hejuru, ari byo urwego rwa hygroscopic, urwego rw'ibanze rwa filter, n'urwego rw'amazi.

Igitambaro cyo gushonga gishongeshwa, kiri hagati mu gice cyo kuyungurura uduce twa mask, gishobora kuyungurura bagiteri, kikarinda ikwirakwira rya mikorobe. Igitambaro cyo gushonga gishongeshwa, igitambaro cyo gushonga gishongeshwa ahanini kijya kuri polypropylene nk'ibikoresho by'ibanze, umurambararo wa fibre ushobora kugera kuri mikoroni 1 ~ 5. Iyi migozi myiza cyane ifite imiterere yihariye ya capillarity yongera umubare n'ubuso bw'imigozi kuri buri gice, ku buryo igitambaro cyo gushonga gishongeshwa gifite ubushobozi bwiza bwo kuyungurura, kurinda, gukingira no kwinjiza amavuta. Gishobora gukoreshwa mu mwuka, mu bikoresho byo kuyungurura amazi, mu bikoresho byo kwitandukanya, mu bikoresho byo gushonga, mu bikoresho byo gushonga, mu bikoresho byo gushonga, mu bikoresho byo gushonga, mu bikoresho byo gushonga, mu bikoresho byo gushonga amavuta no mu bindi bice.

Gufata no gukurura

Igitambaro gishonga ni ubwoko bwa polypropylene ifite ubunini bwo gushonga, ikozwe mu migozi myinshi ivanze mu criss-cross mu cyerekezo kimwe. Umurambararo w'imigozi uri hagati ya mikoroni 0.5 na 10, kandi umurambararo w'imigozi ni hafi kimwe cya mirongo itatu cy'umusatsi.

Nkuko bigaragara ku ishusho, haracyari icyuho kinini muri iyo mask munsi ya mikorosikopi ya elegitoroniki. None se twakwirinda dute iyo virusi?

Udupfukamunwakurinda virusi ukora ibintu bibiri: gufata no gufata

Gufata:

Ibikoresho byo kuyungurura byishingikiriza ku myenda cyangwa inzira zitaboshye kugira ngo bigere ku bucucike bw'imigozi iri mu mwanya kandi bikore urusobe runaka rw'imyenge, bityo bigakora ingaruka "zo kuziba" ku mwuka utemba. Uduce duto turi mu kirere "dufatwa" no kugongana n'imigozi cyangwa no kubuza imigozi ku ruhande rw'ibikoresho byo kuyungurura. Ku duce tutari utw'ibinyabuzima turi mu kirere (nk'umukungugu, PM2.5, nibindi), ubushobozi bwo gusukura udupfukamunwa bushingiye ahanini ku bushobozi bwo gufata ibintu byo kuyungurura bumwe.

Kumenya:

Ku bijyanye na masks zo kurinda umubiri, bitewe n'ubunini buto cyane bw'udukoko nka virusi, biragoye gusukura ibintu byinshi byangiza binyuze mu gufata icyuho cy'udupfukamunwa. Kubwibyo, gukurura amashanyarazi byabaye ikintu cy'ingenzi mu kazi ko kurinda masks. Imigozi gakondo irakomeye cyane mu gukora no gutwara amashanyarazi adahindagurika, bityo masks ya gaze nta ngaruka zo gukurura amashanyarazi. Kandi fibre ya polymer isanzwe ni ibikoresho byiza cyane byo gukora no kubika amashanyarazi adahindagurika (iyi ngingo, ushobora kugereranya ibyiyumvo byo kwambara imyenda y'ipamba n'imyenda ya shimi), bigatuma "mu buryo busanzwe" igira imikorere myiza yo gukurura amashanyarazi. Abashakashatsi bakoze akazi kenshi ku buryo bwo gukora no kubungabunga imikorere y'ibikoresho bya filter. Mu gukora masks, hakoreshejwe uburyo bwa mekanike cyangwa ikoranabuhanga kugira ngo wongere ingufu z'amashanyarazi zidahindagurika mu bikoresho byashongeshejwe.

Bitewe n'ubushobozi bwihariye bwo kunyuzamo amazi hakoreshejwe amashanyarazi, ikoranabuhanga ryo gushonga rishobora gukora imigozi y'ibinyabutabire ifite umurambararo muto kurusha imigozi karemano, ibyo bikaba binafasha mu gukora imigozi y'ibinyabutabire. Nta gushidikanya ko umwenda udakozwe muri polypropylene udafite ubudodo ari wo wa mbere ukoreshwa mu bikoresho byo kurinda udupfukamunwa mu buvuzi.
