Gushonga byashushanyijeho imyenda idoda hamwe nibiranga

Inzira yo gushonga yahujije imyenda idoda

Inzira yo gushonga yahuha imyenda idoda: kugaburira polymer - gushonga gushonga - gukora fibre - gukonjesha fibre - gushiraho urubuga - gushimangira imyenda.

Ibice bibiri bishonga tekinoroji

Kuva mu ntangiriro z'ikinyejana cya 21, iterambere ry'ikoranabuhanga ryashongeshejwe ryateye imbere byihuse ku rwego mpuzamahanga.

Isosiyete ya Hills na Nordson muri Reta zunzubumwe zamerika yateje imbere ikoranabuhanga ryibice bibiri bishonga mbere, harimo uruhu rwuruhu, rubangikanye, inyabutatu nubundi bwoko. Ubusanzwe fibre yegeranye na 2 µ, kandi umubare wibyobo mubice byashongeshejwe birashobora gushika kumyobo 100 kuri santimetero imwe, hamwe nogusohora 0.5g / min kuri buri mwobo.

Ubwoko bw'uruhu:

Irashobora gutuma imyenda idoda ikozwe neza kandi irashobora gukorwa mubicuruzwa byibanda cyane, bidasanzwe, kandi bidasanzwe. Mubisanzwe, ibikoresho bihenze bikoreshwa nkibyingenzi, mugihe polymers zihenze zifite ibintu byihariye cyangwa bisabwa zikoreshwa nkurwego rwo hanze, nka polypropilene yibanze hamwe na nylon kumurongo winyuma, bigatuma fibre hygroscopique; Intangiriro ikozwe muri polypropilene, naho igice cyo hanze gikozwe mumashanyarazi make ya polyethylene cyangwa yahinduwe na polypropilene, polyester yahinduwe, nibindi bishobora gukoreshwa muguhuza. Kuri karuboni yumukara utwara fibre, intandaro yo kuyobora ipfunyitse imbere.

Ubwoko bubangikanye:

Irashobora gukora imyenda idoda idoze ifite elastique nziza, mubisanzwe ikozwe muri polymers ebyiri zitandukanye cyangwa polymer imwe hamwe na viscosité zitandukanye kugirango ibangikanye fibre yibice bibiri. Mugukoresha ibintu bitandukanye bigabanya ubushyuhe bwa polymers zitandukanye, fibre zigoramye zirashobora gukorwa. Kurugero, Isosiyete 3M yateje imbere imyenda idoda ikozwe mumashanyarazi ya PET / PP yibice bibiri bigize fibre, ibyo, kubera kugabanuka gutandukanye, gukora impinduramatwara kandi bigatanga umwenda utaboshywe neza cyane.

Ubwoko bwa Terminal:

Ubu ni ubundi bwoko bwa polymer ikomatanya ikoreshwa mubibabi bitatu, umusaraba, na terminal. Mugihe ukora fibre anti-static, itwara amazi, hamwe nuyobora, polymers ikora irashobora kuba hejuru hejuru, idashobora gutwara gusa ubushuhe, ariko kandi ikora amashanyarazi, anti-static, kandi ikabika umubare wa polymer ukoresha.

Ubwoko bwa Micro Dan:

Amababi ya orange afite ishusho, ibice bisa nkibishishwa, cyangwa ibice byizinga birashobora gukoreshwa. Gukoresha polymers ebyiri zidahuye kugirango ushishimure kandi ukore ultrafine fibre web, ndetse na nanofiber web. Kurugero, Kimberly Clark yateje ubwoko bwa fibre yibice bibiri, ikoresha ibiranga fibre yibice bibiri bikozwe muri polymers ebyiri zidahuye zishobora gukurwaho burundu mugihe kitarenze isegonda mumazi ashyushye kugirango ikore imiyoboro ya fibre ultrafine. Kubwoko bwizinga, inyanja igomba gushonga kugirango ibone umuyoboro mwiza wa fibre.

Ubwoko bwa Hybrid:

Ni urubuga rwa fibre rukozwe no kuvanga ibikoresho bitandukanye, amabara, fibre, imiterere ihuza ibice, ndetse na fibre ihwanye nuruhu rwuruhu, hamwe na co spun hamwe nibice bibiri bigize fibre, kugirango fibre ibintu bisabwa. Ugereranije nibisanzwe bya fibre fibre yibicuruzwa, ubu bwoko bwa melt bwatwikiriye ibice bibiri bya fibre idahwitse cyangwa imyenda ivanze ya fibre idahwitse irashobora kurushaho kunoza imikorere yo kuyungurura uburyo bwo kuyungurura, kandi bigatuma uburyo bwo kuyungurura bugira anti-static, itwara, ikurura amazi, kandi byongera imbaraga za barrière; Cyangwa utezimbere gufatana, guhindagurika, no guhumeka kurubuga rwa fibre.

Ibice bibiri bigize fibre fibre irashobora kuzuza ibitagenda neza kumiterere ya polymer imwe. Kurugero, polypropilene isa naho ihendutse, ariko iyo ikoreshejwe mubikoresho byubuvuzi nubuzima, ntabwo irwanya imishwarara. Kubwibyo, polypropilene irashobora gukoreshwa nkibyingenzi, kandi polymer ikwiye irwanya imishwarara irashobora gutoranywa kumurongo winyuma kugirango uyizenguruke, bityo bikemure ikibazo cyo kurwanya imirasire. Ibi birashobora gutuma ibicuruzwa bidahenze mugihe byujuje ibyangombwa bisabwa, nkubushyuhe nubushyuhe bukoreshwa muri sisitemu yubuhumekero mubuvuzi, bushobora gutanga ubushyuhe nubushuhe bukwiye. Nibyoroshye, birashobora gukoreshwa cyangwa byoroshye kwanduza, bihendutse, kandi birashobora no kuba akayunguruzo kiyongera mugukuraho umwanda. Irashobora kuba igizwe na bibiri bingana bivanze bibiri-bigizwe na fibre fibre web. Kwemeza uruhu rwibanze rwubwoko bubiri bwibice, intangiriro ikozwe muri polypropilene naho uruhu rugizwe na nylon. Ibice bibiri bigize fibre birashobora kandi gufata ibice bidasanzwe, nka trilobite na multilobes, kugirango byongere ubuso bwabo. Mugihe kimwe, polymers zishobora kunoza imikorere yo kuyungurura zirashobora gukoreshwa hejuru yazo cyangwa kumutwe. Ibice bibiri bigize fibre mesh ya olefin cyangwa polyester yashonga uburyo bwakoreshejwe burashobora gukorwa mumazi ya silindrike na gaz. Gushonga byashizwemo ibice bibiri bya fibre mesh birashobora kandi gukoreshwa muburyo bwo kuyungurura itabi; Gukoresha ingirakamaro yo guswera kugirango ukore wino-yohejuru ikurura ingirangingo; Inkoni yibanze yo kubika amazi no gushiramo.

Gutezimbere gushonga bya tekinoroji idahwitse - gushonga nanofibers

Mu bihe byashize, iterambere rya fibre ya meltblown yari ishingiye ku ikoranabuhanga ryemewe na Exxon, ariko mu myaka yashize, amasosiyete mpuzamahanga menshi yacishije mu ikoranabuhanga rya Exxon kugira ngo akore fibre nziza ya nanoscale.

Isosiyete ya Hills yakoze ubushakashatsi bwimbitse kuri fibre ya nano meltblown kandi bivugwa ko igeze ku ntera yinganda. Andi masosiyete nka Non Woven Technologies (NTI) nayo yateje imbere uburyo n'ikoranabuhanga byo gukora fibre nano meltblown kandi yabonye patenti.

Kugirango uzunguruke nanofibers, imyobo ya nozzle ni nziza cyane kuruta iyo ku bikoresho bisanzwe byashongeshejwe. NTI irashobora gukoresha nozzles ntoya nka milimetero 0,0635 (microne 63.5) cyangwa santimetero 0.0025, kandi imiterere ya modular ya spinneret irashobora guhuzwa kugirango ikore ubugari bwa metero zirenga 3. Diameter ya fibre yashonze izunguruka muri ubu buryo ni nanometero 500. Diameter yoroheje cyane ya fibre irashobora kugera kuri nanometero 200.

Ibikoresho byashongeshejwe byo kuzunguruka nanofibre bifite utwobo duto twa spray, kandi niba nta ngamba zafashwe, byanze bikunze umusaruro uzagabanuka cyane. Kubwibyo, NTI yongereye umubare wibyobo bya spray, hamwe na plaque ya spray ifite imirongo 3 cyangwa irenga imirongo ya spray. Guhuza ibice byinshi bigize ibice (bitewe n'ubugari) hamwe birashobora kongera umusaruro mugihe cyo kuzunguruka. Imiterere nyayo nuko iyo ukoresheje imyobo ya micron 63.5, umubare wibyobo kuri metero imwe yumurongo umwe uzunguruka ni 280. Niba hakoreshejwe imirongo itatu, umubare wibyobo kuri metero ya spinneret urashobora kugera kuri 8640, ibyo bikaba bihwanye no gukora fibre zisanzwe zishonga.

Bitewe nigiciro cyinshi kandi cyoroshye kumeneka (gucika munsi yumuvuduko mwinshi) wa spinerets yoroheje ifite umwobo mwinshi cyane, ibigo bitandukanye byateje imbere uburyo bushya bwo guhuza imiyoboro kugirango byongere igihe kirekire kandi birinde kumeneka kumuvuduko mwinshi.

Kugeza ubu, fibre ya nano meltblown irashobora gukoreshwa nkibitangazamakuru byo kuyungurura, bishobora kunoza imikorere ya filteri. Hariho kandi amakuru yerekana ko kubera fibre nziza muri nanoscale meltblown imyenda idoda, imyenda yoroshye kandi iremereye ya meltblown irashobora gukoreshwa hamwe na spunbond, ishobora gukomeza kwihanganira umuvuduko umwe wamazi. Ibicuruzwa bya SMS bikozwe muri byo birashobora kugabanya igipimo cya fibre fibre.

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.
