Iterambere ry'ikoranabuhanga rya melt-Jet nonwovens -- Ikoranabuhanga rya melt-jet rifite ibice bibiri
Kuva mu kinyejana cya 21, iterambere ry'ikoranabuhanga ryo gushonga nonwovens ku isi ryateye imbere ku buryo bukabije.
Ipfundo ry'umutako:
Ishobora gutuma ibitari ibyo kuboha byumvikana ko byoroshye, ishobora gukorwamo ibikoresho bito, bidasanzwe kandi bifite imiterere yihariye. Muri rusange, igice cy'imbere gikozwe mu bikoresho bihendutse, kandi polymer ihenze ifite imiterere yihariye cyangwa ikenewe ni igice cy'inyuma, nka core ya polypropylene n'igice cy'inyuma cya nylon kugira ngo fibre ibe hygroscopic. Igice cy'imbere ni polypropylene, kandi uruhu rw'inyuma rushobora gufatana na polyethylene ifite aho ishongesha cyangwa polypropylene yahinduwe, polyester yahinduwe, nibindi. Ku bijyanye na fibre iyobora umukara wa karuboni, igice cy'imbere gihambiraho.
Ubwoko bw'ingingo:
Ubusanzwe ibikoresho bidafunze bifite ubuziranenge bwiza bikozwe muri polimeri ebyiri zitandukanye cyangwa polimeri imwe ifite ubushyuhe butandukanye mu migozi ibiri ihuriranye. Uburyo butandukanye bwo gushyushya polimeri zitandukanye bushobora gukoreshwa mu gukora imigozi ipfunze neza. Urugero, ikigo cya 3M cyakoze ibikoresho bidafunze bya PET/PP bifite ubuziranenge buvanze n’ibice bibiri. Bitewe no gupfunyika gutandukanye, ibikoresho bidafunze bikora ubushyuhe buvanze n’ibice bibiri, bigatuma ibikoresho bidafunze bigira ubuziranenge bwiza.
Ubwoko bwa Terminal:
Ibi biri mu bwoko bw'amababi atatu, ubwoko bw'umurambararo n'ubwoko bw'imvange ubundi bwoko bwa polymer, nk'ubudahinduka, ubushyuhe, fibre iyobora amazi bishobora kuba hejuru ya polymer iyobora amazi, ntabwo bishobora gusa kuba biyobora amazi, biyobora amazi, birwanya ubushyuhe, kandi bikabika ingano ya polymer iyobora amazi.
Ubwoko bwa microdenier:
Ishusho y'agace k'umuhondo, igice cy'umurongo w'umurongo gishobora gukoreshwa, gishobora kandi kuba igice cy'ubwoko bw'ikirwa cyo mu nyanja. Gukoresha polimeri ebyiri zidahuye kugira ngo zikureho kugira ngo hakorwe urusobe rw'imigozi myiza cyane, cyangwa ndetse n'urusobe rwa nanofiber, nka fibre ya Kimberly-Clark yo mu bwoko bwa strip-type two-component, ni urusobe rw'imigozi myiza cyane rukoresha uburyo fibre ebyiri zikozwe muri polimeri ebyiri zidahuye zishobora gukurwaho burundu mu gihe kitarenze isegonda rimwe mu mazi ashyushye. Ubwoko bw'ikirwa cyo mu nyanja buzashongesha inyanja kugira ngo haboneke urusobe rwiza rw'imigozi yo mu kirwa.
Imvange:
Ni urusobe rw'imigozi rufite ibikoresho bitandukanye, amabara atandukanye, imigozi itandukanye, imiterere itandukanye y'ibice, ndetse n'imbere mu ruhu havanzemo imigozi yombi hamwe n'ibice bibiri, ku buryo imigozi igira imiterere yose ikenewe. Ubwo bwoko bwa melt-jet two-component fibre nonwoven cyangwa mixed fibre nonwoven bushobora kunoza imiterere y'iyungurura ry'icyuma gitunganya ugereranije n'ibicuruzwa rusange bya melt-jet, kandi bugatuma icyuma gitunganya utwuma gifite imiterere irwanya static, amashanyarazi atwara, imiterere ya hygroscopic, imiterere y'inzitizi, nibindi. Cyangwa bigatuma fibre mesh ihuza, fluffy, air permeability irushaho kuba nziza.
Fibre ya shotcrete ishongeshejwe ifite ibice bibiri ishobora kongera ubushobozi bwo gukora polimeri imwe, nka polypropylene irahendutse cyane, ariko ku bikoresho by'ubuvuzi, ntabwo irwanya imirasire, bityo ishobora kuba polypropylene nk'ishingiro, mu gice cyayo cyo hanze guhitamo polimeri ikwiye irwanya imirasire ipfunyitse hanze bishobora gukemura ikibazo cyo kudahangana n'imirasire. Bityo, ibicuruzwa bishobora kuba bihendutse kandi byujuje ibisabwa, nk'ibikoresho bihindura ubushyuhe n'ubushuhe mu buryo bw'ubuhumekero mu rwego rw'ubuvuzi, bishobora gutanga ubushyuhe n'ubushuhe bisanzwe bikwiye. Ifite uburemere bworoshye, ishobora gukoreshwa cyangwa yoroshye kuyikuraho, ihendutse, ariko kandi ishobora no kugira uruhare rw'inyongera mu gukuraho akayunguruzo k'imyanda. Ishobora kuba igizwe n'urusobe rw'imirasire ivanze n'ibice bibiri bingana.
Fibre y’uruhu ifite ibice bibiri irakoreshwa, igice cy’imbere ni polypropylene naho igice cy’imbere ni nayiloni. Fibre y’ibice bibiri ishobora kandi gushyirwaho igice cyihariye, nk’imiterere y’amababi atatu cyangwa imiterere y’amababi menshi, kugira ngo ubuso bwayo bube bunini. Hagati aho, polymer zishobora kunoza imikorere yo kuyungurura zishobora no gukoreshwa mu gice cy’ubuso cyangwa ku mpande z’imigozi. Meshi ya alkene cyangwa polyester fusible fibre ifite ibice bibiri ishobora gukorwamo filter y’amazi n’umwuka. Fibre ishongesha ishobora no gukoreshwa mu filter y’itabi; Ingaruka zo gukurura wino zikoreshwa mu gukora core yo gukurura wino yo mu rwego rwo hejuru. Inkoni yo gukurura amazi yo mu gice cy’imbere ikoreshwa mu kubika no gukwirakwiza amazi, nibindi.
Iterambere ry'ikoranabuhanga rya melt blown nonwovens -- Melt blown nanofibers
Kugira ngo hakorwe nanofibers, imyobo ya spinneret ni mito cyane ugereranyije n’iboneka mu bikoresho bisanzwe byo gutera inshinge. NTI ishobora kuba ntoya nka 0.0635 mm (ni ukuvuga mikoroni 63.5) cyangwa ntoya nka 0.0025 ft. Udupande twa spinneret two mu buryo bwa modular dushobora guhuzwa kugeza ku bugari bwa metero zirenga 3. Ubugari bwa fibre ishongeshejwe ni nanometer 500. Udupira twinshi cyane dushobora kuba nanometer 200 z’umurambararo.
Kubera ko ibikoresho byo gushonga no gutera imiti yo mu bwoko bwa nanofibers bifite imyobo mito yo mu bwoko bwa orifical, niba nta ngamba zafashwe, umusaruro uzagabanuka cyane. Kubwibyo, NTI ikoresha uburyo bwo kongera umubare w'imyobo yo mu bwoko bwa orifical, kandi buri sahani ya spinneret ifite imirongo 3 cyangwa irenga y'imyobo yo mu bwoko bwa orifical. Mu guhuza ibice byinshi by'ibice (bitewe n'ubugari), umusaruro mu gihe cyo kuzunguruka ushobora kwiyongera cyane. Uko ibintu bimeze ni uko iyo hakoreshejwe imyobo ya mikoroni 63.5, umubare w'imyobo mu murongo umwe wa spinnerets kuri metero ni 2880. Iyo hakoreshejwe imirongo itatu, umubare w'imyobo mu murongo umwe wa spinnerets kuri metero ushobora kugera kuri 8640, ku buryo umusaruro ushobora kugereranywa n'uwo kuzunguruka fibre isanzwe ya shotcrete.
Kubera ko spinnerets ntoya zifite imyobo myinshi ihenze kandi zishobora kwangirika (gucikagurika munsi y’umuvuduko mwinshi), amasosiyete yashyizeho uburyo bushya bwo guhuza kugira ngo yongere umuvuduko wa spinnerets no gukumira amazi asohoka mugihe cy’umuvuduko mwinshi.
Fibre ivanze nanometero ishobora gukoreshwa nk'uburyo bwo kuyungurura, bishobora kunoza cyane imikorere yo kuyungurura. Hari kandi amakuru agaragaza ko kubera ko fibre iri mu bikoresho bidafite ubudodo bya nanometero bivanze n'ibitari byo, imyenda ya melt-jet ishobora guhuzwa n'imyenda ifite uburemere bwa garama buke, ishobora kwihanganira umuvuduko umwe w'amazi, kandi ibicuruzwa bya SMS bikozwe muri yo bishobora kugabanya igipimo cya fibre ya melt-jet.
Turiigitambaro kidafunze gikozwe mu buryo bwa meltblown cyo gupfuka mu masouruganda, murakaza neza kutugisha inama ~
