Igitambaro cya Meltblown ni iki | JINHAOCHENG

Igitambaro gishonga ni iki?igitambaro kidapfutse gishongeshejweUmuhanga Jin Haocheng kugira ngo abagezeho, ibikubiye muri iyi nyandiko ni ibi bikurikira:

Igitambaro gikozwe muri polypropylene gishongeshejwe gifite umurambararo wa fibre wa mikoroni 1 kugeza kuri 5. Imboga nyinshi, imiterere yoroshye, ubushobozi bwo kuzingira neza. Iyi miterere yihariye ya microfiber ituma umubare wa fibre kuri buri gice cy'ubuso n'ubuso bwihariye byiyongera.

Kugira ngo igitambaro gishongeshejwe kigire ubushobozi bwo kuyungurura neza, kurinda, gukingira ubushyuhe no kwinjiza amavuta. Kibereye ibikoresho byo kuyungurura umwuka n'amazi, ibikoresho byo gukingira ubushyuhe, ibikoresho byo kuyungurura, ibikoresho byo gupfuka mu maso, ibikoresho byo kubika ubushyuhe, ibikoresho byo gupfuka amavuta, ibyo guhanagura n'ibindi bikoresho.

Uburyo bwo gukoresha umwenda ushongeshejwe

Imyenda yo kwa muganga n'iy'ubuzima: ikanzu yo kubaga, imyenda yo kwirinda, umwenda wo gupfunyikamo imiti yica udukoko, udupfukamunwa, imyenda yo kwambaraho imyenda, udutambaro tw'abagore two mu rugo, n'ibindi.

Igitambaro cyo gushariza mu rugo: igitambaro cyo ku rukuta, igitambaro cyo ku meza, igitanda, igitambaro cyo kuryamaho, nibindi;

Imyenda yo kwambara: umwenda, umwenda ufatana, ipamba ikoze mu ipamba, ubwoko bwose bw'uruhu rw'ubukorano, nibindi.

Imyenda yo mu nganda: ibikoresho byo kuyungurura, ibikoresho bikingira ubushyuhe, umufuka wo gupakira sima, igitambaro cya geotextile, umwenda upfutse, nibindi.

Igitambaro cy'ubuhinzi: igitambaro cyo kurinda imyaka, igitambaro cy'imbuto, igitambaro cyo kuhira, umwenda wo gukingira, n'ibindi. 

Ibindi: ipamba ry'ahantu, ibikoresho bikingira ubushyuhe, agakoresho ko gukurura amavuta, akayunguruzo k'umwotsi, agapfunyika k'icyayi, n'ibindi.

Ni irihe tandukaniro riri hagati y'igitambaro gishongeshejwe n'igitambaro kidaboshye?

Igitambaro gishongeshejwe gikozwe ahanini muri polypropylene ifite umurambararo wa fibre ugera kuri mikoroni 1-5. Iyi mashini ifite uburyo butandukanye bwo kurenga, imiterere yoroshye, kandi irwanya guhindagurika. Microfiber ifite imiterere yihariye y'imiyoboro y'amaraso, yongera umubare w'imiyoboro kuri buri gice cy'ubuso n'ubuso bwihariye.

Ibikoresho byo kuyungurura ni microfibers za polypropylene zishongeshejwe zikwirakwira mu buryo butunguranye, zisa neza, ziroroshye, ingano ya fibre yoroshye ya 0.5-1.0, ikwirakwira ridasanzwe rya fibre ritanga amahirwe menshi yo guhuza ubushyuhe.

Igitambaro cyashongeshejwe gifite ubushobozi bwiza bwo kuyungurura, gukingira, gukingira no kwinjiza amavuta. Gishobora gukoreshwa nk'ibikoresho byo kuyungurura umwuka n'amazi, ibikoresho byo kwitandukanya, ibikoresho byo kwinjiza, ibikoresho byo gupfuka, ibikoresho byo kubika ubushyuhe, ibikoresho byo kwinjiza amavuta n'igitambaro cyo guhanagura.

Bityo rero, ibikoresho byo kuyungurura imyuka bishongeshejwe bifite ubuso bunini bwihariye n'imyenge myinshi (≥75%). Mu gihe cyo kuyungurura umuvuduko mwinshi cyane, ibicuruzwa bifite ubushobozi buke bwo kudakora neza, ubushobozi bwo gukora neza, ubushobozi bwo gutwika ivumbi ryinshi n'ibindi.

Imyenda idafunze ntishobora guhumeka, ihumeka, yoroshye, yoroheje, ntishobora gushya, yoroshye kubora, ntigira uburozi, ntitera imbaraga, ifite amabara menshi, ihendutse, ishobora kongera gukoreshwa n'ibindi. Ubu buvumbuzi bufata ibice bya polypropylene (PP) nk'ibikoresho fatizo, kandi buhora bukorwa binyuze mu gushonga kw'ubushyuhe bwinshi, gutera, gupakira no gushyushya.

Ibiranga umwenda utari uwo kuboha:

Igitambaro kidafunze nta budodo kigira, biroroshye cyane kugikata no kudoda, gifite uburemere bworoshye, gifite imiterere yoroshye, nk'abakunda ubukorikori.

Kubera ko ari umwenda ushobora gukorwa udakoze ku ruziga, ukeneye gusa gusesengura no kwerekeza cyangwa gutunganya mu buryo butunguranye umugozi mugufi cyangwa umugozi w'umwenda kugira ngo ukore imiterere y'urushundura rw'imigozi, hanyuma ugakoresha uburyo bwa gakondo bwo kuwukomeza mu buryo bwa mekanike, ubushyuhe cyangwa uburyo bwa chimique.

Ibi ntibikorwa no kuboha ubudodo, ahubwo bikorwa no guhuza imigozi neza, ku buryo iyo ubonye izina ry'uburyo bufatana ku mwenda, uzasanga udashobora gukururwa mu mwenda. Imyenda idafunze yanyuze mu ihame rya gakondo ry'imyenda, ifite inzira ngufi, umuvuduko wihuse wo gukora, umusaruro mwinshi, ikiguzi gito, ikoreshwa cyane, ibikoresho fatizo n'ibindi.

Isano iri hagati y'imyenda idafunze n'imyenda ipfundikiye:

Imitako idafunze ifite imigozi n'ibindi bikoresho byayo. Urukurikirane rw'ibikorwa byo gukora imitako idafunze bigaragazwa n'imitako idafunze ifite imigozi, imitako idafunze neza, imitako idafunze neza n'imitako idafunze neza. Ibiranga ni ibi bikurikira: imitako idafunze ni uburyo bwo gukora, kandi abanyeshuri benshi ku isoko bakoresha imitako idafunze neza kugira ngo bakore imitako idafunze neza.

Igitambaro kidaboshye bitewe n'imiterere y'ibice bitandukanye, polyester, polypropylene, nylon, polyurethane, aside acrylic n'ibindi. Ibice bitandukanye bifite imiterere itandukanye rwose y'igitambaro kidaboshye. Igitambaro kidaboshye akenshi kivuga ku bifunga bya polyester n'ibifunga bya polypropylene. Imiterere y'igitambaro cyombi isa cyane kandi ishobora kumenyekana bitewe n'ubushyuhe bwinshi.

Umutambara udafunze bivuga umwenda wa nyuma udafunze ukozwe hakoreshejwe urupapuro rwa polymer, agace gato k'umugozi cyangwa umugozi ushyiramo umwuka cyangwa gutunganya imashini, ukozwe mu migozi, ukozwe mu migozi cyangwa ukozwe mu buryo bushyushye.

Ibikoresho bishya byoroshye kandi bihumeka kandi bifite imiterere irambuye, ntibitanga ubudodo, bikomeye, biramba, byoroshye, bisa n'ubudodo, bifite ibikoresho byiza, ariko ipamba nayo ifite imiterere, ugereranyije n'amasakoshi adaboshye yoroshye gukora, kandi ihendutse.

Ibyiza:

Uburemere bworoheje: polypropylene synthetic resin nk'ikintu cy'ingenzi kigize umusaruro w'ibikoresho fatizo, uburemere bwihariye bwa 0.9 gusa, bitatu bya gatanu by'ipamba ryo mu Bushinwa gusa, rifite ubwiza n'isura nziza.

Ikozwe mu buryo bworoshye bwo gushonga (2-3D) bushyushye butuma ikora...Igicuruzwa cyarangiye gifite ubworoherane buri hagati kandi gitanga ihumure.

Ishobora guhumeka amazi: imashini ya polypropylene idafata amazi, nta bushyuhe ifite, uruhande rw'amazi rwarangiye, rufite imyenge, umwuka mwiza wo kwinjira, igitambaro cyumye cyoroshye kugifata neza. Ubwoko 100 bwa fibre, byoroshye kumesa.

Ntirigira uburozi, ntirigira umujinya: umusaruro ushobora kuba uhuye neza n'ibikoresho fatizo bya FDA byo mu rwego rwo hejuru byo gukora, nturimo ibindi bikoresho bya shimi byiganjemo abanyeshuri, imikorere irahamye, ntabwo rigira uburozi, nta mpumuro, nta burakari ku ruhu.

Irwanya mikorobe n'ibinyabutabire: polypropylene ni ikintu kidakora neza, ntabwo ari ibintu bitera imyuka mibi, gishobora gutandukanya bagiteri n'udukoko mu mazi; Irwanya bagiteri, ingese ya alkali, ibikoresho byarangiye ntibigira ingaruka ku mbaraga z'isuri.

Imiterere y’imiti irwanya udukoko: gukurura hakoreshejwe amazi, imyumbati, bagiteri n’udukoko kandi amazi ashobora gukuraho isuri n’ibore ry’ibikomoka kuri iyo miti.

Imiterere myiza y’umubiri: ikozwe muri polypropylene ishobora gukwirakwizwa mu buryo butaziguye mu rusobe rw’ubushyuhe, umusaruro ufite imbaraga ziruta iz’ibicuruzwa rusange bya fibre, imbaraga nta cyerekezo zigira, imbaraga z’imiterere zihagaze n’izitambitse n’ibindi bisa nabyo.

Ku bijyanye no kurengera ibidukikije: imyenda myinshi idafunze ikozwe muri polypropylene, mu gihe imifuka ya pulasitiki ikozwe muri polyethylene. Nubwo amazina yayo asa, ibi bintu byombi bifite imiterere itandukanye cyane ya shimi. Imiterere ya shimi ya polypropylene irahamye cyane kandi iragoye gusenya, bityo bifata imyaka 300 kugira ngo imifuka ya pulasitiki isenye. Kandi imiterere ya shimi ya polypropylene ntabwo ikomeye, urunigi rwa molekile rworoshye gusenya, bityo ni ngombwa ko ikorwa neza. Imifuka idafunze ikomeza ku nshuro ikurikira mu buryo butari uburozi kandi ishobora kubora burundu mu minsi 90. Byongeye kandi, imifuka yo guhaha idafunze ishobora kongera gukoreshwa inshuro zirenga 10, kandi umwanda ku bidukikije nyuma y'imyanda ni 10% gusa by'imifuka ya pulasitiki.

Ibibi:

Ingufu nke kandi ntiziramba ugereranije n'imyenda iboshywe.

Ntibishobora gusukurwa nk'ibindi bitambaro.

Kubera ko insinga zitondetse mu cyerekezo runaka, biroroshye kuzicamo uturutse ku nguni y'iburyo, nibindi. Kubwibyo, intego yo kunoza uburyo bwo gukora ni ukunoza ubushobozi bwo kwirinda gucikamo ibice.

Iyi nkuru iri hejuru yateguwe kandi igasohorwa n'abacuruzi b'inganda zidafite ubudodo buboshye. Niba utabyumva, murakaza neza kutugisha inama!
