Imitako idafunze neza ya fibre
Uburyo bwo gushonga bushongeshwa kandi ni bumwe mu buryo bwa polymer bushyirwa mu buryo butaziguye mu icupa ry’urushundura, ni ugusohora icyuma gishongeshwa na polimeri binyuze mu guhumeka k’umwuka mu bushyuhe bwinshi cyangwa ubundi buryo bwo gushonga butuma habaho umuvuduko ukabije no gukora fibre nziza cyane, hanyuma bigateranywa mu icupa ry’urushundura cyangwa umwenda w’urushundura wakozwe ku rusobe rw’imigozi, amaherezo bigatuma ingaruka zo gufatana zikomera kuko fibre ishongeshwa idafite ubudodo.
Ihame ryo gukora fibre ya fusion-jet
1. Ibisa n'ibitandukanye n'uburyo bwa spunbonded
Uburyo bwo guhuza imigozi
Bizwi kandi nk'uburyo bwo kuzunguruka mu buryo butaziguye mu mwenda, ni ugukoresha uburyo bwo kuzunguruka nk'igice cya polymer mu gushonga no gushyiraho uburyo bwo kuzunguruka bukomeza ku muyoboro, hanyuma no guhuza, kurangiza n'ibindi bikorwa byakozwe.
Ikintu gisanzwe
Polima igomba gukurwamo n'umwobo wa spinneret mu gihe cyo gushonga
(2) urusobe rw'imigozi rushobora kuba uguhuza ubushyuhe (guhuza ubuso cyangwa guhuza ingingo) cyangwa guhuza ubwarwo mu gushimangira imyenda idafunze
B itandukaniro
Mu buryo bwa spunbond: umwuka ukonje utunguranye urakonjeshwa, icyarimwe, urambura, ugakora umugozi uhoraho, ugakwirakwira mu mwenda w'urushundura
Uburyo bwo gushonga: gushonga umwuka ushyushye cyane, hakoreshejwe uburyo bwo kurambura cyane, gukora fibre ngufi, ku muvuduko mwinshi cyane kugira ngo iguruke mu mwenda cyangwa gufunga umugozi w'umuyoboro kugira ngo habeho urusobe rw'imiyoboro.
(2) uburyo bwa spunbond: uburyo bwo gukomeza urusobe rw'imiyoboro ya fibre, hiyongereyeho uburyo bwo guhuza bushyushye, ariko nanone gufata acupuncture, amazi, guhuza imiti n'ubundi buryo.
Uburyo bwo gushonga: ahanini bushingiye ku guhuza ubushyuhe cyangwa kwihuza
2. Uburyo gakondo bw'ikoranabuhanga
Gutanga polymer → gushonga → gukonjesha fibre → gukonjesha fibre → gushushanya mesh → guhuza (mesh ihamye) → gucura inkombe → kurangiza nyuma yo kurangiza cyangwa kurangiza byihariye
Ibiryo bya polymer - polymer muri rusange ikorwamo uduce duto tw’uruziga, duto, tugasukwa mu ndobo cyangwa mu gikoni, hanyuma tugashyirwa mu cyuma gisohora ibyuma
Gushonga -- ku mpera y’icyuma gisohora ibyuma, agace ka polymer kagomba kuvangwa n’icyuma gikomeza gushonga, igikoresho cyo kwera n’ibindi bikoresho by’ibanze, masterbatch y’amabara n’ibindi bikoresho fatizo bikenewe, nyuma yo kuvanga neza mu cyuma gisohora ibyuma, bigashyushya bigashonga, hanyuma icyo cyuma gishonga kikazashyirwa mu cyuma gipima amazi binyuze mu cyuma gipima amazi binyuze mu cyuma gipima amazi. Mu gihe cyo gushonga no gutera, icyuma gisohora amazi rusange kinagabanya uburemere bwa molekile ya polymer binyuze mu gikorwa cyacyo cyo gukata no kwangirika k’ubushyuhe.
Imiterere ya fibre - imyuka iyunguruye inyura muri sisitemu yo gukwirakwiza hanyuma igashyirwa kuri buri tsinda rya spinnerets kugira ngo habeho ingano imwe yo gusohora kuri buri spinneret. Imyuka iyunguruye ya fibre iterwa na fusion itandukanye n'ubundi buryo bwo kuzunguruka, imyobo ya spinneret igomba gutondekwa mu murongo ugororotse, impande zo hejuru n'izo hepfo zifite imyobo y'amazi.
Gukonjesha fibre - umwuka mwinshi w'ubushyuhe bw'icyumba unyuzwa mu mpande zombi za spinneret hanyuma ukavangwa n'umugezi w'umwuka ushyushye urimo fibre kugira ngo ukonje. Fibre yashongeshejwe irakonjesha kandi igakomeza gukomera.
Gutera umuyoboro - mu gukora udupira tudakozwe mu buryo bwa fibre, udupira dushobora gushyirwa mu buryo butambitse cyangwa buhagaze. Iyo dushyizwe mu buryo butambitse, udupira duto dushyirwa ku ngoma ikusanya uruziga kugira ngo dukore umuyoboro. Iyo dushyizwe mu buryo buhagaze, udupira tugwa ku gitambaro kigenda gitambagirana kugira ngo dukore umuyoboro.
Kole (umuyoboro uhamye) - uburyo bwo kwibohera buvuzwe haruguru, mu mpamvu zimwe na zimwe, igitambaro cyo gushonga kirahagije, nko: ibisabwa ku muyoboro wa fibre bifite imiterere yoroshye, ubushobozi bwo kubika umwuka cyangwa ubusa. Kandi mu bindi bikorwa byinshi, kwibohera gusa ntabwo bihagije, haracyakenewe kole ishyushye, kole ikozwe muri ultrasound cyangwa ubundi buryo bwo kuyibohera. Kole ishyushye
3. Imiterere y'imikorere y'udupira tudakozwe mu buryo bwa "melt-jet fibre nonwovens"
(1) inzira ngufi, umusaruro mwiza cyane;
Fibre ni nziza cyane, ingano y'imiyoboro ya fibre ni nziza, yoroshye, mu kuyungurura, irwanya udukoko, inyunganiramirire ifite ibyiza bidasanzwe;
Icyerekezo cya fibre ni gito, imbaraga z'urusobe rwa fibre ni nkeya;
Ibi bizatwara ingufu nyinshi.
Ibipimo by'ingenzi by'uburyo bwo gukora imashini ishongesha
1. Igipimo cy'ingufu zishonga (MFI)
Imbaraga n'uburebure bw'imyenda yasizweho fusion byaragabanutse uko MFI yiyongeraga. Kubwibyo, MFI y'ibikoresho fatizo isabwa kuba hejuru cyane kugira ngo amazi ashonge neza arusheho kuzamuka neza mu gihe cyo gushyuha kwa gaze.
2. Umuvuduko w'amazi ashyushye
Mu gihe cy'ubushyuhe bumwe, umuvuduko wa screw, intera yo kwakira n'ibindi bintu:
Umuvuduko w'umwuka ushyushye ↑ → umurambararo wa fibre ↓ → Utudomo tw'inyuma twumva kuva ku gukomera kugeza ku koroshye, udupira twinshi turiyongera, urusobe rw'inyuma rw'inyuma ruriyongera, rworoshye, imbaraga zariyongereye
Ariko umuvuduko w'umwuka ni munini cyane, byoroshye kugaragara nk'indabyo ziguruka, bigira ingaruka zikomeye ku isura y'umwenda
3. Inguni yo gutera umwuka ushyushye
Bigira ingaruka cyane cyane ku mikorere y'imitsi n'imiterere y'imitsi
Ibiranga n'imikoreshereze ya fibre ya melt-jet (imyenda idafunze)
1. Ibikoresho byo kuyungurura
IKORESHA cyane cyane imiterere yayo ya fibre nziza cyane, ikaba ari yo ikoreshwa bwa mbere kandi nini kurusha izindi. Gukenera ibikoresho bishya byo kuyungurura ni nabyo bituma habaho iterambere ry’udupira tudashonga.
Nta bwoya bugufi bw'ibikoresho biyungurura bugwa muri gazi cyangwa amazi yasukuwe nyuma yo kuyungurura hakoreshejwe igitambaro gishongesha.
Kugeza ubu, toni zirenga 20.000 z'ibikoresho bya melt-jet bikoreshwa ku isi buri mwaka, 65% muri byo bikoreshwa mu kuyungurura amazi, nko: kuyungurura ibinyobwa n'ibiribwa, kuyungurura amazi, kuyungurura ibyuma by'agaciro, irangi n'ibindi bicuruzwa bya shimi; 35% bikoreshwa mu kuyungurura gazi, nko: kuyungurura umwuka ushyushye mu nzu, kuyungurura umwuka n'amazi, kuyungurura icyumba cyo gusukura.
2. Ibikoresho by'ubuvuzi
Kugeza ubu, ni cyo gice cya kabiri kinini cy’imyenda ikoreshwa mu gushonga.
Muri aka gace, igipimo kinini ni igitambaro cyo kubaga, amarido yo mu cyumba cyo kubaga n'igitambaro cyo kwisiga, hamwe n'igitambaro gito cyo kwambara, kaseti, n'agapira ko kugabanya ububabare.
3. Ibikoresho by'isuku
(1) mu dutambaro tw'isuku
★ Igitambaro cyo gushonga gishyirwa mu gice cyo hasi cy'igitambaro cy'amazi gisukuye, urwego rwo kohereza imiyoboro y'amaraso
★ ikoreshwa ry'igitambaro cyo gushonga nk'inzitizi ku gice cy'uruzitiro cy'amazi, hamwe n'ibice bibiri by'igitambaro cyo gushonga aho gukoresha firime ya polyethylene idashobora kwinjiramo
(2) ku bijyanye n'amajipo y'abantu bakuru
Mu gihe cyo gukora, imigozi migufi y'umunyu ngugu w'ibiti ivangwa mu ruhererekane rw'imigozi ya fusiform kugira ngo hakorwe umwenda wihariye wa fusiform kandi ufata neza.
4. Ibikoresho bikurura amavuta
Nk'ibikoresho bikurura amavuta, ubushobozi bwo kuyungurura amavuta bushobora kugera ku nshuro 17 z'uburemere bwayo.
Muri rusange, igitambaro gishyirwa mu muyoboro muremure w’urushundura gikozwe mu muyoboro wa PET nk'urushundura rw'amazi rureremba kugira ngo amavuta ashobore kugabanuka no kwinjiza amavuta mu nyanja. Gishobora kandi gushyirwa mu mutwe w'igitambaro gikurura amavuta mu nyanja gikozwe mu gikoresho cyo gukusanya amavuta gikozwe mu gitambaro gishonga cya PP, gikomeza gusukurwa hejuru.
5. Ibikoresho by'imyenda
(1) ibikoresho bishyushye
Uburyo bwiza cyane bwo gukoresha ni igitambaro cyihariye cyakozwe n’ikigo cya 3M muri Leta Zunze Ubumwe za Amerika: mu gihe cyo gukoresha fibre ya PET, fibre ya PET ivangwa kugira ngo habeho imiterere y’umwuka igizwe na fibre ya PET ifite ubushobozi bwo guhindagurika neza na fibre ya PP ultrafine.
(2) imyenda y'abakozi ikoreshwa mu gihe cyo kuyikoresha
Uburyo bw'ibanze bwo gukoresha umwenda wa SMS, uretse ikoti ryo gukoresha, bwakoreshejwe neza mu nganda zikoresha imyenda yo kwirinda.
6, igitambaro gisukuye
Ahanini ni ugukoresha amavuta karemano ya PP, ubwoko butandukanye bw'amavuta akoreshwa mu kwanduza ibidukikije.
Bitewe n’iterambere ry’ikoranabuhanga ryo gushonga no gutera imiti, igitambaro cya PP gishonga kandi gitera imiti gifite ubushobozi bwo kuvura amazi gishobora gukorwa hakoreshejwe inyongeramusaruro zihagije zituma amazi ahuha, zishobora gukoreshwa mu bitaro, mu byumba bisukura cyane, mu bice bigezweho, mu byuma no mu byumba bya mudasobwa.
