Spunbond na melt byujujwe nuburyo bubiri butandukanye bwo gukora imyenda idoda, ifite itandukaniro rikomeye mubikoresho fatizo, uburyo bwo gutunganya, imikorere yibicuruzwa, hamwe nimirima ikoreshwa.
Ihame rya spunbond no gushonga byavuzwe
Spunbond bivuga umwenda udoda ubudodo bukozwe mugukuramo ibikoresho bya polymer muburyo bwashongeshejwe, gutera ibikoresho byashongeshejwe kuri rotor cyangwa nozzle, kubimanura muburyo bwashongeshejwe hanyuma bigakomera byihuse kugirango bibe fibre fibrous, hanyuma bigahuza kandi bigahuza fibre binyuze mumashanyarazi cyangwa amashanyarazi. Ihame nugukuramo polymer yashongeshejwe binyuze muri extruder, hanyuma ukanyura mubikorwa byinshi nko gukonjesha, kurambura, no kurambura icyerekezo, amaherezo ugakora umwenda udoda.
Ku rundi ruhande, Meltblown, ni inzira yo gusohora ibikoresho bya polymer biva mu gihugu cyashongeshejwe binyuze mu muvuduko mwinshi. Bitewe n'ingaruka no gukonjesha byihuta byumuyaga mwinshi, ibikoresho bya polymer bihita bikomera mubikoresho bibi kandi bikareremba mu kirere, bigahita bitunganywa bisanzwe cyangwa bitose kugirango bibe urusobe rwiza rwa fibre idoda. Ihame ni ugutera ibikoresho byo mu rwego rwo hejuru byashongeshejwe ibikoresho bya polymer, kubirambura muri fibre nziza binyuze mu kirere cyihuta cyane, kandi bigahita byinjira mu bicuruzwa bikuze mu kirere, bigakora urwego rwibikoresho byiza bidoda.
Ibikoresho bitandukanye
Imyenda idoda idoda mubusanzwe ikoresha fibre ya chimique nka polypropilene (PP) cyangwa polyester (PET) nkibikoresho fatizo, mugihe imyenda yashonze idashushanyije ikoresha ibikoresho bya polymer muburyo bwashongeshejwe, nka polypropilene (PP) cyangwa polyacrylonitrile (PAN) .Ibisabwa kubikoresho fatizo biratandukanye. Spunbonding isaba PP kugira MF ya 20-40g / min, mugihe gushonga bisaba 400-1200g / min.
Kugereranya hagati ya fibre yashonze na fibre spunbond
A. Uburebure bwa fibre - kuzunguruka nka filament, gushonga bihuha nka fibre ngufi
B. Imbaraga za fibre: Imbaraga za fibre spunbonded> Imbaraga za fibre
C. Ubwiza bwa fibre: Fibre yashonze iruta fibre spunbond
Uburyo butandukanye bwo gutunganya
Gutunganya imyenda idahwitse irimo gushonga fibre ya chimique mubushyuhe bwinshi, kuyishushanya, hanyuma ugakora imiyoboro ya fibre binyuze mu gukonjesha no kurambura; Gushonga byavanze bitarimo imyenda ni inzira yo gutera ibikoresho bya polymer bishongeshejwe mukirere binyuze mu muvuduko wihuse, gukonjesha vuba no kubirambura mumibiri myiza bitewe nigikorwa cyumuvuduko mwinshi wihuta, amaherezo ugakora urwego rwimiterere ya fibre yuzuye.
Kimwe mu biranga imyenda yashongeshejwe idoda idoze ni uko ubwiza bwa fibre ari buto, ubusanzwe buri munsi ya 10nm (micrometero), kandi fibre nyinshi zifite ubwiza bwa 1-4 rm.
Imbaraga zinyuranye kumurongo wose uzunguruka kuva gushonga nozzle kugeza kubikoresho byakira ntibishobora kuringanizwa (kubera ihindagurika ryingufu zingutu zubushyuhe bwo hejuru hamwe numuvuduko mwinshi mwinshi, umuvuduko nubushyuhe bwumwuka ukonje, nibindi), bikavamo ubwiza bwa fibre butaringaniye.
Uburinganire bwa fibre ya fibre muri spunbond idoda idoda neza ni nziza cyane kuruta iy'ibikoresho bya spray, kubera ko mugihe cya spunbond, uburyo bwo kuzunguruka bumeze neza, kandi impinduka mugutegura no gukonjesha ni nto.
Kuzunguruka byuzuye biratandukanye. Gushonga gushonga ni 50-80 ℃ hejuru kuruta kuzunguruka.
Kurambura umuvuduko wa fibre biratandukanye. Kuzunguruka ifunguro 6000m / min, gushonga byavanze 30Km / min.
Umwami w'abami yarambuye intera ariko ntashobora kubigenzura. Kuzunguruka 2-4m, guhuza 10-30cm.
Imiterere yo gukonjesha no gukurura iratandukanye. Fibre ya Spinnbond ikururwa numwuka mwiza / utari mwiza ukonje kuri 16 ℃, mugihe fuse ihuhwa numwuka mwiza / mubi ushyushye hafi 200 ℃.
Imikorere itandukanye
Imyenda idoda idoze mubusanzwe ifite imbaraga zo kuvunika no kuramba, ariko imiterere nuburinganire bwa fibre mesh irashobora kuba mibi, ibyo bikaba bikenerwa nibicuruzwa bigezweho nkimifuka yo guhaha; Umwenda ushongeshejwe udoda ubudodo ufite guhumeka neza, kuyungurura, kwambara birwanya, hamwe na anti-static, ariko birashobora kugira imbaraga zamaboko n'imbaraga, kandi birashobora gukoreshwa mugukora masike yubuvuzi nibindi bicuruzwa.
Imirima itandukanye
Imyenda idoda idoda idoda ikoreshwa cyane mubuvuzi, imyambaro, urugo, inganda nizindi nzego, nka masike, amakanzu yo kubaga, ibipfukisho bya sofa, ibitambara, nibindi; Imyenda yashongeshejwe idoda idoda ikoreshwa cyane cyane mubuvuzi, ubuzima, kurengera, kurengera ibidukikije nizindi nzego, nka masike yo mu rwego rwo hejuru, imyenda irinda, kuyungurura, nibindi.
Umwanzuro
Gushonga byashizwemo imyenda idoda hamwe na spunbond idoda idoda ni ibikoresho bibiri bitandukanye bidoda imyenda hamwe nibikorwa bitandukanye byo gukora nibiranga. Kubijyanye no gusaba no gutoranya, birakenewe ko dusuzuma byimazeyo ibikenewe hamwe nibikoreshwa, hanyuma ugahitamo ibikoresho bidakwiriye bidoda.
