Itandukaniro hagati ya meltblown na spunbond

Imyenda ya Meltblown nigitambara kidoda mubyukuri nikintu kimwe. Umwenda wa Meltblown ufite kandi izina ryitwa meltblown idoda idoda, ikaba ari imwe mu myenda myinshi idoda.Imyenda idodani ubwoko bw'igitambara gikozwe muri polypropilene nkibikoresho fatizo, bigahinduka polymer muri meshi binyuze mu gushushanya ubushyuhe bwo hejuru, hanyuma bigahuzwa nigitambara hakoreshejwe uburyo bwo kuzunguruka.

Ikoranabuhanga ritandukanye

Imyenda idoda kandi idashonga imyenda idoda ni ubwoko bwombi bwimyenda idoda, ariko uburyo bwo gukora buratandukanye.

(1) Ibisabwa kubikoresho fatizo biratandukanye. Spunbond isaba MFI ya 20-40g / min kuri PP, mugihe gushonga bisaba 400-1200g / min.

(2) Ubushyuhe bwo kuzunguruka buratandukanye. Gushonga gushonga ni 50-80 ℃ hejuru kuruta kuzunguruka.

(3) Umuvuduko wo kurambura fibre uratandukanye. Spunbond 6000m / min, gushonga byavutse 30km / min.

(4) Intera irambuye ntabwo ari silindrike. Kuzunguruka 2-4m, gushonga 10-30cm.

(5) Ibikonje no kurambura biratandukanye. Fibre ya spunbond ishushanywa ukoresheje 16 air umwuka ukonje hamwe nigitutu cyiza / kibi, mugihe fibre yashonze ihuha ikoresheje hafi ya 200 air umuyaga ushyushye mubyumba bikuru.

Imikorere itandukanye

Imbaraga zo kumena no kurambura imyenda ya spunbond irarenze cyane iy'imyenda yashonze, kandi igiciro ni gito. Ariko ukuboko kumva no guhuza fibre birakennye.

Imyenda ya Meltblown iroroshye kandi yoroshye, hamwe no kuyungurura cyane, kwihanganira bike, no gukora inzitizi nziza. Ariko ifite imbaraga nke kandi irwanya kwambara nabi.

Kugereranya ibiranga inzira

Kimwe mu biranga imyenda yashonze idashushanyijeho ni uko ubwiza bwa fibre ari buto, ubusanzwe buri munsi ya 10um (micrometero), hamwe na fibre nyinshi zifite ubwiza hagati ya 1-4um.

Imbaraga zinyuranye kumurongo wose uzunguruka kuva nozzle ya meltblown bapfa kugeza kubikoresho byakira ntibishobora gukomeza kuringaniza (kubera ihindagurika ryingufu zirambura ziterwa nubushyuhe bwo hejuru hamwe n’umuvuduko mwinshi w’umuyaga, kimwe n’ingaruka zo gukonjesha ikirere n’ubushyuhe), bikavamo ubwiza butandukanye bwa fibre yashonze.

Uburinganire bwa fibre diametre muri spunbond idoda idoda ni nziza cyane kurenza iy'imisemburo ya meltblown, kubera ko mugihe cya spunbond, uburyo bwo kuzunguruka bumeze neza, kandi ihindagurika mubihe byo kurambura no gukonja ni bito.

Kugereranya Crystallisation na Icyerekezo Impamyabumenyi

Ikirangantego hamwe nicyerekezo cya fibre yashonze ni ntoya kurenza iyofibre fibre. Kubwibyo, imbaraga za fibre zashongeshejwe zirakennye, kandi imbaraga za fibre web nayo irakennye. Bitewe n'imbaraga nke za fibre zishongeshejwe zidashushanyijeho, ikoreshwa ryukuri ryimyenda yashizwemo idoda idoda cyane cyane ishingiye kubiranga fibre ultrafine.

Kugereranya hagati ya fibre yashonze na fibre spunbond

Uburebure bwa fibre - spunbond ni fibre ndende, meltblown ni fibre ngufi

Imbaraga za fibre - imbaraga za spunbond fibre> imbaraga za fibre fibre

Ubwiza bwa fibre - Feltblown fibre nziza kuruta fibre spunbond

Imiterere itandukanye

1. Imbaraga nigihe kirekire: Muri rusange, imbaraga nigihe kirekire cyaimyenda idodaziri hejuru kurenza imyenda ya meltblown idoda. Imyenda idoda idoda ifite imbaraga nziza kandi irambuye, ariko izarambura kandi ihindurwe iyo ikuruwe; Nyamara, gushonga byavanze bitarimo ubudodo bifite uburebure burambuye kandi bikunda kumeneka neza iyo bikuruwe n'imbaraga.

2. Guhumeka: Imyenda idoda idoda ifite guhumeka neza kandi irashobora gukoreshwa mugukora mask yubuvuzi nibindi bicuruzwa. Nyamara, imyenda ya elegitoronike idoda idahumeka ifite umwuka mubi kandi irakwiriye kubicuruzwa nkimyenda ikingira.

3. Imyenda nuburyo: Imyenda idoda idoda ifite imyenda igoye kandi igiciro gito, ariko imiterere yayo hamwe nuburinganire bwa fibre birakennye, ibyo bikaba bihuye nibyifuzo byibicuruzwa bimwe na bimwe byerekana imideli. Imyenda ya Meltblown iroroshye kandi yoroshye, hamwe no kuyungurura cyane, kwihanganira bike, no gukora inzitizi nziza. Ariko ifite imbaraga nke kandi irwanya kwambara nabi.

4. Ubuso bwimyenda idoda muri rusange ifite utudomo tugaragara; Kandi gushonga imyenda idoda idoze ifite ubuso buringaniye hamwe nuburyo buke.

Imirima itandukanye

Bitewe nimiterere itandukanye nibiranga ubwoko bubiri bwimyenda idoda, imirima yabyo nayo iratandukanye.

1.

2. Ibindi bicuruzwa: Gukoraho byoroheje nuburyo bwimyenda ya spunbond idoda idoda ikwiriye gukora ibicuruzwa byo kwidagadura, nkibifuniko bya sofa, ibitambara, nibindi.

Umwanzuro

Muncamake, imyenda idahwitse hamwe nigitambaro cyo gushonga idafite imyenda ifite imiterere yabyo kandi ikwiranye nimirima itandukanye. Abaguzi barashobora guhitamo ibikoresho bikwiye ukurikije ibicuruzwa byabo.
