Ni izihe mpamvu zo gukoresha cyane polipropilene mu buhanga bwa elegitoronike?

Ihame ry'umusaruro w'igitambara gishonga

Umwenda wa Meltblown ni ibikoresho bishonga polymers ku bushyuhe bwinshi hanyuma ukabisuka muri fibre munsi yumuvuduko mwinshi. Izi fibre zirakonja vuba kandi zigakomera mu kirere, zigakora umuyoboro mwinshi wa fibre. Ibi bikoresho ntabwo bifite imikorere myiza yo kuyungurura gusa, ariko kandi biroroshye kandi bihumeka, kuburyo bikwiriye gukoreshwa mubikoresho birinda nka mask.

Ibikoresho nyamukuru byibanze kumyenda yashonze

Ibikoresho by'ibanze by'imyenda yashonze ni polypropilene, ikunze kwitwa ibikoresho bya PP. Kugeza ubu, imyenda isanzwe ya mask ya masike kumasoko ikoresha polipropilene imyenda ya elegitoronike nkibikoresho byo kuyungurura. Impamvu yo guhitamo polypropilene nkibikoresho nyamukuru ni uko ifite imikorere myiza yo gutunganya nibyiza byigiciro, kandi ugereranije nibidukikije.

Usibye polypropilene, imyenda ya meltblown irashobora kandi gukorwa mubindi bikoresho nka polyester, nylon, imyenda, n'ibindi. Ariko, ugereranije na polypropilene, ibyo bikoresho bifite amafaranga menshi cyangwa imikorere mibi yo gutunganya, bigatuma bidakwiranye n’umusaruro munini.

Polypropilene ikoreshwa cyane mubuhanga bwa elegitoronike kuko ifite ibyiza bikurikira

1. Ubukonje bwa polymer burashobora kugenzurwa no gukoresha okiside cyangwa peroxide mugikorwa cyo kuyisohora, cyangwa mugukata imashini zikoresha imashini cyangwa kugenzura ubushyuhe bwakazi kugirango ugabanye ubushyuhe bwumuriro, kugirango ugenzure ububobere bwashonga.

2. Ikwirakwizwa ryibiro bya molekuline rishobora kugenzurwa nigishishwa cyashongeshejwe imyenda idakenewe, bisaba kugabanura uburemere buke bwa molekile kugirango ubyare fibre imwe ya ultrafine. Ukoresheje tekinoroji nshya ya catalitiki nka catalizike ya metallocene, polymers ifite indangagaciro ndende cyane kandi ikwirakwiza uburemere bwa molekile irashobora kubyara.

3. Ingingo yo hejuru yo gushonga irahagije kugirango irwanye ubushyuhe bwa polypropilene kubicuruzwa byinshi, kandi ifite intera nini ya propylene yashongeshejwe. Scope rero, ni nziza cyane kubikorwa bisanzwe bikoreshwa mugutunganya amashyuza muburyo bwa tekinoroji idoda.

4. Nibyiza kubyara fibre ultrafine. Niba ibishishwa bya polypropilene bishonga ari bike kandi ikwirakwizwa ryibiro bya molekile bikaba bigufi, birashobora gukorwa mumibiri myiza cyane mugihe kimwe cyo gukoresha ingufu hamwe no kurambura mugihe cyo gushonga. Kubwibyo, fibre isanzwe ya fibre ya polypropilene yashonga ihuha idoda idoze ni 2-5um, cyangwa nziza.

5. Kugeza ubu, chipi ikoreshwa cyane ya polypropilene ifite igipimo cyo gushonga cya 400-1200g / 10min hamwe no kugabanya uburemere buke bwa molekile kugirango ikore fibre ultrafine hamwe nubucucike bukenewe.

6. Chipi ya polypropilene ikoreshwa muguhingura ibicuruzwa no kuyitunganya bigomba kuba bifite indangagaciro ndende kandi imwe, kugabanura uburemere bwa molekile, kugabanuka neza gutunganyirizwa hamwe, hamwe na chip nziza kandi ihamye kugirango habeho ituze ryibikoresho bishongeshejwe.

Kwirinda kubyara umwenda ushonga

Muburyo bwo gukora umwenda ushonga, ingingo zikurikira zigomba kwitonderwa:

1. Guhitamo ibikoresho bigomba kuba byera bihagije: Nkuko umwenda ushonga ugomba kwihanganira gushungura, birakenewe guhitamo ibikoresho bifite isuku ihagije muguhitamo ibikoresho bibisi. Niba hari umwanda mwinshi, bizagira ingaruka kumayunguruzo yimyenda yashonze.

2. Kugenzura ubushyuhe bwo gutunganya hamwe nigitutu: Ubushyuhe bwo gutunganya nigitutu bigomba gushyirwaho ukurikije ubwoko bwibikoresho fatizo kugirango habeho gukora neza fibre.

3. Kugenzura isuku mubidukikije: Nkuko umwenda ushonga ukoreshwa mugukora ibikoresho birinda nka masike, isuku mubidukikije ni ngombwa cyane. Birakenewe ko habaho isuku yamahugurwa yumusaruro kugirango twanduze ibicuruzwa.

Dongguan Liansheng Ntabwo Yubatswe Ikoranabuhanga Co, Ltd.yashinzwe muri Gicurasi 2020.Ni uruganda runini rutunganya imyenda rudahuza ubushakashatsi niterambere, umusaruro, no kugurisha. Irashobora gutanga amabara atandukanye ya PP spunbond idoda idoda hamwe n'ubugari bwa metero 3.2 kuva kuri garama 9 kugeza kuri garama 300.
