Mitundu ndi kugwiritsa ntchito kwa nsalu zopanda chidwi (1)

Chovala chosaneneka / chopanda kanthu, monga zinthu zosakhala zachikhalidwe, ndizofunikira komanso zofunikira munthawi yamakono chifukwa cha ntchito zake zapadera. Amagwiritsa ntchito njira zopangira thupi kapena mankhwala kugwirizanitsa ndi kupatsirana ulusi limodzi, ndikupanga nsalu yokhala ndi mphamvu ndi zofewa. Pali njira zingapo zopanga za nsalu zosawoneka, ndipo njira zosiyanasiyana zopanga zimapereka nsalu zosakakamira zomwe sizimakumana ndi zosowa zosiyanasiyana.

M'mafakitale ambiri monga tsiku ndi tsiku, ogulitsa, ndi zomangamanga, zomwe sizikuwoneka bwino zitha kuwoneka zikugwira ntchito yawo:

1. Mu gawo laumoyo: Masks, zovala zopangira opaleshoni, zovala zoteteza, zovala zamankhwala, napasin, etc.

2. Zipangizo za zosefera: mpweya zosefera, zamadzimadzi, mafuta olekanitsidwa ndi mafuta, etc.

3. Zida za geotechnical: Network Network, anti-sentpage membrane, geotextle, etc.

4. Zovala zovala: Zingwe za zovala, zingwe, mapewa a mapewa, etc.

5. Zinthu zapakhomo: zofunda, matebulo, makatani, ndi zina zambiri.

6. Mkati mwa mkati: mipando yamagalimoto, denga, matepe, etc.

7. Ena: Zipangizo za ma CAV, Battery Olekanitsa, zinthu zamagetsi zopitira, zina zina.

Njira yayikulu yopanga nsalu zopanda chidwi zimaphatikizapo zotsatirazi:

1. Njira ya Melletblown: Njira ya Meltbown ndi njira yosungunulira majeremoplastic zitsamba, kupopera mbewu kuthamanga kwambiri kuti apange nsalu zabwino, kenako ndikugwirizanitsa pamodzi kuti apange nsalu zosakazika panthawi yozizira.

-Pandature: Polymer kudyetsa → Sungunulani poyambira → Zowonjezera → Zithunzi zozizira

- Ikuawiritsani: ulusi wabwino, magwiridwe antchito abwino.

-Mawu osefera: zida zosefera bwino, monga masks ndi zosefera zamankhwala.

2. Njira ya Spinbond: Njira ya spinbond ndi njira yosungunulira majeremusi otentha, kupanga ulusi wopitilira mtengo kwambiri, kenako ndikuziziritsa kukhosi kuti mupange mpweya wosatsukidwa.

-Patani: Polymer Pofikira → Kutambasulira kuti apange mafinya → Kulumikizana (Kudziphatika, Kulumikizana Kwa Makina). Ngati wozungulira amagwiritsidwa ntchito kugwiritsira ntchito kukakamiza, malo otentha okhazikika (ma pockimark) nthawi zambiri amawonedwa pa nsalu yopanikiza.

- Ikukwirira: mphamvu zabwino komanso zopuma zabwino kwambiri.

-Mathandizo: Zinthu zamankhwala, zovala zotayika, zinthu zina, ndi zina.

Pali zosiyana kwambiri pamicrostructuctution pakati pa nsalu zopanda chidwi zomwe zimapangidwa ndi spunbond (kumanzere) ndi njira zosungunuka pamlingo womwewo. Mu sculndind njira, ulusi ndi mipata ya manyowa ndizokulirapo kuposa zomwe zimapangidwa ndi njira ya Mellettblown. Ichi ndi chifukwa chake Meltblown osagwirizana ndi nsalu zazing'onoting'ono ndi miyala yaying'ono imasankhidwa kuti isakhale ya nsalu zopanda chidwi mkati mwa masks.
