Kodi nsalu yopanda ulusi yosungunuka yopangidwa ndi meltblown pa masks ndi yotani? JINHAOCHENG

Popeza kachilombo ka Coronavirus kakufalikira,zophimba nkhopeZakhala chida chofunikira kwambiri choteteza anthu. Mwadzidzidzi, masks a nkhope akhala chinthu chosowa pamsika. Ndipo kupanga masks a zinthu zopangira nsalu zopanda nsalu zosungunuka, chifukwa cha kusiyana kwakukulu, pa intaneti kwakhala kovuta, komanso kovuta.

Mliriwu usanachitike, anthu ochepa okha ndi omwe ankaudziwa. Mliriwu utatha, ankadziwa kuti unali chinthu chapadera chopangira zigoba.

Kodi ukadaulo wa meltblown nonwoven ndi wotani?

Zotsatirazi zikutsatirachosaluka chosungunukawopanga nsalu kuti amvetse:

Njira yosungunula ufa: nsalu yosefera ya polypropylene fiber ya ultrafine, chifukwa ndi yopangidwa ndi makampani opanga nsalu, ndi nsalu yopanda ulusi, njira yake ndi njira yosungunula ufa, dzina lonse: nsalu yopanda ulusi yosungunula ufa.

Pali mitundu yambiri ya nsalu zopanda ulusi zomwe zimagwiritsidwa ntchito kwambiri. Nsalu zopanda ulusi zomwe zimagwiritsidwa ntchito popanga zigoba ndi nsalu zosefera za polypropylene fiber zomwe zatchulidwa pamwambapa, zomwe zimakwaniritsa zofunikira za zigoba.

Ndiye kodi nsalu yopanda nsalu yopangidwa ndi meltblown yomwe imagwiritsidwa ntchito ngati chigoba ndi yotani?

1. Zipangizo: zigwirizane ndi muyezo waukhondo;

2. Kulowa kwa mpweya (kuchuluka kwa mpweya): kupitirira 95%;

3. Kukana: pansi pa 40Pa;

4. Zinthu zabwino zosakhala ndi madzi.

Chifukwa chake, ukadaulo wa nsalu yosefera ya polypropylene fiber filter umakwaniritsa zofunikira pakupanga masks. Ngati chigobacho chapangidwa ndi nsalu yosalukidwa yosungunuka yokha, sichingakwaniritse zofunikira paubwino.

N’chifukwa chiyani chigoba chiyenera kupangidwa ndi "nsalu yosungunula ya polypropylene fiber filter"?

Chifukwa, kuchokera ku khalidwe la zinthu, chizindikiro chachikulu cha polypropylene ulusi, chomwe chimagwirizana ndi muyezo wabwino, wowopsa, wopanda kukoma, komanso wonyansa wamadzi ndi bwino kudikira chizindikiro.

Kuchokera pakupanga, njira yosungunula imatengedwa, chifukwa njira yosungunula imayendera: makamaka kudzera mu: kusungunula - jet - draft kuti ifike pamlingo wa ulusi wabwino kwambiri, ndipo nsalu yolukidwa imapangidwa ndi kutentha kwake, kotero mpweya wabwino umalowa bwino komanso kusefa bwino kwambiri. Njira zina zopangira zimakhala zovuta kuzikwaniritsa.

Zomwe zili pamwambapa ndi chiyambi chachidule chansalu yopanda ulusi yosungunukaNdikukhulupirira kuti mudzakonda. Ndife akatswiri opanga nsalu zopanda nsalu zosungunuka zomwe zimasungunuka.Ngati mukufuna kugula, chonde titumizireni nthawi yomweyo. Musazengereze ~ tikhoza kukutumizirani zitsanzo kwaulere ~
