Kodi nsalu yosungunuka yomwe ili mu chigoba imapangidwa ndi nsalu yanji? JINHAOCHENG

M'zaka ziwiri zapitazi, kachilombo ka korona kakufalikira kwambiri ndipo mliri watsopano wa korona wafalikira kwambiri kumayiko ena. Ife anthu wamba tiyenera kudziteteza tokha, kusamala ndi kuvala zophimba nkhope (zophimba nkhope zotayidwa, zophimba nkhope zachipatala zotayidwa kapenaMa masks a KN95, masks a N95) ndipo samalani ndi mtunda wocheza ndi anthu, ndipo yesetsani kudziteteza nokha. Kuti mudziwe zambiri zokhudza chitetezo, mutha kuwona njira zabwino kwambiri zaku China zopewera miliri. Mwanjira imeneyi, thanzi lathu, kuphatikizapo banja lanu, anzanu, ogwira nawo ntchito, ndi zina zotero, litha kupewa kachilomboka ndikusangalala ndi moyo.

Lero, pamodzi ndi Jin Haocheng, wopangansalu yosungunuka (chovala chophimba nkhope), tiyeni tiphunzire za momwe zinthu zansalu yosungunukamu masks amapangidwa.
　
Nsalu yosungunuka imapangidwa makamaka ndi polypropylene, ndipo kukula kwa ulusi kumatha kufika ma microns 1 mpaka 5. Pali ma voids ambiri, kapangidwe kofewa, komanso mphamvu yabwino yolimbana ndi makwinya. Ulusi wopyapyala kwambiriwu wokhala ndi kapangidwe kapadera ka capillary umawonjezera kuchuluka ndi malo a ulusi pa unit department, kotero kutinsalu yosungunukaIli ndi kusefa bwino, kuteteza, kutchinjiriza kutentha komanso kuyamwa mafuta. . Ingagwiritsidwe ntchito m'minda ya mpweya, fyuluta yamadzimadzi, zipangizo zolekanitsa, zipangizo zoyamwitsa, chigoba, zipangizo zotetezera kutentha, zipangizo zoyamwitsa mafuta ndi nsalu zopukutira.

Aliyense amadziwa kuti masks azachipatala ali ndi gawo lansalu yosungunuka, ndiye ndi zinthu ziti zomwe zili muchigoba chachipatalansalu yosungunuka yopangidwa ndi?

Nsalu yosungunuka yomwe imagwiritsidwa ntchito mu chigoba imapangidwa ndi zinthu za polypropylene, ndipo nsalu yosungunuka imapangidwanso ndi zinthu za polypropylene zotchedwa high-melt fat fiber. Ndi mtundu wa nsalu ya ultra-fine electrostatic fiber, yomwe ingagwiritse ntchito bwino magetsi osasunthika kuyamwa mavairasi, fumbi, ndi madontho, ichi ndi chifukwa chofunikira chomwe masks amatha kusefa mavairasi. Ma masks azachipatala nthawi zambiri amagwiritsa ntchito kapangidwe ka multi-layer, kotchedwa SMS structure: single spunbond layer (S) mbali zonse ziwiri. Pali single layer kapena multiple meltblown layers (M) pakati. Zipangizo zabwino kwambiri za meltblown layer ndi meltblown. Ndi chinthu chachikulu chosefera ma virus masks, ndipo pakati pa M layer-meltblown non-woven nsalu. Ndipotu, zigawo zitatuzi zonse ndi nsalu zopanda ulusi, ndipo zopangira zonse ndi polypropylene, koma njira yopangira ndi yosiyana. Pakati pawo, kukula kwa ulusi wa spun-bonded layer kumbali zamkati ndi zakunja ndi kokhuthala, pafupifupi ma microns 20; M'mimba mwake mwa ulusi wosungunuka womwe uli pakati ndi ma microns awiri okha, womwe umapangidwa ndi polypropylene yotchedwa high-melt fat fiber. Ndi wofooka ndipo sungatsukidwe ndi madzi kapena kupopedwa ndi mowa. Ngakhale utanyowa komanso wouma, udzawononga minofu ya ulusi ndikuyambitsa mipata. Ngati mavairasi alowa kudzera m'mipata, chigobacho chimataya mphamvu yake yoteteza.

Popeza mliriwu uli woopsa kwambiri, masks akhala chinthu chofunikira kwambiri pa moyo wathu woyenda. Tiyeni timvetse chifukwa chake masks amatha kupewa mavairasi? Choyamba, kuchuluka kwa kachilombo ka corona ndi 80 ～120nm, chifukwa nthawi zambiri kumamatiridwa kumadzi amthupi ndikupopera. , Chifukwa chake nthawi zambiri kumakhala kwakukulu kuposa 0.1um (0.1 micron (um) = 100 nanometers (nm)). Nsalu yosungunuka imagwiritsa ntchito polypropylene ngati chinthu chachikulu chopangira, ndipo kukula kwa ulusi kumatha kufika 0.5-10um. Ngati ndi kachilombo komatiridwa kumadzi amthupi, kakhoza kusefedwa.

Kudzera mu mawu oyamba omwe ali pamwambapa, kodi mukudziwa zambiri zokhudza masks?

Kuti mudziwe zambiri zaukadaulo komanso upangiri paNsalu Yosalukidwa Yosungunuka, Chopangidwa Chosapangidwa ndi Ulusi, Nsalu Yopanda Ulusi ya Spunlace, Sefani Nsalu Yopanda Ulusi, Chopanda nsalu chopangidwa ndi singano, mwalandiridwa kuti mulumikizane ndi Jin Haocheng Non-woven Fabric. Tidzayesetsa kukuthandizani.
