Kodi nsalu yosalukidwa yosungunuka yomwe dziko lonse lapansi ikuyang'ana ndi chiyani?

Nsalu zosalukidwa zosungunuka ndizomwe zimasefa pachimake!

Sungunulani nsalu zopanda nsalu zowombedwa

Sungunulani nsalu yowomberedwa makamaka imapangidwa ndi polypropylene monga zopangira zazikulu, ndipo makulidwe ake amatha kufika ma microns 1-5. Ulusi wa ultrafine wokhala ndi mawonekedwe apadera a capillary uli ndi mipata yambiri, kapangidwe ka fluffy, komanso kukana bwino kwa makwinya, zomwe zimawonjezera kuchuluka ndi malo a ulusi pagawo lililonse, motero zimapangitsa kuti nsalu yosungunuka ikhale ndi kusefa kwabwino, kutchingira, kutsekereza, komanso kuyamwa mafuta. Itha kugwiritsidwa ntchito m'magawo monga zida zosefera mpweya ndi zamadzimadzi, zida zodzipatula, zida zoyamwitsa, zida zogoba, zotsekera, zotengera mafuta, ndi nsalu zopukutira.

Njira yosungunula nsalu yopanda nsalu: kudyetsa polima - kusungunula - kusungunula - kupanga CHIKWANGWANI - kuziziritsa kwa ulusi - kupanga ukonde - kulimbikitsa kukhala nsalu.

Kuchuluka kwa ntchito

(1) Nsalu zachipatala ndi zaukhondo: mikanjo ya opaleshoni, zovala zotetezera, matumba ophera tizilombo, masks, matewera, zopukutira zaukhondo za amayi, ndi zina zotero;

(2) Nsalu zokongoletsa kunyumba: zotchingira khoma, nsalu zatebulo, zoyala, zoyala, ndi zina;

(3) Zovala zovala: akalowa, zomatira akalowa, floc, kuumba thonje, zosiyanasiyana kupanga nsalu zikopa m'munsi, etc;

(4) nsalu Industrial: zosefera zipangizo, kutchinjiriza zipangizo, matumba ma CD simenti, geotextiles, kuzimata nsalu, etc;

(5) Nsalu zaulimi: nsalu yoteteza mbewu, nsalu yokwezera mbande, nsalu yothirira, nsalu zotchingira, etc;

(6) Ena: thonje danga, kutchinjiriza ndi soundproofing zipangizo, mafuta kuyamwa anamva, zosefera ndudu, matumba tiyi, etc.

Nsalu ya Meltblown imatha kutchedwa "mtima" wa masks opangira opaleshoni ndi masks a N95

Masks opangira opaleshoni azachipatala ndi masks a N95 nthawi zambiri amatenga mawonekedwe osanjikiza angapo, ofupikitsidwa ngati mawonekedwe a SMS: mbali zamkati ndi zakunja ndi zigawo za spunbond (S); Chigawo chapakati ndi chosanjikiza chosungunuka (M), chomwe chimagawika m'magulu amodzi kapena angapo.

Masks am'nyumba nthawi zambiri amapangidwa ndi PP spunbond+melt blown+PP spunbond, kapena ulusi waufupi ungagwiritsidwe ntchito limodzi kuti ukhale wowoneka bwino. Chigoba chokhala ngati chikho cha mbali zitatu nthawi zambiri chimapangidwa ndi singano ya PET polyester yokhomeredwa thonje + meltblown + singano yokhomeredwa thonje kapena PP spunbond. Pakati pawo, wosanjikiza wakunja amapangidwa ndi nsalu sanali nsalu ndi mankhwala madzi, makamaka ntchito kudzipatula m'malovu sprayed ndi odwala; Chosanjikiza chapakati cha meltblown ndi nsalu yopangidwa mwapadera yosungunuka yosalukidwa yokhala ndi zosefera, zotchingira, zotchingira, komanso kuyamwa mafuta, zomwe ndizofunikira kwambiri popangira masks; Chipinda chamkati chimapangidwa ndi nsalu wamba yopanda nsalu.

Ngakhale spunbond layer (S) ndi meltblown layer (M) ya chigoba onse ndi nsalu zosalukidwa komanso zopangidwa ndi polypropylene, kupanga kwawo sikufanana.

Pakati pawo, m'mimba mwake ulusi wosanjikiza wa spunbond mbali zonse ndi wandiweyani, mozungulira ma microns 20; M'mimba mwake wa ulusi wosungunula wapakati ndi ma microns awiri okha, opangidwa ndi polypropylene yotchedwa high melt fat fiber.

Chitukuko cha kusungunuka kwa nsalu zosalukidwa ku China

China ndiyomwe imapanga padziko lonse lapansi nsalu zosalukidwa, zomwe zimapangidwa pafupifupi matani 5.94 miliyoni mchaka cha 2018, koma kupanga kwa nsalu zosalukidwa zomwe zimasungunuka ndizochepa kwambiri.

Malinga ndi ziwerengero za China Industrial Textile Industry Association, njira yopangira makampani opanga nsalu ku China makamaka ndi spunbond. Mu 2018, kupanga spunbond nonwoven nsalu anali matani 2.9712 miliyoni, mlandu 50% ya okwana nonwoven nsalu kupanga, makamaka ntchito m'minda ya zipangizo ukhondo, etc; Gawo laukadaulo wosungunuka ndi 0.9% yokha.

Kutengera kuwerengera uku, kupanga m'nyumba kwa nsalu zosungunula zowombedwa mu 2018 zinali matani 53500 pachaka. Nsalu zosungunukazi sizimangogwiritsidwa ntchito ngati masks, komanso zida zoteteza chilengedwe, zovala, zida zolekanitsa mabatire, zopukuta, ndi zina zambiri.

Pansi pa mliriwu, kufunikira kwa masks kwakula kwambiri. Malinga ndi chiwerengero chachinayi cha kalembera wa zachuma m'dziko lonse, chiwerengero chonse cha anthu ogwira ntchito m'mabungwe azamalamulo ndi mabizinesi apaokha ndi okwera mpaka 533 miliyoni. Kuwerengera kutengera chigoba chimodzi pa munthu patsiku, masks osachepera 533 miliyoni amafunikira patsiku.

Malinga ndi kuchuluka kwa Unduna wa Zamakampani ndi Zaukadaulo Zaukadaulo, kuchuluka kwa masks tsiku lililonse ku China ndi 20 miliyoni.

Pali kuchepa kwakukulu kwa masks, ndipo makampani ambiri ayamba kupanga masks kudutsa malire. Malinga ndi chidziwitso cha Tianyancha, kutengera kusintha kwa chidziwitso cholembetsa mabizinesi, kuyambira Januware 1 mpaka February 7, 2020, mabizinesi opitilira 3000 m'dziko lonselo adawonjezera mabizinesi monga "masks, zovala zodzitchinjiriza, mankhwala opha tizilombo, ma thermometers, ndi zida zamankhwala" pamabizinesi awo.

Poyerekeza ndi opanga chigoba, palibe mabizinesi ambiri opanga nsalu zosalukidwa zosungunuka. Pakadali pano, boma lasonkhanitsa mabizinesi ena kuti ayambe kupanga ndikuwonjezera mphamvu zopanga. Komabe, pakali pano, poyang'anizana ndi kufunikira kwa nsalu zosalukidwa zosungunuka pamapulatifomu a nsalu komanso pakati pa okonda nsalu, sizikhala ndi chiyembekezo. Liwiro lakupanga ku China likukumana ndi zovuta zomwe sizinachitikepo mu mliriwu! Koma ndikukhulupirira kuti zinthu zikasintha pang'onopang'ono, zonse zikhala bwino.
