China ndi dziko lomwe limagwiritsa ntchito kwambiri zinthu zansalu zosalukidwa zosungunula, pomwe munthu aliyense amagwiritsa ntchito nsalu zosalukidwa zosungunuka zopitirira 1.5kg. Ngakhale kuti pali kusiyana pakati pa China ndi mayiko otukuka monga Europe ndi United States, kukula kwa zinthu n'koonekeratu, zomwe zikusonyezanso kuti makampani opanga nsalu zosalukidwa zosungunuka ku China ali ndi malo ambiri.
Chifukwa cha mitengo yokwera yogulira zida komanso mtengo wokwera wopangira ndi kugwiritsa ntchito, mtengo wokwera wa zinthu zopopera zosungunuka, pamodzi ndi kusamvetsetsa momwe zinthu zimagwirira ntchito komanso momwe zimagwiritsidwira ntchito, zimapangitsa kuti msika wopopera wosungunuka usatsegulidwe, ndipo mabizinesi ena okhudzana nawo akuvutika, akuvutika kugwira ntchito. Izi ndi kusanthula kwa momwe zinthu zikuyendera pakukula kwa makampani opanga nsalu zopanda nsalu zosungunuka.
Nsalu yosalukidwa yothiridwa ndi kusungunuka ndiyo "mtima" wa masks opangira opaleshoni ndi masks a N95. Kusanthula kwa makampani opanga nsalu zosalukidwa zothiridwa ndi kusungunuka kukuwonetsa kuti nsalu yosalukidwa yothiridwa ndi kusungunuka yofunika kwambiri ya masks azachipatala ili ndi mabizinesi ochepa opereka.
Kupanga zinthu zopangidwa ndi nsalu zopanda nsalu ku China kuli ndi mitundu iwiri ya nsalu zosasunthika komanso zosasinthasintha, zomwe zimapangidwa ndi makampani ambiri, ndipo mbali zina za nsaluzi zimagulitsidwa kunja. Chifukwa cha kusintha kwa kapangidwe ka zinthu ku China m'zaka zaposachedwa, nsalu zopanda nsalu zopanda nsalu zapakhomo zawonjezeka pang'onopang'ono. Kukula kwa makampani opanga nsalu zopanda nsalu zosungunuka kumafufuzidwa kuchokera ku ntchito zazikulu zisanu.
1. Kugwiritsa ntchito m'munda woyeretsera mpweya
Kusanthula kwa momwe zinthu zikuyendera pakukula kwa makampani opanga nsalu zosalukidwa ndi kusungunuka, zomwe zimagwiritsidwa ntchito mu zotsukira mpweya, ngati maziko a fyuluta ya mpweya yogwira ntchito bwino kwambiri komanso yogwira ntchito bwino kwambiri komanso yogwiritsidwa ntchito posefera mpweya wochuluka komanso wapakatikati womwe umayenda bwino kwambiri.
Ili ndi ubwino wochepa mphamvu, mphamvu zambiri, kukana asidi ndi alkaline bwino, kukana dzimbiri, kugwira ntchito bwino, nthawi yayitali komanso mtengo wotsika. Palibe vuto la fyuluta lomwe limakhala lalifupi kwambiri lomwe zinthu zosefera zimagwera mu mpweya woyeretsedwa.
2. Kugwiritsa ntchito m'munda wa zamankhwala ndi zaumoyo
Pakamwa pake popanda fumbi, kopangidwa ndi nsalu yosungunuka ndi kupopera, kumakhala ndi mphamvu zochepa zopumira, sikudzaza mpweya, komanso kulimba kwa fumbi mpaka 99%. Kumagwiritsidwa ntchito kwambiri m'zipatala, kukonza chakudya, migodi ndi malo ena ogwirira ntchito omwe amafunika kutetezedwa ku fumbi komanso mabakiteriya.
Chogulitsachi chimapangidwa ndi filimu yoletsa kutupa komanso yochepetsa ululu pambuyo polandira chithandizo chapadera, yokhala ndi mpweya wabwino wolowera, zotsatira zoyipa zopanda poizoni komanso zosavuta kugwiritsa ntchito. Zinthu za SMS zophatikizidwa ndi nsalu yopangidwa ndi spunbonded zimagwiritsidwa ntchito kwambiri popanga zovala za opaleshoni ndi zipewa ndi zinthu zina zaukhondo.
3. Zipangizo zosefera zamadzimadzi ndi diaphragm ya batri
Nsalu yosungunula ya polypropylene imagwiritsidwa ntchito kusefa madzi a acid ndi alkaline, mafuta, mafuta ndi zina zabwino kwambiri, yawonedwa ngati chinthu chabwino cha nembanemba ndi makampani opanga mabatire kunyumba ndi kunja, ndipo yagwiritsidwa ntchito kwambiri, osati kungochepetsa mtengo wa batire, kupangitsa kuti ntchitoyi ikhale yosavuta, komanso kuchepetsa kwambiri kulemera ndi kuchuluka kwa batire.
4. Zipangizo zoyamwa mafuta ndi nsalu yopukutira ya mafakitale
Zipangizo zonse zoyamwa mafuta zopangidwa ndi nsalu yosungunula ndi kupopera ya polypropylene zimatha kuyamwa mafuta mpaka kuwirikiza ka 14-15 kuposa kulemera kwake. Zimagwiritsidwa ntchito kwambiri mu uinjiniya woteteza chilengedwe komanso uinjiniya wolekanitsa mafuta ndi madzi. Kuphatikiza apo, zitha kugwiritsidwa ntchito ngati zinthu zoyera zamafuta ndi fumbi popanga mafakitale. Ntchito izi zimathandizira kwambiri momwe polypropylene yokha imagwirira ntchito komanso momwe ulusi wa ultrafine umayamwidwira womwe umapangidwa posungunula ndi kupopera.
5. Zipangizo zotenthetsera kutentha
Ulusi wapakati wa ulusi wosungunuka wa jet ultrafine uli pakati pa 0.5 ndi 5m, ndipo malo enieniwo ndi akulu. Ma pores ambiri ang'onoang'ono amapangidwa mu nsalu, ndipo ma pores ndi okwera. Kapangidwe kameneka kamasunga mpweya wambiri, kamatha kupewa kutaya kutentha, kamasunga kutentha bwino, kamagwiritsidwa ntchito kwambiri popanga zovala komanso zinthu zosiyanasiyana zotetezera kutentha.
Kusanthula kwa momwe zinthu zikuyendera pakukula kwa makampani opanga nsalu zosalukidwa monga jekete lachikopa, jekete la ski, zovala zozizira, nsalu ya thonje, ndi zina zotero, kuli ndi ubwino wolemera pang'ono, kutentha, kusayamwa chinyezi, kulowa bwino kwa mpweya, komanso kusayamwa bowa.
Polimbana ndi mliriwu, nsalu zopanda ulusi zomwe zimapopedwa ndi kusungunuka zawonetsa ntchito zabwino kwambiri zoteteza komanso zodzipatula, zadziwikanso ndi kukondedwa ndi msika, ndipo zapangitsa kuti pakhale kukula kwakukulu.
