ʻO ka lole hoʻoheheʻe ʻole i ulana ʻia ʻo ia ka papa kānana kumu o nā masks!
He lole i ulana ʻole ʻia
Hana ʻia ka lole i hoʻoheheʻe ʻia me ka polypropylene ma ke ʻano he kumu nui, a hiki i ke anawaena fiber ke hiki i 1-5 microns. ʻO ka ultrafine fibers me ka hoʻolālā capillary kū hoʻokahi he nui nā āpau, ka fluffy structure, a me ke kūpaʻa wrinkle maikaʻi, e hoʻonui ai i ka helu a me ka ʻili o nā fibers i kēlā me kēia ʻāpana, no laila e hana ai ka meltblown i kāna kānana maikaʻi, pale, insulation, a me nā waiwai absorption ʻaila. Hiki ke hoʻohana ʻia i nā kahua e like me ka ea a me nā mea kānana wai, nā mea hoʻokaʻawale, nā mea absorbent, nā mea mask, nā mea insulation, nā mea hoʻoheheʻe ʻaila, a me nā lole holoi.
ʻO ke kaʻina hana o ka lole hoʻoheheʻe ʻole i ulana ʻia: hānai polymer - hoʻoheheʻe hoʻoheheʻe - hoʻokumu ʻana i ka fiber - hoʻoluʻu fiber - hoʻokumu pūnaewele - hoʻoikaika i ka lole.
Laulā noi
(1) Nā lole lapaʻau a me ka hoʻomaʻemaʻe: nā ʻaʻahu hoʻomaʻemaʻe, nā lole pale, nā ʻeke disinfectant, nā maka, nā diapers, nā napkin hoʻomaʻemaʻe wahine, etc.
(2) Nā lole hoʻonani hale: nā uhi pā, nā pākaukau, nā pā moe, nā moena moe, a pēlā aku;
(3) Nā lole lole: lining, lining adhesive, floc, shaping cotton, nā lole kumu ʻili synthetic, etc.
(4) Nā lole ʻenehana: nā mea kānana, nā mea insulation, nā ʻeke ʻeke sima, nā geotextiles, nā lole kāwili, a me nā mea ʻē aʻe;
(5) Nā lole mahiʻai: ka lole pale hua, ka lole hānai hua, ka lole irrigation, nā pale insulation, etc.
(6) ʻO nā mea ʻē aʻe: ka pulupulu ākea, ka insulation a me nā mea hoʻopaʻa leo, ka manaʻo o ka ʻaila, nā kānana cigarette, nā ʻeke kī, etc.
Hiki ke kapa ʻia ka lole Meltblown ʻo ka "naʻau" o nā masks surgical medical a me nā masks N95
Hoʻohana maʻamau nā maka lapaʻau lapaʻau a me nā masks N95 i kahi hoʻolālā multi-layer, i hoʻopau ʻia e like me ka hoʻolālā SMS: ʻo nā ʻaoʻao o loko a me waho he mau papa spunbond one-layer (S); ʻO ka papa waena ka papa hoʻoheheʻe ʻia (M), ka mea maʻamau i māhele ʻia i hoʻokahi papa a i ʻole nā papa he nui.
Hana ʻia nā masks pālahalaha me ka PP spunbond + melt blown + PP spunbond, a i ʻole nā filaha pōkole hiki ke hoʻohana ʻia i hoʻokahi papa e hoʻomaikaʻi ai i ke ʻano o ka ʻili. Hana ʻia kahi ʻāpana kīʻaha kīʻaha ʻekolu me ka PET polyester needle punched cotton+meltblown+needle punched cotton a i ʻole PP spunbond. I waena o lākou, ua hana ʻia ka ʻaoʻao o waho me ka lole i ulana ʻole ʻia me ka mālama ʻana i ka wai, hoʻohana nui ʻia e hoʻokaʻawale i nā droplets i kāpī ʻia e nā maʻi; ʻO ka papa waena o ka meltblown he mea hana kūikawā meltblown non-woven fabric me ka kānana maikaʻi loa, pale, insulation, a me nā waiwai absorption oil, he mea waiwai nui ia no ka hana ʻana i nā masks; Hana ʻia ka ʻāpana o loko i ka lole maʻamau ʻole.
ʻOiai ʻo ka spunbond layer (S) a me ka meltblown layer (M) o ka mask he mau lole i ulana ʻole ʻia a hana ʻia me ka polypropylene, ʻaʻole like kā lākou hana hana.
Ma waena o lākou, he mānoanoa ke anawaena o nā ʻāpana spunbond layer ma nā ʻaoʻao ʻelua, ma kahi o 20 microns; He 2 microns wale nō ke anawaena o ka pulupulu hehee i puhi ʻia ma ka waena, i hana ʻia me kahi mea polypropylene i kapa ʻia ʻo ka momona momona momona.
Ke kūlana hoʻomohala ʻana o nā lole i ulana ʻole ʻia ma Kina
ʻO Kina ka mea hana nui loa o ka honua i nā lole i ulana ʻole ʻia, me ka nui o ka hana ʻana ma kahi o 5.94 miliona tons i ka makahiki 2018, akā haʻahaʻa loa ka hana ʻana o nā lole i ulana ʻole ʻia.
Wahi a ka ʻikepili o ka Hui ʻOihana Hana Hana Hana Hana Hana, ʻo ke kaʻina hana o ka ʻoihana lole i ulana ʻole ʻia o Kina he spunbond. Ma 2018, ʻo ka hana ʻana o ka lole spunbond nonwoven he 2.9712 miliona tons, ʻo ia ka 50% o ka nui o ka hana lole nonwoven, i hoʻohana nui ʻia i nā kula o nā mea maʻemaʻe, etc. ʻO ka hapa o ka ʻenehana hoʻoheheʻe ʻia he 0.9% wale nō.
Ma muli o kēia helu ʻana, ʻo ka hana kūloko o nā lole i hoʻoheheʻe ʻia i ka 2018 he 53500 tons i kēlā me kēia makahiki. ʻAʻole hoʻohana wale ʻia kēia mau lole meltblown no nā masks, akā no nā mea palekana kaiapuni, nā mea lole, nā mea hoʻokaʻawale pākaukau, nā mea holoi holoi, etc.
Ma lalo o ka maʻi ahulau, ua hoʻonui nui ʻia ka noi no nā masks. Wahi a ka ʻikepili helu helu ʻāina ʻehā, ʻoi aku ka kiʻekiʻe o ka heluna kanaka hana o nā hui kānāwai kūloko a me nā ʻoihana pilikino e like me 533 miliona mau kānaka. Hoʻohālikelike ʻia e pili ana i hoʻokahi mask i kēlā me kēia kanaka i kēlā me kēia lā, ma kahi o 533 miliona mau masks e pono ai i kēlā me kēia lā.
Wahi a ka ʻikepili mai ka Ministry of Industry and Information Technology, ʻo ka nui o ka hana o kēlā me kēia lā o nā masks ma Kina i kēia manawa he 20 miliona.
Aia ka hapa nui o nā masks, a ua hoʻomaka nā hui he nui e hana i nā masks ma nā palena. Wahi a Tianyancha data, e pili ana i nā loli i ka ʻike hoʻopaʻa inoa ʻoihana, mai Ianuali 1 a Pepeluali 7, 2020, ʻoi aku ma mua o 3000 mau ʻoihana a puni ka ʻāina i hoʻohui i nā ʻoihana e like me "masks, lole pale, disinfectants, thermometers, a me nā mea lapaʻau" i kā lākou ʻoihana.
Hoʻohālikelike ʻia me nā mea hana mask, ʻaʻohe nui o nā ʻoihana hana lole i ulana ʻole ʻia. Ma kēia kūlana, ua hoʻoneʻe ke aupuni i kekahi mau ʻoihana kumu e hoʻomaka piha i ka hana a hoʻonui i ka hiki ke hana. Eia nō naʻe, i kēia manawa, ke kū nei i ka noi no nā lole i ulana ʻole ʻia ma nā papa lole a ma waena o nā mea hoihoi textile, ʻaʻole ia he manaʻo. Ke kū nei ka wikiwiki o ka hana ʻana o Kina i nā luʻi i ʻike ʻole ʻia i kēia maʻi maʻi! Akā ke manaʻoʻiʻo nei au i mua o kahi kūlana e hoʻomaikaʻi mālie ana, e ʻoi aku ka maikaʻi o nā mea a pau.
