Nā pale makahe mau lole i ulana ʻole ʻia, ʻo ia nā lole i ulana ʻole ʻia e kūʻē i nā lole textile, a ua haku ʻia me nā olonā kuhikuhi a i ʻole nā loloa kaulele.
ʻO nā pale maka lapaʻau he mau ʻano hana he nui nā papa, i kapa pinepine ʻia ʻo nā ʻano hana SMS (2 S a me 1 M papa). I kēia manawa, ʻo ka helu kiʻekiʻe loa o nā papa ma Kina he 5, ʻo ia hoʻi ʻo SMMMS (2 S papa a me 3 M papa).
He aha ka SMS?
Maanei, ʻo S ke kū nei no ka papa Spunbond. He mānoanoa iki ke anawaena o ka fiber, ma kahi o 20 microns (m). ʻO ka hana nui o nā papa Spunbond 2 S ke kākoʻo i ka ʻōnaehana lole i ulana ʻole ʻia, ʻaʻohe hopena nui i ka pale. ʻO ka ʻāpana koʻikoʻi o ka pale maka ʻo ia ka papa pale a i ʻole ka papa Meltblown M (papa Meltblown). He lahilahi iki ke anawaena o ka papa pīpī hoʻoheheʻe ʻia, ma kahi o 2 microns (M), no laila he hapaʻumi wale nō ia o ke anawaena o ka papa spunbonding, kahi e pāʻani ai i kahi hana koʻikoʻi i ka pale ʻana i ka bacteria a me ke komo ʻana o ke koko.
Hoʻohana pinepine nā masks lapaʻau maʻamau i ka lole pīpī hoʻoheheʻe he 20 grams ke kaupaona ʻana, hoʻohana nā masks kīʻaha N95 i ka lole pīpī hoʻoheheʻe he 40 grams a ʻoi aku paha.
Wahi a nā helu helu o ka China Industrial Textile Industry Association, ma ka hopena o 2018, aia he 1,477 mau laina hana spunbonded kūloko, 65 ʻoi aku ma mua o ka makahiki i hala, me ka piʻi ʻana o 4.6% i kēlā me kēia makahiki, ma waena o ia mau mea, ua hoʻonui ʻia ka laina hana PP spunbonded non-wovens e 3.38%, ka laina hana composite SMS ma kahi kokoke i 13%, a me ka laina hana PET spunbonded non-wovens ma 9.32%. Ua piʻi pū ka nui o nā ʻoihana me ka hana makahiki ma mua o 50,000 tons mai ka makahiki 2017. Ke wikiwiki nei nā ʻoihana Spunbonded i kā lākou hoʻomohala ʻana i ka unahi, ka hoʻoikaika ʻana a me ke kiʻekiʻe e hoʻokō i ke koi o ka mākeke no ka hoʻonui ʻana i ka huahana a me ka hoʻonui ʻana i ka ʻenehana.
Mai ka makahiki 2018, ua hoʻomohala nā ʻoihana kūloko he nui i kā lākou huahana ma ke ala o ka māmā, lahilahi a me ka hana kiʻekiʻe, a ua hoʻokō i nā hopena maikaʻi. Ke hana nei ka SSMMS spunbonded/molten shotcreting composite process 600m/min a ʻoi aku paha ka hana wikiwiki; Ma kahi o 10 grams no ka mika kūlike super palupalu nā huahana paʻa paʻa.
Mai hea mai ka lole ulana ʻole SMS?
Nā lole ulana ʻole SMSHana nui ʻia mai ka polypropylene PP (me nā waiwai bacteriostatic kūlohelohe a me ka hydrophobicity), a hiki i ke anawaena o nā olonā ke hiki i ka 0.5-10 microns. ʻO kēia mau olonā ultrafine me ka capillarity kū hoʻokahi e hoʻonui i ka nui a me ka ʻili o nā olonā ma kēlā me kēia ʻāpana, no laila e hana ana i nā lole i hoʻoheheʻe ʻia i ka hoʻoheheʻe ʻia he mau waiwai kānana ea maikaʻi, e hana ana iā lākou i mea mask maikaʻi.
I kēia manawa, aia ʻekolu mau kaʻina hana nui no ka hana ʻana i nā huahana SMS (lole ulana ʻole SMS): "kaʻina hana hoʻokahi-ʻanuʻu", "kaʻina hana ʻelua-ʻanuʻu" a me "kaʻina hana hoʻokahi a me ka hapa".
ʻO nā hiʻohiʻona hoʻokahi-ʻanuʻu ka hoʻohana ʻana i ka ʻāpana mea maka o kēia kaʻina hana, me ka hoʻohana ʻana i ʻelua ʻenehana milo-pili, puhi-hoʻoheheʻe ʻia, milo pololei i nā mea maka ma hope o ka hoʻoheheʻe ʻana i loko o nā ʻupena, inā he hoʻonohonoho kūpono o nā kaʻina hana like ʻole o ka ʻenekinia ʻōnaehana milo, a hiki ke hana i nā huahana me ke ʻano like ʻole, ʻo kēlā me kēia papa lole laminated composite, ʻo ia ka hoʻohui ʻana me kahi wili wela i loko o ka lole. "ʻO ke ʻano hana hoʻokahi-ʻanuʻu" i hōʻike ʻia e ka hoʻoheheʻe pololei ʻana i loko o kahi ʻupena, hiki ke hoʻoponopono kūʻokoʻa i ke kūlana o kēlā me kēia ʻōnaehana milo, ka mana ikaika o ke kaʻina hana, nā kūlana olakino maikaʻi, ka wikiwiki kiʻekiʻe, hiki ke hoʻoponopono i ka hapa o kēlā me kēia papa o ka ʻupena fiber, hiki ke hana i nā huahana ʻano SMS o nā kikoʻī like ʻole, ʻo ia ka ʻenehana nui i kēia lā.
Kaʻina hana ʻelua-ʻanuʻu: Ke hoʻohana nei i ke kaʻina hana ʻelua-ʻanuʻu e hana i nā huahana SMS, ua wehe ʻia nā huahana i hoʻopau ʻia o ka lole spunbonded a me ka lole i hoʻoheheʻe ʻia i loko o kahi ʻano, a laila laminated i loko o kahi kaʻina, a laila hoʻopaʻa ʻia me kahi wili wela, a hoʻohui ʻia i loko o nā huahana SMS. Hoʻohālikelike ʻia ke ʻano hana ʻelua-ʻanuʻu e nā lako maʻalahi a me ke kumukūʻai haʻahaʻa. ʻO ka ʻoiaʻiʻo, ʻo ke kaʻina hana "ʻelua-ʻanuʻu" ka ʻenehana lamination composite i hoʻohana nui ʻia, akā hiki ke hui pū ʻia me nā mea ʻē aʻe, me nā mea ʻē aʻe like ʻole, a me nā ʻano hana like ʻole, e like me ka ultrasonic, hot melt adhesive ʻekolu papa o nā mea i hui pū ʻia.
ʻAno hana hoʻokahi a me ka hapa: ma ke ʻano hana ʻelua-ʻanuʻu, hiki nō hoʻi ke hoʻololi i ka huahana lole pīpī hoʻoheheʻe ʻia me ka ʻupena fiber papa pīpī hoʻoheheʻe ʻia i hana ʻia ma ke kula, no laila ua loaʻa ke kaʻina hana i kapa ʻia ʻo "ʻano hana hapa". Hoʻohana ʻia ka lole spunbonded ma ke ʻano he papa lalo a me ka papa ʻili e nā mea wehe ʻelua, a ʻo ka ʻupena fiber pīpī hoʻoheheʻe o ka papa waena e milo pololei ʻia i loko o kahi ʻupena e ka ʻōnaehana pīpī hoʻoheheʻe, waiho ʻia ma ka papa lalo o ka lole spunbonded, a laila uhi ʻia me ka papa luna o ka lole spunbonded, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i kahi wili wela i hoʻohui ʻia i loko o nā huahana SMS.
