No ke aha e pale ai nā masks i ka laha ʻana o ka maʻi?
He aha ke ʻano o ia mea?
'Ōlelo pinepine mākou ua hanaʻia nā masks i nā lole i ulanaʻoleʻia.ʻO nā lole i ulanaʻoleʻia he mau lole i ulanaʻoleʻia, e kū'ē i nā lole i ulanaʻia, i hanaʻia i nā mea i hoʻonohonohoʻia a iʻole nā mea maʻamau.
I ka hiki ʻana i nā masks, ʻo ka mea maka he Polypropylene (PP).ʻO nā masks hoʻokuʻu ʻia he Polypropylene multilayered.inoa Pelekania: Polypropylene, PP no ka pōkole, he kala ʻole, mea ʻala ʻole, ʻona ʻole, translucent paʻa paʻa, ʻo ia ka pūhui polymer i hana ʻia e ka polymerization o propylene.Hoʻohana nui ʻia ka polypropylene i ka hana ʻana i nā huahana fiber e like me nā lole a me nā pākeʻe, nā mea lapaʻau, nā kaʻa, nā paikikala, nā ʻāpana ʻokoʻa, nā paipu halihali a me nā pahu kemika, a me ka hoʻopili ʻana i nā meaʻai a me nā lāʻau lapaʻau.
Hiki ke hoʻohana ʻia ka lole i ulana ʻole ʻia e nā mea kūikawā o ka polypropylene non-woven fabric no nā lole hana hoʻopau, nā ʻāpana, nā maka, nā uhi, nā pads absorption wai a me nā lako olakino a me nā lako olakino ʻē aʻe.
ʻO nā masks i ʻike ʻia he hopena pale i ka novel coronavirus ka mea nui e pili ana i nā masks pale disposable a me nā masks N95.ʻO ka mea kānana nui no kēia mau masks ʻelua he maikaʻi loa, ka lole kānana electrostatic - ka lole i ulana ʻole ʻia.Hoʻoheheʻe ʻia ka lole i ulana ʻole ʻia i hana ʻia me ka polypropylene, he ʻano lole fiber electrostatic ultrafine, hiki ke hopu i ka lepo.
ʻO nā kulu e loa'a ana ka ma'i ma'i ma'i ma'i ma'i ma'i ma kahi kokoke i ka lole i ulana 'ole e hooheheeia e lilo i electrostatic adsorption ma ka ili o ka lole i ulana 'ole, 'a'ole hiki ke hele, 'o ia ke kumu o keia. mea hoʻokaʻawale kino bacteria.Ma hope o ka hopu ʻia ʻana o ka lepo e ka ultrafine electrostatic fiber, paʻakikī loa ke hoʻokaʻawale ʻia e ka hoʻomaʻemaʻe, a ʻo ka holoi ʻana e hoʻopau i ka hiki ke hōʻiliʻili lepo electrostatic, no laila hiki ke hoʻohana ʻia kēia mask i hoʻokahi wale nō.
Hana ʻia nā masks pale i hoʻokuʻu ʻia i ʻekolu ʻāpana o ka lole i ulana ʻole ʻia.ʻO ka mea spunbonded ʻaʻole i ulana ʻia + melt-blown non-woven fabric + spunbonded non-woven fabric.
ʻAʻole i kuhikuhi ʻia kekahi mau papa masks ma ke kūlana aupuni GB/T 32610 no nā masks.No nā masks lapaʻau, pono e loaʻa ma ka liʻiliʻi he 3 papa, i kapa ʻia ʻo SMS (2 papa o S a me 1 papa o M).
ʻO ka helu kiʻekiʻe loa o nā papa ma Kina i kēia manawa he 5 papa, i kapa ʻia ʻo SMMMS (2 papa o S a me 3 papa o M).Aia ka S i ka papa Spunbond (Spunbond), ʻano mānoanoa kona anawaena fiber, ma kahi o 20 microns (μm), ʻo ka hana nui o nā ʻāpana 2 o S Spunbond ke kākoʻo i ke ʻano o ka lole i ulana ʻole ʻia, a ʻaʻohe hopena nui i ka pale.ʻO ka mea nui i loko o ka mask ʻO ia ka papa pale a i ʻole ka papa Meltblown M (Meltblown).
ʻOi aku ka maikaʻi o ke anawaena fiber o ka papa Meltblown, ma kahi o 2 microns (μm), he hana koʻikoʻi ia i ka pale ʻana i ka bacteria a me ke koko mai ke komo ʻana. i loko.Inā ʻoi aku ka nui o nā papa wili S, paʻakikī ka mask, a ʻoi aku ka nui o ka ʻōpala M, paʻakikī ka hanu, no laila mai ka maʻalahi o ka hanu ʻana a hiki i ka loiloi i ka hopena o nā masks kaʻawale, ʻoi aku ka hanu. paʻakikī, ʻoi aku ka maikaʻi o ka hopena o ka pale ʻana, akā, inā ʻo ka M layer i ke kiʻiʻoniʻoni, ʻaʻole ia e hanu manuahi, ua ʻoki ʻia ka maʻi, akā ʻaʻole hiki i nā kānaka ke hanu.ʻO ka N95 he mask 5-layer i hana ʻia mai ka polypropylene nonwoven SMMMS e kānana a hiki i ka 95% o nā ʻāpana maikaʻi.
No laila, ua ʻike mākou ʻo nā masks hiki ke hoʻokaʻawale maoli i ka maʻi maʻi pono e hana ʻia i nā mea kikoʻī, a ʻaʻole kūpono nā mea āpau no nā masks.
ʻO ka mea hope loa, manaʻolana mākou ORIENTMED hiki i nā mea āpau ke mālama iā ʻoe iho me ka palekana a me ke olakino.
