Mai ka laha ʻana o ka maʻi Coronavirus hou,nā pale makaua lilo i mea pale pono ʻole no nā kānaka. I ka manawa koke, ua lilo nā pale maka i mea kakaikahi ma ka mākeke. A ʻo ka hana ʻana o nā pale maka o nā mea maka i hoʻoheheʻe ʻia i nā lole nonwoven, ma muli o ka nui o ka hakahaka, ua lilo i mea wela i loko o ka pūnaewele, akā he wahi paʻakikī hoʻi.
Ma mua o ke ahulau, he kakaikahi ka poʻe i ʻike. Ma hope o ke ahulau, ua ʻike lākou he mea kūikawā ia no ka hana ʻana i nā pale maka.
He aha ka ʻenehana o ka meltblown nonwoven?
Eia ka mea aʻeulana ʻole i hoʻoheheʻe ʻiamea hana lole e hoʻomaopopo:
ʻAno hoʻoheheʻe ʻana: lole kānana polypropylene fiber ultrafine, no ka mea aia i loko o ka ʻoihana lole, he lole ulana ʻole ia, ʻo ke kaʻina hana he ʻano hoʻoheheʻe ʻana, ka inoa maʻamau: lole ulana ʻole i ulana ʻia me ka hoʻoheheʻe ʻana.
Nui nā ʻano lole ulana ʻole meltblown me nā noi ākea. ʻO nā lole ulana ʻole melt-spray maoli i hoʻohana ʻia i ka hana mask ʻo ia nā lole kānana polypropylene fiber ultrafine i ʻōlelo ʻia ma luna, e hoʻokō ana i nā koi maikaʻi o nā masks.
No laila he aha nā koi no ka lole nonwoven meltblown i hoʻohana ʻia ma ke ʻano he mask?
1. Mea Hana: kūlike me ke kūlana maʻemaʻe;
2. Ka permeability ea (ka pono o ka transmittance): ma luna o 95%;
3. Ke kū'ē: ma lalo o 40Pa;
4. Maikaʻi ka hydrophobicity o nā mea.
No laila, ʻo nā kikoʻī loea o ka lole kānana polypropylene ultrafine e hoʻokō i nā koi hana o nā masks. Inā hana ʻia ka mask me ka lole ulana ʻole i hoʻoheheʻe ʻia me ka hoʻoheheʻe ʻia, ʻaʻole hiki iā ia ke hoʻokō i nā koi maikaʻi.
No ke aha e hana ʻia ai ka pale maka me ka "melt spray ultrafine polypropylene fiber filter cloth"?
No ka mea, ke piʻi nei mai ka qualitative o ka mea, ʻo ke ʻano kumu o ka polypropylene fiber, ʻo ia hoʻi e kūlike me ke kūlana olakino, ʻawaʻawa, ʻono ʻole, hoʻopailua ka hana wai he mea maikaʻi ia e kali ai no kahi ʻano.
Mai ke kaʻina hana ʻana, ua hoʻohana ʻia ke ʻano pīpī hoʻoheheʻe, no ka mea, ʻo ke kahe o ka ʻenehana pīpī hoʻoheheʻe: ʻo ia hoʻi ma o: ka hoʻoheheʻe ʻana - ka jet - ka draft e hiki ai i ke kiʻekiʻe o ka fiber ultrafine, a ua hoʻokumu ʻia ka lole ulana e kona wela ponoʻī, no laila maikaʻi ka permeability ea a me ka pono kānana kiʻekiʻe. He paʻakikī ke hoʻokō i nā kaʻina hana ʻē aʻe.
ʻO ka mea i luna aʻe nei he hoʻolauna pōkole ia olole ulana ʻole i hoʻoheheʻe ʻia. Manaʻolana wau e makemake ʻoe. He mea hana ʻoihana mākou o ka lole nonwoven meltblown.Inā pono ʻoe e kūʻai, e ʻoluʻolu e kelepona koke mai iā mākou. Mai kānalua ~ hiki iā mākou ke hoʻouna aku i nā laʻana iā ʻoe no ka manuahi ~
