Ke puka maoli mai nei ka lole i hoʻoheheʻe ʻia! E hahai kākou i kamea hana lole i hoʻoheheʻe ʻiae hoʻomaopopo:
Ua hoʻomaka ka ʻenehana lole Meltblown i nā makahiki 1950, i ka wā i hoʻomohala ai ʻo ʻAmelika Hui Pū ʻIa i nā mea kānana ultrafine e hōʻiliʻili i nā ʻāpana radioactive i ka lewa o luna, a laila hana pololei i ka ʻenehana lole non-woven ma lalo o ka hana o ka mahana a me ke kahe o ka ea.
Hoʻohui kēia ʻenehana i ka ʻenehana hana mea polymer o ka ʻoihana kemika a me ka ʻenehana hana mea ulana ʻole o ka ʻoihana textile, e hana ana i kahi ʻenehana hou ma ke kahua o ka ʻepekema mea e hana i nā mea kānana kemika hou a me ka maikaʻi.
ʻO ka mea maka o ka lole pīpī hoʻoheheʻe he polypropylene me ka helu hoʻoheheʻe kiʻekiʻe.
ʻO ke kiʻekiʻe o ka helu hoʻoheheʻe o ka polypropylene, ʻoi aku ka maikaʻi o ka fiber, a ʻoi aku ka maikaʻi o ke kānana ʻana o ka lole i pīpī ʻia i ka hoʻoheheʻe ʻia.
He polymer ka Polypropylene i hoʻokumu ʻia e ka hopena hoʻohui o ka propylene. He mea waxy keʻokeʻo, moakāka a māmā hoʻi ke ʻano. ʻO ka nui o ka density he 0.89 ~ 0.91g/cm3, hiki ke lapalapa, he 165 ℃ ka heheʻe ʻana, palupalu ma 155 ℃, a ʻo ka pae mahana he -30 ~ 140 ℃.
Ma lalo o 80 ℃ hiki ke kū'ē i ka waikawa, alkali, ka hopena pa'akai a me nā ʻano mea ho'ohehe'e organik like ʻole, hiki ke decomposed ma lalo o ke ana wela a me ka oxidation. Ho'ohana nui'ia ka Polypropylene i nā lole, nā pākeke a me nā huahana fiber'ē a'e, nā lako lapa'au, nā ka'a, nā paikikala, nā'āpana'ē a'e, nā pipeline halihali, nā pahu kemika a me nā hana'ē a'e, ho'ohana'ia ho'i i ka mea'ai, ka ho'opili lā'au lapa'au.
He hale hana pīpī hoʻoheheʻe mākou, ʻo nā huahana:KF94 i hoʻoheheʻe ʻia,BFE99 i hoʻoheheʻe ʻia,puhi ʻia ka pp heheʻe,n95 i puhi ʻia me ka heheʻe;Mai kānalua e hoʻokaʻaʻike mai iā mākou no ka ʻōlelo hou loa ~
