ʻO ka lole ʻaʻole i ulana ʻia e ka nila PLA: kahi mea pili i ka kaiapuni

I ka ʻimi ʻana i nā mea ʻoi aku ka hoʻomau ʻana a me ke kaiapuni,PLA nā mea i ulana ʻole ʻiaua puka mai ma ke ʻano he koho hoʻohiki. Hana ʻia ka mea hou mai ka polylactic acid (PLA), kahi waiwai biodegradable, hiki ke hoʻololi hou ʻia mai nā kumu mea kanu e like me ka starch kulina a i ʻole ke kō. ʻO ke kaʻina hana needling e pili ana i nā fibers interlocking mechanically e hana i kahi lole nonwoven ikaika a paʻa, i kūpono ia no nā ʻano hana like ʻole.

ʻO kekahi o nā pono kaiapuni nui o PLA needlepunched nonwovens ʻo ia kona biodegradability. ʻAʻole like me nā mea hana ʻaila maʻamau, hoʻoheheʻe maoli nā PLA nonwovens, hoʻomaha i nā pae ʻāina a hōʻemi i ka hopena o ke kaiapuni. He koho maikaʻi kēia no nā ʻoihana e ʻimi nei e hōʻemi i kā lākou kapuaʻi kalapona a hāpai i nā hana hoʻomau.

Eia hou, ka hana ana oPLA nā mea i ulana ʻole ʻiahoemi i ka ikehu a emi mai ke kinoea kinoea ma mua o na mea synthetic ma'amau. Kūlike kēia me ka piʻi nui ʻana o ka noi no nā mea ʻokoʻa e pili ana i ke kaiapuni e ʻoi aku ka nui o ka mālama ʻana i ke kaiapuni a me ka pono waiwai.

ʻO ka versatility o PLA needlepunched nonwovens kōkua pū ia e pili i ke kaiapuni. Hiki ke hoʻohana ʻia i loko o nā noi like ʻole me ka hoʻopili, textiles, filtration a me geotextiles, e hāʻawi ana i kahi ʻano hoʻomau i nā mea kuʻuna ma kēia mau wahi. ʻO kona ikaika, ka hanu a me ka biodegradability i mea kūpono no nā ʻoihana a me nā mea kūʻai aku e ʻimi nei e hana i nā hoʻoholo pili kaiaola.

Ma kahi o nā pono kaiapuni, hāʻawi pū nā PLA needlepunched nonwovens i nā pono hana. Loaʻa iā ia ka hoʻokele wai maikaʻi, ka pale ʻana o UV a me nā waiwai insulation thermal, e hana ia i mea kūpono a hilinaʻi hoʻi no nā ʻano noi.

Ke hoʻomau nei ka ulu ʻana o ka noi no nā mea hoʻomau, ʻo PLA needlepunched nonwovens e kū nei ma ke ʻano he hopena kūpono e hoʻokō i nā pahuhopu kaiapuni. ʻO kona biodegradability, ka ikehu a me ka versatility e lilo ia i koho maikaʻi loa no nā ʻoihana a me nā mea kūʻai aku e ʻimi nei e hōʻemi i ko lākou hopena kaiapuni a apo i ka wā e hiki mai ana. Ma ka hoʻokomo ʻana i nā PLA needlepunched nonwovens i loko o nā huahana like ʻole a me nā noi, hiki iā mākou ke hāʻawi i kahi honua olakino ʻoiai e hoʻokō ana i nā pono o ka nohona pili honua i kēia mau lā.
