He aha nā mea maka nui no ka lole i ulana ʻole ʻia

ʻO ka polypropylene kekahi o nā mea nuimea makano nā lole i ulanaʻoleʻia, hiki ke hāʻawi i nā lole i ulanaʻoleʻia me nā mea kino maikaʻi.

He aha ka lole i ulana ʻole ʻia

ʻO ka lole ʻaʻole i ulana ʻia he hanauna hou o nā mea pili i ke kaiapuni e hui pū ai i nā fibers a i ʻole nā ​​ʻāpana pōkole granular ma o nā ʻano kemika, mechanical, a i ʻole nā ​​​​mea hana kemika, me ka ʻole o ka hoʻonohonoho ʻana i nā fibers ma ke ʻano textile.

No ke aha e hoʻohana ai i ka polypropylene

ʻO ka polypropylene kekahi o nā mea maʻamau maʻamau i ka hana ʻana i nā lole i ulana ʻole ʻia, ma muli o kēia mau kumu:

1. ʻO ka polypropylene ka pale lole maikaʻi a me ka paʻakikī, hiki ke hoʻonui i ka ikaika a me ka lōʻihi o nā lole i ulanaʻoleʻia;

2. He mea maʻalahi ka polypropylene i ka hana a me ke ʻano, e maʻalahi ka hana ʻana o nā lole i ulana ʻole ʻia;

3. Hoʻoheheʻe ka polypropylene i nā wela kiʻekiʻe a hiki ke hāʻawi i ka paʻa maikaʻi no nā lole i ulana ʻole ʻia.

ʻO nā hiʻohiʻona o nā mea polypropylene kūikawā no nā lole meltblown

ʻO ka mea hoʻoheheʻe polypropylene kūikawā PP he polymer thermoplastic āpau, nona nā hiʻohiʻona o ka ikaika kiʻekiʻe, ka insulation maikaʻi, ka haʻahaʻa wai haʻahaʻa, ka wela wela deformation kiʻekiʻe, ka haʻahaʻa haʻahaʻa, ka crystallinity kiʻekiʻe, a me ka kahe kahe maikaʻi; I ka manawa like, loaʻa iā ia ke kūpaʻa solvent maikaʻi, ka pale ʻaila, ka waika nāwaliwali a me ke kūpaʻa alkali, a he maʻalahi a maʻalahi hoʻi e loaʻa, no laila ua hoʻohana nui ʻia i ka māla fiber.

Kaʻina hana no nā mea polypropylene kūikawā no ka lole meltblown

Ma muli o ke ʻano o ka ʻenehana hoʻoheheʻe ʻia, pono nā mea waiwai PP i hoʻohana ʻia ma ke ʻano he mea kūikawā no ka hoʻoheheʻe ʻana i nā lole nonwoven e hoʻokō i kēia mau koi:

(1) Pono e oi aku ka helu helu hehee kiʻekiʻe ma mua o 400g/10min.

(2) Narrow relative molecular weight distribution (MWD).

(3) Haʻahaʻa lehu maʻiʻo, haʻahaʻa hehee ai index o meltblown maka mea, kiʻekiʻe viscosity o ka heheʻe, e koi ana i ka extruder e hoʻolako i oi aku kaomi e smoothly extrude ia mai ka nozzle puka, e koi nui ikehu hoʻohana a me ka hoʻoheheʻe 'ana i ka mea hooheheeia i ka oi puʻe; A ʻaʻole hiki ke hoʻomaloʻo piha ʻia a hoʻomaʻemaʻe ʻia ka heheʻe ma hope o ka hoʻokuʻu ʻia ʻana mai ka lua wili, ʻaʻole hiki ke hana i nā fibers ultrafine.

No laila, ʻo PP wale nō nā mea waiwai me ka helu hoʻoheheʻe kiʻekiʻe e hiki ke hoʻokō i nā koi o ka ʻenehana hoʻoheheʻe ʻia, hoʻopuka i nā lole nonwoven ultrafine fiber kūpono, a hoʻemi i ka hoʻohana ʻana i ka ikehu. He hopena koʻikoʻi ka hāʻawi ʻana i ka paona molekala pili i nā waiwai, ka hana ʻana, a me ka hoʻohana ʻana o ka hoʻoheheʻe PP. No ka hana ʻana i nā lole hoʻoheheʻe ʻole i ulana ʻia, inā ʻoi aku ka laulā o ka puʻunaue ʻana o ke kaumaha molecular a loaʻa kahi kiʻekiʻe o ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa PP, e ʻoi aku ka koʻikoʻi o ke koʻikoʻi o PP.

ʻO ke kuleana o ka polypropylene i nā lole i ulana ʻole ʻia

1. Hoʻonui i ka ikaika a me ka lōʻihi o nā lole i ulana ʻole ʻia

Ma muli o kona kūpaʻa maikaʻi a me ka paʻakikī, hiki i ka hoʻohui ʻana i ka polypropylene ke hoʻomaikaʻi i ka ikaika a me ka lōʻihi o nā lole i ulana ʻole ʻia, e ʻoi aku ka lōʻihi a me ke kūpaʻa.

2. E hoʻomaikaʻi i ka hana kānana o nā lole i ulana ʻole ʻia

ʻO ka polypropylene kahi mea microporous hiki ke kānana i nā mea liʻiliʻi ma o ka hoʻomalu ʻana i kona nui pore i ka wā o ka hana ʻana i nā lole i ulana ʻole ʻia. No laila, hiki i ka polypropylene ke hōʻike i ka hana kānana maikaʻi loa i nā lole i ulana ʻole ʻia.

3. E hana i ka lole i ulana ʻole ʻia i mea ʻoi aku ka paʻa

Hoʻoheheʻe ʻia ka polypropylene i nā wela kiʻekiʻe a hāʻawi i ka hoʻopaʻa maikaʻi ʻana no nā lole i ulana ʻole ʻia, e hana ana i kahi paʻa paʻa ma waena o nā fibers a me ka hana ʻana i nā lole i ulana ʻole ʻia i ʻoi aku ka paʻa a paʻa.

Ka hopena

I ka hōʻuluʻulu ʻana, ʻo ka polypropylene, ʻo ia kekahi o nā mea waiwai nui no nā lole i ulana ʻole ʻia, hiki ke hāʻawi i nā lole i ulana ʻole ʻia me nā waiwai kino maikaʻi loa a ke pāʻani nei i kahi hana koʻikoʻi i ka hana ʻana i nā lole i ulana ʻole ʻia.
