He aha ka ʻokoʻa ma waena o spunbond a me meltblown

ʻO ka spunbond a me ka meltblown nā ʻenehana kaʻina hana no ka hana ʻana i nā lole i ulana ʻole ʻia me ka hoʻohana ʻana i nā polymers ma ke ʻano he kumu, a ʻo kā lākou ʻokoʻa nui aia i ka mokuʻāina a me nā ʻano hana o nā polymers.

ʻO ke kumu o ka spunbond a me ka meltblown

ʻO Spunbond kahi lole i ulana ʻole ʻia i hana ʻia e ka hoʻoheheʻe ʻana i nā mea polymer i loko o ke ʻano hoʻoheheʻe ʻia, e pīpī i ka mea hoʻoheheʻe ʻia ma luna o ka rotor a i ʻole ka nozzle, e hohola a paʻa koke i ka moku i hoʻoheheʻe ʻia e hana i nā mea fibrous, a laila hoʻopili a hoʻopaʻa ʻia nā fiber ma o nā kāʻei mesh a i ʻole ka wili electrostatic. ʻO ke kumu o ka hoʻoheheʻe ʻana i ka polymer hehee ma o ka extruder, a laila hele i nā kaʻina hana like ʻole e like me ka hoʻoluʻu ʻana, ka hoʻolōʻihi ʻana, a me ka hoʻolōʻihi ʻana i ke kuhikuhi a hiki i ka loaʻa ʻana o kahi lole i ulana ʻole ʻia.

ʻO Meltblown kahi kaʻina o ka pīpī ʻana i nā mea polymer mai kahi moku i hoʻoheheʻe ʻia ma o nā nozzles kiʻekiʻe. Ma muli o ka hopena a me ka ʻoluʻolu o ka ea holo wikiwiki, hoʻopaʻa koke nā mea polymer i nā filament a hoʻopuehu i ka lewa. A laila, ma o ka pae ʻana maoli a i ʻole ka hoʻomaʻamaʻa ʻana i ka pulu, ua hoʻokumu ʻia kahi lole fiber mesh non-woven. ʻO ke kumumanaʻo, ʻo ia ka pīpī ʻana i nā mea polymer hoʻoheheʻe kiʻekiʻe, e hohola iā lākou i loko o nā fibers maikaʻi ma o ka holo ʻana o ka ea wikiwiki, a hoʻopaʻa koke iā lākou i nā huahana oʻo i ka lewa, e hana ana i kahi papa o nā mea lole lole ʻole.

ʻO ka ʻokoʻa ma waena o ka lole i ulana ʻole ʻia a me ka lole spunbond non-woven

Nāʻano hana hana likeʻole

Hana ʻia ka lole hoʻoheheʻe ʻole i ulana ʻia ma o ka ʻenehana hoʻoheheʻe ʻana, kahi e hoʻoheheʻe ʻia ai nā mea polymer a hoʻoheheʻe ʻia ma luna o kahi template, ʻoiai ʻo ka spunbond non-woven fabric e hana ʻia i lole ʻaʻole i ulana ʻia ma o ka hoʻoheheʻe ʻana i nā fiber kemika i nā fiber paʻa ma o ka hana solvent a i ʻole ka wela kiʻekiʻe, a laila e hana ʻia i ka lole non-woven ma o ka hana mechanical a i ʻole kemika.

Nā ʻenehana kaʻina hana like ʻole

(1) Heʻokoʻa nā koi no nā mea maka. Pono ʻo Spunbond i kahi MFI o 20-40g / min no PP, aʻo ka hoʻoheheʻe ʻana e pono ai 400-1200g / min.

(2) He okoa ka wela o ka wili. He 50-80 ℃ ke kiʻekiʻe o ka milo hoʻoheheʻe ʻana ma mua o ka milo spunbond.

(3) ʻOkoʻa ka māmā holo o nā fiber. Spunbond 6000m/min, hehee puhi 30km/min.

(4) ʻO ka pōmaikaʻi, ʻaʻole maʻalahi ka mamao. Spunbond 2-4m, hehee puhi 10-30cm.

(5) He ʻokoʻa nā kūlana hoʻoluʻu a hoʻolōʻihi. Hoʻohana ʻia nā fibers Spunbond me ka hoʻohana ʻana i ka ea anuanu 16 ℃ me ke kaomi maikaʻi/negative, ʻoiai e puhi ʻia nā fuse me kahi noho wela me kahi mahana kokoke i 200 ℃.

Nā ʻokoʻa o nā waiwai kino

Nā lole Spunbondʻoi aku ka ʻoi aʻe o ka ikaika haʻihaʻi a me ka elongation ma mua o nā lole meltblown, e hopena i nā kumukūʻai haʻahaʻa. Akā ʻaʻole maikaʻi ka manaʻo o ka lima a me ka fiber mesh uniformity.

ʻO ka lole Meltblown he fluffy a palupalu, me ka maikaʻi kānana kiʻekiʻe, haʻahaʻa haʻahaʻa, a me ka hana pale maikaʻi. Akā, haʻahaʻa ka ikaika a me ka maikaʻi ʻole o ka ʻaʻahu.

Hoʻohālikelike i nā ʻano hana

ʻO kekahi o nā hiʻohiʻona o nā lole i hoʻoheheʻe ʻole ʻia, ʻo ia ka liʻiliʻi o ka fiber fineness, ʻoi aku ka liʻiliʻi ma mua o 10um (micrometers), me ka hapa nui o nā fibers he fineness ma waena o 1-4um. ʻO nā mana like ʻole ma ka laina wili holoʻokoʻa mai ka nozzle o ka meltblown make a hiki i ka mea hoʻokipa ʻaʻole hiki ke mālama i ke kaulike (e like me ka hoʻololi ʻana o ka ikaika o ka ea kiʻekiʻe a me ka wikiwiki o ka ea, ka wikiwiki a me ka mahana o ka ea hoʻoheheʻe, etc.

ʻOi aku ka maikaʻi o ka like ʻana o ke anawaena o ka fiber i ka spunbond nonwoven fabric web ma mua o ka meltblown fibers, no ka mea, i ke kaʻina spunbond, ʻoi aku ka paʻa o ke kaʻina hana wili, a ʻoi aku ka maikaʻi o ke kau ʻana a me ke anuanu.

Hoʻohālikelike o ka Crystallization a me ka Orientation Degree

ʻOi aku ka liʻiliʻi o ka crystallinity a me ka hoʻonohonoho ʻana o nā fiber i hoʻoheheʻe ʻia ma mua o nā fibers spunbond. No laila, ʻilihune ka ikaika o nā pulupulu heheʻe, a ʻilihune hoʻi ka ikaika o ka pūnaewele fiber. Ma muli o ka maikaʻi ʻole o ka pulupulu o nā lole i ulana ʻole ʻia, ʻo ka hoʻohana maoli ʻana i nā lole i hoʻoheheʻe ʻia i ka hoʻoheheʻe ʻole ʻia e hilinaʻi nui ʻia i nā ʻano o kā lākou ultrafine fibers.

Hoʻohālikelike ma waena o nā fibers spun melt a me nā fibers spunbond

A、 Fiber lōʻihi - spunbond he loloa lōʻihi, meltblown mea pōkole

B、 ​​Ka ikaika o ka pulupulu - ka ikaika o ka pulupulu spunbond> ka ikaika o ka pulupulu hoohehee

ʻOi aku ka maikaʻi o ka fiber - ʻoi aku ka maikaʻi o nā fiber Meltblown ma mua o nā fibers spunbond

Nā hiʻohiʻona noiʻi like ʻole

ʻOkoʻa nō hoʻi nā kahua noi o spunbond a me meltblown. ʻO ka mea maʻamau, hoʻohana nuiʻia nā lole spunbond no nā mea maʻemaʻe a me nāʻoihanaʻoihana, e like me nā napkins sanitary, masks, kānana lole, a me nā mea'ē aʻe. Ma muli o ko lākou ʻano wiwi a paʻa, ʻoi aku ka maikaʻi o ka kānana ʻana i nā lole meltblown a hiki ke kānana maikaʻi i nā ʻāpana maikaʻi a me nā ʻāpana virus.

Hoʻohālikelike kumu kūʻai ma waena o spunbond a me meltblown

Aia kahi ʻokoʻa nui i nā kumukūʻai hana ma waena o spunbond a me meltblown. He kiʻekiʻe ke kumu kūʻai o ka spunbond no ka mea e pono ai ka nui o ka ikehu a me nā kumukūʻai lako. I ka manawa like, ma muli o ka mānoanoa o nā fibers, ʻoi aku ka paʻakikī o nā lole i hana ʻia e spunbond a ʻoi aku ka paʻakikī o ka ʻae ʻia e ka mākeke.

ʻO ka mea ʻē aʻe, ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka meltblown no ka mea hiki ke hōʻemi i nā kumukūʻai ma o ka hana nui a me ka automation. Ma ka manawa like, ma muli o ka ʻoi aku ka maikaʻi o nā fibers, ʻoi aku ka palupalu a me ka maikaʻi o nā lole meltblown, hiki ke hoʻokō maikaʻi i ka noi mākeke.
