ʻO ka ʻokoʻa ma waena o spunbond a me meltblown

ʻO Spunbond a me ka hoʻoheheʻe ʻana he ʻelua mau kaʻina hana lole ʻaʻole i ulana ʻia, he ʻokoʻa koʻikoʻi i nā mea maka, nā ʻano hana, ka hana huahana, a me nā kahua noi.

ʻO ke kumu o ka spunbond a me ka hehee i puhi ʻia

ʻO Spunbond kahi lole i ulana ʻole ʻia i hana ʻia e ka hoʻoheheʻe ʻana i nā mea polymer i loko o ke ʻano i hoʻoheheʻe ʻia, e pīpī i ka mea hoʻoheheʻe ʻia ma luna o ka rotor a i ʻole ka nozzle, e huki ana i lalo i ke ʻano hoʻoheheʻe ʻia a hoʻopaʻa koke iā ia e hana i kahi mea fibrous, a laila e hoʻopili a hoʻopaʻa i nā fibers ma o ka mesh a i ʻole electrostatics wili. ʻO ke kumumanaʻo e hoʻokuʻu i ka polymer hehee ma o kahi extruder, a laila e hele i nā kaʻina hana like ʻole e like me ka hoʻoluʻu ʻana, ka hoʻopololei ʻana, a me ka hoʻolōʻihi ʻana i ke kuhikuhi, i ka hopena i ka hana ʻana i kahi lole i ulana ʻole ʻia.

ʻO Meltblown, ma ka ʻaoʻao ʻē aʻe, ʻo ia ke kaʻina o ka hoʻokuʻu ʻana i nā mea polymer mai kahi moku i hoʻoheheʻe ʻia ma o ka nozzle kiʻekiʻe. Ma muli o ka hopena a me ka ʻoluʻolu o ka ea holo wikiwiki, hoʻopaʻa koke nā mea polymer i nā mea filamentous a lana i ka lewa, a laila e hana maoli ʻia a pulu paha e hana i kahi pūnaewele fiber maikaʻi o ka lole ʻaʻole i ulana ʻia. ʻO ke kumumanaʻo, ʻo ia ka pīpī ʻana i nā mea polymer hoʻoheheʻe kiʻekiʻe, hoʻopololei iā lākou i loko o nā fibers maikaʻi ma o ka holo wikiwiki ʻana o ka ea, a hoʻopaʻa koke i nā huahana oʻo i ka lewa, e hana ana i kahi papa o nā mea lole lole ʻole.

Nā mea maka ʻokoʻa

Hoʻohana maʻamau nā lole spunbonded non-woven e like me ka polypropylene (PP) a i ʻole polyester (PET) ma ke ʻano he kumu, ʻoiai ka hoʻoheheʻe ʻana i nā lole i ulana ʻole ʻia e hoʻohana i nā mea polymer i loko o kahi moku i hoʻoheheʻe ʻia, e like me ka polypropylene (PP) a i ʻole polyacrylonitrile (PAN). Pono ʻo Spunbonding e loaʻa iā PP kahi MF o 20-40g / min, ʻoiai ʻo ka hoʻoheheʻe ʻana he 400-1200g / min.

Hoʻohālikelike ma waena o nā pulupulu hoʻoheheʻe ʻia a me nā fibers spunbond

A. Ka lōʻihi o ka fiber – spunbond e like me ke filament, hehee i puhi ʻia e like me ka fiber pōkole

B. Ka ikaika o ka fiber: Spunbonded fiber strength>Melted fiber strength

C. Fiber fineness: ʻOi aku ka maikaʻi o ka fiber hehee ma mua o ka fiber spunbond

Nāʻano hana hana likeʻole

ʻO ka hana ʻana o ka lole spunbond non-woven e komo pū ana me ka hoʻoheheʻe ʻana i nā fiber kemikala i nā wela kiʻekiʻe, e huki ana iā lākou, a laila e hana i kahi ʻano pūnaewele fiber ma o ka hoʻoluʻu ʻana a me ke kau ʻana; ʻO ka lole i ulana ʻole ʻia i hoʻoheheʻe ʻia he kaʻina o ka hoʻoheheʻe ʻana i nā mea polymer i hoʻoheheʻe ʻia i ka lewa ma o ka nozzle kiʻekiʻe, hoʻomaʻalili wikiwiki a hoʻolōʻihi iā lākou i loko o nā fibers maikaʻi ma lalo o ka hana o ka holo ʻana o ka ea kiʻekiʻe.

ʻO kekahi o nā hiʻohiʻona o nā lole i ulana ʻole ʻia i hoʻoheheʻe ʻia ʻo ia ka liʻiliʻi o ka fiber fineness, ʻoi aku ka liʻiliʻi ma mua o 10nm (micrometers), a ʻo ka hapa nui o nā fibers he fineness o 1-4 rm.

ʻAʻole hiki ke kaulike nā mana like ʻole ma ka laina wili holoʻokoʻa mai ka nozzle hoʻoheheʻe ʻia a hiki i ka mea e loaʻa ai ke kaulike (no ka hoʻololi ʻana o ka ikaika tensile o ke kiʻekiʻe-mehana a me ka wikiwiki o ka ea, ka wikiwiki a me ka mahana o ka ea hoʻoluʻu, a me nā mea ʻē aʻe), ka hopena i ka fineness fiber uneven.

ʻOi aku ka maikaʻi o ka like ʻana o ke anawaena o ka fiber i loko o ka spunbond nonwoven fabric mesh ma mua o ko ka pulupulu pulupulu, no ka mea, ma ke kaʻina spunbond, paʻa nā kūlana wili, a he liʻiliʻi nā loli i ka hoʻololi ʻana a me nā kūlana hoʻoluʻu.

ʻOkoʻa ke kahe ʻana o ka milo. He 50-80 ℃ ke kiʻekiʻe o ka milo hoʻoheheʻe ʻana ma mua o ka milo spunbond.

ʻOkoʻa ka māmā holo o nā fiber. ʻAi milo 6000m/min, hehee puhi 30Km/min.

Ua ʻō aku ka mōʻī i kona mamao akā ʻaʻole hiki iā ia ke kāohi. Spunbound 2-4m, hui ʻia 10-30cm.

ʻOkoʻa nā kūlana hoʻoluʻu a me ka huki. Huki ʻia nā ʻili o Spinnbond me ka ea anu maikaʻi/negative ma 16 ℃, ʻoiai e puhi ʻia nā fuse me ka ea wela maikaʻi/negative kokoke i 200 ℃.

Hana huahana like ʻole

ʻO nā lole spunbonded non-woven maʻamau ka ikaika haʻihaʻi kiʻekiʻe a me ka elongation, akā ʻilihune paha ke ʻano a me ke ʻano like ʻole o ka fiber mesh, e kūpono ana i nā pono o nā huahana e like me nā ʻeke kūʻai; ʻO ka lole i ulana ʻole ʻia i hoʻoheheʻe ʻia he hanu maikaʻi, kānana, ʻaʻahu kūʻē, a me nā waiwai anti-static, akā hiki ke loaʻa i ka lima maikaʻi ʻole a me ka ikaika, a hiki ke hoʻohana ʻia e hana i nā mea lapaʻau a me nā huahana ʻē aʻe.

Nā kahua noi like ʻole

Hoʻohana nui ʻia nā lole spunbonded non-woven i ka lāʻau lapaʻau, ka lole, ka home, ka ʻoihana a me nā ʻano ʻē aʻe, e like me nā masks, nā ʻokiʻoki, nā uhi sofa, nā pale, etc. Hoʻohana nui ʻia ka melt blown non-woven fabric i ka lāʻau lapaʻau, olakino, pale, mālama kaiapuni a me nā ʻano ʻē aʻe, e like me nā masks kiʻekiʻe, nā lole pale, nā kānana, etc.

Ka hopena

ʻO ka lole i ulana ʻole ʻia i hoʻoheheʻe ʻia a me ka lole spunbond ʻaʻole i ulana ʻia ʻelua mau mea lole i ulana ʻole ʻia me nā kaʻina hana hana a me nā ʻano. Ma keʻano o ka noi a me ke kohoʻana, pono e noʻonoʻo pono i nā pono maoli a me nā hiʻohiʻona hoʻohana, a koho i ka mea kūponoʻole i ulanaʻia.
