Pono ke kānana ʻia ka PET PA PP polymer kiʻekiʻe i hoʻoheheʻe ʻia ma mua o ka wili ʻana o ka fiber kemikal e wehe i ka haumia a me nā ʻāpana gel i hoʻokomo ʻia i loko o ka hehee e pale ai i ka hoʻopili ʻana o ka lua spinneret, e hoʻomaikaʻi i ka maikaʻi o ka fiber filament PET PA, e like me nā yarns POY FDY. ;i ka wā e kahe ai ka polimer hehee ma ka ʻāpana pale wili, hoʻokumu ʻia ke kūʻē ʻana, no laila e hoʻoheheʻe ka hoʻoheheʻe ʻana i ka wela, piʻi ka mahana, a hoʻomaikaʻi ʻia nā waiwai rheological o ka heheʻe.I ka manawa like, ua hui pū ʻia ka hoʻoheheʻe ʻana e pale i nā ʻokoʻa viscosity ma waena o nā melts;puunaue like ia ka hehee i kela me keia puka liilii o ka spinneret;me ka piʻi ʻana o ka manawa hoʻohana ʻana i ka kānana puʻupuʻu milo, e hoʻonui ʻia nā haumia i loko o ka papa kānana mesh pack, a e piʻi mālie ke kaomi o ka ʻaha.ʻO ka wikiwiki o ka piʻi ʻana o ka puʻe wikiwiki, a pōkole ke ola lawelawe o ka ʻaha.Ke piʻi ka hui i kahi kaomi, pono ia e hoʻololi i ka hui i ka manawa, inā ʻaʻole, ua ʻoki ʻia ka mīkini mika, a i ʻole ke ʻano o ka spinneret, a i ʻole ka leakage.
He mea koʻikoʻi loa ke koho ʻana i nā ʻāpana kānana kūpono no ka wili fiber synthetic, a he mea koʻikoʻi ka media kānana pono.Ma ke kaʻina o ka hoʻomohala ʻana i ka milo, ʻo ia hoʻi ke kaʻina o ka loaʻa ʻana o kahi ʻano kānana ʻāwī maikaʻi.Nui nā mea kānana i ʻike ʻia e pili ana i ke one kai, nā kohu metala, nā peʻa aniani, nā papa metala porous i hoʻopaʻa ʻia, a me nā ʻāpana metala like ʻole.
Ma waho aʻe o ke kumukūʻai, pono e loaʻa i ka mea kānana maikaʻi a pono e mālama i ka porosity kiʻekiʻe i nā pilikia i loaʻa i ka wā o ka kānana polymer melt.I mea e mālama ai i ka porosity kiʻekiʻe, ʻo kahi moena o nā ʻāpana o ka hapa nui o nā polymers wela ke ʻano e hana ai i ka gel e hōʻiliʻili a hōʻemi i ka pono kānana o ka media kānana.No laila, ʻaʻole pono e hoʻopili ka mea kānana metala ʻāpana a i ʻole ke kōkua ʻana i ka hana gel.
ʻOi aku ka loaʻa ʻana o ke one kai, akā ʻoi loa ka palupalu me ka hopena o ka ulu ʻana o nā ʻāpana maikaʻi e keakea i nā capillaries i loko o nā spinnerets.Eia hou, ʻo ka ʻili kiko o ke one kai he emi a emi iki ka pākēneka o ka porosity no kēlā me kēia pūʻulu kānana nui, no laila e piʻi nui ka puʻe.ʻO ka pauka metala ʻole i hoʻomākaukau ʻia ma lalo o nā kūlana kikoʻī e hōʻike ana i kahi ʻili ʻokoʻa loa e like me ke ʻano haʻahaʻa haʻahaʻa, e hoʻonui i kona pono kānana;Ma lalo o nā kaomi hana, hōʻike ia i ka ʻike a me ka hoʻoikaika ʻana i ke kūpaʻa ʻana i ka compressibility no ka maikaʻi o ka kānana pono me ka liʻiliʻi a ʻaʻole ʻole ka liʻiliʻi a me ka hāʻule ʻana.
FUTAI Koho Metala Pada
Manaʻo ʻo FUTAI i ka F-01 serial stainless metala one no polyester POY FDY filament e wili ana ma ke ʻano he media kānana waiwai;I mea e hoʻomaikaʻi ai i ka maikaʻi o ka wili, ua paipai ʻo FUTAI i ka S-03, kahi ikaika mechanical kiʻekiʻe a me ka liʻiliʻi o ka oxidization sensitive steel pauka;No ka hoʻohana ʻana i ke kaomi mua kiʻekiʻe, he koho maikaʻi ʻo S-04 no kona hoʻoikaika ʻana i ke kūʻē ʻana i ka compressibility, inert nui i ka polymer melts, ʻoi loa no ka hoʻohana ʻana i ka filament spinning PA.

1. Ka ikaika mechanical kiʻekiʻe.
2. ʻOi aku ka maikaʻi o ka hoʻopaʻa ʻana.
3. ʻAʻole kūpono ʻole.
4. Porosity kiʻekiʻe.
5. Inert nui i ka polymer hehee.
6. ʻOi aku ka lōʻihi o ke ola ʻana o ka pūʻolo milo.
7. ʻOi aku ka maikaʻi o ka wili.
Loaʻa nā Nui Mesh a me kona mau waiwai kino
I ka hana ʻana i ka wili filament, e like me ka POY a me ka FDY yarn, ʻo ka mea nui ka hoʻohui ʻana i kekahi mau ʻāpana pauka like ʻole e loaʻa ai ka hopena kānana maikaʻi loa.Hiki i ka FUTAI ke hāʻawi i nā mea kūʻai aku i ka koho maikaʻi loa o ka nui mesh e pili ana i kā mākou ʻike i ka pauka metala a me nā ʻike waiwai e pili ana i ka hana ʻana i ka wili fiber synthetic, i hiki i nā mea kūʻai ke hoʻohana piha i nā pono o ke one metala, hoʻonui. ke ola o ka wili milo a loaʻa ka maikaʻi o nā wili filament.
Ma kēia hope aku ka papa inoa o nā nui i loaʻa e like me ISO 4497 INTERNATION STANDARD FOR Metallic powders.Hiki ke hana ʻia nā ʻano nui ʻē aʻe ma ke noi.
