mea nailoe fa'aaogaina lautele, la'ititi i totini nailoni, tetele i le afi afi vaega pito i luga, ma isi, ua ufitia uma vaega o lo tatou olaga.E ese'ese le fa'aogaina o vaega, o mana'oga mo meafaitino o le nailon e eseese fo'i, e pei o le maualuga o le vevela, fa'aofuofu tete'e ma le a'afiaga o a'afiaga, vaila'au fa'ainisinia, manino ma maufetuuna'i.
Naillon masani, e masani ona faasino i PA6, PA66 lua ituaiga masani.Naillon masani i le faʻaleleia, faʻafefe afi ma isi suiga o le a iai pea ni faʻaletonu tetele, e pei o le malosi o le hydrophilicity, maualuga le vevela o le vevela, le lelei o le manino ma isi, faʻatapulaʻaina le tele o talosaga.
O le mea lea, ina ia faʻaleleia le faʻaletonu ma faʻateleina uiga fou, e masani lava e ala i le faʻalauiloaina o monomers synthetic fou, e mafai ona tatou maua se faasologa o nylon faʻapitoa ma uiga eseese e mafai ona faʻafeiloaʻi i taimi faʻaoga eseese, e masani ona vaevaeina imaualuga vevela nylon, nylon filifili umi carbon, nylon manino, mea fa'avae meaola nailoni ma nylon elastomer ma isi.
Ona, tatou talanoa e uiga i vaega o nylon faapitoa, o latou uiga ma talosaga.
Fa'avasegaga ma fa'ata'ita'iga fa'aoga onylon faapitoa
1. Tete'e maualuga vevela - nailon maualuga vevela
Muamua lava, o le nylon maualuga-vevela e faʻatatau i mea nylon e mafai ona faʻaaogaina i se siosiomaga i luga aʻe o le 150 ° C mo se taimi umi.
O le maualuga o le vevela o le naylon e masani ona maua e ala i le faʻaofiina o monomers manogi malosi.Mo se faʻataʻitaʻiga, o le nailoni uma-aromatic, o le sili ona masani o le DuPont's Kevlar, lea e saunia e le tali a le p-benzoyl chloride ma le p-phenylenediamine poʻo le p-amino-benzoic acid, e taʻua o le PPTA, e mafai ona faatumauina le malosi lelei i le 280 °. C mo le 200h.
Ae ui i lea, o le manogi atoa maualugavevela nylone le lelei i le faagasologa ma faigata ona ausia tui tui, o lea o le semi-aromatic maualuga vevela nylon tuufaatasi ma aliphatic ma aromatic e sili atu ona fiafia.I le taimi nei, o le tele o ituaiga nylon maualuga maualuga, e pei o le PA4T, PA6T, PA9T, PA10T, ma isi, e masani lava semi-aromatic maualuga-vevela nylon polymerized mai filifili saʻo aliphatic diamine ma terephthalic acid.
O le nylon maualuga maualuga e faʻaaogaina lautele i vaega taʻavale, vaega faʻainisinia ma vaega eletise / eletise.
2. Malosi maualuga - umi kaponi filifili nailon
O le lona lua o le nailon filifili umi carbon, lea e masani ona faasino i meafaitino nailon e sili atu i le 10 methylenes i le filifili mole.
I le tasi itu, o le nailon filifili umi carbon e sili atu vaega methylene, o lea e maualuga le malosi ma le vaivai.I le isi itu, o le faʻaitiitia o le mamafa o vaega amide i luga o le filifili mole e faʻaitiitia ai le hydrophilicity ma faʻaleleia lona tulaga mautu, ma o ona ituaiga o PA11, PA12, PA610, PA1010, PA1212 ma isi.
I le avea ai o se vaega taua o palasitika inisinia, o le nailon filifili umi carbon e maua ai le lelei o le maualalo o le vai, lelei le maualalo o le vevela, tele mautu, malosi lelei, faʻalavelave faʻalavelave faʻafuaseʻi, ma isi, ma e faʻaaogaina lautele i taavale, fesoʻotaʻiga, masini. , mea fa'aeletoroni, aerospace, mea tau ta'aloga ma isi fa'alapotopotoga.
3. Malamalama maualuga - nylon manino
Naillon masani e masani ona translucent foliga vaaia, transmittance malamalama i le va o le 50% ma le 80%, ma manino le nailon transmittance e masani lava e sili atu nai lo le 90%.
E mafai ona suia le nylon manino i auala fa'aletino ma vaila'au.Ole auala fa'aletino ole fa'aopoopoina lea ole nucleating agent ma fa'aitiitia lona tele o saito ile va'aiga ole umi ole galu e maua ai microcrystalline transparent nylon.O le auala fa'ama'i o le fa'aofiina lea o le monomer o lo'o i ai vaega itu po'o le fa'amama mama, fa'aumatia le masani o filifili mole, ma maua mai le nailon manino amorphous.
E mafai ona faʻaaogaina le nailoni manino mo meainu ma meaʻai afifi, ae mafai foi ona gaosia meafaifaʻaili ma vaega komepiuta, gaosiga o fale gaosi oloa o le mataʻituina o Pupuni, faʻamalama meafaifaʻaili X-ray, meafaifaʻaili mita, faʻapipiʻi masini faʻapipiʻi eletise eletise, ufiufi moli faʻapitoa, ipu ma pusa faʻafesoʻotaʻi meaʻai. .
4. Mauaina – Bio-fa'avaeMeafaitino Nylon
I le taimi nei, o le tele o monomers synthetic o ituaiga nylon e mai le auala suauu suauu, ma o le monomer synthetic o bio-faavae mea nylon e mai le bio-fa'avae ala fa'ameamea, e pei o Arkema e ala i le castor suauʻu auala e maua ai amino undecanoic acid ona sosoo ai lea ma le nailon synthetic 11.
Pe a faatusatusa i le naillon faavae suauu masani, o le bio-faavae mea nylon e le gata e taua maualalo-carbon ma le siosiomaga lelei, ae mafai foi ona ausia manaoga eseese faatinoga o le fofo, e pei o Shandong Kaisai bio-faavae PA5X faasologa, Arkema Rilsan fa'asologa i vaega ta'avale, mea fa'aeletoroni ma fale lomitusi 3D ma isi vaega ua fa'aaogaina lelei.
5.Maualuluga maualuga -- elastomer nylon
Nailoni elastomere faatatau i ituaiga nailoni e maualuga le maufetuunaʻi, mama mama ma isi uiga, ae e taua le taʻua o le filifili mole mole o le elastomer nylon e le o vaega uma o filifili polyamide, ma polyether poʻo le polyester filifili vaega, o le ituaiga pisinisi sili ona taatele o le polyether poloka amide (PEBA).
O uiga faʻatinoga o le PEBA e maualuga le malosi, toe faʻaleleia lelei, maualuga le maualuga o le vevela o le malosi, sili atu le maualalo o le vevela, faʻataʻitaʻiga lelei antistatic, ma isi mea, lea e faʻaaogaina i seevae mauga, seevae faʻaseʻe, faʻamalo mea ma faʻamaʻi fomaʻi.
