Amanayiloni ziyikilasi elivamile lamapulasitiki abelokhu ekhona kusukela ngawo-1930.Ziyipolymer ye-polyamide ngokujwayelekile esetshenziswa kwizinqubo eziningi zokukhiqiza zepulasitiki ezijwayelekile zamafilimu epulasitiki, izimbotshana zensimbi namashubhu kawoyela negesi - phakathi kwezinye izinto.Ngokuvamile, amanayiloni adume kakhulu kwezinhlelo zokusebenza ezingeziwe ngenxa yokusetshenzwa kwawo, njengoba kushiwo embikweni wonyaka we-2017 State of 3D Printing.Izinto ezisetshenziswa kakhulu ze-SLS ziyiI-Polyamide 12 (PA 12), eyaziwa nangokuthi inayiloni 12 PA 12 (ephinde yaziwe ngokuthi inayiloni 12) iyipulasitiki ekahle yokusebenzisa jikelele enezithako ezibanzi futhi yaziwa ngokuqina kwayo, amandla aqinile, amandla omthelela kanye nekhono lokugoba ngaphandle kokuphuka.I-PA 12 kade isetshenziswa ngababumba umjovo ngenxa yalezi zakhiwo zemishini.Futhi muva nje, i-PA 12 yamukelwe njengento evamile yokuphrinta ye-3D yokwakha izingxenye ezisebenzayo nama-prototypes.
Inayiloni 12iyi-polymer enayiloni.Yenziwe nge-ω-amino lauric acid noma i-laurolactam monomers ukuthi ngayinye inamakhabhoni ayi-12, yingakho igama elithi “Nylon 12”.Izici zayo ziphakathi kwamanyloni e-aliphatic e-short-chain (njenge-PA 6 ne-PA 66) kanye nama-polyolefin.I-PA 12 iyinayiloni yeketango lekhabhoni ende.Ukumuncwa kwamanzi aphansi kanye nokuminyana, 1.01 g/mL, kuwumphumela wobude beketanga le-hydrocarbon emide kakhulu, elinikeza nokuqina kobukhulu kanye nesakhiwo esicishe sifane nopharafini.Izakhiwo zeNylon 12 zihlanganisa izici eziphansi zokumunca amanzi zazo zonke i-polyamides, okusho ukuthi noma yiziphi izingxenye ezenziwe nge-PA 12 kufanele zihlale zizinzile endaweni enomswakama.
Ngaphezu kwalokho, i-polyamide 12 enokumelana okuhle kwamakhemikhali, nokuzwela okuncishisiwe ekuqhekekeni kwengcindezi.Ngaphansi kwezimo zokusebenza ezomile uma kuqhathaniswa, i-coefficient ye-sliding friction yensimbi, i-POM, i-PBT nezinye izinto iphansi, inokumelana nokugqokwa okuhle kakhulu, ukuzinza, ukuqina okuphezulu kakhulu, nokumelana nomthelela.Ngaleso sikhathi, i-PA 12 iyisivikeli esihle sikagesi futhi, njengamanye ama-polyamides, ayithinti ukufakwa umswakama ngomswakama.Ngaphandle kwalokho, i-PA 12 yengilazi ende yefayibha eqinisiwe ye-thermoplastic inomsindo omuhle nokuncibilika kokudlidliza.
PA 12Sekuyiminyaka eminingi isetshenziswa njengepulasitiki embonini yezimoto: izibonelo zamapayipi e-multilayer enziwe nge-PA 12 zifaka imigqa yamafutha, imigqa ye-pneumatic brake, imigqa ye-hydraulic, uhlelo lokungenisa umoya, uhlelo lokukhulisa umoya, uhlelo lwe-hydraulic, ugesi wezimoto nokukhanyisa, ukupholisa. kanye nohlelo lwe-air conditioning, uhlelo lukawoyela, uhlelo lwamandla kanye ne-chassis ezimotweni zabakhiqizi bezimoto abangenakubalwa emhlabeni jikelele.Ukumelana kwayo namakhemikhali kanye nezakhiwo ezivelele zemishini kwenza i-PA 12 ibe into efanelekile yemidiya yokuxhumana equkethe ama-hydrocarbon.
Uma ufuna ukwazi ulwazi olwengeziwe futhi udinga ukwenza imodeli yokuphrinta ye-3d, sicela uxhumaneI-JSADD 3D Manufacturerzikhathi zonke.
