Naironi ikirasi yakajairika yemapurasitiki anga aripo kubva kuma1930s.Iwo polyamide polymer yagara ichishandiswa mune akati wandei akajairwa mapurasitiki ekugadzira mafirimu epurasitiki mafirimu, simbi coating uye tubing yeoiri negesi - pakati pezvimwe zvinhu.Kazhinji, manylons anonyanya kufarirwa kune ekuwedzera maapplication nekuda kwekuita kwawo, sekunongedzerwa mu2017 State of 3D Printing chirevo chegore.Iyo inonyanya kushandiswa SLS zvinhu ndeyePolyamide 12 (PA 12), inozivikanwawo seNylon 12 PA 12 (inozivikanwawo seNylon 12) ipurasitiki yakanaka-yekushandisa ine yakakura yekuwedzera maapplication uye inozivikanwa nekuomarara kwayo, kusimba kwayo, simba rekuita uye kugona kuchinjika pasina kutyoka.PA 12 yagara ichishandiswa nemajekiseni molder nekuda kweaya ma mechanic properties.Uye nguva pfupi yadarika, PA 12 yakagamuchirwa seyakajairwa 3D kudhinda zvinhu zvekugadzira zvinoshanda zvikamu uye prototypes.
Nylon 12iri nylon polymer.Yakagadzirwa kubva ku ω-amino lauric acid kana laurolactam monomers iyo imwe neimwe ine 12 kabhoni, nekudaro zita rekuti "Nylon 12".Hunhu hwayo huri pakati pepfupi-cheni aliphatic naironi (senge PA 6 uye PA 66) uye polyolefins.PA 12 irefu kabhoni cheni naironi.Kunyura kwemvura yakaderera uye kuwanda, 1.01 g/mL, zvichibva mukureba kwayo kwecheni yehydrocarbon, iyo inopawo kugadzikana kwedimensional uye inenge yakafanana neparafini chimiro.Iyo Nylon 12 zvivakwa zvinosanganisira yakaderera kunyudzwa kwemvura maitiro eese mapolyamides, zvinoreva kuti chero zvikamu zvakagadzirwa kubva PA 12 zvinofanirwa kuramba zvakagadzikana munzvimbo dzine hunyoro.
Uye zvakare, polyamide 12 ine yakanaka makemikari kuramba, ine kuderedzwa kunzwisiswa kwekunetseka kutsemuka.Pasi pemamiriro ekushanda akaoma, iyo inotsvedza friction coefficient yesimbi, POM, PBT uye zvimwe zvinhu yakadzikira, ine yakanakisa kupfeka kuramba, kugadzikana, kusimba kwakanyanya, uye kukanganisa kuramba.Zvichakadaro, PA 12 yakanaka insulator yemagetsi uye, semamwe mapolyamides, haikanganisi insulation nehunyoro.Kunze kwezvo, PA 12 refu girazi faibha yakasimbisa thermoplastic zvinhu ine ruzha rwakanaka uye kudedera kunyorova.
PA 12yakashandiswa sepurasitiki muindasitiri yemotokari kwemakore mazhinji: mienzaniso yemapombi akawanda akagadzirwa nePA 12 anosanganisira mitsara yemafuta, pneumatic brake mitsara, hydraulic mitsara, air intake system, air boost system, hydraulic system, mota dzemagetsi uye mwenje, kutonhora. uye air conditioning system, oiri system, simba system uye chassis mumotokari dzevazhinji vagadziri vemotokari pasi rese.Kupokana kwayo kwemakemikari uye yakasarudzika michina zvinhu zvinoita kuti PA 12 ive yakanakira zvinhu zvekusangana midhiya ine mahydrocarbon.
Kana iwe uchida kuziva rumwe ruzivo uye uchida kugadzira 3d printing modhi, ndapota tauraJSADD 3D Mugadziringuva dzese.
