Inayiloni ludidi oluqhelekileyo lweeplastiki ezikho ukusukela ngoo-1930.Ziyipolymer ye-polyamide ngokwesiko esetyenziswa kwiinkqubo ezininzi zeplastiki eziqhelekileyo zokwenziwa kweefilimu zeplastiki, iingubo zentsimbi kunye netyhubhu ye-oyile negesi - phakathi kwezinye izinto.Ngokubanzi, iinayiloni zithandwa kakhulu kwizicelo ezongezelelweyo ngenxa yokuqhubekeka kwazo, njengoko kukhankanyiwe kwi-2017 State of 3D Printing ingxelo yonyaka.Eyona nto isetyenziswa kakhulu kwi-SLS imathiriyeliIPolyamide 12 (PA 12), ekwaziwa ngokuba yiNylon 12 PA 12 (ekwabizwa ngokuba yiNylon 12) yiplastiki elungileyo yokusetyenziswa ngokubanzi kunye nezicelo ezongezelelweyo ezibanzi kwaye yaziwa ngokuqina kwayo, amandla okuqina, amandla empembelelo kunye nokukwazi ukuguquguquka ngaphandle kokuqhekeka.I-PA 12 kudala isetyenziswa ngababumbi besitofu ngenxa yezi mpawu zomatshini.Kwaye kutshanje, i-PA 12 yamkelwe njengento eqhelekileyo yoshicilelo lwe-3D yokwenza iindawo ezisebenzayo kunye neeprototypes.
Inayiloni 12yipolima enayiloni.Yenziwe kwi-ω-amino lauric acid okanye i-laurolactam monomers ukuba nganye ine-carbons ye-12, ngoko ke igama elithi "Nylon 12".Iimpawu zayo ziphakathi kweenayiloni ezimfutshane ze-aliphatic (ezifana ne-PA 6 kunye ne-PA 66) kunye ne-polyolefins.PA 12 yinayiloni yekhabhoni ende.Ukufunxwa kwamanzi asezantsi kunye noxinaniso, 1.01 g/mL, isiphumo sobude betsheyina lehayidrobhoni yehayidrobhoni omde, nto leyo inika uzinzo lwe-dimensional kunye nolwakhiwo oluphantse lufane neparafini.Iimpawu zeNylon 12 ziquka ezona mpawu zisezantsi zokufunxa amanzi kuzo zonke iipolyamides, okuthetha ukuba naziphi na iinxalenye ezenziwe kwi-PA 12 kufuneka zihlale zizinzile kwiindawo ezinomswakama.
Ukongeza, i-polyamide 12 enokumelana neekhemikhali ezilungileyo, kunye nokunciphisa uvakalelo kuxinzelelo lokuqhekeka.Ngaphantsi kweemeko zokusebenza ezinomileyo, i-coefficient ye-sliding friction yentsimbi, i-POM, i-PBT kunye nezinye izinto ziphantsi, kunye nokumelana okugqwesileyo kokunxiba, ukuzinza, ukuqina okuphezulu kakhulu, kunye nokuchasana kwempembelelo.Ngeli xesha, i-PA 12 sisithinteli sombane esilungileyo kwaye, njengezinye iipolyamides, ayichaphazeli ukugquma ngokufuma.Ngaphandle koko, i-PA 12 ifayibha ende yeglasi eyomeleziweyo imathiriyeli ye-thermoplastic inengxolo elungileyo kunye ne-vibration damping.
PA 12isetyenziswe njengeplastiki kushishino lweemoto iminyaka emininzi: imizekelo yemibhobho emininzi eyenziwe nge-PA 12 ibandakanya imigca yepetroli, imigca ye-pneumatic brake, imigca ye-hydraulic, inkqubo yokuthatha umoya, inkqubo yokunyusa umoya, inkqubo ye-hydraulic, i-automotive electronics kunye nokukhanyisa, ukupholisa. kunye nenkqubo yokupholisa umoya, inkqubo ye-oyile, inkqubo yamandla kunye ne-chassis kwizithuthi zabenzi beemoto ezingenakubalwa kwihlabathi liphela.Ukumelana kwayo neekhemikhali kunye neempawu ezibalaseleyo zoomatshini zenza i-PA 12 ibe yinto efanelekileyo kumajelo onxibelelwano aqulethe i-hydrocarbons.
Ukuba ufuna ukwazi ulwazi oluninzi kwaye ufuna ukwenza imodeli yoshicilelo ye-3d, nceda uqhagamshelaneJSADD 3D Manufacturerngalo lonke ixesha.
