Nylons yog ib chav kawm ntawm plastics uas tau nyob ib puag ncig txij li xyoo 1930s.Lawv yog cov polyamide polymer ib txwm siv nyob rau hauv ntau cov txheej txheem tsim cov yas yas rau cov yeeb yaj kiab yas, hlau txheej thiab tubing rau roj thiab roj - thiab lwm yam.Feem ntau, nylons yog qhov nrov heev rau cov ntawv thov ntxiv vim tias lawv cov txheej txheem ua tau zoo, raws li tau hais hauv 2017 State of 3D Printing daim ntawv tshaj tawm txhua xyoo.Cov khoom siv SLS siv dav tshaj plaws yogPolyamide 12 (PA 12), tseem hu ua Nylon 12 PA 12 (tseem hu ua Nylon 12) yog cov yas siv dav dav nrog cov khoom siv dav dav thiab paub txog nws cov tawv tawv, tensile lub zog, cuam tshuam lub zog thiab muaj peev xwm flex tsis tawg.PA 12 tau ntev tau siv los ntawm kev txhaj tshuaj molders vim cov khoom siv tshuab.Thiab tsis ntev los no, PA 12 tau raug coj los ua cov khoom siv 3D luam ntawv los tsim cov khoom siv thiab cov qauv.
Nylon 12yog nylon polymer.Nws yog tsim los ntawm ω-amino lauric acid los yog laurolactam monomers uas txhua tus muaj 12 carbons, li no lub npe "Nylon 12".Nws cov yam ntxwv yog nruab nrab ntawm cov saw luv aliphatic nylons (xws li PA 6 thiab PA 66) thiab polyolefins.PA 12 yog ib tug ntev carbon saw nylon.Kev nqus dej tsawg thiab qhov ntom ntom, 1.01 g / mL, tshwm sim los ntawm nws qhov ntev hydrocarbon saw ntev, uas tseem ua rau nws qhov ruaj khov thiab yuav luag zoo li cov qauv paraffin.Cov khoom nylon 12 suav nrog cov yam ntxwv nqus dej qis tshaj plaws ntawm tag nrho cov polyamides, uas txhais tau tias txhua qhov chaw ua los ntawm PA 12 yuav tsum nyob ruaj khov hauv qhov chaw ntub dej.
Tsis tas li ntawd, polyamide 12 nrog cov tshuaj tiv thaiv zoo, nrog kev txo qis rau kev ntxhov siab tawg.Nyob rau hauv cov kev ua haujlwm qhuav qhuav, zawv zawg kev sib txhuam coefficient ntawm steel, POM, PBT thiab lwm yam ntaub ntawv yog tsawg, nrog zoo heev hnav tsis kam, stability, siab heev toughness, thiab tej yam kuj.Lub caij no, PA 12 yog ib qho hluav taws xob zoo hluav taws xob thiab, zoo li lwm yam polyamides, tsis cuam tshuam rau rwb thaiv tsev los ntawm ya raws.Dhau li ntawd, PA 12 ntev iav fiber reinforced thermoplastic khoom muaj suab nrov thiab kev co damping.
PAB 12tau siv los ua cov yas hauv kev lag luam tsheb tau ntau xyoo: piv txwv ntawm cov kav dej ntau yam ua los ntawm PA 12 muaj xws li cov roj kab, pneumatic nres kab, hydraulic kab, cua nkag system, cua boost system, hydraulic system, automotive electronics thiab teeb pom kev zoo, cua txias. thiab cua txias system, roj system, lub zog hluav taws xob thiab chassis nyob rau hauv cov tsheb ntawm suav tsis txheeb cov tuam txhab tsheb thoob ntiaj teb.Nws cov tshuaj tiv thaiv thiab cov khoom siv kho tshuab zoo heev ua rau PA 12 yog cov khoom siv zoo tshaj plaws rau kev sib cuag xov xwm uas muaj cov hydrocarbons.
Yog tias koj xav paub ntau ntxiv thiab xav ua 3d luam ntawv qauv, thov hu rauJSADD 3D Chaw tsim tshuaj paustxhua lub sijhawm.
