Yuav ua li cas Additively Manufactured PFA Heaters Enabling Complex, Siab -Tub, Tag nrho cov -Fluoropolymer Heater Geometries?
Tso lus
Tus txheej txheem PTFE immersion rhaub yog kaw kom yooj yim heev extruded los yog machined designs. PTFE feem ntau tsis tuaj yeem yaj thiab rov ua dua tshiab siv cov txheej txheem tshwj xeeb ntxiv, yog li cov khoom siv hluav taws xob fluoropolymer cua sov tau ntev ua cov raj ncaj, khoov rods, thiab welded fittings. Kev tuaj txog ntawm siab -kub 3D luam ntawv siv PFA yog hloov cov kev txwv no. Lub tshuab cua sov tuaj yeem tsim tau raws li ib qho, muaj cov organic thiab cov duab nyuaj - cov qauv cua sov ribbed nrog cov dej ntws sab hauv, kev sib koom ua ke mounting kho vajtse thiab cov kua dej directing nto tag nrho cov luam tawm ua ke ua ib qho chaw tsis muaj zog.
Additive manufacturing PFA heater complex geometry technology yog tsim muaj peev xwm tshiab rau thermal ua tshuab nrog corrosion kuj, compact installation thiab superior fluid dynamics.
Vim li cas PFA zoo rau 3D luam ntawv
PFA (perfluoroalkoxy alkane) yog ib tug tswv cuab ntawm tsev neeg fluoropolymer, uas kuj muaj xws li PTFE, tab sis nws muaj ntau yam sib txawv. Hauv kev muaj tiag, PTFE tsis yaj thaum rhuab, tab sis sinters hloov. Qhov no ua rau nws nyuaj heev rau kev ua haujlwm hauv 3D tshuab luam ntawv ib txwm muaj.
PFA tsis zoo li ntawd.
3D printability los ntawm melt processing
PFA yog cov yaj tiag tiag- cov khoom siv tau, uas txhais tau hais tias nws ntws thaum cua sov, thiab teem caij kwv yees thaum txias. Qhov no ua rau nws siv nyob rau hauv feem ntau niaj hnub additive manufacturing txuj ci, xws li:
Kub kub fused filament fabrication (FFF)
Laser hmoov txaj fusion
