Nylon Powder Electrostatic Txau Txheej Txheej Txheej Txheem

Txoj kev tshuaj tsuag electrostatic siv cov nyhuv induction ntawm high-voltage hluav taws xob teb los yog kev sib txhuam them cov nyhuv rau induce opposite nqi ntawm lub nylon hmoov thiab cov khoom coated, feem. Tus nqi hmoov txheej yog attracted rau qhov oppositely them coated khoom, thiab tom qab melting thiab leveling, a nylon txheej yog tau. Yog hais tias cov txheej thickness yuav tsum tsis pub tshaj 200 microns thiab lub substrate yog non-cam khwb cia hlau los yog ntxeem tau, tsis muaj cua sov yuav tsum tau rau txias tsuag. Rau cov hmoov coatings uas yuav tsum tau thickness ntau dua 200 microns los yog substrates nrog cam khwb cia hlau los yog porous cov ntaub ntawv, lub substrate yuav tsum tau rhuab mus rau ib ncig ntawm 250 ° C ua ntej txau, uas yog hu ua kub txau.

Txias txau yuav tsum muaj cov hmoov nylon kom muaj txoj kab uas hla ntawm 20-50 microns. Qee lub sij hawm, cov dej pos huab tuaj yeem txau rau hauv cov hmoov kom nws muaj peev xwm nqa tau cov nqi thiab txo qhov tsis xws luag los ntawm cov hmoov poob ua ntej ci. Kev txau kub yuav tsum muaj cov hmoov nylon kom muaj txoj kab uas hla mus txog 100 microns. Coarser hais tuaj yeem ua rau cov coatings tuab, tab sis cov lus ntxhib ntau dhau tuaj yeem cuam tshuam cov hmoov adhesion. Thaum lub sij hawm kub txau, qhov kub ntawm lub substrate txo qis tsis tu ncua, ua rau nws nyuaj rau tswj lub thickness, tab sis lub txheej yuav tsis tsim cov hmoov tsis zoo.

Cov txheej txheem tshuaj tsuag electrostatic muaj ntau yam kev xaiv rau xaiv qhov ntau thiab tsawg ntawm cov khoom ua haujlwm, tshwj xeeb tshaj yog rau cov khoom ua haujlwm nrog cov thicknesses sib txawv, kom ntseeg tau cov thicknesses zoo sib xws. Thaum lub workpiece tsis yog coated tag nrho los yog muaj ib tug complex zoo uas yuav tsis tau immersed nyob rau hauv ib fluidized txaj, electrostatic txau txheej txheem muaj qhov zoo. High-temperature, hnav-resistant daim kab xev tuaj yeem siv los tiv thaiv ib ntus ntawm qhov tsis sib xws. Feem ntau, electrostatic txau tuaj yeem ua tiav cov txheej txheej nyias, xws li ntawm 150 microns thiab 250 microns. Tsis tas li ntawd, cov nylon txheej tau los ntawm electrostatic txias txau muaj qhov kub tsis tshua muaj melting, feem ntau nyob ib ncig ntawm 210-230 ° C rau 5-10 feeb, zoo toughness, thiab thermal degradation tsawg. Lub adhesion rau cov hlau yog zoo dua li lwm cov txheej txheem.
