Nylon Powder Electrostatic Txau Txheej Txheej Txheej Txheem

Txoj kev txau electrostatic siv cov nyhuv induction ntawm lub zog hluav taws xob siab lossis cov nyhuv sib txhuam kom ua rau muaj cov nqi sib txawv ntawm cov hmoov nylon thiab cov khoom coated, raws li. Cov txheej hmoov them raug rub mus rau cov khoom coated uas muaj cov nqi sib txawv, thiab tom qab yaj thiab leveling, ib txheej nylon tau txais. Yog tias qhov tuab ntawm cov txheej tsis tshaj 200 microns thiab cov khoom siv tsis yog hlau cam khwb cia lossis porous, tsis tas yuav muaj cua sov rau kev txau txias. Rau cov txheej hmoov uas muaj qhov tuab ntau dua 200 microns lossis cov khoom siv nrog hlau cam khwb cia lossis cov khoom siv porous, cov khoom siv yuav tsum tau cua sov txog li 250 ° C ua ntej txau, uas hu ua kev txau kub.

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 txau electrostatic muaj ntau txoj kev xaiv rau kev xaiv qhov loj me ntawm cov khoom ua haujlwm, tshwj xeeb tshaj yog rau cov khoom ua haujlwm uas muaj cov tuab sib txawv, kom ntseeg tau tias cov tuab zoo sib xws. Thaum cov khoom ua haujlwm tsis tau coated tag nrho lossis muaj cov duab nyuaj uas tsis tuaj yeem muab tso rau hauv lub txaj fluidized , cov txheej txheem txau electrostatic muaj qhov zoo. Cov ntaub nplaum kub siab, hnav-resistant tuaj yeem siv los tiv thaiv cov khoom tsis coated ib ntus. Feem ntau, electrostatic txau tuaj yeem ua tiav cov txheej nyias dua, xws li ntawm 150 microns thiab 250 microns. Tsis tas li ntawd, cov txheej nylon tau los ntawm electrostatic txias txau muaj qhov kub yaj qis, feem ntau nyob ib puag ncig 210-230 ° C rau 5-10 feeb, zoo toughness, thiab qis thermal degradation. Kev nplaum rau cov hlau zoo dua li lwm cov txheej txheem.
