Ib txoj hauv kev zoo tshaj plaws thiab ceev tshaj plaws los kho cov xim hauv ib puag ncig kev lag luam yog txoj kev kho cov khoom nto nrog cov hluav taws xob infrared. Rau qhov no, ib qho cuab yeej tshwj xeeb yog siv - IR-drying. Nws yog nyob ntawm nws cov yam ntxwv ntawm lub sijhawm uas cov xim dries, thiab qhov zoo ntawm cov xim pleev xim feem ntau nyob ntawm. Dab tsi yog infrared drying thiab dab tsi yog qhov zoo tshaj plaws, koj tuaj yeem pom ntawm no thiab tam sim no.
paint curing method
Tam sim no, muaj ntau txoj hauv kev uas cov cuab yeej siv tau qhuav sai sai tom qab siv qee cov txheej xim rau lawv:
Convective (siv cua kub).
Thermoradiation (siv infrared radiation).
Ua ke (ua ke ntawm thawj ob).
Ntawm lawv, qhov zoo tshaj plaws, tau kawg, yog IRhluav taws xob. Infrared drying (xws li IRT) tso cai rau koj los ua cov txheej txheem yuav luag txhua hom xim thiab primers, suav nrog dej thiab acrylic. Nyob rau tib lub sijhawm, cov cuab yeej tso cai rau koj kom nrawm nrawm ntawm cov txheej txheem hardening ntawm primer lossis putty. Cov khoom siv, uas raug rau yoj hluav taws xob, dhau los ntawm cov kua hauv lub xeev mus rau lub xeev cov khoom, uas yog hu ua hardening, nyob rau hauv cov lus ntawm cov kws tshwj xeeb. Ntxiv mus, tag nrho cov txheej txheem yuav siv sij hawm ntau tshaj 5 feeb.
Specifications
Infrared shortwave ziab ua haujlwm raws li hauv qab no. Tom qab txuas cov cuab yeej mus rau lub zog hluav taws xob (qhov no feem ntau yog hloov hluav taws xob tam sim no), cov txheej txheem saum toj kawg nkaus ntawm cov xim yog thawj rhuab nyob rau hauv cov txheej txheem txheej txheem, uas nyob rau hauv lem tag nrho tiv thaiv cov hnyav los ntawm kev khiav. Qhov no tshwm sim thaum luv-yoj infrared ziab ua haujlwm. Cov khoom siv ntev-yoj hloov lawv lub zog siv cov cua sov convection. Yog li, lub hauv paus uas radiates cua sov rau saum npoo ntawm cov xim thiab cov kua roj vanish mechanism yog rhuab mus rau ib tug kub ntawm txog 700-750 degrees Celsius, tom qab uas cov cua kub theem ntawm qhuav khoom nws tus kheej nce mus rau 40 degrees xwb. Raws li qhov tshwm sim, lub sijhawm txias ntawm cov cuab yeej yuav yog tsawg kawg 15-20 feeb, thaum nws yuav siv sijhawm li 1-2 feeb los kho cov txheej txheej ntawm cov xim.
Los ntawm txoj kev, qhov cua sov hauv cov khoom siv hluav taws xob ntev yog siab dua li cov khoom siv luv luv. Xws li infrared ziab tuaj yeem ua kom sov txog 1450 degrees Celsius. Yog li ntawd, nws ncethiab cua sov cov khoom kom qhuav. Vim li no, feem ntau ntawm cov cua sov lub zog (txog li 75 feem pua) tawm los ntawm lub cuab yeej tsis poob rau sab sauv, tab sis nyob rau hauv qis contour ntawm cov xim, tom qab ntawd hardening tshwm sim nyob rau sab nraud ntawm txheej.
Lawv siv qhov twg?
Niaj hnub nimno infrared ziab yog siv nyob rau hauv ntau lub lag luam ntawm kev lag luam thiab kev lag luam, vim nws tuaj yeem nqa lub npoo ntawm yuav luag txhua yam khoom siv rau qhov xav tau: MDF, hniav iav, hlau lub cev thiab ntau ntxiv. Tag nrho cov no ua rau nws tseem tsis tau muaj nyob rau hauv kev lag luam painting ntawm cov khoom thiab cov mechanisms.
