Dab tsi yog Aircraft Deicing?
Dav hlau deicingyog cov txheej txheem ntawm kev tshem tawm cov kab mob khov los ntawm qhov chaw dav hlau ua ntej yuav tawm mus, ua kom muaj kev nyab xeeb ntawm kev ua haujlwm. Nws suav nrog ob kauj ruam:
Deicing: Siv cov kua dej kub kom yaj cov dej khov, daus, los yog khov.
Anti-icing: Txheej txheej nrog cov kua dej los tiv thaiv cov dej khov tshiab thaum lub sij hawm hauv av.
Deicing thiab anti-icing systems ntawm aircraftntxiv dag zog rau hauv av, nrog rau qee lub dav hlau nruab nrog cua sov tis lossis kiv cua. Txawm li cas los xij, hauv av deicing tseem tseem ceeb, tswj los ntawm kev cob qhiaaircraft deicing techniciansraws li nrujdeicing aircraft cov txheej txheem.
Hom Deicing Fluids
Deicing kua yog categorized ua plaub hom, txhua tus muaj cov khoom tshwj xeeb (Ground Icing: Fluid Basics):
Hom I: Tsawg-viscosity kua rau deicing, thov kub, nrog luv HOTs.
Hom II: Thickened fluids rau anti-icing, muab ntev HOTs, siv nyob rau hauv cov teb chaws Europe.
Hom III: Sib npaug rau cov dav hlau me me, nrog rau HOTs nruab nrab.
Hom IV: High-viscosity fluids rau cov dav hlau loj, muab cov HOTs ntev tshaj plaws.
Cov kua dej no feem ntau yog glycol-raws li, nrog propylene glycol nyiam vim qis toxicity.

Qhov ceev ntawm deicing kua txiav txim lawv cov kev ua tau zoo:
Txias Point: Ib qho 70% glycol sib tov tuaj yeem txo qhov chaw khov rau -67 ° F (-55 ° C), piv rau -18 ° F (-28 ° C) rau cov kua dej tsis muaj dej.
viscosity: Muaj feem cuam tshuam rau kev txau thiab adhesion, tseem ceeb rau cov kua dej tiv thaiv icing.
Lub Sijhawm Holdover (HOT): Ua kom muaj kev tiv thaiv ntev ua ntej yuav tawm mus.
Kev siv qis tshaj qhov kub thiab txias (LOUT): Txhais qhov txias tshaj plaws uas cov kua dej tseem siv tau.
Qhov ntom ntom tsis raug tuaj yeem ua rau:
Hauv qab-dilution: Ntau dua viscosity, tsis sib xws, thiab cov dej khib nyiab.
Tshaj-dilution: Siab dua qhov chaw khov, txo kev ua haujlwm thiab kev nyab xeeb.
Environmental thiab nqi cuam tshuam
Deicing kua yog kim, nrog rau txhua xyoo US siv kwv yees li ntawm 25 lab nkas loos. Kev siv ntau dhau ua rau tus nqi nce ntxiv, thaum kev pov tseg tsis raug ua rau muaj kev txhawj xeeb txog ib puag ncig, xws li dej hauv av.Deicer density ntsuaspab txhim kho kev siv thiab tswj cov khoom pov tseg, txhawb kev ua raws li cov cai xws li los ntawm Lub Chaw Tiv Thaiv Ib puag ncig (EPA).
Lub luag haujlwm ntawm Deicing Fluid Density Meters
Dab tsi yog Deicing Fluid Density Meters?
Deicing fluid density metersntsuas qhov ceev ntawm deicing kua, uas sib cuam tshuam nrog glycol ntom. Ultrasonic lossis sonic ceev raws li ntsuas ntsuas, xws li cov los ntawm , siv lub suab nthwv dej los ntsuas qhov ceev ntawm lub sijhawm tiag tiag, muab cov tshuaj tsis muaj kev cuam tshuam rau qhov chaw hnyav.
Cov ntawv thov hauv Aircraft Deicing
Deicer density metersfeem ntau yog siv rau:
Kev saib xyuas hauv kab: Ntsuas qhov ntom ntom hauv cov kav xa dej (piv txwv li, DN 50), cov kab sib sau, lossis cov kav dej.
Kev Tswj Pov Hwm: Txiav txim siab cov ntsiab lus glycol seem hauv cov dej khib nyiab rau kev rov ua dua (> 1%) lossis tso tawm.
Txheej txheem tswj: Ua kom cov kua dej zoo ib yam thaum sib xyaw thiab siv.
Cov meters no txhawb nqaaircraft deicing systemslos ntawm kev muab cov ntaub ntawv tsis tu ncua, txo kev cia siab rau kev kuaj sim.
