Cov pa luam yeeb rau Range Hoods!
Feem ntau muaj peb hom pa luam yeeb kav rau ntau lub hoods:hloov tau aluminium foil cua ducts, polypropylene kav (yas) thiab PVC kav.Cov kav dej ua los ntawm PVC tsis yog ib txwm muaj.Cov kav dej no feem ntau yog siv rau qhov ntev ntev xws li 3-5 meters.Cov pa taws ua pa tawm ntawm cov yeeb nkab nyob deb yog tseem zoo heev.
Muaj ob lub kav dej, hloov pauv tau aluminium foil cua duct thiab polypropylene yeeb nkab.Lub hom phiaj hais lus, qee cov tuam txhab tsim cov txheej txheem aluminium ntawv ci raj yog luv luv, thiab cov qauv polypropylene (yas) raj feem ntau yog qhov ntev.Txhua yam nyob rau hauv tag nrho nws yog hais txog kev ua ib tug profit.
Qhov zoo ntawm aluminium foil tube yog tias nws yog opaque, txawm tias muaj roj ntau npaum li cas nyob rau sab nraud, nws yuav zoo li "huv".Thib ob, cov cua sov ua haujlwm ntawm cov khoom siv tau yooj yim aluminium foil cua ducts zoo dua li cov yeeb nkab yas fittings.Qhov zoo ntawm lub raj polypropylene yog nws yooj yim los tswj thiab hloov.Cov kev sib txuas ntawm pem hauv ntej thiab nram qab yog screwed rau yooj yim disassembly, tab sis nws yog ib tug pob tshab raj.Yog li ntawd, qhov tsis zoo ntawm cov kav dej yas yog tias lawv muaj pob tshab thiab yooj yim pom tias cov pa luam yeeb yog qias neeg, uas ua rau "tsis pom zoo";Qhov thib ob yog cov cua kub tsis kam, qhov kub tsis kam ntawm polypropylene tsis muaj zog npaum li qhov hloov pauv ntawm aluminium foil cua ducts, tsuas yog 120 ° C, tab sis qhov no tsis haum rau cov roj fume ntawm ntau lub hood.Nws yog kiag li muaj peev xwm.
Nyob rau hauv cov ntsiab lus, nyob rau hauv cov nqe lus ntawm kev siv cov nyhuv: txhuas ntawv ci raj yog sib npaug rau polypropylene hlab;Kev zoo nkauj: aluminium foil raj zoo dua li cov raj polypropylene;nyob rau hauv cov nqe lus ntawm tshav kub kuj: txhuas ntawv ci raj yog zoo dua polypropylene hlab;yooj yim: polypropylene hlab yog zoo dua li polypropylene hlab nyob rau hauv aluminium foil raj.
