Structure Composition & Heat Conduction Principple of Industrial Coated Tubular rhaub
Ntau tus neeg siv nkag siab yuam kev tias coated tubular heaters tsuas yog ntxiv cov txheej txheem yooj yim ntawm lub hauv paus ntawm cov cua sov zoo tib yam, tsis quav ntsej cov txheej txheem kev ua kom zoo sib xws hauv cov khoom. Inferior coated heaters tsuas yog ua tiav cov tshuaj tsuag sab nraud yam tsis muaj kev hloov pauv hauv cov txheej txheem, ua rau tsis muaj qhov sib npaug ntawm cov cua sov, txheej txheej hauv zos overheating thiab nrawm nrawm. Standard industrial coated tubular heaters txais kev sib xyaw ua ke ntawm cov txheej txheem kev tiv thaiv sab nraud thiab cov cua sov sab hauv, nrog rau txhua qhov sib txuam ua haujlwm corrosive xav tau.
Cov txheej txheem ua tiav ntawm cov txheej txheem tsim nyog coated tubular tso cua sov muaj rau 6 qhov tseem ceeb ua haujlwm, tsim cov txheej txheem tiv thaiv thiab cov txheej txheem cua sov los ntawm sab hauv mus rau sab nraud. Cov innermost siab-kub alloy cua sov hlau yog cov tub ntxhais cov cua sov- tsim cov khoom, nrog ruaj khov resistivity thiab siab -kub oxidation kuj, kom ntseeg tau tas li thiab niaj hnub cua sov tso zis. The middle dense insulating filling layer adopts high-purity modified magnesium oxide material, which realizes electrical isolation between heating wire and metal tube wall while improving heat conduction efficiency, avoiding internal heat accumulation and electric leakage risks.
Cov hlau raj substrate yog lub nruab nrab kub conduction cab kuj, feem ntau yog ua los ntawm 304 los yog 316L stainless hlau nrog ruaj khov kev ua tau zoo. Lub phab ntsa du thiab seamless muab lub hauv paus tiaj tus rau cov txheej txheej adhesion, tiv thaiv txheej hollowing thiab tev tawm los ntawm qhov tsis sib xws ntawm cov substrate. Cov txheej tiv thaiv sab nrauv yog cov tseem ceeb tiv thaiv -corrosion barrier, uniformly sprayed thiab kho nyob rau hauv cov hlau raj nto los ua ib tug compact cais txheej, kiag li cais tawm sab nraud corrosive media los ntawm cov hlau substrate.
Lub davhlau ya nyob twg sealing tivthaiv thiab thaiv cov qauv yog tshwj xeeb yog kho dua tshiab rau corrosive ib puag ncig. Tshwj xeeb los tiv thaiv -corrosion sealing kua nplaum thiab sealing nplhaib cov ntaub ntawv raug saws kom tsis txhob ya raws thiab corrosive gas nkag los ntawm lub raj kawg qhov sib txawv. Cov tshuaj tiv thaiv -oxidation xov hlau davhlau ya nyob twg tiv thaiv electrochemical corrosion nyob rau hauv cov av noo thiab corrosive ib puag ncig, kom ntseeg tau ntev - lub sij hawm ruaj khov Circuit Court txuas. Qee cov qauv siab -cov qauv muaj tseeb yog nruab nrog cov khoom siv ntsuas kub sib xws kom paub txog qhov tseeb -lub sijhawm ntsuas kub thiab kev hloov kho meej.

Lub hauv paus ntsiab lus ua haujlwm ntawm coated tubular heaters tsim ib qho kev sib koom ua ke ntawm kev hloov hluav taws xob hluav taws xob thiab kev tiv thaiv- tiv thaiv corrosion. Tom qab lub hwj chim- rau, cov cua sov xaim tsim cov cua sov tsis sib xws, uas yog ruaj khov mus rau phab ntsa hlau raj los ntawm cov txheej txheem rwb thaiv tsev. Cov phab ntsa hlau hlau hloov cov cua sov mus rau sab nraud corrosive media los ntawm qhov siab - txheej txheej txheej. Cov txheej txheej txheej tsis cuam tshuam rau kev siv hluav taws xob thaum thaiv cov tshuaj lom neeg yaig, ua kom pom tseeb ntawm kev ua kom muaj cua sov zoo thiab cov khoom siv tiv thaiv.
Raws li cov ntaub ntawv ntsuam xyuas cov qauv, kev sib xyaw ua ke zoo tshaj plaws coated heaters muaj 30% siab dua cov cua sov conduction uniformity thiab 50% ntev txheej txheej kev pab cuam lub neej tshaj li yooj yim sprayed hloov cua sov. Kev tsim qauv kev sib xyaw ua ke tuaj yeem hloov kho kom haum rau ntev - lub sijhawm ua haujlwm tsis tu ncua ntawm corrosive industrial cua sov tshuab.
