Txheej Txheem Txheej Txheem ntawm Hlau Tubular Cua Kub Tube

Magnesium oxide hmoov filling muaj ob qho tib si rwb thaiv tsev thiab muaj zog thermal conductivity. Ntau lub tuam txhab ua lag luam tsis zoo tsim cov khoom siv hluav taws xob tsis zoo siv cov khoom siv tsis zoo - quartz xuab zeb. Tom qab cov khoom ntim tau muab tso rau, cov yeeb nkab yog tom qab siv lub tshuab shrinking kom compact oxide nruab nrab, kom ntseeg tau tias cov hluav taws xob cua sov hlau yog cais tawm ntawm huab cua thiab qhov chaw nruab nrab tsis hloov thiab sib tsoo nrog cov yeeb nkab phab ntsa. Nyob rau hauv txoj kev no, cov cua kub tso tawm ib cheeb tsam tuaj yeem nce ntau tshaj kaum npaug.

Hlau tubular cua sov tube qauv: insulator, sealing khoom, txhuas tawm pas nrig, filling khoom, hluav taws xob cua sov hlau, hlau tiv thaiv lub tes tsho, thiab lub davhlau ya nyob twg.

① Insulator: Feem ntau, lub taub hau dawb porcelain yog siv.

② Sealing khoom: (tseem nkag siab txog nws txoj haujlwm) Cov khoom siv sealing feem ntau yog siv los tiv thaiv cov ntaub ntawv rwb thaiv tsev los ntawm kev nqus dej vapor yooj yim hauv ib puag ncig, kom ntseeg tau tias lub tshuab hluav taws xob cua sov muaj kev ua haujlwm zoo. Cov khoom siv sib khi feem ntau suav nrog: xim zaj duab xis, cov xim silicone organic, epoxy resin, silicone roj hmab (peb tsuas yog siv cov roj hmab silicone) thiab lwm yam ntsaws ntsaws.

③ Lead tawm pas nrig: Feem ntau, hlau yog siv vim nws qhov kev hloov hluav taws xob hloov tau ceev heev

④ Fillers: Feem ntau, muaj magnesium oxide hmoov thiab quartz xuab zeb. Peb tsis siv quartz xuab zeb los tsim hluav taws xob cua sov raj, thiab pheej yig hluav taws xob cua sov raj ntawm lub khw yog txhua yam ua los ntawm quartz xuab zeb. Peb magnesium oxide hmoov yog ua los ntawm kev hloov kho magnesium oxide hmoov. Lub tshuab hluav taws xob cua sov ua los ntawm kev hloov kho magnesium oxide hmoov yog noo-pov thawj.

⑤ Hluav taws xob cua sov hlau: feem ntau suav nrog hlau chromium aluminium thiab nickel chromium alloy hlau. Hlau chromium txhuas yog pheej yig dua, feem ntau tsis muaj cov lus qhia tshwj xeeb. Hlau chromium aluminium alloy xov hlau yog siv rau hauv cov kav hluav taws xob cua sov. Nickel chromium alloy hlau yog kim dua. Qhov sib txawv ntawm ob lub xov hlau: Kev ua haujlwm kub ntawm cov hlau chromium aluminium alloy cov ntaub ntawv tuaj yeem ncav cuag 1400 degree, uas yog txaus los ua kom tau raws li qhov xav tau ntawm cov raj cua sov. Txawm li cas los xij, npib tsib xee chromium hlau muaj qhov yooj yooj yim thiab oxidation tsis kam, thaum hlau chromium txhuas hlau yog nkig.

⑥ Lub tes tsho tiv thaiv hlau: Cov khoom tseem ceeb yog stainless hlau (SUS201, 304, 321, 316, 310, thiab lwm yam), tooj liab liab, thiab carbon hlau (hlau). Xaiv lub tes tsho tiv thaiv hlau sib txawv raws li qhov chaw ua haujlwm sib txawv.
