Yuav ua li cas paub qhov txawv ntawm cov hlau strips thiab txhuas strips hauv optical cables?

Cov hlau strips thiab txhuas strips nyob rau hauv optical cables yog siv los tiv thaiv optical fibers los ntawm txhua yam sab siab thiab ya raws. Chrome-plated steel strips feem ntau yog siv nyob rau hauv zoo optical cables. Inferior optical cables hloov chrome-plated steel strips nrog cov ntawv hlau zoo tib yam lossis cov nplooj ntawv dub (tsis muaj steel strips) tsuas yog ib sab ntawm kev kho xeb. Thaum lub sij hawm, corrosion yuav tshwm sim nyob rau hauv lub optical cables, thiab hydrogen poob ntawm optical fibers kuj yuav nce. Nws yog ib qho yooj yim kom cais tawm los ntawm sheath los ua ib qho kev sib koom ua ke sheath, thiab nws cov dej noo thaiv kev ua tau zoo kuj tsis zoo; Qee qhov siv tin-plated steel strips es tsis txhob chrome-plated steel strips, thiab npuas nyob rau saum npoo ntawm tin-plated steel strips yog inevitable.
Yog li ntawd, corrosion yog feem ntau tshwm sim nyob rau hauv cov av noo thiab nto condensation los yog dej immersion tej yam kev mob, tshwj xeeb tshaj yog sai corrosion nyob rau hauv acidic tej yam kev mob. Cov tin txheej muaj cov cua sov tsis zoo, thiab nws cov ntsiab lus melting tsuas yog 232 degrees Celsius. Vim qhov kub siab thaum extruding lub sheath thaum lub sij hawm daim ntawv thov, muaj kev tsis meej nyob rau hauv lub tev lub zog, uas muaj feem xyuam rau cov noo noo tsis kam ntawm optical cable.
Lub melting point ntawm chromium nce mus txog 1900 degrees Celsius, thiab nws cov tshuaj muaj zog ruaj khov. Nws yuav tsis xeb thaum muab tso rau hauv huab cua los yog raus hauv dej ntawm chav tsev kub. Aluminium strips feem ntau siv cov khoom siv hluav taws xob uas tsis muaj hluav taws xob ua hluav taws xob hloov hluav taws xob hloov hluav taws xob cast-coated aluminium strips, uas yuav cuam tshuam rau kev ua haujlwm ntawm cov khoom siv kho qhov muag.
