Raws li cov khoom tseem ceeb txuas nrog ntau yam khoom siv hluav taws xob, cov hlua hluav taws xob hauv hluav taws xob muaj kev cuam tshuam ncaj qha rau kev ruaj ntseg thiab kev ntseeg siab ntawm cov khoom siv.Cov khoom tseem ceeb ntawm cov hlua hlau txiav txim siab nws cov conductivity, kub tsis kam, yooj, thiab tiv thaiv - cuam tshuam muaj peev xwm. Yog li ntawd, kev nkag siab txog cov ntaub ntawv tseem ceeb ntawm cov hlua hluav taws xob hluav taws xob yog qhov tseem ceeb.
Cov khoom siv hluav taws xob yog cov khoom tseem ceeb ntawm cov hlua hluav taws xob thiab feem ntau yog ua los ntawm siab -purity tooj liab lossis tooj liab alloys. Copper muaj qhov zoo tshaj plaws conductivity thiab ductility, zoo txo hluav taws xob tiv thaiv thiab txo qis zog poob. Hauv qee qhov tshwj xeeb daim ntawv thov, xws li siab- qhov kub thiab txias qhov chaw yuav tsum muaj zog dua, cov alloys xws li tinned tooj liab, nyiaj-plated tooj liab, los yog tooj liab- clad steel yog siv los txhim kho corrosion kuj thiab mechanical zog.
Cov khoom siv rwb thaiv tsev encases cov conductors, tiv thaiv luv luv Circuit Court thiab tiv thaiv cov hlua khi los ntawm ib puag ncig cuam tshuam. Cov ntaub ntawv rwb thaiv tsev muaj xws li PVC (polyvinyl chloride), PE (polyethylene), Teflon (polytetrafluoroethylene), thiab hla -txuas polyethylene (XLPE). PVC yog dav siv nyob rau hauv dav siv hluav taws xob xaim hlua vim nws tus nqi qis thiab zoo heev yooj. PE thiab XLPE muaj qhov kub thiab txias thiab tshuaj tiv thaiv, ua rau lawv haum rau qhov hnyav ib puag ncig xws li tsheb thiab khoom siv. Teflon, nrog rau nws zoo heev - kub thiab siab -voltage resistance, feem ntau yog siv nyob rau hauv siab -kawg daim ntaub ntawv xws li aerospace.
Tsis tas li ntawd, cov txheej tiv thaiv sab nrauv ntawm cov hlua khi feem ntau siv cov nylon braid, PVC tsho, los yog hlau ntaub thaiv npog los txhim kho tensile lub zog, abrasion tsis kam, thiab electromagnetic cuam tshuam.
Hauv cov ntsiab lus, kev xaiv cov khoom siv rau cov hlua hluav taws xob hluav taws xob yuav tsum tau ua kom zoo raws li cov ntawv thov tshwj xeeb kom ntseeg tau tias qhov zoo sib npaug ntawm cov khoom siv hluav taws xob, kev ua haujlwm ntev, thiab kev hloov pauv ib puag ncig. Nyob rau hauv lub neej yav tom ntej, nrog rau kev tsim cov khoom siv thev naus laus zis tshiab, kev ua haujlwm ntawm cov hlua hluav taws xob yuav raug txhim kho ntxiv kom tau raws li qhov xav tau ntawm kev sib txuas hluav taws xob ntau dua.
