Tooj liab cov yeeb nkab muaj ntau dua kev tiv thaiv thiab kub tiv thaiv thiab kub tsis kam tshaj txhuas cov yeeb nkab, zoo dua thermal conductivity, tab sis tus nqi siab dua; Aluminium yeeb nkab yog sib dua thiab pheej yig dua.
Ua ntej, kev sib piv ntawm cov khoom siv lub cev
Tooj liab raj muaj ib co coefficient ntawm thermal expansion, kub ua hauj lwm, yog li nws tau siv dav hauv thaj teb ntawm qhov kub siab; Thiab Aluminium cov hlab yog sib dua dua li cov qog caper, tab sis nws tsis zoo rau cov chaw khov kho, xws li cov cua txias thiab lwm yam.
Thib ob, qhov sib piv ntawm cov tshuaj lom neeg
Tooj liab lub raj corrosion yog qhov zoo dua, tsis cuam tshuam los ntawm roj thiab oxidation, thaum lub raj txhuas yooj yim rau kev ua kom haum. Tsis tas li ntawd, thaum lub tshuab tooj liab nyob ntev hauv kev sib cuag nrog oxygen nyob saum huab cua, nws cov npoo yuav tsim zaj duab xis tiv thaiv, uas pab tiv thaiv kom txhob muaj corrosion.
Thib peb, kev pabcuam lub neej ntawm kev sib piv
Qhov kev pabcuam lub neej ntawm tooj liab yeeb yog qhov tseem ceeb dua, txhuas cov yeeb nkab yog luv. Copper yeeb yeeb yeeb nkab kuj thiab cov kev ua tau zoo siab tau zoo heev, uas yog qhov zoo rau kev txhim kho nws lub neej pabcuam; Thiab txhuas cov yeeb nkab vim tsis muaj qhov yooj yim, puas yog tsis zoo li corrasion vim nws txoj kev pabcuam lub neej tsis tshua muaj luv.
Plaub, kev sib piv ntawm kev tiv thaiv ib puag ncig
Tooj liab lub raj rov qab siv ntau dua, muaj peev xwm siv cov pa phem ib puag ncig, txo cov kab mob ib puag ncig, hauv txoj kab nrog kev tiv thaiv thoob ntiaj teb; Thaum lub raj txhuas, txawm hais tias qhov kev pabcuam lub neej yog qhov luv luv, tab sis nws cov ntaub ntawv raw tuaj yeem rov ua tau zoo dua, yog li muaj qhov ua tau zoo ntawm kev tiv thaiv ib puag ncig.
Zuag qhia tag nrho, tooj liab thiab cov leeg txhuas muaj lawv tus kheej cov yam ntxwv. Tooj liab raj yog cov neeg siv hluav taws xob ntau, xeb thiab kub ua hauj, zoo dua thermal conductivity, tab sis tus nqi siab dua; Aluminium raj yog sib dua, pheej yig dua, tab sis thermal condior yog me ntsis qis dua me ntsis, yooj yim rau corrosion kev puas tsuaj. Nyob rau hauv kev xaiv, yuav tsum tau xaiv raws li cov ntaub ntawv thov tshwj xeeb thiab cov kev xav tau.
