Cov kav hlau txais xov tooj liab feem ntau yog tsim los ntawm cov khoom siv tooj liab uas muaj cov khoom siv hluav taws xob zoo heev, thaum tseem suav nrog cov khoom siv dag zog, kev tiv thaiv corrosion, thiab cov nqi txiav txim siab. Ntshiab tooj liab (Red Copper) thiab tooj dag yog ob qho ntawm cov kev xaiv dav tshaj plaws. Raws li cov khoom tseem ceeb hauv kev sib txuas lus wireless, kev ua tau zoo ntawm kav hlau txais xov tooj liab tubing ncaj qha cuam tshuam cov teeb liab kis tau zoo thiab kev ruaj ntseg. Yog li ntawd, kev xaiv cov khoom siv yuav tsum tau ua kom tiav, sib npaug ntawm cov khoom siv hluav taws xob, kev ua haujlwm ruaj khov, ib puag ncig durability, thiab kev lag luam muaj txiaj ntsig.
kev txiav txim siab xaiv cov khoom
- Conductivity ntawm tooj liab
Hluav taws xob conductivity yog ib qho kev ntsuas kev ua haujlwm tseem ceeb rau cov khoom siv tooj liab. Thaum xaiv tubing rau daim ntawv thov kav hlau txais xov, qhov conductivity ntawm tooj liab ncaj qha txiav txim siab lub teeb liab kis tau tus mob. Cov tooj liab ntshiab muaj qhov ua tau zoo tshaj plaws ntawm cov hlau sib xws, ua rau cov tooj liab siab ntshiab (Red Copper) thiab cov qauv tooj liab cov kev xaiv tseem ceeb tshaj plaws rau cov kav hlau txais xov reflector tubing. Cov ntaub ntawv no ua ke cov khoom siv hluav taws xob siab nrog qhov tsis muaj zog, yog li ua kom cov teeb liab tawm sai thiab txhim khu kev qha.
- Mechanical Strength ntawm tooj liab
Kav hlau txais xov tooj liab tubing yog qhov sib txawv ntawm cov neeg kho tshuab kev ntxhov siab thaum lub sijhawm ua haujlwm ib txwm ua, ua rau lub zog siv tshuab yog qhov tseem ceeb hauv kev xaiv cov khoom. Ob leeg ntshiab tooj liab thiab tooj dag muaj zog txaus rau feem ntau cov kav hlau txais xov daim ntawv thov; Txawm li cas los xij, lawv cov khoom siv kho tshuab tsis zoo ib yam. Thaum txiav txim siab cov khoom tsim nyog tshaj plaws, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov ntev, geometry, thiab kev ua haujlwm ntawm lub kav hlau txais xov, vim tias cov xwm txheej no cuam tshuam ncaj qha rau qhov yuav tsum tau muaj peev xwm thauj khoom thiab kev ua haujlwm ntev.
- Corrosion Resistance ntawm cov khoom siv tooj liab
Kav hlau txais xov tooj liab tubing feem ntau ntsia tau rau hauv qhov chaw sab nraum zoov, qhov twg nws raug los nag, av noo, thiab ntsev tsuag. Raws li qhov tshwm sim, cov khoom xaiv yuav tsum muaj qhov muaj zog tiv thaiv corrosion kom ntseeg tau lub sijhawm ntev. Piv nrog rau cov tooj liab ntshiab, tooj dag qhia tau hais tias muaj kev tiv thaiv zoo rau ib puag ncig corrosion, ua rau nws muaj kev ntseeg siab dua rau kev siv hauv qhov hnyav lossis cov ntug hiav txwv, qhov kev pab cuam lub neej ntev yog qhov tseem ceeb.
- Kev txiav txim siab nqi
Tus nqi yog qhov tseem ceeb hauv kev xaiv cov khoom siv tooj liab rau cov kav hlau txais xov tubing. Cov qib tooj liab sib txawv thiab cov alloys hais kom sib txawv ntawm tus nqi, thiab qhov kev xaiv zoo tshaj plaws yuav tsum sib npaug cov kev xav tau ntawm kev lag luam. Tsis tas li ntawd, nws yog ib qho tseem ceeb uas yuav tsum xav txog tag nrho cov nqi ntawm cov tswv cuab- suav nrog cov kev pab cuam lub neej thiab cov nqi kho mob - tsis yog tsom rau cov nqi khoom ua ntej xwb. Xaiv cov khoom siv ruaj khov, ruaj khov feem ntau ua pov thawj tias muaj txiaj ntsig zoo dua rau lub sijhawm ntev.
Yog li ntawd, kev xaiv cov khoom siv tooj liab rau cov kav hlau txais xov tubing xav tau kev ntsuam xyuas dav dav uas sib npaug hluav taws xob conductivity, txhua yam muaj zog, corrosion kuj, thiab nqi. Txawm hais tias ob qho tib si ntshiab tooj liab thiab tooj dag feem ntau ua haujlwm hauv daim ntawv thov no, qhov kev xaiv zoo tshaj plaws yog nyob ntawm qhov kev ua haujlwm tshwj xeeb thiab ib puag ncig ntawm cov phaj phaj. Kev xaiv cov khoom muaj txiaj ntsig zoo, paub zoo kom ntseeg tau tias tus kav hlau txais xov reflector muab hluav taws xob ua tau zoo thaum ua tiav lub neej ntev kev pab cuam.
Vim li cas tooj liab ntshiab tsis haum rau Telescopic kav hlau txais xov?
Txawm hais tias cov tooj liab ntshiab (tseem hu ua electrolytic tooj liab) muaj cov khoom siv hluav taws xob zoo heev, nws lub cev thiab cov khoom siv hluav taws xob ncaj qha cuam tshuam qhov tseem ceeb ntawm cov kav hlau txais xov telescopic, ua rau nws siv tsis tau rau feem ntau cov ntawv thov hauv ntiaj teb.
Lub hauv paus tsis sib haum xeeb: Hluav taws xob vs. Mechanical Performance
Tus nqi tseem ceeb ntawm lub kav hlau txais xov telescopic yog nyob rau hauv nws lub peev xwm los txuas ntxiv thiab thim rov qab thiab du. Qhov no xav kom cov khoom muaj zog txaus, hardness, thiab hnav tsis kam. Ntshiab tooj liab poob luv luv hauv cov chaw tseem ceeb no:
- Tsis txaus hardness thiab lub zog - Ntshiab tooj liab kuj yog mos. Hauv cov kav hlau txais xov loj lossis txhawb nqa tus kheej, nws nyiam khoov lossis deform nyob rau hauv nws tus kheej qhov hnyav lossis sab nraud quab yuam.
- Kev hnav tsis zoo - Cov ntu ntawm lub kav hlau txais xov telescopic rub tawm ib leeg tsis tu ncua. Copper tsis tshua muaj hnav tsis kam ua rau muaj kev puas tsuaj ntxov ntxov, ua rau muaj kev sib cuag tsis zoo los yog zawv zawg zawv zawg zog dhau sijhawm.
- Tsawg qaug zog tsis kam - Rov ua dua qhov txuas ntxiv / thim rov qab ua rau cov khoom qaug zog. Cov tooj liab ua tau zoo dua li tooj dag hauv qhov no, ua rau muaj kev pheej hmoo ntawm kev tawg lossis tawg tom qab siv mus ntev.
Hauv luv luv, ntshiab tooj liab zoo li "tus kws tshaj lij ib qho" - zoo heev hauv kev ua haujlwm hluav taws xob tab sis tsis muaj "lub cev muaj zog" los tswj cov kev xav tau ntawm cov khoom siv kho tshuab uas xav tau los ntawm telescopic antennas.

Vim li cas tooj dag yog qhov kev xaiv zoo dua
Brass (copper-zinc alloy) ua lag luam ib feem ntawm hluav taws xob conductivity rau aKev txhim kho zoo heev hauv cov khoom siv kho tshuablos ntawm kev sib ntxiv ntawm zinc. Rau telescopic kav hlau txais xov, qhov kev lag luam tawm no zoo tsim nyog nws:
- Structural zog - tooj dag muab lub zog txaus thiab hardness los txhawb lub kav hlau txais xov qauv, tiv thaiv sab nraud quab yuam, thiab tswj kev ncaj.
- Hnav tsis kam thiab ua haujlwm ntev - Nws cov hardness siab dua thiab puas ua rau nws tuaj yeem tiv taus ntau txhiab lub voj voog telescoping thaum ua kom zoo, ua haujlwm ntev.
- Kev ntseeg tau thiab ruaj khov - tooj dag muaj cov coefficient ntawm thermal expansion ze rau ntawm cov neeg xyuas pib sab hauv (piv txwv li, tooj liab lossis hlau), ua kom muaj kev sib cuag zoo thiab txhim khu kev qha hauv qhov sib txawv ntawm qhov kub thiab txias.
- Yooj yim ntawm fabrication - Brass muaj superior machinability, ua kom yooj yim los tsim cov meej, nested seem xav tau rau telescopic designs.
Cov ntsiab lus
Ntshiab tooj liab (Red Copper), nrog nws cov khoom siv hluav taws xob zoo, yog qhov kev xaiv zoo tshaj plaws rau cov kav hlau txais xov, RF cables, thiab lwm yam kev siv zoo li qub. Txawm li cas los xij, rau cov kav hlau txais xov telescopic uas xav tau rov ua dua txhua yam kev txav mus los thiab kev ntxhov siab, nws cov khoom siv tsis muaj zog yog qhov teeb meem tseem ceeb.
Yog li ntawd, tooj dag - nrog rau nws qhov zoo tshaj qhov sib npaug ntawm lub zog, hardness, hnav tsis kam, thiab tus nqi - tseem yog cov khoom siv tsis txaus ntseeg ntawm kev xaiv rau telescopic kav hlau txais xov.
