Lead Wire Material Xaiv - Kev txiav txim siab tseem ceeb rau kev cia siab rau lub rhaub

Cov coj uas txuas lub tshuab cua sov rau lub zog yog qhov ua rau nws ua haujlwm. Qhov no yog cov lus tseeb hauv ntau lub sijhawm. Txawm hais tias lub tshuab cua sov ua kom zoo thiab txhim kho zoo, nws tseem yuav ua tsis tau yog tias cov hlau lead tsis tuaj yeem ua haujlwm ntawm ib puag ncig uas lawv nyob hauv. Tab sis thaj chaw nyob ib ncig ntawm qhov kev txiav tawm kawg yuav nyuaj li qhov chaw kub nws tus kheej.

PVC, Teflon (PTFE), fiberglass, thiab ceramic yog cov khoom siv nrov tshaj plaws siv los thaiv cov hlau lead. PVC yog qhov pheej yig tshaj plaws thiab hloov tau yooj yim, tab sis nws tsuas tuaj yeem tswj qhov kub txog li 105 degree. Teflon tuaj yeem tiv taus kub txog 200℃thiab tiv taus cov tshuaj. Fiberglass rwb thaiv tsev tuaj yeem tswj qhov kub txog li 450 degree, txawm tias nws tsis hloov pauv thiab tuaj yeem nqus dej. Ceramic-cov khoom siv hluav taws xob muaj peev xwm tswj tau qhov kub siab tshaj plaws, feem ntau yog siab tshaj 650 degree, tab sis lawv tawv thiab tawg yooj yim. Xaiv qhov rwb thaiv tsev tsis raug rau qhov kub thiab txias ntawm qhov kawg ntawm kab yuav ua rau nws ua tsis tiav thaum ntxov.

Cov khoom siv rau tus neeg xyuas pib yog qhov tseem ceeb. Feem ntau, tus qauv tooj liab ua haujlwm zoo yog tias qhov kawg nyob txias. Tab sis thaum qhov chaw tawm ntawm cov hlau lead kub dhau, tooj liab yuav oxidise thiab tsis ua hluav taws xob. Nickel los yog npib tsib xee-plated tooj liab ua tsis oxidise yooj yim thaum kub dua. Ntshiab nickel conductors yog siv nyob rau hauv cov xwm txheej hnyav heev. Nickel leads yog tus qauv hauv swaged- hauv kev tsim kho, qhov twg cov hlau lead raug kaw hauv lub rhaub. Qhov no yog vim lawv muaj peev xwm tswj tau qhov kub thiab txias hauv cheeb tsam txiav.

Qhov ntev thiab ntsuas ntawm cov hlau lead kuj muaj qhov cuam tshuam rau nws ua haujlwm zoo npaum li cas. Yog tias cov hlau lead ntev ntev, qhov hluav taws xob tuaj yeem poob, uas txhais tau hais tias tsawg zog xa mus rau lub rhaub. Cov txhuas uas luv luv yuav nyob rau hauv qhov nro tas li, uas yuav ua rau muaj kev ntxhov siab rau sab hauv crimp. Lub ntsuas yuav tsum muaj peev xwm tswj tau qhov tam sim no. Ib qho yuam kev feem ntau yog siv cov hlau lead uas nyias dhau rau lub rhaub lub wattage, uas ua rau cov coj lawv tus kheej kub. Qhov kub nce nyob rau hauv undersized ua rau nce lub thermal kev nyuaj siab ntawm qhov kev txiav, uas ua rau kom qhov tawg ntawm rwb thaiv tsev.

Lead qaug zog yog ib qho kev txhawj xeeb loj rau cov ntawv thov uas txav los yog vibrate ntau heev. Stranded conductors tsis tshua muaj nkees dua li cov xaim hlau. Tus naj npawb ntawm cov strands yog ib qho tseem ceeb: ntau cov strands sib npaug ntau dua thiab lub neej ntev dua thaum khoov dua thiab ntau dua. Qee qhov siab -flex leads muaj ntau pua ntawm nyias strands. Ntxiv ib qho kev hloov pauv hloov mus rau lub rhaub lub cev kom tsis txhob muaj kev ntxhov siab los ntawm kev tsim ntawm qhov chaw crimp. Stainless hlau overbraid los yog hloov tau yooj yim conduit khaws cov khoom ntawm kev txiav los yog hnav.

Cov dej noo yog lwm yam uas tuaj yeem ua rau cov hlau lead puas. Nyob rau hauv qhov chaw uas muaj av noo ntau los yog qhov chaw uas cov khoom raug ntxuav, noo noo tuaj yeem nkag los ntawm kev rwb thaiv tsev thiab mus rau qhov kev txiav tawm. Fiberglass rwb thaiv tsev yog qhov tsis zoo rau qhov no vim nws ua zoo li daim txhuam cev. Teflon rwb thaiv tsev zoo dua ntawm kev ua kom tsis txhob ya raws, tab sis yog tias nws tsis raug kaw kom zoo, cov dej tseem tuaj yeem nkag los ntawm tus neeg xyuas pib. Thaum kawg ntawm qhov kev txiav tawm, cua sov-shrink tubing lossis molded rubber khau boots kom tsis txhob ya raws.

Kev paub dhau los tau pom tias lub tshuab cua sov tsis ua haujlwm feem ntau yuam kev rau cov hlau lead tsis ua haujlwm. Lub tshuab cua sov tuaj yeem kuaj qhib, tab sis qhov tawg yog tiag tiag hauv cov hlau lead, tsis yog cov hlau tsis kam. Thaum koj ntsuas qhov txuas ntxiv, khoov cov kev coj ua qhia tau hais tias muaj kev tawg uas tshwm sim ib ntus. Yog tias lub rhaub dej tawg thiab cov hlau lead pib hloov xim, ua nkig, lossis tawg, cov hlau lead yog qhov txuas tsis muaj zog. Txhawm rau kom tsis txhob tshwm sim dua, koj tuaj yeem hloov mus rau rwb thaiv tsev uas tuaj yeem tswj tau qhov kub thiab txias dua lossis tus neeg xyuas pib uas hloov tau yooj yim dua.

Rau kev siv tseem ceeb, nws yog qhov ntse los muab cov kev coj ua uas zoo tshaj qhov xav tau. Cov hlau lead uas tuaj yeem tswj tau 200℃hauv 150℃huab cua yog txhim khu kev qha. Cov hlau lead uas tuaj yeem tswj tau 200℃hauv 190℃ib puag ncig yog nyob ntawm ntug. Nws tsis raug nqi ntau npaum li cas los hloov cov khoom siv hluav taws xob los yog cov khoom siv hluav taws xob, thiab cov sij hawm poob tau yooj yim ua rau. Cov hlau lead yog qhov ua kom lub cua sov mus. Xaiv lawv ua tib zoo ua kom lub neej muaj kev nyab xeeb.
