Kev sib txuas lus cable hauv qhov kis tau cov cim qhia ntau zaus, cov teeb meem ntawm cov tawv nqaij sib kis tau ntau dua thiab hnyav dua. Lub npe hu ua tawv nqaij yog hais txog qhov kev sib kis ntawm cov cim raws cov teeb liab sab nraud
Tshwj xeeb, nrog tus nqi hauv ntiaj teb ntawm tooj liab sooling thiab tooj liab cov hlau los hloov cov hlau thiab cable kev lag luam, tab sis kuj rau kev siv cable nrog kev siv cov chaw ua lag luam loj.
Tab sis cov hlau hauv lub tooj plating tooj liab, vim yog cov kev kho mob me me, cov khoom siv sib xyaw ua ke, cov khoom siv sib xyaw ua ke, cov khoom siv khib nyiab, kom cov khoom tsim khoom tsim nce. Yog li ntawd, nws yog qhov tseem ceeb tshaj plaws kom paub meej qhov zoo ntawm txheej. Cov ntawv no tsuas yog tham txog cov ntsiab cai thiab cov txheej txheem rau kev tsim cov tooj liab-clad hlau hlau los ntawm cov teeb meem ua kom muaj teeb meem thiab txoj kev daws teeb meem. 1 tooj liab-clad steel hlau plating txheej txheem thiab nws ua
1. 1 Ua ntej Kev Kho Mob Ntawm Cov Hlau
Ua ntej, cov hlau yog raus hauv alkaline thiab pickling tov thiab muaj qee cov voltage yog thov rau cov hlau (anode) thiab lub phaj (catode), anode precipitates ntau npaum li cas ntawm cov pa. Lub luag haujlwm tseem ceeb ntawm cov gases no yog: ib qho, ua phem rau cov roj ntawm cov hlau hlau, ua kom muaj zog ntawm cov roj ntsha thiab cov roj ntsha ntawm cov roj thiab roj; Thib ob, vim hais tias ntawm cov npuas me me txuas nrog cov roj av, yog li ntawd, cov pa roj hmab ntau ntxiv, yog li ntawd, nws tsis yooj yim los ua hydrogen embrittlement ntawm anode, yog li ntawd kev plating zoo tuaj yeem tau txais.
1. 2 plating ntawm cov hlau
Ua ntej, cov hlau yog ua ntej kho thiab ua ntej nrog Nickel los ntawm kev raus nws hauv cov qauv siv rau cov hlau (catrode) thiab phaj tooj liab (anode). Ntawm anode, lub tooj liab phaj poob hluav taws xob thiab cov khoom tooj dawb los tooj liab ions hauv electrolytic (plating) da dej:
CU - 2E → CU2 +
Nyob rau hauv lub cathode, cov hlau xaim hluav taws xob yog electronised thiab tooj liab ions yog muab tso rau ntawm cov hlau-clad hlau hlau:
Cu2 + + 2e → Cu
Cu2 + + e → CU +
CU + + E → CU
2h + + 2e → H2
Thaum tus nqi ntawm cov kua qaub nyob rau hauv cov plating daws yog qhov tsis txaus, cuppous sulphate yog yooj yim hydrolysed los tsim cov tshuaj pleev kom zoo. Lub cuprous oxide yog cuab hauv cov plating txheej, ua kom nws xoob. Cu2 So4 + H2O [CU2O + H2 So4
I. Cov ntsiab lus tseem ceeb
Sab nraum zoov cov kab hluav taws xob feem ntau muaj cov khoom liab qab, xoob raj, cov khoom siv dej, ntxiv dag zog rau cov khoom, thiab riam. Lawv tuaj nyob rau hauv ntau yam qauv xws li Central raj tsim, txheej txheej teeb, thiab cov qauv pob txha.
Liab qab Fibers xa mus rau thawj kho qhov muag zoo nkauj nrog txoj kab uas hla ntawm 250 micrometers. Lawv feem ntau suav nrog cov txheej txheem tseem ceeb, cladding txheej, thiab txheej txheej txheej. Txawv sib txawv ntawm cov poj niam liab qab muaj cov txheej txheem sib txawv ntau thiab tsawg. Piv txwv li, ib hom-hom OS2 fibers feem ntau yog 9 micrometers, hul 5 / om3 / Om3 / Om4 / Om4 / Om4 / om1 Fibers yog 62.5 micrometers. Cov poj niam liab qab yog feem ntau xim-cim rau kev sib txawv ntawm ntau cov tub ntxhais.
Cov leeg xoob feem ntau yog ua los ntawm high-zog engineering yas PBT thiab siv kom haum rau cov ncej liab qab. Lawv muab kev tiv thaiv thiab muaj cov roj uas thaiv cov dej uas thaiv cov dej los tiv thaiv cov dej ingress uas tuaj yeem ua rau cov fibers puas. Cov gel kuj ua raws li kev ua tsis taus kom tiv thaiv kev puas tsuaj fiber ntau los ntawm kev cuam tshuam. Kev tsim qauv tsim ntawm cov xoob xoob yog qhov tseem ceeb los xyuas kom muaj fiber ntau dhau.
Cov ntaub ntawv thaiv dej muaj xws li cable dej-thaiv roj, dej-thaiv cov xov paj, lossis dej thaiv cov hmoov. Txhawm rau txhim kho kev txhim kho lub cable tag nrho cov dej thaiv cov dej muaj peev xwm, txoj kev ua kom zoo tshaj plaws yog siv cov roj teeb hluav taws xob.
Ntxiv dag zog rau cov ntsiab lus tuaj hauv hom xim hlau thiab tsis yog xim hlau. Nws yog xim hlau feem ntau yog ua los ntawm phospholated steel hlau, txhuas tapes, lossis cov hlau tapes. Cov khoom tsis yog xim hlau yog feem ntau ua los ntawm Frp cov ntaub ntawv. Tsis hais txog cov khoom siv, cov ntsiab no yuav tsum muab cov kev tsim nyog ntawm lub zog kom tau raws li cov qauv kev xav tau, suav nrog nro, khoov, thiab sib ntswg.
Sab nraud sheaths yuav tsum xav txog kev siv kev pab, suav nrog kev lim dej, UV tsis kam, thiab huab cua tsis kam. Yog li no, cov khoom siv dub yog siv, raws li nws cov khoom siv thiab tshuaj lom neeg kom haum rau sab nraum zoov.
2 Qhov ua rau muaj cov teeb meem zoo hauv kev plating plating txheej txheem thiab lawv cov kev daws teeb meem
2. 1 Tus cawv ntawm kev kho mob ua ntej ntawm cov hlau ntawm cov plating txheej ua ntej ntawm cov xaim-clad steel hlau los ntawm electroplating. Yog tias cov roj thiab oxide zaj duab xis nyob rau saum npoo ntawm cov hlau tsis raug tshem tawm tag nrho, tom qab ntawd yuav ua rau lub ntsiab tooj liab plating txheej poob tawm. Nws yog vim li no tseem ceeb kom ua kom lub qhov muag ntawm kev pom zoo ntawm alkaline thiab pickling kua, tam sim no yog ib txwm muaj, thiab yog tias lawv tsis raug muab kho kom sai. Cov teeb meem zoo hauv kev kho ua ntej ntawm cov hlau xaim thiab lawv cov kev daws teeb meem yog qhia hauv rooj
2. 2 Qhov kev ruaj ntseg ntawm cov tshuaj muaj hnub nyoog ua ntej tsis ncaj qha rau cov txheej txheem ua ntej plating Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau txheeb xyuas thiab kho cov lus sib xyaw ntawm cov kab ke ua ntej npib tsib xee thiab tsis muaj kuab lom.
2.3 Cov cawv ntawm lub ntsiab plating daws cov plating txheej cov plating cov kev daws teeb meem thiab sulfuric acid li ob ntu, cov lus sib piv ncaj qha rau kev txiav txim siab ncaj qha ntawm cov plating txheej. Yog hais tias lub concentration tooj liab sulphate yog qhov siab dhau, tooj liab sulphate muaju yuav precipitated yuav precipitated; Yog hais tias lub concentration tooj liab sulphate yog tsawg dhau, cov hlau yuav yooj yim scorched thiab lub plating efficiency yuav cuam tshuam. Sulfuric acid tuaj yeem txhim kho cov hluav taws xob hluav taws xob, kom tiv thaiv kev sib xyaw ntawm cov pob zeb hluav taws xob (kom tiv thaiv qhov hluav taws xob ceev rau hauv cov roj hluav taws xob) Kev ruaj khov ntawm cov plating daws, tab sis kuj tseem txo cov anodic polarization, uas yog conducive rau cov kev tsis sib xws ntawm anode. Txawm li cas los xij, nws yuav tsum tau sau tseg tias qhov siab sulfuric acid cov ntsiab lus yuav txo cov solubility ntawm tooj liab sulphate. Thaum cov sulfuric acid cov ntsiab lus nyob rau hauv cov kev daws teeb meem yog tsis txaus, tooj liab sulpous oxide thiab sau cov txheej txheej ua kom tsaus thiab xoob; Thaum muaj ib qho dhau ntawm cov sulfuric acid nyob rau hauv cov kev daws teeb meem thiab cov ntsev tsis txaus, kom cov nplaim dej ntawm cov plating txheej pom kev lom zem. Phosphorus tooj liab phaj phosphorus cov ntsiab lus tseem muaj qhov cuam tshuam tseem ceeb ntawm cov tooj liab, yog li ua kom muaj zog nyob hauv cov phiaj xwm liab; Yog tias cov ntsiab lus phosphorus ntawm ntau tshaj 0. 1%, nws yuav cuam tshuam rau kev sib cais ntawm tooj liab anode, yog li cov ntsiab lus ntawm cov kev daws teeb meem tsawg dua, thiab tsim ntau ntawm cov av nkos anode. Tsis tas li ntawd, lub phaj tooj liab yuav tsum tau yaug tsis tu ncua los tiv thaiv lub anim sludge los ntawm puruting cov platness thiab ua rau ntxhib thiab burrs nyob rau hauv lub plating txheej.

Los ntawm kev ua cov txheej txheem saum toj no, cov nplaum thiab cov khoom lag luam txuas ntxiv yog qhov zoo, qhov zoo yog qhov ruaj khov thiab kev ua tau zoo heev. Txawm li cas los xij, nyob rau hauv cov txheej txheem ntau lawm, muaj ntau ntau yam cuam tshuam rau qhov zoo ntawm txheej plating, ib zaug qhov teeb meem tau pom, yuav tsum tau raug ntsuas kom daws tau nws.
