Feem ntau, cov khoom siv kho qhov muag thiab cov kab hluav taws xob tau muab tso rau hauv qhov chaw ntub dej thiab tsaus ntuj. Yog tias lub cable puas lawm, cov dej noo yuav nkag mus rau hauv lub cable raws li qhov chaw puas thiab cuam tshuam rau cable. Dej tuaj yeem hloov pauv qhov capacitance hauv tooj liab cables, txo cov teeb liab zog. Nws yuav ua rau muaj kev kub ntxhov ntau dhau ntawm cov khoom siv kho qhov muag hauv cov khoom siv kho qhov muag, uas yuav cuam tshuam rau kev sib kis ntawm lub teeb. Yog li ntawd, sab nraud ntawm cov khoom siv kho qhov muag yuav muab qhwv nrog cov khoom thaiv dej. Dej thaiv cov xov paj thiab cov hlua thaiv dej yog feem ntau siv cov khoom thaiv dej. Daim ntawv no yuav kawm txog cov khoom ntawm ob, txheeb xyuas qhov zoo sib xws thiab qhov sib txawv ntawm lawv cov txheej txheem tsim khoom, thiab muab cov ntaub ntawv siv rau kev xaiv cov khoom siv dej thaiv.
1.Kev sib piv ntawm cov dej thaiv cov xov paj thiab cov hlua thaiv dej
(1) Cov khoom ntawm cov dej thaiv cov xov paj
Tom qab kev ntsuam xyuas cov ntsiab lus ntawm cov dej thiab cov txheej txheem ziab, qhov nqus dej ntawm cov dej thaiv cov xov paj yog 48g / g, lub zog tensile yog 110.5N, qhov tawg elongation yog 15.1%, thiab cov ntsiab lus noo noo yog 6%. Kev ua tau zoo ntawm cov dej thaiv cov xov paj ua tau raws li cov qauv tsim ntawm lub cable, thiab cov txheej txheem spinning kuj ua tau.
(2) Kev ua haujlwm ntawm cov dej thaiv cov hlua
Dej thaiv txoj hlua feem ntau yog cov dej thaiv cov khoom siv uas xav tau rau cov cables tshwj xeeb. Nws yog tsim los ntawm dipping, bonding thiab ziab ntawm polyester fibers. Tom qab cov fiber ntau yog tag nrho combed, nws muaj longitudinal zog, lub teeb yuag, nyias thickness, siab tensile zog, zoo rwb thaiv tsev kev ua tau zoo, tsis tshua muaj elasticity, thiab tsis muaj corrosion.
(3) Lub ntsiab khoom siv tes ua tshuab ntawm txhua tus txheej txheem
Rau cov dej thaiv cov xov paj, daim npav yog cov txheej txheem tseem ceeb tshaj plaws, thiab cov av noo nyob hauv qhov kev ua haujlwm no yuav tsum qis dua 50%. SAF fiber ntau thiab polyester yuav tsum tau tov nyob rau hauv ib qho kev faib ua feem thiab combed tib lub sij hawm, yog li ntawd lub SAF fiber thaum lub sij hawm daim carding txheej txheem yuav sib npaug zos rau ntawm lub web polyester fiber, thiab tsim ib tug network qauv ua ke nrog lub polyester kom txo tau nws. ntog. Nyob rau hauv kev sib piv, qhov yuav tsum tau ntawm cov dej thaiv cov hlua nyob rau theem no zoo ib yam li cov dej thaiv cov xov paj, thiab cov ntaub ntawv poob yuav tsum raug txo kom ntau li ntau tau. Tom qab scientific kev faib ua feem configuration, nws nteg ib tug zoo tsim lub hauv paus rau cov dej thaiv hlua nyob rau hauv tus txheej txheem ntawm thinning.
Rau cov txheej txheem roving, raws li cov txheej txheem kawg, cov dej thaiv cov xov paj yog tsim los ntawm cov txheej txheem no. Nws yuav tsum ua raws li kev ceev ceev, me me, qhov deb loj, thiab qis twist. Qhov kev tswj hwm tag nrho ntawm cov qauv sib piv thiab lub hauv paus nyhav ntawm txhua tus txheej txheem yog tias cov xov paj ntom ntawm cov dej zaum kawg thaiv cov xov paj yog 220Tex. Rau cov dej thaiv txoj hlua, qhov tseem ceeb ntawm kev rov ua haujlwm tsis tseem ceeb npaum li cov xov thaiv dej. Cov txheej txheem no feem ntau yog nyob rau hauv qhov kawg ua tiav ntawm cov dej thaiv cov hlua, thiab kev kho qhov tob ntawm cov kev sib txuas uas tsis nyob hauv qhov chaw hauv cov txheej txheem tsim khoom kom ntseeg tau qhov zoo ntawm cov dej thaiv cov hlua.
(4) Kev sib piv ntawm cov dej-absorbing fibers hauv txhua txoj kev
Rau cov dej thaiv cov xov paj, cov ntsiab lus ntawm SAF fibers maj mam txo nrog qhov nce ntawm cov txheej txheem. Nrog rau kev nce qib ntawm txhua tus txheej txheem, qhov kev txo qis yog qhov loj, thiab qhov kev txo qis kuj txawv rau cov txheej txheem sib txawv. Ntawm lawv, kev puas tsuaj hauv cov txheej txheem carding yog qhov loj tshaj plaws. Tom qab kev sim kev tshawb fawb, txawm tias nyob rau hauv cov ntaub ntawv ntawm ib qho kev pom zoo, txoj kev nyiam ua rau lub suab ntawm SAF fibers tsis tuaj yeem zam tau thiab tsis tuaj yeem tshem tawm. Piv nrog rau cov dej thaiv cov xov paj, cov fiber ntau shedding ntawm cov dej thaiv cov hlua yog qhov zoo dua, thiab qhov poob tuaj yeem txo qis hauv txhua txoj kev tsim khoom. Nrog rau kev sib sib zog nqus ntawm cov txheej txheem, qhov teeb meem ntawm fiber ntau tau txhim kho.
2. Kev siv cov dej thaiv cov xov paj thiab cov dej thaiv cov hlua hauv cable thiab optical cable
Nrog rau kev txhim kho thev naus laus zis hauv xyoo tas los no, cov xov paj thaiv dej thiab dej thaiv cov hlua feem ntau yog siv los ua cov khoom siv sab hauv ntawm cov khoom siv kho qhov muag. Feem ntau hais lus, peb cov dej thaiv cov yarns los yog dej thaiv cov hlua tau ntim rau hauv lub cable, ib qho ntawm feem ntau muab tso rau ntawm lub hauv paus kev txhawb nqa kom ntseeg tau tias kev ruaj ntseg ntawm cov cable, thiab ob lub xov thaiv dej feem ntau muab tso rau sab nraum cov tub ntxhais cable los xyuas kom meej tias. cov dej thaiv cov nyhuv tuaj yeem ua tiav qhov zoo tshaj plaws. Kev siv cov dej thaiv cov xov paj thiab dej thaiv cov hlua yuav hloov tau qhov kev ua tau zoo ntawm cov khoom siv kho qhov muag.
Rau cov dej thaiv kev ua tau zoo, cov dej thaiv kev ua haujlwm ntawm cov dej thaiv cov xov paj yuav tsum tau nthuav dav ntxiv, uas tuaj yeem txo qhov kev ncua deb ntawm cov tub ntxhais cable thiab lub tsho. Nws ua rau cov dej thaiv cov nyhuv ntawm lub cable zoo dua.
Nyob rau hauv cov nqe lus ntawm txhua yam khoom, lub tensile zog, compressive zog thiab dabtsi yog khoov zog ntawm lub optical cable yog zoo heev tom qab sau cov dej thaiv cov xov paj thiab cov dej thaiv cov hlua. Rau qhov kub thiab txias kev ua tau zoo ntawm cov kab hluav taws xob kho qhov muag, qhov kho qhov muag cable tom qab sau cov dej thaiv cov xov paj thiab cov hlua thaiv dej tsis muaj qhov pom tseeb ntxiv attenuation. Rau qhov kho qhov muag cable sheath, cov dej thaiv cov xov paj thiab cov dej thaiv cov hlua yog siv los sau cov kab hluav taws xob kho qhov muag thaum lub sijhawm tsim, kom cov txheej txheem txuas ntxiv ntawm cov sheath tsis cuam tshuam rau txhua txoj hauv kev, thiab kev ncaj ncees ntawm optical cable sheath ntawm no. qauv yog siab dua. Nws tuaj yeem pom los ntawm kev txheeb xyuas saum toj no tias cov fiber ntau optic cable ntim nrog dej thaiv cov xov paj thiab cov hlua thaiv dej yog qhov yooj yim rau kev ua, muaj kev ua haujlwm ntau dua, tsis muaj kuab paug ib puag ncig, zoo dua dej thaiv cov nyhuv thiab kev ntseeg siab dua.
3. Cov ntsiab lus
Tom qab kev sib piv cov kev tshawb fawb ntawm cov txheej txheem ntawm cov dej thaiv cov xov paj thiab cov dej thaiv cov hlua, peb muaj kev nkag siab tob txog qhov kev ua tau zoo ntawm ob, thiab muaj kev nkag siab tob txog kev ceev faj hauv cov txheej txheem tsim khoom. Nyob rau hauv daim ntawv thov txheej txheem, tsim nyog xaiv yuav ua tau raws li cov yam ntxwv ntawm lub optical cable thiab ntau lawm txoj kev, thiaj li mus txhim kho cov dej thaiv kev ua tau zoo, xyuas kom meej qhov zoo ntawm optical cable thiab txhim kho kev ruaj ntseg ntawm hluav taws xob noj.
