Thaum nrhiav qhov zoo tshaj plaws cables thiab xaim, xaiv txoj cai sheathing cov khoom siv yog qhov tseem ceeb. Lub ntsej muag sab nraud muaj ntau lub luag haujlwm kom ntseeg tau tias lub durability, kev nyab xeeb thiab kev ua tau zoo ntawm cable lossis hlau. Nws tsis yog qhov tsis yooj yim kom muaj kev txiav txim siab ntawm polyurethane (pur) thiabpolyvinyl chloride (PVC)Cov. Hauv tsab xov xwm no, koj yuav kawm txog kev ua yeeb yam sib txawv ntawm ob cov ntaub ntawv thiab cov ntawv thov uas txhua cov khoom siv tau zoo tshaj.
Sheathing qauv thiab muaj nuj nqi hauv cov xaim thiab xaim
Ib lub hnab riam (tseem hu ua lub ntsej muag sib dhos Cov hnab riam los tiv thaiv cov cable cov neeg coj thiab lwm cov txheej txheem txheej txheem los ntawm lwm cov khoom sab nraud xws li cua sov, ntub, ntub dej thiab siv tshuab. Nws kuj tseem tuaj yeem txhim kho cov duab thiab daim ntawv ntawm cov neeg saib xyuas tus neeg taug kev, nrog rau txheej txheem tiv thaiv (yog tias muaj kev cuam tshuam), yog li tsis tshua muaj kev cuam tshuam nrog cable electromagnetic (EMC). Qhov no yog qhov tseem ceeb kom muaj kev kis tau zoo sib xws ntawm lub zog, teeb liab, lossis cov ntaub ntawv hauv cable lossis xaim. Sheathing kuj tseem ua lub luag haujlwm tseem ceeb hauv lub txiaj ntsig ntawm cov cable thiab xov hlau.
Xaiv txoj cai sheathing cov khoom yog qhov tseem ceeb los txiav txim siab qhov zoo tshaj plaws cable rau txhua daim ntawv thov. Yog li ntawd, nws yog ib qho tseem ceeb kom paub tseeb tias lub hom phiaj lub cable lossis hlau yuav tsum ua haujlwm thiab yuav tsum tau ua tiav.
Cov khoom siv sheathing tshaj plaws
Polyurethane (pur) thiab polyvinyl chloride (PVC) yog ob feem ntau siv cov ntaub ntawv sheathing rau cov xaim thiab xaim. Visually, tsis muaj qhov sib txawv ntawm cov ntaub ntawv no, tab sis lawv nthuav tawm cov khoom sib txawv uas ua rau lawv haum rau cov ntawv thov sib txawv. Ib qho ntxiv, ob peb lwm cov ntaub ntawv tuaj yeem siv ua cov ntaub ntawv sheathing, suav nrog kev lag luam roj hmab, thermoplastic elastomers (TPE), thiab cov khoom siv yas tshwj xeeb. Txawm li cas los xij, txij li lawv tsis tshua muaj ntau dua li pur thiab pvc, peb yuav tsuas muab piv ob yav tom ntej.
Pur - qhov tseem ceeb tshaj plaws
Polyurethane (lossis pur) yog hais txog ib pawg ntawm plastics tsim nyob rau xyoo 1930. Nws yog tsim los ntawm cov tshuaj lom neeg hu ua ntxiv polymerization. Cov khoom siv raw feem ntau yog roj av, tab sis cov khoom cog ntoo xws li cov qos yaj ywm, pob kws lossis cov beets qab zib tseem tuaj yeem siv tau hauv nws cov khoom lag luam. Polyurethane yog ib thermoplastic elastomer. Qhov no txhais tau tias lawv hloov tau thaum rhuab, tab sis tuaj yeem rov qab mus rau lawv cov qauv qub thaum muaj cua sov.
Polyurethane muaj tshwj xeeb tshaj yog cov khoom siv zoo. Cov khoom siv tau hnav zoo heev, txiav kev tiv thaiv thiab lub kua muag tiv taus, thiab tseem yoog tau yooj yim txawm tias kub tsawg. Qhov no ua rau pur tshwj xeeb haum rau cov ntawv thov uas xav tau cov lus tsa suab thiab khoov yuav tsum muaj, xws li cov saw hlau. Hauv cov ntawv thov loj, cables nrog pur sheathing tuaj yeem tiv taus ntau lab ntawm cov kauj vab uas tsis muaj teeb meem. Pur tseem muaj zog tiv taus cov roj, cov kuab tshuaj thiab ultraviolet hluav taws xob. Tsis tas li ntawd, nyob ntawm cov ntawv sau ntawm cov khoom, nws yog Halogen-free thiab nplaim retardant, uas yog cov txheej txheem tseem ceeb uas tau txais ntawv pov thawj thiab siv nyob rau Tebchaws Meskas. PUR CABLENY siv tau siv nyob rau hauv lub tshuab thiab kev tsim kho Hoobkas, muaj tshuab ua hlau, thiab kev lag luam automotive.
PVC - Qhov tseem ceeb tshaj plaws
Polyvinyl chloride (PVC) yog cov yas uas tau siv los ua cov khoom sib txawv txij li xyoo 1920. Nws yog cov khoom lag luam ntawm cov saw hlau polymerization ntawm vinyl chloride. Nyob rau hauv kev sib piv rau Elastomer Pur, pvc yog ib thermoplicity polymer. Yog tias cov khoom siv tau deformed hauv qab cua sov, nws tsis tuaj yeem rov qab los rau nws thawj lub xeev.
Raws li cov khoom siv sheathing, polyvinyl chloride muaj ntau yam ntawm cov peev xwm vim tias nws muaj peev xwm yoog tau qhov kev xav tau sib txawv los ntawm kev hloov nws cov kev sib piv. Nws cov neeg kho tshuab thauj khoom muaj peev xwm tsis zoo li lub siab, tab sis PVC kuj tseem ua tau ntau dua kev lag luam; Tus nqi nruab nrab ntawm polyurethane yog plaub zaug siab dua. Tsis tas li ntawd, PVC yog odorless thiab resistant rau dej, kua qaub thiab tu cov neeg ua haujlwm. Nws yog vim li no nws feem ntau siv nyob rau hauv kev lag luam khoom noj khoom haus lossis hauv cov chaw noo noo. Txawm li cas los xij, pvc tsis yog halogen-dawb, uas yog vim li cas nws tau suav hais tias tsis zoo rau cov ntawv thov tshwj xeeb. Tsis tas li ntawd, nws tsis yog inherently roj resistant, tab sis cov cuab yeej no tuaj yeem ua tiav los ntawm cov tshuaj sib ntxiv tshwj xeeb.
Tag
Ob leeg polyurethane thiab polyvinyl chloride muaj lawv cov txiaj ntsig thiab qhov tsis zoo raws li cov khoom siv cable thiab hlau nplaum hlau. Tsis muaj cov lus teb rau cov khoom twg yog qhov zoo tshaj rau txhua daim ntawv thov; Feem ntau yog nyob ntawm tus neeg xav tau ntawm daim ntawv thov. Muaj qee kis, ib qho sib txawv sib txawv sheathing cov khoom yuav yog qhov kev daws teeb meem zoo tshaj plaws. Yog li ntawd, peb txhawb cov neeg siv nrhiav cov lus qhia los ntawm cov kws tshaj lij uas paub txog cov khoom zoo thiab tsis zoo ntawm cov khoom sib txawv thiab cov tuaj yeem hnyav txhua lwm yam.
