Twg Tus Cable Jacket Yog Qhov Zoo Tshaj Rau Koj Daim Ntawv Thov?
Thaum muas khoom cab lossis cable sib txuas, koj muaj peev xwm txhawj txog tej yam xws li tus neeg xyuas AWG loj, tiv thaiv rau EMI / RFI, connector molding siv, thiab lwm yam. Vim li cas koj yuav xav tau ib qho kev xav rau lub tsho uas nyuam qhuav mus ncig ntawm cov neeg yaus? Ua tau, cable tsho tseem ceeb dua li qhov koj xav. Xaiv lub hnab tsho tsis muaj teeb meem yuav muaj qhov cuam tshuam rau ntau yam khoom, los ntawm kev txuas lub neej ntawm koj lub xov tooj, los siv cov hlua hauv lub tshav pob. Cov nram qab no yuav ua luv luv qhia ntau cov kab siv looj siv rau koj cov neeg ua tim khawv.
Lub tsho cable yog thawj kab ntawm txhua yam khoom siv, ya raws, nplaim taws thiab tshuaj tiv thaiv rau ib kab. Ntxiv dua yog, lub tsho muaj kev tiv thaiv rau kev tiv thaiv thiab cov neeg sib tw. Nws tivthaiv lub xov tooj cua ntawm kev puas tsuaj rau lub sijhawm thiab tom qab kev txhim kho. Cov ris tsho tsis npaj los hloov cov hlua kev nruam, tab sis lawv muaj peev xwm muab tau theem siab ntawm kev ya raws thiab tshuaj tiv thaiv nrog UV thiab kev tiv thaiv kab mob qub. Cov duab hauv qab no qhia tau hais tias tus qauv ntawm qhov kho qhov muag tau pom.

PVC (polyvinyl chloride) yog cov khoom siv hlau nplaum uas siv ntau tshaj plaws hauv cov xov hlau thiab txoj hlua cable. Pib xyoo 1935, thaum nws xub pib muaj, kev siv cov PVC tuaj yeem sai vim nws pheej yig, yooj yim ua thiab zoo ua ke ntawm tag nrho cov khoom xws li hluav taws thiab cov tshuaj ua haujlwm. Txawm li ntawd los no lub hnab tsho kuj muaj qhov tsis txaus. Piv txwv, PVC yog ib qho khoom siv thermoplastic, yog li nws tsis tuaj yeem noj siab. Nyob rau hauv cov lag luam uas siv ntau cov khoom kub, los yog qhov chaw muaj ntau qhov kev kub siab, kev siv PVC yuav tsum raug zam, vim nws nyiam mus ua los yog deform thaum lub siab kom sov.
Kev txhawj xeeb ntxiv rau cov neeg ua haujlwm kev nyab xeeb thiab kev siv hluav taws xob hauv lub voj voog yog tsav tsheb rau kev haus luam yeeb qis, xoom-halogen (LSZH). LSZH yog tsim los ntawm cov thermoplastic lossis thermoset compounds uas yuav kis tau cov pa luam yeeb tsawg tsawg thiab tsis muaj halogen thaum lub xov tooj los yog lub thaj ua haujlwm raug puas tsuaj los ntawm hluav taws los yog lub teeb meem luv luv. Hom khaub hnab khaub ncaws no feem ntau siv hauv cov chaw tsis muaj pa xws li aircraft, cov tsheb nqaj hlau, lossis nkoj. Nws yog qhov nrov nrov thiab, qee qhov yog, qhov uas yuav tsum tau muaj rau kev tiv thaiv cov neeg thiab khoom siv los ntawm cov pa roj carbon dioxide thiab corrosive.
Polyurethane, tseem hu ua PUR, yog khoom siv thermoplastic, feem ntau siv hauv qhov chaw hnyav. PUR tiv thaiv kom o thiab degradation thaum raug dej rau lub sijhawm ntev, ua kom tsim nyog rau cov cuab yeej cuab tam hauv lub nkoj, xws li cov kab mob submarine. Dhau li ntawd, nws txoj kev yooj yim thiab kev khov kho nws cia nws yog ib qho chaw pabcuam rau kev sib txuas ntawm cov khoom ntawm kev co thiab kev poob siab. Txawm li cas los xij, lub tsho PUR nkaus xwb yog tias nws tseem kim tshaj lwm hom khaub hnab.
EPR (ethylene propylene roj hmab) yog kev sib txuas sib txuas, thermosetting roj hmab hluav taws kub. Nws muaj cov khoom siv hluav taws xob zoo nrog rau koj lub thermal stability thiab yooj. Nws tuaj yeem tiv taus qhov kub thiab txias txias mus txog -60 Celsius degree. Nrog cov zoo zoo kub kub kub txhua yam, thaum formulated kom raug, EPR yuav theej nplaim retardant zoo li.
Raws li ib daim ntawv ntawm hluavtaws roj hmab, silicon muaj cov khoom hluav taws xob zoo heev nrog rau kev ua kom muaj zog, tsis muaj noo noo, huab cua thiab hluav taws xob ua haujlwm. Thaum cov roj hmab kub hnyiab kub hnyav, nws tsim cov ntoo uas tsis yog cov uas ua haujlwm, uas qee zaum, tuaj yeem ua kom muaj lub meej mom ntawm txoj hluav taws xob hluav taws xob. Silicon lub tsho yog feem ntau siv rau cov ntawv sau ntau qhov xov tooj hlau dabtsi yog qhov yuav tsum tau ua.
Cable tsho tsis yog yooj yim npaum li koj xav. Thaum twg koj xaiv lub thaj ua haujlwm lossis cov neeg nqa khoom, koj yuav tsum tau coj lub tsho loj rau hauv kev saib xyuas. Muaj ntau hom kab khaub ncaws uas muaj nyob rau hauv kev ua lag luam thiab txhua tus tuaj yeem siv tau rau hauv ntau yam. Tom qab nyeem zaj no, vam tias koj tuaj yeem xaiv qhov zoo tshaj plaws rau koj daim ntawv thov.
