Xaiv cov ntaub ntawv zoo yog qhov tseem ceeb rau kev ua kom ruaj khov mus ntev thiab kev ua haujlwm ntawm cov khoom siv kho qhov muag. Cov ntaub ntawv sib txawv coj txawv nyob rau hauv ib puag ncig huab cua - cov ntaub ntawv zoo tib yam tuaj yeem ua nkig thiab tawg ntawm qhov kub thiab txias, thaum nyob rau hauv qhov kub siab lawv yuav soften los yog deform.
Hauv qab no yog ob peb yam khoom siv feem ntau siv hauv kev tsim kho qhov muag cable, txhua tus muaj nws tus kheej zoo thiab cov ntawv thov tsim nyog.
1. PBT (Polybutylene Terephthalate)
PBT yog cov khoom siv dav tshaj plaws rau kev kho qhov muag cable xoob hlab.
Los ntawm kev hloov kho - xws li ntxiv cov saw hloov tau yooj yim - nws qhov kub thiab txias brittleness tuaj yeem txhim kho tau zoo, yooj yim ua tau raws li qhov xav tau ntawm -40 ° C.
Nws tseem tswj tau zoo heev rigidity thiab seem stability nyob rau hauv siab kub.
Qhov zoo: sib npaug kev ua tau zoo, tus nqi-zoo, thiab dav siv tau.
2. PP (Polypropylene)
PP muab qhov zoo ntawm qhov kub thiab txias, tiv thaiv kev tawg txawm nyob rau hauv qhov chaw txias heev.
Nws kuj tseem muaj qhov ua tau zoo hydrolysis zoo dua li PBT. Txawm li cas los xij, nws cov modulus qis dua me ntsis, thiab rigidity tsis muaj zog.
Kev xaiv ntawm PBT thiab PP yog nyob ntawm tus qauv tsim thiab kev xav tau ntawm kev ua haujlwm.
3. LSZH (Low Smoke Zero Halogen Compound)
LSZH yog ib qho ntawm cov ntaub ntawv nrov tshaj plaws siv niaj hnub no.
Nrog cov txheej txheem polymer siab heev thiab cov khoom siv sib xyaw ua ke, cov khoom siv zoo LSZH tuaj yeem ua tau raws li -40 ° C qhov ntsuas kub qis thiab ua kom ruaj khov mus ntev ntawm 85 ° C.
Lawv muaj cov nplaim hluav taws zoo heev (tsim cov pa luam yeeb tsawg thiab tsis muaj halogen gases thaum combustion), nrog rau muaj zog tiv thaiv kev ntxhov siab tawg thiab tshuaj lom neeg corrosion.
Nws yog ib qho kev xaiv zoo tshaj plaws rau cov nplaim hluav taws xob thiab cov kab mob ib puag ncig.
4. TPU (Thermoplastic Polyurethane)
Paub tias yog "tus huab tais ntawm txias thiab hnav tsis kam," TPU sheathing cov ntaub ntawv tseem hloov tau txawm tias nyob rau hauv qhov kub thiab txias heev thaum muab superior puas, roj, thiab kua muag kuj.
Nws yog qhov zoo tagnrho rau cov hlua khi hlua, cov hlua khi hlua khi, thiab cov tsheb thauj mus los uas yuav tsum tau txav mus los tsis tu ncua lossis yuav tsum tiv taus qhov hnyav hnyav.
Txawm li cas los xij, kev saib xyuas yuav tsum tau them rau qhov kub thiab txias thiab hydrolysis tsis kam, thiab cov qib siab tau pom zoo.
5. PVC (Polyvinyl Chloride)
PVC yog ib qho kev xaiv pheej yig rau optical cable sheaths.
Tus qauv PVC zoo li tawv thiab ua nkig hauv qab -10 ° C, ua rau nws tsis haum rau qhov kub thiab txias heev.
Txias-resistant los yog kub-kub PVC formulations txhim kho kev yooj yim los ntawm kev ntxiv ntau ntawm plasticizers, tab sis qhov no yuav txo tau txhua yam muaj zog thiab aging kuj.
PVC tuaj yeem txiav txim siab thaum tus nqi ua haujlwm yog qhov tseem ceeb thiab kev cia siab rau lub sijhawm ntev tsis siab.
Cov ntsiab lus
Txhua yam ntawm cov khoom siv kho qhov muag no muaj qhov zoo sib xws nyob ntawm daim ntawv thov.
Thaum tsim los yog tsim cov cables, nws yog ib qho tseem ceeb uas yuav tau xav txog tej yam kev mob ntawm ib puag ncig, kev ua haujlwm ntawm kev ua haujlwm, thiab kev pabcuam lub neej kom xaiv cov khoom tsim nyog tshaj plaws.
