1. Kev Txhim Kho Khoom Siv: Los ntawm PVC mus rau LSZH Cable Materials
Hauv cov chaw pej xeem loj xws li cov khw loj, cov chaw hauv nroog, cov tshav dav hlau, thiab cov tsev kho mob, cov xov hlau tsis yog tsuas yog lub luag haujlwm rau kev xa hluav taws xob xwb tab sis kuj tseem ua lub hauv paus tseem ceeb rau kev nyab xeeb thaum muaj hluav taws.
Piv nrog cov ntaub ntawv PVC cable ib txwm muaj, cov ntaub ntawv Low Smoke Zero Halogen (LSZH) sawv cev rau kev txhim kho tseem ceeb hauv kev ua haujlwm ntawm cov khoom siv. Cov ntaub ntawv LSZH tsis muaj halogen (lossis ua raws li cov kev txwv ntawm halogen uas tau teev tseg hauv cov qauv xws li IEC 60754). Thaum lub sijhawm hlawv, lawv tsis tso cov pa roj corrosive thiab txo cov pa luam yeeb. Los ntawm qhov pom ntawm cov khoom siv, qhov no daws tau zoo rau kev pheej hmoo kev nyab xeeb cuam tshuam nrog cov ntaub ntawv cable uas muaj halogen hauv cov xwm txheej hluav taws.
Qhov kev hloov pauv no los ntawm cov ntaub ntawv muaj halogen ib txwm muaj mus rau cov ntaub ntawv cable LSZH tau ua rau cov cable LSZH ua qhov kev taw qhia tseem ceeb rau cov cables hluav taws xob niaj hnub thiab cov kab ke cable tiv taus hluav taws.
2. Cov Kev Zoo ntawm Kev Ua Haujlwm Tseem Ceeb: Kev Tiv Thaiv Hluav Taws, Pa Luam Yeeb Tsawg, thiab Lub Tshuab Tsis Muaj Halogen
Los ntawm qhov pom ntawm cov ntaub ntawv cable, qhov zoo tseem ceeb ntawm LSZH cov cables nplaim taws muaj peb yam: nplaim taws retardancy, pa luam yeeb tsawg, thiab kev ua haujlwm tsis muaj halogen.
Cov ntaub ntawv cable LSZH siv cov txheej txheem tsis muaj halogen-free flame-retardant, xws li hlau hydroxides lossis phosphorus-nitrogen-based flame retardants. Thaum raug cua sov, cov txheej txheem no nqus tau ntau qhov cua sov, ua rau cov pa roj uas yooj yim hlawv, thiab txhawb kev tsim cov txheej char ntom ntom, ua rau cov nplaim taws tsis sib kis thiab txo cov dej ntws.
Tib lub sijhawm, cov ntaub ntawv LSZH tsim cov pa luam yeeb tsawg dua li cov ntaub ntawv PVC ib txwm muaj, pab tswj kom pom kev zoo dua hauv cov xwm txheej hluav taws thiab txhim kho kev khiav tawm. Tsis tas li ntawd, vim tias lawv tsis muaj halogen, cov khoom siv hlawv feem ntau yog cov dej ua pa thiab carbon dioxide, tsis tso cov pa lom lossis corrosive, yog li txo qhov kev puas tsuaj thib ob rau tib neeg thiab cov khoom siv.
Cov khoom sib xyaw ua ke no tsim lub hauv paus kev nyab xeeb ntawm LSZH cov xov hluav taws kub hauv cov ntawv thov kev tsim kho vaj tse rau pej xeem.
3. Cov Khoom Siv Hluav Taws Xob Tseem Ceeb: Tsim kom muaj ntau txheej tiv thaiv hluav taws
Los ntawm kev tsim qauv cable, kev ua tau zoo ntawm LSZH cov hluav taws kub-retardant cables nyob ntawm kev siv sib koom ua ke ntawm ntau cov ntaub ntawv cable.
LSZH tshuajua haujlwm ua cov khoom siv sab nraud thiab txiav txim siab qhov ua tau zoo ntawm cov cable uas tsis muaj pa luam yeeb ntau, tsis muaj halogen, thiab tsis ua rau hluav taws kub. Daim kab xev LSZH siv los txhim kho kev ruaj khov ntawm cov qauv thiab txhim kho qib hluav taws kub ntawm cov cable.
Daim kab xev mica Phlogopiteyog ib yam khoom siv hluav taws kub tseem ceeb. Nyob rau hauv cov xwm txheej hluav taws (feem ntau nyob ib puag ncig 750–950 ° C, nyob ntawm cov qauv xeem xws li IEC 60331 lossis BS 6387), nws tuaj yeem tswj tau hluav taws xob rwb thaiv tsev rau ib lub sijhawm, tsim lub hauv paus rau kev ua haujlwm hluav taws kub.
Cov ntaub nplaum uas thaiv dej thiab cov xov uas thaiv dej tau siv los txhim kho kev ntseeg tau mus ntev hauv qhov chaw noo thiab hnyav. Txawm hais tias tsis tas yuav tsum tau siv rau hauv tsev qhuav tas li, lawv feem ntau siv rau hauv cov kab ke hauv av, faus ncaj qha, thiab sab nraum zoov.
Los ntawm kev siv cov ntaub ntawv no ua ke, ib qho kev tiv thaiv ntau txheej uas muaj kev tiv thaiv hluav taws, kev tiv thaiv hluav taws, pa luam yeeb tsawg, thiab kev ua haujlwm tsis muaj halogen tuaj yeem ua tiav, ua tau raws li cov qauv thoob ntiaj teb.
4. Cov Ntawv Thov Engineering thiab Cov Kev Cai Ua Haujlwm ntawm Cov Khoom Siv
Hauv cov ntawv thov xws li cov tsev loj rau pej xeem, cov tsheb ciav hlau, thiab cov chaw hauv av, cov ntaub ntawv cable yuav tsum tsis yog tsuas yog muab kev nyab xeeb hluav taws xwb tab sis kuj tseem yuav tsum ua kom muaj kev ntseeg siab rau kev ua haujlwm mus sij hawm ntev.
Cov ntaub ntawv LSZH cable ua tau zoo feem ntau muaj cov khoom siv kho tshuab zoo heev (xws li kev tiv taus kev sib txhuam thiab kev cuam tshuam), kev tiv taus kev laus muaj zog, thiab kev ua haujlwm rwb thaiv hluav taws xob ruaj khov. Tib lub sijhawm, lawv muab kev ua haujlwm zoo, txhawb nqa kev nrawm nrawm thiab kev tsim khoom loj. Cov khoom no tau txiav txim siab ncaj qha los ntawm kev tsim cov khoom siv thiab kev tswj cov txheej txheem tsim khoom, tsim lub hauv paus rau kev ua haujlwm cable txhim khu kev qha.
Hais txog kev ua raws li txoj cai, LSZH cables feem ntau yuav tsum tau ua raws li cov qauv thoob ntiaj teb hauv qab no:
Hluav taws kub tsis kam: IEC 60332 series
Qhov ceev ntawm cov pa luam yeeb: IEC 61034
Cov ntsiab lus halogen: IEC 60754
Kev tiv thaiv hluav taws: IEC 60331 lossis BS 6387
Raws li cov ntaub ntawv cable txuas ntxiv mus rau kev nyab xeeb thiab kev ua tau zoo dua, kev siv cov ntaub ntawv cable LSZH, daim kab xev phlogopite mica, thiab cov ntaub ntawv thaiv dej yuav nthuav dav ntxiv, tsim cov cib fim tshiab rau cov neeg muab khoom siv cable hauv kev lag luam thoob ntiaj teb.
