Dab tsi yog Qhov Kev Ntsuas Tshwj Xeeb Ntawm Cable Flame Retardant Qib?

---

Nyob rau tam sim no, tus cable kev lag luam yog accustomed rau nplaim retardant (Hluav taws kub Retardant), LowSmokeHalogenFree (LSOH) los yog tsawg halogen tsawg pa luam yeeb (LSF), hluav taws-resistant (FireResistant), lwm yam., nrog qee qhov hluav taws kub ua haujlwm ntawm lub cable, tau sau ua ke hu ua hluav taws-resistant cable.

1. Nplaim-retardant cable (Nplaim Retardant)

Nplaim retardant cable yog tus cwj pwm los ntawm kev ncua kev sib kis ntawm cov nplaim taws raws li cov cable kom cov hluav taws tsis nthuav dav.

Vim nws tus nqi qis dua, nws yog ib tug loj tus naj npawb ntawm cov hluav taws-resistant cables siv nyob rau hauv lub cable hom.

Seb nws yog ib qho cable los yog ib pob ntawm cov xwm txheej nteg, cov kab hluav taws xob raug hlawv thaum qhov hluav taws kub sib kis tuaj yeem tswj tau nyob rau hauv ib qho chaw.

Yog li ntawd, koj tuaj yeem zam qhov kev puas tsuaj loj tshwm sim los ntawm hluav taws xob hluav taws xob qeeb combustion, yog li kev txhim kho qib ntawm kev tiv thaiv hluav taws ntawm cov kab hluav taws xob.

2. Halogen-dawb pa taws retardant cable (LSOH)

Halogen-free low-smoke cable yog tus cwj pwm tsis yog los ntawm cov khoom siv hluav taws xob zoo heev tab sis kuj yog cov khoom siv hluav taws xob tsis muaj pa taws tsawg uas tsis muaj halogens., muaj corrosive tsawg, thiab muaj tshuaj lom thaum hlawv, tsim cov pa luam yeeb tsawg heev.

Qhov no txo ​​qhov kev puas tsuaj rau tib neeg lub cev, cuab yeej, thiab khoom siv, thiab pab txhawb kev cawm raws sijhawm thaum muaj hluav taws kub.

Txawm hais tias halogen-dawb tsis muaj pa taws tsawg-tsawg nplaim hluav taws xob muaj cov nplaim hluav taws zoo heev, Corrosion Kuj, thiab cov pa luam yeeb tsawg, nws cov khoom siv tshuab thiab hluav taws xob yog me ntsis phem dua li cov cables zoo tib yam.

3. Tsawg-halogen hluav taws xob hluav taws xob qis hluav taws xob cable (LSF)

Tsawg halogen tsis tshua muaj pa taws hluav taws xob hluav taws xob cable hydrogen chloride tso tawm thiab cov pa taws ua kom pom tseeb ntawm cov nplaim hluav taws xob thiab cov hluav taws xob tsis muaj halogen tsis tshua muaj pa taws retardant cable.

Tsawg halogen (LowHalogen) txoj hluas Cov ntaub ntawv tseem yuav muaj halogens, tab sis cov ntsiab lus qis dua.

Cov kab no yog tus cwj pwm tsis yog tsuas yog muaj cov khoom siv hluav taws xob xwb tab sis kuj tso pa tawm tsawg dua thiab qis dua hydrogen chloride emissions thaum combustion..

Cov no tsawg-halogen, Cov kab hluav taws xob uas tsis tshua muaj hluav taws xob hluav taws xob feem ntau yog ua los ntawm polyvinyl chloride (PVC) raws li cov khoom siv hauv paus thiab ua tiav nrog cov nplaim retardants zoo heev, HCL absorbers, thiab haus luam yeeb suppressants.

Yog li ntawd, Cov khoom siv hluav taws kub retardant no txhim kho qhov ua tau zoo ntawm cov nplaim hluav taws xob zoo tib yam PVC khoom.

4. Hluav taws kub-resistant cable (FireResistant)

Hluav taws kub-resistant cable muaj peev xwm tswj tau ib txwm ua hauj lwm rau ib lub sij hawm ntawm lub sij hawm nyob rau hauv cov ntaub ntawv ntawm cov nplaim taws kub hnyiab tau thiab muaj peev xwm tswj tau cov kev ncaj ncees ntawm txoj kab. (CircuitIntergrity).

Hluav taws kub-resistant nplaim retardant cables tsim cov pa roj acid tsawg dua thaum hlawv, thiab hluav taws kub-resistant nplaim retardant kev ua tau zoo heev, tshwj xeeb tshaj yog thaum hlawv, nrog rau cov tshuaj tsuag dej thiab mechanical shock, lub cable tseem tuaj yeem tswj tau qhov kev ncaj ncees ntawm txoj kab khiav haujlwm.

5. Nplaim-retardant cable qauv thiab qib

Cov kev qhia tseem ceeb ntawm cov cable koom nrog kev nyab xeeb hluav taws yog cov nplaim hluav taws kub ntawm CO2 cable, qhov ntom ntawm cov pa luam yeeb, thiab gas toxicity.

U.S. Cov qauv hluav taws kub muaj kev txhawj xeeb ntau dua rau thawj ob qhov teeb meem, tab sis Tebchaws Europe thiab Tebchaws Meskas muaj qhov sib txawv kiag li ntawm kev nyab xeeb hluav taws.

Lub tswv yim qub neeg Asmeskas yog tias lub hauv paus ua rau hluav taws yog tsim cov pa roj carbon monoxide (CO) Cov pa phem thiab cov cua kub tom qab tso tawm los ntawm CO rau CO2 thaum lub sij hawm combustion txheej txheem. Yog li ntawd, tswj cov cua sov tso tawm thaum lub sij hawm combustion tuaj yeem txo qhov hluav taws kub.

Teb chaws Europe tau ib txwm ntseeg hais tias tus nqi ntawm halogenated acid (HCL) tso tawm thaum combustion, corrosiveness ntawm cov pa, qhov concentration ntawm cov pa luam yeeb, thiab qhov toxicity ntawm cov pa roj yog qhov tseem ceeb ntawm kev txiav txim siab seb tib neeg puas tuaj yeem muaj kev nyab xeeb tawm ntawm qhov chaw ntawm hluav taws.
