Qhov sib txawv ntawm cov cable tiv taus hluav taws, cov cable tsis muaj halogen thiab cov cable tiv taus hluav taws:
Cov xov hluav taws kub hnyiab yog tus yam ntxwv los ntawm kev ncua qhov kev kis ntawm cov nplaim taws raws cov xov hluav taws kom hluav taws tsis nthuav dav. Txawm hais tias nws yog ib txoj xov hluav taws lossis ib pawg ntawm cov xwm txheej tso, cov xov hluav taws kub hnyiab tuaj yeem tswj qhov kev kis ntawm cov nplaim taws hauv qee qhov ntau thaum hlawv, yog li nws tuaj yeem zam kev puas tsuaj loj los ntawm kev kis hluav taws. Yog li txhim kho qib kev tiv thaiv hluav taws ntawm cov xov hluav taws. Cov ntaub ntawv tiv thaiv hluav taws kub hnyiab feem ntau suav nrog daim kab xev tiv thaiv hluav taws,hluav taws kub retardant filler hluathiab cov khoom siv PVC lossis PE uas muaj cov tshuaj ntxiv uas tiv taus hluav taws.
Cov yam ntxwv ntawm cov xov hluav taws xob halogen-free uas tsis muaj pa luam yeeb tsawg tsis yog tsuas yog tias nws muaj kev ua tau zoo ntawm cov nplaim taws xwb, tab sis kuj tseem tias cov khoom siv uas tsim cov xov hluav taws xob halogen-free uas tsis muaj pa luam yeeb tsawg tsis muaj halogen, qhov xeb thiab tshuaj lom ntawm kev sib xyaw yog qis, thiab cov pa luam yeeb tsim tawm me me, yog li txo qhov kev puas tsuaj rau tus neeg, cov cuab yeej thiab cov khoom siv, thiab ua rau kev cawm neeg raws sijhawm yooj yim dua thaum muaj hluav taws. Nws cov ntaub ntawv siv feem ntau yogcov khoom siv uas tsis muaj pa luam yeeb tsawg (LSZH)thiab daim kab xev tiv thaiv hluav taws uas tsis muaj halogen.
Cov xov hluav taws kub tuaj yeem ua haujlwm ib txwm rau ib lub sijhawm hauv qhov xwm txheej ntawm nplaim taws kom ntseeg tau tias txoj kab muaj kev ncaj ncees. Cov pa roj acid thiab pa luam yeeb tsim tawm thaum lub sijhawm hluav taws kub cable combustion tsawg dua, thiab kev ua haujlwm hluav taws kub tau zoo dua. Tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej ntawm combustion nrog dej tsuag thiab kev cuam tshuam tshuab, lub cable tseem tuaj yeem ua haujlwm tag nrho ntawm txoj kab. Cov xov hluav taws kub feem ntau siv cov khoom siv hluav taws kub siab xws li phlogopa daim kab xev thiabdaim kab xev mica hluavtaws.
1. Dab tsi yog hluav taws kub retardant cable?
Cov xov hluav taws kub txhais tau hais tias: nyob rau hauv cov xwm txheej xeem tshwj xeeb, cov qauv raug hlawv, tom qab tshem tawm qhov chaw tua hluav taws xeem, qhov kis ntawm cov nplaim taws tsuas yog nyob rau hauv qhov txwv, thiab cov nplaim taws seem lossis cov hlawv seem tuaj yeem tua nws tus kheej hauv lub sijhawm txwv.
Nws cov yam ntxwv tseem ceeb yog: thaum muaj hluav taws, nws yuav raug hlawv thiab tsis tuaj yeem khiav, tab sis nws tuaj yeem tiv thaiv kev kis hluav taws. Hauv cov lus nrov, thaum lub cable kub hnyiab, nws tuaj yeem txwv kev kub hnyiab rau hauv thaj chaw hauv zos, tsis txhob kis, tiv thaiv lwm yam khoom siv, thiab zam kev ua rau muaj kev poob ntau dua.
2. Cov yam ntxwv ntawm cov qauv ntawm cov hluav taws xob retardant cable.
Cov qauv ntawm cov xov hluav taws xob zoo ib yam li cov xov hluav taws xob ib txwm muaj, qhov sib txawv yog tias nws cov txheej rwb thaiv tsev, lub plhaub, lub plhaub sab nraud thiab cov ntaub ntawv pabcuam (xws li daim kab xev thiab cov ntaub ntawv sau) yog ua tiav lossis ib feem ntawm cov ntaub ntawv hluav taws xob.
Cov ntaub ntawv siv feem ntau suav nrog PVC uas tiv taus hluav taws (rau cov xwm txheej dav dav uas tiv taus hluav taws), daim kab xev halogenated lossis halogen-free flame retardant (rau cov chaw uas muaj kev xav tau ib puag ncig siab), thiab cov khoom siv roj hmab ceramic silicone ua haujlwm siab (rau cov xwm txheej siab uas xav tau ob qho tib si tiv taus hluav taws thiab tiv taus hluav taws). Tsis tas li ntawd, pab puag ncig cov qauv cable thiab tiv thaiv hluav taws kis mus rau qhov sib txawv, yog li txhim kho kev ua haujlwm tiv taus hluav taws tag nrho.
3. Cov xov hluav taws kub yog dab tsi?
Cov xov hluav taws kub txhais tau hais tias: nyob rau hauv cov xwm txheej xeem tshwj xeeb, cov qauv raug hlawv hauv nplaim taws, thiab nws tseem tuaj yeem ua haujlwm ib txwm rau ib lub sijhawm.
Nws lub ntsiab lus tseem ceeb yog tias lub cable tseem tuaj yeem ua haujlwm li qub rau ib lub sijhawm hauv qab qhov kub hnyiab. Feem ntau, thaum muaj hluav taws, lub cable yuav tsis kub hnyiab ib zaug, thiab lub voj voog muaj kev nyab xeeb dua.
4. Cov yam ntxwv ntawm cov qauv ntawm cov xov hluav taws xob refractory.
Cov qauv ntawm cov xov hluav taws kub-resistant yog qhov zoo ib yam li cov xov hluav taws xob ib txwm muaj, qhov sib txawv yog tias tus neeg xyuas pib siv tus neeg xyuas pib tooj liab nrog kev tiv thaiv hluav taws zoo (qhov kub ntawm tooj liab yog 1083 ℃), thiab cov txheej hluav taws-resistant ntxiv rau ntawm tus neeg xyuas pib thiab txheej rwb thaiv tsev.
Cov txheej txheem refractory feem ntau yog qhwv nrog ntau txheej ntawm phlogopite lossis cov ntaub nplaum mica hluavtaws. Qhov kub siab tiv taus ntawm cov siv mica sib txawv ntau heev, yog li kev xaiv cov siv mica yog qhov tseem ceeb uas cuam tshuam rau qhov hluav taws tsis kam.
Qhov sib txawv tseem ceeb ntawm cov cable uas tiv taus hluav taws thiab cov cable uas tiv taus hluav taws:
Cov xov hluav taws kub tuaj yeem tswj tau lub zog hluav taws xob ib txwm rau ib lub sijhawm thaum muaj hluav taws kub, thaum cov xov hluav taws kub tsis muaj qhov no.
Vim tias cov xov hluav taws kub tuaj yeem tswj tau qhov kev ua haujlwm ntawm cov voj voog tseem ceeb thaum muaj hluav taws kub, lawv ua lub luag haujlwm tseem ceeb hauv cov tsev niaj hnub thiab cov tsev lag luam. Lawv feem ntau siv rau hauv cov voj voog fais fab txuas cov chaw fais fab thaum muaj xwm txheej ceev rau cov khoom siv tiv thaiv hluav taws, cov tshuab ceeb toom hluav taws, cov khoom siv cua thiab cov pa luam yeeb, cov teeb qhia kev, cov qhov hluav taws xob thaum muaj xwm txheej ceev, thiab cov tshuab nqa thaum muaj xwm txheej ceev.
