Cov Lus Qhia Xaiv Rau Sab Hauv Thiab Cov Khoom Siv Sab Hauv Hauv Cov Cables Uas Tsis Muaj Halogen Thiab Tsis Muaj Pa Luam Yeeb

Hauv kev tsim cov cables uas tsis muaj halogen thiab tsis muaj pa luam yeeb, kev xaiv cov khoom siv cable LSZH rau sab hauv thiab lub plhaub sab hauv cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov cable, kev nyab xeeb ib puag ncig, thiab lub neej ua haujlwm. Lub plhaub sab hauv nyob nruab nrab ntawm cov rwb thaiv tsev thiab lub tsho tiv thaiv, muab kev nplij siab thiab kev sib cais; lub plhaub sab hauv nyob sab nraud ntawm lub tsho tiv thaiv, muab kev tiv thaiv tag nrho. Ob qho tib si yuav tsum ua tau raws li qhov yuav tsum tau ua kom tsis muaj halogen, tsis muaj pa luam yeeb, tsis muaj hluav taws, thiab zoo rau ib puag ncig.

I. Kev Xaiv Khoom Siv Rau Sab Hauv Hauv Cov Cables Uas Tsis Muaj Halogen Uas Muaj Pa Luam Yeeb Tsawg

Lub txheej sab hauv yuav tsum tsis yog-hygroscopic, muaj cov yam ntxwv halogen-free uas tsis muaj pa luam yeeb tsawg, thiab sib xws nrog lub kaw lus rwb thaiv tsev. Cov ntaub ntawv sab hauv LSZH feem ntau siv suav nrog halogen-free flame-retardant polyolefin thiab halogen-free flame-retardant polyethylene (HF-PE), uas muaj cov khoom siv kho tshuab zoo heev thiab kev ruaj khov flame-retardant. Cov txheej txheem extrusion lossis qhwv tuaj yeem siv los ua kom tau raws li cov qauv ntawm cov cable sib txawv.

II. Kev Xaiv Khoom Siv Rau Lub Tsho Sab Hauv Uas Tsis Muaj Halogen-Phem Tsawg

Cov yam ntxwv tseem ceeb ntawm lub plhaub sab hauv yog cov pa luam yeeb tsawg, tsis muaj halogen, thiab tsis kub hnyiab. Cov ntaub ntawv tseem ceeb suav nrog polyolefin uas tsis muaj pa luam yeeb tsawg thiab roj hmab EVM (ethylene-vinyl acetate roj hmab). Cov roj hmab polyolefin uas tsis muaj pa luam yeeb tsawg tsis tso tawm cov pa roj halogen acid lom thaum hlawv, muab kev ua haujlwm zoo thiab kev siv nyiaj tsawg. Roj hmab EVM muaj cov yam ntxwv zoo heev uas tiv taus kub siab, tiv taus roj, thiab tsis kub hnyiab tsawg, ua rau nws siv dav hauv cov ntawv thov siab xws li cov xov hlau hauv dej hiav txwv, cov xov hlau hauv av, thiab cov xov hlau tsheb ciav hlau.

III. Kev siv roj hmab EVM hauv cov hlua khi uas tsis muaj pa luam yeeb tsawg

Cov roj hmab EVM tam sim no yog cov khoom siv zoo tshaj plaws rau cov hlua khi hluav taws xob uas tsis muaj halogen thiab tsis muaj pa luam yeeb ntau. Nws tau dhau daim ntawv pov thawj hluav taws kub hauv kev siv hlua khi hauv dej hiav txwv thiab kev khawb av. Cov tshuaj EVM uas tiv taus hluav taws kub ua tiav cov pa oxygen ntawm 38 txog 42, tsim cov pa luam yeeb tsawg, thiab tsis muaj tshuaj lom thaum hlawv. Nrog rau qhov kub thiab txias ua haujlwm tas mus li ntawm 90 ° C txog 105 ° C, nrog rau kev tiv taus cov roj av thiab kev laus zoo heev, roj hmab EVM yog cov khoom siv zoo tshaj plaws rau cov hlua khi hluav taws kub tshwj xeeb.

IV. Kev Tshuaj Xyuas Tus Nqi thiab Cov Txiaj Ntsig ntawm Cov Khoom Siv Cable Uas Tsis Muaj Halogen Uas Muaj Pa Luam Yeeb Tsawg

Cov ntaub ntawv cable LSZH feem ntau kim dua li cov khoom siv ib txwm muajPVCcov cables, feem ntau yog vim muaj cov khoom siv hluav taws xob uas zoo rau ib puag ncig xws li magnesium hydroxide thiab aluminium hydroxide. Txawm li cas los xij, hauv kev siv kev nyab xeeb xws li kev thauj mus los rau pej xeem, cov chaw khaws ntaub ntawv, cov nkoj hauv hiav txwv, thiab cov tsev siab, tus nqi kev nyab xeeb ntawm cov khoom siv hluav taws xob uas tsis muaj pa luam yeeb halogen tsawg yog qhov tseem ceeb heev. Tam sim no, roj hmab EVM thiab cov polyolefins uas ua haujlwm tau zoo uas tsis muaj halogen tau ua tiav cov ntawv thov loj uas pheej yig thiab tau dhau los ua cov kev xaiv tseem ceeb hauv kev lag luam.

Kev xaiv cov ntaub sab hauv thiab cov ntaub ntawv sab hauv kom haum rau cov xov hluav taws xob uas tsis muaj pa luam yeeb tsawg halogen yuav tsum tau xav txog kev tiv thaiv hluav taws, cov kev cai ib puag ncig, cov xwm txheej ntawm daim ntawv thov, thiab kev siv nyiaj tsim nyog.IB LUB NTIJ TEBtshwj xeeb hauv kev muab cov khoom siv cable LSZH tag nrho, suav nrog roj hmab EVM, cov pa luam yeeb tsawg halogen-free flame-retardant polyolefin, thiab cov tshuaj cable tsis muaj halogen-free flame-retardant, muab cov kev daws teeb meem cable ib zaug thiab kev txhawb nqa kev siv tshuab.

Yog xav tau cov lus qhia txog kev xaiv cov khoom siv, kev kuaj qauv, lossis cov lus hais txog cov khoom, thov koj xav tiv tauj peb kom tau kev pab tshaj lij.
