Halogen-Free Flame Retardant Cable Material Modifier

Halogen-Free Flame Retardant Cable Material Modifier

Nrog rau kev txhim kho thev naus laus zis, muaj kev xav tau ntau ntxiv rau kev nyab xeeb thiab kev ntseeg siab hauv thaj chaw kaw thiab cov neeg nyob ruaj khov xws li chaw nres tsheb hauv subway, cov tsev siab siab, nrog rau cov chaw tseem ceeb rau pej xeem xws li nkoj thiab nuclear fais fab nroj tsuag. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau tsim cov cables tshiab uas muaj pa taws tsawg, tsis muaj halogen, thiab nplaim hluav taws. Thaum ntxov xyoo 1980, cov teb chaws tsim kho thoob ntiaj teb tau pib tshawb fawb thiab tsim cov pa luam yeeb tsawg halogen-dawb nplaim-retardant cov ntaub ntawv thiab cables. Halogen-dawb nplaim hluav taws-retardant cables tau pom txij li tau txais sai sai thiab siv dav. Hauv Suav teb, cov tuam txhab xaim thiab cable hauv nroog xws li Shanghai, Shenyang, Suzhou, Sichuan, Xiangtan, thiab Wuxi tau ua tiav tsim cov hluav taws xob hluav taws xob hluav taws xob, nplaim hluav taws xob mining roj hmab-sheathed saj zawg zog cables, nplaim hluav taws-retardant shipboard cables, thiab lwm yam khoom muaj feem xyuam.

Cov kev hloov kho yog siv nyob rau hauv halogen-dawb nplaim-retardant muab tub lim-filled composite cable cov ntaub ntawv, xws li txhuas hydroxide thiab magnesium hydroxide, los txhim kho lub compatibility thiab adhesion ntawm polyolefin matrix thiab inorganic nplaim retardants. Lawv txhim khu kev sib tawg thiab kev sib raug zoo ntawm aluminium hydroxide thiab magnesium hydroxide, yog li ua kom cov nplaim hluav taws kub nyhiab ntawm cov khoom siv cable, txo cov pa luam yeeb, cov pa luam yeeb, tso cua sov, thiab cov pa roj carbon monoxide ntau lawm, ua rau cov pa oxygen index, thiab txhim kho cov dej tsis kam. Cov kev hloov pauv no ua rau muaj txiaj ntsig zoo rau cov khoom siv kho tshuab thiab thermal ntawm cov khoom. Ntxiv ib qho me me tuaj yeem txhim kho cov khoom sib xyaw ua ke ntawm cov khoom siv kho tshuab, ua kom lub zog tensile thiab elongation, nrog rau kev ua haujlwm thermal thiab nplaim hluav taws.

Kev siv ntau:

1. Coupling Agent: Siv rau cov nplaim hluav taws tsis muaj halogen xws li txhuas hydroxide thiab magnesium hydroxide los txhim kho kev sib raug zoo thiab adhesion ntawm polyolefin matrix thiab inorganic nplaim retardants. Ntxiv 8% -10% tuaj yeem txhim kho cov khoom siv kho tshuab thiab thermal kuj ntawm cov khoom sib xyaw. Piv nrog rau cov khoom sib txuas xws li silane, titanate, aluminate, thiab phosphate esters, nws muab kev txhim kho zoo dua hauv cov khoom siv ntawm cov khoom siv polyolefin cable.
2. Dispersing Promoter: Siv nyob rau hauv polyolefin masterbatches, nplaim-retardant masterbatches, thiab degradable masterbatches. Vim nws muaj zog sib cuam tshuam nrog pigments, dyes, thiab nplaim retardants, nws txhawb cov dispersion ntawm cov additives nyob rau hauv lub polyolefin carrier resin.
3. Bonding Promoter: Muaj polarity siab thiab reactivity. Ntxiv ib qho me me tuaj yeem txhim kho cov xim pleev xim, adhesion, thiab kev sib raug zoo ntawm cov khoom.
