Halogen-Free Flame Retardant Cable Material Modifier

Halogen-Free Flame Retardant Cable Material Modifier

Ndi kupita patsogolo kwaukadaulo, pakufunika kufunikira kwa chitetezo ndi kudalirika m'malo otsekeredwa komanso okhala ndi anthu ambiri monga masiteshoni apansi panthaka, nyumba zazitali, komanso malo ofunikira aboma monga zombo ndi mafakitale amagetsi a nyukiliya. Chifukwa chake, pakufunika mwachangu kupanga mitundu yatsopano ya zingwe zokhala ndi utsi wochepa, zopanda halogen, komanso zoletsa moto. Kumayambiriro kwa zaka za m’ma 1980, maiko otukuka padziko lonse lapansi anayamba kufufuza ndi kupanga zipangizo ndi zingwe zopanda utsi wosatentha kwambiri za halogen. Zingwe zopanda halogen zosagwira moto kuyambira pamenepo zayamba kutengedwa mwachangu komanso kugwiritsidwa ntchito mofala. Ku China, opanga mawaya ndi zingwe m’mizinda monga Shanghai, Shenyang, Suzhou, Sichuan, Xiangtan, ndi Wuxi apanga motsatizanatsatizana zingwe zamagetsi zosagwira moto, zingwe zomangira mphira zosagwira moto, zingwe zamasitima zosagwira moto, ndi zina.

Zosintha zimagwiritsidwa ntchito pazingwe zodzaza ndi ma halogen-filler-retardant-filler-filler-filler, monga aluminium hydroxide ndi magnesium hydroxide, kuti zithandizire kugwirizanitsa ndi kumamatira pakati pa polyolefin matrix ndi inorganic flame retardants. Amathandizira kubalalitsidwa ndi kuyanjana kwa aluminiyamu hydroxide ndi magnesium hydroxide, potero kumapangitsa kuti chiwongolero cha chingwecho chiwonjezeke, kuchepetsa index ya utsi, kutulutsa utsi, kutulutsa kutentha, komanso kupanga mpweya wa monoxide, kukulitsa index ya okosijeni, ndikuwongolera kukana kudontha. Zosinthazi zimakulitsa kwambiri mawotchi ndi matenthedwe azinthu. Kuwonjezera pang'ono kumatha kupititsa patsogolo magwiridwe antchito azinthu zophatikizika, kukulitsa mphamvu zolimba komanso kutalika, komanso kukana kwamafuta ndi kuchedwa kwamoto.

Mapulogalamu Odziwika:

1. Coupling Agent: Amagwiritsidwa ntchito poletsa malawi opanda halogen monga aluminiyamu hydroxide ndi magnesium hydroxide kuti azitha kulumikizana komanso kumamatira pakati pa polyolefin matrix ndi inorganic flame retardants. Kuwonjezera 8% -10% kumatha kupititsa patsogolo mawonekedwe amakina komanso kukana kwamafuta azinthu zophatikizika. Poyerekeza ndi ma coupling agents monga silane, titanate, aluminate, ndi phosphate esters, imapereka kusintha kwabwino pamakina azinthu zamagetsi za polyolefin.
2. Dispersing Promoter: Amagwiritsidwa ntchito mu polyolefin masterbatches, masterbatches oletsa moto, ndi masterbatches owonongeka. Chifukwa cholumikizana mwamphamvu ndi utoto, utoto, ndi zoletsa moto, zimalimbikitsa kubalalitsidwa kwa zowonjezera izi mu utomoni wonyamula wa polyolefin.
3. Bonding Promoter: Ali ndi polarity kwambiri komanso reactivity. Kuonjezera pang'ono kungathandize kwambiri kupenta, kumamatira, komanso kugwirizana kwa zinthuzo.
