Chosinthira Zinthu Zachingwe Chopanda Moto Chosagwiritsa Ntchito Halogen

Chosinthira Zinthu Zachingwe Chopanda Moto Chosagwiritsa Ntchito Halogen

Ndi kupita patsogolo kwa ukadaulo, pakufunika chitetezo ndi kudalirika kwakukulu m'malo otsekedwa komanso okhala ndi anthu ambiri monga masiteshoni a sitima zapansi panthaka, nyumba zazitali, komanso malo ofunikira kwambiri monga sitima ndi malo opangira magetsi a nyukiliya. Chifukwa chake, pakufunika kwambiri kupanga mitundu yatsopano ya zingwe zokhala ndi utsi wochepa, zopanda halogen, komanso zoletsa moto. Kumayambiriro kwa zaka za m'ma 1980, mayiko otukuka padziko lonse lapansi adayamba kufufuza ndikupanga zipangizo ndi zingwe zopanda halogen zoletsa moto. Zingwe zopanda halogen zoletsa moto zakhala zikugwiritsidwa ntchito mwachangu komanso kugwiritsidwa ntchito kwambiri. Ku China, opanga mawaya ndi zingwe m'mizinda monga Shanghai, Shenyang, Suzhou, Sichuan, Xiangtan, ndi Wuxi apanga zingwe zamagetsi zoletsa moto, zingwe zosinthika zofukula rabala, zingwe zotchingira zombo zotchingira moto, ndi zina zokhudzana nazo.

Zosintha zimagwiritsidwa ntchito mu zipangizo za chingwe zodzaza ndi halogen zopanda moto, monga aluminiyamu hydroxide ndi magnesium hydroxide, kuti zigwirizane bwino ndi kugwirizana pakati pa polyolefin matrix ndi zinthu zoletsa moto zosapangidwa ndi organic. Zimawonjezera kufalikira ndi kugwirizana kwa aluminiyamu hydroxide ndi magnesium hydroxide, motero zimawonjezera kuchedwa kwa moto kwa zinthu za chingwe, kuchepetsa utsi, kutulutsa utsi, kutulutsa kutentha, ndi kupanga carbon monoxide, kuwonjezera index ya okosijeni, ndikuwonjezera kukana kwa madontho. Zosinthazi zimawonjezera kwambiri mphamvu za makina ndi kutentha kwa zinthuzo. Kuwonjezera pang'ono kungathandize kwambiri magwiridwe antchito a makina a zinthu zophatikizana, kuwonjezera mphamvu yolimba ndi kutalika, komanso kukana kutentha ndi kukana kwa moto.

Mapulogalamu Ofala:

1. Cholumikizira: Chimagwiritsidwa ntchito pa zinthu zoletsa moto zopanda halogen monga aluminiyamu hydroxide ndi magnesium hydroxide kuti chigwirizane bwino ndi kugwirizana pakati pa polyolefin matrix ndi zinthu zoletsa moto zopanda chilengedwe. Kuwonjezera 8%–10% kungapangitse kuti zinthu zophatikizana zikhale bwino komanso kuti zinthuzo zikhale zolimba. Poyerekeza ndi zinthu zolumikizirana monga silane, titanate, aluminate, ndi phosphate esters, zimapangitsa kuti zinthu zolumikizirana za polyolefin zizikhala bwino.
2. Chothandizira Kufalitsa: Chimagwiritsidwa ntchito mu polyolefin masterbatches, masterbatches zoletsa moto, ndi masterbatches zowononga. Chifukwa cha kuyanjana kwake kwakukulu ndi utoto, utoto, ndi zoletsa moto, chimalimbikitsa kufalikira kwa zowonjezera izi mu polyolefin carrier resin.
3. Chothandizira Kugwirizanitsa: Chili ndi polarity yayikulu komanso reactivity. Kuwonjezera pang'ono kungathandize kwambiri kuti utoto ukhale wosavuta, womata, komanso wogwirizana ndi zinthuzo.
