nplaim retardant, ib tug ua hauj lwm additive uas muab flammable polymers nplaim retardancy, mas tsim rau nplaim retardant polymer cov ntaub ntawv; Muaj ntau hom nplaim retardants, uas tau muab faib ua cov nplaim hluav taws xob ntxiv thiab cov nplaim hluav taws xob reactive raws li txoj kev siv.
Cov nplaim hluav taws kub hnyiab tau ntxiv rau cov polymer los ntawm kev sib xyaw ua ke los ua kom cov nplaim hluav taws kub nyhiab, thiab cov nplaim hluav taws xob ntxiv feem ntau suav nrog cov nplaim hluav taws kub hnyiab thiab cov nplaim hluav taws tsis zoo, cov nplaim hluav taws halogenated (organochlorides thiab organic bromide) thiab tsis yog-halogen. Organic yog bromine-based, phosphorus-nitrogen-based, nitrogen-based, liab phosphorus thiab cov tebchaw ua tus sawv cev ntawm qee cov nplaim hluav taws, inorganic feem ntau yog antimony trioxide, magnesium hydroxide, aluminium hydroxide, silicon thiab lwm cov nplaim hluav taws kub.
Reactive nplaim retardants koom nyob rau hauv lub polymerization cov tshuaj tiv thaiv raws li ib tug monomer, yog li ntawd lub polymer nws tus kheej muaj cov nplaim retardant Cheebtsam, uas muaj qhov zoo ntawm muaj me ntsis cuam tshuam rau kev ua tau zoo ntawm cov ntaub ntawv polymer thiab cov nplaim retardancy ntev.
