Tsib yam ntxwv ntawm aramid fiber
Aramid ntaub, uas yog Kevlar daim ntaub, aramid fiber ntau daim ntaub, aramid ntaub, yog ib hom ntaub nrog rwb thaiv tsev thiab kub txuag.Nws muaj ntau yam kev siv hauv kev lag luam thiab kev tiv thaiv tub rog.Nws muaj cov yam ntxwv tseem ceeb hauv qab no:
1. Cov khoom siv zoo Aramid yog cov khoom siv tau yooj yim nrog lub zog tawg ntau dua li cov polyester zoo tib yam, paj rwb, nylon, thiab lwm yam, nrog ntau dua elongation, mos xav thiab zoo spinnability, thiab tuaj yeem ua rau hauv cov fibers staple ntawm qhov sib txawv thiab ntev.Hauv cov tshuab textile zoo tib yam, fibers thiab filaments tau ua rau cov xov paj sib txawv thiab woven rau hauv cov ntaub thiab cov ntaub tsis-woven.Tom qab ua tiav, nws tuaj yeem ua tau raws li cov kev cai ntawm cov khaub ncaws tiv thaiv hauv ntau qhov chaw.
2.Zoo heev nplaim retardancy thiab kub tsis kam.Meta-aramids muaj qhov txwv qhov ntsuas oxygen (LOI) ntau dua 28 thiab yog li tsis txhob hlawv ntxiv thaum tawm hauv nplaim taws.Cov nplaim retardant kev ua tau zoo ntawm Newstar® meta-aramid nyob ntawm nws tus kheej cov qauv tshuaj, yog li nws yog cov nplaim hluav taws xob ruaj khov uas yuav tsis txo lossis poob nws cov nplaim hluav taws xob vim siv sijhawm thiab sijhawm ntxuav.Newstar® meta-aramid muaj qhov zoo thermal stability, tuaj yeem siv tsis tu ncua ntawm 205 ° C, thiab tseem tuaj yeem tuav lub zog siab ntawm qhov kub siab tshaj 205 ° C.Newstar® meta-aramid muaj qhov kub thiab txias dua thiab yuav tsis yaj lossis yaj.Melts nyob rau hauv qhov kub thiab txias.Carbonization tsuas yog pib ntawm qhov kub siab tshaj 370 ° C.
3.Cov khoom lag luam ruaj khov meta-aramid muaj cov tshuaj tiv thaiv zoo rau feem ntau cov tshuaj, tuaj yeem tiv taus feem ntau cov kua qaub inorganic acids, thiab muaj alkali tsis kam ntawm chav tsev kub.
4. Radiation resistance meta-aramid muaj hluav taws xob zoo heev.Piv txwv li, nyob rau hauv lub sij hawm ntev raug rau 1.2 × 10-2 w / in2 ultraviolet rays thiab 1.72 × 108rads gamma rays, lawv qhov kev siv tseem tsis hloov.
5. Ntev ntev meta-aramid muaj kev sib txhuam zoo heev thiab tshuaj tiv thaiv.Tom qab 100 ntxuav, lub zog tsim kua muag ntawm cov ntaub kho nrog Newstar® meta-aramid tseem tuaj yeem ncav cuag ntau dua 85% ntawm lub zog qub.
