Iimpawu ezintlanu ze-aramid fiber
ilaphu leAramid, elilaphu le-Kevlar, ilaphu le-aramid fiber, ilaphu le-aramid, luhlobo lwelaphu eline-insulation kunye nokugcina ubushushu.Inoluhlu olubanzi lwezicelo kwishishini kunye nokukhuselwa komkhosi.Inezi mpawu ziphambili zilandelayo:
1. Iipropathi ezilungileyo zoomatshini iAramid yipolymer ebhetyebhetye enamandla okuqhawuka okuphezulu kunepolyester eqhelekileyo, umqhaphu, inayiloni, njl., enobude obukhulu, ivakalelo elithambileyo kunye nokujikeleza okuhle, kwaye Inokwenziwa ibe yimisonto esisiseko ye-denier eyahlukeneyo kunye nobude.Kwimisonto eqhelekileyo yelaphu, iintsinga kunye neentsinga zenziwe zibe yimisonto eyahlukeneyo kwaye zilukwe zibe ngamalaphu kunye namalaphu angalukwanga.Emva kokugqiba, inokuhlangabezana neemfuno zempahla yokukhusela kwiinkalo ezahlukeneyo.
2.Ukubuyiswa komlilo okugqwesileyo kunye nokumelana nobushushu.I-Meta-aramids ine-oxygen index (LOI) ekhawulelayo engaphezulu kwe-28 kwaye ngoko ke ayiqhubeki ukutshisa xa ishiya ilangatye.Ukusebenza kwe-flame retardant ye-Newstar® meta-aramid kuxhomekeke kwisakhiwo sayo sekhemikhali, ngoko ke yi-fiber esisigxina ye-flame retardant engayi kunciphisa okanye ilahlekelwe iipropati zayo zokunqanda ilangatye ngenxa yokusebenzisa ixesha kunye nexesha lokuhlamba.I-Newstar® meta-aramid inozinzo olululo lwe-thermal, ingasetyenziswa ngokuqhubekayo kwi-205°C, kwaye isenokugcina amandla aphezulu kumaqondo obushushu angaphezu kwama-205°C.INewstar® meta-aramid inobushushu obuphezulu bokubola kwaye ayiyi kunyibilika okanye inyibilike.Iyancibilika phantsi kweemeko eziphezulu zokushisa.Ikhabhoni iqala kuphela kumaqondo obushushu angaphezu kwama 370°C.
3.Iipropati zeekhemikhali ezizinzileyo i-meta-aramid inokumelana okugqwesileyo kuninzi lweekhemikhali, inokumelana nobuninzi be-acids ye-inorganic concentration ephezulu, kwaye inokumelana kakuhle ne-alkali kubushushu begumbi.
4. Imeta-aramid yokumelana nemitha inokumelana nemitha ebalaseleyo.Ngokomzekelo, phantsi kokuvezwa kwexesha elide kwi-1.2 × 10-2 w / in2 imisebe ye-ultraviolet kunye ne-1.72 × 108rads imisebe ye-gamma, ukuqina kwabo kuhlala kungatshintshi.
5. I-meta-aramid ehlala ixesha elide inika ukukhuhlana okugqwesileyo kunye nokumelana neekhemikhali.Emva kokuhlamba kwe-100, amandla okukrazula amalaphu aphathwe nge-Newstar® meta-aramid asenokufikelela ngaphezulu kwe-85% yamandla okuqala.
