Iimpawu ze-aramid fiber

I-1, iipropati ezilungileyo zoomatshini

Ifayibha yeAramid luhlobo lwepolymer ebhetyebhetye, ukophuka kwayo kuphezulu kunepolyester eqhelekileyo, umqhaphu, inayiloni, njl., ubude bayo bukhulu, umqheba wayo uthambile, kwaye ukujikeleza kwawo kulungile.Inokuveliswa ibe yimicu emifutshane kunye neentsinga ezinezikhanyeli ezahlukeneyo kunye nobude, ezinokuthi zenziwe zibe ngamalaphu kunye namalaphu angalukwanga anezibalo zemisonto ezahlukeneyo kumatshini welaphu jikelele.Emva kokugqiba, inokuhlangabezana neemfuno zempahla yokukhusela kwiinkalo ezahlukeneyo.

2. Ukubuyiswa komlilo okugqwesileyo kunye nokumelana nobushushu.

Ukunciphisa i-oxygen index (LOI) ye-aramid fiber inkulu kune-28, ngoko ayiyi kuqhubeka ivutha xa ishiya ilangatye.Iipropati ze-flame retardant ze-aramid fiber zichongwa yi-chemical structure yayo, ngoko ke i-fiber ehlala i-flame retardant, kunye neempawu zayo zokunqanda ilangatye aziyi kuncitshiswa okanye zilahleke ngenxa yokusetyenziswa kwexesha kunye namaxesha okuhlamba.Ifayibha ye-Aramid inozinzo olululo lwe-thermal, ingasetyenziswa ngokuqhubekayo kwi-300 ℃, kwaye isenokugcina amandla aphezulu kubushushu obungaphezulu kwe-380℃.Ifayibha ye-Aramid inobushushu obuphezulu bokubola, kwaye ayizukunyibilika okanye ithontsize kubushushu obuphezulu, kwaye iyacotha icarbonize xa ubushushu bungaphezulu kwe 427℃.

3. Iimpawu zeekhemikhali ezizinzileyo

Ifayibha ye-Aramid inokumelana okugqwesileyo kuninzi lweekhemikhali, uninzi lwee-asidi ze-inorganic zokugxila okuphezulu kunye nokumelana okuhle kwealkali kwiqondo lobushushu begumbi.

4. Ukumelana nemitha

Ifayibha yeAramid inokumelana nemitha ebalaseleyo.Ngokomzekelo, phantsi kwe-irradiation yexesha elide le-1.2 × 10-2 w / in2 imisebe ye-ultraviolet kunye ne-1.72 × 108rads imisebe ye-gamma, ubukhulu bayo buhlala bungatshintshi.

5. Ukuqina

Ifayibha yeAramid inokumelana nokukhuhlana okugqwesileyo kunye nokumelana neekhemikhali.Emva kwamaxesha ali-100 okuhlanjwa, ukuqhawuka kwentambo, iribhoni okanye ilaphu elisekwe nge-aramid fiber isenokufikelela kwi-85% yamandla okuqala.
