Njirimara nke eriri aramid

1, ezigbo igwe akụrụngwa

Aramid fiber bụ ụdị polymer na-agbanwe agbanwe, ike na-agbaji ya dị elu karịa polyester nkịtị, owu, naịlọn, wdg, elongation ya dị ukwuu, aka ya dị nro, na spinnability ya dị mma.Enwere ike ịmepụta ya n'ime obere eriri na filament nwere ihe ngọnarị dị iche iche na ogologo ogologo, nke a ga-eme ka ọ bụrụ akwa akwa na akwa na-abụghị nke nwere ọnụ ọgụgụ yarn dị iche iche na igwe textile n'ozuzu.Mgbe emechara, ọ nwere ike izute ihe ndị a chọrọ nke uwe nchebe na mpaghara dị iche iche.

2. Ezigbo ọkụ retardancy na okpomọkụ na-eguzogide.

Mbelata ikuku oxygen (LOI) nke eriri aramid karịrị 28, yabụ na ọ gaghị aga n'ihu na-ere ọkụ mgbe ọ na-ahapụ ọkụ.The ire retardant Njirimara nke aramid eriri na-ekpebisi ike site na ya chemical Ọdịdị, ya mere, ọ bụ a na-adịgide adịgide ire ọkụ retardant eriri, na ire ere retardant Njirimara agaghị ebelata ma ọ bụ na-efunahụ n'ihi na ojiji oge na oge ịsa.Aramid eriri nwere ezi thermal kwụsie ike, ike ga-eji na-aga n'ihu na 300 ℃, na ka nwere ike ịnọgide na-enwe elu ike na elu okpomọkụ karịa 380 ℃.Aramid eriri nwere a elu decomposition okpomọkụ, na ọ gaghị agbaze ma ọ bụ ntapu na elu okpomọkụ, na ọ ga-eji nwayọọ nwayọọ carbonize mgbe okpomọkụ dị elu karịa 427 ℃.

3. Njirimara kemịkalụ kwụsiri ike

Fiber Aramid nwere ezigbo nguzogide nke ọtụtụ kemịkalụ, acid inorganic kachasị elu yana ezigbo nguzogide alkali na ụlọ okpomọkụ.

4. Nguzogide radieshon

Aramid fiber nwere ezigbo ihe mgbochi radieshon.Dịka ọmụmaatụ, n'okpuru irradiation ogologo oge nke 1.2 × 10-2 w / in2 ultraviolet radieshon na 1.72 × 108rads gamma ụzarị, ike ya ka na-agbanwe agbanwe.

5. Ogologo oge

Aramid eriri nwere magburu onwe esemokwu nguzogide na chemical iguzogide.Mgbe 100 ugboro ịsachara, ike na-agbaji nke eriri, rịbọn ma ọ bụ akwa nke aramid fiber na-edozi nwere ike iru 85% nke ike mbụ.
