1.Ma'anar aramid fibers
Fiber Aramid shine sunan gamayya don filayen polyamide aromatic.
2.Classification na aramid zaruruwa
Aramid fiber bisa ga tsarin kwayoyin za a iya raba uku iri: para-aromatic polyamide fiber, inter-aromatic polyamide fiber, aromatic polyamide copolymer fiber. Daga cikin su, an raba filaye na polyamide para-aromatic zuwa poly-phenylamide (poly-p-aminobenzoyl) zaruruwa, poly-benzenedicarboxamide terephthalamide fibers, matsakaicin matsayi benzodicarbonyl terephthalamide fibers an raba su zuwa poly-m-tolyl terephthalamide fibers, poly-N. Nm-tolyl-bis- (isobenzamide) terephthalamide fibers.

Interposition aramid ne m polymer, karya ƙarfi mafi girma fiye da talakawa polyester, auduga, nailan, da dai sauransu, elongation ne ya fi girma, taushi ga tabawa, mai kyau spinnability, za a iya samar a cikin daban-daban slenderness, tsawon gajeren zaruruwa da filaments, a general yadi. kayan aikin da aka yi da nau'in yarn daban-daban da aka saka a cikin yadudduka, kayan da ba a saka ba, bayan kammalawa, don biyan bukatun wurare daban-daban na tufafin kariya.
2. Kyakkyawan harshen wuta da juriya na zafi
Ƙayyadadden ma'aunin iskar oxygen (LOI) na m-aramid shine 28, don haka baya ci gaba da ƙonewa lokacin da ya bar harshen wuta. Abubuwan da ke hana harshen wuta na m-aramid an ƙaddara su ta hanyar tsarin sinadarai nasa, yana mai da shi fiber mai riƙe harshen wuta na dindindin wanda ba ya ƙasƙantar da shi ko rasa kaddarorinsa na riƙewar wuta tare da lokaci ko wankewa. M-aramid yana da kwanciyar hankali kuma ana iya amfani dashi akai-akai a 205 ° C kuma yana da ƙarfi a yanayin zafi sama da 205 ° C. M-aramid yana da zafi mai girma kuma baya narke ko digo a yanayin zafi mai zafi, amma yana farawa ne kawai a yanayin zafi sama da 370°C.
3. Stable sunadarai Properties
Bugu da ƙari ga acid mai ƙarfi da sansanonin, aramid kusan ba shi da tasiri ta hanyar kaushi da mai. Ƙarfin rigar aramid kusan daidai yake da ƙarfin bushewa. Zaman lafiyar tururi mai cike da ruwa ya fi na sauran filayen halitta.
Aramid yana da kusanci da hasken UV. Idan an fallasa shi zuwa rana na dogon lokaci, yana rasa ƙarfi sosai don haka ya kamata a kiyaye shi tare da kariya mai kariya. Dole ne wannan Layer na kariya ya iya toshe lalacewa ga kwarangwal na aramid daga hasken UV.
4. Juriyar Radiation

5. Dorewa
Bayan wankewa 100, ƙarfin yagayen yadudduka na m-aramid na iya kaiwa sama da kashi 85% na ƙarfinsu na asali. Juriya na zafin jiki na para-aramids ya fi na inter-aramids, tare da ci gaba da amfani da zafin jiki na -196 ° C zuwa 204 ° C kuma babu lalacewa ko narkewa a 560 ° C. Mafi mahimmancin halayen para-aramid shine babban ƙarfinsa da ma'auni mai girma, ƙarfinsa ya fi 25g / dan, wanda shine 5 ~ 6 sau na babban ingancin karfe, 3 sau na gilashin fiber da 2 sau na high ƙarfi nailan yarn masana'antu. ; Modull ɗin sa shine sau 2 ~ 3 na babban ingancin ƙarfe ko fiber gilashi da sau 10 na ƙarfin ƙarfin nailan masana'anta. Tsarin tsari na musamman na ɓangaren litattafan almara, wanda aka samu ta hanyar fibrillation na fibrillation na aramid fibers, yana inganta haɓakar fili da yawa kuma saboda haka yana da kyau a matsayin fiber mai ƙarfafawa don ƙaddamarwa da samfurori. Aramid Pulp Hexagonal Special Fiber I Aramid 1414 ɓangaren litattafan almara, launin rawaya mai haske, mai laushi, tare da ɗimbin plumes, babban ƙarfi, kwanciyar hankali mai kyau, mara karko, babban zafin jiki, juriya mai lalata, tauri, ƙarancin raguwa, juriya mai kyau, babban yanki. , Kyakkyawan haɗin gwiwa tare da wasu kayan, kayan haɓakawa tare da dawowar danshi na 8%, matsakaicin tsayi na 2-2.5mm da yanki na 8m2 / g. Ana amfani da shi azaman kayan ƙarfafa gasket tare da kyakkyawan juriya da aikin rufewa, kuma ba shi da lahani ga lafiyar ɗan adam da muhalli, kuma ana iya amfani dashi don rufewa a cikin ruwa, mai, baƙin ƙarfe da matsakaicin ƙarfi acid da alkali. An tabbatar da cewa ƙarfin samfurin yana daidai da 50-60% na asbestos fiber ƙarfafa kayayyakin lokacin da aka ƙara kasa da 10% na slurry. Ana amfani da shi don ƙarfafa juzu'i da kayan rufewa da sauran samfuran da aka ƙera, kuma ana iya amfani da su azaman madadin asbestos don kayan rufewar gogayya, takarda mai jure zafi mai ƙarfi da ƙarfafa kayan haɗin gwiwa.
