1.Definiti na aramid zarbers
Aramidid fiber shine sunan hadin kai ga zaruruwa na kwayoyin cuta.
2.Classification na sumaid fibers
Kiber na Aramidi bisa ga tsarin kwayar halitta za'a iya raba kashi uku: par-aromatic polyamisber fiber, m-aromatic fiber na fiber, molommer fiber. Daga gare su, par-aromatic parlyamamdezoyl) Fibers, poly-benzeicamenicarbode, Inter-Local BenzocamaddBode fiber, Poly-n, nm-tolyl-biss- (Isobenzamide) Terepphthamamaddaide.
3.Ze halaye na aramid zaruruwa
1. Kyakkyawan kayan aikin injin
Ariprosition na arami abu ne mai sauki, karfuka karfi sama da talakawa polyes, da sauransu, elongation na gaba daya da aka yi da daban-daban karkatattun yankuna daban-daban tufafi kariya.
2. Kyakkyawan harshen wuta da juriya
Ilimin oxygen na oxygen (lii) na M-sumaid shine 28, don haka bai ci gaba da ƙonewa ba lokacin da ya bar harshen wuta. Harami na M-aramid an ƙaddara shi ne da tsarin sunadarai, yana sa ya zama mai har abada harshen wuta wanda baya karkatarwa ko rasa flame dinsa tare da lokaci ko wanka. A cikin aramid yana da tsayayye kuma ana iya amfani dashi koyaushe a 205 ° C da kuma kula da babban ƙarfi a yanayin zafi mafi girma fiye da 205 ° C. M-aramid yana da yawan zazzagewa mai yawan lalata kuma baya narkewa ko kuma ya fidda yanayin zafi, amma kawai ya fara char a yanayin zafi mafi girma fiye da 370 ° C.
3. Kayayyakin sunadarai
Baya ga karfi acid da sansanoni, Aramid kusan ba shi da lahani da mai kwayoyin cuta. Rigar da aramid ya kusan daidai da bushewararrun karfin. Tsawon kwanciyar hankali na ruwa mai cike da ruwa ya fi na sauran 'yan fashi na kwayoyin halitta.
Aramid ya kasance mai hankali ga hasken UV. Idan fallasa rana na dogon lokaci, ya rasa ƙarfi da yawa kuma saboda haka za a kiyaye shi tare da Layer na kariya. Wannan Layer kariya dole ne ya iya toshe lalacewar da kasusuwa daga cikin kwandeleton daga hasken UV.
4. Jure juriya
Resistancin theRids aramids ne kwarai. Misali, karkashin 1.72x108rad / s na r-radiation, ƙarfi ya kasance koyaushe.
5. Dorority
Bayan wanke-wanke 100, ƙarfin hawaye na m-aramid yadudduka na iya isa sama da 85% na ƙarfin su na asali. Raunin zazzabi na par-aramids ya fi na Inter-aramids, tare da ci gaba da amfani da amfani da yawan amfani da zafin jiki na -196 ° C to 204 ° C kuma ba zai yanke hukunci ko narkewa a 560 ° C. Mafi mahimmancin halayen param-suma shine babban ƙarfi da kuma ƙarfin ƙarfe sama da sau 2 na ƙarfi na Nylon; Modulus shine 2 ~ sau 3 na babban karfe ko fiber gilashi da sau 10 mai ƙarfi ƙarfi na Nylon masana'antu. Wani yanki na musamman na tsarin ɓangaren ɓangaren ɓangaren ɓangaren ɓangaren ɓangaren ɓangaren ɓangaren ɓangaren ɓangaren ƙuruciya ba, yana inganta riƙe firam ɗin don ƙarfafawa da samfuran sawun. Aramid pickp na fiber na musamman I theramid 1414 Profp, haske mai tsayayya da wasu kayan aiki, mai tsauri, tsayayyen yanayi, matsakaiciya tsawon 2-2.5mm da farfajiya na 8m2 / g. Ana amfani dashi azaman kayan haɓaka na gasket tare da jabu da kuma hatimin aikin ɗan adam da yanayin, m da matsakaiciyar ƙarfi da ƙarfi da kuma Alkali kafofin watsa labarai. An tabbatar da cewa ƙarfin samfurin yayi daidai da 50-60% na Asbestos fiber karfafa samfuran lokacin da ƙasa da 10% na slurry. Ana amfani dashi don ƙarfafa abubuwa da kayan rufe kayayyaki da sauran samfuran da aka ƙera, kuma ana iya amfani dashi azaman madadin kayan kwalliya, mahimmin aikin mai tsayayya da kayan aiki da karfafa kayan aikin.
