Iimpawu zephepha le-aramid
Uzinzo lwe-thermal oluzinzileyo. Olona phawu lubalaseleyo lwe-aramid 1313 kukumelana nobushushu obuphezulu, obunokusetyenziswa ixesha elide kubushushu obuphezulu be-220 ℃ ngaphandle kokuguga. Iimpawu zayo zombane kunye nezomatshini zingagcinwa ukuya kuthi ga kwiminyaka eyi-10, kwaye ukuzinza kwayo komgangatho kubalaseleyo. Kuma-250 ℃, izinga lokucutheka kwe-thermal yi-1% kuphela; Ukuba sesichengeni sexesha elifutshane kumaqondo obushushu aphezulu angama-300 ℃ akusayi kubangela ukushwabana, ukonakala, ukuthamba, okanye ukunyibilika; Iqala ukubola kuphela kumaqondo obushushu angaphezu kwama-370 ℃; I-Carbonization iqala kuphela malunga ne-400 ℃ - ukuzinza okuphezulu kwe-thermal kunqabile kwiintsinga ze-organic ezikwazi ukumelana nobushushu.
Ukuzingca idangatye. Ipesenti ye-oksijini efunekayo kwisixhobo sokutshisa emoyeni ibizwa ngokuba yi-limited oxygen index, kwaye iphezulu isalathisi se-oksijini ye-oksijini, ngcono ukusebenza kwayo kwe-flame retardant. Ngokuqhelekileyo, umxholo we-oksijini emoyeni ngu-21%, ngelixa umda we-oxygen index ye-aramid 1313 inkulu kune-29%, eyenza i-fiber-retardant fibre. Ke ngoko, ayizukutshisa emoyeni okanye incede ekutshiseni, kwaye ineempawu zokuzicima. Olu phawu lwendalo luvela kulwakhiwo lwalo lwemolekyuli lwenza i-aramid 1313 ilungxe ngokusisigxina idangatye, kungoko yaziwa ngokuba yi "fireproof fiber".
Ukufakelwa kombane okugqwesileyo. I-Aramid 1313 ine-dielectric engaguqukiyo ephantsi kakhulu kwaye amandla ayo endalo edielectric ayenza ikwazi ukugcina ubushushu bombane obugqwesileyo phantsi kobushushu obuphezulu, ubushushu obuphantsi, kunye neemeko zokufuma okuphezulu. Iphepha lokugquma elilungiswe ngalo liyakwazi ukumelana nokwaphuka kwamandla ombane ukuya kuthi ga kwi-40KV/mm, nto leyo eyenza ukuba ibe yeyona nto yamkelwa kwihlabathi liphela.
Uzinzo olugqwesileyo lweekhemikhali. Ubume bemichiza ye-aramid 1313 izinzile ngokungaqhelekanga, imelana nokugqwala kwe-acids ye-inorganic egxininiswe kakhulu kunye nezinye iikhemikhali, kwaye iyamelana ne-hydrolysis kunye ne-steam corrosion.
Iimpawu ezigqwesileyo zoomatshini. I-Aramid 1313 yimpahla yepolymer eguquguqukayo kunye nokuqina okuphantsi kunye nobude obuphezulu, obunika i-spinnability efanayo njengemicu eqhelekileyo. Inokucutshungulwa ibe ngamalaphu ahlukeneyo okanye amalaphu angalukwanga kusetyenziswa oomatshini abajikelezayo abaqhelekileyo, kwaye ayigugi kwaye ixhathisa ukukrazuka, kunye noluhlu olubanzi lwezicelo.
Ukuxhathisa olomeleleyo ngemitha. I-Aramid 1313 enganyangekiyo α、β、χ Ukusebenza kwemitha yemitha kunye nokukhanya kweultraviolet kuhle kakhulu. Ukusebenzisa i-50Kv χ Emva kweeyure ezili-100 zokusasazeka kwemitha, amandla efayibha ahlala kwi-73% yawo yoqobo, ngelixa ipolyester okanye inayiloni sele ijike yaba ngumgubo.
