Igama leMathiriyeli: I-Aramid Fiber
Indawo yosetyenziso
Ifayibha ye-Aramid luhlobo olutsha lwe-high-tech fiber synthetic, amandla aphezulu, imodyuli ephezulu kunye nokumelana nobushushu obuphezulu, ukuxhathisa kwe-asidi kunye ne-alkali, ubunzima obulula, iipropathi ezigqwesileyo, ezinje nge-5 ~ 6 amaxesha ocingo lwentsimbi kumandla ayo, Imodyuli yocingo lwensimbi okanye i-fiber glass 2 ~ 3 amaxesha, ukuqina ngamaxesha angama-2 ocingo, kunye nobunzima malunga ne-1/5 yocingo lwensimbi, ubushushu be-560 degrees, musa ukuphuka, musa ukunyibilika.
Ine-insulation elungileyo kunye ne-anti-aging properties, kwaye inomjikelo wobomi obude.Ukufunyanwa kwefayibha ye-aramid kuthathwa njengenkqubo yembali ebaluleke kakhulu kwihlabathi lezinto ezibonakalayo.
Ifayibha yeAramid yinto ebalulekileyo yomkhosi wokhuselo lwelizwe.Ukuze kuhlangatyezwane neemfuno zemfazwe yanamhlanje, ngoku, iibhatyi zembumbulu zamazwe aphuhlileyo anjengeUnited States neUnited Kingdom zenziwe nge-aramid fiber.Ukukhanya kweebhatyi ze-aramid ze-fiber bulletproof kunye nezigcina-ntloko ziphucula ngempumelelo isakhono sokusabela ngokukhawuleza kunye nobungozi bemikhosi yomkhosi.KwiMfazwe yeGulf, iinqwelomoya zaseMelika kunye nezaseFransi zasebenzisa inani elikhulu lezinto ezihlanganisiweyo ze-aramid.Ukongeza kwizicelo zomkhosi, njengesixhobo sobugcisa obuphezulu se-fiber sisetyenziswe ngokubanzi kwi-aerospace, oomatshini kunye nombane, ukwakhiwa, iimoto, iimpahla zemidlalo kunye neminye imiba yoqoqosho lwelizwe.Ngokubhekiselele kwinqwelomoya kunye ne-aerospace, i-aramid fiber igcina amandla amaninzi ngenxa yobunzima bayo kunye namandla aphezulu.Ngokutsho kwedatha yamazwe ngamazwe, ngexesha lokuqaliswa kwenkqubo ye-spacecraft, konke ukunciphisa ubunzima be-1 kg kuthetha ukunciphisa iindleko ze-1 yezigidi zeedola zase-US.Ukongeza, uphuhliso olukhawulezayo lwesayensi kunye netekhnoloji luvula indawo entsha yoluntu kwi-Aramid.Kuxelwe ukuba ngoku, malunga ne-7 ~ 8% yeemveliso ze-aramid zisetyenziselwa i-flak jackets, izigcina-ntloko, njl., kwaye malunga ne-40% zisetyenziselwa izinto ze-aerospace kunye nezixhobo zemidlalo.Izinto zamathambo eTire, imathiriyeli yebhanti yokuhambisa kunye neminye imiba emalunga ne-20%, kunye nentambo yamandla aphezulu kunye neminye imiba emalunga ne-13%.
Iindidi kunye nemisebenzi ye-Aramid fiber: I-Para-Aramid fiber (PPTA) kunye ne-interaromatic amide fiber (PMIA)
Emva kophuhliso oluyimpumelelo kunye noshishino lwefayibha ye-aramid nguDuPont ngeminyaka yoo-1960, ngaphezulu kweminyaka engama-30, ifayibha ye-aramid iye yadlula kwinkqubo yotshintsho ukusuka kwizixhobo zobuchule zomkhosi ukuya kwizinto zasekuhlaleni, kwaye ixabiso layo liye lancitshiswa phantse ngesiqingatha.Okwangoku, iifayibha ze-aramid zangaphandle ziyakhula zombini kwinqanaba lophando kunye nophuhliso kunye nemveliso yesikali.Kwintsimi yokuveliswa kwefayibha ye-aramid, ifayibha ye-aramide yeyona nto ikhula ngokukhawuleza, kunye nomthamo wayo wemveliso ugxile eJapan, eUnited States naseYurophu.Ngokomzekelo, i-Kevlar evela kwi-dupont, i-Twaron fiber evela e-Akzo Nobel (ihlanganiswe neTeren), i-Technora fiber evela e-TeREN yaseJapan, i-Terlon fiber evela eRashiya, njl.
Kukho iNomex, iConex, iFenelon fiber njalo njalo.UDupont waseMelika unguvulindlela kuphuhliso lwe-aramid.Ibeka kuqala kwihlabathi kungakhathaliseki ukuba kuphando kunye nophuhliso lweemveliso ezintsha, imithetho yemveliso kunye nesabelo semarike.Okwangoku, iifayibha zayo ze-Kevlar zineebrendi ezingaphezu kwe-10, ezifana ne-Kevlar 1 49 kunye ne-Kevlar 29, kwaye i-brand nganye ineenkcukacha ezininzi.UDupont ubhengeze kulo nyaka uphelileyo ukuba iyakwandisa amandla ayo okuvelisa iKevlar, kwaye iprojekthi yokwandisa kulindeleke ukuba igqitywe ekupheleni kwalo nyaka.Akunakugqitywa, amashishini aziwayo okuvelisa i-aramid afana ne-Di Ren kunye ne-Hearst baye bandisa imveliso okanye badibanisa imikhosi, kwaye baphonononga ngenkuthalo imarike, benethemba lokuba ngumbutho omtsha kule shishini lokuphuma kwelanga.
Inkampani yaseJamani iAcordis isandula ukuvelisa iimveliso ze-ultrafine contrapuntal aron (Twaron) ezisebenza kakhulu, ezingatshiyo okanye zinyibilike, kwaye zinamandla aphezulu kunye nokumelana okukhulu nokusika, ezisetyenziswa ikakhulu kwimveliso yamalaphu agqunyiweyo nangagqunywanga, iimveliso ezinithiweyo kunye nenaliti ezivakeleyo kunye nezinye eziphakamileyo. -ubushushu kunye nokumelana nokusika kuzo zonke iintlobo zempahla yengubo kunye nempahla.Ukulunga kwe-Twaron isilika ebhityileyo kakhulu yi-60% kuphela ye-arylon ye-counterpoint edla ngokusetyenziswa kwiisuti zokhuseleko emsebenzini, kwaye ingasetyenziselwa ukwenza iiglavu.· Ikhono layo lokuchasa ukusika lingaphuculwa nge-10%.Ingasetyenziselwa ukuvelisa amalaphu alukiweyo kunye neemveliso ezinithiweyo, ngokuziva kwesandla esithambileyo kunye nokusetyenziswa ngokukhululekileyo.Iigloves ezichasene nokusika iTwaron zisetyenziswa ikakhulu kushishino lwemoto, ishishini leglasi kunye namalungu entsimbi.Zisenokusetyenziswa kwishishini lehlathi ukuvelisa iimveliso zokukhusela umlenze kunye nokubonelela ngezixhobo zokulwa nomonakalo kwishishini lezothutho zikawonkewonke.
Ipropathi ye-Twaron ye-fire retardant ingasetyenziselwa ukubonelela abacimi bomlilo ngeesuti zokukhusela kunye neengubo ezizivayo, kunye namasebe okusebenza ngobushushu obuphezulu obufana nokuphosa, iziko, umzi-mveliso weglasi, njl.Le fiber yokusebenza iphezulu ingasetyenziselwa ukwenza amatayara eemoto, iipayipi zokupholisa, i-V-belt kunye nabanye oomatshini, iintambo zefiber optical kunye ne-bulletproof vests kunye nezinye izixhobo zokukhusela, kodwa inokutshintsha indawo ye-asbestos njengezinto zokukhuhla kunye nezinto zokutywina.
Imfuno yeMarike
Ngokwezibalo, imfuno yehlabathi iyonke ye-aramid fiber yi-360,000 yeetoni / ngonyaka kwi-2001, kwaye iya kufikelela kwiitoni ze-500,000 / ngonyaka ngo-2005. Imfuno yehlabathi jikelele ye-aramid fiber iyanda, kunye nefayibha ye-aramid, njengefayibha entsha yokusebenza okuphezulu. , ingene kwixesha lophuhliso olukhawulezayo.
