Para-aramid PPTA FR Staple Fiber Pulp yeBulletproof Ballistic Armor yakafanana neKevlar, Twaron, Technora Fiber
Iyo Para-aramid fiber (PPTA) yeAopoly inogadzirwa neiyo liquid crystal spinning tekinoroji kubva kune yakasimba tsvimbo-yakafanana macromolecules (PPTA) polymerized ne terephthaloyl chloride (TCL) uye p-phenylenediamine (PPD) mhinduro.Para-aramid ine zvinoshamisa zvimiro zvesimba rakakwirira, yakakwira modulus, yakakwirira tembiricha kuramba uye murazvo kuramba.Iyo ine mabhenefiti eiyo yakaderera hama density, kuneta kuramba, kubvarura uye shear kuramba uye dimentional kugadzikana.Iko kusanganiswa kweaya akasiyana zvivakwa kunotungamira para-aramid kuve yakanyanya kuita faibha ine yakakura yeduput munyika, iyo mitatu yepamusoro-inoshanda fiber uye "synthetic waya".Inonyanya kushandiswa kune yakakwira performance composite, dziviriro yemunhu, zvemagetsi kutaurirana, zvekufambisa uye zvekupedzisira-mwenje zvinotsigira zvinhu, nezvimwe.
Product Properties
◎ Kusimba Kwakakwirira: Rashiyo yehuremu/kusimba i5 ~ 6 nguva dzewaya yesimbi, 3 nguva dzegirazi fiber uye 2 nguva dzenaironi yakasimba.
◎ High Modulus: Reshiyo yehuremu/modulus inguva nhatu dzewaya yesimbi, 2 nguva dzegirazi faibha uye kagumi dzenaironi ine simba guru.
◎ Heat Resistance: Haina kuora kana kunyunguduka pa500 ℃ uye inogona kushandiswa kuenderera kubva -196 ℃ kusvika 204 ℃.Inochengeta 95% simba mushure me500hus kuratidzwa pasi pe160 ℃ uye inochengeta 75% simba mushure me100hrs kuratidzwa pasi pe200 ℃.
Main Applications
Geotechnique & kongiri sturcture: Para-aramid fiber inoshandiswa kugadzirisa kukuvadzwa kwekongiri chimiro.Aramid fibers inoputirwa pamakoni akasimbiswa obva aenderera mberi nekuisa resin impregnation uye kurapa iyo inoshandiswa kugadzirisa zvivakwa zvekare uye zvakakanganisika uyezve kusimbisa chimiro (semuenzaniso, kusangana nezvinodiwa zvekudzivirira kwekudengenyeka).
Zvekusimbisa: optic fiber uye tambo, matayi uye zvigadzirwa zverabha, mafuta akapfava naan, tembiricha yepamusoro uye pombi yekumanikidza.
Bulletproof Zvigadzirwa: Dziviriro yekuchengetedza: bulletproof vest/helmeti, arc-proof zvipfeko, lightweight composite nhumbi dzokurwa.
Anti-kucheka zvigadzirwa: mune zvakajairwa maindasitiri maitiro, vashandi vanowanzobata mipendero yakapinza kana zvinhu zvinopisa, zvinosanganisira girazi kana simbi.Kune mabasa akadaro eindasitiri, magirovhosi ekudzivirira ari pachena anodiwa.
Para-aramid fiber kuchengetedza magurovhosi anopa vashandisi dhigirii yakakura yehunyoro, asi zvakare inobatanidza zvakanakisa dziviriro, nyaradzo uye nyore kushandisa.Para-aramid inogonawo kupa kuchengetedzwa kwemakumbo kune vashandi vemasango, uye inogonawo kushandiswa semucheka usingakuvadzi wezvigaro zvebhazi nechitima.
Composite zvinhu: yakasimbiswa inoumbwa zvinhu zvine zvakanyanyisa zvinodikanwa zvekureruka uye kukuvara kushivirira, uye para-aramid fiber inoita basa rakakosha mune izvi.Para-aramid yakazvipira kupa mhinduro dzepamusoro-soro kunzvimbo dzinoda zvinhu zvakaumbwa, zvinosanganisira marine and aerospace engineering, civil engineering, ground transport, engineering plastics, mota mota/yacht shells zvemitambo.
Fruction uye zvisimbiso zvekushandisa: Kuwedzera aramid pulp uye yakachekwa fiber inogona kuvandudza mashandiro emabrake pads, brake pad linings, uye clutch friction plates, nekudaro kuwedzera hupenyu hwechigadzirwa nekuvandudza kutyaira kunyaradza.
Kunyanya maererano nekunyaradza, aramid pulp yakaita mupiro mukuru mukuderedza ruzha, vibration uye hutsinye (NVH).Izvo zvakavakirwa pane izvi zvakasarudzika zvivakwa izvo aramid pulp yave chinhu chesarudzo kune vanogadzira zvigadzirwa kutenderera pasirese.Nekuda kwekudzikisira kukweshera kwemabhureki pads, zvinodikanwa zvekushanda kwezvinhu zvinoshandiswa zvinowedzera kusimbiswa-kuita kwakanaka kwazvo kwearamid fiber zvigadzirwa zvinoita basa zvakare pano.
Midziyo yemitambo uye nezvimwe: tambo, kite tambo, gorofu makirabhu, sledges, nezvimwe.
