1. Tsanangudzo yearamid fibers
Aramid faibha izita remubatanidzwa reanonhuwirira polyamide fibres.
2.Kuronga kwearamid fibers
Aramid faibha zvinoenderana nechimiro chemorekuru inogona kukamurwa kuita marudzi matatu: para-aromatic polyamide faibha, inter-aromatic polyamide faibha, anonhuwirira polyamide copolymer faibha. Pakati pawo, para-aromatic polyamide fibers yakakamurwa kuita poly-phenylamide (poly-p-aminobenzoyl) fibers, poly-benzenedicarboxamide terephthalamide fibers, inter-position benzodicarbonyl terephthalamide fibers yakakamurwa kuita poly-m-tolyl terephthalamide fibers, poly-N,Nbim-tolyphthalamide) fibers (Nbim-tolyphthalamide).
3.Zvinhu zvearamid fibers
1. Good mechanical properties
Interposition aramid ipolymer inochinjika, inopwanya simba rakakwira kupfuura yakajairwa polyester, donje, naironi, nezvimwewo, kureba kwakakura, kupfava kusvika pakubata, kutenderera kwakanaka, kunogona kugadzirwa muhutete hwakasiyana, hurefu hwetambo pfupi nemafilaments, kazhinji machira akagadzirwa neshinda dzakasiyana akarukwa kuita machira, asiri akarukwa akasiyana, nzvimbo dzinodiwa kuti dzikwane machira.
2. Yakanakisa murazvo uye kupisa kupisa
Iyo inomisa oxygen index (LOI) ye m-aramid ndeye makumi maviri nemasere, saka hairambe ichipisa kana ichinge yabva mumurazvo. Iyo m-aramid inodzoreredza zvimiro zvem-aramid inotemerwa neyayo kemikari chimiro, ichiita kuti ive zvachose murazvo unodzoreredza faibha isingadzikisi kana kurasikirwa yayo inodzoreredza murazvo nenguva kana kugeza. Iyo m-aramid inogadzikana uye inogona kushandiswa nguva dzose pa205 ° C uye inochengetedza simba repamusoro pane tembiricha inodarika 205 ° C. Iyo m-aramid ine tembiricha yekuora yakanyanya uye hainyungudike kana kudonha patembiricha yakakwira, asi inongotanga kupisa patembiricha inodarika 370°C.
3. Yakagadzikana makemikari zvinhu
Pamusoro peasidhi yakasimba uye mabhesi, aramid haitombobatike neorganic solvents nemafuta. Simba rakanyorova re aramid rinenge rakaenzana nekuoma kwesimba. Kugadzikana kwemhute yemvura yakazara iri nani pane yemamwe organic fiber.
Aramid inonyatsonzwa kune UV chiedza. Kana yakasvibiswa nezuva kwenguva yakareba, inorasikirwa nesimba rakawanda uye naizvozvo inofanira kuchengetedzwa nevhavha yekudzivirira. Iyi dura rekudzivirira inofanirwa kukwanisa kuvhara kukuvadzwa kwearamid skeleton kubva kuUV mwenje.
4. Radiation resistance
Kupokana nemwaranzi ye interposition aramids yakanaka. Semuenzaniso, pasi pe1.72x108rad/s ye-r-radiation, simba rinoramba riripo.
5. Kugara kwenguva refu
Mushure mekugeza zana, simba rekubvaruka remachira m-aramid richiri kugona kusvika kupfuura 85% yesimba rawo rekutanga. Tembiricha yekudzivirira yepara-aramidhi yakakwirira kudarika iyo ye-inter-aramid, ine inoenderera kushandiswa tembiricha ye -196 ° C kusvika 204 ° C uye haina kuora kana kunyungudika pa560 ° C. Chimiro chinonyanya kukosha chepara-aramid isimba rayo rakakwirira uye yakakwirira modulus, simba rayo rinopfuura 25g / dan, iyo 5 ~ 6 nguva dzesimbi yepamusoro, 3 nguva dzegirazi fiber uye 2 nguva dzepamusoro simba nylon industrial yarn; modulus yayo ndeye 2 ~ 3 nguva dzepamusoro simbi kana girazi faibha uye 10 nguva dzepamusoro simba naironi maindasitiri shinda. Iyo yakasarudzika pamusoro pechimiro cheiyo aramid pulp, iyo inowanikwa nepamusoro fibrillation yearamid fibres, inovandudza zvakanyanya kubata kwekomboni uye saka yakanakira senge inosimbisa fiber yekukwenya uye kuvhara zvigadzirwa. Aramid Pulp Hexagonal Special Fiber I Aramid 1414 Pulp, yakareruka yeyero inoyerera, yakapfava, ine akawanda mapuropa, yakakwira simba, yakanaka dimensional kugadzikana, isina-brittle, yakakwirira tembiricha inodzivirira, inodzivirira corrosion, yakaoma, yakaderera shrinkage, yakanaka abrasion kuramba, yakakura nzvimbo, yakanaka kubatanidza, avhareji yeavhareji yehunyoro hurefu hwezvinhu 8% inodzoserwa nehurefu hwezvinhu. 2-2.5mm uye nzvimbo yepamusoro ye8m2/g. Inoshandiswa segasket reinforcement material ine simba rekusimudzira uye kuisa chisimbiso, uye haikuvadzi hutano hwevanhu uye nharaunda, uye inogona kushandiswa kuvhara mumvura, mafuta, zvinoshamisa uye zvepakati simba asidhi uye alkali media. Izvo zvave zvichiratidzwa kuti kusimba kwechigadzirwa kwakaenzana ne50-60% yeasbestos fiber yakasimbiswa zvigadzirwa kana isingasviki 10% ye slurry yakawedzerwa. Inoshandiswa kusimbisa kukweshera uye kuisa chisimbiso uye zvimwe zvigadzirwa zvinogadzirwa, uye inogona kushandiswa seimwe nzira kune asbestos yekukwesha yekuisa chisimbiso zvinhu, yakanyanya kuita kupisa inodzivirira kupisa bepa uye yakasimbiswa inoumbwa zvinhu.
