1.Tlhaloso ea likhoele tsa aramid
Fibre ea Aramid ke lebitso le kopaneng la likhoele tse nkhang hamonate tsa polyamide.
2.Sehlopha sa likhoele tsa aramid
Fiber ea Aramid ho latela sebopeho sa limolek'hule e ka aroloa ka mefuta e meraro: fiber ea para-aromatic polyamide, fiber e nkhang hamonate ea polyamide, fiber e nkhang hamonate ea polyamide copolymer. Har'a tsona, likhoele tsa para-aromatic polyamide li arotsoe ka likhoele tsa poly-phenylamide (poly-p-aminobenzoyl), poly-benzenedicarboxamide terephthalamide fibers, inter-position benzodicarbonyl terephthalamide fibers li arotsoe ka likhoele tsa poly-m-tolyl terephthalamide, poly-N, Nm-tolyl-bis-(isobenzamide) terephthalamide fibers.
3.Litšobotsi tsa likhoele tsa aramid
1. Lintho tse ntle tsa mechine
Interposition aramid ke polymer e tenyetsehang, matla a robehang a phahame ho feta polyester e tloaelehileng, k'hothone, nylon, joalo-joalo, elongation e kholoanyane, e bonolo ho ea ho e ts'oaroang, e ntle ea spinnability, e ka hlahisoa ka mefuta e fapaneng ea slenderness, bolelele ba likhoele tse khutšoane le likhoele, ka kakaretso masela. Mechini e entsoeng ka likhoele tse fapaneng e bala e lohiloeng ka masela, masela a sa lohiloeng, kamora ho qeta, ho fihlela litlhoko tsa libaka tse fapaneng tsa liaparo tse sireletsang.
2. E babatsehang lelakabe le mocheso ho hanyetsa
Lenane la oksijene e fokolang (LOI) ea m-aramid ke 28, kahoo ha e tsoele pele ho tuka ha e tloha lelakabe. Thepa e thibelang lelakabe la m-aramid e khethoa ke sebopeho sa eona sa lik'hemik'hale, e leng se etsang hore e be tlhale e thibelang lelakabe ka ho sa feleng e sa senyeheng kapa e lahleheloang ke matla a eona a ho thibela mollo ka nako kapa ho hlatsoa. M-aramid e tsitsitse ka mocheso mme e ka sebediswa kamehla ho 205°C mme e boloka matla a phahameng mochesong o fetang 205°C. M-aramid e na le mocheso o phahameng wa ho bola mme ha e qhibidihe kapa ho rotha ka dithempereichara tse phahameng, empa e qala feela ho tjhesa mocheso o fetang 370°C.
3. Lintho tse tsitsitseng tsa lik'hemik'hale
Ho phaella ho li-acids tse matla le li-bases, aramid ha e hlile ha e amehe ke metsoako ea tlhaho le oli. Matla a metsi a aramid a batla a lekana le matla a omileng. Ho tsitsisa ha mouoane oa metsi a tletseng metsi ho molemo ho feta ha likhoele tse ling tsa tlhaho.
Aramid e batla e utloa mabone a UV. Haeba e pepesehetse letsatsi ka nako e telele, e lahleheloa ke matla a mangata 'me ka hona e lokela ho sireletsoa ka lera le sireletsang. Lera lena le sireletsang le tlameha ho thibela tšenyo ea skeleton ea aramid leboneng la UV.
4. Ho hanyetsa mahlaseli
Ho hanyetsa mahlaseli ha li-aramids tsa interposition li ntle haholo. Ka mohlala, tlas'a 1.72x108rad / s ea r-radiation, matla a lula a le teng.
5. Ho tšoarella
Kamora ho hlatsuoa ha 100, matla a tabohileng a masela a m-aramid a ntse a ka fihla ho feta 85% ea matla a ona a mantlha. Thempereichara ea li-para-aramide e phahame ho feta ea li-inter-aramide, ka mocheso o tsoelang pele oa tšebeliso ea -196 ° C ho ea ho 204 ° C 'me ha ho na ho bola kapa ho qhibiliha ho 560 ° C. Tšobotsi ea bohlokoa ka ho fetisisa ea para-aramid ke matla a eona a phahameng le modulus e phahameng, matla a eona a feta 25g / dan, e leng makhetlo a 5 ~ 6 a tšepe ea boleng bo phahameng, linako tse 3 tsa fiber ea khalase le linako tse 2 tsa khoele ea indasteri ea nylon e matla. ; modulus ea eona ke makhetlo a 2 ~ 3 a tšepe ea boleng bo phahameng kapa fiber ea khalase le linako tse 10 tsa khoele ea indasteri ea nylon e matla haholo. Sebopeho se ikhethileng sa bokaholimo ba makhasi a aramid, se fumanoang ka fibrillation ea bokaholimo ba likhoele tsa aramid, se ntlafatsa haholo ho ts'oara ha motsoako 'me ka hona se loketse joalo ka faeba e matlafatsang bakeng sa lihlahisoa tsa likhohlano le ho tiisa. Aramid Pulp Hexagonal Special Fiber I Aramid 1414 Pulp, e mosehla o mosehla o mosehla, o boreleli, o nang le mapolanka a mangata, matla a phahameng, botsitso bo botle ba sebopeho, se sa qhekellang, se hanyetsanang le mocheso o phahameng, se hanyetsanang le kutu, se thata, se nyenyefalang se tlase, se hanyetsanang hantle le abrasion, sebaka se seholo sa bokaholimo. , tlamahano e ntle le lisebelisoa tse ling, thepa e matlafatsang e nang le ho khutla ha mongobo oa 8%, bolelele ba bolelele ba 2-2.5mm le sebaka se ka holimo sa 8m2 / g. E sebelisoa e le thepa e matlafatsang ea gasket e nang le botsitso bo botle le ts'ebetso ea ho tiisa, 'me ha e kotsi ho bophelo bo botle ba batho le tikoloho,' me e ka sebelisoa bakeng sa ho tiisa ka metsing, oli, e makatsang le e bohareng ea matla a acid le mecha ea alkali. Ho 'nile ha pakoa hore matla a sehlahisoa a lekana le 50-60% ea lihlahisoa tse matlafalitsoeng tsa fiber ea asbestos ha ho kenngoa ka tlase ho 10% ea slurry. E sebelisetsoa ho matlafatsa likhohlano le lisebelisoa tsa ho tiisa le lihlahisoa tse ling tse entsoeng, 'me e ka sebelisoa e le mokhoa o mong oa asbestos bakeng sa thepa ea ho tiisa ho ferekanngoa, pampiri e thibelang mocheso e phahameng le lisebelisoa tse matlafalitsoeng tse kopantsoeng.
