Pepa reAramid rinowanzo gadzirwa nekusanganisa ma aramid precipitated fibers uye aramid mapfupi mafiibhi e sheeting.

Kunyanya, semuenzaniso, nzira dzinotevera dzinogona kushandiswa: mushure mekuoma kusanganiswa kweiyo yambotaurwa aramid precipitated fibers uye aramid mapfupi fiber, iyo aramid precipitated fibers uye aramid mapfupi fiber anoparadzirwa uye anosanganiswa mukati memvura ichishandisa nzira yekuyerera kwemhepo, uyezve. inobuditswa pamvura inopindika inotsigira muviri (senge mesh kana bhandi) kugadzira pepa, uye nzira yekubvisa mvura nekuomesa inosarudzwa. Iyo inonzi yakanyorova yekugadzira nzira, iyo inoshandisa mvura sepakati, inosarudzwa.

Iyo nzira yekugadzira yearamid bepa

Iyo yekuumba kugadzirwa kwearamid fibers:

Polymerization: Muchikamu chekutanga, aramid fibers anorukwa kuita gobvu, akatsetseka-grained polima hupfu. Ichi chinyorwa chine chikuru chekushisa uye chemakemikari zvimiro zvepara aramid fibers. Nekudaro, haina izvo zvinosimbisa zvimiro zveshinda kana pulp. Iyi poda yakatsetseka inogona kushandiswa kuwedzera zvimiro zvezvikamu zvepurasitiki.

Kuruka: Muchikamu chechipiri chearamid fibers, iyo polima inonyungudutswa mu sulfuric acid kuti igadzire mvura yekristaro mhinduro. Zvadaro, mhinduro yacho yakarukwa kuita filaments yakanaka, imwe neimwe ine dhayamita ye 12 μ M. Chimiro chesiriki i100% subcrystalline, ine cheni dzema molecular dzakafanana nefiber axis. Iyi yakakwirira tsika kugovera inopa Twaron filament akasiyana akanakisa maitiro.

Short fiber: Artificial short fiber kana short cut fiber, iyo inogadziriswa nekukwenya shinda uye yozobatwa neagent yekupedzisa. Wapedza kuomeswa, cheka mafiibha acho kuita hurefu hwakanangwa wobva waaisa.

Kupinikidza mu pulp: Kuti ubudise pulp, aramid fibers anotanga acheka shinda uye ozoimisa mumvura kuti arapwe fibrosis. Ipapo inoiswa pasuru yakananga uye inotengeswa seyakanyorova pulp, kana kupera mvura uye kuomeswa seyakaoma pulp inotengeswa.
