Kurongwa kwegirazi fibers

Zvinoenderana nechimiro uye kureba, fiber yegirazi inogona kukamurwa kuita fiber inoenderera, yakatarwa urefu fiber uye girazi mvere; Zvinoenderana nekuumbwa kwegirazi, inogona kukamurwa kuita alkali isina, kemikari isingaite, yakakwira alkali, yepakati alkali, simba repamusoro, yakakwira elastic modulus uye alkali inodzivirira girazi fiber.

Girazi fiber yakakamurwa kuita mamakisi akasiyana zvichienderana nekuumbwa, hunhu uye kushandiswa. Zvinoenderana nechiyero, Giredhi E girazi fiber ndiyo inonyanya kushandiswa uye inoshandiswa zvakanyanya mumagetsi ekudzivirira zvinhu; Grade s is a special fiber. Kunyange zvazvo kubuda kuri kuduku, kunokosha zvikuru. Nekuti ine simba repamusoro, rinonyanya kushandiswa kudzivirira mauto, senge bulletproof bhokisi, nezvimwe; Giredhi C rinoshingirira makemikari kupfuura Giredhi E uye rinoshandiswa bhatiri rekuparadzanisa ndiro uye kemikari chepfu sefa; Kirasi A ndeye alkaline girazi fiber, iyo inoshandiswa kugadzira kusimbisa.

Kugadzirwa kwegirazi fiber

Zvinhu zvakakosha zvekugadzira girazi faibha ijecha requartz, alumina uye pyrophyllite, limestone, dolomite, boric acid, soda ash, mirabilite, fluorite, etc. Nzira dzekugadzira dzinogona kukamurwa kuita zvikamu zviviri: imwe ndeyekugadzira zvakananga girazi rakanyungudutswa kuti rive. fibers; Imwe ndeyekuita girazi rakanyungudutswa mubhora regirazi kana tsvimbo ine dhayamita ye20mm, uye wozopisa uye uigadzirise nenzira dzakasiyana-siyana kuti uigadzire nehupamhi hwe 3 ~ 80 μ Fiber yakanaka kwazvo yeM. Iyo isingagumi fiber inodhonzwa ne. mechanical kudhirowa kuburikidza neplatinum alloy plate inonzi inoenderera girazi fiber, iyo inowanzonzi refu fiber. Discontinuous fibers yakagadzirwa ne roller kana air flow inonzi fixed length glass fibers, inowanzonzi mapfupi. Mafiibhi akanaka, mapfupi uye akatsetseka akagadzirwa ne centrifugal force kana high-speed air flow anodaidzwa kuti glass wool. Mushure mekugadzirisa, girazi fiber inogona kugadzirwa kuita akasiyana marudzi ezvigadzirwa, senge shinda, twistless roving, yakachekwa precursor, jira, bhandi, kunzwa, ndiro, chubhu, nezvimwe.
