Fiber yegirazi (zita rekutanga muchiRungu: fiber yegirazi kana fiberglass) chinhu chisina kugadzirwa nesimbi chinoshanda zvakanaka. Chine zvakanakira zvakasiyana-siyana. Zvakanakira zvacho ipurasitiki yakanaka, inodzivirira kupisa zvakanyanya, inodzivirira ngura zvakanaka, uye ine simba rakawanda remuchina, asi chakaipa ndechekuti haishande zvakanaka, haiparare zvakanaka. Fiber yegirazi inowanzo shandiswa sechinhu chinosimbisa zvinhu zvakagadzirwa, zvinhu zvinodzivirira kupisa zvemagetsi nezvinhu zvinodzivirira kupisa, mabhodhi edunhu nedzimwe nzvimbo dzehupfumi hwenyika.
Chinangwa chikuru cheFiberglass Roving ndechei?
Shinda yegirazi inoshandiswa zvakanyanya sezvinhu zvinodzivirira kupisa, zvinhu zvinosefa zveindasitiri, zvinodzivirira ngura, zvinodzivirira hunyoro, zvinodzivirira kupisa, zvinodzivirira ruzha, zvinodzivirira kuvhunduka, uye zvinogona kushandiswawo sezvinhu zvinosimbisa. Kushandiswa kweshinda yegirazi kwakakura kupfuura mamwe marudzi emashinda kugadzira simbi yepurasitiki, shinda yegirazi kana rabha yakasimbiswa, plaster yakasimbiswa, simende yakasimbiswa nezvimwe zvigadzirwa. Shinda yegirazi yakafukidzwa nezvinhu zvakasikwa kuti ivandudze kuchinjika kwayo uye inoshandiswa kugadzira jira rekurongedza, kuvharira mahwindo, kufukidza madziro, jira rekufukidza, uye zvipfeko zvekudzivirira. Uye zvinhu zvinodzivirira kupisa uye zvinodzivirira ruzha.
Nzira yekusiyanisa sei mhando yeFiberglass Roving?
Fiber yegirazi inogadzirwa negirazi sechinhu chisina kugadzirwa uye inogadziriswa nenzira dzakasiyana-siyana dzekuumba dzakanyungudutswa. Kazhinji yakakamurwa kuita fiber yegirazi inoenderera mberi uye fiber yegirazi isingachinji. Pamusika, mafiriber egirazi anoenderera mberi anoshandiswa. Kune zvigadzirwa zviviri zvikuru zvefiber yegirazi inoenderera mberi. Imwe ifiriber yegirazi yepakati-alkali, inonzi C; imwe ifiriber yegirazi isina alkali, inonzi E. Musiyano mukuru pakati pavo ndewehuwandu hwealkali metal oxides. Fiber yegirazi yepakati-alkali ndeye (12±0.5)%, uye fiber yegirazi isina alkali iri <0.5%. Kunewo chigadzirwa chegirazi chisina kujairika chiri pamusika. Chinozivikanwa sefiber yegirazi ine alkali yakawanda. Hunhu hwealkali metal oxides huri pamusoro pe14%. Zvinhu zvekugadzira igirazi rakapwanyika kana mabhodhoro egirazi. Rudzi urwu rwefiriber yegirazi haruna simba remvura, simba remuchina rakaderera uye insulation yemagetsi yakaderera, izvo zvisingabvumirwe kugadzirwa nemitemo yenyika.
Zvigadzirwa zveshinda yegirazi yefaibha yepakati nepakati uye isina alkali zvinofanirwa kusungirirwa zvakasimba pabhobhini, uye bobhini yega yega yakanyorwa nhamba, nhamba yetambo uye giredhi, uye kuongororwa kwechigadzirwa kunofanirwa kuitwa mubhokisi rekurongedza. Zviri mukati mekuongorora nekusimbiswa kwechigadzirwa zvinosanganisira:
1. Zita remugadziri;
2. Kodhi uye giredhi rechigadzirwa;
3. Nhamba yechiyero ichi;
4. Chidhindo chine chisimbiso chakakosha chekuongorora mhando;
5. Huremu hwese;
6. Bhokisi rekurongedza rinofanira kunge riine zita refekitori, kodhi yechigadzirwa negiredhi, nhamba yakajairika, huremu hwese, zuva rekugadzirwa uye nhamba yebhechi, nezvimwewo.
