Girazi faibha (yaimbozivikanwa muChirungu segirazi faibha kana fiberglass) inorganic isiri-metallic material ine mashandiro akanaka. Iine zvakasiyana-siyana. Zvakanakira kuvharidzira kwakanaka, kupisa kwakasimba kwekudzivirira, kunaka kwekusagadzikana uye kusimba kwemagetsi kwakakwira, asi zvisungo zvaro zvine brittle uye kusapfeka kusakara. Girazi faibha rinowanzo shandiswa sekusimbisa zvinhu mucomposites, magetsi ekudzivirira zvinhu uye thermal insulation material, circuit substrate uye mamwe minda yehupfumi hwenyika.
Muna 2021, huwandu hwekugadzira mabhora egirazi ekudhirowa kwewaya kweakasiyana crucibles muChina hwaive matani 992000, nekuwedzera kwegore negore kwe3.2%, iyo yainonoka zvakanyanya kupfuura yegore rapfuura. Pasi pemashure e "double kabhoni" nzira yekuvandudza, girazi bhora kiln mabhizinesi ari kutarisana nekuwedzera kuvharika kwekumanikidza maererano nekupihwa kwesimba uye mutengo wezvinhu.
Chii chinonzi fiberglass yarn?
Girazi faibha yarn imhando ye inorganic isiri-metallic zvinhu zvine mashandiro akanaka. Kune marudzi akawanda egirazi fiber warn. Zvakanakira zvegirazi fiber shinda yakanaka insulation, yakasimba kupisa kupisa, yakanaka corrosion resistance uye high mechanical simba, asi zvinoipira brittle uye kusapfeka zvakanaka kuramba. Girazi faibha shinda inogadzirwa negirazi bhora kana marara girazi kuburikidza nepamusoro-tembiricha kunyunguduka, kudhirowa waya, mhepo, kurukwa uye mamwe maitiro, Iyo dhayamita yemonofilament yayo akati wandei mamicrons kusvika kumamita makumi maviri, ayo akaenzana ne1 / 20-1 / 5 yebvudzi. Imwe neimwe bundle ye fiber precursor inoumbwa nemazana kana kunyange zviuru zve monofilaments.
Chii chinangwa chikuru chegirazi fiber warn?
Girazi faibha shinda inonyanya kushandiswa semagetsi ekudzivirira emagetsi, maindasitiri mafirita zvinhu, anti-corrosion, hunyoro-uchapupu, kupisa kupisa, kuvharidzira ruzha uye kunyura zvinhu, uye zvakare sezvinhu zvekusimbisa. Girazi faibha yarn inoshandiswa zvakanyanya kupfuura mamwe marudzi eshinda kugadzira mapurasitiki akasimbiswa, girazi faibha shinda kana yakasimbiswa rabha, yakasimbiswa gypsum uye yakasimbiswa simende, Girazi faibha shinda yakaputirwa nezvinhu zvehupenyu. Girazi fiber inogona kuvandudza kuchinjika kwayo uye inogona kushandiswa kugadzira jira rekurongedza, sikirini yehwindo, jira remadziro, jira rekuvhara, zvipfeko zvekudzivirira, magetsi ekudzivirira uye manzwi ekudzivirira.
Ndeapi maitiro egirazi fiber warn?
Twistless roving, twistless roving jira (checkered jira), girazi fiber yakanzwa, yakachekwa precursor uye pasi fiber, girazi fiber jira, yakasanganiswa girazi fiber reinforcement, girazi fiber yakanyorova yakanzwa.
Ko shinda yegirazi fiber ribhoni inorevei kana kazhinji shinda makumi matanhatu pa100cm?
Iyi ndiyo data yakatarwa yezvigadzirwa, zvinoreva kuti pane 60 yarn mu 100 cm.
Nzira yekukura sei girazi fiber yarn?
Kune girazi shinda yakagadzirwa negirazi faibha, shinda imwe chete inowanzoda saizi, uye filament kaviri tambo yeshinda haigone kuita saizi. Girazi machira efiber ari mudiki mabhechi. Naizvozvo, mazhinji acho ari kuyera neakaoma saizi kana slitting saizi muchina, uye vashoma vari kuyera ne shaft warp sizing muchina. Sizing ine starch size, starch semumiriri weboka, sekureba diki saizi reti (inenge 3%) inogona kushandiswa. Kana iwe ukashandisa shaft saizi muchina, unogona kushandisa imwe PVA kana acrylic saizi.
Ndeapi mazwi egirazi fiber warn?
Iyo acid inopikisa, magetsi kuramba uye mechanical zvimiro zvealkali isina girazi fiber zviri nani pane izvo zvepakati alkali.
"Bazi" chikamu chinoratidza kutsanangurwa kwegirazi fiber. Iyo inotsanangurwa zvakananga sehurefu hwe1G girazi fiber. 360 mapazi zvinoreva kuti 1g yegirazi fiber ine 360 metres.
Tsanangudzo uye modhi tsananguro, semuenzaniso: EC5 5-12x1x2S110 ndeye ply shinda.

Ndeupi musiyano uripo pakati pepakati alkali girazi faibha, isiri alkali girazi faibha uye yakakwirira alkali girazi faibha?
Nzira iri nyore yekusiyanisa yepakati alkali girazi faibha, isiri alkali girazi faibha uye yakakwira alkali girazi faibha ndeyekudhonza shinda imwe chete neruoko. Kazhinji, isiri alkali girazi faibha ine yakakwira mechanika simba uye haisi nyore kutyora, ichiteverwa nepakati alkali girazi faibha, nepo yakakwirira alkali girazi faibha inotsemuka kana ichidhonzwa zvinyoro nyoro. Zvinoenderana nekutarisa kweziso rakashama, iyo alkali yemahara uye yepakati alkali girazi faibha shinda kazhinji haina chiitiko cheshinda yemvere, nepo shinda yeshinda yemhando yepamusoro alkali girazi faibha yeshinda yakanyanya kukomba, uye akawanda akatyoka monofilaments anobaya matavi eshinda.
Nzira yekuziva sei kunaka kwegirazi fiber yarn?
Girazi faibha inogadzirwa negirazi nenzira dzakasiyana siyana dzekuumba mune yakanyungudutswa. Iyo inowanzo kupatsanurwa kuita inoenderera girazi fiber uye discontinuous girazi fiber. Kuenderera mberi girazi fiber inonyanya kufarirwa pamusika. Iko kune anonyanya marudzi maviri ekuenderera mberi kwegirazi fiber zvigadzirwa zvinogadzirwa zvinoenderana neazvino zviyero muChina. Imwe ndeyepakati alkali girazi fiber, kodhi inonzi C; Imwe ndeye alkali isina girazi fiber, kodeti inonzi E. Musiyano mukuru pakati pavo ndeyemukati wealkali metal oxides. (12 ± 0.5)% yepakati alkali girazi faibha uye <0.5% yeisina alkali girazi faibha. Iko kune zvakare isiri-yakajairwa chigadzirwa chegirazi fiber pamusika. Inowanzozivikanwa seyakakwira alkali girazi fiber. Izvo zviri mukati mealkali metal oxides zvinopfuura 14%. Izvo zvigadzirwa zvekugadzira zvakaputsika girazi regirazi kana mabhodhoro egirazi. Rudzi urwu rwegirazi faibha ine kusamira zvakanaka kwemvura, kusimba kwemagetsi uye kushomeka kwemagetsi. Hazvibvumirwi kugadzira zvigadzirwa maererano nemitemo yenyika.
Kazhinji akakodzera epakati alkali uye asiri alkali girazi faibha yeshinda zvigadzirwa zvinofanirwa kuve zvakasungwa ronda pashinda chubhu. Imwe neimwe chubhu yeshinda yakanyorwa nenhamba, strand nhamba uye giredhi, uye chigadzirwa chekuongorora chitupa chinopihwa mubhokisi rekurongedza. Chitupa chekuongorora chigadzirwa chinosanganisira:
1. Zita remugadziri;
2. Kodhi uye giredhi rezvigadzirwa;
3. Nhamba yechiyero ichi;
4. Dhinda chisimbiso chakakosha chekuongorora kwemhando;
5. Huremu hweNet;
6. Bhokisi rekutakura richava nezita refekitari, kodhi yechigadzirwa uye giredhi, nhamba yakajairika, uremu hwemambure, zuva rekugadzira uye nhamba yebatch, nezvimwe.
Nzira yekushandisazve girazi fiber tsvina silika uye shinda?
Mushure mekutyoka, marara girazi rinogona kushandiswa seyakabikwa yezvigadzirwa zvegirazi. Dambudziko rekunze kwezvinhu / wetting agent yasara inoda kugadziriswa. Tsvina yemarara inogona kushandiswa seyakajairwa girazi fiber zvigadzirwa, senge kunzwa, FRP, mataira, nezvimwe.
Nzira yekudzivirira sei zvirwere zvebasa mushure mekugara kwenguva refu negirazi fiber yarn?
Mashandiro ekugadzira anofanirwa kupfeka masiki ehunyanzvi, magurovhosi uye maoko kudzivirira zvakanangana neganda neshinda yegirazi fiber.
