Magirazi egirazi anoshanda zvakanyanyaYakagadzirwa nenzira inoshanda pamwe chete nezvikamu zvegirazi uye maitiro, zvichizopedzisira zvichiratidza mabhenefiti makuru pamusoro pemafiber egirazi echinyakare muzviratidzo zvakakosha zvakaita sesimba remakanika, elastic modulus, resistance tembiricha, resistance corrosion yemakemikari, uye dielectric properties. Nekuwedzera kwekuda kwekushanda kwezvinhu mumabasa epamusoro akadai sesimba remhepo, aerospace, uye electronic communications, mafiber egirazi anoshanda zvakanyanya ave chinhu chakakosha muindasitiri dziri kubuda.
1. Girazi Fiber Yakasimba Kwazvo
Girazi reS rinozivikanwa nesimba raro repamusoro, modulus, uye kuramba kwaro kurova. Pfupiso yemhando huru dzefaibha yegirazi inoshanda zvakanyanya
| Zita | Zvinhu Zvikuru | Zvakanakira Zvikuru | Minda Yekushandisa Yakajairika |
| Fiber yegirazi yakasimba kwazvo (Girazi reS) | Simba guru rekusimba uye kuramba tembiricha | Simba rakasimba, kuramba kuneta kwakanyanya | Zvimiro zvemuchadenga, midziyo yekudzivirira, midziyo yemitambo inoshanda zvakanyanya |
| Fiber yegirazi ine simba guru ine modulus (R-girazi) | Simba guru, modulus yakakwira, kuramba kuneta kwakanyanya | Kuomarara kwakanyanya, kushanduka kudiki, kushanda kwakaringana | Zvikamu zvemudenga, zvikamu zvemaindasitiri zvepamusoro-soro, midziyo yemitambo |
| Faibha yegirazi ine modulus yakakwirira (HME-girazi) | Modulus yakakwira zvakanyanya | Kuomarara kwakanaka, kwakakodzera zvivakwa zvinoda kuomarara kwakanyanya | Mapaipi emhepo anofambisa mhepo, mapaipi ane simba guru, zvikamu zvemuchadenga |
| Faibha yegirazi ine dielectric shoma (D-girazi) | Kurasikirwa kwakanyanya kwe dielectric constant uye dielectric | Kurasikirwa kwekutumira chiratidzo che high-frequency yakaderera, kumhanya kwekutumira nekukurumidza | Mabhodhi edunhu e5G/6G, ma radomes, kurongedza machipisi, zvivakwa zvinotumira mafungu |
| Fiber yegirazi isina Boron, isina fluorine, uye isina alkali (Advantex®) | Kuramba kwakanaka kweasidhi, kuumbwa kwakanaka kwezvakatipoteredza | Kushanda kwacho kwakafanana negirazi reE, kusina boron uye fluorine kusvibiswa | Nzvimbo dzekuchengetedza zvakatipoteredza, makemikari anodzivirira ngura, kutakurwa, kuputira magetsi |
| Faibha yegirazi isingapindi alkali (Girazi reAR) | Haipindi ngura munzvimbo dzine simende yealkaline | Inoshandiswa zvakanyanya pazvinhu zvakagadzirwa nesimende, inogara kwenguva refu | Zvigadzirwa zveGRC, mafacade ekuvaka, zvikamu zvakagadzirwa kare, masisitimu epasi |
Simba rayo rekudhonza rakakwirira ne30%–40% kupfuura reE-glass, elastic modulus yayo yakakwira ne16%–20%, uye kupisa kwayo kunovandudzwa ne100–150°C. Hunhu uhu hunoita kuti ive chinhu chinodiwa kune zvikamu zvinoshanda zvakanyanya zvakaita semuchadenga nemidziyo yekudzivirira. Mumakore achangopfuura, kuunzwa kwemachubhu ecarbon nano sechikamu chekusimbisa kwakasimbisa kusimba kwepakati pelaminar uye kuramba kuchenesa kweS-glass/epoxy laminates, zvichipa sarudzo itsva dzekushandisa muindasitiri yendege nemotokari.
2. Faibha yegirazi yakasimba kwazvo, ine modulus yakawanda
Girazi reR rinowana kuenzana kwakanaka kwesimba, modulus, uye kudzivirira kupisa, zvichiita kuti rive faibha inosimbisa inofarirwa kune zvigadzirwa zvakawanda zvine simba repamusoro. Kufanana negirazi reS, girazi reR rinoratidza kudzivirira kuneta kwakanyanya; zvinhu zvinosanganiswa zvinosimbiswa negirazi reR zvinoratidza kushanda kwekuneta zvakapetwa kagumi pane izvo zvinosimbiswa negirazi reE. Kusanganiswa uku kwehunhu kunoita kuti girazi reR rinyatsokodzera kushandiswa kwezvimiro zvinoda hunhu hwakareruka, kuomarara kwakanyanya, uye kugara kwenguva refu, zvakaita sezvikamu zvezvimiro zvemuchadenga, zvikamu zvemaindasitiri zvepamusoro, uye zvishandiso zvemitambo.
3. Faibha yegirazi ine modulus yakakwirira
Girazi reHME rinowana kuwedzera kukuru mu elastic modulus kuburikidza nekugadzira zvinhu zvitsva uye kugadzirisa mashandiro. Semuenzaniso, fiber yegirazi yekutanga yeM2 high-modulus (yakavakirwa paSiO2-Al2O3-MgO system, ine zvimwe zvakaita seCeO2, La2O3, uye ZrO2 yekusimudzira modulus) yakasvika pa elastic modulus ye93 GPa - inenge 30% yakakwira kupfuura yeE-glass. Fiber dzakadaro zvinhu zvakakosha pakushandiswa zvinosanganisira mashizha makuru e wind turbine uye midziyo yekumanikidza inodzivirira ngura. Pakati pemaitiro ekuenda kuma blades makuru e wind turbine, HME-glass rave chinhu chakakosha pakugadzira ma spars makuru ema blades anopfuura mamita zana pakureba. "Ultra-high modulus wind power yarn" yakagadzirwa nemabhizinesi emuno yatanga kushandiswa zvakanyanya; mushure mekupedza miedzo yekuneta inodarika mamiriyoni 1.5, inoramba ichisangana nezvinodiwa zvakasimba zvekuvimbika kwezvinhu zve blades dze wind turbine. Ongororo yemusika inoratidza kuti musika wepasi rose wefiber yegirazi ine modulus inoshandiswa mufiber-reinforced thermoplastics (FRTP) unotarisirwa kukura nechikamu chekuwedzera kwegore negore (CAGR) che5.3%, kusvika pakukura kwemusika kweUS$1.231 bhiriyoni panosvika gore ra2031, zvichiratidza kudiwa kwakasimba muzvikamu zvakaita semagetsi emhepo uye kupenya kwemotokari.
4. Faibha yegirazi isina dielectric yakawanda
Girazi reD-girazi rine dielectric yakaderera uye ine dielectric shoma, zvichiita kuti rive chinhu chakakodzera kushandiswa kwemagetsi ane mafrequency akawanda. Kudiwa kwemusika kuri kuramba kuchikwira pamwe chete nekugadzirwa kwetekinoroji ye5G/6G, AI computing, uye satellite communication. Makambani makuru emuno ari kusimudzira zvakanyanya kugadzirwa kwezvinhu izvi uye tekinoroji. Semuenzaniso, yarns dzegirazi dzemhando yepamusoro dze dielectric (LDK 2nd generation) nemachira zvinosangana nezvinodiwa zve laminates dzemhando yepamusoro, dzinomhanya zvakanyanya, uye dzinoshandiswa mu6G communications, AI servers, uye low-Earth orbit (LEO) satellites. Nezvekutsigira mutemo, madhipatimendi matanhatu ehurumende—kusanganisira Ministry of Industry and Information Technology—akapa zano rakajeka mu "Work Plan for Stable Growth in the Building Materials Industry (2025–2026)" kuti kushandiswa kwezvigadzirwa zvegirazi zve dielectric zvishoma kusimudzirwe muzvikamu zvakaita se next-generation displays uye integrated circuits. Izvi zvinopa gwara rakajeka rekusimudzira indasitiri uye zvinowedzera kugona kwayo mumusika.
5. Fiber yegirazi isina Boron, isina fluorine, uye isina alkali
Kunyange zvazvo ichichengetedza hunhu hwakakosha hwegirazi reE-glass, Advantex® inowedzera zvakanyanya kudzivirira ngura uye mabhenefiti ezvakatipoteredza nekubvisa zvinhu zvinokuvadza zvakaita seboron nefluorine. Izvi zvinoita kuti ive yakakodzera munzvimbo dzakaoma dzemaindasitiri uye mashandisirwo anotarisa kuchengetedzeka, kusanganisira nzvimbo dzekuchengetedza nharaunda (dzakadai semasisitimu ekubvisa flue gas desulfurization), mapaipi anodzivirira ngura eindasitiri yemakemikari, uye chikamu chekutakura.
6. Faibha yegirazi inodzivirira alkali
Kuburikidza nekugadzirwa kwakasarudzika kwemusanganiswa, AR-glass inokwanisa kutsungirira nharaunda yesimende ine alkaline yakawanda. Inoshanda sechinhu chakakosha chinosimbisa chinogonesa zvinhu zvakareruka, zvakasimba, uye zvakaoma zvakagadzirwa nesimende, zvakaita sekongiri yakasimbiswa nefiber yegirazi. Fiber idzi dzakagadzirirwa kugadzira mapaneru emadziro akareruka, machira ekunze, uye zvinhu zvakagadzirwa kare; dzinokwanisa kutsungirira nharaunda ine alkaline yakawanda inogadzirwa nezvinhu zvinogadzirwa nesimende uye dzinochengetedza kugara kwenguva refu, nokudaro dzichisimudzira tekinoroji yemazuva ano yekuvaka.
Kuburikidza nekugadzira magadzirirwo akanangana uye kugadzirisa maitiro, magirazi ane simba repamusoro anosangana nezvinodiwa zvakasimba zvekushanda kwezvinhu zvemhando yepamusoro. Sezvo tekinoroji ichifambira mberi uye nzvimbo dzekushandisa dzichiwedzera, magirazi ane simba repamusoro achaita basa rakakosha mukusimudzira kuvandudzwa kwemaindasitiri nekusimudzira nharaunda. Mafambiro emangwana anosanganisira: kuwedzera kwemashizha emhepo anofambisa mhepo zvichikonzera kudiwa kwemagirazi ane modulus; matekinoroji ekutaurirana e5G/6G anokurudzira hunyanzvi mumagirazi ane dielectric shoma; mitemo yezvakatipoteredza inosimudzira kuvandudzwa kwemagirazi ane hushamwari nezvakatipoteredza (semuenzaniso, asina boron uye asina fluorine); uye kugadzira kwakangwara kunorerutsa kugadzirwa kwemagadzirirwo. Sechikamu chakakosha chechikamu chezvinhu zvitsva, magirazi ane simba repamusoro ari kutungamira indasitiri yecomposites kuita basa repamusoro uye kugara kwenguva refu kwezvakatipoteredza, zvichipa rutsigiro rwezvinhu zvakakosha pakufambira mberi mune tekinoroji yemazuva ano yeindasitiri.
