Girazi rinoshandiswa kugadzira girazi fiber rakasiyana nerezvimwe zvigadzirwa zvegirazi. Girazi rinoshandiswa kune fiber dzakatengeswa munyika rinosanganisira silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, nezvimwewo zvichienderana nealkali iri mugirazi, inogona kukamurwa kuita alkali isina girazi fiber. (sodium oxide 0% ~ 2%, yealuminium borosilicate girazi) uye yepakati alkali girazi fiber (sodium oxide 8% ~ 12%), ndeye sodium calcium silicate. girazi rine kana risina boron) uye yakakwirira alkali girazi fiber (inopfuura 13% sodium oxide ndeye sodium calcium silicate girazi).
1. E-girazi, iro rinozivikanwawo sealkali isina girazi, ibhorosilicate girazi. Iyo inonyanya kushandiswa girazi chikamu chegirazi fiber ine yakanaka magetsi ekudzivirira uye ma mechanical properties. Inoshandiswa zvakanyanya mukugadzirwa kwegirazi fiber yekuvharisa magetsi uye girazi fiber yeFRP. Kukanganisa kwayo ndeyekuti zviri nyore kunyungudutswa neinorganic acid, saka haina kukodzera kune acid nharaunda.
2. C-girazi, inozivikanwawo sepakati alkali girazi, inoratidzirwa nani makemikari kuramba, kunyanya asidhi kuramba, pane asiri alkali girazi, asi urombo magetsi kushanda uye 10% ~ 20% yakaderera mechanical simba pane asiri alkali girazi faibha. Kazhinji, yekunze yepakati alkali girazi fiber ine imwe huwandu hweboron trioxide, nepo China yepakati alkali girazi fiber haina boron zvachose. Munyika dzekunze, yepakati alkali girazi faibha inongo shandiswa kugadzira girazi risingadziviriri girazi fiber zvigadzirwa, senge girazi faibha pamusoro inonzwa, uye zvakare inoshandiswa kusimbisa asphalt denga zvinhu. Nekudaro, muChina, yepakati alkali girazi fiber account inopfuura hafu (60%) yekubuda kwegirazi fiber uye inoshandiswa zvakanyanya mukusimbisa FRP uye kugadzirwa kwesefa jira uye inosunga jira, Nekuti mutengo wayo wakaderera pane iwo. yealkali yemahara girazi fiber, ine kukwikwidza kwakasimba.
3. High simba girazi fiber inoratidzirwa nesimba guru uye yakakwirira modulus. Simba rayo rimwechete rinoita 2800mpa, iyo inenge 25% yakakwirira kudarika iyo alkali isina girazi fiber, uye elastic modulus yayo i86000mpa, iyo yakakwirira kudarika yeE-glass fiber. Zvigadzirwa zveFRP zvinogadzirwa navo zvinonyanya kushandiswa muindasitiri yemauto, nzvimbo, bulletproof nhumbi dzokurwa uye zvemitambo. Nekudaro, nekuda kwemutengo wakakwira, haigone kuve yakakurumbira mukushandiswa kwehurumende, uye kuburitswa kwenyika kunosvika zviuru zvematani.
4. Ar glass fiber, inozivikanwawo sealkali resistant glass fiber, inonyanya kugadzirwa kusimbisa simende.
5. Girazi, iro rinozivikanwawo segirazi repamusoro re alkali, girasi rinowanzoita sodium silicate. Haiwanzo shandiswa kugadzira girazi fiber nekuda kwekushomeka kwayo kwemvura.
6. E-CR girasi ibhoroni yakagadziridzwa isina uye alkali isina girazi, iyo inoshandiswa kugadzira girasi fiber ine acid yakanaka uye kudzivirira mvura. Kuramba kwayo kwemvura kuri nani 7 ~ 8 nguva pane iyo alkali isina girazi faibha, uye asidi yayo kuramba iri nani kupfuura yepakati alkali girazi fiber. Iri rudzi rutsva rwakanyanya kugadzirirwa mapaipi epasi pevhu uye matangi ekuchengetedza.
7. D girazi, inozivikanwawo segirazi yakaderera dielectric, inoshandiswa kubudisa dielectric glass fibers ine simba rakanaka re dielectric.
Pamusoro peiyo iri pamusoro pegirazi fiber zvikamu, nyowani alkali yemahara girazi fiber yakabuda mumakore achangopfuura. Iyo haina boron zvachose, kuitira kuti ideredze kusvibiswa kwezvakatipoteredza, asi ayo emagetsi ekudzivirira uye ma mechanical properties akafanana neaya echinyakare E girazi. Mukuwedzera, kune rudzi rwegirazi fiber ine zvikamu zviviri zvegirazi, iyo yakashandiswa mukugadzirwa kwegirazi mvere. Zvinonzi zvakare ine mukana seFRP kusimbisa. Pamusoro pezvo, kune fluorine-isina girazi faibha, inova yakagadziridzwa alkali isina girazi faibha yakagadziridzwa kuitira kuchengetedza kwezvakatipoteredza zvinodiwa.
