Cov iav siv los tsim cov iav fiber ntau txawv ntawm lwm cov khoom iav. Cov iav siv rau cov fibers uas tau ua lag luam nyob hauv lub ntiaj teb no muaj silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, thiab lwm yam raws li cov ntsiab lus alkali hauv iav, nws tuaj yeem muab faib ua alkali dawb iav fiber ntau. (sodium oxide 0% ~ 2%, belongs rau aluminium borosilicate iav) thiab nruab nrab alkali iav fiber (sodium oxide 8% ~ 12%), Nws belongs rau sodium calcium silicate iav uas muaj lossis tsis muaj boron) thiab siab alkali iav fiber ntau (ntau tshaj 13% sodium oxide belongs rau sodium calcium silicate iav).

1. E-iav, tseem hu ua alkali dawb iav, yog borosilicate iav. Cov iav feem ntau siv rau iav fiber ntau muaj hluav taws xob zoo thiab cov khoom siv kho tshuab. Nws yog dav siv hauv kev tsim cov iav fiber ntau rau hluav taws xob rwb thaiv tsev thiab iav fiber ntau rau FRP. Nws qhov tsis zoo yog tias nws yooj yim rau eroded los ntawm inorganic acid, yog li nws tsis haum rau acid ib puag ncig.

2. C-iav, tseem hu ua nruab nrab alkali iav, yog tus cwj pwm los ntawm cov tshuaj tiv thaiv zoo dua, tshwj xeeb tshaj yog acid tsis kam, dua li cov iav tsis alkali, tab sis tsis zoo hluav taws xob kev ua tau zoo thiab 10% ~ 20% qis txhua yam muaj zog dua li cov iav fiber ntau. Feem ntau, txawv teb chaws nruab nrab alkali iav fiber ntau muaj ib tug npaum li cas ntawm boron trioxide, thaum Tuam Tshoj tus nruab nrab alkali iav fiber tsis muaj boron kiag li. Hauv cov teb chaws txawv teb chaws, nruab nrab alkali iav fiber ntau tsuas yog siv los tsim cov khoom siv hluav taws xob tiv thaiv iav fiber ntau, xws li iav fiber ntau qhov chaw, thiab tseem siv los ntxiv dag zog rau cov ntaub ntawv asphalt vov tsev. Txawm li cas los xij, nyob rau hauv Suav teb, nruab nrab alkali iav fiber ntau tso nyiaj rau ntau tshaj ib nrab (60%) ntawm cov khoom siv iav fiber ntau thiab yog dav siv nyob rau hauv lub zog ntawm FRP thiab zus tau tej cov lim ntaub thiab binding ntaub, vim hais tias nws cov nqi yog qis dua li. ntawm alkali dawb iav fiber ntau, nws muaj kev sib tw muaj zog.

3. Lub zog muaj zog iav fiber ntau yog tus yam ntxwv ntawm lub zog siab thiab siab modulus. Nws ib leeg fiber ntau tensile zog yog 2800mpa, uas yog hais txog 25% siab dua li ntawm alkali dawb iav fiber ntau, thiab nws elastic modulus yog 86000mpa, uas yog siab tshaj ntawm E-iav fiber. FRP cov khoom tsim los ntawm lawv feem ntau yog siv rau hauv kev lag luam tub rog, qhov chaw, cov cuab yeej tiv thaiv mos txwv thiab cov khoom ua si. Txawm li cas los xij, vim yog tus nqi siab, nws tsis tuaj yeem nrov hauv kev siv pej xeem, thiab cov khoom tsim tawm hauv ntiaj teb yog txog ntau txhiab tons.

4. Ar iav fiber, tseem hu ua alkali resistant iav fiber ntau, yog tsim los ntxiv dag zog rau cov cement.

5. Ib lub khob, tseem hu ua siab alkali iav, yog ib qho tshuaj sodium silicate iav. Nws tsis tshua muaj siv los tsim cov iav fiber ntau vim nws cov dej tsis zoo.

6. E-CR iav yog ib qho kev txhim kho boron dawb thiab alkali dawb iav, uas yog siv los tsim cov iav fiber ntau nrog cov kua qaub thiab dej tsis zoo. Nws cov dej tsis kam yog 7 ~ 8 npaug zoo dua li ntawm alkali dawb iav fiber ntau, thiab nws cov kua qaub kuj zoo dua li ntawm nruab nrab alkali iav fiber ntau. Nws yog ntau yam tshiab tshwj xeeb tsim rau cov kav dej hauv av thiab cov tso tsheb hlau luam.

7. D iav, tseem hu ua low dielectric iav, yog siv los tsim cov iav uas tsis muaj dielectric nrog zoo dielectric zog.

Ntxiv nrog rau cov iav fiber ntau saum toj no, ib qho tshiab alkali dawb iav fiber ntau tau tshwm sim nyob rau xyoo tas los no. Nws tsis muaj boron txhua, thiaj li yuav txo tau ib puag ncig muaj kuab paug, tab sis nws cov hluav taws xob rwb thaiv tsev thiab txhua yam khoom zoo ib yam li cov tsoos E iav. Tsis tas li ntawd, muaj ib hom iav fiber ntau nrog ob lub iav iav, uas tau siv los ua cov iav ntaub plaub. Nws tau hais tias nws kuj muaj peev xwm ua FRP kev txhawb zog. Tsis tas li ntawd, muaj fluorine-dawb iav fiber ntau, uas yog kev txhim kho alkali dawb iav fiber ntau tsim rau kev tiv thaiv ib puag ncig.
