Cov iav fiber ntau (lub npe qub ua lus Askiv: iav fiber ntau lossis cov fiberglass) yog cov khoom siv tsis zoo nkauj uas tsis yog xim hlau nrog kev ua tau zoo heev. Nws muaj ntau yam ntawm cov txiaj ntsig zoo. Qhov zoo yog cov rwb thaiv tsev zoo, muaj zog kub tiv thaiv, zoo corrosion tsis kam, thiab muaj qhov tsis zoo yog rab phom, hnav tsis zoo. Cov iav fiber ntau feem ntau yog siv los ua cov khoom siv uas txhawb nqa hauv cov khoom siv sib xyaw, cov hluav taws xob rwb thaiv tsev thiab lwm daim teb thiab lwm qhov chaw ntawm kev lag luam hauv tebchaws.

Dab tsi yog lub hom phiaj tseem ceeb ntawm fiberglass roving?
Cov xov tooj iav fiber ntau yog tsuas yog siv los ua hluav taws xob cov khoom siv lim, tshuaj tiv thaiv lub suab, thiab tseem tuaj yeem siv ua cov khoom siv ntxiv. Kev siv cov xov tooj iav fiber ntau dua li lwm hom fibers kom txhawb cov khoom siv lub zog, iav xovtooj lossis txhawb cov roj hmab, siv cov khoom siv thiab lwm yam khoom. Cov xov tooj iav fiber ntau yog coated cov organic khoom los txhim kho nws cov ntaub pua chaw, siv cov ntaub npog, npog phab ntsa, thiab cov khaub ncaws tiv thaiv. Thiab rwb thaiv tsev thiab lub suab rwb thaiv tsev cov ntaub ntawv.

Yuav ua li cas thiaj paub qhov txawv ntawm cov fiberglass roving?  
Iav Fiber yog ua los ntawm cov iav ua cov khoom siv raw thiab ua tiav los ntawm ntau txoj kev moulding hauv lub xeev molten. Feem ntau muab faib ua cov iav fiber ntau thiab cov iav ua haujlwm tsis zoo. Ntawm kev ua lag luam, ntau nruam cov iav fiberers yog siv. Muaj ob qho khoom lag luam tseem ceeb ntawm cov iav txuas ntxiv. Ib qho yog nruab nrab-alkali iav fiber ntau, code-muaj npe c; Lwm tus yog cov iav dawb fiber ntau, code-muaj npe E. Qhov sib txawv tseem ceeb ntawm lawv yog cov ntsiab lus ntawm alkali hlau oxides. Nruab Nrab-Alkali iav fiber yog (12 ± 0.5)%, thiab cov iav dawb alkali yog <0.5%. Kuj tseem muaj qhov tsis yog tus qauv iav fiber ntau cov khoom lag luam ntawm kev ua lag luam. Feem ntau paub cov iav siab alkali iav fiber ntau. Cov ntsiab lus ntawm alkali hlau oxides yog siab dua 14%. Cov khoom siv raw rau ntau lawm yog iav lossis iav fwj. Cov iav fiber no muaj cov dej tsis zoo, muaj zog dua tshuab zog thiab cov rwb thaiv hluav taws xob, uas tsis raug tsim tawm los ntawm cov kev cai hauv tebchaws.

Feem ntau tsim nyog nruab nrab-alkali thiab alkali-dawb iav xov tooj cov xov paj, thiab txhua tus lej bibned nrog tus lej, thiab cov qhab nia tshuaj xyuas cov ntaub ntawv pov thawj yuav tsum tau nqa tawm hauv lub thawv. Cov ntsiab lus ntawm cov khoom tshuaj xyuas thiab kev txheeb xyuas suav nrog:
1. Lub npe ntawm cov chaw tsim tshuaj paus;
2. Qhov chaws thiab qib ntawm cov khoom lag luam;
3. Tus naj npawb ntawm cov qauv no;
4. Stamp nrog lub foob tshwj xeeb rau kev tshuaj xyuas zoo;
5. NET qhov hnyav;
6. Lub thawv ntim khoom yuav tsum muaj lub npe Hoobkas, cov qauv khoom lag luam thiab qib, tus lej cim, hnub hnyav, thiab lwm hnub thiab lwm yam.
