I-fiber yengilazi inezakhiwo ezinhle kakhulu futhi isetshenziswa kabanzi emikhakheni eminingi. Iyinto engeyona eyensimbi engaphili engathatha indawo yensimbi. Ngenxa yamathemba ayo amahle okuthuthukiswa, izinkampani ezinkulu ze-fiber yengilazi zigxile ocwaningweni lokusebenza okuphezulu kanye nokwenza ngcono inqubo ye-fiber yengilazi.

I-mesh ye-fiberglass

1 Incazelo yefayibha yengilazi
I-fiber yengilazi uhlobo lwezinto ezingezona ezensimbi ezingaphili ezingangena esikhundleni sensimbi futhi zisebenza kahle kakhulu. Zilungiswa ngokudonsa ingilazi encibilikisiwe ibe yi-fiber ngesenzo samandla angaphandle. Zinezici zamandla aphezulu, i-modulus ephezulu kanye nokwelulwa okuphansi. Ukumelana nokushisa kanye nokucindezelwa, i-coefficient enkulu yokwandisa ukushisa, iphuzu lokuncibilika eliphezulu, izinga lokushisa layo lokuthambisa lingafinyelela ku-550 ~ 750 ℃, ukuzinza okuhle kwamakhemikhali, akulula ukukushisa, zinezici ezithile ezinhle kakhulu njengokumelana nokugqwala, futhi zisetshenziswe kabanzi emikhakheni eminingi.
 
2 Izici zefayibha yengilazi
Iphuzu lokuncibilika kwefayibha yengilazi lingu-680℃, iphuzu lokubila lingu-1000℃, kanti ubuningi bungu-2.4 ~ 2.7g/cm3. Amandla okuthamba angu-6.3 kuya ku-6.9 g/d esimweni esijwayelekile kanye no-5.4 kuya ku-5.8 g/d esimweni esimanzi.I-fiber yengilazi inokumelana okuhle nokushisa futhi iyinto yokuvikela esezingeni eliphezulu enokuvikela okuhle, efanelekile ekukhiqizweni kokuvikela ukushisa nezinto ezingashi.
 
3 Ukwakheka kwefayibha yengilazi
Ingilazi esetshenziswa ekukhiqizweni kwemicu yengilazi ihlukile kunengilazi esetshenziswa kweminye imikhiqizo yengilazi. Ingilazi esetshenziswa ekukhiqizweni kwemicu yengilazi iqukethe lezi zinto ezilandelayo:
(1)Ingilazi ye-E,eyaziwa nangokuthi ingilazi engena-alkali, ingeyasengilazini ye-borosilicate. Phakathi kwezinto ezisetshenziswa njengamanje ekukhiqizweni kwemicu yengilazi, ingilazi engena-alkali iyona esetshenziswa kakhulu. Ingilazi engena-alkali inokushisa okuhle kanye nezakhiwo zemishini, futhi isetshenziswa kakhulu ukukhiqiza imicu yengilazi evikela ukushisa kanye nemicu yengilazi enamandla aphezulu, kodwa ingilazi engena-alkali ayimelani nokugqwala kwe-inorganic acid, ngakho-ke ayifanele ukusetshenziswa ezindaweni ezine-acid. Sine-e-glassukuzulazula kwe-fiberglass, ingilazi ye-eukuzulazula okulukiwe kwe-fiberglass，kanye ne-e-glassumbhede we-fibegrlass.
 
(2)Ingilazi engu-C, eyaziwa nangokuthi ingilazi ephakathi ne-alkali. Uma iqhathaniswa nengilazi engena-alkali, inokumelana okungcono kwamakhemikhali kanye nezakhiwo zikagesi nezemishini ezimbi. Ukwengeza i-diboron trichloride engilazini ephakathi ne-alkali kungakhiqizaumbhede wobuso befayibha yengilazi,enezici zokumelana nokugqwala. Imicu yengilazi ye-alkali ephakathi engenayo i-boron isetshenziswa kakhulu ekukhiqizweni kwezindwangu zokuhlunga kanye nezindwangu zokugoqa.

(3)I-fiber yengilazi enamandla aphezulu,njengoba igama lisho, i-fiber yengilazi enamandla aphezulu inezici zamandla aphezulu kanye ne-modulus ephezulu. Amandla ayo okudonsa i-fiber angama-2800MPa, aphakeme cishe ngo-25% kune-fiber yengilazi engena-alkali, kanti i-modulus yayo enwebekayo ingu-86000MPa, ephakeme kune-fiber yengilazi ye-E. Umphumela we-fiber yengilazi enamandla aphezulu awuphezulu, uhambisana namandla ayo aphezulu kanye ne-modulus ephezulu, ngakho-ke ivame ukusetshenziswa kwezempi, ezindizayo kanye nemishini yezemidlalo kanye neminye imikhakha, futhi ayisetshenziswa kabanzi kweminye imikhakha.
 
(4)I-AR glass fiber, eyaziwa nangokuthi i-fiber yengilazi engamelani ne-alkali, iyi-fiber engaphili. I-fiber yengilazi engamelani ne-alkali inokumelana okuhle kwe-alkali futhi ingamelana nokugqwala kwezinto eziphezulu ze-alkali. Ine-modulus ephezulu kakhulu yokunwebeka kanye nokumelana nomthelela, amandla okuthamba kanye namandla okugoba. Iphinde ibe nezici zokungashi, ukumelana nesithwathwa, ukumelana nokushisa kanye nomswakama, ukumelana nokuqhekeka, ukungenwa kwamanzi, i-plasticity eqinile kanye nokubumba okulula. Izinto zembambo zekhonkrithi eqinisiwe ye-fiber yengilazi.
 
4 Ukulungiswa kwemicu yengilazi
Inqubo yokukhiqizai-fiber yengilazingokuvamile kufanele kuqala kuncibilikiswe izinto zokusetshenziswa, bese kwenziwa ukwelashwa nge-fiberizing. Uma kuzokwenziwa ngesimo samabhola e-fiber engilazi noma izinduku ze-fiberglass, ukwelashwa nge-fiberizing akukwazi ukwenziwa ngqo. Kunezinqubo ezintathu ze-fibrillation ze-fiber engilazi:
Indlela yokudweba: indlela eyinhloko yindlela yokudweba nge-filament nozzle, elandelwa indlela yokudweba ngenduku yengilazi kanye nendlela yokudweba nge-melt drop;
Indlela ye-Centrifugal: i-drum centrifugation, i-step centrifugation kanye ne-horizontal porcelain disc centrifugation;
Indlela yokufutha: indlela yokufutha kanye nendlela yokufutha i-nozzle.
Izinqubo eziningana ezingenhla zingasetshenziswa futhi ngokuhlanganiswa, njengokudonsa nokushaya njalo njalo. Ukucubungula ngemuva kwenzeka ngemva kokufaka i-fiber. Ukucubungula ngemuva kokufaka i-fiber kuhlukaniswe ngezinyathelo ezimbili ezinkulu ezilandelayo:
(1) Ngesikhathi kukhiqizwa imicu yengilazi, imicu yengilazi ehlanganiswe ngaphambi kokugoqa kufanele ibe nosayizi, kanti imicu emifushane kufanele ifuthwe nge-lubricant ngaphambi kokuba iqoqwe futhi ifakwe izimbobo.
(2) Ukucutshungulwa okuqhubekayo, ngokuya ngesimo sefayibha yengilazi emfushane kanye nefibre emfushaneukuhambahamba ngefayibha yengilazi kunezinyathelo ezilandelayo:
①Izinyathelo zokucubungula ifayibha yengilazi emfushane:
②Izinyathelo zokucubungula ingilazi eyisisekelo yokuzulazula:
