Umthelela We-Fiberglass Ekumelaneni Nokuguguleka Kokhonkolo Osenziwe Kabusha

Umthelela we-fiberglass ekumelaneni nokuguguleka kukakhonkolo osetshenziswe kabusha (owenziwe ngezinhlanganisela zikakhonkolo ogaywe kabusha) isihloko esithakaselwa kakhulu kwisayensi yezinto zokwakha kanye nobunjiniyela bomphakathi. Nakuba ukhonkolo ogaywe kabusha unikeza izinzuzo zemvelo kanye nezinsiza-kuphinda zigaywe, izici zayo zemishini nokuqina (isb., ukumelana nokuguguleka) kuvame ukuba ngaphansi kunokhonkolo ovamile. I-Fiberglass, njenge-aizinto eziqinisayo, ingathuthukisa ukusebenza kukakhonkolo ophinde wagaywa kabusha ngezinqubo ezibonakalayo namakhemikhali. Nakhu ukuhlaziya okuningiliziwe:

1. Izakhiwo kanye nemisebenzi yeI-Fiberglass

I-Fiberglass, i-inorganic non-metallic material, ibonisa izici ezilandelayo:
Amandla okuqina aphezulu: Anxephezela umthamo ophansi wokunyakaza kakhonkolo.
Ukumelana nokugqwala: Imelana nokuhlaselwa ngamakhemikhali (isb., ama-ion e-chloride, ama-sulfate).
Ukuqina nokumelana nokuqhekeka**: Ibhuloho ama-microcracks ukuze ibambezeleke ukusakazeka kwemifantu futhi inciphise ukungena.

2. Ukuqina Okushodayo Kokhonkolo Ogaywe Kabusha

Ama-aggregate agaywe kabusha anamathelisa usimende osalayo anezimbotshana endaweni yawo aholela kulokhu:
Indawo yenguquko enobuso obungaqinile (ITZ): Isibopho esingesihle phakathi kwezilinganiso ezigaywe kabusha nokunamathisela usimende okusha, okudala izindlela ezingenekayo.
Ukungangenisi okuphansi: Izinto ezigugulekayo (isb, i-Cl⁻, SO₄²⁻) zingena kalula, zibangele ukugqwala kwensimbi noma umonakalo omkhulu.
Ukumelana nokuncibilika okungalungile kweqhwa: Ukunwetshwa kweqhwa ezimbotsheni kubangela ukuqhekeka nokuqhekeka.

3. Izindlela ze-Fiberglass ekuthuthukiseni ukumelana nokuguguleka

(1) Imithelela Yezithiyo Emzimbeni
I-Crack inhibition: Imicu ehlakazekile ngokulinganayo ivala ama-microcracks, avimbe ukukhula kwawo futhi anciphise izindlela zama-erosive agents.
Ukubumbana okuthuthukisiwe: Imicu egcwalisa izimbotshana, yehlisa ukubola futhi ibambezela ukusakazeka kwezinto eziyingozi.

(2) Ukuzinza Kwamakhemikhali
I-fiberglass engazweli nge-alkali(isb, ingilazi ye-AR): Amafayibha afakwe phezulu ahlala azinzile endaweni ene-alkali ephezulu, egwema ukuwohloka.
Ukuqinisa isixhumi esibonakalayo: Isibopho esiqinile se-fiber-matrix kunciphisa ukukhubazeka ku-ITZ, kunciphisa izingozi zokuguguleka kwendawo.

(3) Ukumelana Nezinhlobo Ezithize Zokuguguleka
Ukumelana ne-Chloride ion: Ukuncipha kokwakheka kokuqhekeka kunciphisa u-Cl⁻ukungena, kubambezele ukugqwala kwensimbi.
Ukumelana nokuhlasela kwe-sulfate: Ukukhula kokuqhekeka okucindezelwe kunciphisa umonakalo ovela ku-sulfate crystallization kanye nokwanda.
Ukuqina kokuncibilika kweqhwa: Ukuguquguquka kwefayibha kudonsa ingcindezi ekwakhekeni kweqhwa, kunciphise ukugqagqana kwendawo.

4. Izici Eziyinhloko Ezinomthelela

I-Fiber dosage: Ibanga elilungile liyi-0.5% -2% (ngevolumu); imicu eyeqile idala ukuhlangana nokuncipha kokubumbana.
Ubude befayibha nokusabalalisa: Imicu emide (12–24 mm) ithuthukisa ukuqina kodwa idinga ukusatshalaliswa okufanayo.
Ikhwalithi yokuhlanganisa okugaywe kabusha: Ukumuncwa kwamanzi okuphezulu noma okuqukethwe kodaka olusalela kwenza buthaka ukubopha kwe-fiber-matrix.

5. Okutholakele ocwaningweni kanye neziphetho ezisebenzayo

Imiphumela emihle: Ucwaningo oluningi lukhombisa ukuthi kufanelekilei-fiberglassUkwengeza kuthuthukisa kakhulu ukungangeni, ukumelana ne-chloride, nokumelana ne-sulfate. Isibonelo, i-fiberglass engu-1% inganciphisa ama-coefficients okusabalalisa i-chloride ngo-20%–30%.
Ukusebenza kwesikhathi eside: Ukuqina kwemicu ezindaweni ezine-alkali kudinga ukunakwa. Izingubo ezimelana ne-alkali noma imicu eyingxube (isb., ene-polypropylene) ithuthukisa impilo ende.
Imikhawulo: Izilinganiso ezigaywe kabusha zekhwalithi engalungile (isb., i-porosity ephezulu, ukungcola) zinganciphisa izinzuzo zefayibha.

6. Izincomo Zokusebenza

Izimo ezifanele: Izindawo zasolwandle, inhlabathi enosawoti, noma izakhiwo ezidinga ukhonkolo ophinde wagaywa kabusha ohlala isikhathi eside.
Ukulungiselela ukuxuba: Imithamo yokuhlola ifayibha, isilinganiso esigaywe kabusha sokushintshwa kwe-aggregate, nama-synergies anezithasiselo (isb., i-silica fume).
Ukulawulwa kwekhwalithi: Qinisekisa ukuhlakazeka kwefayibha efanayo ukuze ugweme ukunqwabelana ngesikhathi sokuxutshwa.

Isifinyezo

I-Fiberglass ithuthukisa ukumelana nokuguguleka kukakhonkolo ogaywe kabusha ngokuqiniswa ngokomzimba kanye nokuzinza kwamakhemikhali. Ukusebenza kwayo kuncike ohlotsheni lwefayibha, umthamo, kanye nekhwalithi ehlanganisiwe egaywe kabusha. Ucwaningo lwesikhathi esizayo kufanele lugxile ekuqineni kwesikhathi eside kanye nezindlela zokukhiqiza ezingabizi kakhulu ukuze kube lula izinhlelo zokusebenza zobunjiniyela ezinkulu.
