Impembelelo yeFiberglass kwiNgxaki yokuKhukuliseka kweConcrete eRisayikilishiweyo

Impembelelo yefiberglass ekuchaseni ukukhukuliseka kwekhonkrithi esetyenzisiweyo (eyenziwe ngee-aggregates zekhonkrithi esetyenzisiweyo) ngumxholo onomdla kakhulu kwisayensi yezinto kunye nobunjineli bokwakha. Nangona ikhonkrithi esetyenzisiweyo inika iingenelo zokusingqongileyo kunye nokurisayikilisha izixhobo, iimpawu zayo zoomatshini kunye nokuqina kwayo (umz., ukuchasana nokukhukuliseka) zihlala zingaphantsi kunekhonkrithi eqhelekileyo. I-Fiberglass, njengesixhobo sokwakha.izinto zokuqinisa, inokuphucula ukusebenza kwekhonkrithi ephinda isetyenziswe ngeendlela ezibonakalayo nezekhemikhali. Nantsi uhlalutyo oluneenkcukacha:

1. Iimpawu kunye nemisebenzi yeIglasi yefayibha

I-Fiberglass, into engeyoyasemethini engaphiliyo, ineempawu ezilandelayo:
Amandla aphezulu okutsalwa: Ilungisa amandla aphantsi okutsalwa kwekhonkrithi.
Ukumelana nokugqwala: Iyamelana nokuhlaselwa ziikhemikhali (umz., ii-ion ze-chloride, ii-sulfates).
Ukuqina nokumelana neentanda**: Ivala iintanda ezincinci ukuze ilibazise ukusasazwa kweentanda kwaye inciphise ukungena kwamanzi.

2. Iingxaki zokuqina kwekhonkrithi ephinde yasetyenziswa

Izinto eziphinda zisetyenziswe ezine-residual samente paste ezinamagqabi kwiindawo zazo zikhokelela koku:
Indawo yokutshintshana kwe-interfacial ebuthathaka (ITZ): Ubudlelwane obubi phakathi kwezinto ezisetyenzisiweyo kunye ne-samente entsha, nto leyo edala iindlela ezinokuthi zingene.
Ukungangeni manzi okuphantsi: Izinto ezikhukulisayo (umz., Cl⁻, SO₄²⁻) zingena lula, zibangele ukugqwala kwentsimbi okanye umonakalo omkhulu.
Ukumelana nokuqandusela okungekuhle: Ukwanda komkhenkce kwimingxuma kubangela ukuqhekeka nokuqhekeka.

3. Iindlela zeFiberglass ekuPhuculeni ukuxhathisa ukuKhukuliseka

(1) Iziphumo zoMqobo oMzimbeni
Ukuthintela iimfanta: Iifanta ezisasazeke ngokulinganayo zivala iimfantanta ezincinci, zithintela ukukhula kwazo kwaye zinciphise iindlela zezinto ezikhukulisayo.
Ukuqina okuphuculweyo: Iifayibha zizalisa iimbobo, zinciphisa ukubola kwaye zicothise ukusasazeka kwezinto ezinobungozi.

(2) Uzinzo lweeKhemikhali
I-fiberglass engamelani ne-alkali(umz., i-AR-glass): Iifayibha ezicocwe ngaphezulu zihlala zizinzile kwiindawo ezine-alkali eninzi, ziphepha ukubola.
Ukuqinisa ujongano: Ukubopha okuqinileyo kwefayibha-matrix kunciphisa iziphene kwi-ITZ, kunciphisa iingozi zokukhukuliseka kwendawo.

(3) Ukumelana neentlobo ezithile zokuKhukuliseka
Ukumelana nee-ion ze-chloride: Ukwakheka okunciphileyo kweentanda kucothisa ukungena kwe-Cl⁻, kubambezele ukugqwala kwentsimbi.
Ukumelana nokuhlaselwa yi-sulfate: Ukukhula okucinezelweyo kweemfanta kunciphisa umonakalo obangelwa kukwakheka kwe-sulfate crystallization kunye nokwanda kwayo.
Ukuqina kokuqandisa nokunyibilikisa: Ukuguquguquka kwefayibha kutsala uxinzelelo oluvela ekwakhekeni komkhenkce, kunciphisa ukuqhekeka komphezulu.

4. Izinto Eziphambili Ezinefuthe

Umlinganiselo wefayibha: Uluhlu olufanelekileyo yi-0.5%–2% (ngokomthamo); iifayibha ezigqithisileyo zibangela ukuhlangana kunye nokuncipha kobuncinci.
Ubude befayibha kunye nokusasazeka kwayo: Iifayibha ezinde (12–24 mm) ziphucula ukuqina kwayo kodwa zifuna ukusasazwa okufanayo.
Umgangatho wee-aggregates ezisetyenzisiweyo: Ukufunxwa kwamanzi amaninzi okanye umxholo oseleyo we-mortar ubuthathaka ukubopha kwe-fiber-matrix.

5. Iziphumo zoPhando kunye neZigqibo eziSebenzayo

Iziphumo ezilungileyo: Uninzi lwezifundo lubonisa ukuba kufanelekilei-fiberglassUkongeza kuphucula kakhulu ukungakwazi ukungena kwamanzi, ukumelana ne-chloride, kunye nokumelana ne-sulfate. Umzekelo, i-1% fiberglass inokunciphisa ii-coefficients ze-chloride diffusion nge-20%–30%.
Ukusebenza kwexesha elide: Ukuqina kweefayibha kwiindawo ezine-alkaline kufuna ingqalelo. Iingubo ezimelana ne-alkali okanye iifayibha ezixutyiweyo (umz., ezine-polypropylene) ziyandisa ixesha elide.
Imida: Ii-aggregates ezisetyenzisiweyo ezikumgangatho ophantsi (umz., ukuvuleka okuphezulu, ukungcola) zinokunciphisa iingenelo zefayibha.

6. Iingcebiso zeSicelo

Iimeko ezifanelekileyo: Iindawo zaselwandle, umhlaba onetyuwa, okanye izakhiwo ezifuna ikhonkrithi ephinda isetyenziswe eqinileyo.
Ulungelelwaniso lweMix: Vavanya idosi yefayibha, umlinganiselo wokutshintshwa kwe-aggregate ophinda usetyenziswe, kunye nokusebenzisana nezinye izongezo (umz., i-silica fume).
Ulawulo lomgangatho: Qinisekisa ukuba ifayibha iyasasazeka ngokulinganayo ukuze kuthintelwe ukuxinana ngexesha lokuxuba.

Isishwankathelo

I-Fiberglass iphucula ukumelana nokukhukuliseka kwekhonkrithi ephinda isetyenziswe ngokuqinisa ngokwasemzimbeni kunye nokuzinzisa iikhemikhali. Ukusebenza kwayo kuxhomekeke kuhlobo lwefayibha, umthamo, kunye nomgangatho we-recycled aggregate. Uphando lwexesha elizayo lufanele lugxile ekuqineni kwexesha elide kunye neendlela zokuvelisa ezingabizi kakhulu ukuze kube lula usetyenziso olukhulu lobunjineli.
