Impembelelo ye-Figberglass kwi-eRosion Ukunganyangeki kwekhonkrithi ehlaziyiweyo

Impembelelo ye-fiberglass kwimfundiso yokhukuliseko lwekhonkrithi ehlaziyiweyo (eyenziwe kwi-Agegrete eDityanisiweyo yeDisgregates) sisihloko soMdla obalulekileyo kwiSayensi yezixhobo kunye nobuNjineli boBunjineli. Ngelixa ukuphinda usebenzise ikhonkrithi ibonelela ngezibonelelo zokusilisa kwindalo esingqongileyo kunye nezixhobo zokusetyenziswa kwezixhobo, iipropathi zoomatshini kunye nokuqina (umzekelo, ukumelana nokhukuliseko) zihlala ziphantsi kwikhonkrithi yekhonkrithi. I-fiberglass, njengeUkuqinisa izinto, unokuphucula ukusebenza kwekhonkrithi ehlaziyiweyo ngokusebenzisa iindlela zomzimba kunye neekhemikhali. Nalu uhlalutyo olucacileyo:

1. Iipropathi kunye nemisebenzi yeI-fiberglass

I-fiberglass, i-inorganic i-inorganic ye-inollic, ibonise ezi mpawu zilandelayo:
Amandla amakhulu e-sunsle: inyanzela amandla okuqina okuphantsi kwekhonkrithi.
Ukunganyangeki kwe-Corrosion: Thumela ukuhlaselwa kweekhemikhali (umzekelo, i-chloride ion, i-sulfates).
Thumela kunye nokuchasana nokuchasa **: Bridges Microctcts ukulibazisa ukusasazwa kwe-rack kunye nokunciphisa ukuqhutywa.

I-2. Ukunqunyulwa kweentsilelo zekhonkrithi ehlaziyiweyo

I-Aggregates ehlaziyiweyo ye-Aggregates ene-quida ye-paste paltid paste kwimiphezulu yabo ikhokelela:
Indawo yobuthathaka engaqhelekanga (itz): Ukuboleka kakubi phakathi kwe-Aggregates ehlaziyiweyo kunye nesamente entsha inamathisela, ukudala iindlela ezifanelekileyo.
Ukungafezeki kwe-EPER: I-Arhente yokuKhulula (umz.
Ukungaxhathisi-subze-thaw Ukungaxhathisi: Ukwanda kwe-icew kwi-pores ebeka i-poresker kunye nokutshisa.

I-3. Iindlela zeFiberglass ekuphuculeni ukumelana kwe-erosion

(1) Iziphumo zothintelo lomzimba
Isithintelo se-rack: I-fibers engasasazwanga yi-ridges i-bridges, ivimba ukukhula kwazo kunye nokunciphisa iindlela zokuphucula iiarhente zokuzonwabisa.
Ukungathobeki okuphuculweyo: Iintsinga ziyagcwalisa iipores, ukwehlisa ukonakala kwaye kunciphise ukwahluka kwezinto eziyingozi.

(2) Uzinzo lwekhemikhali
I-Alkali-i-fiberglass enganyangekiyo.
Ukunyanzeliswa kwe-interfayili

(3) Ukuchasana neentlobo zezifundo ezithile
Ukunganyangeki kwe-ion ye-chloride ion: Ukuncitshiswa komzimba okucothisayo kuyacotha i-cllopeneling, kulibazisa ukuntywila kwentsimbi.
Ukuhlaselwa kwe-sulfate ukuhlasela: Ukukhula komsindo ocinezelweyo kunciphisa umonakalo ovela kwi-crystalment kunye nokwandiswa.
Ukuqina kwe-freeze-thaw: I-fiber bhembe ifunxa i-surbs yoxinzelelo kwi-ices ye-ice, ukunciphisa umhlaba.

4. Izinto eziphambili zokuphembelela

I-fiber dosage: Uluhlu olufanelekileyo yi-0.5% -2% (ngomthamo); Iintsinga ezigqithisileyo zibangela ukudityaniswa kunye nokuncitshiswa kwengqungquthela.
Ubude be-fiber kunye nokusasazeka: Iintsinga ezinde (12-24 mm) Ukuphucula ukubopha kodwa kufuna ukusasazwa kweyunifomu.
Umgangatho we-Aggregates ye-Aggregates ehlaziyiweyo: Ukufunqwa kwamanzi aphezulu okanye umxholo oshiyekileyo wokufakelwa kwe-fiber-matrix.

5. Iziphumo zophando kunye nezigqibo ezisebenzayo

Iziphumo ezilungileyo: Uninzi lwezifundo zibonisa ukuba kufanelekileI-fiberglassUkongeza ukuphucula ngokucacileyo ukungafezeki, ukunyangwa kwe-chloride, kunye nokunganyangeki kwesal. Umzekelo, i-1% fiberglass inokunciphisa i-chloride ye-chloride ye-chloride i-20% -30%.
Ukusebenza kwexesha elide: Ukuqina kweentsinga kwiindawo zeAlkaline kufuna ingqalelo. I-Alkali-Coants enganyangekiyo okanye i-hybrid fibers (umzekelo, ngePolypropylene) yokuphucula izongezo.
Ukusikelwa umda

6. Iingcebiso zesicelo

Imeko efanelekileyo: Iindawo zaselwandle, imihlaba ye-saline, okanye izakhiwo ezifuna irinzeni ePhakamileyo.
Ulungelelwaniso lwe-fiber, i-fiber yefayibha yovavanyo, iphinde yasebenza kwakhona i-Aggregatiment Gramatiores, kunye ne-Synelargies ngeesayina (umz. I-Silica fume).
Ulawulo loMgangatho: Qinisekisa ukusasazeka kwe-firmorm kwi-fiblerm ukunqanda ukungqubana ngexesha lokuxuba.

Isishwankathelo

I-fiberglass ixhasa ukumelana nokukhukuliseka kwekhonkrithi ehlaziyiweyo ngokutyibilika ngokwasemzimbeni kunye nokuzinza kwemichiza. Ukusebenza kwayo kuxhomekeka kuhlobo lwefayibha, idosi, kunye nokuphinda kusebenze kwakhona umgangatho. Uphando lwexesha elizayo kufuneka lujolise kwizinto zokwenza ixesha elide kunye neendlela zokuvelisa iindleko ukuqhuba izicelo zobunjineli bobunjineli.
