Isisithombe sesikhumba se-Z275 sokusebenzisa imithwalo yasezulwini esinamandla okungafani | Isikhumba sokusebenzisa imithwalo yasezulwini esinamandla okungafani ngeminyaka eyi-25 kumashilu ephambili | Sifanele kumaprojekthi we-solar emazweni esikhaleni, emazweni esihlangu, nokuziphatha kwezindawo zokusebenza zokuphelela
Umhlaba uyayisisekelo okuningi kunezulu. Umshini wokugcina owenziwe ngokuphakama kwezindawo zokusebenza, owayisikhiwe kumhlaba ongavuthi (pH 4.5–5.5), umhlaba wokugcina wokuhamba kwezindawo zokusebenza, noma umhlaba wokugcina wokuhamba kwezindawo zokusebenza, ungalahlela ukuthi ubuyiswe ngokuphakama kwezindawo zokusebenza kusukela emva kwezindawo zokusebenza ngokuphakama kwezindawo zokusebenza. Umshini wokugcina we-C3 wokuthi wasebenza ngokuphakama kwezindawo zokusebenza kulezi zindawo zingalahlwa ngokuphakama kwezindawo zokusebenza kusukela emva kwezindawo zokusebenza ngokuphakama kwezindawo zokusebenza — kusukela emva kwezindawo zokusebenza ngokuphakama kwezindawo zokusebenza.
Isistimu yomshini wokugcina we-Z275 C4-Grade yokuvimbela ukuthi isebenze ngokuphakama kwezindawo zokusebenza yenzelwe ukusebenza kwezindawo zokusebenza eziningi kakhulu lapho ukuthi kwenziwe ngokuphakama kwezindawo zokusebenza kungafanele. Isifundo se-Z275 sokuqala kusiza ukuthi kubekwe i-zinc ngokuphakama kwezindawo zokusebenza — ngokuphakama kwezindawo zokusebenza kusukela emva kwezindawo zokusebenza ngokuphakama kwezindawo zokusebenza — kusukela emva kwezindawo zokusebenza ngokuphakama kwezindawo zokusebenza.
Ngaphandle kwezindawo zokufaka izinkampani, le sistimu ihlanganisa imithambo emibili eyodwa yokulinda ukungena kwezilwane:
Ukubhalwa kwezinkampani zezinc-neziluminum: Ukufaka kwe-Z275 kufaka i-aluminum esingama-5% ekhaya lasezinc, kwenza indawo engeziwe, enobugcwele kakhulu phakathi kwezilwane nezinkampani ezingenakukhona ukungena kwezilwane ngaphakathi kwezinkampani
Ukufaka kwesibonelo se-epoxy: Kumaqondo ase-C4+ no-C5, isibonelo se-epoxy sifakwa phezu kwe-Z275 yasezilwane kuhlelo lwesikhundla esiphakathi kwesandla, kusinika isistimu yesibarrieri esibili
Isikhundla sokusebenzisa umkhosi wokuphela: Kumaqondo amaningi (umfula wezilwane, umfula wokuphela wesandla, umfula ophelile ngezilwane), umkhosi wokuphela we-magnesium ushaya kusinika ukulinda okuphambili kwezilwane ngokuphambili kwezinkampani kuphela

Q. Ngazi kanjani ukuthi ngidinga i-Z275 esikhundleni sokushisela okujwayelekile?
Sincoma i-Z275 C4 grade uma umbiko wakho we-geotechnical ubonisa noma yikuphi kwalokhu okulandelayo: ukumelana kwenhlabathi ngaphansi kuka-2 000 Ω·cm, i-pH ngaphansi kuka-5.0, i-chloride ngaphezu kuka-500 ppm, noma uma iphrojekthi ikude namakhilomitha ama-5 ukusuka ogwini lol Ithimba lethu lonjiniyela lingahlola idatha yakho ye-geotechnical futhi linikeze izincomo zokumboza ngaphandle kwezindleko.
Q. Ingabe isembozo sesisekelo se-epoxy siyathinta ikhono lesikulufo sokushayela?
I-epoxy isetshenziswa kuphela ngemva kokuba isikulufa sesishayelwe ekujuleni kokugcina, njengendlela yokwelashwa ngemuva kokufakwa engxenyeni evezwe ngaphezu kwe-grade kanye nendawo yokuhlangana kwenhlabathi. Njengendlela ehlukile, izikrufu ezifakwe ungqimba lwe-fusion-bonded epoxy (FBE) ezisetshenziswa efektri ziyatholakala kumaphrojekthi lapho ungqimba lwangemva kokufakwa lungasebenzi.
