I-Sulfoaluminate Cement

I-Sulfoaluminate Cement (SAC) iwuhlobo lukasimende oluthola ukuduma ngenxa yezakhiwo zalo eziyingqayizivele kanye nezinzuzo ngaphezu kwezinye izinhlobo zikasimende. I-SAC iyisimende esebenza nge-hydraulic eyenziwe ngokuhlanganisa i-sulphoaluminate clinker, i-gypsum, kanye nenani elincane le-calcium sulfate. Kulesi sihloko, sizohlola imvelaphi, izici, izinzuzo, nokusetshenziswa kukasimende we-sulphoaluminate.

Origins Sulphoaluminate Cement yasungulwa okokuqala eShayina ngeminyaka yawo-1970. Ekuqaleni yayisetshenziselwa izinhlelo ezikhethekile, ezifana nokhonkolo obeka ngokushesha kanye nodaka lokulungisa. Eminyakeni yakamuva, i-SAC ithole ukuduma njengendlela ehlukile esimeme kunosimende wendabuko wasePortland.

Izici I-Sulfoaluminate Cement inezici ezimbalwa ezihlukile eziyenza ihluke kwezinye izinhlobo zikasimende. Lezi zici zihlanganisa:

1. Ukusetha okusheshayo: I-SAC isetha ngokushesha, nesikhathi sokumisa esingaba yimizuzu eyi-15-20. Lokhu kuyenza ifaneleke ezinhlelweni zokusebenza lapho ukulungiselelwa okusheshayo kudingwa khona, njengalapho kubanda noma lapho kudingekile ukulungisa ngokushesha.
2. Amandla aphezulu aphezulu: I-SAC inamandla amakhulu okuqala, namandla acindezelayo acishe abe ngu-30-40 MPa ngemva kosuku olulodwa lokwelapha. Lokhu kuyenza ilungele izinhlelo zokusebenza lapho amandla angaphambi kwesikhathi edingeka khona, njengakukhonkolo osakazwa ngaphambili noma ukulungisa.
3. I-low carbon footprint: I-SAC ine-carbon footprint ephansi kunosimende wendabuko wase-Portland, njengoba idinga amazinga okushisa aphansi ngesikhathi sokukhiqiza futhi iqukethe i-clinker encane.
4. Ukumelana ne-sulfate ephezulu: I-SAC inokumelana okuphezulu nokuhlasela kwe-sulfate, okuyenza ifanelekele ukusetshenziswa ezindaweni ezine-sulfate ephezulu, njengezindawo ezisogwini.

Izinzuzo Sulphoaluminate usimende inikeza izinzuzo eziningana phezu kwezinye izinhlobo usimende, kuhlanganise:

1. I-carbon footprint eyehlisiwe: I-SAC ine-carbon footprint ephansi kunosimende wendabuko wase-Portland, okuyenza ibe inketho esimeme yokwakha.
2. Ukusetha okusheshayo: I-SAC isetha ngokushesha, engonga isikhathi futhi yehlise izindleko zokwakha.
3. Amandla angaphambi kwesikhathi aphezulu: I-SAC inamandla amakhulu okuqala, anganciphisa isikhathi esidingekayo sokwelapha kanye nokwandisa umkhiqizo.
4. Ukumelana ne-sulfate ephezulu: I-SAC inokumelana okuphezulu nokuhlasela kwe-sulfate, okungakhuphula ukuqina kwezakhiwo zekhonkrithi ezindaweni ezinokhahlo.

Isebenzisa usimende we-Sulphoaluminate usetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi:

1. Ukhonkolo wokusetha ngokushesha: I-SAC ivamise ukusetshenziswa ezinhlelweni lapho ukusetha okusheshayo kudingeka khona, njengalapho kubanda noma ukulungisa ngokushesha.
2. Ukhonkolo osakazwa ngaphambili: I-SAC ivame ukusetshenziswa ekukhiqizeni imikhiqizo kakhonkolo, njengamapayipi kakhonkolo, ama-slabs, namaphaneli.
3. Udaka lokulungisa: I-SAC ivame ukusetshenziswa njengodaka lokulungisa izakhiwo zikakhonkolo, njengoba lusetha ngokushesha futhi lunamandla aphezulu okuqala.
4. Ukhonkolo ozilinganisa ngokwawo: I-SAC ingasetshenziselwa ukukhiqiza ukhonkolo ozilinganisa, olungele izinhlelo zokusebenza lapho kudingeka khona indawo ebushelelezi, enezinga eliphezulu.

Isiphetho I-Sulphoaluminate Cement iwuhlobo oluhlukile lukasimende olunikeza izinzuzo ezimbalwa kunosimende wendabuko wasePortland. Ine-carbon footprint ephansi, isetha ngokushesha, inamandla amakhulu okuqala, futhi imelana kakhulu nokuhlaselwa kwe-sulfate. I-SAC isetshenziswa kuzinhlelo zokusebenza ezahlukahlukene, kufaka phakathi ukhonkolo omiswa ngokushesha, ukhonkolo osakazwa ngaphambili, udaka lokulungisa, kanye nokhonkolo ozilinganisa. Njengoba ukusimama kuba ukucatshangelwa okubaluleke kakhulu ekwakhiweni, ukusetshenziswa kwe-SAC kungenzeka kukhule ekudumeni.
