Amanzi anciphisa i-superplastimizer ekwakheni

Ukunciphisa amanzi okunciphisa amanzi kuyizengezo ezibalulekile embonini yezokwakha, ikakhulukazi ezakhiweni zokhonkolo. Lezi zinhlamvu zenzelwe ukuthuthukisa ukusebenziseka kwezingxube zikakhonkolo ngenkathi kunciphisa okuqukethwe kwamanzi, okuholela ekutheni amandla athuthukisiwe, ukuqina, nezinye izakhiwo ezifiselekayo. Nazi izici ezibalulekile zokunciphisa amanzi ama-superplastizers ekwakheni:

1. Ukuchazwa kanye nokusebenza:

• Ukunciphisa amanzi superplastikizer: Ukuhlanganiswa okuvumela ukuncishiswa okukhulu kokuqukethwe kwamanzi okuxuba ukhonkolo ngaphandle kokuyekethisa ukusebenza kwayo. Ama-superplastizer asabalalisa izinhlayiya zosekhukhwini kahle, okuholela ekuhambeni okuthuthukile nokuvunyelwa okuncishisiwe.

2 Imisebenzi ebalulekile:

• Ukuncishiswa kwamanzi: Umsebenzi oyinhloko ukunciphisa isilinganiso samanzi-ukuya kumasimende ku-conkcrete ukuxubeka, okuholela emandleni aphezulu nokuqina.
• Ukusebenza okuthuthukisiwe: Ama-Superplastimizer athuthukisa ukusebenziseka kokhonkolo ngokuthuthukisa ukuhamba kwawo, okwenza kube lula ukubeka nasekwakhekeni.
• Amandla akhuphuke: Ngokunciphisa okuqukethwe kwamanzi, ama-superplastifizers anikela ngamandla kakhonkolo aphakeme, womabili amandla okucindezela nokuguquguquka.
• Ukuqina okuthuthukile: Ukuhlanganiswa okuthuthukile kanye nokuvumela okuncishisiwe kufaka isandla ekuweni kukakhonkolo, okwenza kube ukumelana nezici zezemvelo.

3. Izinhlobo zama-superplastizer:

• I-Sulfonated Melamine-OrganityDehyde (SMF): eyaziwa ngokunciphisa amandla ayo aphezulu okunciphisa amanzi kanye nokugcinwa okuhle kokusebenza.
• I-Naphthalenated Naphlalene-Formatdehyde (SNF): Inikeza izakhiwo ezinhle kakhulu zokusabalalisa futhi iyasebenza ekunciphiseni okuqukethwe kwamanzi.
• I-Polycarboxylate Ether (PCE): Yaziwa Ngokusebenza Kwayo Okuphezulu Kwamanzi, Ngisho Namanani Amanani Amancane, futhi asetshenziswa kabanzi ngokhonkolo osebenza kakhulu.

4. Izinzuzo:

• Ukusebenza okuthuthukisiwe: Ama-Superplastizer adlulisela ukusebenzela okuphezulu kokuxubeka kokhonkolo, okwenza ukuba agcwaliseke kakhulu futhi kube lula ukusiphatha ngesikhathi sokubekwa.
• Okuqukethwe kwamanzi okuncishisiwe
• Ukubumbana okuthuthukile: Ama-Superplastifizers athuthukisa ukubumbana kwe-conkcrete mix, evumela ukuhlanganiswa okungcono ngaphandle kokuhlukaniswa.
• Ukuhambisana nama-admixtures: Ama-Superplastizers ajwayele ukuhambisana nezinye ama-admixtures ekhonkolo, okuvumela ukwakheka okuguquguqukayo nokwenziwe ngezifiso.
• Amandla okuqala aphezulu: Amanye ama-superplastimizer angafaka isandla ekuhlelweni okusheshayo nasekuthuthukiseni amandla kusenesikhathi ngokhonkolo.

5. Izindawo zohlelo lokusebenza:

• Ukhonkolo olungiselelwe kahle: Ama-superplastimizer asetshenziswa kakhulu ekukhiqizweni kukakhonkolo olungiselelwe ukuxuba ukuthuthukisa ukugeleza kwawo nokusebenza ngesikhathi sokuhamba nokubekwa.
• Ukhonkolo osebenza kakhulu: Kuhlelo lokusebenza lapho amandla aphezulu, ukuqina, kanye nokuqina okuphansi kubalulekile, njengokuhlangana kokhonkolo okuphezulu.
• I-Prerast and Prestressed Concrete: Ama-superplastimizer ajwayele ukusetshenziselwa ukukhiqizwa kwe-prerast kanye nezinto zokhonkolo ezifakwe phambili lapho amandla aphezulu asezingeni eliphakeme futhi amandla okuqala aqakathekile.

6. Imithamo kanye nokuhambisana:

• Umthamo: umthamo ofanele we-superplastimizer uncike ezintweni ezifana nomklamo wokuxuba, uhlobo lwesimende, kanye nezimo zemvelo. Umthamo owedlulele kufanele ugwenywe.
• Ukuvumelana: Ama-Superplastifizer kufanele ahambisane nezinye ama-admixtures ekhonkolo asetshenziswe kuxube. Ukuhlolwa kokuhambisana kuvame ukwenziwa ukuze kuqinisekiswe ukuthi inhlanganisela ye-admixtures yenza njengoba kuhlosiwe.

7. Ukucatshangelwa:

• Mix Design: Idizayini efanelekile yokuxuba, ecubungula uhlobo loseyili, ama-aggregates, kanye nezimo zemvelo, kubalulekile ukusetshenziswa okusebenzayo kwama-superplastizer.
• Imikhuba Yokuphulukisa: Izindlela zokulapha zidlala indima ekuzuzeni izakhiwo ezifiselekayo zikakhonkolo. Ukwelashwa okwanele kubalulekile ekuthuthukisweni kwamandla okuhle.

Ukunciphisa amanzi ama-superplastifizer kuthinte kakhulu imboni kakhonkolo ngokunika amandla ukukhiqizwa kokhonkolo osebenza kahle ngokusebenza okuthuthukile, amandla, nokuqina. Ukuqonda okufanele izinhlobo zabo, imisebenzi, kanye nemihlahlandlela yohlelo lokusebenza kubalulekile ukuze kufinyelelwe imiphumela efanelekile ekwakhiweni kokhonkolo.
