Ingcaciso yeMveliso:
I-Polycarboxylate superplasticizer (PCE), ekwabizwa ngokuba yi-polycarboxylate ether superplasticizer, sisizukulwana esitsha somxube wekonkrithi osebenza kakhulu. I-arhente yokunciphisa amanzi kunye nokusebenza okugqwesileyo okuhlanganisa ukucuthwa kwamanzi, ukukhuselwa kwe-slump, ukuqiniswa, ukuncipha kunye nokukhuselwa kwendalo. Kwakhona i-admixture efanelekileyo yokulungiswa kwamandla aphezulu, i-concrete ephezulu yokusebenza. Njengohlobo lwe-superplasticizer ethandwayo yekhonkrithi, i-admixture esekelwe kwi-PCE inokusetyenziswa ngokubanzi kwezi projekthi, ezifana nokugcinwa kwamanzi, amandla ombane, amachweba, umzila kaloliwe, ibhulorho, uhola wendlela kunye ne-buldings, njl.
Isicelo:
1. PEC Powder. I-PCE powder yimpuphu equkuqelayo, enesanti, eyomileyo etshizwayo. Ineempawu zokucoleka okuphezulu, i-dispersibility egqwesileyo, umxholo wegesi ephantsi, ukuguquguquka okuhle kunye neesamente ezahlukeneyo, kunye nokuphuculwa kolwelo lodaka, njl. izixhobo. Ipolycarboxylate powder ikwayeyona nto ibalaseleyo yokusasaza iplastiki kwizinto ezimbiwa phantsi ezifana negypsum kunye neekeramics.
2. UkuNcitshiswa kwamanzi aphezulu. I-PCE yokunciphisa amanzi yi-superplasticizer esele ilungele ukusetyenziswa. Ikhanya tyheli ngenkangeleko. Ngaphandle koko, inokuba ngamanzi ngokupheleleyo ngokulula. Ukuphumelela kokunciphisa amanzi kwi-PCE admixture yekhonkrithi inokufikelela kwi-25%. Isetyenziswa kakhulu kumashishini ekhonkrithi esele ilungile kunye ne-precast apho ukuqina okuphezulu kunye nokusebenza kuyadingeka.
3. High Slump Ukugcinwa. I-PCE-High Slump Retention sisizukulwana esitsha se-superplasticizer sekhonkrithi. Iqulethe iipolymers ze-polycarboxylate ether kwaye zenziwe ngokukodwa kwikhonkrithi esele ilungile apho ukugcinwa kwe-slump, amandla aphezulu kunye nokuqina kuyadingeka kwiindawo ezishushu. Ayinayo i-chloride, idibana ne-SS EN 934, Misela ukubuyisela umva / uluhlu oluphezulu lokunciphisa amanzi / i-superplasticizing admixtures, kunye neemfuneko ze-ASTM C 494 zoHlobo lwe-F & G. Kwakhona iyahambelana nazo zonke iisementi ezidibana nemigangatho ye-ASTM. Njengomxube ofanelekileyo kumashishini ekhonkrithi esele ilungile, i-PCE superplasticizer inamandla okusebenza ngamanani aphantsi amanzi / isamente kwaye isafumana ukugcinwa kwe-slump eyandisiweyo ukwenza ikhonkrithi ekumgangatho ophezulu.
Iphakheji: 25 kgs / ibhegi okanye njengoko ucela.
Ugcino: Gcina kwindawo engenamoya, eyomileyo.
Imigangatho eyenziweyo: iMigangatho yeHlabathi.
