I-Superplastikibers isasaza amasuntswana amasuntswana amaninzi, okukhokelela ekuphuculeni ukuhamba okuphuculweyo kwaye kuncitshiswe i-viscofity.

2. Imisebenzi ephambili:

• Ukuncitshiswa kwamanzi: Umsebenzi ophambili kukunciphisa umyinge wamanzi ukuya kwikhonkrithi kwikhonkrithi, ekhokelela kumandla aphezulu kunye nokuqina.
• Ukuphuculwa kokuphuculwa: iindawo ezinqabileyo zokuphucula ukusebenza kwekhonkrithi ngokuphucula ukuhamba kwayo, kwenza kube lula ukubeka kunye nobume.
• Amandla anyukayo: Ngokunciphisa umxholo wamanzi, abenzi bezinto eziphezulu banegalelo kumandla aphezulu ekhonkrithi, zombini malunga nokunyanzelwa nangamandla ecikisi.
• Ukuqina okuphuculweyo: Ukuphuculwa kwento ephuculiweyo kunye nokuncitshiswa kwengqondo yenzekile kwikhonkrithi yekhonkrithi, esenza ukuba ixhathise ngakumbi kwizinto zokusingqongileyo.

I-3. Iindidi ze-Superplastickistit:

• I-Sulfomine-i-formamine-fordehyde (i-SMF): Yaziwa ngokuba ngamanzi ayo anciphisa amanzi kunye nokugcinwa okuhle emsebenzini.
• I-Naphthalene-formaldehyde (SNF): inika iipropathi ezigqwesileyo kwaye ziyasebenza ekunciphiseni umxholo wamanzi.
• I-Polycarboxylated Ether (PCE): Yaziwa ngokuba yimpumelelo yawo enciphisa amanzi, nangamaxabiso asezantsi, kwaye isetyenziswe ngokubanzi kwikhonkrithi yokusebenza ePhakamileyo.

4. Izibonelelo:

• Ukuphuculwa kokuphuculwa: I-Superplasticindizers idlulisela ukusebenza okuphakamileyo kwikhonkrithi, ibenza babe neentyatyambo ngakumbi kwaye kube lula ukuziphatha ngexesha lokubekwa.
• Ukucuthwa komxholo wamanzi: Eyona nto iphambili kukuncitshiswa okukhulu kumlinganiso wesamente wamanzi, okukhokelela kumandla aphuculweyo kunye nokuqina.
• I-cosion ephuculweyo: Iindawo ezinqabileyo zokuphucula ubumbano yomxube wekhonkrithi, zivumela ukudityaniswa okungcono ngaphandle kokwahlulahlula.
• Ukuhambelana nokudityaniswa: I-Superplasticindizes zihlala zihambelana nolunye uhlobo lwekhonkrithi, zivumela ukumiliselwa kwekhonkrithi kunye nokwenziwa ngokwezifiso.
• Amandla aphezulu angaphambili: Ezinye iindawo eziphambili zinokuba negalelo ekumiseleni ngokukhawuleza kunye nophuhliso lwamandla angaphambili kwikhonkrithi.

5. Iindawo zesicelo:

• Ukuxuba ikhonkrithi: Ikhonkrithi ye-Superplastriezers iqhele ukusetyenziswa kwimveliso yekhonkrithi elungiselelwe ukuphucula ukuhamba kwayo kunye nokusebenza ngexesha lokuhamba kunye nokubekwa.
• Ikhonkrithi yokuSebenza ePhakamileyo: Kwizicelo apho amandla aphezulu, ukuqina, kunye nokufana okuphantsi kubalulekile, njengokusebenza kwekhonkrithi ephezulu.
• I-upripy kwaye icinezelwe ikhonkrithi: I-Superplasticindizers zihlala zisetyenziswa kwimveliso ye nqanaba eliqinileyo kwaye icinezelwe lezinto ezibonakalayo apho imigangatho ephezulu yomgangatho kwaye amandla okuqala ibalulekile.

I-6. Umthamo kunye nokuhambelana:

• Umthamo: Umthamo ofanelekileyo webala le-Superplasticiezer uxhomekeke kwizinto ezinje ngoyilo lomxube, uhlobo lwesamente, kunye neemeko zokusingqongileyo. I-dosage egqithisileyo kufuneka ithintelwe.
• Ukuhambelana: Ii-Superpasticiers kufuneka zihambelane nolunye uhlobo lwekhonkrithi elisetyenziswa kumxube. Iimvavanyo zokuhambelana zihlala ziqhutywa ukuqinisekisa ukuba indibaniselwano yokuthambeka kwenziwe njengoko bekucwangcisiwe.

7. Ukuqwalaselwa:

• Hlanganisa uyilo: Ukujonga ngokuchanekileyo uyilo, ukuthathela ingqalelo uhlobo lwesamente, ukwahlula-hlula, kunye neemeko zokusingqongileyo, kubalulekile ukuba zisetyenziswe ngokufanelekileyo.
• Ukuziqhelanisana nokunyangwa: Ukunyanga ukunyanga kudlala indima ekufezekiseni iipropathi eziyifunayo kwikhonkrithi. Unyango olwaneleyo lubalulekile ukuze amandla aphezulu ophuhliso.

Ukunciphisa amanzi e-superplasticciostibecking kuyeyona nto ichaphazela kakhulu ishishini lekhonkrithi ngokunika ukuveliswa kwemveliso ephezulu yekhonkrithi ngokuphuculwa kokusebenza, amandla, kunye nokuqina. Ukuqonda ngokufanelekileyo iintlobo zabo, imisebenzi, kunye nezikhokelo zesicelo kubalulekile ekufezekiseni iziphumo ezifanelekileyo kulwakhiwo lwekhonkrithi.
