1. I-polycarboxylic acid-based based-high-performance agent-agent agent yokunciphisa amanzi ihluke kwi-naphthalene esekelwe kwi-high-performance-high-performance agent yokunciphisa amanzi kuloo nto:
Eyokuqala yintlukwano kunye nokulungelelaniswa kwesakhiwo se-molecular; okwesibini kukugxila ngakumbi kunye nokuphucula iingenelo ze-ejenti zokunciphisa amanzi ngobuchule obuphezulu, kunye nokufezekisa iinkqubo zemveliso eziluhlaza kunye nokungangcoliseki.
Ukusuka kwindlela yokusebenza, i-molecular structure ye-polycarboxylic acid ye-agent yokunciphisa amanzi ifana nekama. Iqela elinamandla le-polar anionic "i-anchoring" kwikhonkco eliphambili lisetyenziselwa ukubhengeza kwiincinci zesamente. Ikama yangaphandle eyandisiweyo ixhaswa ngamatyathanga amaninzi amasebe. Ulwakhiwo lwezinyo lubonelela ngesiphumo esaneleyo solungiselelo lwesithuba sokusasazwa ngakumbi kwamasuntswana esamente. Xa kuthelekiswa nokunyanzeliswa kombane kombane ophindwe kabini we-naphthalene-based based reduction agents, isithintelo se-steric sigcina ukusabalalisa ixesha elide.
Ngokutshintsha ngokufanelekileyo isakhiwo se-comb se-agent ye-polycarboxylate yokunciphisa amanzi kunye nokutshintsha ngokufanelekileyo ubuninzi kunye nobude bamatyathanga asecaleni, i-agent ephezulu yokunciphisa amanzi kunye ne-early-early-early yokunciphisa amanzi efanelekileyo kumacandelo asele enziwe ngaphambili inokufumaneka.
Iiarhente zokunciphisa amanzi ePolycarboxylic Acid zinokulungiswa kwaye zitshintshwe ngokweemfuno zokufezekisa iinjongo zokutshintsha ukusebenza, kunokuba zisebenzise ukuguqula okulula ukulungiswa. Ngokusekwe kolu kuqonda, kunokusikhuthaza ukuba siphucule itekhnoloji yethu yosetyenziso kwixesha elizayo.
2. Ukuguquguquka kwe-polycarboxylic acid-based-agent yokunciphisa amanzi kwizinto zesamente:
Iindidi ezahlukeneyo zesamente zineendawo zokuzalisa ezahlukeneyo zepolycarboxylic acid-based superplasticizers, ngoko ke kubaluleke kakhulu ukufumana iindawo zokugcwala kweesamente ezahlukeneyo. Nangona kunjalo, ukuba umsebenzisi uchaza ukuba kuphela i-1.0% evunyelwe ukuba yongezwe, ukuba i-samente ekhethiweyo ayiguqukiyo kule dosi, kuya kuba nzima kumboneleli we-admixture ukuyiphatha, kwaye indlela yokudibanisa kaninzi ayinayo impembelelo encinci.
Umlotha wenqanaba lokuqala unokulungelelaniswa kakuhle, ngelixa umlotha wenqanaba lesibini kunye nelesithathu kaninzi awufanelekanga. Ngeli xesha, nangona inani le-polycarboxylic acid linyukile, umphumo awubonakali. Amaxesha amaninzi xa uhlobo oluthile lwesamente okanye uthuthu lwempukane lungakwazi ukuziqhelanisa nengxubevange, kwaye awukaneliseki ngokupheleleyo xa utshintshela kwenye ingxubevange, ekugqibeleni kusenokufuneka ubuyisele imathiriyeli yesamente.
3.Ingxaki yesiqulatho sodaka esantini:
Xa udaka lwesanti luphezulu, izinga lokunciphisa amanzi kwi-polycarboxylate-based based-agent agent liya kuncitshiswa kakhulu. Ukusetyenziswa kwe-naphthalene-based based-reduction agents ivame ukusonjululwa ngokunyusa umthamo, ngelixa i-polycarboxylic acid-based based-agent-agent agents ayitshintshi kakhulu xa idosi yanda. Kwiimeko ezininzi, xa i-fluidity ingafikelelanga kwinqanaba elifunekayo, ikhonkrithi iqalile ukuphuma kwegazi. Ngeli xesha, umphumo wesantya sokulungiswa kwesanti, ukwandisa umxholo womoya okanye ukongeza i-thickener akuyi kuba kuhle kakhulu. Eyona ndlela ingcono kukunciphisa umxholo wodaka.
