ISINCIPHISO SAMANZI ESIPHAKAMILEYO (SMF)yi-anion enyibilikayo emanzini ene-polymer ephezulu. I-SMF ine-adsorption enamandla kunye nefuthe elisezantsi kwisamente. I-SMF yenye yee-well-schizes kwi-arhente yokunciphisa amanzi yekhonkrithi ekhoyo. Iimpawu eziphambili zezi: umhlophe, izinga eliphezulu lokunciphisa amanzi, uhlobo lokungenisa umoya olungenamoya, umxholo we-ion ye-chloride ephantsi awugqwalanga kwiibha zentsimbi, kunye nokuzivumelanisa kakuhle nesamente eyahlukeneyo. Emva kokusebenzisa i-arhente yokunciphisa amanzi, ukuqina kokuqala kunye nokuvuleka kwekhonkrithi kwanda kakhulu, iipropati zokwakha kunye nokugcinwa kwamanzi zazingcono, kwaye ukugcinwa komphunga kwahlengahlengiswa.
Xa kukho ukuwohloka kwekhonkrithi, imeko efanayo inokunciphisa kakhulu umxube wamanzi oxutywayo obizwa ngokuba yi-arhente yokunciphisa amanzi esebenza kakuhle. Kwimeko efanayo, ukuwohloka kwekhonkrithi, ukuxuba kunye nokusetyenziswa kwamanzi kunokunciphisa ngaphezulu kwe-15%.
Uphuhliso imbali:Isizukulwana sokuqala se-arhente yokunciphisa amanzi esebenza kakuhle kakhulu kunye ne-superplasticizer esekelwe kwi-amine resin yaphuhliswa ekuqaleni kweminyaka yoo-1960. Ngenxa yokusebenza kwe-arhente yokunciphisa amanzi eqhelekileyo yi-lignesulfonate eyaphuhliswa ngasekupheleni kweminyaka yoo-1930, ikwaziwa njenge-superplasticizer. Isizukulwana sesibini se-arhente yokunciphisa amanzi esebenza kakuhle kakhulu yi-amino sulfonate, nangona ngokwexesha emva kwesizukulwana sesithathu se-superplasticizer - uthotho lwe-polycarboxylic acid. I-graft copolymer ene-sulfonic acid kunye ne-carboxylic acid yeyona ibalulekileyo kwisizukulwana sesithathu se-arhente yokunciphisa amanzi esebenza kakuhle kakhulu, kwaye ukusebenza kwayo kukwayeyona arhente yokunciphisa amanzi esebenza kakuhle kakhulu.
Iintlobo eziphambili:Izinga lokunciphisa amanzi le-arhente yokunciphisa amanzi esebenza kakuhle linokufikelela ngaphezulu kwama-20%. Ngokuyintloko luchungechunge lwe-naphthalene, uthotho lwe-melamine kunye ne-arhente yokunciphisa amanzi eyenziwe ngazo, phakathi kwazo uthotho lwe-naphthalene lolona luphambili, olubalelwa kuma-67%. Ngokukodwa, uninzi lwee-arhente zokunciphisa amanzi ezisebenzayo kakhulu zisekelwe kwi-naphthalene njengezinto eziphambili zokwenza imveliso. Ngokwesiqulatho se-Na2SO4 kwi-naphthalene series superplasticizer, inokwahlulwa ibe ziimveliso zoxinzelelo oluphezulu (umxholo we-Na2SO4 < 3%), iimveliso zoxinzelelo oluphakathi (umxholo we-Na2SO4 3%-10%) kunye neemveliso zoxinzelelo oluphantsi (umxholo we-Na2SO4 > 10%). Uninzi lwezityalo zokwenziwa kwe-naphthalene superplasticizer zinamandla okulawula umxholo we-Na2SO4 ngaphantsi kwe-3%, kwaye amanye amashishini aphambili anokulawula umxholo we-NA2SO4 ngaphantsi kwe-0.4%.
I-Naphthalene series ye-arhente yokunciphisa amanzi yeyona inkulu kwilizwe lethu ekuvelisweni kwayo, yeyona isetyenziswa kakhulu njenge-arhente yokunciphisa amanzi esebenza kakuhle (ebala ngaphezulu kwe-70% yenani le-arhente yokunciphisa amanzi), ebonakaliswa yizinga eliphezulu lokunciphisa amanzi (15% ~ 25%), akukho moya, impembelelo encinci kwixesha lokuseta, ukulungelelana okuhle ngesamente, ingasetyenziswa kunye nezinye izongezo ezahlukeneyo, ixabiso likwaphantsi kakhulu. I-Naphthalene superplasticizer idla ngokusetyenziselwa ukulungisa ikhonkrithi enokuhamba okuphezulu, amandla aphezulu kunye nokusebenza okuphezulu. Ukulahleka kwekhonkrithi nge-naphthalene superplasticizer kukhawuleza. Ukongeza, ukulungelelana kwe-naphthalene series water reducing agent kunye nesamente ethile kufuneka kuphuculwe.
Iipropati:I-arhente yokunciphisa amanzi esebenza kakuhle kakhulu inefuthe elikhulu lokusasazeka kwisamente, inokuphucula kakhulu ukuhamba komxube wesamente kunye nokuwa kwekhonkrithi, ngelixa inciphisa kakhulu ukusetyenziswa kwamanzi, iphucule kakhulu ukusebenza kwekhonkrithi. Kodwa enye i-superplasticizer iya kukhawulezisa ukulahleka kwekhonkrithi, ukuxuba kakhulu kuya kuphuma amanzi. I-arhente yokunciphisa amanzi esebenza kakuhle ayitshintshi ixesha lokuseta ikhonkrithi, kwaye inefuthe elincinci lokulibazisa xa idosi inkulu (ukufakwa kwedosi engaphezulu), kodwa ayilibazisi ukukhula kwamandla kwangoko kwekhonkrithi eqinileyo.
Inganciphisa kakhulu ukusetyenziswa kwamanzi kwaye iphucule kakhulu amandla ekhonkrithi kwiminyaka eyahlukeneyo. Xa amandla ehlala engaguquki, isamente ingagcinwa nge-10% nangaphezulu.
Umxholo we-chloride ion mncinane, akukho mpembelelo yokugqwala kwintsimbi. Ingaphucula ukungenwa kwamanzi, ukumelana nokuqandusela komkhenkce kunye nokumelana nokugqwala kwekhonkrithi, kwaye iphucule ukuqina kwekhonkrithi.
