UHLELO OLUPHAKAMILEYO ISINCIBI SAMANZI (SMF)yi-anion enyibilikayo emanzini ephezulu -polymer medium yombane.I-SMF ine-adsorption eyomeleleyo kunye nefuthe lokwabela amagunya kwisamente.I-SMF yenye ye-schizes yequla kwi-arhente ekhoyo yokunciphisa amanzi ekhonkrithi.Iimpawu eziphambili zezi: ezimhlophe, izinga eliphezulu lokunciphisa amanzi, uhlobo lwe-non-air induction, umxholo we-ion ye-chloride ephantsi ayivuthwanga kwiintsimbi zetsimbi, kunye nokulungelelaniswa kakuhle kwi-samente eyahlukeneyo.Emva kokusebenzisa i-ejenti yokunciphisa amanzi, ukuqina kwangaphambili kunye nokunyanzeliswa kwekhonkrithi kwanda kakhulu, izakhiwo zokwakha kunye nokugcinwa kwamanzi kwakungcono, kwaye ukulungiswa kwe-steam kwahlengahlengiswa.
Kwi-concrete slump ngokusisiseko imeko efanayo inokunciphisa kakhulu umxube wamanzi oxutywayo obizwa ngokuba yi-agent ephezulu yokunciphisa amanzi. Kwimeko efanayo ukudilika kwekhonkrithi efanayo, ukuxuba kunye nokusetyenziswa kwamanzi kunokuncitshiswa ngaphezu kwe-15%.
Uphuhliso imbali:Isizukulwana sokuqala se-agent ephezulu yokunciphisa amanzi kunye ne-amine resin-based superplasticizer yaphuhliswa ekuqaleni kwe-1960s.Ngenxa yokusebenza kwe-arhente yokunciphisa amanzi eqhelekileyo yi-lignesulfonate eyaphuhliswa ekupheleni kwe-1930s, ikwabizwa ngokuba yi-plasticizer ephezulu.Isizukulwana sesibini esiphezulu sokunciphisa amanzi si-amino sulfonate, nangona ngokulandelelana kwexesha emva kwesizukulwana sesithathu se-superplasticizer - polycarboxylic. uthotho acid.I-graft copolymer ene-asidi ye-sulfonic kunye ne-carboxylic acid yeyona nto ibalulekileyo kwisizukulwana sesithathu se-arhente yokunciphisa amanzi, kwaye ukusebenza kwayo kukwayeyona arhente yokunciphisa amanzi.
Iintlobo eziphambili:Isantya esiphezulu sokunciphisa amanzi sinokufikelela kwi-20%.Ubukhulu becala luchungechunge lwe-naphthalene, uchungechunge lwe-melamine kunye ne-arhente yokunciphisa amanzi eyenziwe ngabo, phakathi kwayo uchungechunge lwe-naphthalene luphambili, lubalelwa kwi-67%.Ngokukodwa, uninzi lwezixhobo eziphezulu zokunciphisa amanzi zisekwe kwi-naphthalene njengeyona nto iphambili ekrwada.Ngokomxholo we-Na2SO4 kwi-superplasticizer series ye-naphthalene, inokwahlulwa ibe yimveliso yoxinaniso ephezulu (i-Na2SO4 umxholo <3%), iimveliso zoxinaniso oluphakathi (umxholo we-Na2SO4 3% -10%) kunye neemveliso eziphantsi (umxholo we-Na2SO4> 10%). .Uninzi lwezityalo ze-naphthalene superplasticizer synthesis ziyakwazi ukulawula umxholo we-Na2SO4 ngaphantsi kwe-3%, kwaye amanye amashishini aphambili angakwazi ukulawula umxholo we-NA2SO4 ngaphantsi kwe-0.4%.
Uchungechunge lwe-Naphthalene ye-arhente yokunciphisa amanzi yeyona nto inkulu kwimveliso yelizwe lethu, eyona nto isetyenziswa kakhulu i-arhente yokunciphisa amanzi esebenzayo (ibalelwa ngaphezu kwe-70% yesixa se-arhente yokunciphisa amanzi), ebonakaliswa yizinga eliphezulu lokunciphisa amanzi (15% ~ 25%), akukho moya, isiphumo esincinci kwixesha lokumisela, ukuziqhelanisa kakuhle nesamente, kunokusetyenziswa kunye nezinye iikhompawundi ezahlukeneyo zokongeza, ixabiso likwancinci.I-Naphthalene superplasticizer isoloko isetyenziselwa ukulungiselela ikhonkrithi kunye nokuhamba okuphezulu, amandla aphezulu kunye nokusebenza okuphezulu.Ilahleko yekhonkrithi ene-naphthalene superplasticizer ikhawuleza.Ukongeza, ukulungelelaniswa kochungechunge lwe-naphthalene yokunciphisa amanzi kunye nesamente ethile kufuneka iphuculwe.
Iinkcazelo ngeempawu:i-agent ephezulu yokunciphisa amanzi inefuthe elinamandla lokusasazeka kwi-samente, inokuphucula kakhulu ukuhamba komxube we-samente kunye ne-concrete slump, ngelixa unciphisa kakhulu ukusetyenziswa kwamanzi, ukuphucula kakhulu ukusebenza kwekhonkrithi.Kodwa enye i-superplasticizer iya kukhawulezisa ilahleko yekhonkrithi, ukuxubana kakhulu kuya kukopha amanzi.I-arhente yokunciphisa amanzi esebenzayo ngokusisiseko ayitshintshi ixesha lokumisela ikhonkrithi, kwaye inesiphumo esincinci sokunciphisa xa idosi inkulu (ngaphezu kokufakwa kwedosi), kodwa ayilibazisi ukukhula kwamandla okuqala kwekhonkrithi eqinile.
Inokunciphisa kakhulu ukusetyenziswa kwamanzi kunye nokuphucula kakhulu amandla ekhonkrithi kwiminyaka eyahlukeneyo.Xa amandla egcinwa rhoqo, i-samente inokugcinwa nge-10% okanye ngaphezulu.
Umxholo we-chloride ion uncinci, akukho mpembelelo ye-corrosion kwi-bar yensimbi.Inokomeleza ukunganyibiliki, ukuchasana nokunyibilika komkhenkce kunye nokumelana nomhlwa kwekhonkrithi, kunye nokuphucula ukuqina kwekhonkrithi.
