I-ejenti yokunciphisa amanzi ngokhonkolo ingenye yezindlela zobuchwepheshe zokunciphisa isikali sikasimende, ukuthuthukisa izinga lokusetshenziswa kwezinsalela zemfucuza yezimboni, kanye nokubona ukuqina nokusebenza okuphezulu kukakhonkolo.Futhi kungenye yezinto ezibalulekile zokuthuthukiswa kokhonkolo kuya emkhakheni wobuchwepheshe obuphezulu.Futhi i-ejenti yokunciphisa amanzi yohlobo lwe-polycarboxylate (i-PC) isiphenduke uhlobo lwe-ejenti yokunciphisa amanzi ephumelelayo enentuthuko esheshayo namandla amakhulu emakethe ngenxa yobuthi bayo obuphansi nezici zokuvikela imvelo.Uma kuqhathaniswa nezixube zendabuko, izingxube seziphenduke into egxile kakhulu ocwaningweni nasekuthuthukisweni komhlaba wonke ngenxa yokuhlakazeka kwazo okuhle kakhulu kanye nekhono lokugcina ukuwohloka.
Nakuba amanzi e-polycarboxylate ehlisa i-admixture ukusebenza okuvelele kanye nekhono lokugcina ukuwohloka okuhle kuye kwaqashelwa kabanzi, kodwa ngenxa yokuba khona kokwakheka kwezimbiwa, ukuqina kukasimende, ifomu likasimende nokuqukethwe, inani le-admixture enezela, kanye nenqubo yokuxuba isilinganiso sengxube kakhonkolo, amanzi. inokuzwela okuphezulu kakhulu, okuthinteke kakhulu imikhiqizo ekhona isetshenziswa kakhulu kwezobunjiniyela.
Iyini i-ejenti yokunciphisa amanzi ye-Polycarboxylate Series?
I-Polycarboxylate superplasticizer iwuhlobo lwe-surfactant equkethe i-carboxylic graft copolymer.Ama-molecule awo anomumo wekamu futhi anomphumela ophakeme wesithiyo.Njengesizukulwane sesithathu se-ejenti yokunciphisa amanzi esebenza kahle kakhulu ngemuva kwe-agent ye-lignosulfonate evamile yokunciphisa amanzi, iqembu le-naphthalene aliphatic, i-sulfamate kanye nezinye i-ejenti yokunciphisa amanzi esebenza kahle kakhulu.
Kungenxa yokuthi ukusebenza kwesakhiwo samangqamuzana kuhle, amanzi anciphisa kakhulu, inani eliphansi lengxubevange, gcina ukuwohloka kukuhle, thuthukisa okuhle, aqukethe inani le-alkali liphansi, ukusetha ithonya lesikhathi lincane, futhi ukuhambisana okuningi kukasimende kuhle futhi akungcolisi futhi ezinye izinzuzo zithathwa njengamandla okuthuthukisa kakhulu ezinhlobonhlobo ze-ejenti yokunciphisa amanzi.
I-Polycarboxylate superplasticizer iyi-superplasticizer entsha esebenza kahle kakhulu eyakhiwe futhi yakhiqizwa ngempumelelo ngemuva kwe-naphthalene, i-melamine, i-aliphatic ne-sulfamate superplasticizer.Kokuqukethwe kwakho kuphansi (okuqukethwe okuqinile 0.15% - 0.25%) kungaveza umphumela ofanelekile wokunciphisa kanye nokuthuthukiswa kwamanzi, umthelela omncane ngesikhathi sokumiswa kokhonkolo nokugcinwa kokuwa, ukuguquguquka kusimende kanye nengxube kuhle uma kuqhathaniswa, umthelela omncane ekomisweni. ukushwabana kukakhonkolo (ngokuvamile akukhulisi kakhulu ukomisa ukuncipha), ngaphandle kokusetshenziswa kwe-formaldehyde ngesikhathi sokukhiqiza futhi akukhiphi uphuzo oludakayo, SO Okuqukethwe okuphansi kwe-42- kanye ne-Cl- kuye kwanconywa abacwaningi nabanye abasebenzisi kusukela ukuqala.
Kungani kufanele i-Polycarboxylate Superplasticizer iguqulwe?
Uma kuqhathaniswa nochungechunge lwe-naphthalene ephezulu esebenza kahle yokunciphisa amanzi, njengokuthi, nakuba i-ejenti yokunciphisa amanzi e-poly carboxylic acid ekunciphiseni ukuwohloka kokulondoloza amanzi kunezinzuzo ezisobala ezicini zokuvikelwa kwemvelo, kodwa kunezinkinga ezithile zobuchwepheshe kuhlelo lokusebenza lobunjiniyela olusebenzayo, njengokuthi umphumela wokunciphisa amanzi wezinto zokusetshenziswa zikakhonkolo, isilinganiso sokuxuba, ukuncika komthamo we-ejenti yokunciphisa amanzi kukhulu kakhulu, ukusebenza kukakhonkolo okusha kuzwela ekusetshenzisweni kwamanzi, ukulungiswa okulula kongqimba olukhulu lokuhlukaniswa kwe-liquidity.Ukungasebenzisani kahle namanye ama-ejenti anciphisa amanzi kanye nezingxenye eziguquliwe nokuzinza komkhiqizo ompofu kukhawulela kakhulu ukusetshenziswa nokuthuthukiswa kwama-ejenti okunciphisa amanzi e-polycarboxylate.
Ukuze unqobe ukukhubazeka kwezobuchwepheshe ekusetshenzisweni kwe-ejenti yokunciphisa amanzi ye-polycarboxylate, noma ukuthuthukisa ezinye noma ezinye izakhiwo zikakhonkolo (ukusebenza, ukugcinwa kwe-slump, ukunciphisa ukopha, ukuthuthukiswa kwamandla okuqala, ukuncipha okuphansi, njll.), okudingekayo ukulungisa ukhonkolo.
Empeleni, izindlela zokuguqula ezivame ukusetshenziswa zifaka ubuchwepheshe bokwenziwa kanye nobuchwepheshe obuhlanganisiwe.Uma kuqhathaniswa nenqubo yokwenziwa, indlela ehlanganisiwe inezinzuzo zokusebenza okulula kanye nezindleko eziphansi, ngakho-ke isetshenziswa kabanzi ekusetshenzisweni okusebenzayo.Ubuchwepheshe be-Polycarboxylate series compound, i-ejenti yokunciphisa amanzi yochungechunge lwe-polycarboxylate nezinye izakhi (ezifana ne-coagulation kancane, i-defoamy, ukufakwa komoya, amandla okuqala nezinye izakhi) ngokwengxenye ethile yenhlanganisela yenhlanganisela, ukuze kuzuzwe ukubambisana ukuphakama kwengxenye ngayinye.
