ISINCISHISI SAMANZI ESIPHEZULU (SMF)iyi-medium kagesi ye-anion encibilika emanzini ene-polymer ephezulu. I-SMF inomuncu oqinile kanye nomphumela ophansi kusimende. I-SMF ingenye yezindawo zokusika amanzi ezisetshenziswa ekhonkrithini ekhona. Izici eziyinhloko yilezi: umhlophe, izinga eliphezulu lokunciphisa amanzi, uhlobo lokungenisa umoya olungenawo umoya, okuqukethwe kwe-chloride ion ephansi akugqwali ezingodweni zensimbi, kanye nokuzivumelanisa kahle ne-simende ehlukahlukene. Ngemva kokusebenzisa i-ejenti yokunciphisa amanzi, ukuqina kokuqala kanye nokugeleza kwekhonkrithi kwanda kakhulu, izakhiwo zokwakha kanye nokugcinwa kwamanzi kwaba ngcono, futhi ukulungiswa komusi kwaguqulwa.
Uma ukhonkolo ubhidlika, isimo esifanayo singanciphisa kakhulu ukuxubana kwamanzi okubizwa ngokuthi i-ejenti yokunciphisa amanzi esebenza kahle kakhulu. Uma kwenzeka okufanayo, ubhidlika, ukuxubana kanye nokusetshenziswa kwamanzi kungancishiswa ngamaphesenti angaphezu kuka-15.
Intuthuko umlando:Isizukulwane sokuqala se-ejenti yokunciphisa amanzi esebenza kahle kakhulu kanye ne-superplasticizer esekelwe ku-amine resin yasungulwa ekuqaleni kwawo-1960. Ngenxa yokusebenza kwe-ejenti yokunciphisa amanzi evamile yi-lignesulfonate eyasungulwa ngasekupheleni kwawo-1930, yaziwa nangokuthi i-superplasticizer. I-ejenti yokunciphisa amanzi esebenza kahle kakhulu yesizukulwane sesibili yi-amino sulfonate, yize ngokulandelana kwayo ngemva kwesizukulwane sesithathu se-superplasticizer - uchungechunge lwe-polycarboxylic acid. I-graft copolymer ene-sulfonic acid kanye ne-carboxylic acid ibaluleke kakhulu esizukulwaneni sesithathu se-ejenti yokunciphisa amanzi esebenza kahle kakhulu, futhi ukusebenza kwayo futhi kuyi-ejenti yokunciphisa amanzi esebenza kahle kakhulu.
Izinhlobo eziyinhloko:Izinga lokunciphisa amanzi le-ejenti yokunciphisa amanzi esebenza kahle kakhulu lingafinyelela ngaphezu kuka-20%. Ngokuyinhloko uchungechunge lwe-naphthalene, uchungechunge lwe-melamine kanye ne-ejenti yokunciphisa amanzi eyakhiwe yizo, phakathi kwazo uchungechunge lwe-naphthalene oluyinhloko, olubalelwa ku-67%. Ikakhulukazi, iningi lama-ejenti okunciphisa amanzi esebenza kahle kakhulu lisekelwe ku-naphthalene njengezinto zokusetshenziswa eziyinhloko. Ngokusho kokuqukethwe kwe-Na2SO4 ku-superplasticizer yochungechunge lwe-naphthalene, ingahlukaniswa ibe yimikhiqizo yokuhlushwa okuphezulu (okuqukethwe kwe-Na2SO4 < 3%), imikhiqizo yokuhlushwa okuphakathi (okuqukethwe kwe-Na2SO4 3%-10%) kanye nemikhiqizo yokuhlushwa okuphansi (okuqukethwe kwe-Na2SO4 > 10%). Izitshalo eziningi zokwenziwa kwe-naphthalene superplasticizer zinamandla okulawula okuqukethwe kwe-Na2SO4 ngaphansi kuka-3%, futhi amanye amabhizinisi athuthukile angalawula ngisho nokuqukethwe kwe-NA2SO4 ngaphansi kuka-0.4%.
Uchungechunge lwe-Naphthalene lwe-ejenti yokunciphisa amanzi luyiyona enkulu kunazo zonke ekukhiqizweni kwezwe lethu, i-ejenti yokunciphisa amanzi esebenza kahle kakhulu esetshenziswa kakhulu (ebala ngaphezu kuka-70% wenani le-ejenti yokunciphisa amanzi), ebonakala ngesilinganiso sokunciphisa amanzi esiphezulu (15% ~ 25%), ukungabikho komoya, umthelela omncane esikhathini sokubeka, ukuzivumelanisa nezimo okuhle kakhulu ne-simende, ingasetshenziswa nezinye izithako ezahlukahlukene, intengo nayo ishibhile. I-Naphthalene superplasticizer ivame ukusetshenziselwa ukulungisa ukhonkolo ngokuhamba okuphezulu, amandla aphezulu kanye nokusebenza okuphezulu. Ukulahleka kokhonkolo okuwohlokayo nge-naphthalene superplasticizer kuyashesha. Ngaphezu kwalokho, ukuzivumelanisa nezimo kwe-ejenti yokunciphisa amanzi yochungechunge lwe-naphthalene kanye ne-simende ethile kudinga ukuthuthukiswa.
Izakhiwo:I-ejenti yokunciphisa amanzi esebenza kahle kakhulu inomphumela oqinile wokusabalala kusimende, ingathuthukisa kakhulu ukugeleza kwengxube yesimende kanye nokuwa kwekhonkrithi, kuyilapho inciphisa kakhulu ukusetshenziswa kwamanzi, ithuthukise kakhulu ukusebenza kahle kwekhonkrithi. Kodwa i-superplasticizer ethile izosheshisa ukulahlekelwa yikhonkrithi, ukuxuba kakhulu kuzokhipha amanzi. I-ejenti yokunciphisa amanzi esebenza kahle kakhulu ayishintshi isikhathi sokusetha ukhonkrithi, futhi inomphumela wokulibazisa kancane lapho umthamo mkhulu (ukufakwa komthamo ngokweqile), kodwa ayilibazisi ukukhula kwamandla okuqala kwekhonkrithi eqinile.
Kunganciphisa kakhulu ukusetshenziswa kwamanzi futhi kuthuthukise kakhulu amandla ekhonkrithi eminyakeni ehlukene. Uma amandla ehlala engaguquki, i-simende ingagcinwa ngo-10% noma ngaphezulu.
Okuqukethwe kwe-chloride ion kuncane, akukho mphumela wokugqwala ebharini lensimbi. Kungathuthukisa ukungenwa kwamanzi, ukumelana nokuqandisa kanye nokumelana nokugqwala kwekhonkrithi, futhi kuthuthukise ukuqina kwekhonkrithi.
ISICELO:
1, Kufanelekela zonke izinhlobo zokwakha zezimboni nezomphakathi, ukongiwa kwamanzi, ezokuthutha, ichweba, ukwakheka kwangaphambili kobunjiniyela bomasipala kanye nokhonkolo oluqinisiwe olufakwe endaweni.
2, Kufanelekela ukhonkolo onamandla aphezulu, onamandla aphezulu kakhulu kanye namandla aphakathi, kanye nezidingo zamandla okuqala, ukumelana nesithwathwa okulingene, ukhonkolo omkhulu woketshezi.
3, Kufanelekela amalungu ekhonkrithi alungisiwe kusengaphambili enqubo yokupholisa umusi.
4, Ifanelekela izinhlobo ezahlukene zenhlanganisela yezingxenye zokuqinisa ezinciphisa amanzi (i-Master Batch).
