Iiarhente zokunciphisa amanzi zidla ngokuba zii-anionic surfactants, kwaye ngoku zisetyenziswa ngokuqhelekileyo kwimarike ziquka i-polycarboxylic acid based rencing agents, i-naphthalene based rencing agents, njl. , ukuphucula amandla ekhonkrithi, kunye nokunciphisa ukuvela kweentanda. Badlala indima ebalulekileyo ekulawuleni ukusebenza kwekhonkrithi. Nangona kunjalo, imixube yekhonkrithi exutywe neearhente zokunciphisa amanzi zinokudibana neengxaki ezinjengokuncamathela kwitanki kunye nokusetwa kobuxoki. Ukuze ugweme ukwenzeka kweengxaki ezahlukeneyo, uFreeman uya kuhlalutya izizathu kunye nezisombululo zeengxaki nganye nganye.

一. Inokunamathela isenzeko:
I-Phenomenon: Inxalenye yodaka lwesamente ibambelela eludongeni lwesilinda somxube, ibangela ukukhutshwa okungalinganiyo kunye nokuncinci kothuthu lwekhonkrithi, okukhokelela kwikhonkrithi encangathi.
Uhlalutyo lwesizathu:
Ukuncamathelwa kwekhonkrithi kaninzi kwenzeka emva kokongeza iiretarders kunye neearhente zokunciphisa amanzi, okanye kwimixube yedrum enomlinganiselo ofanayo we-axial diameter.
Imigaqo yohlaziyo:
(1) Ukunyamekela ngexesha lokucoca kunye nokususa ikhonkrithi eseleyo;
(2) Okokuqala, yongeza ii-aggregates kunye namanzi ukuze udibanise, emva koko wongeze isamente, amanzi ashiyekileyo, kunye ne-agent yokunciphisa amanzi ukuze udibanise;
(3) Sebenzisa i-shaft diameter enkulu okanye umxubi onyanzelweyo.

二.Pseudo coagulation phenomenon
I-Phenomenon: Ikhonkrithi emva kokushiya umatshini ngokukhawuleza ilahlekelwa yi-fluidity yayo kwaye ayikwazi ukugalelwa.
Uhlalutyo lwesizathu:
(1) Ukungabikho ngokwaneleyo kwe-calcium sulfate kunye ne-gypsum kwi-samente kukhokelela ekugqithiseni ngokukhawuleza kwe-calcium aluminate;
(2) I-ejenti yokunciphisa amanzi ayinakukwazi ukuziqhelanisa nolu hlobo lwesamente;
(3) Xa umxholo we-triethanolamine udlula i-0.05-0.1%, ukusetwa kokuqala kukhawuleza kodwa kungabikho kokugqibela.
Imigaqo yohlaziyo:
(1) Ukutshintsha uhlobo lwesamente;
(2) Ukuba kuyimfuneko, lungisa i-admixtures kwaye wenze ukudibanisa okufanelekileyo;
(3) Yongeza inxalenye ye-Na2SO4 kwi-admixture.
(4) Ukunciphisa ubushushu bokuxuba
