Umhla wokuThumela:5, Agasti, 2024
(一) IiNdawo zokuHlalisa
Isenzeko:Iintanda ezininzi ezimfutshane, ezithe tye, ezibanzi kunye nezingekho nzulu ziya kuvela kwikhonkrithi egalelwe phambi nasemva kokusetwa kokuqala.
Isizathu:Emva kokongeza i-agent yokunciphisa amanzi, ikhonkrithi i-viscous ngakumbi, ayifuni igazi kwaye akulula ukucwina, kwaye ibonakala kakhulu ngaphezu kweentsimbi zetsimbi.
Isisombululo: Faka uxinzelelo kwiintanda ngaphambi nangemva kokumiswa kokuqala kwekhonkrithi kude kube ukuqhekeka kuphele.
(二) Iinkonkxa eziNcangathi
Isenzeko:Inxalenye yodaka lwesamente incamathela eludongeni lomphanda womxube, ibangela ukuba ikhonkrithi ephuma kumatshini ingalingani kwaye ingabikho uthuthu.
Isizathu:Ikhonkrithi incangathi, eyenzeka kakhulu emva kokongeza ukubuyiswa komxube wokunciphisa amanzi, okanye kwizixube zemigqomo ezinomlinganiselo osondeleyo we-shaft diameter.
Isisombululo:1. Nika ingqalelo ukususa ikhonkrithi eseleyo ngexesha. 2. Okokuqala yongeza i-aggregate kunye nenxalenye yamanzi kwaye udibanise, uze udibanise i-samente, amanzi asele kunye ne-agent yokunciphisa amanzi kwaye udibanise. 3. Sebenzisa umxube onomlinganiselo omkhulu we-shaft diameter okanye umxube onyanzelekileyo
(三) Ukudibanisa okungeyonyani
Isenzeko:Ikhonkrithi ikhawuleza ilahlekelwe ngumanzi emva kokushiya umatshini kwaye ayikwazi nokugalelwa.
Isizathu:1. Ukungabikho ngokwaneleyo kwe-calcium sulfate kunye nomxholo we-gypsum kwi-samente kubangela ukuba i-calcium aluminate ikhuphe ngokukhawuleza; 2. I-ejenti yokunciphisa amanzi inokulungelelaniswa okungahambi kakuhle kolu hlobo lwesamente; 3. Xa umxholo we-triethanolamine udlula i-0.05-0.1%, ukusetwa kokuqala kuya kukhawuleza. Kodwa hayi okokugqibela.
Isisombululo:1. Guqula uhlobo lwesamente okanye inombolo yebhetshi. 2. Guqula uhlobo lwe-ejenti yokunciphisa amanzi xa kuyimfuneko, kodwa ngokuqhelekileyo akukho mfuneko. 3. Ukunciphisa izinga lokunciphisa amanzi ngesiqingatha. 4. Ukunciphisa ubushushu bokuxuba. 5. Sebenzisa i-Na2SO4 ukuhlehlisa umxholo wokumisela kwi-0.5-2%.
(四) Akukho Coagulation
Isiganeko: 1. Emva kokongeza i-agent yokunciphisa amanzi, ikhonkrithi ayizange iqiniswe ixesha elide, kwanemini yonke nobusuku; 2. Umphezulu uba ludaka kwaye ujike ube tyheli bumdaka.
Isizathu:1. I-dosage ye-ejenti yokunciphisa amanzi inkulu kakhulu, enokuthi idlule amaxesha angama-3-4 idosi ecetyiswayo; 2. Ukusetyenziswa ngokugqithisileyo kwe-retarder.
Isisombululo:1. Musa ukudlula idosi ecetyiswayo ngamaxesha angama-2-3. Nangona amandla ancitshiswe kancinci, amandla e-28d aya kuncitshiswa kancinci kwaye amandla exesha elide aya kuncitshiswa nangaphantsi. 2. Emva kokumiselwa kokugqibela, ukwandisa ukushisa okuphilisa ngokufanelekileyo kwaye uqinise ukunkcenkceshela kunye nokunyanga. 3. Susa inxalenye ebunjiweyo kwaye ugalele kwakhona.
(五) Ubunzulu obuphantsi
Isenzeko:1. Amandla aphantsi kakhulu kuneziphumo zovavanyo zexesha elifanayo; 2. Nangona ikhonkrithi iqinile, amandla ayo aphantsi kakhulu.
Isizathu:1. Ubungakanani be-agent yokunciphisa amanzi e-air-entraining bukhulu kakhulu, kubangela ukuba umxholo womoya kwikhonkrithi ube mkhulu kakhulu. 2. Ukungcangcazela okungonelanga emva kokongeza i-agent yokunciphisa amanzi e-air-entraining. 3. Amanzi awancitshiswanga okanye umlinganiselo wesamente wamanzi wandiswa endaweni yoko. 4. Isixa se-triethanolamine esongeziweyo sikhulu kakhulu. 5. Umgangatho we-arhente yokunciphisa amanzi awuhambisani neemfuno, njengomxholo wezithako ezisebenzayo ziphantsi kakhulu.
Isisombululo:1. Sebenzisa ezinye iindlela zokuqinisa okanye ukugalela kwakhona. 2. Yomeleza ukungcangcazela emva kokugalela. 3. Thatha inyathelo ngokuchasene nezi zizathu zikhankanywe ngasentla. 4. Chonga le bhetshi yemixube yokunciphisa amanzi.
(六) Ilahleko yeSlump iFass Kakhulut
Isenzeko:Ikhonkrithi iphulukana nokusebenza ngokukhawuleza okukhulu. Yonke imizuzu engama-2-3 emva kokushiya itanki, i-slump iyancipha ngo-1-2cm, kwaye kukho into ecacileyo yokutshona ezantsi. Le nto inokwenzeka ukuba yenzeke kwikhonkrithi kunye nokudilika okukhulu.
Izizathu:1. I-ejenti yokunciphisa amanzi inokulungelelaniswa okungahambi kakuhle kwi-samente esetyenzisiweyo. 2. Amaqamu omoya angeniswa kwikhonkrithi aqhubeka ephuphuma kwaye amanzi aphuphuma, ngakumbi xa usebenzisa i-air-entraining agents zokunciphisa amanzi. 3. Iqondo lokushisa lokuxuba ikhonkrithi okanye ubushushu be-ambient buphezulu; 4. Ukuwa kwekhonkrithi kukhulu.
Isisombululo:1. Thatha inyathelo ngokuchasene nonobangela. 2. Yamkela indlela yokuxuba emva kokuxuba. I-arhente yokunciphisa amanzi kufuneka yongezwe emva kokuxuba ikhonkrithi kwi-1-3 imizuzu, okanye nangaphambi kokuthulula, kwaye uvuselele kwakhona. 3. Qaphela ukuba ungagaleli amanzi.
