1. Ukhonkolo onoketshezi oluphezulu uthambekele ekudaleni nasekuhlukaniseni.
Ezimweni eziningi, ukhonkolo olunoketshezi oluningi olulungiselelwe ngama-agent okunciphisa amanzi e-polycarboxylic acid angeke lubangele ukopha enhlanganisela yekhonkrithi ngisho noma inani le-ejenti yokunciphisa amanzi kanye nokusetshenziswa kwamanzi kulawulwa kahle, kodwa kulula kakhulu ukwenzeka. Izenzakalo zokuhlukanisa nokuhlukaniswa zibonakaliswa ekushoneni kweqoqo elimahhadla kanye nokuntanta kodaka noma udaka olumsulwa. Uma lolu hlobo lwengxube kakhonkolo lusetshenziselwa ukuthulula, i-delamination kanye nokuhlukaniswa kuyabonakala ngisho nangaphandle kokudlidliza.
Isizathu ngokuyinhloko sibangelwa ukwehla okubukhali kwe-viscosity ye-slurry lapho uketshezi lukakhonkolo oluxutshwe nale ejenti yokunciphisa amanzi esekelwe ku-polycarboxylic acid kuphezulu. Ukuhlanganiswa okulungile kwezingxenye zokuqina kungaxazulula le nkinga kuphela ngezinga elithile, futhi ukuhlanganiswa kwezingxenye eziqinisayo kuvame ukuholela ekuphenduleni kokunciphisa kakhulu umphumela wokunciphisa amanzi.
2. Uma isetshenziswe ngokuhambisana nezinye izinhlobo zama-ejenti okunciphisa amanzi, awukho umphumela obekwe phezulu.
Esikhathini esidlule, lapho ulungiselela ukhonkolo, uhlobo lwe-agent yokupompa lwalungashintshwa ngokuthanda kwakhe, futhi izakhiwo zengxube kakhonkolo zazingeke zihluke kakhulu emiphumeleni yaselabhorethri, futhi kwakungeke kube noshintsho olungazelelwe ezimpahleni zengxube kakhonkolo. .
Lapho ama-ejenti okunciphisa amanzi asuselwa ku-polycarboxylic acid esetshenziswa ngokuhlangana nezinye izinhlobo zama-ejenti anciphisa amanzi, kuba nzima ukuthola imiphumela eqinisiwe, kanye nokuncibilika phakathi kwezixazululo ze-polycarboxylic acid ezinciphisa amanzi nezinye izinhlobo zamanzi- izixazululo ze-ejenti ezinciphisayo azilungile ngokwemvelo.
3. Awukho umphumela wokuguqula ngemva kokwengeza izingxenye ezivame ukusetshenziswa ezishintshayo.
Njengamanje, kukhona ukutshalwa kwezimali okuncane ocwaningweni lwesayensi kuma-ejenti okunciphisa amanzi asuselwa ku-polycarboxylic acid. Ezimweni eziningi, inhloso yocwaningo lwesayensi iwukuqhubeka nokwenza ngcono ukusebenza kwawo kwepulasitiki nokunciphisa amanzi. Kunzima ukuklama izakhiwo zamangqamuzana ngokwezidingo zobunjiniyela ezahlukene. Uchungechunge lwama-ejenti okunciphisa amanzi asuselwe ku-polycarboxylic acid anemiphumela ehlukile yokuhlehlisa nokusheshisa, azikho izici zokungenisa umoya noma ezihlukile zokungenisa umoya, nama-viscosity ahlukene ahlanganisiwe. Ngenxa yokwehlukahlukana nokungaqini kahle kukasimende, izingxube, namaqoqo kumaphrojekthi, kubaluleke kakhulu ukuthi abakhiqizi bengxubevange nabahlinzeki bempahla bahlanganise futhi baguqule imikhiqizo yengxube ye-polycarboxylate yokunciphisa amanzi ngokwezidingo zephrojekthi.
Njengamanje, izinyathelo zobuchwepheshe zokuguqulwa kwamakhemikhali ama-ejenti okunciphisa amanzi ngokuyisisekelo zisekelwe ezinyathelweni zokuguqulwa kwama-ejenti okunciphisa amanzi endabuko njenge-lignosulfonate uchungechunge kanye nochungechunge lwe-naphthalene olusebenza kahle kakhulu lokunciphisa amanzi. Ukuhlola kufakazele ukuthi izinyathelo zobuchwepheshe zokuguqulwa ezedlule azifaneleki ngempela izinto zokunciphisa amanzi ezisuselwe ku-polycarboxylic acid. Isibonelo, phakathi kwezingxenye ezibuyiswayo ezisetshenziselwa ukuguqula ama-agent okunciphisa amanzi asekelwe ku-naphthalene, i-sodium citrate ayifaneleki kuma-agent okunciphisa amanzi asekelwe ku-polycarboxylic acid. Akukhona nje ukuthi ayinawo umphumela wokuhlehlisa, ingase isheshise i-coagulation, kanye nesisombululo se-sodium citrate I-miscibility ne-polycarboxylic acid-based-based reduction agents nayo impofu kakhulu.
Ngaphezu kwalokho, izinhlobo eziningi zama-ejenti akhipha amagwebu, ama-ejenti afaka umoya-mpilo kanye nama-thickeners azifaneleki kuma-ejenti okunciphisa amanzi ane-polycarboxylic acid. Ngokusebenzisa lezi zivivinyo nokuhlaziya okungenhla, akunzima ukubona ukuthi ngenxa yemininingwane yesakhiwo samangqamuzana e-polycarboxylic acid-based rencicing agents, ngokusekelwe ekujuleni kocwaningo lwesayensi kanye nokuqoqwa kokuhlangenwe nakho kwesicelo sobunjiniyela kulesi sigaba, umthelela. ye-polycarboxylic acid enciphisa amanzi kuma-superplasticizer asekelwe ku-polycarboxylic acid ngokusebenzisa ezinye izakhi zamakhemikhali Azikho izindlela eziningi zokushintsha ama-ejenti anciphisa amanzi, nangenxa yemibono nezindinganiso ezasungulwa esikhathini esidlule ukuze kulungiswe ezinye izinhlobo zokunciphisa amanzi. ama-ejenti, ukuhlola okujulile kanye nocwaningo kungase kudingeke kuma-ejenti okunciphisa amanzi asekelwe ku-polycarboxylate. Yenza izilungiso nokwengeza.
4. Ukuzinza kokusebenza komkhiqizo kubi kakhulu.
Azikho izinkampani eziningi zokhonkolo ezihlanganisa ama-ejenti anciphisa amanzi ezingathathwa njengezinkampani zamakhemikhali ezinhle. Izinkampani eziningi zihlala kuphela esigabeni sokuqala sokukhiqiza sezixube nemishini yokupakisha, futhi ikhwalithi yomkhiqizo inqunyelwe ikhwalithi ye-masterbatch. Mayelana nokulawulwa kokukhiqiza, ukungazinzi komthombo kanye nekhwalithi yezinto ezingavuthiwe bekulokhu kuyisici esikhulu esiphazamisa ukusebenza kwama-superplasticizer asuselwa ku-polycarboxylic acid.
