Cellulosesziya ngokuya zisetshenziswa ezintweni ezisuselwa kusika kasimende, ikakhulukazi odongeni olomile, ngenxa yokugcinwa kwawo kwamanzi okuhle nemiphumela yokuqina. Ngakho-ke, izakhiwo kanye nendlela yokwenzaI-Cellulose Ether izinto ezisuselwa kuso usimende olungiselelwe kanye nokuxhumana phakathiI-Cellulose Ether Futhi kancane uCement Slurry ube nzima kancane ukunakwa emikhakheni yezinto zokwakha kanye nobunjiniyela eminyakeni yamuva. Imiphumela eminingi yocwaningo iye yafinyelelwa. Ukuhlanganisa inqubekela phambili yocwaningo ekhaya nakwamanye amazwe, kusekhona izinkinga ezilandelayo ocwaningweni nasekusetshenzisweni kweI-Cellulose Ether Izinto zokwenziwa ngokomusi oguquliwe:
1.Kukhona izinhlobo eziningi zecelluloses.-Lingeneyocelluloses Kusetshenziswe ezintweni ezisetshenziswayo zikasimende zihlukaniswe ngezinhlobo eziningi ezinjenge-HEC, i-hemc ne-HPMC ngenxa yezinga lazo. Uhlobo olufanayo lwecellulosesube nomehluko omkhulu ekwakhekeni kwamangqamuzana, isisindo samangqamuzana, izinga lokufaka esikhundleni noma okuqukethwe okungaphezulu. Njengamanje, ucwaningo oluningi ekhaya nakwamanye amazwe lugxile koyedwa noma oluninganacelluloses.Ukukhethwa kwecellulose ethenr kukhawulelwe emikhakheni yazo yohlelo lokusebenza. Isimo sesakhiwo samangqamuzana secelluloses azikhonjimanga, futhi ukumelwa kwazo akumeleli. Isiphetho umphumela ongenakugwemeka 'wokufakwa esikhundleni ngokwengxenye ", futhi kukhona ukuphikisana kanye nezimpikiswano phakathi kwemiphumela yokuhlolwa. Ngakho-ke, kuyadingeka ukutadisha ngokuhlelekile ukwahlukaniswa kanye nezinqubo zezinhlobo ezahlukahlukene zeI-Cellulose Ether izinto eziguquliwe eziguquliwe.
2.Exing Iteren Ifuze Umthelela Wecelluloses Ezakhiweni ezahlukahlukene zezinto zokwakha i-cementional, futhi kwenziwa ukuhlaziya okuthile kwendlela yalo yokwakha, kepha kwehlulekile ukuthola ubudlelwano phakathi kwesakhiwo samangqamuzanacelluloses kanye nezakhiwo ze-slurry kasimende eguquliwe. Ukuvama, futhi kunomehluko osobala ezimweni zabo. Phakathi kwa-I-Cellulose EtherIzinto zokwenziwa usimende osuselwa kumasimende, kunezifundo ezimbalwa ezintweni ezinezinto ezahlukene zesakhiwo zamangqamuzana, ezingakwazi ukuchaza indlela yokwakha yezakhiwo ezahlukahlukene zeI-Cellulose EtherIzinto zokwenziwa zikasimende ezifakiwe. . Yize ezinye izincwadi zithola lokhocelluloses Ngezinhlaka ezahlukahlukene zamangqamuzana zinemiphumela ehlukene ku-hydration ka usimende, izizathu ezingaphansi zingakaze ziphinde zanda.
3.Indlela yethonya leI-Cellulose Ether Ku-Cement Hydration Kinetics kusaqhubeka nokufunda. Njengamanje, maqondana nendlela ebambezelekile ye-hydration yeI-Cellulose Ether, yize i-adsorption ibhekwa njengembangela yangempela ye-hydration ebambezelekile yeI-Cellulose Ether, kutholakala ukuthi amandla aqine amandla aphakathi kwemikhiqizo ye-hydration futhiI-Cellulose Ether, i-hydration ebambezelekile kakhudlwana kasimende. Indlela ye-adsorption phakathicelluloses kanye nemikhiqizo ye-Cement Hydration, kanye nezizathu zamakhono ahlukile we-adsorption ahlukilecelluloses kanye nemikhiqizo ye-Cement Hydration, ayikaze ifundwe.
4.exing izincwadi kukhombisa lokhocelluloses kungathinta kakhulu ukwakheka kwe-pore kwezinto zokwenziwa kosimende.Celluloses Kukholakala ukuthi usebenza ngokusebenza okuphezulu futhi ube nomphumela ongenisa umoya kuma-slurries amasha, ngaleyo ndlela wanda i-porolity ye-slurries elukhuni. Kodwa-ke, ithonya lecelluloses Esikhathini esijwayelekile kanye nendlela yokwakhiwa kukaCement Slurry usayizi kasayizi wokusatshalaliswa akukaze kuxoxwe ngakho.
I-5. Izakhiwo ze-Rheological ziyisici esibalulekile sokusetshenziswa kwecelluloses ezintweni ezisuselwa kusika. Ngeshwa, kunezifundo ezimbalwa ezakhiweni zeRheological zeI-Cellulose Ether I-Slurry eguquliwe ekhaya nakwamanye amazwe.
