Isitashi etherisetshenziswa kakhulu ekwakheni udaka, okungase kuthinte ukungaguquguquki kodaka olusekelwe ku-gypsum, usimende kanye nomcako, futhi kushintshe ukwakhiwa nokumelana nodaka lodaka.Ama-ether esitashi ngokuvamile asetshenziswa ngokuhambisana nama-cellulose ether angashintshiwe futhi ashintshiwe.Ilungele kokubili izinhlelo ezingathathi hlangothi kanye ne-alkaline, futhi ihambisana nezithasiselo eziningi ze-gypsum kanye nemikhiqizo kasimende (njengama-surfactants, i-MC, isitashi nama-polymers ancibilika emanzini njenge-polyvinyl acetate).
Umsebenzi oyinhloko
(1) Ikhono elihle lokujiya ngokushesha: i-viscosity ephakathi, ukugcinwa kwamanzi okuphezulu;
(2) Umthamo mncane, futhi umthamo ophansi ungaba nomphumela omuhle;
(3) Thuthukisa amandla e-anti-sag wento ngokwayo;
(4) Ine-lubricity enhle, engathuthukisa ukusebenza kwempahla futhi yenze umsebenzi ube bushelelezi.
Main izici
Izici ze-starch ether ikakhulukazi zimi kulokhu:
(a) Thuthukisa ukumelana ne-sag;
(b) Ukwenza ngcono ukwakhiwa;
(c) Ukwenza ngcono izinga lokugcinwa kwamanzi odaka.
I-Synergy
I-starch ether ivamise ukusetshenziswa kanye ne-methyl cellulose ether, ebonisa umphumela omuhle wokusebenzisana phakathi kwalokhu kokubili.Ukwengeza inani elifanelekile le-starch ether ku-methyl cellulose ether kungathuthukisa kakhulu ukumelana nokushelela kanye nokumelana nokushelela kodaka.Inani lesivuno esiphezulu.
Odakeni oluqukethe i-methyl cellulose ether, ukwengeza inani elifanele le-starch ether kungakhuphula ngokuphawulekayo ukuvumelana kodaka futhi kuthuthukise ukugeleza kwamanzi, okwenza ukwakhiwa kube bushelelezi futhi ukukhuhla kube bushelelezi.
Odakeni oluqukethe i-methyl cellulose ether, ukwengeza inani elifanele le-starch ether kungakhuphula ukugcinwa kwamanzi odaka futhi kwandise isikhathi esivulekile.
I-starch ether iyi-ether yesitashi eguqulwe ngamakhemikhali encibilika emanzini, ehambisana nezinye izithasiselo odakeni lwempushana eyomile, esetshenziswa kakhulu ezintweni ezinamathelayo zamathayela, udaka lokulungisa, ukhonkolo olukhonkolo, i-putty yodonga lwangaphakathi nangaphandle, i-gypsum-based caulking and filling Materials, ama-interface agents, udaka lwamatshe.
I-starch ether ilungele zonke izinhlobo (usimende, i-gypsum, i-lime calcium-based) i-putty yangaphakathi nengaphandle yodonga, kanye nezinhlobo ezahlukene zodaka olunamekwe olubhekene nodaka.
Ingasetshenziswa njengengxube yemikhiqizo esekwe usimende, imikhiqizo esekwe kwigypsum kanye nemikhiqizo ye-lime-calcium.I-starch ether inokuhambisana okuhle nokunye ukwakhiwa kanye nezingxube;ilungele ukwakhiwa kwezingxube ezomile ezifana nodaka, izinto zokunamathisela, ukuplasta kanye nezinto zokugingqa.Isitashi ether ne-methyl cellulose ether (KimaCellMC grade) zisetshenziswa ndawonye ekwakheni izingxube ezomile ukuze zinikeze ukujiya okuphezulu, ukwakheka okuqinile, ukumelana ne-sag kanye nokubamba kalula.I-viscosity yodaka, izinto ezinamathelayo, amaplasta kanye nama-roll renders aqukethe i-methyl cellulose ether ephezulu ingancishiswa ngokufakwa kwe-starch ether.
