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 ne-polyvinyl acetate namanye ama-polymers ancibilika emanzini).
Izici ze-starch ether ikakhulukazi zimi kulokhu:
(1) Thuthukisa ukumelana ne-sag;
(2) Ukuthuthukisa ukwakheka;
(3) Isivuno esiphezulu sodaka.
Uyini umsebenzi oyinhloko we-starch ether odakeni olomile olususelwa ku-gypsum?
I-starch ether ingenye yezithako eziyinhloko zodaka lwempushana eyomile. Ingahambisana nezinye izithasiselo. Isetshenziswa kabanzi kuma-adhesive tile, ukulungisa ama-mortars, i-gypsum plastering, i-putty yangaphakathi nengaphandle yodonga, i-gypsum-based caulking and filling materials, ama-interface agents, amatshe emasikeni, ifaneleka futhi ifakwe ngesandla noma isifutho nge-cement-based noma i-gypsum. -izinsimbi ezisekelwe. Isebenza kanje:
(1) I-starch ether ivamise ukusetshenziswa kuhlanganiswe ne-methyl cellulose ether, okubonisa umphumela omuhle wokusebenzisana phakathi kwakho kokubili. Ukwengeza inani elifanelekile le-starch ether ku-methyl cellulose ether kungathuthukisa ngokuphawulekayo ukumelana nokushelela kanye nokumelana nokushelela kodaka , ngenani lesivuno esiphezulu.
(2) Ukwengeza inani elifanele le-starch ether odakeni oluqukethe i-methyl cellulose ether kungakhuphula ngokuphawulekayo ukuhambisana kodaka, kuthuthukise ukugeleza kwamanzi, futhi kwenze ukwakhiwa kushelele futhi kushelele.
(3) Ukwengeza inani elifanelekile le-starch ether odakeni oluqukethe i-methyl cellulose ether kungakhuphula ukugcinwa kwamanzi odaka futhi kwandise isikhathi sokuvula.
Yiziphi izinzuzo zokusetshenziswa nezindlela zokugcina isitashi ether?
Ingasetshenziswa njengengxube yemikhiqizo esekwe usimende, imikhiqizo esekwe ku-gypsum kanye nemikhiqizo ye-ash-calcium.
(1) Izinzuzo nezicelo:
a. Inomphumela wokujiya odakeni, ingajiya ngokushesha, futhi ibe nokuthambisa okuhle;
b. Isilinganiso sincane, futhi umthamo ophansi kakhulu ungafinyelela umphumela ophezulu;
c. Thuthukisa ikhono lokulwa nesilayidi lodaka oluboshiwe;
d. ukwandisa isikhathi esivulekile sezinto ezibonakalayo;
e. Thuthukisa ukusebenza kokusebenza kwento futhi wenze ukusebenza kube bushelelezi.
(2) Isitoreji:
Umkhiqizo ungenwa kalula ngumswakama futhi kufanele ugcinwe endaweni eyomile nepholile ephaketheni lokuqala. Kungcono ukuyisebenzisa phakathi nezinyanga eziyi-12. (Kunconywa ukuthi kusetshenziswe ngokuhambisana ne-high-viscosity cellulose ether, kanye nesilinganiso esijwayelekile se-cellulose ether ne-starch ether ngu-7:3~8:2)
