Starch ether inonyanya kushandiswa mukuvaka dhaka, iyo inogona kukanganisa kuenderana kwedhaka rakavakirwa gypsum, simende uye lime, uye kushandura kuvaka uye sag kuramba kwedhaka.Starch ethers inowanzoshandiswa pamwe chete neasina-modified uye modified cellulose ethers.Inokodzera ese ari maviri asina kwaakarerekera uye alkaline masisitimu, uye inoenderana neakawanda ekuwedzera mune gypsum uye simende zvigadzirwa (senge masurfactants, MC, starch uye polyvinyl acetate uye mamwe mapolymer anonyungudika nemvura).
Main features:
(1) Starch ether inowanzoshandiswa pamwe chete nemethyl cellulose ether, iyo inoratidza yakanaka synergistic effect pakati pezviviri.Kuwedzera huwandu hwakakodzera hwe starch ether kune methyl cellulose ether inogona kuvandudza zvakanyanya sag resistance uye kutsvedza kuramba kwedhaka, ine goho rakakura.
(2) Kuwedzera huwandu hwakakodzera hwe starch ether kune dhaka rine methyl cellulose ether inogona kuwedzera zvakanyanya kuwirirana kwedhaka uye kugadzirisa mvura, zvichiita kuti chivakwa chive chakapfava uye kukwenya kupfava.
(3) Kuwedzera huwandu hwakakodzera hwe starch ether kudhaka rine methyl cellulose ether kunogona kuwedzera kuchengetwa kwemvura kwedhaka uye kuwedzera nguva yakazaruka.
(4) Starch ether ikemikari yakagadziridzwa starch ether inonyungudika mumvura, inoenderana nezvimwe zvinowedzera muvhu rakaoma dhaka, rinoshandiswa zvakanyanya mukunamira mataira, kugadzirisa dhaka, plaster plaster, mukati nekunze kwemadziro putty, gypsum-based embedded Joints uye zvinhu zvekuzadza. , interface agents, masonry dhaka.
Hunhu hwe starch ether hunonyanya kuve mu: (a) kunatsiridza sag resistance;(b) kunatsiridza kushanda;(c) kuvandudza mwero wekuchengetedza mvura yedhaka.
Range rekushandisa:
Starch ether inokodzera marudzi ese e (simende, gypsum, lime-calcium) mukati uye kunze kwemadziro putty, uye marudzi ese ekutarisana nedhaka uye plastering dhaka.
Inogona kushandiswa semusanganiswa wesimende-based zvigadzirwa, gypsum-based zvigadzirwa uye lime-calcium zvigadzirwa.Starch ether ine kuenderana kwakanaka nemamwe mavakirwo uye admixtures;inonyanya kukodzera pakuvaka misanganiswa yakaoma sedhaka, zvinonamira, plastering uye rolling zvinhu.Starch ethers uye methyl cellulose ethers (Tylose MC mamakisi) anoshandiswa pamwechete mukuvaka misanganiswa yakaoma kupa kukora kwepamusoro, chimiro chakasimba, sag kuramba uye nyore kubata.Iko viscosity yematope, zvinonamira, plasters uye roll renders ine yakakwirira methyl cellulose ethers inogona kuderedzwa nekuwedzera kwe starch ethers.
