Starch etherinonyanya kushandiswa mukuvaka dhaka, iyo inogona kukanganisa kuenderana kwedhaka rakavakirwa gypsum, simende uye lime, uye kuchinja 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 surfactants, MC, starch uye mvura-soluble polymers akadai polyvinyl acetate).
Basa guru
(1) Yakanaka inokurumidza kukora kugona: yepakati viscosity, kuchengetwa kwemvura yakakwirira;
(2) Muyero wacho idiki, uye muyero wakaderera unogona kuita zvakanaka;
(3) Kuvandudza iyo anti-sag kugona kwezvinhu pachayo;
(4) Iine lubricity yakanaka, iyo inogona kuvandudza mashandiro echigadzirwa uye kuita kuti kuvhiya kuve nyore.
Main features
Hunhu hwe starch ether hunonyanya kuve mu:
(a) Kuvandudza sag resistance;
(b) Kuvandudza kuvakwa;
(c) Kuvandudza mwero wekuchengetedza mvura yedhaka.
Synergy
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 kuramba uye kutsvedza kuramba kwedhaka. Kukosha kwegoho repamusoro.
Mudhaka rine methyl cellulose ether, kuwedzera chiyero chakakodzera che starch ether inogona kuwedzera zvakanyanya kuenderana kwedhaka uye kugadzirisa fluidity, zvichiita kuti chivakwa chive chakapfava uye kukwesha.
Mudhaka rine methyl cellulose ether, kuwedzera huwandu hwakakodzera hwe starch ether kunogona kuwedzera kuchengetwa kwemvura kwedhaka uye kuwedzera nguva yakazaruka.
Starch ether ikemikari yakagadziridzwa starch ether inonyungudika mumvura, inoenderana nezvimwe zvinowedzera mune yakaoma poda dhaka, inoshandiswa zvakanyanya mumatairi anonamira, kugadzirisa dhaka, plaster plaster, mukati uye kunze kwemadziro emadziro, gypsum-based caulking uye kuzadza Zvishandiso, interface agents, dhaka remasonry.
Starch ether inokodzera marudzi ese e (simende, gypsum, lime calcium-based) mukati uye kunze kwemadziro putty, nemhando dzakasiyana dzekutarisana nedhaka plastering dhaka.
Inogona kushandiswa semusanganiswa wesimende-based zvigadzirwa, gypsum-based zvigadzirwa uye lime-calcium zvigadzirwa. Starch ether ine kuenderana kwakanaka nemamwe mavakirwo uye admixtures; inokodzera kuvaka musanganiswa wakaoma sedhaka, zvinonamira, plastering uye rolling zvinhu. Starch ether uye methyl cellulose ether (KimaCellMC giredhi) anoshandiswa pamwechete mukuvaka akaomeswa musanganiswa kuti ape yakakwira gobvu, yakasimba chimiro, sag kuramba uye nyore kubata. Iko viscosity yematope, zvinonamira, plasters uye roll renders ine yakakwirira methyl cellulose ethers inogona kuderedzwa nekuwedzera kwe starch ethers.
