Starch ether. Kodza dhaka, wedzera kuramba kudonha, kuramba kudonha uye rheology yedhaka.
Semuenzaniso, pakugadzira glue yemataira, putty, uye plastering mortar, kunyanya ikozvino sezvo kupfapfaidza kwemuchina kuchida kuyerera kwakawanda, semuenzaniso, zvakakosha zvikuru mu gypsum-based mortar (plaster inopfapfaidzwa nemuchina inoda kuyerera kwakawanda asi inokonzera kusadzika kwakanyanya, starch Ether inogona kutsiva kukanganisa uku).
Kuramba kwemvura uye kusakara kunowanzopesana, uye kuwedzera kwekuyerera kwemvura kunounza kudzikira kwekuramba kusakara. Mota ine hunhu hwerheological inogona kugadzirisa kusawirirana kwekuti kana simba rekunze rikashandiswa, viscosity inoderera, izvo zvinowedzera kushanda uye kupomba, uye kana simba rekunze rikabviswa, viscosity inowedzera uye inovandudza kusakara.
Panyaya yekuwedzera nzvimbo yemataira pari zvino, kuwedzera starch ether kunogona kuwedzera kuramba kwe tile glue.
2) Wedzera maawa ekuvhura
Kune zvinonamira mataira, zvinogona kusangana nezvinodiwa zvezvinonamira mataira zvakakosha zvine nguva yakareba yekuvhura (Kirasi E, inotangira pamaminitsi makumi maviri kusvika makumi matatu kusvika pamaminitsi 0.5MPa).
a. Kuvandudza mashandiro epamusoro
Starch ether inogona kuita kuti pamusoro pedhaka rakagadzirwa negypsum nesimende pave pakanaka, nyore kuisa, uye ine mhedzisiro yakanaka yekushongedza. Inokosha zvikuru kumadhaka akagadzirwa neplaster uye madhaka ekushongedza akatetepa akadai seputty.
b. Maitiro ekuita kwe starch ether
Kana starch ether yanyungudutswa mumvura, inopararira zvakaenzana musystem yesimbi yesimbi. Nekuti mamorekuru esimbi yesimbi ane chimiro che network uye ane negative charge, anosveta positive charged siment particles, izvo zvinogona kushandiswa se transition bridge yekubatanidza simende, nokudaro zvichipa goho rakakura re slurry rinogona kuvandudza anti-sagging kana anti-slip effect.
