Starch ether Gadzirisa dhaka, wedzera sag resistance, sag resistance uye rheology yedhaka
Semuenzaniso, pakuvaka tile glue, putty, uye plastering dhaka, kunyanya ikozvino kuti kupfapfaidza kwemuchina kunoda mvura zhinji, semuenzaniso, inonyanya kukosha mudhaka-based gypsum (muchina wakapfapfaidzwa plaster unoda kuyerera kwakanyanya asi kukonzeresa kwakakomba chiitiko. , starch Ether inogona kugadzirisa kukanganisa uku).
Liquidity uye sag kuramba zvinowanzopokana, uye kuwedzera kwemvura kunounza kuderera kwekusaga kuramba. Iyo dhaka ine rheological properties inogona kunyatsogadzirisa kupokana kuti kana simba rekunze rikaiswa, viscosity inoderera, iyo inowedzera kushanda uye kupomba, uye kana simba rekunze rabviswa, viscosity inowedzera uye inovandudza sag kuramba.
Nekuda kwemaitiro azvino ekuwedzera mataira nzvimbo, kuwedzera starch ether kunogona kuvandudza kutsvedza kupikisa kwekunamatira mataira.
2) Wedzera maawa ekuvhura
Zvekunamira mataira, zvinogona kusangana nezvinodiwa zvematairi akasarudzika ane nguva yakawedzerwa yakavhurika (Kirasi E, wedzera kubva 20min kusvika 30min kusvika 0.5MPa).
a. Surface performance kunatsiridza
Starch ether inogona kuita pamusoro pegypsum-based uye simende dhaka yakatsetseka, nyore kuisa, uye ine yakanaka yekushongedza maitiro. Izvo zvakakosha zvikuru kune plaster-based mortars uye yakatetepa-layer yekushongedza dhaka senge putty.
b. Iyo nzira yekuita kwe starch ether
Kana starch ether yakanyungudutswa mumvura, inoparadzirwa zvakaenzana musimende mortar system. Nekuti starch ether molecules ine network yakarongeka uye inopomerwa zvisina kunaka, ivo vanozoshambadza zvakanaka chaja simende zvimedu, izvo zvinogona kushandiswa sebhiriji rekuchinja kubatanidza simende, nokudaro kupa Iyo yakakura kukosha kwegoho re slurry inogona kuvandudza anti-sagging kana. anti-slip effect.
