Starch ether ishoko rakajairwa kukirasi yeakagadziridzwa masita ane ether zvisungo mumorekuru, inozivikanwawo se etherified starch, iyo inoshandiswa zvakanyanya mumishonga, chikafu, machira, kugadzira mapepa, makemikari ezuva nezuva, peturu uye mamwe maindasitiri.Nhasi isu tinonyanya kutsanangura basa re starch ether mudhaka:
1) Gadzirisa dhaka, wedzera anti-sagging, anti-sagging uye rheological zvimiro zvedhaka.
Semuyenzaniso, mukuvaka mataira anonamira, putty, uye plastering dhaka, kunyanya iko zvino iko iko iko kupfapfaidza kwemuchina kunoda kuyerera kwakanyanya, senge mudhaka-based gypsum, inonyanya kukosha (muchina-sprayed gypsum inoda yakakwira fluidity asi ichizokonzeresa kusaga. , starch Ether inogona kugadzirisa kushayikwa uku).Ndiko kuti, kana simba rekunze rikaiswa, viscosity inodzikira, ichiwedzera kushanda uye kupomba, uye kana simba rekunze rabviswa, viscosity inowedzera, ichivandudza kusagirira kuramba.Nekuda kwemaitiro azvino ekuwedzera mataira nzvimbo, kuwedzera starch ether kunogona kuvandudza kutsvedza kupikisa kwekunamatira mataira.
2) Kuwedzerwa maawa ekuvhura
Kune mataira anonamira, anogona kusangana nezvinodiwa zveakakosha mataira adhesives (Kirasi E, 20min yakawedzera kusvika 30min kusvika 0.5MPa) iyo inowedzera nguva yekuvhura.Starch ether inogona kuita pamusoro pegypsum base uye simende dhaka kutsvedzerera, nyore kuisa, uye ine yakanaka yekushongedza maitiro.Izvo zvine zvazvinoreva kupurasita dhaka uye nhete yekushongedza dhaka senge putty.
1. Starch ether inogona kunyatsovandudza anti-sag uye anti-slip properties yedhaka
Cellulose ether kazhinji inogona kungovandudza viscosity uye kuchengetwa kwemvura kwegadziriro asi haigone kuvandudza anti-sagging uye anti-slip properties.
2. Kukora uye viscosity
Kazhinji, viscosity ye cellulose ether inenge makumi ezviuru, nepo viscosity ye starch ether inosvika mazana akawanda kusvika kuzviuru zvakati wandei, asi izvi hazvirevi kuti kukora kwepfuma ye starch ether kudhaka haina kunaka seye cellulose ether, uye nzira yekukora yezviviri izvi zvakasiyana.
3. Anti-slip performance
Kuenzaniswa ne cellulose ethers, starch ethers inogona kuwedzera zvakanyanya kukosha kwekutanga kwegoho rematairi adhesives, nekudaro kuvandudza avo anti-slip properties.
4. Air-entraining
Cellulose ether ine mhepo yakasimba-inopinza midziyo, nepo starch ether isina mhepo-inopinza midziyo.
