Njira yogwiritsira ntchito starch ether mumatope

Starch ether ndi mtundu wa cellulose ether yomwe imagwiritsidwa ntchito ngati chowonjezera mumatope kuti igwire bwino ntchito.Ntchito yayikulu ya wowuma ether mumatope ndikukulitsa magwiridwe antchito ake, kusunga madzi, komanso kumamatira.Njira yogwiritsira ntchito starch ether mumatope ikhoza kufotokozedwa motere:

1. Kupititsa patsogolo ntchito: Wowuma ether amatha kukonza magwiridwe antchito a matope pochepetsa kukhuthala kwa kusakaniza.Izi zimatheka ndi adsorption wa wowuma etere mamolekyu pamwamba pa particles simenti, amene amachepetsa awo amalipiritsa electrostatic ndi kumawonjezera kuyenda.Izi zimachepetsa kukangana pakati pa particles, kuwalola kuti azisuntha momasuka komanso mosavuta.Zotsatira zake, matope amakhala ochulukirapo komanso osavuta kugwira nawo ntchito.
2. Kusungirako madzi: Wowuma ether amatha kukonza kusungirako madzi mumatope popanga filimu yoteteza kuzungulira tinthu ta simenti.Filimuyi imalepheretsa madzi osakaniza kuti asatuluke mofulumira, zomwe zimapangitsa kuti matope azikhala ogwiritsidwa ntchito kwa nthawi yaitali.Izi ndizofunikira makamaka pakatentha ndi kouma, komwe madzi amatuluka mumatope amakhala okwera kwambiri.
3. Kumamatira: Wowuma ether amatha kupititsa patsogolo kumamatira kwa matope ku gawo lapansi powonjezera kulimba kwake.Izi zimatheka ndi mapangidwe zomangira haidrojeni pakati pa wowuma etere mamolekyulu ndi gawo lapansi pamwamba, amene kumawonjezera interfacial adhesion mphamvu.Izi zimakulitsa mphamvu yolumikizana pakati pa matope ndi gawo lapansi, kuchepetsa chiopsezo cha kutayika kapena kulephera.

Mwachidule, zochita limagwirira wa wowuma ether mu matope zachokera mphamvu kumapangitsanso workability, madzi posungira, ndi katundu adhesion wa osakaniza.Wowuma ether amakwaniritsa izi mwa kuchepetsa kukhuthala kwa kusakaniza, kupanga filimu yoteteza kuzungulira tinthu ta simenti, ndikuwonjezera mphamvu ya matope.Kugwiritsiridwa ntchito kwa wowuma ether mumatope kumatha kupititsa patsogolo ntchito yonse ndi kukhazikika kwa osakaniza, zomwe zimapangitsa kuti pakhale njira yomanga yogwira ntchito komanso yogwira mtima.
