The action mechanism ye starch ether mudhaka

Starch ether imhando ye cellulose ether iyo inowanzoshandiswa sechinhu chinowedzera mudhaka kuti ivandudze kushanda kwayo.Basa guru re starch ether mudhaka nderekuwedzera kushanda kwayo, kuchengetedza mvura, uye adhesion properties.Maitiro ekuita kwe starch ether mudhaka anogona kutsanangurwa sezvinotevera:

1. Kuwedzera kwekushanda: Starch ether inogona kuvandudza kushanda kwedhaka nekuderedza viscosity yemusanganiswa.Izvi zvinowanikwa nekuyeredzwa kwemamorekuru estarch ether pamusoro pemasimende, izvo zvinodzikisira machaji emagetsi uye kuwedzera kufamba kwavo.Izvi zvinoderedza kukakavara pakati pezvimedu, zvichiita kuti zvifambe zvakasununguka uye zviri nyore.Somugumisiro, dhaka rinowedzera mvura uye nyore kushanda naro.
2. Kuchengetedzwa kwemvura: Starch ether inogona kuvandudza kuchengetwa kwemvura kwedhaka nekugadzira firimu rinodzivirira rakatenderedza masimende.Iyi firimu inodzivirira mvura mumusanganiswa kuti irege kubuda nekukurumidza, zvichiita kuti dhaka rirambe richishanda kwenguva yakareba.Izvi zvinonyanya kukosha mumamiriro ekupisa uye akaoma, apo kuputika kwemvura kubva mumatope kwakakwirira.
3. Adhesion: Starch ether inogona kuvandudza kunamatira kwedhaka kune substrate nekuwedzera tackiness yayo.Izvi zvinowanikwa nekuumbwa kwehydrogen zvisungo pakati pe starch ether molecules uye substrate pamusoro, iyo inowedzera interfacial adhesion simba.Izvi zvinovandudza simba rose rekubatanidza pakati pedhaka uye substrate, kuderedza dambudziko rekuvhara kana kukundikana.

Muchidimbu, maitiro ekuita kwe starch ether mudhaka inobva pakukwanisa kwayo kuwedzera kushanda, kuchengetedza mvura, uye kunamatira zvimiro zvemusanganiswa.Starch ether inozadzisa izvi nekudzikisa viscosity yemusanganiswa, kugadzira firimu rinodzivirira rakatenderedza masimende masimende, uye kuwedzera tackiness yedhaka.Kushandiswa kwe starch ether mudhaka kunogona kuvandudza kushanda kwese uye kusimba kwemusanganiswa, zvichiita kuti pave nekugadzirisa uye kushanda kwekuvaka.
