Kushandiswa kweStarch Ether muSimende-Yakavakirwa Zvigadzirwa

Starch ether imhando yeHydroxypropyl starch ether iyo inoshandiswa zvakanyanya sekuwedzera muzvigadzirwa-samende zvakaita sedhaka, kongiri, uye grouts.Basa guru re starch ether mune izvi zvigadzirwa nderekuvandudza kushanda kwavo, kuchengetedza mvura, uye kunamatira zvinhu.Kushandiswa kwestarch ether muzvigadzirwa-samende zvinogona kutsanangurwa sezvinotevera:

1. Kuwedzeredzwa kwekushanda: Starch ether inogona kuvandudza kushanda kwesemende-based zvigadzirwa nekuderedza viscosity yavo.Izvi zvinowanikwa nekuyeredzwa kwemamorekuru estarch ether pamusoro pemasimende, izvo zvinodzikisira machaji emagetsi uye kuwedzera kufamba kwavo.Izvi zvinobvumira simenti kuti ifambe zvakasununguka, zvichiita kuti mvura iwedzere uye nyore kushanda nemusanganiswa.
2. Kuchengetwa kwemvura: Starch ether inogona kuvandudza kuchengetwa kwemvura yezvigadzirwa-samende nekugadzira firimu rinodzivirira rakatenderedza masimende.Iyi firimu inodzivirira mvura yemusanganiswa kuti irege kubuda nekukurumidza, zvichibvumira simenti-based product kuti irambe ichishanda kwenguva yakareba.Izvi zvinonyanya kukosha mumamiriro ekupisa uye akaoma, apo chiyero chekubuda kwemvura kubva kune simenti-based product yakakwirira.
3. Adhesion: Starch ether inogona kuvandudza kunamatira kwesement-based zvigadzirwa kune substrate nekuwedzera tackiness yavo.Izvi zvinowanikwa nekuumbwa kwehydrogen zvisungo pakati pe starch ether molecules uye substrate pamusoro, iyo inowedzera interfacial adhesion simba.Izvi zvinovandudza simba rose rekubatanidza pakati pesimende-yakavakirwa chigadzirwa uye substrate, kuderedza njodzi yekusungwa kana kutadza.
4. Crack resistance: Starch ether inogonawo kuvandudza kutsemuka kwezvigadzirwa zvesimende nekuwedzera simba ravo rekusimba.Izvi zvinowanikwa kuburikidza nekuumbwa kwetatu-dimensional network ye starch ether molecules mumusanganiswa, iyo inoshanda sekusimudzira uye inobatsira kugovera kushushikana kwesimba zvakanyanya.Izvi zvinogona kuvandudza kusimba kwese uye hupenyu hurefu hwesimende-yakavakirwa chigadzirwa.

Muchidimbu, kushandiswa kwe starch ether mune simende-based zvigadzirwa zvinogona kuvandudza kushanda kwavo, kuchengetedza mvura, kunamatira, uye crack resistance properties.Starch ether inozadzisa izvi nekuderedza viscosity yemusanganiswa, kuumba firimu rinodzivirira rakakomberedza masimende, kuwedzera tackiness yemusanganiswa, uye kuwedzera simba rekusimba rechigadzirwa.Kushandiswa kwe starch ether mune sement-based products kunogona kuvandudza kushanda kwese uye kusimba kwemusanganiswa, zvichiita kuti pave nekugadzirisa uye kushanda kwekuvaka.
