Hydroxypropyl Methylcellulose (HPMC) uye Hydroxyethyl Cellulose (HEC) inowanzoshandiswa mukuvaka zvinhu nekuda kwekuita kwavo kwakasiyana-siyana uye zvivakwa.Heano mamwe emabasa avo akakosha mune zvekuvaka:

1. Kuchengeta Mvura: HPMC neHEC inoshanda sevashandi vekuchengetedza mvura, zvichibatsira kudzivirira kurasikirwa kwemvura nekukurumidza kubva kune simende-yakavakirwa zvinhu zvakaita sedhaka uye plaster panguva yekurapa.Nekugadzira firimu rakatenderedza simende zvimedu, ivo vanoderedza kubuda kwemvura, zvichiita kuti hydration iwedzere uye kuvandudzwa kwesimba.
2. Kuwedzeredzwa Kwekushanda: HPMC neHEC inovandudza kushanda kwesimende-yakavakirwa zvinhu nekuwedzera mapurasitiki avo uye kuderedza kupokana pakati pezvimedu.Izvi zvinowedzera kupararira, kubatana, uye nyore kwekushandiswa kwemateki, renders, uye mataira anonamira, kufambisa akatsetseka uye mamwe mayunifomu kupera.
3. Kukora uye Rheology Kudzora: HPMC uye HEC inoshanda seyakakora uye rheology modhifita muzvivakwa zvekuvaka, kugadzirisa viscosity yavo uye kuyerera maitiro.Ivo vanobatsira kudzivirira kugadzirisa uye kupatsanurwa kwezvisanganiswa mukumiswa, kuve nechokwadi chekugovera homogeneous uye kuita kwakagadzikana.
4. Adhesion Kusimudzira: HPMC neHEC inovandudza kunamatira kwesimende-yakavakirwa zvinhu kune substrates senge kongiri, masonry, uye mataira.Nekugadzira firimu rakatetepa pamusoro pe substrate pamusoro, ivo vanosimudzira kusimba kwechisungo uye kusimba kwedhaka, renders, uye mataira anonamira, kuderedza njodzi yedelamination kana kutadza.
5. Shrinkage Reduction: HPMC neHEC inobatsira kuderedza kuderera uye kuputika mune simende-based zvinhu nekuvandudza kugadzikana kwavo kwemukati uye kuderedza kushushikana kwemukati.Ivo vanozadzisa izvi nekusimudzira particle kurongedza, kuderedza kurasikirwa kwemvura, uye kudzora mwero we hydration, zvichikonzera kupera kwakasimba uye kunakidza kunofadza.
6. Kuisa Nguva Yekudzora: HPMC neHEC inogona kushandiswa kugadzirisa nguva yekumisikidza yesimende-yakavakirwa zvinhu nekugadzirisa dosage yavo uye molecular uremu.Ivo vanopa kuchinjika mukurongeka kwekuvaka uye vanobvumira kudzora kurinani pamusoro pekugadzirisa maitiro, kugonesa akasiyana mapurojekiti zvinodiwa uye mamiriro ezvakatipoteredza.
7. Yakavandudzwa Kusimba: HPMC neHEC inobatsira kusimba kwenguva refu kwezvinhu zvekuvakisa nekusimudzira kuramba kwavo kune zvakatipoteredza zvinhu zvakaita sechando-thaw kutenderera, hunyoro ingress, uye kurwisa kwemakemikari.Ivo vanobatsira kudzikisira kutsemuka, spalling, uye kuparara, kurebesa hupenyu hwebasa rezvirongwa zvekuvaka.

Hydroxypropyl Methylcellulose (HPMC) uye Hydroxyethyl Cellulose (HEC) vanoita mabasa akakosha mukusimudzira mashandiro, kushanda, kunamatira, kusimba, uye huwandu hwese hwezvinhu zvekuvaka.Zvinhu zvavo zvakasiyana-siyana zvinoita kuti zvive zvakakosha zvekuwedzera mune zvakasiyana-siyana zvekuvaka, kuve nechokwadi chekubudirira uye hupenyu hurefu hwezvirongwa zvakasiyana-siyana zvekuvaka.
