Drymix mortars chinhu chakakosha mukuvaka kwemazuva ano, zvichiita kuti zvive nyore, zvakavimbika, uye zvienderane.Hydroxypropyl Methylcellulose(HPMC) chinhu chakakosha chinowedzera basa guru mukusimudzira mashandiro uye hunhu hwemamota edrymix. Gwaro iri rakazara rinoongorora basa reHPMC mumamota edrymix, kusanganisira chimiro chayo chemakemikari, hunhu hwayo, uye mabhenefiti ayo mukushandiswa kwakasiyana-siyana.
2. Chii chinonzi Hydroxypropyl Methylcellulose (HPMC)?
2.1. Maumbirwo emakemikari
HPMC ipolymer inogadzirwa ne semi-synthetic inobva mu cellulose. Inogadzirwa kuburikidza nekushandurwa kwe cellulose ne propylene oxide ne methyl chloride. Mugumisiro wacho i cellulose ether ine hydroxypropyl ne methoxy groups dzakabatana ne cellulose backbone. Dhigirii rekutsiva (DS) remapoka aya rinogona kusiyana, zvichikonzera magiredhi akasiyana e HPMC.
2.2. Zvivakwa
HPMC ine zvinhu zvakakosha zvinoita kuti ikodzere kushandiswa mumamortars e drymix:
- Kunyungudika kwemvura: HPMC inonyungudika mumvura, zvichiita mhinduro yakasimba uye yakajeka.
- Kuchengetwa kwemvura: Ine simba rakakura rekuchengetedza mvura, zvichiita kuti zvidimbu zvesimende zvirambe zvichinyoroveswa nguva dzose.
- Kugadzira firimu: HPMC inogona kugadzira firimu rakatetepa, rinochinjika pamusoro pezvidimbu zvemortar, zvichiwedzera kunamira.
- Kugadziriswa kweRheology: Kunokanganisa kuyerera uye kushanda zvakanaka kwemamortar.
- Kudzora Kuisa: HPMC inogona kuwedzera kana kudzora nguva yekuisa madhaka.
3. Basa reHPMC muDrymix Mortars
3.1. Kuchengetwa kweMvura
Rimwe remabasa makuru eHPMC mumadhaka emusanganiswa wemvura ndeyekuchengetedza mvura. Inodzivirira kurasikirwa nemvura nekukurumidza kubva mumusanganiswa wedhaka, zvichiita kuti pave nehunyoro hwakakwana hwemvura yesimbi yesimbi. Hunhu uhwu hunokosha zvikuru mumamiriro ekupisa uye akaoma, uko kuoma nguva isati yakwana kunogona kutungamira pakusimba uye kunamira kushoma.
3.2. Kushanda Kwakavandudzwa
HPMC inowedzera kushanda kwemamota nekuchinja hunhu hwawo hwe rheological. Inoshanda sechinhu chinosimbisa kukora, zvichiita kuti kuyerera kwemvura kuve nani uye kudzikira kwekudzikama. Izvi zvinoita kuti zvive nyore kushandisa uye kupera kwacho kuve kwakapfava mukushandisa senge plaster ne self-leveling mortars.
