Hpmc inokanganisa sei nguva yekuisa yemasimendi-yakavakirwa?

HydroxyPropyl methylcellose (HPMC) ndiyo kiyi yekuwedzera inoshandiswa mune yemasimendi-yakavakirwa zvinhu kudzora zvivakwa zvakasiyana, kusanganisira kugara nguva. Kunzwisisa kuti HpMC inokanganisa sei nguva inoda nguva inoda kubviswa mune zvimiro zvemakemikari, zvekudyidzana nezvinhu zvemisangano, uye michina inokanganisa maitiro ekugadzirisa.

1.Tobroduction kune HPMC mune yeComent-based zvigadzirwa

HPMC iri cellulose ether inowana nehydroxypruppropyl uye mapoka mapoka. Zvinowanzoitwa mukuvaka semumiriri wekuchengetedza mvura, thickener, uye rheology modifier. Muzvinyorwa zveSement-based, HPMC inoshumira zvinangwa zvakawanda, kusanganisira kusimudzira kugona, kuvandudza kuderera, uye kudzora nguva yekugara.

2.chemical kutaurirana nekement

Pakusangana nezvinhu zvemasero, HPMC inopararira mumvura inogadzira viscous coolution mhinduro. Iyo hydrophic chimiro cheHPMC inofambisa kuchengetwa kwemvura, iyo inoshamba kuwanikwa kwemvura yeiyo siment hydration. Iyi nzira yakasimba hydration yakakosha pakuzadzisa simba raunoda uye kusimba.

HPMC mamorekuru anofambidzana nezvikamu zve simende kuburikidza neHydrogen kusungwa uye magetsi masimba emauto. Izvi zvinobatanidzwa zvinoshandura hunhu hwepamusoro hwekusimbisa zvidimbu, zvichikanganisa kupararira kwavo uye hydration kinetics. Nekuda kweizvozvo, HPMC inogona kukurudzira nhumbi uye kukura kwe hydrate, pakupedzisira inokanganisa nguva yekugara.

3.Frants pane kugara nguva

Iyo nguva yekuisa yeiyo yemasimende-yakavakirwa inoreva nguva inodiwa kuti isanganiswa kuti ishandurwe kubva papurasitiki, yakashanda mamiriro kune yakaomeswa, nyika yakasimba. HPMC inogona kukurudzira zvakanyanya maitiro aya kuburikidza neminda yakati wandei:
Kuchengeta kwemvura: HPMC kugona kwemvura kuchengeta mvura kunobata kuwanikwa kwekunyorova kweiyo coment hydration. Iyi yakashongedzwa hydration inogona kuwedzera nguva yekuisa nekuona kuenderera mberi kwemakemikari maitiro pakati pekement nemvura.
Rheological shanduko: HPMC inokwazisa zvivakwa zvezvinyorwa zvemisangano yemasangano, ichipesvedzera kuyerera kwavo newiscosity. Kudzora viscosity kwakakosha kwekushanda uye kugara nguva. Yakakwira viscosity inononoka kusimbisa kweiyo simenti zvidimbu uye kuderedza maitiro ekugadzirisa.
Hydration Kinetics: HPMC inokanganisa huwandu hwenzvimbo yeiyo hydration nekugadzirisa iyo nzvimbo yemukati yeiyo coment zvidimbu uye kudzora kuwanikwa kwemvura. Nekudzora iyo nhandare ye hydrate, HPMC inogona kukurumidza kuendesa kana kuyananisa nguva yekuisa zvinoenderana nemushonga uye chairo chimiro.
Kudzoserwa maitiro: Mune zvimwe zviitiko, HPMC zviito sekudzoreredza nekugadzira chipinganidzo chekudzivirira kutenderera coment zvidimbu, zvichitadzisa kuwana mamorekuru emvura anodiwa kuti hydration. Uku kunonoka mu hydration kunotambanudzira nguva yekugara, kupa nguva yakawanda yekuiswa uye kupedzisa kongiri kana dhiri.
DOSAGE uye SEPLASE SIZE: Iyo mhedzisiro yeHPMC pane yekumisikidza nguva ndeye DOSAGE-Inotsvaga. Kuvatarira kwakakwirira kunowanzowedzera nguva yekugara, nepo yakadzika makomendi inogona kuve nemhedzisiro midiki kana kutowedzera kuisa mamiriro ezvinhu pasi pemamwe mamiriro ezvinhu. Pamusoro pezvo, saizi yehukuru hweHPMC inogona kukanganisa kupararira kwayo uye kushanda, nekudaro kukanganisa nguva.

4.Petimization uye kutonga

Kuzadzisa iyo nguva yaunoda yekuisa inoda kunyatsoongorora yeHPMC Dosage, chidimbu chevhu, uye mafomu emahara. Mainjiniya uye makondirakiti anofanirwa kufunga nezvezvinhu zvakasiyana-siyana senge ambient tembiricha, humidity, simende mhando, uye zvinodiwa projekiti kana uchisarudza uye uchiramba hpmc zvinowedzera.

Kuedzwa kuchikurukurirana kwakakosha kuti uve nechokwadi chekuti HPMC haina kukanganisa zvimwe zvinhu zvezvivakwa zvemasimende, zvakadai sekusimudzira simba, kudzikira, kana kusimba. Yakakodzera mhando dzekudzora matanho anodiwa kuti urambe uchikosheswa uye kuita mumagariro akasiyana uye mashandisirwo.

HydroxyPropyl methylcellose (HPMC) inoita basa rakakosha mukudzora nguva yekurongedza nzvimbo yekuchengetwa kwemvura, Kunzwisisa kuunganidzwa pakati peHPMC uye simende kwakakosha kwekufungidzira kusanganisa kwemagetsi uye kuzadzisa zvaunoda maitiro ekuita mune zvekuvaka. Nekunyatsogadzirisa HPMC Dosage uye mainjiniya uye mainjiniya uye makondirakiti anogona kubata zvinobudirira kugara kwenguva apo kusimbisa kushandira, kusimba, uye kusimba kwemisangano yemasimendi.
