3. Kuchengeta Mvura:

Rimwe remabasa ekutanga eHPMC kuchengetedza mvura mukati memusanganiswa weputty.
Ichi chivakwa chinogonesa kurebesa hydration ye simenti masisitimu, inosimudzira kurapa kurinani uye yakagadziridzwa kubatana kune substrate.

4. Kuvandudzwa Kwekushanda:

HPMCinopa kushanda kwakanakisa kumadziro putty, zvichiita kuti zvive nyore kuisa uye kupararira zvakaenzana pane dzakasiyana nzvimbo.
Iyo inosimudzira kutsetseka uye kuenderana kweiyo putty, ichibvumira isina musono application uye kupedzisa.

Nekudzikisa kuumbwa kwekutsemuka uye kutsemuka, inobatsira kuhupenyu hurefu uye kukwezva kwekunaka kwenzvimbo yakapendwa.

7. Kuenderana neZviwedzerwa:

HPMC inowirirana neakasiyana-siyana ekuwedzera anowanzo shandiswa mumadziro putty maumbirwo, akadai dispersants, defoamers, uye preservatives.
Uku kugarisana kunobvumira kuchinjika mukugadzira putties akagadzirirwa kune chaiwo maitiro ekuita.

8. Mafungiro Ezvakatipoteredza uye Utano:

HPMC inoonekwa seine hushamwari uye yakachengeteka kushandiswa mukuvaka zvinhu.
Haisi muchetura, isingatsamwise, uye inoora, ichiisa njodzi shoma kuhutano hwevanhu kana nharaunda.

9. Mitemo yekushandisa:

Iyo dosage yeHPMC mumadziro putty formulations inowanzobva pa 0.1% kusvika 0.5% nehuremu hwesimende.
Kupararira kwakakodzera uye kusanganisa kwakakosha kuti uve nechokwadi chekugovera yunifomu yeHPMC mukati memusanganiswa weputty.

10. Kuvimbiswa Kwehutano:

Vagadziri vemadziro putty vanowanzoomerera kune zvemhando yepamusoro uye zvakatemwa kuti ive nechokwadi chekushanda uye kuenderana kwezvigadzirwa zvavo.
HPMC inoshandiswa mumadziro putty formulations inofanirwa kusangana neakakodzera indasitiri zviyero uye kuongororwa kwakasimba kwekuita uye kuvimbiswa kwemhando.

Hydroxypropyl methylcellulose (HPMC)chinhu chinodiwa chekuwedzera mumadziro putty maumbirwo, chinopa zviuru zvezvibatsiro zvinosanganisira kuvandudzwa kwekushanda, kunamatira, kuchengetedza mvura, uye kuramba kuparara. Kusarudzika kwayo uye kuenderana nezvimwe zvinowedzera zvinoita kuti ive sarudzo inosarudzika yekusimudzira mashandiro uye kusimba kwemadziro putties mukuvaka maapplication.
