Sei HPMC Inoshandiswa muDry Mortar?

Hydroxypropyl Methylcellulose (HPMC) inowanzoshandiswa mukugadzirwa kwedhaka rakaoma nekuda kwemaitiro ayo akasiyana anosimudzira kushanda uye kushanda kwedhaka. Heino chikonzero nei HPMC ichishandiswa mudhaka rakaoma:

1. Kuchengeta Mvura:

HPMC inoshanda sechinhu chekuchengetedza mvura mudhaka yakaoma maumbirwo, ichibatsira kuchengetedza hunyoro hwemukati mukati mekusanganisa, kushandisa, uye kurapa maitiro. Iyi yakareba hydration inovandudza kushanda, kunamatira, uye kusimba kwechisungo chedhaka, zvichiita kuti uite zvirinani uye kusimba.

2. Kuvandudzwa Kwekushanda:

HPMC inovandudza kushanda uye kuenderana kwedhaka rakaoma nekusimudzira rheological properties. Inopa dhaka rakatsetseka uye rakanyorovera, zvichiita kuti zvive nyore kusanganisa, kuparadzira, nekuisa. Izvi zvinovandudza maitiro ekubata kwedhaka uye inovimbisa kuvhara yunifomu uye kunamatira kune substrates.

3. Yakaderedzwa Kudonha uye Kudonha:

HPMC inobatsira kudzikisira kudonha uye kudonha mune yakatwasuka uye pamusoro pekushandisa kwedhaka rakaoma. Iyo inovandudza thixotropic zvimiro zvedhaka, ichiibvumira kuchengetedza chimiro chayo uye kugadzikana pane yakatwasuka nzvimbo pasina sagging kana kumhanya. Izvi zvinogonesa yunifomu ukobvu uye kufukidzwa kwedhaka layer.

4. Enhanced Adhesion:

HPMC inovandudza kunamatira uye kubatanidza simba redhaka rakaoma kune akasiyana substrates sekongiri, masonry, huni, uye ceramics. Inoshanda sebhainda uye firimu-inogadzira mumiriri, inosimudzira hukama pakati pedhaka ne substrate. Izvi zvinowedzera kushanda uye kusimba kweiyo dhaka system, kuderedza njodzi ye delamination uye kutadza.

5. Crack Resistance:

HPMC inobatsira kuvandudza kuramba kwekupwanyika uye kuvimbika kwechimiro chekuoma kwedhaka maumbirwo. Iyo inosimudzira kubatana uye kuchinjika kwedhaka, kuderedza mukana wekuputsika kutsemuka uye kuremara kwepamusoro panguva yekurapa uye hupenyu hwebasa. Izvi zvinoita kuti pave nenzvimbo dzakapfava, dzakasimba dzinochengetedza kuvimbika kwavo pasi pemamiriro ekunze akasiyana.

6. Kugarisana:

HPMC inowirirana nehuwandu hwakawanda hwezvimwe zvinowedzera zvinowanzo shandiswa mukuoma dhaka maumbirwo, senge simende, jecha, mafirita, uye admixtures. Inogona kuiswa nyore nyore mumatope ekugadzira kuti uwane inodiwa maitiro ekuita pasina kukanganisa zvimwe zvivakwa kana mashandiro.

7. Regulatory Compliance:

HPMC inosangana nemirairo yemitemo uye zvinodiwa zvezvinhu zvekuvaka, kuve nechokwadi chekuteedzera makodhi ekuvaka nemirau. Inoita kuyedzwa kwakasimba uye chitupa kuvimbisa kuchengetedzwa, mhando, uye kuita mukuoma kwedhaka zvikumbiro.

Muchidimbu, Hydroxypropyl Methylcellulose (HPMC) inoshandiswa mukuumbwa kwedhaka rakaoma kuvandudza kuchengetwa kwemvura, kushanda, sag resistance, adhesion, crack resistance, uye kuenderana. Hunhu hwayo hwakasiyana hunoita kuti ive yekuwedzera yakakosha pakugadzirisa mashandiro, kusimba, uye kushanda kweaoma dhaka masisitimu mumashandisirwo akasiyana ekuvaka.
