HEMC FOR Dry Mixed Mortars

Mune yakaoma musanganiswa dhaka, Hydroxyethyl Methylcellulose (HEMC) inoshanda seyakakosha yekuwedzera inopa dzakasiyana siyana dzinoshanda zvivakwa zvinosimudzira kuita kwedhaka musanganiswa. Dry mix mortars pre-musanganiswa maumbirwo anoshandiswa mukuvaka kwekushandisa senge mataira anonamira, renderings, plasters, uye grouts. Heano maitiro HEMC inobatsira kune yakaoma musanganiswa dhaka:

1. Kuchengetedzwa Kwemvura: HEMC ine yakanakisa yekuchengetedza mvura zvivakwa, izvo zvakakosha mumisanganiswa yakaoma madhaka. Inobatsira kuchengetedza mvura mukati memusanganiswa wedhaka, kudzivirira kuoma nguva isati yakwana uye kuve nechokwadi chekuti hydration yakakwana yezvinhu zvecementitious. Ichi chivakwa chinovandudza kushanda, chinorebesa nguva yakavhurika, uye inosimudzira kunamatira kune substrates.
2. Kukora uye Rheology Kudzora: HEMC inoshanda seyakakora uye rheology modifier, ichipesvedzera kuenderana uye kuyerera maitiro emusanganiswa wevhu. Nekugadzirisa iyo viscosity uye rheological zvivakwa, HEMC inofambisa zvirinani maitiro ekushandisa, akadai sekuvandudza kupararira, kuderera kuderera, uye kuwedzera kubatana.
3. Kuvandudzwa Kwekushanda: Kuvepo kweHEMC kunowedzera kushanda kwemavhu akaoma musanganiswa, zvichiita kuti zvive nyore kusanganisa, kuisa, uye kubata. Iyo inosimudzira zvirinani trowelability, ichibvumira kune yakatsetseka uye yakawanda yunifomu application panzvimbo. Izvi zvinoguma nekuvandudzwa kwepamusoro kupedzisa uye yakazara aesthetics.
4. Yakaderedzwa Shrinkage uye Kutsemuka: HEMC inobatsira kuderedza shrinkage uye kuputika mumisanganiswa yakaoma madhaka nekuvandudza homogeneity yemusanganiswa uye kuderedza mvura evaporation mazinga. Izvi zvinobatsira pakugara kwenguva refu uye kuvimbika kwechimiro chedhaka rakaiswa.
5. Enhanced Adhesion: HEMC inonatsiridza kunamatira kweakaoma musanganiswa dhaka kune akasiyana substrates, kusanganisira kongiri, masonry, uye ceramic mataira. Inoumba chisungo chakasimba pakati pedhaka uye substrate, zvichiita kuti zvive nani kunamatira zvinhu uye kuwedzera simba rezvisungo.
6. Kuenderana Nezvimwe Zviwedzerwa: HEMC inopindirana nehuwandu hwakawanda hwezvimwe zvinowedzera zvinowanzoshandiswa mukuoma musanganiswa wevhu, zvakadai semhepo-entraining agents, plasticizers, uye kuseta accelerators. Izvi zvinobvumira kugadzirwa kuchinjika uye kugadzirisa kuti isangane nezvakada kuita zvinodiwa.

HEMC inoita basa rakakosha mukugadzirisa mashandiro ematokari akaomarara nekuvandudza kushanda, kunamatira, kuchengetwa kwemvura, uye huwandu hwese. Kushandiswa kwayo kunobatsira kuve nechokwadi chekubudirira uye kwakanyatso kuisirwa kwezvinhu zvakasiyana-siyana zvekuvaka uku uchichengetedza kuwirirana uye kusimba mumashandisirwo apera.
