Dry mix mortar
Dry mix mortar inoreva musanganiswa wepre-mixed wefine aggregate, simende nezvinowedzerwa zvinongoda kuwedzerwa nemvura panzvimbo yekuvaka.Iri dhaka rinofarirwa zvakanyanya nekureruka kwekushandisa, kuenderana mhando, uye kukwidziridzwa kuita zvichienzaniswa neyechinyakare pa-saiti yakasanganiswa madhaka.
Hydroxypropylmethylcellulose (HPMC)
HPMC isiri-ionic cellulose ether inotorwa kubva kune yakasikwa polymer cellulose.Inoshandiswa zvakanyanya mukuvaka, mishonga, chikafu uye mamwe maindasitiri.Mune yakaoma-musanganiswa dhaka, HPMC chinhu chakakosha chekuwedzera chinobata ese maficha emarara maitiro uye kuita.
Basa reHPMC mune yakaoma yakasanganiswa dhaka
1. Kuchengeta mvura
HPMC inogona kukwidziridza kuchengetwa kwemvura kweyakaoma-musanganiswa dhaka uye kudzivirira kurasikirwa nekukurumidza kwemvura.Izvi zvinonyanya kukosha panguva yekuvaka nekurapa, sezvo kuchengetwa kwemvura yakakwana kunovimbisa hydration yakakodzera ye simenti, nekudaro inovandudza kukura kwesimba uye kusimba.
2. Kukora
Seyakakora, HPMC inobatsira kuvandudza kuenderana uye kushanda kweiyo yakaoma-musanganiswa dhaka.Inobatsira kudzivirira dhaka kubva pakudonha uye kutsvedza panguva yakatwasuka maapplication akadai sekupurasita kana kugadzirisa mataira.
3. Kuvandudza kunamatira
HPMC inogona kuvandudza zvivakwa zvekubatanidza zvedhaka rakaoma rakasanganiswa uye kukurudzira zvirinani kubatana pakati pedhaka uye akasiyana substrates.Izvi zvakakosha pakuita kwenguva refu uye kugadzikana kwedhaka rinoshandiswa.
4. Isa nguva yekudzora
Nekupesvedzera nguva yekumisikidza yedhaka, HPMC inopa kutonga kukuru pamusoro pemaitiro ekuvaka.Izvi zvinonyanya kukosha mumapurojekiti ekuvaka, sezvo zvikumbiro zvakasiyana zvinoda nguva yakatarwa.
5. Kuramba kusagika uye kuputika
Kuwedzera HPMC kunobatsira kudzivirira yakaoma musanganiswa dhaka kubva pakudonha uye kutsemuka.Izvi zvinonyanya kubatsira mumashandisirwo akamira apo dhaka inoda kunamatira kumusoro pasina kudonha kana kuputika panguva yekurapa.
6. Mhedzisiro pane rheology
HPMC inoshandura rheological zvimiro zveyakaoma-musanganiswa dhaka, inokanganisa kuyerera kwayo maitiro uye viscosity.Izvi zvinogonesa kuti dhaka rinogona kuiswa uye kupararira zviri nyore uchichengetedza ukobvu hunodiwa uye kuenderana.
Mabhenefiti ekushandisa HPMC mune yakaoma musanganiswa dhaka
1. Kusachinja-chinja uye kubatana
HPMC inobatsira kuchengetedza kunaka kwekuoma-musanganiswa dhaka, kuve nechokwadi chekufanana kwezvinhu zvakadai sekushanda, kunamatira uye kuchengetedza mvura.Izvi zvakakosha kuti uwane mhedzisiro inovimbika uye inofanotaurwa mumashandisirwo ekuvaka.
2. Wedzera maawa ekuvhura
Nguva yakavhurika yedhaka ndiyo nguva iyo dhaka rinoramba richishandiswa mushure mekusanganiswa.HPMC inowedzera nguva yakavhurika, inopa shanduko panguva yekuvaka, uye inoderedza mukana wekuoma nguva isati yakwana.
3. Wedzera kusimba
Iyo yekuchengeta mvura uye yekunamatira zvivakwa zvakapihwa neHPMC zvinobatsira kuvandudza kusimba kweakaoma musanganiswa dhaka.Maumbirwo ematope achishandisa HPMC haanyanyi kutarisana nezvinetso zvakadai sekuputika, izvo zvinogona kukanganisa kutendeseka kwenguva refu kwechimiro.
4. Kushanda zvakasiyana-siyana
HPMC inowirirana nemhando dzakasiyana dzemaumbirwo edhaka, zvichiita kuti ive yekuwedzera yakawanda kune akasiyana siyana ekuvaka ekushandisa.Inogona kusanganiswa nezvimwe zvekuwedzera kuti uwane chaiyo yekuita zvinodiwa.
Kushandiswa kweHPMC mune yakaoma yakasanganiswa dhaka
1. Kupura dhaka
Mukupura matope, HPMC inodzivirira kudonha uye inonatsiridza kunamatira kune substrate, ichibatsira kuwana yakatsetseka, kunyange pamusoro.
2. Tile inonamira
HPMC inowanzoshandiswa mumatairi anonamira maumbirwo ekusimudzira kunamatira, kuchengetwa kwemvura uye sag kuramba, kuve nechokwadi chisungo chakavimbika pakati petaira ne substrate.
3. Masonry dhaka
Mumasonry madhaka, HPMC inobatsira kuvandudza mashandiro ekuvaka uye kusimba, zvichikonzera kushanda, kunogara kwenguva refu madziro uye kuvaka kwemaitiro.
4. Dongo rekuzvimisa
Zvekuzvimisikidza dhaka zvikumbiro, HPMC inobatsira kudzora mafambiro ekuyerera, kudzivirira kupatsanurwa uye kuve nechokwadi chenzvimbo yakatsetseka.
5. Gadzirisa dhaka
Mukugadzirisa zvigadziriso zvevhu, HPMC inobatsira kuwana chisungo chakasimba pakati pekugadzirisa zvinhu uye substrate iripo, nekudaro inovandudza kushanda kwese kwekugadzirisa kwakagadziriswa.
mukupedzisa
Muchidimbu, hydroxypropyl methylcellulose (HPMC) inoita basa rakasiyana-siyana uye rinokosha mukuumbwa kwevhu rakaoma-musanganiswa.Kukanganisa kwayo pakuchengetedza mvura, kunamatira, rheology uye zvimwe zvakakosha zvimiro zvinokanganisa zvakanyanya kuita kwese uye kunaka kwedhaka.Sezvo indasitiri yekuvaka ichiramba ichishanduka, HPMC inoramba ichiwedzera yakakosha, ichigonesa kuvandudzwa kwepamusoro, yakavimbika yakaoma musanganiswa wedhaka maumbirwo emhando dzakasiyana dzekushandisa.
