Hydroxypropyl Methyl Cellulose (HPMC) i polymer inoshanda zvakasiyana-siyana inowana mashandisirwo akawandisa mumhando dzakasiyana dzekuvaka nekuda kweiyo yakasarudzika zvivakwa.Iyi cellulose ether derivative inotorwa kubva kune yakasikwa cellulose uye inoshandiswa zvakanyanya muzvigadzirwa zvekuvaka kuitira kuchengetedza kwayo mvura, kukora, uye kusunga kwayo.
1. Nhanganyaya yeHydroxypropyl Methyl Cellulose (HPMC)
Hydroxypropyl Methyl Cellulose is non-ionic cellulose ether inowanikwa nekurapa natural cellulose nepropylene oxide uye methyl chloride.Inonyungudika mumvura uye inoumba yakajeka, viscous solution.Hunhu hwakasiyana-siyana hweHPMC hunobva mukukwanisa kwayo kugadzirisa rheological zvivakwa, kuchengetwa kwemvura, uye kunamatira mune zvekuvaka.
2. Zvikumbiro muMortar
2.1.Kuchengeta Mvura
HPMC inowanzoshandiswa mukugadzira dhaka kuwedzera kuchengetwa kwemvura.Yayo hydrophilic chimiro inobvumira kuti itore uye ichengetedze mvura, ichidzivirira kuoma kusati kwasvika kwedhaka.Ichi chivakwa chinovimbisa kushanda kuri nani, nguva yakareba yekuisa, uye yakagadziridzwa kunamatira kune substrates.
2.2.Kukora uye Rheology Kudzora
Kuwedzerwa kweHPMC mumatope maumbirwo kunopa inodiwa thickening zvivakwa, zvichipesvedzera rheological maitiro emusanganiswa.Izvi zvakakosha kuti zvive nyore kushandisa uye kuwana kuenderana kunodiwa mudhaka.
2.3.Yakavandudzwa Adhesion
Kubatanidza HPMC mudhaka kunosimudzira kunamatira kune akasiyana mativi, zvichibatsira kune iyo yakazara simba uye kusimba kwechinhu chekuvakisa.Izvi zvinonyanya kukosha mumashandisirwo akadai sekuisa mataira eceramic.
3. Zvikumbiro muTile Adhesives uye Grouts
3.1.Enhanced Workability
Mataira anonamira kazhinji ane HPMC yekuvandudza kushanda uye kuvhura nguva.Iyo polymer inova nechokwadi chekuti inonamira inoramba iri munzvimbo inoshanda kwenguva yakareba, ichibvumira kuisirwa kwakaringana mataira pasina kuoma nguva isati yakwana.
3.2.Yakaderedzwa Sagging
HPMC inobatsira kune anti-sagging zvimiro zvematairi anonamira.Izvi zvakakosha kana uchiisa matiles panzvimbo yakatwasuka, sezvo ichidzivirira matiles kubva pakutsvedza pasi pamberi pekunamatira seti.
3.3.Crack Resistance muGrouts
Mukugadzira grout, HPMC inobatsira kudzivirira kutsemuka nekupa kuchinjika uye kuderedza shrinkage.Izvi zvinonyanya kubatsira munzvimbo umo kushanduka kwekushisa kunogona kukanganisa zvinhu zvekuvaka.
4. Zvikumbiro muPlaster
4.1.Kuvandudzwa Kwekushanda uye Kupararira
HPMC inowanzowedzerwa kune plaster formulations kuwedzera kushanda uye kupararira.Iyo polymer inobatsira kuwana yakapfava uye inowirirana kushandiswa kwepurasita panzvimbo.
4.2.Crack Resistance
Zvakafanana nebasa rayo mumagrouts, HPMC inobatsira mukupwanya kuramba mu plaster.Iyo inoumba firimu inoshanduka inogadzirisa kufamba kwechisikigo kwezvinhu zvekuvaka, kuderedza mukana wekutsemuka.
5. Zvikumbiro muSelf-Leveling Compounds
5.1.Flow Control
Mumakomisheni ekuzvimiririra, HPMC inoshandiswa kudzora kuyerera uye kuyera zvivakwa.Iyo polymer inovimbisa kugovera kwakafanana uye inobatsira kuchengetedza ukobvu hunodiwa hwekomboni pane iyo nzvimbo yekushandisa.
5.2.Enhanced Adhesion
HPMC inokwidziridza kusungirirwa kwemakomisheni ega-leveling kune akasiyana substrates, ichipa chisungo chakasimba uye chakasimba.Izvi zvakakosha pakuita kwenguva refu kwenzvimbo yakasimudzwa.
6. Mhedziso
Hydroxypropyl Methyl Cellulose inoita basa rakakosha mukusimudzira kushanda kwezvinhu zvakasiyana siyana zvekuvaka.Mashandisirwo ayo mumatope, zvinonamira mataira, grouts, plaster, uye self-leveling makomisheni anoratidza kugona kwayo uye kushanda kwayo muindasitiri yekuvaka.Iwo akasarudzika zvimiro zveHPMC, zvinosanganisira kuchengetwa kwemvura, kukora, uye yakagadziridzwa adhesion, inobatsira kune iyo yese mhando, kusimba, uye kushanda kwezvinhu izvi zvekuvaka.Sezvo indasitiri yekuvaka ichienderera mberi nekushanduka, HPMC inoramba iri chinhu chakakosha mukugadzirwa kwezvinhu zvepamberi uye zvepamusoro-soro zvekuvaka.
