Basa reHydroxypropyl Methylcellulose (HPMC) muMortars uye Renders
Matope uye madhiri anoita mabasa akakosha mukuvaka, achipa kutendeseka kwechimiro, kuramba mamiriro ekunze, uye kukwezva kwezvivakwa. Kwemakore, kufambira mberi kwezvinhu zvekuvaka kwakatungamira mukugadzirwa kwezvinowedzera kuwedzera zvimiro zvedhaka uye render. Chimwe chekuwedzera chakadai kuwana mukurumbira iHydroxypropyl Methylcellulose (HPMC).
Kunzwisisa HPMC:
Hydroxypropyl Methylcellulose (HPMC)is a non-ionic cellulose ether inotorwa kubva kumapolima echisikigo, kunyanya cellulose. Inogadzirwa kuburikidza nekuita kwealkali cellulose ine methyl chloride uye propylene oxide. HPMC inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, anosanganisira kuvaka, mishonga, chikafu, uye zvizorwa, nekuda kwezvimiro zvayo zvakasiyana.
Properties of HPMC:
Kuchengeta Mvura: HPMC inoumba firimu rakatetepa kana rakasanganiswa nemvura, richivandudza kuchengetedza kwemvura kwematehwe uye madhiri. Izvi zvinodzivirira kuomeswa nguva isati yakwana, kuve nechokwadi chekuti hydration yesimentitious zvinhu uye kuwedzera kushanda.
Kuvandudzwa Kwekushanda: Kuwedzeredzwa kweHPMC kunopa mhedzisiro yekuzora, kufambisa kupararira uye kushandiswa kwemateki uye render. Inowedzera kuwirirana uye kuwirirana kwemusanganiswa, zvichiita kuti zvive nyore kupera.
Adhesion: HPMC inonamira kunamatira kwedhaka uye inopa kune akasiyana substrates, senge kongiri, zvidhinha, uye dombo. Izvi zvinosimudzira zvisungo zvakasimba, zvichideredza njodzi yeku delamination kana kuvharwa nekufamba kwenguva.
Yakawedzera Nguva Yakavhurika: Nguva yekuvhurika inoreva nguva iyo dhaka kana render rinoramba richishanda risati ragadzika. HPMC inowedzera nguva yakazaruka nekunonoka kumisa kwekutanga kwemusanganiswa, ichibvumira kushandiswa kuri nani uye kupedzisa, kunyanya mumapurojekiti makuru.
Crack Resistance: Kuwedzerwa kweHPMC kunonatsiridza kuchinjika uye elasticity yematope uye inoshandura, ichideredza mukana wekutsemuka nekuda kwekuderera kana kuwedzera kwemafuta. Izvi zvinowedzera kusimba uye hupenyu hurefu hwechimiro.
Mabhenefiti eHPMC muMortars uye Renders:
Kuenderana:HPMCinochengetedza kufanana mudhaka uye inopa musanganiswa, kuderedza misiyano yezvivakwa zvakaita sesimba, density, uye kunamatira. Izvi zvinotungamira kune kuenderana kuita uye mhando mumabheji akasiyana.
Versatility: HPMC inogona kuiswa mudhaka rakasiyana-siyana uye inopa maumbirwo, kusanganisira simende-based, lime-based, uye gypsum-based systems. Inogadzirisa zvakanaka kune akasiyana substrates uye mamiriro ezvakatipoteredza, zvichiita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa.
Kugara kwenguva refu: Madhiri uye anopa akasimbiswa neHPMC anoratidza kukwidziridzwa kupikisa kune zvakatipoteredza zvinhu zvakaita sehunyoro, kushanduka kwetembiricha, uye kuratidzwa kwemakemikari. Izvi zvinovandudza kusimba kwese uye kusimba kwechimiro.
Kugarisana: HPMC inowirirana nezvimwe zvinowedzera uye zvinosanganiswa zvinowanzoshandiswa mudhaka uye inopa maumbirwo, senge air-entraining agents, plasticizers, uye pozzolanic zvinhu. Izvo hazvikanganisi nekuita kweizvi zvinowedzera, zvichibvumira synergistic mhedzisiro.
Zvishandiso zveHPMC muMortars uye Renders:
Exterior Finishes: HPMC-yakakwenenzverwa renders inowanzoshandiswa kupedzisa kwekunze, ichipa kudzivirira kwemamiriro ekunze uye machira ekushongedza kumafacade. Aya mashanduri anopa kunamira kwakanakisa, kuchinjika, uye kusagadzikana kwekutsemuka, kuwedzera kutaridzika uye kusimba kwezvivakwa.
Tile Adhesives: HPMC chinhu chakakosha chekunamatira mataira, kuvandudza kusimba kwekubatanidza uye kushanda kweiyo inonamira dhaka. Inochengetedza kunyorova kwakakodzera uye kufukidzwa kwe substrate uye inodzivirira kuoma kusati kwasvika kwekunamatira.
Gadzirisa Madhiri: HPMC-yakagadziridzwa dhaka rekugadzirisa rinoshandiswa kupeta, kumisazve, uye kudzoreredza zvakakanganisika kongiri zvimiro. Aya madhaka anoratidza kunamatira kwakanyanya kune substrate uye kuenderana nekongiri iripo, kuve nechokwadi chekugadziriswa kusina musono.
Skim Coats: Majasi eSkim, anoshandiswa kuenzanisa uye kutsvedzerera nzvimbo dzisina kuenzana, anobatsirwa nekuwedzera kweHPMC. Inopa kuenderana kwakanyoro kune iyo skim jasi, ichibvumira kushanda nyore uye kuwana yakatsetseka, yunifomu kupera.
Hydroxypropyl Methylcellulose (HPMC)inoita basa rakakosha mukusimudzira kushanda, kushanda, uye kusimba kwedhaka uye inopihwa mukushandisa kuvaka. Zvimiro zvayo zvakasiyana, zvakadai sekuchengetedza mvura, kuvandudzwa kwekushanda, kunamatira, uye kuramba kwekuputika, inoita kuti ive yekuwedzera yakakosha yekuwana kupedzisa kwepamusoro uye zvivakwa zvinogara kwenguva refu. Sezvo indasitiri yekuvaka iri kuramba ichishanduka, kushandiswa kweHPMC kunotarisirwa kuwedzera, kutyaira hunyanzvi uye kusimba mune zvekuvaka.
