Mukuvaka kwemazuva ano, mashandiro edhaka anokanganisa zvakananga kunaka uye kushanda zvakanaka kwepurojekiti. Kuti zvivandudze kuchengetedza mvura, kushanda zvakanaka, uye kunamira kwedhaka,hydroxypropyl methylcellulose (HPMC)Inoshandiswa zvakanyanya mumhando dzakasiyana dzemortar dzakasanganiswa nedry-mix, dzakadai sematiles, plaster mortars, self-leveling mortars, uye thermal insulation mortars. Sepolymer inoshanda zvikuru mumvura inonyunguduka, HPMC yemortar inovandudza zvakanyanya kushanda kwemortar kuburikidza nechimiro chayo chakasiyana chemamorekuru uye hunhu hwayo hwefizikisi, zvichiita kuti ive chinhu chakakosha chinowedzera mukugadzirwa kwemortar yemazuva ano.
1.HPMC inoratidza kuchengetedza mvura zvakanaka. Mumasystem emortar, HPMC inoumba firimu repolymer rakakora pamusoro pezvikamu zvesimende, zvichideredza kurasikirwa nemvura panguva yekusanganisa, kushandisa, uye kutanga kwayo. Kuchengetedza mvura uku hakungovimbisi chete kuti simende iwane mvura yakakwana uye kunowedzera simba rayo, asiwo kunodzivirira kupera mvura mumuviri nekutsemuka kunokonzerwa nekunwa mvura yakawanda kana kupisa kwakanyanya mubase layer. Kune zvigadzirwa zvakaita sematiles neputty powders zvinoda kushandiswa mu thin-layer, kuchengetedza mvura kweHPMC kwakakosha zvikuru, zvichiwedzera nguva yekuvhurika uye nguva yekugadzirisa, zvichivandudza kushivirira kwekushandisa.
2.HPMC inogona kuvandudza zvakanyanya hunhu hwe rheological uye kushanda kwe dhaka. Huwandu hwakakodzera hwe HPMC hunogona kuwedzera kunaka kwedhaka, zvichipa mafuta akanaka uye thixotropy panguva yekusanganisa nekushandisa, kudzivirira kubuda ropa nekupatsanurwa, uye kuona kuti plaster ne coating zviri nyore. Inovandudzawo hunhu hwedhaka husingatsvedzeri, ichivimbisa kuti mataira kana mabhodhi ekudzivirira haatsvedzeri kana kuchinja panguva yekushandisa. Kudzora uku kwe rheological kwe HPMC kunoita kuti ma applicators akwanise kudzora ukobvu hwedhaka uye kutsvedzerera kwepamusoro, nokudaro zvichivandudza kushanda zvakanaka kwedhaka uye mhando yechigadzirwa chekupedzisira.
3.HPMC ine hunhu hwakanaka hwekukora uye kudzikamisa mudhaka. Nekuti chimiro chayo chepolymer cheni chinoita mhinduro yakasimba yecolloidal mumvura, HPMC inogona kuwedzera zvakanyanya viscosity yedhaka pazviyero zvishoma, ichidzivirira kupatsanurwa uye kugadzikana panguva yekuchengetwa nekushandiswa. Izvi hazvingobatsiri chete kugadzikana uye kushandiswa kwedhaka rakaoma, asiwo zvinobatsira kuvandudza kuchengetedza kwechigadzirwa uye mashandiro ekurongedza.
4.HPMC inowedzerawo kuramba kubatana uye kutsemuka kwemortar. Firimu repolymer rainoumba rinoratidza kuchinjika uye kusimba kwaro, richishanda sebhiriji mushure mekunge mortar yaoma, richideredza kutsemuka kunokonzerwa nekuomarara. Uyezve, inovandudza simba rekubatana pakati pemortar ne substrate kana pamusoro pe tile, zvichiita kuti layer yapera igare kwenguva refu uye igare kwenguva refu. Mhedzisiro yekusimbisa bond yeHPMC inonyanya kukosha mu exterior wall insulation systems uye adhesive mortars.
5.Mukushandiswa kwaro, mhando dzakasiyana dzedhaka dzinoda hunyanzvi hwakasiyana hweHPMC. Semuenzaniso, zvinonamira zvemataira zvinowanzoshandisa HPMC inonamira pakati nepakati kusvika pakakwirira, inoburitsa zvishoma nezvishoma kuti ive nechokwadi chekuti haitsvedzi uye haichengetwi nemvura, nepo dhaka dzinozvienzanisa dzakakodzera HPMC inonyunguduka nekukurumidza kuti irambe ichinyorova uye ichishandiswa zvakanaka. Nekusarudza zvakanaka dhaka, mwero wekutsiva, uye chimiro chezvidimbu, vanogadzira vanogona kuwana chiyero chakanaka pakati pekuchengetedza mvura, kunyorova, uye simba.
6. HPMCyedhaka, ine hunhu hwayo hwekuchengetedza mvura, kukora, mafuta, uye kubatana, yave chinhu chakakosha chinowedzera mashandiro ekuvaka kwedhaka rakasanganiswa nemvura. Haingogadzirise ruzivo rwekuvaka chete asiwo inovandudza zvakanyanya kunaka kweprojekiti uye kugara kwenguva refu. Nekugadzirwa kwezvinhu zvekuvaka zvakasvibira uye dhaka dzinoshanda zvakanyanya, kushandiswa kweHPMC muzvinhu zvekuvaka kucharamba kuchikura, uye hunyanzvi hwayo hwetekinoroji uye kugadzirisa zvigadzirwa zvichave nzira dzakakosha dzekusimudzira mashandiro ezvigadzirwa zvekuvaka.
