Hydroxypropyl methylcellulose (HPMC)ipurasitiki inonyungudika mumvura inoshanda zvakanyanya inoshandiswa zvakanyanya mumamortar emazuva ano akaoma, ichiita basa rinokosha, kunyanya mumasisitimu ekunamira mataira. Nekuwedzera kukurumbira kwekuisa mataira matete uye mataira makuru, zvinodiwa zvakanyanya zvinoiswa pakugona kushanda, simba rekubatanidza, uye kugadzikana kwemamaira emataira. HPMC ndeimwe yeanowedzera basa akakosha anoita kuti pave nekuenzana uku kwekushanda.
Basa guru reHPMC nderekuvandudza kuchengetedza mvura kwematiles ekunamira. Mataira ekunamira anoda mvura yakakwana panguva yekuisa simende kuti ive nechokwadi chekuti simende haina mvura yakakwana. Kana mvura isina kukwana, mvura inonyungudutswa nyore nyore ne substrate kana mataira, zvichikonzera kuti simende isanyatso nyorova uye kuderera kukuru kwesimba rematiles. Kana yakanyungudutswa mumvura, HPMC inogadzira chimiro che polymer network chakafanana, ichivhara mvura yakasununguka uye inononoka kurasikirwa nemvura zvakanyanya, zvichibvumira kuti matiles ekunamira arambe akasimba panguva yaanoshanda. Izvi zvinonyanya kukosha kune ma substrate ane mvura yakawanda kana kuti ekuvaka munzvimbo dzakaoma, dzinopisa zvakanyanya.
HPMC inovandudza zvakanyanya kushanda uye hunhu hwema tile adhesives. Nekugadzirisa ma HPMC viscosity grades akasiyana, tile adhesive inogona kuwana kusanganiswa kwakanaka uye kwakapfava, ine resistance iri pakati nepakati panguva yekushandiswa, kudzivirira kutsemuka kana kutsemuka. Thixotropy yakanaka inobvumira tile adhesive kuti ive fluid yakawanda pasi pekumanikidzwa uye nekukurumidza kudzoka kugadzikana kwayo mushure mekunge kumanikidzwa kwabviswa, zvichiita kuti patani ye trowel ine notched iite, zvichivandudza kufanana kwekuisa mataira uye kushanda zvakanaka kwekuvaka, uye kuderedza marara ezvinhu.
HPMC ine basa guru mukudzivirira kutsvedza uye kudzivirira kudonha. Pakuisa mataira pamadziro, huremu hwemataira hunogona kukonzera kutsvedza zviri nyore, zvichikanganisa kunyatsogadzirwa uye kutokonzera kupatsanurwa. Nekuvandudza kushushikana kwegoho uye kugadzikana kwechimiro chesystem, HPMC inoita kuti glue yemataira ive nehunhu hwakanaka hwekudzivirira kutsvedza uku ichichengetedza simba rakanaka rekubatanidza, ichiva nechokwadi chekuti mataira anoramba akagadzikana uye haachinji panguva yekutanga kwekuisa, zvichizadzisa zvinodiwa zvekudzivirira kutsvedza mumatanho akakodzera akadai seEN12004.
HPMC inobatsirawo kuvandudza simba rekubatanidza uye kugara kwenguva refu kwezvinonamira zvemataira. Nzvimbo yakanaka yekuchengetedza mvura inobatsira kuti simende irambe ichinyorova zvakakwana, zvichiita kuti chigadzirwa chive nemafuta akawanda, nokudaro zvichiwedzera kubatana pakati pezvinonamira zvemataira ne substrate nekumashure kwemataira. Panguva iyi, HPMC inogonawo kuvandudza chimiro chemota, kuderedza kuoma kwekuoma, uye kuderedza kugadzirwa kwezvimedu zvidiki, nokudaro zvichikanganisa kugadzikana kwenguva refu kwekubatanidza uye kuramba kukwegura.
Mukushandiswa kunoshanda, kusarudzwa kwakakodzera kweHPMCKusviba uye mwero wekutsiva kwakakosha. Kusviba kwakaderera kweHPMC kunobatsira kuti mvura ifambe zvakanaka uye iite mafuta, nepo kusviba kwepakati kusvika kwepamusoro kweHPMC kunoshanda zviri nani mukuchengetedza mvura uye kudzivirira kutsvedza. Kazhinji, huwandu hweHPMC hunowedzerwa mumhando dzematiles adhesive hwakaderera, asi kukanganisa kwayo pakushanda kwayo kwakakosha. Nokudaro, kusarudzwa kwakanangana kunodiwa zvichienderana nerudzi rwematiles, nzira yekuvaka, uye mamiriro ekunze.
