Zvigadzirwa zvepolymer powder zvinosanganiswa nemvura ipoda dzinosanganiswa nemvura, dzakakamurwa kuita ethylene/vinyl acetate copolymers, vinyl acetate/tertiary ethylene carbonate copolymers, acrylic copolymers, nezvimwewo, nepolyvinyl alcohol seprotective colloid. Upfu uhwu hunogona kusanganiswa nekukurumidza kuita emulsion mushure mekusangana nemvura. Nekuda kwekukwanisa kukuru kwekubatanidza uye hunhu hwakasiyana hwepolymer powders dzinosanganiswa nemvura, dzakadai se: kudzivirira mvura, kuvaka uye kupisa, nezvimwewo, mashandisirwo azvo akafara zvikuru.
Hunhu hwekushanda
Ine simba guru rekubatanidza, inovandudza kuchinjika kwemota uye ine nguva yakareba yekuvhura, inoisa mumota nekudzivirira kwakanaka kwealkali, uye inovandudza kunamira, simba reflexural, kudzivirira mvura, plasticity uye kuramba kupfeka kwemota. Kuwedzera kune hunhu hwekuvaka, ine kuchinjika kwakasimba mumota inochinjika inodzivirira kupwanyika.
Munda wekushandisa
1. Sisitimu yekudzivirira kupisa pamadziro ekunze: Dura rekubatanidza: Iva nechokwadi chekuti dura rinobatanidza zvakasimba madziro nebhodhi reEPS. Wedzera simba rekubatanidza. Kupurasita dura: kuve nechokwadi chekuti simba remuchina, kuramba kutsemuka uye kugara kwenguva refu kwesisitimu yekudzivirira kupisa, uye kuramba kukanganiswa.
2. Chinonamira mataira uye chinonamira caulking: Chinonamira mataira: Chinopa chisungo chakasimba chedhaka, uye chinopa dhaka rusununguko rwakakwana rwekukwesha ma coefficients akasiyana ekuwedzera kwekupisa kwe substrate ne ceramic tile. Chinozadza: Ita kuti dhaka risapinde mumvura uye kudzivirira kupinda kwemvura. Panguva imwe chete, ine kubatana kwakanaka nemucheto wedhaka, kuderera kwakaderera uye kuchinjika kwakaderera.
3. Kugadzirisa mataira uye putty yekupurasita matanda: Wedzera kunamira uye simba rekubatanidza putty pane zvinhu zvakakosha (zvakadai semataira, mosaic, plywood nedzimwe nzvimbo dzakatsetseka), uye iva nechokwadi chekuti putty ine kuchinjika kwakanaka kwekumanikidza kuwedzera kwe substrate.
Chechina, putty yemukati neyekunze yemadziro: vandudza simba rekubatanidza putty kuitira kuti putty ive nechokwadi chekuti ine hunyanzvi hwakati hwekudzivirira mhedzisiro yekuwanda nekudzika kwakasiyana kunokonzerwa nezvikamu zvakasiyana zvebase layers. Iva nechokwadi chekuti putty ine kutsungirira kwakanaka kwekukwegura, kunyura uye kudzivirira hunyoro.
5. Dura repasi rinozvienzanisa: simbisa kuti dura repasi rinoenderana ne elastic modulus uye kuti dura rirambe richikotamira uye richiramba kutsemuka. Wedzera simba rekupfeka, simba rekusunga uye kubatana kwedura.
6. Dura rekubatanidza: simbisa kusimba kwepamusoro pe substrate uye simbisa kubatana kwedura.
7. Dura risingapindi mvura rakagadzirwa nesimende: chengetedza mashandiro edura risingapindi mvura, uye panguva imwe chete nyatsobatana nepasi kuti uwedzere kusimba kwekudzvanya uye kugonya kwedura.
8. Gadzirisa dhaka: iva nechokwadi chekuti kuwedzera kwedhaka nehwaro hwechinhu chinoenderana, uye deredza elastic modulus yedhaka. Ita shuwa kuti dhaka rine simba rekudzivirira mvura, kufema zvakanaka uye kunamira zvakakwana.
9. Kupurasita nematombo: kunovandudza kuchengetwa kwemvura. Kunoderedza kurasikirwa kwemvura kuzvinhu zvine maburi. Kuvandudza nyore kwekushanda kwekuvaka uye kunovandudza kushanda zvakanaka kwebasa.
Zvakanakira
Hazvidi kuchengetwa uye kutakurwa nemvura, zvichideredza mari yekufambisa; nguva refu yekuchengetedza, antifreeze, zviri nyore kuchengeta; kurongedza kudiki, huremu hwakareruka, zviri nyore kushandisa; zvinogona kusanganiswa nema hydraulic binders kuti zvigadzire synthetic resin yakagadziriswa. Premix inogona kushandiswa chete nekuwedzera mvura, izvo zvisingangodziviriri zvikanganiso pakusanganisa panzvimbo yekuvaka chete, asiwo zvinovandudza kuchengetedzeka kwekubata kwechigadzirwa.
