Upfu hwepolymer hunonyungudika zvakarendiyo chinhu chikuru chinoshandiswa pakugadzira dhaka rakasanganiswa nehupfu hwakaoma rakaita sedare rakaumbwa nesimende kana gypsum.
Upfu hwelatex hunosanganiswazve ipolymer emulsion inoomeswa nespray uye inounganidzwa kubva pa2um yekutanga kuti igadzire zvidimbu zvakatenderera zve80 ~ 120um. Nekuti pamusoro pezvidimbu zvakafukidzwa neupfu husingararami, hunodzivirira chimiro chakaoma, tinowana hupfu hwepolymer hwakaoma. Hunodururwa zviri nyore kana kuchengetwa mumatura. Kana upfu hwacho hukasanganiswa nemvura, simende kana gypsum-based mortar, hunogona kusanganiswazve, uye zvidimbu zvekutanga (2um) zvirimo zvinozoumbwazve kuita mamiriro akaenzana nelatex yekutanga, saka hunonzi upfu hwelatex hunosanganiswazve.
Inonyungudika zvakanaka, inonyungudika zvakare kuita emulsion kana yasangana nemvura, uye ine hunhu hwemakemikari hwakafanana nehwepakutanga. Nekuwedzera upfu hwepolymer hunonyungudika zvakare mumota yakasanganiswa nesimende kana yakagadzirwa negypsum, hunhu hwakasiyana hwemota hunogona kuvandudzwa,
Munda wekuvaka wakashandiswa
1 Sisitimu Yekudzivirira Madziro Ekunze
Inogona kuona kuti simbi dzakanamira zvakanaka pakati pesimbi dzakaoma nepolystyrene board nedzimwe nzvimbo dzakaoma, uye hazvisi nyore kuibvisa nekudonha. Inosimudzira kuchinjika, inodzivirira kukuvadzwa uye inovandudza kusimba kwemutseko.
2 namira yemataira
Inopa chisungo chakasimba kune dhaka, zvichipa dhaka mukana wekuti rikwanise kudzvanya ma coefficients akasiyana ekuwedzera kwekupisa kwe substrate ne tile.
3 caulk
Upfu hwepolymer hunonyungudika hunoita kuti dhaka risanyungudike uye hunodzivirira kupinda kwemvura. Panguva imwe chete, hunonyatsonamira pamucheto wetaira, hushoma kuderera uye hunochinjika.
4 interface dhaka
Inogona kuvhara zviri nani mukaha we substrate, kuderedza kunyudzwa kwemvura pamadziro, kuvandudza simba repamusoro pe substrate, uye kuona kuti dhaka rinonamira.
5 Dura repasi rinozvienzanisa
Wedzera simba rekubatana nechikamu chezasi, wedzera simba rekubatana, wedzera simba rekubatana, simba rekubatana uye simba rekukombama kwemota.
6 dhaka risingapindi mvura
Upfu hwelatex hunonyungudika hunogona kuwedzera kushanda zvakanaka; kuwedzerawo kuchengetedza mvura; kuwedzera kunyorova kwesimende; kuderedza elastic modulus yedhaka uye kuwedzera kuenderana nehwaro hwepasi. Kuvandudza huwandu hwedhaka, kuwedzera kuchinjika, kuramba kutsemuka kana kugona kudzikamisa dhaka.
7 kugadzirisa dhaka
Iva nechokwadi chekuti dhaka rakanamira uye wedzera kugara kwenguva refu kwenzvimbo yakagadziriswa. Kuderedza elastic modulus kunoita kuti irambe yakasimba pakumanikidzwa.
8 putty
Deredza elastic modulus yemortar, wedzera kuenderana ne base layer, wedzera kuchinjika, kudzivirira kutsemuka, wedzera kuramba kudonha kwehupfu, kuitira kuti putty ive nekusapinda kwemvura uye kuramba hunyoro, izvo zvinogona kugadzirisa kukuvara kwekumanikidzwa kwekupisa.
