Redispersible Polymer Powder (RPP) ihupfu huchena hunogadzirwa kubva mupolymer emulsion kuburikidza nespray drying process uye hunoshandiswa zvakanyanya mumunda wezvinhu zvekuvaka. Basa rayo guru nderekuvandudza mashandiro ezvigadzirwa zvekuvaka, zvakaita sekuvandudza simba rekubatana, kuramba kutsemuka, kuchinjika uye kuramba mvura.
1. Zvinhu zvekupurasita pamadziro nekuenzana
Upfu hwelatex hunosanganiswa hunoshandiswa zvakanyanya mukugadzira madziro nekuisa madziro muzvikamu zvakasiyana. Kuwedzera huwandu hwakati hwelatex mudura resimende rekare kunogona kuvandudza kuchinjika uye kunamira kwedura, zvichiita kuti dura rinyatsonamira pasi uye risakonzere kutsemuka nekupwanyika. Pamusoro pezvo, kuwedzerwa kwelatex powder kunogonawo kuvandudza mashandiro ekuvaka dura, zvichiita kuti dura rive nyore kuisa nekupukuta, nokudaro zvichiita kuti madziro ave akatsetseka uye akapfava.
2. Kunamira mataira
Muma tile adhesives, kushandiswa kwe latex powder inonyungudika zvakare kwave kushandiswa muindasitiri. Zvichienzaniswa nema tile adhesives echinyakare akavakirwa pa simende, adhesives ane latex powder ane simba rekubatanidza rakakwirira uye hunhu hunodzivirira kutsvedza. Latex powder inopa adhesive kushanduka kuri nani, zvichiita kuti ikwanise kuchinjika kune akasiyana expansion coefficients e substrate nema ceramic tiles mukuchinja kwetembiricha nehunyoro, zvichideredza njodzi yekutsemuka nekudonha. Pamusoro pezvo, latex powder inovandudzawo kudzivirira mvura uye chando che binder, zvichiita kuti ive yakakodzera munzvimbo dzakasiyana-siyana dzakaoma dzemukati nekunze.
3. Duri risingapindi mvura
Kushandiswa kwehupfu hwelatex hunonyungudika mudura risingapindi mvura kwakakoshawo zvikuru. Hupfu hwelatex hunoshanda nesimende nezvimwe zvinowedzera kuti hugadzire dura rakakora risingapindi mvura rinogona kudzivirira hunyoro kupinda. Rudzi urwu rwedura risingapindi mvura runoshandiswa zvakanyanya muzvikamu zvekuvaka zvinoda kugadziriswa kwemvura, zvakaita sedzimba dzepasi, matenga, uye madziva ekushambira. Nekuda kwekuwedzera hupfu hwelatex, dura risingapindi mvura harina chete hunhu hwakanaka hwemvura, asiwo rinochengetedza kufema kwakanaka, nokudaro richidzivirira matambudziko ehunyoro mukati mechivako.
4. Sisitimu yekudzivirira madziro ekunze
MuExternal Thermal Insulation Composite Systems (ETICS), upfu hwelatex hunonyungudika hunoita basa guru. Hunowedzerwa kune dhaka rekubatanidza rinoshandiswa pakuisa insulation panels kuti huvandudze simba rekubatanidza uye kuchinjika kwedhaka, nokudaro zvichiita kuti pave nechisungo chakasimba pakati pedhaka rekudzivirira insulation nemadziro epasi uye kudzivirira matambudziko ekutsemuka kana kudonha. Pamusoro pezvo, upfu hwelatex hunovandudzawo kuramba kwechando-kunyungudika uye kugara kwenguva refu kwedhaka rekubatanidza, zvichibvumira system yekuisa insulation yekunze kuchengetedza kushanda kwakanaka mumamiriro akasiyana-siyana ekunze.
5. Dura rinozvienzanisa
Mota inodzika yega imota inoyerera zvakanyanya inoiswa pasi iyo inoenzanisa yoga pasi uye inoita kuti pamusoro payo pave pakachena, pakaenzana. Kushandiswa kweupfu hwelatex hunonyungudika mumota inodzika yega kunowedzera kuyerera uye kunamira kwemota, zvichiita kuti ifambe nekukurumidza mukati menzvimbo yakakura uye ienderane. Pamusoro pezvo, kuwedzerwa kweupfu hwelatex kunowedzerawo simba rekudzvanya uye hunhu hwekudzivirira kupfeka kwemota inodzika yega, zvichiita kuti pasi pagare kwenguva refu.
6. Kugadzirisa dhaka
Hazvidzivisiki kuti pachava nekutsemuka kana kukuvara panguva yekushandiswa kwezvivakwa, uye kugadzira dhaka ndiyo inoshandiswa kugadzirisa zvikanganiso izvi. Kuiswa kwehupfu hwelatex hunonyungudika zvakare kunoita kuti dhaka rekugadzirisa rinamire zviri nani uye rigone kuchinjika, zvichiita kuti rikwanise kuzadza dhaka zviri nani uye kugadzira musanganiswa wakanaka nezvinhu zvekuvaka zvepakutanga. Hupfu hwelatex hunovandudzawo kuramba kwedhaka rekugadzirisa uye kugara kwenguva refu, zvichiita kuti nzvimbo yakagadziriswa irambe yakasimba kwenguva yakareba.
7. Kuputira kunodzivirira moto
Muzvipfeko zvinodzivirira moto, kuwedzera upfu hwelatex hunonyungudika kunogona kunatsiridza kunamira uye kuchinjika kwejira, zvichiita kuti jira rigadzire jira rinodzivirira mumoto, zvichidzivirira kukuvara kwezvivakwa nemoto uye tembiricha yakakwira. Pamusoro pezvo, upfu hwelatex hunogonawo kuvandudza kuramba mvura uye kuramba kukwegura kwezvipfeko zvinodzivirira moto uye kuwedzera hupenyu hwazvo hwekushanda.
8. Guruu rekuvaka
Upfu hwelatex hunosanganiswa zvakare ndeimwe yezvinhu zvakakosha pakugadzira guruu rekuvaka. Hunoita kuti guruu rinamire zviri nani uye rigare kwenguva refu, zvichiita kuti rikwanise kushandiswa pakubatanidza zvinhu zvakasiyana-siyana zvekuvaka, zvakaita sehuni, gypsum board, matombo, nezvimwewo. Kugona kushandiswa kweguruu relatex kunoita kuti guruu rekuvaka rive neruzivo rwakasiyana-siyana, kunyanya munyaya dzekushongedza nekushongedza.
Sechinowedzerwa chinoshanda, upfu hwelatex hunonyungudika hune mabasa akasiyana-siyana mumunda wekuvaka. Hahungobatsiri chete pakuvandudza hunhu hwezvinhu zvekuvaka, asiwo hunowedzera nyore uye kushanda zvakanaka kwekuvaka. Nekuvandudzwa kuri kuitwa tekinoroji yekuvaka, mikana yekushandisa upfu hwelatex hunonyungudika huchava hwakawanda uye huchava chinhu chakakosha uye chakakosha chezvinhu zvemazuva ano zvekuvaka.
