Upfu hwepolymer hunonyungudika (RDP)chinhu chakakosha chepolymer cheorganic, chinoshandiswa zvakanyanya muminda yakawanda yakadai sekuvaka, zvekuvaka, zvekushongedza uye maindasitiri. Ihupfu hunoyerera hunowanikwa kuburikidza ne emulsions dzekuomesa ne spray (senge vinyl acetate-ethylene copolymers, vinyl acetate-acrylate copolymers, nezvimwewo). Hupfu uhwu hunogona kuparadzirwa zvakare kuti hugadzire emulsion yakagadzikana mushure mekusanganiswa nemvura, nokudaro huchichengetedza mashandiro e emulsion yekutanga.
1. Hunhu hwepakutanga
Upfu hwepolymer hunonyungudika hune hunhu hunotevera hwakakosha:
Kugona kunyungudika zvakanaka: Inogona kunyungudika nekukurumidza kuita emulsion chaiyo mumvura, zvichiita kuti ishande zvakanaka pakuvaka.
Kushanda zvakanaka kwekubatanidza: Kuvandudza simba rekubatanidza pakati pezvinhu ne substrate.
Kuvandudza kuchinjika: Wedzera kusimba kwechinhu chacho uye yakakodzera kune mamwe mashandisirwo anoda kuchinjika kwakanyanya.
Kusapindirana nemvura uye kusapindirana nealkali: Ichiri kugadzikana munzvimbo dzine alkali dzakadai sesimende kana lime.
Kudzivirira kukwegura uye kudzivirirwa kwemamiriro ekunze: Inoramba ichishanda zvakanaka pasi pemwaranzi ye ultraviolet kana mamiriro ekunze akaoma.
2. Mashandisirwo makuru
Chinonamira chine mataira uye chinonamira chine mataira. Upfu hwepolymer hunoshanduka hunoshandiswa zvakanyanya mukunamira chine mataira. Hunovandudza kuchinjika uye simba rekubatanidza zvinhu zvinonamira zvine mataira, zvichibvumira mataira kubatanidzwa zvakasimba pazvikamu zvakasiyana-siyana, kunyanya zvakakodzera mataira makuru, asinganyuri mvura yakawanda.
Upfu hweputty neputty yekunze yemadziro Kuwedzera upfu hwepolymer hunodzoserwa kuhupfu hweputty yemukati nekunze yemadziro kunogona kuvandudza zvakanyanya kunamira, kuramba mvura uye mashandiro ekuvaka kweputty. Kunyanya mukushandiswa kwemadziro ekunze, kuramba kuripo kwemamiriro ekunze kwakanyanya kunoita basa rakakosha mukudzivirira kudonha kwehupfu nekutsemuka.
Zvinhu zvepasi zvinozvienzanisa Uriri hwesimende hunozvienzanisa hunoda kupfava uye kunamira zvakanaka. Upfu hwepolymer hunonyungudika hunogona kuvandudza nyore kwekuvaka uye hunhu hwekugadzira firimu, uye kuderedza kutsemuka nekupatsanuka.
Sisitimu yekuisa simbi mudura (senge sisitimu yekuisa simbi mudura rekunze reEIFS) Kuwedzera upfu hwepolymer hunodzoserwa mudura rekuisa simbi ...
Dura risingapindi mvura Kushandisa RDP mufomura yedura risingapindi mvura kunogona kuwedzera zvakanyanya kuchinjika uye kusapinda mvura kwechinhu chacho, kuitira kuti chigone kuramba chichishanda munzvimbo ine hunyoro uye inogara kwenguva refu ichisangana nemvura.
Kugadzirisa dhaka nechinhu chinobatanidza dhaka Upfu hwepolymer hunodzokororwa hunogona kunatsiridza kunamira uye ductility yedhaka rekugadzirisa kudzivirira kutsemuka munzvimbo yakagadziriswa. Kuwedzera RDP kune chinhu chinobatanidza dhaka kunogona kuwedzera simba rekubatanidza pakati pezvikamu zvakasiyana zvezvinhu.
Zvinhu zvakagadzirwa negypsum Kushandisa upfu hwepolymer hunosanganiswa negypsum uye gypsum binders kunogona kuvandudza simba rekubatanidza, kuramba kutsemuka uye kushanda zvakanaka kwekuvaka, uye chinhu chakakosha chezvinhu zvekuvaka zvakasvibira.
3. Zvakanakira zvekushandisa
Kuvaka kuri nyore Upfu hwepolymer hunonyungudika hunowanzova muchimiro cheupfu hwakaoma uye hunogona kusanganiswa zvakananga nezvimwe zvinhu zvakaoma (senge simende, jecha, nezvimwewo) pasina imwe nzira yekuwedzera emulsification. Hunogona kushandiswa panzvimbo yacho nekuwedzera mvura, iyo iri nyore kutakurwa uye kuvaka.
Kuvandudza mashandiro akazara Haingobatsiri chete pakubatanidza dhaka, asiwo inovandudza hunhu hwayo hwakakwana hwemuviri hwakadai sekudzivirira kutsemuka, kuramba chando, kuramba kupera uye kuchinjika. Chinhu chakakosha chekuwedzera kunaka kwezvinhu zvekuvaka.
Kudzivirirwa kwezvakatipoteredza uye kuchengetedzeka. Upfu hwepolymer hunonyungudika hunobviswa patsva hauna chepfu uye hauna njodzi, hunosangana nezvinodiwa nezvivakwa zvemazuva ano zvekuchengetedza zvakatipoteredza uye kuburitsa maVOC mashoma, uye huri kushandiswa zvakanyanya muzvivakwa zvakasvibira.
4. Mafambiro ebudiriro yeramangwana
Nekuda kwekuwedzera kwezvinodiwa zvekuvaka zvine hungwaru uye zvisingakuvadzi nharaunda uye kuvandudzwa kuri kuramba kuchienderera mberi kwetekinoroji yekuvaka, fomura uye mashandiro eRedispersible polymer powder ari kugadziriswawo, zvichienda kune kunamira kwakanyanya, kuramba kupisa kwakanyanya, uye kuburitsa kwakaderera kweVOC. Panguva imwe chete, pamwe chete neminda mitsva yezvinhu zvakaita se nanotechnology nezvinhu zvakagadzirwa nebio, kushandiswa kwenguva refu uye kushanda kweRDP kuchavawo chinangwa chekutsvagisa nekuvandudza mune ramangwana.
Sechinhu chinoshanda chepolymer,RDPine basa guru muzvivakwa zvemazuva ano uye zvekuvaka zvemaindasitiri nekuda kwekushanda kwayo kwakanaka uye kushandiswa kwakasiyana-siyana. Kubva pakugadzira mataira kusvika pakuenzana nemadziro, kubva pakuvaka pasi kusvika pakugadzirisa mvura, ine chinangwa chekuvandudza mashandiro ezvigadzirwa uye kushanda zvakanaka kwekuvaka, uye inosimudzira indasitiri yese yezvigadzirwa zvekuvaka kuti ienderere mberi kune mhando yepamusoro uye nzira dzisingakuvadzi nharaunda.
