Redispersible polymer poda (RDP) chinhu chakakosha chekuwedzera mune zvemazuva ano zvekuvaka, kunyanya mune zvinonamira, dhaka, uye plasters.Nekusimudzira chimiro chemuviri uye chemakemikari ezvishandiso izvi, maRDP anoita basa rakakosha mukuvandudza kusimba uye kuita kwemapurojekiti ekuvaka.
Kuumbwa uye Mechanism yeRDP
RDP inogadzirwa nekupfapfaidza-kuomesa emulsion yezvinhu zvepolymeric, kazhinji yakavakirwa pavinyl acetate-ethylene (VAE), acrylic, kana styrene-butadiene.Iyi nzira inoshandura emulsion kuita hupfu hwakatsetseka hunogona kuparadzirwa zvakare mumvura, kudzorera iyo yekutanga polymer dispersion.Kana yawedzerwa kune yakaoma dhaka musanganiswa, RDP inoita zvakare pakubata nemvura, ichigadzira homogeneous uye yakagadzikana firimu mukati meanonamatira matrix.
Kuwedzera Kuramba Kwemvura
Kugadzira Firimu: Pamusoro pe hydration, zvimedu zveRDP zvinobatana kuti zvigadzire inoenderera firimu repolymer mukati meiyo inonamira matrix.Iyi firimu inoshanda sechipingamupinyi, zvakanyanya kuderedza porosity uye kupera kwemvura yekunamatira.Iyo firimu inovharira capillary chiteshi, kudzivirira kupinda kwemvura uye kuwedzera kunamira kwese kwese kudzivirira mvura.
Hydrophobic Properties: Mazhinji eRDP maumbirwo anosanganisira hydrophobic agents kana modifiers zvinowedzera kuwedzera kudzivirira kwemvura.Aya ma hydrophobic components anoderedza kunyura kwemvura kweadhesive, kuve nechokwadi chekushanda kwenguva refu kunyange mumamiriro ekunyorova.
Yakavandudzwa Kubatana uye Kuchinja: RDP inosimudzira kubatana kwemukati wekunamatira, inovandudza chisungo chayo uye kuchinjika.Uku kuchinjika kwakakosha mukudzivirira kuumbwa kwepakatsemuka uye maburi anogona kubvumira mvura kupinda.Iyo inonamira iyo inogona kugarisa kuwedzera kwekupisa uye kuputika pasina kutsemuka inochengetedza kutendeseka kwayo uye kudzivirira kwemvura nekufamba kwenguva.
Kusimudzira Kuramba Kwemamiriro ekunze
UV Kugadzikana: RDP maumbirwo anowanzo gadzirirwa kuramba kusvibiswa kubva kune ultraviolet (UV) mwenje.Iyo firimu repolymer rakagadzirwa neRDP rakagadzika UV, rinochengetedza rinonamira pasi kubva kune zvinokuvadza zvekugara kwenguva refu kwezuva.Uku kugadzikana kunovimbisa kuti chinonamira chinochengeta simba rayo uye elasticity kunyangwe mushure mekuratidzwa kwenguva refu kuchiedza chezuva.
Thermal Resistance: Zvishandiso zvekuvaka zviri pasi pekusiyana kwekushisa kwakanyanya, izvo zvinogona kukonzera kuwedzera uye kuderera.RDP-yakagadziridzwa adhesives anoratidza yakanakisa kupisa kupisa, kuchengetedza simba rebhondi uye kuchinjika pahupamhi hwetembiricha renji.Ichi chivakwa chinodzivirira chinonamira kuti chisaite brittle mukutonhora kwemamiriro ekunze kana kupfava zvakanyanya mumamiriro ekupisa, nekudaro ichiwedzera kumira kwayo kwemamiriro ekunze.
Kupokana neFreeze-Thaw Cycles: Mumamiriro ekunze anotonhora, zvinhu zvinodzokororwa nechando-thaw cycles, izvo zvinogona kunyanya kukuvadza.Iko kuchinjika uye kubatana kunopihwa neRDP kunobatsira zvinonamira kutsungirira aya matenderedzwa pasina kurasikirwa nekuvimbika.Iyo firimu repolymer rinoita sechinhu chinokatyamadza, ichidzikamisa kushushikana kunokonzerwa nechando uye kunyungudika.
Inoshanda Zvikumbiro
Exterior Insulation uye Finish Systems (EIFS): RDP inoshandiswa zvakanyanya muEIFS, uko kushomeka kwemvura nemamiriro ekunze.Iyo polymer poda inova nechokwadi chekuti anonamira muzvikamu mune aya masisitimu anogona kuramba kupinza hunyoro uye kumirisana nemamiriro ekunze akasiyana-siyana, achidzivirira kutendeseka kwechimiro uye kusungirira zvimiro zvehurongwa.
Tile Adhesives uye Grouts: Mune zvese zvemukati uye zvekunze zvekushandisa, mataira anonamira uye grouts akagadziridzwa neRDP anoratidza hukuru hwekuita.Vanodzivisa kupinda kwemvura uye kudzivirira matairi kuti asasununguke kana kukuvadzwa nekuda kwemamiriro ekunze.Izvi zvinonyanya kukosha munzvimbo dzekunze uko mataira anoratidzwa kunaya, chando, uye zuva rakananga.
Gadzirisa Matuta uye Patching Macompounds: Kugadzirisa kongiri uye chigamba, RDP inosimudzira kusimba kwezvinhu zvekugadzirisa.Inoita kuti zvinhu izvi zvibatane zvinobudirira kune kongiri iripo, ichipa mvura isina mvura uye inodzivirira mamiriro ekunze inogadzirisa iyo inowedzera hupenyu hwekugadzirisa.
Mabhenefiti Ezvakatipoteredza uye Zveupfumi
Kuwedzerwa Upenyu Hwakawedzerwa: Nokuvandudza mvura uye kudzivirira kwemamiriro ekunze, RDP inowedzera hupenyu hwekunamatira kuvaka uye zvivakwa zvavanoshandiswa.
Kushanda Kwesimba: Muzvishandiso zvakaita seEIFS, RDP-inonamidzira inonamira inobatsira kuita zvirinani kuvharisa nekuchengetedza kutendeseka kweiyo insulation system.Izvi zvinogona kutungamira kukuchengetedza kwakakosha kwesimba mukudziya uye kutonhora zvivakwa, kukurudzira kusimba.
Yakaderedzwa Marara: Kushandiswa kwezvinonamira zvinogara kwenguva refu, zvinodzivirira mamiriro ekunze kunoderedza marara ekuvaka anogadzirwa nezvinhu zvakakundikana kana kuparara.Izvi zvinobatsira kune dzimwe nzira dzakasimba dzekuvaka uye kuderedza kukanganiswa kwezvakatipoteredza kwemapurojekiti ekuvaka.
Redispersible polymer poda ndeye inoshandura yekuwedzera mune zvekunamira zvekuvaka, ichipa yakakosha mvura uye mamiriro ekunze ekupikisa zvivakwa.Kugona kwayo kuumba inodzivirira yepolymer firimu, yakasanganiswa neiyo hydrophobic hunhu uye yakakwidziridzwa kuchinjika, inoita kuti RDP-yakagadziridzwa inonamira yakasimba kurwisa matambudziko ekunyorova uye kuratidzwa kwemamiriro ekunze.Nekubatanidza RDP muzvivakwa zvekuvaka, vavaki nevainjiniya vanogona kuve nechokwadi chekugara-refu, zvivakwa zvinogara zvakashongedzerwa zvirinani kutsungirira kushushikana kwezvakatipoteredza.Izvi hazvingokwidzi kushanda uye kuvimbika kwemapurojekiti ekuvaka asiwo zvinosimudzira kusimba uye kudhura-muindasitiri.
