Redispersible Polymer Powders (RDP) yawedzera kukosha muindasitiri yekuvaka, kunyanya mumatope binder kongiri musanganiswa. Kubatanidzwa kwavo kunounza akawanda mabhenefiti anowedzera kuita uye kusimba kwekongiri.
Chemical Properties yeRDP
RDPs inogadzirwa kuburikidza nekupfapfaidza-kuomesa emulsion yepolymer, zvichikonzera hupfu hwakatsetseka hunogona kuparadzirwa nyore nyore mumvura. Mapolymer anonyanya kushandiswa anosanganisira vinyl acetate-ethylene (VAE), vinyl acetate copolymers, uye acrylic copolymers. Aya mapolymer anosarudzwa kune avo anonamira zvimiro, kuchinjika, uye kugona kusimudzira akasiyana emuviri maitiro edhaka nekongiri.
Pakusanganiswa nemvura, maRDP anodzokera kune yavo yekutanga polymer state, vachigadzira polymer firimu mukati mekongiri matrix. Iyi firimu inopa akati wandei anobatsira zvivakwa, sekunatsiridza kunamatira, kuchinjika, uye kuramba kune zvakatipoteredza zvinhu. Iyo kemikari inoumbwa yeRDPs inovatendera kuti vabatane zvinobudirira nesementitious zvinhu, kusimudzira zvese zvitsva uye zvakaomeswa zvimiro zvedhaka nekongiri.
Mabhenefiti eRDP muMortar Binder Concrete Mixtures
Kuvandudzwa Kwekushanda:
RDPs inosimudzira kushanda kwedhaka uye kongiri. Iwo mapolymer particles anoderedza kukweshera kwemukati pakati peaggregates uye binder, zvichiita kuti musanganiswa uve nyore kusanganisa, kutakura, uye kushandisa. Izvi zvinonyanya kubatsira mumapurojekiti ekuvaka akaomarara kana akaomarara uko nyore kushandisa kwakakosha.
Enhanced Adhesion:
Imwe yemabhenefiti ekutanga eRDP kugona kwayo kuvandudza zvakanyanya kunamatira kwedhaka kune akasiyana substrates. Izvi zvinonyanya kukosha mumashandisirwo akaita sematairi anonamira, madhiri ekugadzirisa, uye ekunze ekupisa kwekushisa masisitimu. Iyo firimu repolymer rakagadzirwa neRDP rinowedzera nzvimbo yekubatana uye simba rekubatanidza pakati pedhaka uye substrate.
Kuwedzera Flexibility uye Deformation Resistance:
Kongiri uye musanganiswa wedhaka une RDP unoratidza yakagadziridzwa kuchinjika uye deformation kuramba. Iyo firimu repolymer mukati mekongiri matrix inopa dhigirii rekuchinja rinobatsira zvinhu kutsungirira kushushikana uye madhiri pasina kuputika. Izvi zvinonyanya kukosha munzvimbo dziri pasi pekuwedzera kwekupisa, kuita kwekudengenyeka kwenyika, kana ma mechanical vibrations.
Kuramba Mvura uye Kusimba:
Iko kuiswa kweRDP kunosimudzira kuramba kwemvura kwedhaka uye kongiri. Iyo firimu yepolymer inoshanda sechivharo, ichideredza kupinda kwemvura uye zvinhu zvinokuvadza semakloridi uye sulfates. Ichi chivakwa chakakosha kune zvivakwa zvakafumurwa kune yakaoma mamiriro ekunze kana makemikari nharaunda, sezvo ichiwedzera hupenyu uye kusimba kwekongiri.
Mechanical Properties yakavandudzwa:
RDPs inobatsira kune iyo yakazara mechaniki simba rekongiri. Ivo vanovandudza kusimba uye kuchinjika simba, izvo zvakakosha pakuumbwa kwekuvimbika kwekongiri zvinhu. Kuwedzeredzwa uku kunokonzerwa nekusarudzika kuri nani kwekushushikana mukati mekongiri matrix inofambiswa neiyo polymer network.
Kuderedzwa kweShrinkage:
Duka uye kongiri musanganiswa neRDP inoratidza yakaderedzwa shrinkage uye kuputika. Iwo mapolymer particles anobatsira kudzora shrinkage inoitika panguva yekuomeswa nekuparadzira zvinonetsa zvakaenzana mukati mezvinhu. Izvi zvinoita kuti pave nekutsemuka kushoma uye chimiro chakanyanya kugadzikana.
Impact paKuitwa kweConcrete
Iko kuiswa kweRDP mumatope binder kongiri musanganiswa inoshandura zvakanyanya maitiro ekongiri, ichiita kuti iwedzere kuita zvinhu uye yakasimba. Nzvimbo dzekutanga dzekukanganisa dzinosanganisira:
Hurefu uye Kuchengetedza:
Zvimiro zvakagadzirwa neRDP-yakakwenenzverwa kongiri inowanzova nehupenyu hurefu hwesevhisi uye inoda kushomeka kwekugadzirisa. Iyo yakagadziridzwa kushorwa kumvura uye mhirizhonga yezvakatipoteredza inoreva kuti kongiri inochengetedza kuvimbika kwayo kwenguva yakareba, ichideredza kuwanda uye mutengo wekugadzirisa.
Zvezvakatipoteredza uye Zveupfumi:
Nekuwedzera hupenyu hwezvivakwa zvekongiri, maRDP anobatsira mukusimba mukuvaka. Kugadziriswa kushoma kazhinji uye kutsiva kunoreva kuderera kwekushandisa kwezvinhu uye simba pamusoro pehupenyu hwechivakwa. Pamusoro pezvo, iyo yakakwidziridzwa kushanda uye nekukurumidza nguva yekushandisa inogona kuderedza mutengo wevashandi uye nguva yekuvaka.
Aesthetic Hunhu:
MaRDPs anobatsira mukuwana kupera kwakapfava uye kunaka kwepamusoro mukongiri. Izvi zvinonyanya kukosha mumashandisirwo ekuvaka uko aesthetics yakakosha sekuita kwemaitiro. Iko kugona kugadzira-isina kuputika, nzvimbo dzakatsetseka dzinowedzera kukwezva kwekuona kweakapedzwa zvimiro.
Specialized Applications:
Iko kuita kwakasiyana-siyana kweRDP-inokwidziridzwa kongiri inoita kuti ive yakakodzera kune akasarudzika maapplication akadai seyepamusoro-kuita kugadzirisa, nhete-layer application, uye yakaoma geometries. Iyo inonamira yakawedzera uye inochinjika zvivakwa inobvumira hunyanzvi hwekuvaka uye zvigadziriso zvisingagoneke nemisanganiswa yechinyakare kongiri.
Zvidzidzo Zvenyaya uye Zvishandiso Zvinoshanda
Kuti unzwisise zvinobatika zveRDP mudhaka binder kongiri musanganiswa, zvinobatsira kufunga chaiwo nyaya dzezvidzidzo uye mashandisiro:
Tile Adhesives:
RDP inoshandiswa zvakanyanya mumatairi adhesive formulations. Iyo yakagadziridzwa yekunamatira uye kuchinjika inopihwa neRDP inovimbisa kuti mataira anoramba akasungwa zvakachengeteka kune substrates, kunyangwe munzvimbo dziri pasi pehunyoro uye kushanduka kwekushisa.
Gadzirisa Madhaka:
Mukugadzirisa madhaka, RDP inokwidziridza kubatana kwedhaka nyowani kune yekare kongiri, kuve nechokwadi chekugara uye kugadzirisa isina musono. Iko kuchinjika uye kushomeka kuramba kwakapihwa neRDP kwakakosha kuchengetedza kutendeseka kweakagadziridzwa zvimiro.
External Thermal Insulation Systems (ETICS):
RDP chinhu chakakosha muETICS, kwainobatsira kusungira zvinhu zvekudzivirira kumadziro ekunze uye inovandudza kuita kwese kweiyo insulation system. Iyo inonamira inonamira uye inodzivirira mamiriro ekunze inovimbisa kushanda kwenguva refu kweiyo insulation.
Redispersible Polymer Powders inoita basa rakakosha mune yemazuva ano dhaka binder kongiri musanganiswa. Kugona kwavo kukwidziridza kushanda, kunamatira, kuchinjika, kuramba mvura, uye michina zvimiro zvinoita kuti zvive zvakakosha mukushandisa kwakasiyana siyana kwekuvaka. Nekuvandudza kusimba uye kuita kwekongiri, maRDP anobatsira mukurebesa uye kusimba kwezvivakwa, zvichipa zvese zvakanaka zvehupfumi uye kwezvakatipoteredza. Sezvo tekinoroji yekuvaka ichifambira mberi, basa reRDP rinogona kuwedzera, richigadzira nzira yezvimwe zvinhu zvitsva uye zvinosimba zvekuvaka.
