Kuwedzera Kushanda Kwemiti Yakatetepa & Grout
Upfu hwepolymer hunosanganiswazve (RDP) chinhu chinoshandiswa zvakasiyana-siyana, chinoita firimu chinoshandura mashandiro emamota emataira negrouts. Nekushanda sechikamu chechipiri chekubatanidza, RDP inowedzera simba rekubatanidza kune substrates, inowedzera kusununguka kudzivirira kutsemuka, inovandudza kuchengetedza mvura kwenguva yakareba yakavhurika, uye inovandudza rheology kuti ishandiswe zviri nyore.
Upfu hwepolymer hunonyungudika hunogadzirwa nekupfapfaidza-kuomesa emulsion polymer—kazhinji vinyl acetate–ethylene (VAE) kana acrylic—kuita upfu hunoyerera huchidzokera ku polymer emulsion yakagadzikana kana yasangana nemvura. Mumasisitimu akavakirwa pa simende, aya ma polymer films matsva anobatana nezvigadzirwa zve hydration kugadzira network yakasimba, inochinjika inowedzera mashandiro akawanda.
Kushanda kweRDP muThin-Set Mortars
1. Kunamatira Kwepamusoro
RDP inoshanda sechikamu chechipiri chekubatanidza pamwe chete nesimende, ichivandudza zvakanyanya simba rekubatanidza kune zvinhu zvakaita sekongiri, bhodhi resimende, uye gypsum backerboard—zvichideredza njodzi dzekubvisa mataira kunyangwe kana paine kushushikana kwekupisa kana kwemagetsi.
2. Kuchinjika Kwakawedzerwa & Kuramba Kutsemuka
Firimu repolymer rinoita kuti simbi yemortar matrix irambe yakapfava, zvichiita kuti simbi iyi ikwanise kufamba nesubstrate uye kuwedzera kupisa pasina kutsemuka.
3. Kuchengetedzwa Kwemvura Kwakavandudzwa Uye Nguva Yakavhurika
Nekuderedza mwero wekurasikirwa nemvura panguva yekuisa, madhaka akagadziriswa neRDP anoramba achishanda kwenguva yakareba, zvichibvumira vanoisa nguva yakawanda yekukwesha trowelling nekugadzirisa mataira.
4. Kurapwa kweRheology & Sag Resistance Yakagadziridzwa
RDP inovandudza maitiro emota ye thixotropic—zvichiita kuti ive musanganiswa wakanaka, usingatsvedze unonamatira zvakanaka pamadziro nepadenga usingatsvedzemuki.
Kushanda kweRDP muGrouts
1. Zvisungo Zvakasimba, Zvinogara Nguva Yakawanda
Mumagrout anosimbisa simende, RDP inosimbisa kunamira pamipendero yemataira nepamipendero yemajoini, ichideredza kutadza kwegrout uye inovandudza kusimba kwemajoini ese.
2. Kuderedzwa kweStrict & Kutsemuka
Network yepolymer inoderedza kuoma kwevhu, zvichiita kuti mapuranga egrout asatsemuke uye arambe achitaridzika zvakafanana nekufamba kwenguva.
3. Kudzivirira Mvura & Mavara Kwakawedzerwa
Magirafu akagadziriswa neRDP haana maburi akawanda, zvichipa hunyoro hwakanyanya uye haakwanise kusvibiswa munzvimbo dzakanyorova dzakadai semashawa nemadziva emvura.
4. Nyore Kushandisa & Kuchenesa
Kugadziriswa kwepurasitiki uye kugadzikana kwakawedzerwa kunoita kuti magirafu akagadziriswa neRDP ave nyore kushandisa uye kuchenesa, zvichikurumidzisa kuiswa uye kuwedzera kunaka kwekupera.
Kusarudza RDP Yakakodzera
- Rudzi rwePolymer: Sarudza maRDP akavakirwa paVAE kuti unamate zvakanaka uye ugone kuchinjika; maRDP eacrylic anoshanda zvakanaka mukushanda kwepamusoro-soro kana kunze.
- Nhungamiro yeKupimirwa Kwemushonga: Mwero wekushandiswa kwechinhu ichi unobva pa4–8 kg pa 100 kg yedhaka rakaoma kana grout, asi kugadziriswa kwacho kunokurudzirwa kuburikidza nemiedzo yekurabhoritari.
- Hunhu & Kutevedzera Mutemo: Iva nechokwadi chekuti mutengesi weRDP anochengetedza mitemo yakasimba yekugovera zvidimbu uye anosangana nezvinodiwa neindasitiri (ANSI A118.4/A118.11 ye thinsets, ANSI A118.6 ye grouts).
- Rutsigiro rwehunyanzvi: Batana nevagadziri vanopa rubatsiro rwekugadzira, ruzivo rwekushanda, uye rutsigiro panzvimbo kuti vagadzirise misanganiswa yenyu.
Kuisa RDP yepamusoro-soro mumamortars negrouts zvakati sandara kwakakosha kuti pave nekuisa kwakasimba, kunochinjika, uye kusingapindi mvura. Nekunzwisisa mashandiro eRDP—kubva pakunamatira uye kuchinjika kusvika kurheology uye kuchengetedza mvura—nyanzvi dzeindasitiri dzinogona kusarudza chiwedzerwa chepolymer chakakodzera uye chiyero kuti chienderane nezvinodiwa zvepurojekiti uye kupa kushanda kwenguva refu. Kuti uwane mhinduro dzeRDP dzakagadzirirwa iwe uye nhungamiro yakadzama yehunyanzvi, bvunza mugadziri weRDP ane mukurumbira nhasi.
