Upfu hwePolymer Hunogona Kunyungudutswazve (RDP), sechinowedzerwa chakakosha chepolymer, chave chichishandiswa zvakanyanya mumakore achangopfuura mudry-mix mortar, tile adhesive, putty powder, plastering mortar, uye grout. Kushandiswa kwayo mu tile grout kunonyanya kukosha mukuvandudza simba re bond, kuchinjika, kuramba kutsemuka, uye kuramba mvura.
1. Maitiro Ekuita kweRDP
RDP ihupfu hunonyungudika hunobva mupolymer emulsion kuburikidza nespray drying process, hune hunhu hwe re-emulsification kana yasangana nemvura. Kana RDP ikaiswa mugrout, mvura painopwa panguva yekuvaka, RDP particles dzinonyungudika kuti dzigadzire continuous polymer film. Iyi polymer film inorukwa ne cement hydration products, ichigadzira "inorganic-organic composite system," zvichivandudza zvakanyanya hunhu hwe mechanical hwechinhu uye hunhu hwe interfacial bonding.
Munguva yekugayiwa kwegrout, firimu reRDP polymer rinogona kufukidza zvikamu zve filler, zvichivandudza kubatana kwe interfacial uye kuderedza maburi esystem yakavakirwa pa simende. Uyezve, zvikamu zvinochinjika mumamorekuru eRDP zvinopa grout mwero wakati we ductility uye kuramba kuchinjika, zvichidzivirira zvinobudirira kutsemuka kunokonzerwa nekuchinja kwetembiricha kana kuchinjika kwe substrate.
2. Kuvandudzwa kweRDP kweMashandiro eTile Grout
2.1. Kusimba Kwakavandudzwa kweBond
Chinodiwa chikuru chegrout yemataira kunamatira zvakanaka kumipendero yemataira nesubstrate. RDP inoumba firimu re organic polymer, zvichiita kuti kubatana pakati pegrout yakavakirwa pa simende nepamusoro pemataira kuve kwakasimba. Panguva imwe chete, polymer residue mushure mekunyoroveswa kweRDP inowedzera huwandu hweinterface layer, nokudaro zvichivandudza zvakanyanya simba regrout uye kugara kwenguva refu.
2.2. Kuchinjika Kwakawedzerwa uye Kuramba Kutsemuka
Magirafu echinyakare akagadzirwa nesimende anowanzo pwanyika kana aoma kana kuchinja tembiricha, zvichikanganisa runako uye kushanda kwekudzivirira mvura. Kuiswa kwezvikamu zvepolymer muRDP kunovandudza kuchinjika uye ductility yechinhu chacho, zvichibvumira jira regirafu kuti rigone kumira kushushikana uye kushanduka kusina kutsemuka, nokudaro richiwedzera hupenyu hwaro hwekushanda.
2.3. Kuvandudzwa kweKudzivirira Mvura uye Kusapinda Mvura
Firimu repolymer rinogara richigadzirwa neRDP rine mukana wepasi wekupinda, richidzivirira kupinda kwemvura uye richideredza kunyudzwa kwemvura. Hunhu uhwu hwakakosha zvikuru munzvimbo dzine hunyoro dzakadai sekicheni nedzimba dzekugezera, zvichidzivirira hunyoro kuti husapinde kumashure kwemataira kana pasi pevhu, zvichideredza njodzi yekuumbwa kwevhu uye kuvharika kwevhu.
2.4. Kuramba Kusviba Kwakawedzerwa uye Kuramba Mavara
RDP yepamusoro-soro inovandudza huwandu hwepamusoro pegrout, zvichiita kuti ive yakapfava, isingakwenye, uye inoderedza kunamira kwetsvina. Grout yakagadziriswa neRDP hainyanyi kuungana kana kuchinja ruvara panguva yekuchenesa zuva nezuva, zvichiita kuti irambe ichitaridzika zvakanaka kwenguva yakareba.
2.5. Kubudirira Kwekushanda Kwemashandisirwo
RDP inovandudza zvakanyanya kuyerera kwemvura mugrout, zvichiita kuti kuisirwa kuite nyore, kuve nyore kuzadza mipata, uye kuderedza maburi nemhepo. Panguva imwe chete, simba rayo rekuchengetedza mvura rinoderedza mwero wemvura musimende, zvichipa vashandi nguva yakawanda yekuisa simende uye kuvandudza kunaka kwekushandisa uye kushanda zvakanaka.
3. Kushanda kweRDP Application mumhando dzakasiyana dzeGrout
3.1. Grout Yakavakirwa paSimende
Kuwedzera RDP kune grout yakajairika yakagadzirwa nesimende kunowedzera kunamira uye kuramba kutsemuka, zvichiita kuti ive yakakodzera zvikuru pakugrouter mataira emadziro neepasi mukati nekunze.
3.2. Epoxy kana High-Performance Grout
Pamhando dzemagrout emhando yepamusoro anoda kuti jira rirambe richiramba kupfekwa zvakanyanya uye risingapindi mvura, RDP, semugadziri, inoshanda pamwe chete nemamwe maresini kuti iwedzere kuchinjika uye kunamira.
3.3. Grout ine ruvara
Hunhu hweRDP hwekugadzira firimu hunobatsira kuona kuti ruvara rwakafanana, hunosimbisa kugara kwenguva refu kwemavara, hunodzivirira kusiyana kwemavara uye kupenya, uye hunoita kuti magirau ane mavara awedzere kushongedza.
4. Kukosha kwekushandisa uye Maitiro ekuvandudza eRDP
Muchidimbu, kukosha kwekushandisa kweRDP mugrout yemataira kunonyanya kuratidzwa muzvinhu zvinotevera:
Kugadzikana Kwekushanda Kwechigadzirwa Kwakavandudzwa: Nekuvandudza kunamira, kudzivirira mvura, uye kuchinjika, grout inoramba ichishanda zvakanaka munzvimbo dzakasiyana.
Hupenyu Hwebasa Hwakawedzerwa: Kudzivirira kutsemuka uye kusakara, zvichideredza mari yekugadzirisa gare gare.
Kuvandudza ruzivo rwekuvaka uye kunaka kwechigadzirwa chapera: Kunovandudza kushanda zvakanaka uye kuchengetedza mvura, zvichideredza zvikanganiso zvekuvaka.
Kuenderana negwara rekugadzirwa kwezvinhu zvekuvaka zvakasvibira: RDP chinhu chisina zvinonyungudutsa, chine VOC shoma, chinosangana nezvinodiwa zvekuchengetedza nharaunda uye chinobatsira mukuvakwa kwemaitiro ekuvaka akasvibira.
Sezvo indasitiri yekushongedza zvivakwa ichifambira mberi ichienda kumabasa epamusoro, kuchengetedzwa kwezvakatipoteredza, uye runako, basa reRDP mukugadzira mataira richawedzera kukosha. Tsvagiridzo nekuvandudzwa mune ramangwana zvichatarisa pakugadzira masisitimu epolymer ane simba rekudzivirira mamiriro ekunze, mvura shoma, uye kunamatira kwakasimba kuti zvienderane nezvinodiwa zvekushandiswa mumamiriro ekunze akasiyana nemamiriro ekuvaka.
Sechinhu chinogadzirisa matombo ari pakati pe tile grout,RDPinogona kuvandudza zvakanyanya hunhu hwayo hwemakanika, kuramba kutsemuka, kudzivirira mvura kupinda, uye kushanda zvakanaka, zvichiita kuti ive chinhu chakakosha chekugadzira zvivakwa zvemhando yepamusoro. Kushandiswa kwayo kwakapararira hakungoiti kuti grout ishande zvakanaka chete asiwo kunopa rutsigiro rwakasimba pakugadzira zvinhu zvekuvaka zvakasvibira uye zvinochengetedza simba.
