I-grouting yamatshe iyinto yokwakha ekhethekile esetshenziselwa ukugcwalisa izikhala zamatshe, ukuthuthukisa imiphumela yokuhlobisa kanye nokuqina kwesakhiwo, futhi idinga ukunamathela okuhle, ukumelana nokuqhekeka, ukumelana nesimo sezulu kanye nokumelana namanzi.Impuphu ye-polymer ephinde ihlakazeke (RDP)kuyingxenye ebalulekile eguquliwe kufomula ye-grouting yamatshe, engathuthukisa kakhulu ukusebenza kwezinto ze-grouting, okwenza ibonise ukuqina okungcono kanye nolwazi lokwakha kumaphrojekthi angaphakathi nangaphandle.
1. Izici eziyisisekelo kanye nendlela yokusebenza kwe-RDP
I-RDP iyimpuphu ye-polymer ephinde ihlakazeke elungiselelwe ngenqubo yokomisa ngesifutho. Izinto eziyisisekelo ezivamile zifaka i-ethylene-vinyl acetate (EVA), i-acrylate copolymer kanye ne-styrene-acrylate copolymer. I-RDP ingahlakazeka kabusha ukuze yakhe i-polymer emulsion lapho ihlangana namanzi, bese yakha ifilimu ye-polymer yenethiwekhi enemikhiqizo noma ama-filler esimende ukuze kuthuthukiswe ukuguquguquka kanye namandla okubopha aphelele ezinto zokugcoba. Ekugcobeni ngamatshe, le filimu ye-polymer ingakha "ibhuloho lokunamathela" ebusweni betshe, imelane ngempumelelo nokuhlushwa kokucindezeleka okubangelwa ukwanda nokuncipha kokushisa, futhi inciphise ingozi yokuqhekeka.
2. Thuthukisa ukunamathela nokumelana nokuqhekeka
I-grouting yamatshe ivame ukusetshenziselwa ukugcwalisa izikhala etsheni lemvelo, imabula, i-granite nezinye izinto. Lezi zingxenye zinezindawo ezixineneyo kanye nokumuncwa kwamanzi okuncane, futhi zinokunamathela okulinganiselwe ku-mortar evamile yesamente. Ngemva kokufaka i-RDP, ifilimu ye-polymer eguquguqukayo eyakhiwe ezintweni ze-grouting ithuthukisa kakhulu ukunamathela ne-substrate yamatshe, futhi ingagcina ukubopha okuhle ngisho nasendaweni enomehluko omkhulu wokushisa, ivimbele ukuqhekeka nokuwa. Ngesikhathi esifanayo, i-RDP inikeza izinto ze-grouting ukuqina okuthile, okunganciphisa ngempumelelo imifantu ebangelwa ukushwabana noma amandla angaphandle esibonakalayo setshe.
3. Thuthukisa ukumelana namanzi kanye nokungangeni kwamanzi
Izinto zokugaya amatshe zivame ukuba mhlophe, zigobe noma ziwe uma zivezwa endaweni enomswakama isikhathi eside. Ifilimu ye-polymer ehlanganisiwe eyenziwe yi-RDP ohlelweni lokugaya inganciphisa ama-capillary pores, ithuthukise ukungenwa kwezinto kanye nokumelana namanzi, ngaleyo ndlela ivimbele ngempumelelo umswakama ukuthi ungangeni ngaphakathi kwetshe. Lokhu kubaluleke kakhulu ekugayeni amatshe ezindaweni ezimanzi noma ezivezwe njengezindlu zangasese, amakhishi kanye nezindawo zangaphandle.
4. Thuthukisa ukusebenza kokwakha
Ukwethulwa kwe-RDP akugcini nje ngokuthuthukisa izakhiwo zemishini zezinto eziqediwe zokufaka i-grouting, kodwa futhi kuthuthukisa ulwazi lwayo lokwakha. I-RDP ingathuthukisa ukugcinwa kwamanzi kodaka futhi ivimbele ukuqhekeka okubangelwa ukulahleka kwamanzi kusenesikhathi; ngesikhathi esifanayo, ithuthukisa ukusebenza kahle kanye nokugeleza kwamanzi, okwenza kube lula ukuthi i-grouting igcwalise imifantu emincane futhi ifinyelele indawo ebushelelezi neyisicaba. Indawo yodaka ngemva kokwakhiwa kulula ukuyihlanza, kunciphisa ingozi yokungcolisa indawo yamatshe.
5. Thuthukisa ukumelana nesimo sezulu kanye nobuhle
Ngokusebenzisa i-grouting yamatshe angaphandle, ukumelana nokuguga kwe-UV kanye nokumelana nokuqandisa kuyizinkomba ezibalulekile zokulinganisa ukusebenza kwesikhathi eside. I-RDP inikeza izinto ze-grouting ukumelana nesimo sezulu okuhle kakhulu futhi ingagcina isakhiwo esizinzile ngaphansi kwezimo zokushisa eziphakeme neziphansi kanye nomjikelezo womjikelezo omanzi nowomile. Ngaphezu kwalokho, ukuguquguquka okuphezulu kwe-RDP kunganciphisa umehluko wombala noma ukuxebuka okubangelwa ukucindezeleka kwemvelo futhi kwandise ubuhle bomphezulu wetshe.
6. Umthamo we-RDP kanye nokwenza ngcono ifomula
Inani le-RDP ezintweni zokugaya amatshe kudingeka linqunywe ngokwezici ezifana nohlobo lwe-substrate, ububanzi bomthungo, kanye nendawo yokwakha, futhi ngokuvamile liyi-2% kuya ku-6% yesisindo sezinto ezisimende. Umthamo ophezulu kakhulu ungaholela ekuncipheni okukhulu kanye nezindleko eziphakeme, kuyilapho umthamo ophansi kakhulu ungase ungafinyeleli ukusebenza okulindelekile. Ngakho-ke, ekukhiqizweni kwangempela, kuyadingeka ukwenza ngcono ifomula ngokusebenzisa izivivinyo bese uyilungisa ngokuhambisana nezinye izithasiselo ezifana ne-cellulose ether, i-defoamer kanye ne-filler ukuze uthole umphumela omuhle kakhulu wokwakha nokusebenzisa.
Njengengxenye ebalulekile eguquliwe yezixazululo ze-grouting zamatshe,I-RDP ingathuthukisa ngempumelelo ukunamathela, ukuguquguquka, ukumelana namanzi kanye nokumelana nesimo sezulu kwezinto zokugaya, futhi ithuthukise kakhulu ukusebenza kokwakhiwa kanye nekhwalithi yomkhiqizo oqediwe. Ukusetshenziswa kwayo etsheni lemvelo, imabula kanye negranite kungasiza ekwandiseni impilo yephrojekthi futhi kugcine ubuhle bokuqedwa kwetshe. Esikhathini esizayo, ngokuthuthukiswa kwe-RDP esebenza kahle futhi enobungani nemvelo, izixazululo ze-grouting zamatshe zizothuthukiswa kakhulu zibe namandla aphezulu, ukuncishiswa okuphansi kanye nokuqina kwesikhathi eside.
