Impuphu ye-polymer ephinde ihlakazeke (RDP)iyinto ebalulekile ye-polymer yemvelo, esetshenziswa kabanzi emikhakheni eminingi njengokwakha, izinto zokwakha, ukuhlobisa kanye nezimboni. Ngokuyinhloko iyimpuphu egeleza ngokukhululeka etholakala ngama-emulsion okomisa ngokufutha (njenge-vinyl acetate-ethylene copolymers, i-vinyl acetate-acrylate copolymers, njll.). Le mpuphu ingasakazwa futhi ukuze yakhe i-emulsion eqinile ngemva kokuxubana namanzi, ngaleyo ndlela igcine ukusebenza kwe-emulsion yokuqala.
1. Izici eziyisisekelo
Impuphu ye-polymer ephinde ihlakazeke inezici ezilandelayo ezibalulekile:
Ukuphinde kuhlakazeke kahle kakhulu: Kungaphinde kuhlakazeke ngokushesha kube sesimweni sokuqala se-emulsion emanzini, okwenza kube nokusebenza okuhle kokwakhiwa.
Ukusebenza kahle kakhulu kokubopha: Thuthukisa amandla okubopha phakathi kwezinto zokwakha kanye ne-substrate.
Thuthukisa ukuguquguquka: Thuthukisa ukumelana kokuqhekeka kwezinto futhi kufanelekile kwezinye izinhlelo zokusebenza ezidinga ukuguquguquka okuphezulu.
Ukumelana namanzi kanye nokumelana ne-alkali: Kusazinzile ezindaweni ezine-alkali njengesamente noma i-lime.
Ukulwa nokuguga kanye nokumelana nesimo sezulu: Kusaqhubeka nokusebenza kahle ngaphansi kwemisebe ye-ultraviolet noma izimo zezulu ezinzima.
2. Ukusetshenziswa okuyinhloko
I-adhesive yethayela kanye ne-adhesive esekela ithayela I-Redispersible polymer powder isetshenziswa kabanzi kwi-adhesive yethayela. Ithuthukisa ukuguquguquka kanye namandla okubopha kwezinto zokunamathisela ithayela, okuvumela amathayela ukuthi aboshwe ngokuqinile ezindaweni ezahlukahlukene, ikakhulukazi ezifanele amathayela amakhulu, angamuncwi amanzi amaningi.
Impuphu ye-putty kanye ne-putty yangaphandle yodonga Ukwengeza i-polymer powder ephinde ihlakazeke ku-putty yangaphakathi nangaphandle yodonga kungathuthukisa kakhulu ukunamathela, ukumelana namanzi kanye nokusebenza kokwakhiwa kwe-putty. Ikakhulukazi ekusetshenzisweni kodonga lwangaphandle, ukumelana nesimo sezulu okuthuthukisiwe kudlala indima ebalulekile ekuvimbeleni ukuchitheka nokuqhekeka kwempuphu.
Izinto zokwakha phansi ezizilinganisayo Iphansi likasimende elizilinganisayo lidinga ukugeleza okuhle nokunamathela. Impuphu ye-polymer ephinde ihlakazeke ingathuthukisa ukulula kwayo ekwakheni kanye nezakhiwo zokwakha ifilimu, futhi inciphise ukuqhekeka kanye nokwehlukaniswa.
Uhlelo lwe-insulation mortar (njenge-EIFS yangaphandle odongeni uhlelo lokufaka i-insulation) Ukwengeza i-Redispersible polymer powder ku-insulation mortar kungathuthukisa ukunamathelana phakathi kwe-mortar ne-substrate (njenge-foam board, i-polystyrene board, njll.), kuthuthukise ukumelana nokuqhekeka, ukumelana neqhwa futhi kwandise impilo yesistimu.
Udaka olungangeni manzi Ukusebenzisa i-RDP kwifomula yodaka olungangeni manzi kungathuthukisa kakhulu ukuguquguquka nokungangeni kwamanzi kwezinto, ukuze ikwazi ukugcina ukusebenza kwayo endaweni enomswakama nehlala isikhathi eside yokuxhumana namanzi.
Ukulungisa i-mortar kanye ne-interface agent I-powder ye-polymer ephinde ihlakazeke ingathuthukisa ukunamathela kanye nokuqina kwe-mortar yokulungisa ukuze kugwenywe imifantu endaweni elungisiwe. Ukwengeza i-RDP ku-interface agent kungathuthukisa amandla okubopha phakathi kwezingqimba ezahlukene zezinto.
Izinto ezisekelwe ku-gypsum Ukusebenzisa i-Redispersible polymer powder ezingqimbeni zokulinganisa ezisekelwe ku-gypsum kanye nezihlanganisi ze-gypsum kungathuthukisa amandla azo okubopha, ukumelana nokuqhekeka kanye nokusebenza kokwakhiwa, futhi kuyingxenye ebalulekile yezinto zokwakha eziluhlaza.
3. Izinzuzo zohlelo lokusebenza
Ukwakhiwa okulula Impuphu ye-polymer ephinde ihlakazeke ivame ukuba sesimweni sempuphu eyomile futhi ingaxutshwa ngqo nezinye izinto ezomile (njengesimende, isihlabathi, njll.) ngaphandle kokwelashwa okwengeziwe kwe-emulsification. Ingasetshenziswa endaweni ngokungeza amanzi, okulula ukuthuthwa nokwakhiwa.
Thuthukisa ukusebenza okuphelele Akugcini nje ngokuthuthukisa ukusebenza kokubopha kwe-mortar, kodwa futhi kuthuthukisa izakhiwo zayo eziphelele zomzimba njengokumelana nokuqhekeka, ukumelana nesithwathwa, ukumelana nokuguguleka kanye nokuguquguquka. Kuyisithasiselo esibalulekile sokuthuthukisa ikhwalithi yezinto zokwakha.
Ukuvikelwa nokuphepha kwemvelo Impuphu ye-polymer ephinde ihlakazeke ayinabo ubuthi futhi ayinangozi, ihlangabezana nezidingo zezakhiwo zesimanje zokuvikela imvelo kanye nokukhishwa okuphansi kwe-VOC, futhi isetshenziswa kakhulu ezinhlelweni zezakhiwo eziluhlaza.
4. Izitayela zentuthuko yesikhathi esizayo
Njengoba isidingo esikhulayo sezinto zokwakha eziluhlaza nezinobungani nemvelo kanye nokusungulwa okusha okuqhubekayo kobuchwepheshe bokwakha, ifomula kanye nokusebenza kwempuphu ye-polymer e-Redispersible nakho kuyathuthukiswa, kuqhubekela phambili ekunamatheleni okuphezulu, ukumelana nesimo sezulu okuphezulu, kanye nokukhishwa kwe-VOC okuphansi. Ngesikhathi esifanayo, kuhlanganiswe nezinkambu ezintsha zezinto ezifana ne-nanotechnology nezinto ezisekelwe ku-bio, ukusetshenziswa okuqhubekayo nokusebenzayo kwe-RDP nakho kuzoba yindawo ebalulekile ocwaningweni nasekuthuthukisweni kwesikhathi esizayo.
Njengesengezo se-polymer esisebenzayo,I-RDPIdlala indima engenakuphindwa ezakhiweni zesimanje kanye nezinto zokwakha zezimboni ngenxa yokusebenza kwayo okuhle kakhulu kanye nobubanzi bezicelo. Kusukela ekugandayweni kwamathayili kuya ekulinganisweni kodonga, kusukela ekwakhiweni kwephansi kuya ekulungisweni okungangeni manzi, ihlose ukuthuthukisa ukusebenza kwezinto zokwakha kanye nokusebenza kahle kokwakha, futhi ikhuthaza yonke imboni yezinto zokwakha ukuthi iqhubekele emazingeni aphakeme kanye neziqondiso ezinobungani nemvelo.
