I-Redispersible Polymer Powder (RDP) isivele igqama kakhulu embonini yezokwakha, ikakhulukazi ezixubeni zikakhonkolo ezihlanganisa udaka. Ukufakwa kwabo kuletha inqwaba yezinzuzo ezithuthukisa ukusebenza nokuqina kokhonkolo.
Izakhiwo Zamakhemikhali ze-RDP
Ama-RDP akhiwa ngokufafazwa kwe-emulsion ye-polymer, okuholela kumpushana ocolile ongaphinde uhlakazeke kalula emanzini. Ama-polymers asetshenziswa kakhulu afaka i-vinyl acetate-ethylene (VAE), ama-vinyl acetate copolymers, nama-acrylic copolymers. Lawa ma-polymers akhethwa ngenxa yezakhiwo zawo zokunamathela, ukuguquguquka, kanye nekhono lokuthuthukisa izici ezihlukahlukene zomzimba zodaka nokhonkolo.
Lapho exutshwa namanzi, ama-RDP abuyela esimweni sawo sokuqala se-polymer, enze ifilimu ye-polymer ngaphakathi kwe-matrix kakhonkolo. Le filimu inikeza izici eziningana ezizuzisayo, njengokunamathela okuthuthukisiwe, ukuguquguquka, nokumelana nezinto zemvelo. Ukwakheka kwamakhemikhali kwama-RDP kuyawavumela ukuthi asebenzisane ngokuphumelelayo nezinto zikasimende, okuthuthukisa kokubili izimo ezintsha neziqinile zodaka nokhonkolo.
Izinzuzo ze-RDP ku-Mortar Binder Concrete Mixtures
Ukusebenza Okuthuthukisiwe:
Ama-RDP athuthukisa ukusebenza kodaka nokhonkolo. Izinhlayiya ze-polymer zinciphisa ukungqubuzana kwangaphakathi phakathi kwama-aggregates kanye ne-binder, okwenza ingxube ibe lula ukuyixuba, ukuthuthwa, nokusetshenziswa. Lokhu kunenzuzo ikakhulukazi kumaphrojekthi wokwakha ayinkimbinkimbi noma ayinkimbinkimbi lapho ukusebenziseka kalula kubalulekile.
Ukunamathela Okuthuthukisiwe:
Enye yezinzuzo eziyinhloko ze-RDP yikhono layo lokuthuthukisa kakhulu ukunamathela kodaka kuma-substrates ahlukahlukene. Lokhu kubaluleke kakhulu ekusetshenzisweni okufana nokunamatheliswa kwamathayela, izinsimbi zokulungisa, kanye nezinhlelo zokuvikela ukushisa zangaphandle. Ifilimu ye-polymer eyenziwe yi-RDP inyusa indawo yokuxhumana namandla okubopha phakathi kodaka ne-substrate.
Ukwenyuka Ukuguquguquka Nokumelana Nokuguqulwa:
Izingxube zikakhonkolo nodaka eziqukethe i-RDP zibonisa ukuguquguquka okuthuthukisiwe nokumelana nokuguga. Ifilimu ye-polymer ngaphakathi kwe-matrix kakhonkolo ihlinzeka ngezinga lokuguquguquka elisiza okokusebenza ukuthi kumelane nezingcindezi kanye nobunzima ngaphandle kokuqhekeka. Lokhu kubaluleke kakhulu ezindaweni ezingaphansi kokunwetshwa kwezinga lokushisa, umsebenzi wokuzamazama komhlaba, noma ukudlidliza kwemishini.
Ukumelana Namanzi Nokuqina:
Ukufakwa kwe-RDP kuthuthukisa ukumelana kwamanzi nodaka nokhonkolo. Ifilimu ye-polymer isebenza njengesithiyo, inciphisa ukungena kwamanzi nezinto eziyingozi njengama-chloride nama-sulfate. Lesi sakhiwo sibalulekile ezakhiweni ezichayeka esimweni sezulu esibi noma endaweni yamakhemikhali, njengoba yelula isikhathi sokuphila kanye nokuqina kukakhonkolo.
Izakhiwo Zemishini Ethuthukisiwe:
Ama-RDP afaka isandla kuwo wonke amandla emishini kakhonkolo. Athuthukisa amandla okunyakazisa kanye nokuguquguquka, okubalulekile ekuqineni kwesakhiwo sezakhi zekhonkrithi. Lokhu kuthuthukiswa kungenxa yokusabalalisa kwengcindezi okungcono ngaphakathi kwe-matrix kakhonkolo okwenziwa inethiwekhi ye-polymer.
Ukunciphisa Ukuncipha:
Izingxube zodaka nokhonkolo ezine-RDP zibonisa ukuncipha nokuqhekeka. Izinhlayiya ze-polymer zisiza ukulawula ukushwabana okwenzeka phakathi nenqubo yokomisa ngokusabalalisa izingcindezi ngokulinganayo kuyo yonke into. Lokhu kubangela imifantu embalwa kanye nesakhiwo esizinze kakhudlwana.
Umthelela Ekusebenzeni Kokhonkolo
Ukufakwa kwe-RDP ezixubeni zikakhonkolo ze-mortar binder kushintsha kakhulu izici zokusebenza zikakhonkolo, kuyenze ibe nezinto ezihlukahlukene futhi iqine. Izindawo eziyinhloko zomthelela zihlanganisa:
Ukuphila Okude Nokunakekela:
Izakhiwo ezenziwe ngokhonkolo othuthukisiwe we-RDP zivame ukuba nezimpilo ezinde zesevisi futhi zidinga ukulungiswa okuncane. Ukumelana okuthuthukisiwe kwamanzi kanye nabahlaseli bemvelo kusho ukuthi ukhonkolo ugcina ubuqotho bayo isikhathi eside, unciphisa imvamisa kanye nezindleko zokulungisa.
Izinzuzo Zemvelo Nezomnotho:
Ngokwandisa isikhathi sokuphila sezakhiwo ezikhonkolo, ama-RDP afaka isandla ekusimameni ekwakhiweni. Ukulungiswa okuvamisile nokufakwa esikhundleni kusho ukusetshenziswa okuphansi kwezinto kanye namandla esikhathini somjikelezo wempilo wesakhiwo. Ukwengeza, ukusebenza okuthuthukisiwe kanye nezikhathi zokufaka izicelo ezisheshayo kunganciphisa izindleko zabasebenzi kanye nezikhathi zokwakha.
Ikhwalithi yobuhle:
Ama-RDP asiza ekufinyeleleni ukuqedwa okushelelayo kanye nekhwalithi engcono yendawo ekhonkolo. Lokhu kubaluleke kakhulu ezinhlelweni zezakhiwo lapho ubuhle bubaluleke njengokusebenza kwesakhiwo. Ikhono lokukhiqiza izindawo ezingena-crack, ezibushelelezi zithuthukisa ukukhanga okubonakalayo kwezakhiwo eziqediwe.
Izicelo Ezikhethekile:
Ukuhlukahluka kokhonkolo othuthukisiwe we-RDP kuyenza ifanelekele izinhlelo zokusebenza ezikhethekile ezifana nokulungiswa kokusebenza okuphezulu, izinhlelo zokusebenza ezinongqimba oluncane, namajiyometri ayinkimbinkimbi. Izakhiwo zayo zokunamathela ezithuthukisiwe nezivumelana nezimo zivumela amasu okwakha amasha nezisombululo ezingenakwenzeka ngezingxube zokhonkolo zendabuko.
Izibonelo kanye Nezicelo Ezingokoqobo
Ukuze uqonde imithelela engokoqobo ye-RDP ezixubeni zikakhonkolo ezihlanganisa i-mortar binder, kuyasiza ukucabangela izehlakalo ezithile kanye nezicelo:
Izinamathiselo zamathayela:
I-RDP isetshenziswa kakhulu ekwakhiweni kwe-adhesive tile. Ukunamathela okuthuthukisiwe nokuguquguquka okuhlinzekwa yi-RDP kuqinisekisa ukuthi amathayela ahlala eboshwe ngokuphephile kuma-substrates, ngisho nasezindaweni ezingaphansi komswakama kanye nokuguquguquka kwezinga lokushisa.
Lungisa izinsimbi:
Emabhodweni okulungisa, i-RDP ithuthukisa ukuhlangana kukasimende omusha kukhonkolo omdala, iqinisekisa ukulungiswa okuhlala isikhathi eside futhi okungenazihibe. Ukuvumelana nezimo nokumelana nokuqhekeka okuhlinzekwa yi-RDP kubalulekile ekugcineni ubuqotho bezakhiwo ezilungisiwe.
Amasistimu Wangaphandle Wokufakwa Kwe-Thermal (ETICS):
I-RDP iyingxenye ebaluleke kakhulu ku-ETICS, lapho isiza khona ukuhlanganisa into efakwayo odongeni lwangaphandle futhi ithuthukise ukusebenza okuphelele kohlelo lokufakwa ngaphakathi. Izinto zokunamathela ezithuthukisiwe kanye nezindawo ezimelana nesimo sezulu ziqinisekisa ukusebenza kahle kwesikhathi eside kwe-insulation.
I-Redispersible Polymer Powder idlala indima ebalulekile ezingxubeni zikakhonkolo zesimanjemanje ezihlanganisa udaka. Ikhono labo lokuthuthukisa ukusebenza, ukunamathela, ukuguquguquka, ukumelana namanzi, kanye nezakhiwo zemishini kubenza babaluleke kakhulu ezinhlelweni ezahlukene zokwakha. Ngokwenza ngcono ukuqina nokusebenza kokukhonkolo, ama-RDP afaka isandla ekuphileni isikhathi eside nasekusimameni kwezakhiwo, ezinikeza kokubili izinzuzo zomnotho nezemvelo. Njengoba ubuchwepheshe bokwakha buthuthuka, indima ye-RDP cishe izokhula, ivule indlela yezinto zokwakha ezintsha neziqinile.
