I-Redispersible polymer powder (RDP) iyisengezo esibalulekile ezintweni zokwakha zesimanje, ikakhulukazi ezintweni zokunamathisela, osimende, namapulasi.Ngokuthuthukisa izici ezibonakalayo namakhemikhali zalezi zinsiza, ama-RDP adlala indima ebalulekile ekwenzeni ngcono ukuqina nokusebenza kwamaphrojekthi wokwakha.
Ukubunjwa kanye Nendlela Ye-RDP
I-RDP ikhiqizwa ngokufafaza i-emulsion yezinto ze-polymeric, ngokuvamile esekelwe ku-vinyl acetate-ethylene (VAE), i-acrylic, noma i-styrene-butadiene.Le nqubo iguqula i-emulsion ibe impushana enhle engaphinde ihlakazwe emanzini, iphinde ihlanganise ukuhlakazeka kwe-polymer yasekuqaleni.Uma yengezwa ezixubeni zodaka olomile, i-RDP iphinde isebenze lapho ithintana namanzi, idale ifilimu elinganayo futhi ezinzile ngaphakathi kwe-adhesive matrix.
Ukuthuthukisa Ukumelana Namanzi
Ukwakhiwa Kwefilimu: Lapho i-hydration, izinhlayiya ze-RDP ziyahlangana ukuze zenze ifilimu ye-polymer eqhubekayo kuyo yonke i-matrix enamathelayo.Le filimu isebenza njengesithiyo, inciphisa kakhulu i-porosity kanye nokungena kwamanzi kwe-adhesive.Ifilimu ivimba iziteshi ze-capillary, ivimbele ukungena kwamanzi futhi ithuthukise ikhono lokunamathisela eliphelele lokuvimbela amanzi.
Izakhiwo Ze-Hydrophobic: Amafomu amaningi e-RDP ahlanganisa ama-ejenti noma izilungisi ze-hydrophobic ezithuthukisa ukumelana kwamanzi.Lezi zingxenye ze-hydrophobic zinciphisa ukumuncwa kwamanzi kwe-adhesive, ziqinisekisa ukusebenza kwesikhathi eside ngisho nasezimweni ezimanzi.
Ukubumbana Okuthuthukisiwe Nokuguquguquka: I-RDP ithuthukisa ukuhlangana kwangaphakathi kwe-adhesive, ithuthukise amandla ayo ebhondi kanye nokuguquguquka.Lokhu kuvumelana nezimo kubalulekile ekuvimbeleni ukwakheka kwemifantu nezikhala ezingavumela amanzi ukuba angene.I-adhesive engakwazi ukuthwala ukunwetshwa nokufinyela okushisayo ngaphandle kokuqhekeka igcina ubuqotho bayo nokumelana namanzi ngokuhamba kwesikhathi.
Ukuthuthukisa Ukumelana Nesimo Sezulu
Ukuzinza kwe-UV: Amafomu e-RDP ngokuvamile aklanyelwe ukumelana nokuwohloka okuvela ekukhanyeni kwe-ultraviolet (UV).Ifilimu ye-polymer eyakhiwe yi-RDP izinzile nge-UV, ivikela ingcina engaphansi emiphumeleni eyingozi yokuchayeka elangeni isikhathi eside.Lokhu kuzinza kuqinisekisa ukuthi ingcina igcina amandla nokunwebeka kwayo ngisho nangemva kokuchayeka elangeni isikhathi eside.
I-Thermal Resistance: Izinto zokwakha zingaphansi kokuhlukahluka kwezinga lokushisa okwedlulele, okungabangela ukunwetshwa nokuncipha.Izinamathiselo ezilungiswe nge-RDP zibonisa ukumelana nokushisa okuhle kakhulu, zigcina amandla azo ebhondi kanye nokuguquguquka kulo lonke izinga lokushisa elibanzi.Lesi sici sivimbela okunamathelayo ekubeni brittle esimweni sezulu esibandayo noma ukuthamba ngokweqile ezimweni ezishisayo, ngaleyo ndlela kuthuthukise ukumelana nesimo sezulu.
Ukumelana Nemijikelezo Yokuncibilika Kweqhwa: Ezimweni ezibandayo, izinto ezisetshenziswayo ziba nemijikelezo yokuncibilika ephindaphindwayo, engaba yingozi kakhulu.Ukuvumelana nezimo nokuhlangana okuhlinzekwa yi-RDP kusiza okunamathelayo ukumelana nale mijikelezo ngaphandle kokulahlekelwa ubuqotho.Ifilimu ye-polymer isebenza njengento ebamba ukushaqeka, inciphisa izingcindezi ezibangelwa ukuqhwa nokuncibilika.
Izicelo Ezisebenzayo
I-Exterior Insulation and Finish Systems (EIFS): I-RDP isetshenziswa kakhulu ku-EIFS, lapho ukumelana kwamanzi nesimo sezulu kubalulekile.I-polymer powder iqinisekisa ukuthi izingqimba zokunamathisela kulezi zinhlelo zingamelana nokungenwa komswakama futhi zimelane nezimo zezulu ezishintshayo, zivikele ubuqotho besakhiwo kanye nezakhiwo zokushisa zesistimu.
Okunamathiselwe Kwethayela namaGrouts: Kokubili izinhlelo zokusebenza zangaphakathi nangaphandle, okunamathelayo kwethayela nama-grouts alungiswe nge-RDP abonisa ukusebenza okuphezulu.Zimelana nokungena kwamanzi futhi zivimbela amathayili ukuthi angaxegi noma alimale ngenxa yesimo sezulu.Lokhu kubaluleke kakhulu ezilungiselelweni zangaphandle lapho amathayela echayeka emvuleni, kwisithwathwa, nasemingeni yelanga.
Lungisa Izinsimbi Nezinhlanganisela Zokunamathisela: Ukuze kulungiswe ukhonkolo nokuphetshwa, i-RDP ithuthukisa ukuqina kwezinto zokulungisa.Iqinisekisa ukuthi lezi zinto ezisetshenziswayo zibophezela ngempumelelo kukhonkolo ekhona, ihlinzeka ngesixazululo esingangeni manzi nesimelana nesimo sezulu esinweba isikhathi sokuphila sokulungiswa.
Izinzuzo Zemvelo kanye Nezomnotho
Ukuphila Okunwetshiwe: Ngokuthuthukisa ukumelana namanzi nesimo sezulu, i-RDP yelula isikhathi sokuphila sezinto ezinamathelayo zokwakha kanye nezakhiwo ezisetshenziswa kuzo. Lokhu kunciphisa isidingo sokulungiswa njalo nokushintshwa, okuholela ekwehleni kwezindleko zokulungisa nokusetshenziswa kwezinsiza.
Ukusebenza Kahle Kwezamandla: Ezinhlelweni ezifana ne-EIFS, izinto zokunamathisela ezithuthukisiwe ze-RDP zifaka isandla ekusebenzeni okungcono kokwahlukanisa ngokugcina ubuqotho besistimu yokuhlukanisa.Lokhu kungaholela ekongeni amandla okubalulekile ekushisiseni nasekupholiseni izakhiwo, okukhuthaza ukusimama.
Udoti Oncishisiwe: Ukusetshenziswa kwezinamatheliso ezihlala isikhathi eside, ezimelana nesimo sezulu kunciphisa udoti wokwakha okhiqizwa izinto ezihlulekile noma ezonakele.Lokhu kufaka isandla ezenzweni zokwakha ezisimeme futhi kunciphisa umthelela wemvelo wamaphrojekthi wokwakha.
I-polymer powder e-redispersible iyisengezo esishintshayo ekunamatheleni okwakhiwa, esinikeza amanzi abalulekile kanye nezakhiwo zokumelana nesimo sezulu.Ikhono layo lokwenza ifilimu ye-polymer evikelayo, ehambisana nezici ze-hydrophobic kanye nokuguquguquka okuthuthukisiwe, kwenza izinto zokunamathisela eziguqulwe i-RDP ziqine ngokumelene nezinselele zomswakama kanye nokuchayeka kwesimo sezulu.Ngokuhlanganisa i-RDP ezintweni zokwakha, abakhi nonjiniyela bangaqinisekisa ukuthi izakhiwo ezihlala isikhathi eside, ezihlala isikhathi eside ezihlome kangcono ukumelana nezingcindezi zemvelo.Lokhu akugcini nje ngokuthuthukisa ukusebenza nokuthembeka kwamaphrojekthi wokwakha kodwa futhi kukhuthaza ukusimama kanye nokuphumelela kwezindleko embonini.
