Okuqukethwe komlotha we-redispersible polymer powders (RDP) iyipharamitha ebalulekile ethinta kakhulu ukusebenza kwabo ezinhlelweni ezihlukahlukene, ikakhulukazi embonini yokwakha.Nakuba umuntu engase acabange ukuthi okuqukethwe komlotha ophansi kungcono, kubalulekile ukuqonda indima edlalwa umlotha ezimpahleni nasekusebenzeni kwe-RDP.
Funda mayelana ne-Redispersible Polymer Powder (RDP):
I-RDP iyipolymer yokwenziwa eyimpuphu eyakha ifilimu efana ne-polymer yasekuqaleni uma ixutshwe namanzi.Isetshenziswa kabanzi ezinhlelweni zokwakha ezifana nodaka nokhonkolo ukuthuthukisa izakhiwo zabo.I-RDP isuselwa ku-emulsion polymerization yezinhlobonhlobo zama-monomers, kufaka phakathi i-vinyl acetate, i-ethylene nama-acrylates.
Incazelo yokuqukethwe komlotha:
Okuqukethwe komlotha kusho insalela ye-inorganic eshiywe ngemuva kokushiswa kwesampula.Ku-RDP, okuqukethwe komlotha kuvame ukuhlotshaniswa nokuba khona kwamaminerali asele nezinye izakhi ze-inorganic ku-polymer.Ukunqunywa kokuqukethwe komlotha kubalulekile njengoba kuthinta ukusebenza kwe-polymer mayelana nokuhlakazeka, ukwakheka kwefilimu kanye nekhwalithi iyonke.
Okuqukethwe komlotha okuphansi: izinzuzo
Thuthukisa ukuhlakazwa:
Okuqukethwe komlotha okuphansi ngokuvamile kuhlotshaniswa nokuhlakazeka okungcono emanzini.Lokhu kubalulekile ku-RDP njengoba idinga ukwakha ukuhlakazeka okuzinzile lapho kuxutshwe namanzi ukuze kuqinisekiswe ukusatshalaliswa okulinganayo ngaphakathi kodaka noma ingxube kakhonkolo.
Thuthukisa ukwakheka kwefilimu:
Okuqukethwe komlotha ophansi kusiza ukwakha ifilimu efanayo futhi eguquguqukayo.Lokhu kusiza ukuthuthukisa ukunamathela nokuhlangana kwempahla yokugcina yokwakha.
Yehlisa isidingo samanzi:
Ama-RDP anomlotha omncane angase adinge amanzi amancane ukuze aphinde ahlakazwe.Lokhu kunenzuzo ekwenziweni lapho okuqukethwe kwamanzi kudinga ukuncishiswa ukuze kuzuzwe izici ezibonakalayo ezifiselekayo.
Izakhiwo zemishini ezithuthukisiwe:
Okuqukethwe komlotha ophansi kungase kube nomthelela ezinhlelweni ezingcono zemishini yempahla yokugcina yokwakha.Lokhu kuhlanganisa amandla okubamba athuthukisiwe, ukuguquguquka nokuqina.
Yehlisa isimo sezulu:
I-efflorescence, ukufakwa kukasawoti oncibilikayo ebusweni bento, ingancishiswa ngokuqukethwe komlotha okuphansi.Lokhu kubalulekile ekugcineni ubuhle nobuqotho besakhiwo sezinto zokwakha.
Okuqukethwe komlotha okuphezulu: ukucatshangelwa
Izindleko zokucatshangelwa:
Izinqubo zokukhiqiza ezifinyelela okuqukethwe komlotha ophansi zingase zibe nezindleko zokukhiqiza eziphakeme.Ngakho-ke, kukhona ukuhwebelana phakathi kokuzuza ukusebenza okudingekile kanye nokuphumelela kwezindleko.
Ukucaciswa kohlelo lokusebenza:
Ngokuya ngohlelo lokusebenza, okunye ukwakheka kungabekezelela okuqukethwe komlotha okuphezulu ngaphandle kokuphazamisa ukusebenza.Kulokhu, ukuhlaziywa kwezindleko zenzuzo kubalulekile ekunqumeni okuqukethwe komlotha okwamukelekayo.
Ukuthobela Umthetho:
Izifunda ezihlukene zingaba nemithethonqubo ethile noma izindinganiso zokuqukethwe komlotha okuvunyelwe okuphezulu kwezinto zokwakha.Ukubambelela kulawa mazinga kubalulekile ekwamukelweni kwemakethe.
Ukuthuthukisa nokulawula ikhwalithi:
Ukuze uthole ibhalansi elungile phakathi kwezinzuzo kanye nemikhawulo engaba khona yokuqukethwe komlotha ophansi, abakhiqizi bavamise ukuzibandakanya ezinqubweni zokuthuthukisa nekhwalithi.Lezi zinqubo zibandakanya ukulungisa izimo ze-polymerization, kusetshenziswa izinto ezingavuthiwe zekhwalithi ephezulu, nokusebenzisa amasu okuhlanza asebenzayo.
Ekuphetheni:
Nakuba okuqukethwe komlotha ophansi ku-RDP ngokuvamile kunikeza izinzuzo ezimbalwa, izidingo ezithile zohlelo oluhlosiwe kufanele zicatshangelwe.Okuqukethwe komlotha okuhle kungahluka kuye ngezinto ezifana nezakhiwo ezidingekayo zempahla yokwakha, ukucatshangelwa kwezindleko kanye nezidingo zokulawula.Abakhiqizi kufanele balinganisele ngokucophelela lezi zici ukuze bakhiqize i-RDP yekhwalithi ephezulu ehlangabezana nezidingo ezihlukahlukene zemboni yezokwakha.Ukuqonda okuphelele ukusebenzisana phakathi kokuqukethwe komlotha nezakhiwo ze-RDP kubalulekile ekuqinisekiseni impumelelo yephrojekthi yokwakha kanye nobude bezinto ezisetshenziswayo.
