I-Redispersible Polymer Powder (RDP) idlala indima ebalulekileyo kwizinto zokwakha zale mihla, ngakumbi kwiikhompawundi zokuzilinganisa. Ezi khompawundi, zibalulekile ekulungiseni agudileyo kunye neesubstrates, zixhamla kakhulu ekuqukweni kweRDP.
Uqulunqo neePropati zeRDP
I-RDP ithathwe kwiipolymers ezifana nevinyl acetate, ethylene, kunye ne-acrylics. Inkqubo ibandakanya ukutshiza-ukumisa i-emulsion yamanzi ukuze wenze ipowder enokuthi iphinde iphinde iphinde ibuyele emanzini, yenze i-emulsion ezinzileyo. Iimpawu eziphambili ze-RDP ziquka ukukwazi kwayo ukuphucula ukubambelela, ukuguquguquka, kunye nokuchasana kwamanzi kwizinto zokwakha.
Ukubunjwa kweMichiza: Ngokuqhelekileyo, ii-RDPs zisekelwe kwi-vinyl acetate-ethylene (VAE) copolymers. Ezi polymers zaziwa ngolungelelwaniso lwazo phakathi kokuguquguquka kunye namandla, zizenza zilungele usetyenziso olwahlukeneyo lolwakhiwo.
IiPropati zoMmandla: I-RDP ibonakala njengomgubo ocolekileyo, omhlophe. Xa ixutywe namanzi, yenza i-latex enokuphucula iimpawu zemixube yesamente. Obu buchule bokubuyela kwifom ye-emulsion yokuqala ibalulekile kumsebenzi wayo kwiikhompawundi zokuzilinganisa.
Indima yeRDP kwiiCompounds zokuZilinganisa
Iikhompawundi zokuzilinganisa ziyimixube yesamente eyilelwe ukwenza umphezulu ogudileyo kunye nomgangatho ngaphandle komsebenzi omkhulu. Ukubandakanywa kwe-RDP kule mixube kuzisa uphuculo oluninzi:
Ukuhamba okuPhuculweyo kunye nokuSebenza: i-RDP iphucula i-rheology yomxube, iqinisekisa ukuhamba kakuhle kunye nokusasazeka. Le propati ibalulekile ekuphumezeni umgangatho womphezulu ngomzamo omncinci. Iinqununu ze-polymer zinciphisa ukungqubuzana kwangaphakathi ngaphakathi komxube, okuvumela ukuba uhambe ngokulula kwi-substrate.
Ukubambelela okongeziweyo: Enye yeendima eziphambili ze-RDP kukuphucula ukubambelela kwikhompawundi yokuziphakamisa kwii-substrates ezahlukeneyo. Oku kubaluleke kakhulu ekuqinisekiseni ukuba ikhompawundi yenza ibhondi eyomeleleyo kunye nomgangatho okhoyo, nokuba ukhonkrithi, ukhuni, okanye ezinye izinto. Iinqununu ze-polymer zingena kwi-substrate surface, ziphucula ukudibanisa komatshini kunye nokudibanisa kweekhemikhali.
I-Flexibility kunye ne-Crack Resistance: I-flexibility enikezelwa yi-RDP inceda ekuhlaliseni ukunyakaza kwe-substrate kunye nokwandiswa kwe-thermal, ngaloo ndlela kuncitshiswe amathuba okuqhekeka. Oku bhetyebhetye kunenzuzo ngokukodwa kwiindawo eziphantsi kokutshintsha kobushushu okanye ukunyakaza okuncinci, ukuqinisekisa ukuqina komphezulu osemgangathweni.
Ugcino lwaManzi: I-RDP iphucula ugcino lwamanzi kwikhompawundi ekwaziyo ukuzilinganisa. Oku kubalulekile ekuthinteleni ukulahleka kwamanzi ngokukhawuleza okunokukhokelela ekungangeni kakuhle kwamanzi kwisamente, okukhokelela kwindawo ebuthathaka kunye ne-brittle. Ugcino lwamanzi olongeziweyo luqinisekisa ukuba isamente iphilisa ngokufanelekileyo, ifumana amandla afanelekileyo kunye nokuqina.
Amandla oomatshini: Ubukho be-RDP bongeza iipropathi zoomatshini ezipheleleyo zekhompawundi yokuziphakamisa. Oku kubandakanya ukuphuculwa kokuqina kunye namandla oxinzelelo, okubalulekileyo kubomi obude kunye nokuthembeka kwesisombululo somgangatho. Ifilimu ye-polymer eyenziwe ngaphakathi kwe-matrix isebenza njenge-ejenti yokuqinisa, ukusabalalisa uxinzelelo kunye nokuphucula ukunyaniseka kwesakhiwo.
Indlela yokwenza
Ukusebenza kwe-RDP kwiikhompawundi zokuzilinganisa kunokuqondwa ngendlela yayo yokusebenza:
Ukuqulunqwa kwefilimu: Emva kokufakwa kwamanzi kunye nokomisa, amaqhekeza e-RDP adibanisa ukwenza ifilimu yepolymer eqhubekayo ngaphakathi kwe-matrix ye-cementitious. Lo mboniso bhanyabhanya usebenza njengesibophelelo esiguquguqukayo nesinamandla esibambe i-matrix kunye, iphucula ubumbano ngokubanzi.
I-Packing Packing: I-RDP iphucula ukupakisha ukuxinana kweengqungquthela kwi-self-leveling compound. Oku kukhokelela kwi-microstructure edibeneyo kunye nexineneyo, ukunciphisa i-porosity kunye nokwandisa amandla.
I-Interfacial Bonding: I-polymer chain chain ye-RDP idibanisa kunye neemveliso ze-cement hydration, ukuphucula i-interfacial bonding phakathi kwamacandelo e-cementitious kunye ne-aggregate particles. Oku kudityaniswa okuphuculweyo kunegalelo ekusebenzeni ngcono koomatshini kunye nokuqina.
Izicelo kunye neeNzuzo
Ukudityaniswa kwe-RDP kwiikhompawundi zokuzilinganisa zifumana izicelo kwiimeko ezahlukeneyo:
