I-Redispersible Polymer Powder (RDP) idlala indima ebalulekile ezintweni zokwakha zesimanje, ikakhulukazi kumakhompiyutha azilinganisa wona. Lezi zinhlanganisela, ezibalulekile ekulungiseleleni ama-substrates abushelelezi, ahlomula kakhulu ekufakweni kwe-RDP.
Ukubunjwa kanye Nezakhiwo ze-RDP
I-RDP itholakala kuma-polymers afana ne-vinyl acetate, i-ethylene, nama-acrylics. Le nqubo ihilela ukufutha-ukomisa i-emulsion yamanzi ukuze udale impushana engaphinde ihlakazeke emanzini, yakha i-emulsion ezinzile. Izakhiwo ezibalulekile ze-RDP zihlanganisa ikhono layo lokuthuthukisa ukunamathela, ukuguquguquka, nokumelana namanzi ezintweni zokwakha.
Ukubunjwa Kwamakhemikhali: Ngokuvamile, ama-RDP asekelwe ku-vinyl acetate-ethylene (VAE) copolymers. Lawa ma-polymer aziwa ngokulinganisela kwawo phakathi kokuguquguquka namandla, okuwenza afanelekele izinhlelo zokusebenza ezihlukahlukene zokwakha.
Izakhiwo Zomzimba: I-RDP ngokuvamile ivela njengempushana ecolekile, emhlophe. Uma ixutshwe namanzi, yakha i-latex engathuthukisa izici zezingxube zikasimende. Leli khono lokubuyela esimweni salo se-emulsion sangempela libalulekile ekusebenzeni kwayo kuma-self-leveling compounds.
Iqhaza le-RDP kuma-self-Leveling Compounds
Izinhlanganisela zokuzilinganisa ziyinhlanganisela kasimende eklanyelwe ukudala izindawo ezibushelelezi nezisezingeni ngaphandle komsebenzi omkhulu. Ukufakwa kwe-RDP kulezi zingxube kuletha izithuthukisi eziningana:
Ukugeleza Okuthuthukisiwe Nokusebenza: I-RDP ithuthukisa i-rheology yengxube, iqinisekisa ukugeleza okungcono nokusabalala. Lesi sakhiwo sibalulekile ukuze uthole indawo esezingeni eliphezulu ngomzamo omncane. Izinhlayiya ze-polymer zinciphisa ukungqubuzana kwangaphakathi ngaphakathi kwengxube, zivumela ukuthi igeleze kalula phezu kwe-substrate.
Ukunamathela Okuthuthukisiwe: Enye yezindima eziyinhloko ze-RDP ukuthuthukisa ukunamathela kwenhlanganisela yokuzilinganisa kuma-substrates ahlukahlukene. Lokhu kubaluleke kakhulu ekuqinisekiseni ukuthi inhlanganisela yakha isibopho esiqinile nephansi elikhona, kungakhathaliseki ukuthi ukhonkolo, ukhuni, noma ezinye izinto. Izinhlayiya ze-polymer zingena ngaphansi kwe-substrate, zithuthukisa ukuhlangana kwemishini kanye nokubopha kwamakhemikhali.
I-Flexibility and Crack Resistance: Ukuvumelana nezimo okunikezwa yi-RDP kusiza ekwamukeleni ukunyakaza kwe-substrate kanye nokwanda okushisayo, ngaleyo ndlela kunciphisa amathuba okuqhekeka. Lokhu kuvumelana nezimo kunenzuzo ikakhulukazi ezindaweni ezingaphansi kokushintshashintsha kwezinga lokushisa noma ukunyakaza okuncane, okuqinisekisa ukuqina kwendawo esezingeni.
Ukugcinwa Kwamanzi: I-RDP ithuthukisa izindawo zokugcina amanzi zenkomponi ezilinganisa yona. Lokhu kubalulekile ekuvimbeleni ukulahleka kwamanzi ngokushesha okungaholela ekungangeni kahle kwamanzi kukasimende, okuholela ezindaweni ezibuthakathaka nezishwabene. Ukugcinwa kwamanzi okuthuthukisiwe kuqinisekisa ukuthi usimende ululama kahle, uzuza amandla afanele nokuqina.
Amandla Emishini: Ukuba khona kwe-RDP kuthuthukisa izici zemishini eziphelele zenhlanganisela yokuzilinganisa. Lokhu kuhlanganisa amandla athuthukisiwe okuqina namandla acindezelayo, abalulekile ukuze kuphile isikhathi eside nokwethembeka kwesisombululo se-flooring. Ifilimu ye-polymer eyakhiwe ngaphakathi kwe-matrix isebenza njenge-ejenti eqinisayo, isakaza izingcindezi futhi ithuthukise ubuqotho besakhiwo.
Indlela Yokwenza
Ukusebenza kwe-RDP kumakhompiyutha okuzilinganisa kungaqondwa ngokusebenzisa indlela yayo yokwenza:
Ukwakhiwa Kwefilimu: Lapho i-hydration futhi yomiswa, izinhlayiya ze-RDP ziyahlangana ukuze zenze ifilimu ye-polymer eqhubekayo ngaphakathi kwe-matrix kasimende. Le filimu isebenza njengesibophezelo esivumelana nezimo nesiqinile esibamba i-matrix ndawonye, ethuthukisa ukuhlangana okuphelele.
Ukupakisha Izinhlayiya: I-RDP ithuthukisa ukuminyana kokupakisha kwezinhlayiya ku-self-leveling compound. Lokhu kuholela ku-microstructure ehlangene futhi eminyene, ukunciphisa i-porosity nokwandisa amandla.
I-Interfacial Bonding: Amaketanga e-polymer e-RDP asebenzisana nemikhiqizo kasimende ye-hydration, athuthukisa ukuhlangana kobuso phakathi kwezingxenye zikasimende kanye nezinhlayiya ezihlanganisiwe. Lokhu kubopha okuthuthukisiwe kunomthelela ekusebenzeni okungcono komshini nokuqina.
Izicelo Nezinzuzo
Ukufakwa kwe-RDP kuzinhlanganisela zokuzilinganisa kuthola izinhlelo zokusebenza ezimeni ezahlukahlukene:
Amaphrojekthi Wokulungisa: Izinhlanganisela zokuzilinganisa ezithuthukisiwe ze-RDP zilungele ukulungisa izitezi ezindala nezingalingani. Bahlinzeka ngesixazululo esisheshayo nesisebenzayo sokufinyelela indawo ebushelelezi nesezingeni elifanele ukufakwa kwe-flooring okulandelayo.
I-Industrial Flooring: Ezilungiselelweni zezimboni lapho izitezi zingaphansi kwemithwalo esindayo nethrafikhi, amandla athuthukisiwe nokuqina okunikezwa i-RDP kunenzuzo ngokukhethekile.
Isitezi Sendawo yokuhlala: Ngezicelo zokuhlala, i-RDP iqinisekisa indawo ebushelelezi, engenamifantu ekwazi ukumumatha izinhlobo ezahlukene zokumboza phansi, okuhlanganisa amathayela, okhaphethi, nephansi lamapulangwe.
Izingubo zangaphansi Zokushisa Okukhazimulayo: Izinhlanganisela zokuzilinganisa ezilungiswe nge-RDP zivame ukusetshenziswa njengezingubo zangaphansi zamasistimu okushisa akhazimulayo. Ikhono labo lokwenza indawo ebushelelezi neleveli liqinisekisa ukusatshalaliswa kokushisa okuphumelelayo futhi linciphise ingozi yokulimala kwezakhi zokushisa.
Ukucatshangelwa Kwemvelo kanye Nomnotho
Ukusimama: I-RDP ingaba negalelo ezinhlelweni zokwakha ezisimeme. Ukusebenza okuthuthukisiwe kwezinhlanganisela zokuzilinganisa kusho ukuthi impahla encane edingekayo ukuze kuzuzwe ikhwalithi ephezulu efiselekayo, ukwehlisa ukusetshenziswa kwempahla sekukonke. Ukwengeza, ukuqina okuthuthukisiwe kwezitezi ezithuthukisiwe ze-RDP kungaholela ekuphileni okude, kunciphise isidingo sokulungiswa njalo nokushintshwa.
Ukusebenza Kwezindleko: Nakuba i-RDP ingase yengeze ezindlekweni zokuqala zokuzilinganisa, izinzuzo zesikhathi eside zivame ukudlula izindleko zangaphambili. Ukusebenza okuthuthukisiwe, izindleko ezincishisiwe zabasebenzi ngenxa yokusetshenziswa okulula, nokuphila isikhathi eside kwesixazululo se-flooring kunikeza izinzuzo ezibalulekile zezomnotho.
I-Redispersible Polymer Powder iyisengezo esibalulekile kuzinhlanganisela zokuzilinganisa, enikeza izinzuzo eziningi ezithuthukisa ukusebenza nokuqina kwezixazululo ze-flooring. Ikhono layo lokuthuthukisa ukugeleza, ukunamathela, ukuguquguquka, namandla emishini kuyenza ibaluleke kakhulu kuzo zombili izinhlelo zokusebenza zokuhlala nezimboni. Ngokuqonda ukwakheka, izindlela, kanye nezinzuzo ze-RDP, ochwepheshe bezokwakha bangayijabulela kangcono indima yayo ekudaleni izinhlanganisela zokuzilinganisa ezisebenza kahle nezihlala isikhathi eside. Njengoba imboni yezokwakha iqhubeka nokuthuthuka, ukubaluleka kwezinto ezisebenza kahle ezifana ne-RDP kuzokhula kuphela, kuqhubekisele phambili ukusungulwa nokusimama emisebenzini yokwakha.
